External battery pack for MT2496?
« on: October 10, 2005, 11:18:49 PM »
Does anyone have a design for an external battery to run a Microtrack2496? I thought I saw a post from Nickspicks but couldn't find it in all those pages now up on this unit. Thank you.

BTW-I compared the sound of my V3>JB3 @ 16/48/44.1 Ansr on and off and the V3 set to 24/48 to the MT2496 both digital in and found I liked he sound of the MT2496 much better. I was amazed at the 24 bit difference. Much more full, alive, and open.

I'll fluff Todd's work.  I bought a vr box and a modsbm-1, both are spectacular.

another one

http://www.dealsonic.com/usbbapabapof.html


I used that one, and I got it from compactimpact.com. Works pretty well, but I found it a tad too big.

Anyone try this one yet? http://www.gpscity.com/item-gps-city-usb-power-pack/batusbpower.htm
It looks pretty slim! Most importantly, would this even work? The pack says it puts out 6v when i'm guessing the MT only takes 5v.

I'm trying to get as much time as possible using phantom power, since I don't think the 2:40-2:50ish times i've been seeing in tests will be enough.

Edit: I remember someone linking to this one too that uses AAA batteries http://www.pearl.de/pearl.jsp?redir=yes&screenX=1280&screenY=1024 . That would be awesome if they shipped to the US... or if there happened to be a local place that sold them. I think I like the shape of this one the most.

I bought this one cuz it was cheap. The only thing I don't like about it is that the usb connector sticks out at a 90 degree angle making it a little awkward to deal with. Other than that, with the MT fully charged, I've been getting at least 7 hours of life out of the unit using cheap Energizer rechargeable (2500 mah) batteries recording 24/48, microdrive 4gb through s/pdif. I haven't had the chance to see what I can max it out at yet.

I got 2 of these, although from a different company. I'll echo whats been said. The USB plug is 90 degrees which kinda sucks, but I can deal with that. I haven't run any tests yet, but I bought 24 Energizer Lithiums on eBay for dirt cheap. I'm guessing I should get 8-10 hours with a Microdrive at 24/48 with a full MT charge and using this battery pack.

I don't know just where I'm going
But I'm gonna try for the kingdom, if I can

The fix for the right angle problem is a retractable flexible USB cable.  I got the one below from Chris at Sound Progessionals, it is far easier to run a compact rig with this than with a standard cable.

I will try 2500 mAh rechargeable Energizers, the Lenmar ones I tied punked out very fast, I thought this was a voltage drop issue but maybe I just had a bad set.  I have gotten over 6 hours total using a fully charged MT and Pure Energy alkeline rechargeables, and of course even better with lithium AAs.

Full set of pictures...
http://fecundswamp.peanutonastring.com/usb_batt/index.html

I made my own last night. All I can say so far is that it powers my MT. It outputs +5V on pin 1 and Ground is on pin 4 of the Female USB jack. From all I could read, that is all any of the new USB powered devices need. I hope it doesn't hurt the unit in anyway.

I used a Female USB "A" to PS/2 adapter I got with a mouse or keyboard. It had some rubber around it, after removing that is was easy to find nice wires. I got a 7805 +5VDC Voltage Regulator (1 amp) from Radio Shack for $1.59, part# 276-1770. I had a Sucrets container that seemed to fit the bill.

I also bought some 10mm Insulated Standoffs (Part# 276-1381), $2.79. I used one standoff to attach the 7805 to the case. The USB I hotglued to the case. This was suppose to be a quick and dirty test to see if it works. It does.

I followed the pinouts frm here http://pinouts.ru/data/USB_pinout.shtml and connected the positive lead form the batteries to the Input of the 7805. I connected the negative lead to the Ground of the 7805. The Output of the 7805 goes to Pin 1 of your USB Female Type A jack. Pin 4 of that jack then goes to the Ground of the 7805.

I used Two 9 Volts, the 7805 can handle a total of 35VDC, so that isn't a problem, I just don't know if you really need two... but WTH, more is better!!!!!

I am no rocket scientist folks, correct me if you are trained... all I possess is the power to read and some soldering skills. Here is another reference I used...
http://www.hackaday.com/entry/1234000270029372/

I will be testing the record time soon, using MP3 @ 128 my 2GB CF card says it will record for 35 hours... I thought I would leave it run till it shutdown, but do I really care if it will record for 35 hours? I mean, if it will stay on for a night of recording and listening in the car ride home, that would be enough.

I imagine the real advantage would be if you were not going to be ear a AC outlet for a weekend or if you are recording festivals.

Digi-key has some 7805's that look much than the RS one, and you can get PCB mounted USB jacks too...
1     10     497-2947-5-ND     IC PREC REG 1A 5V TO-220            0     0.97500     $9.75
2    10    ED90001-ND    CONN USB RECEPT TYPE A PCB         0    1.04000    $10.40

And I think the next version might have a nicer case, a Serpac M-6 http://www.serpac.com/products_m-6.htm

I hope to hear any suggestions or warnings you all might have.

be well

Patience, young grasshopper.  Even though the MT provides enough juice for most single-evening recordings (> 4hrs digi-in), I have a JuiceBox on the way b/c I don't like cutting it even remotely close on battery power - running out of juice is such a dumb, inexcusable reason to fail to capture a recording.  I'll post preliminary results after I get the JB.

+T ska, I read thru the runtimes pages and found it weird that a decent amount of folks seem to be running at least toddr's juicebox w/ the MT and didnt see any postings :) I did look in the right section and did research tho cause i truely am interested in this little thing

I'm sure the seamless track fix will be out before i can afford this anyway ;D

yeah ska, I would trust just the internal yet for sure, only about 3 hrs w/ phantom OFF I hear

Did you mean wouldn't?  I definitely trust my run-times with the internal batt, since I've run a few tests.  But for some single-evening performances, I'll still get a little too close to max run-time for my tastes.  I *hate* having to sweat about whether I'll have enough power, so generally go overkill on my batt situation.

I am using Todd's "juice box" with the MicroTrack.  I've got a 9.6V, 5 amp-hour NiMH rechargable battery for it.  so for, I've only used the setup once, at Yonder Mountin last week.  I'll be using it again at Club d'Elf this Thursday, and at Kottke/Gordon on Friday.  It worked great at Yonder, 1 hour first set, 1.5 hour second set.  I didn't power down the unit between sets either, so it was going the whole time.

I haven't had the chance to run a test at home to see how long it'll go.  but honestly, I'm not too worried.  While I'm not sure of the MicroTrack current draw when recording via the S/PDIF, the AC adapter that came with the MicroTrack is rated for 1 amp.  so it's got to be less than that.  others on this board have speculated that the current draw when recording from S/PDIF is 250 - 500 mA (pure speculation, I believe, but also reasonable speculation).  assuming it's 500mA, then theoretically, I've got 10 hours of record time with my 5AH battery.  if the actual current draw is around 250mA, then in theory, I've got 20 hours of record time.  either way, it's way overkill.  and that's exactly what I wanted.  Way overkill, so I don't even have to worry or think about battery power while I'm recording.

when I do get around to running a test for total time, I'll post my results.

i popped open the cover on one of the usb battery packs... this thing will be trivial to attach to a 6V SLA and get a lot more runtime than the 4-AA's would afford us.  it's all one small pcb with a usb plug already built in.

A couple of people have emailed me on how to wire the Fred Myer battery I use so here it is
pin 1 = 5 volts
pin 4 = ground

success

i used my BBP VR-Box that has 5v and 6v output and a 9v lithium "wal-mart" battery.





and hacked a mini usb cable i had going unused, and slapped a 4pin xlr on it




the mt shows the unit is charging






and here the combo also using the 6v out so i can also power my mp-2 or V2




great for open taping, but i am going to try to make a smaller version only for the microtrack like the sucrets box above. instead of using 9v batteries though, i think i will try to use 4 "AA" batteries (6v) so there is not much of a step down to the 5v required by the mt. i think it will save some battery power and also less heat

i made a smaller pack like the sucrets model on page 2.

i used an altoids tin, a 4 X AA battery holder ($1.69 at radio shack), the 7508 5V regulator ($1.59 at radio shack), and a mini usb cable (hacked) that i had lying around. the AA holder barely fit in the tin. i used a bit of cardboard on the bottom of the tin & some electrical tape on the solder board to prevent conductivity. i decided to hack a cable and hard wire it instead of using a panel mount usb connector, as i wanted to keep the cabling short. a little hot glue  was used to keep the wires intact and to secure the usb cable, and i drilled some small ventilation holes to (hopefully) dissipate heat buildup inside the tin. with this and the bbvr box in the post above, i think i have all bases covered.

I assume you mean 7805, not 7508?  Have you tested, yet?  Any problems running without a heat sink?  Do the 4 x AAs provide enough voltage for the 7805 to function properly?  I vaguely recall the 7805 needs +2v > the output voltage to function properly, but I could be mistaken.

I tested (livingroom) the record time of my new stealth rig with the following conditions:
DPA4061>MMA6000>MT2496
MMA6000 powered by 1 energizer 9v 150 mAh rechargable Ni-MH with gain set at 20db
MT(fully charged) with the http://www.bixnet.com/usbbatterybox.html USB 5v (4 AA) box using energizer 2400 mAh AA rechargable Ni-MH with recording settings set to Monitor(off), BitRate 16 bit, Sample Rate 44.1 kHz Format MP3 (Used this resolution to ensure it had enough room on 2GB Lexar 80X card to run until it died) it showed initial available recording time as 36 hours or so.
I shut it down this morning after it was at 9 hours.Will run until it dies tonight unless I actually go use it to record at a local coffee house.
When I unplugged the aux power the MT battery indicator showed half full. The gain of the recording was still up at the end and the green light on the MMA6000 was still flashing, indicating it was still providing adequate power.

Just FYI, I find that the MMA6000 will run about 24 hours on a standard 9V.  The exact time doesn't matter, because you will get about 3 hours more while the red light is flashing, so even if it reaches the point where the red is flashing in the middle of a concert, you're probably going to be okay.

Thanks Jeff...now that you mention it, I recall reading the 24 hour thing. I just wonder how the rechargable compares to the regular 9v. I don't think this would be a weak link at all. I am just trying the cheapest solutions for the MT first to see if I want to go the big lithium battery route with a juicebox or something like it to power them both. I think this little set up will work fine for me.
NOW all I have to do is practice shoving all this shit down my pants. ;D

Just a note on the Altiods/Sucrets/DIY versions. If you use two 9 volt batteries, run them in parallel to keep voltage ~9. In series, you will be giving your regulator 18v and making it drop 13v to get your 5v out! Most of your battery juice would then end up as heat emanating from the regulator.

Also, and I forget where I read this so judge my credibility accordingly, the fixed regulator IC's like 7805 and 7812 are supposedly much noisier than the adjustable ones like LM317.  Power supply noise can be a big deal (and probably accounts for a lot of the MT's own noise). Possibly not in this case though, as it's an external supply and battery only (hence no AC or rectification etc.), but just something to be aware of. LM317 is a bit harder to implement as well, requiring an extra resistor and fiddling to get your exact output voltage.

interesting.  a noisy power solution probably only matters for people who are planning to run analog into the unit.  for those of us running S/PDIF into the unit, whether or not the power supply is noisy, as long as it records the ones and zeroes, that's all that matters :)

Len says "With the 7805 you should use a tantalum cap on the input side for filtering and an electrolytic on the output for stability."

My question, and I will ask here first, is how to best figure out the Capacitance to use. One of teh datasheets for a 7805 I read said 22uF, I have seen others mention a higher cap mentioned.

How can you best figure out the capacitance required?

Just a note on the Altiods/Sucrets/DIY versions. If you use two 9 volt batteries, run them in parallel to keep voltage ~9. In series, you will be giving your regulator 18v and making it drop 13v to get your 5v out! Most of your battery juice would then end up as heat emanating from the regulator.

I learned that AFTER I made my version 1 in the Sucrets pack. I have read a lot in the last few weeks.

The goal of version 2 was to be smaller, use ONE 9V rechargeable, use an input capacitor and use a tin case with the 7805 using the case as a heatsink. I learned during the creation of USB Battery Extender Version 2 that I should have some polarity protection, but it was too late to incorporate it at that point, it was 2AM! That would have ot wait for Version 3.

So, it was later and I was moving along and being a humble man I will now admit, in public... I F'd it up and had made the space for the battery too small and here it was completed and the 9V batt would not fit. DOH! I had been so careful, but in the end I failed. I put it aside and figured, "eh, lesson learned" and went to get a new 7805 to begin Version 3. I had to grab some more 9V batt leads and noticed a holder for a "N" battery, it is like a 1/2 size AAA. I asked the guy what batter it held and they had several, from 3.5V to 12V. I thought what the hey, it would allow me to salvage the Version 2 that the 9V doesn't fit in.

This is Version 2... http://fecundswamp.peanutonastring.com/usb_batt_v2/






The battery has a little nook built in so it can be store in the bag for transport
when not in use.


You can see the screw that attaches to the standoff that attaches to the 7805...
this will act as a heatsink... I hope!


The lid does shut, it just isn't in this picture... I thought I was doinked when I realized
the lid did NOT shut after I installed the USB adapter... a quick zip with teh dremel
cutting tool an it shuts perfect.


I used the PS/2 to USB adapter again, I always knew that they would be useful someday. It has a 22uF Polyester Film Cap on the input, it uses a 10mm Standoff to connect the 7805 to the board & the tin, acting as support and as a heatsink. And this has no polarity protection, but it isn't so important now as it uses the Type 23A 12V battery. I will probably use this once and then never again, unless it lasts a really long time... the battery is like $3.80... but it really made me laugh that I could save my failure from utter uselessness. I wish I could get these in rechargeables.

I found this site useful for helping me understand the reverse-polarity issue... http://www.maxim-ic.com/appnotes.cfm/appnote_number/636

I wish I could find a site to explain how to figure out what capacitance to use though. The datasheet for the 7805 shows a 22uF cap on the input, so that is what I used... I have no idea if that is good or bad... I am dangerous, aren't I? Just enough information to F everything up.

thanx,
michael

Hey Michael. That's certainly a compact battery box, but, especially with one little N battery, I wouldn't think it would give you enough extra runtime to be worth the trouble. A few other observations, which you should urgently ignore if you wish  ;) :

Just as with two 9v's in series, using a 12v battery into your 7805 is very inefficient. You do need some 'overhead voltage' to make the regulator work, but only around 2v. With 12, that's about 5 of your 12 volts just wasted as heat.

A battery's physical size is a rough indicator of how long it will put out juice for. That tiny N battery won't run your MT for very long at all. A 9v, quite a lot longer. A few 9v in parallel could make a very worthy external juice box for a MT. For serious amp-hours, your big, boxy, heavy SLA's are the business.

I sounds like you mounted the 7805 on a standoff, away from the floor of the box. For best heatsinking, the flat back of the chip should be in full contact with the metal, with some heatsink compound smooshed in between. It might not matter in this case because the MT probably draws way less current than the 7805 can actually handle. Especially if you don't drop a bunch of extra volts across the regulator!

I'm not sure whether a momentary polarity reversal will fry the 7805. I kinda don't think so. The datasheet may say. As long as your juice box won't implode if you accidentally touch the battery leads wrong way around when you're putting in a new one or whatever, I wouldn't worry about hard wired polarity protection. Just dont have your MT plugged into the juice box whilst changing the batteries. Once they are in right you should be fine because the USB connector only plugs in one way.

I think the smoothing cap value is not critical. Pretty much bigger is better. 22uf sounds pretty big to me, like that datasheet is pretty conservative. Especially since you're running from battery so there won't be any AC ripple trying to get through.

Peace,
Sanaka

Thanx for the feedback.

Like I said, this was me trying to recover after a terribly landing. It was late and I drilled just 5mm too much to the right when i should have drilled left. When I realized the 9V didn't fit, I was going to trash the whole thing. Then I found this battery, so for giggles I finished with it.

I had thought about putting the 7805 against the bottom of the case, and I agree, it would be more effecient... I may incorporate that into Version 3. Thanx!

I understand the AC ripple thing, I read that... as a matter of curiosity though I do want to understand a bit more about what values to use. I think what I am heading towards, is there a way (or need) to regulate the input voltage so when input power drops to a certain level it shuts off... or does the 7805 do that? I know the 7805 'wants' a min of 7V in, but what if the battery drops to 6V? and then even to 4v? does it simply shutdown when it can no longer output 5V?

For something I could buy for +/- $30, I am probably overthinking all this.. but I am just curious... I want to understand this stuff better.

I would also like to add to my design... a LED that is either on or off, if the power drops below 5V the LED does not light indicating battery change needed. maybe disco lights? mirror ball? ok, overthinking.

good night.

Again, I appreciate the feedback

...I think it is because the 7805 needs at least 2v headroom for the regulation to kick in (read from another forum) but please correct me if i'm wrong.
Just get a more modern low drop regulator. Linear and Maxim have them.


BTW: got info about a nice external battery, info is at http://taperssection.com/index.php?topic=55120.msg735397#msg735397

I found that in the USA the battery stick I wrote about (see link) may be marketed under the I-Power brand as Multi-Purpose Charging Stick.
With this small battery we'll have no worries about long shows, festivals, etc.
Has anybody found the device on sale somewhere online?
Please post!

I think i'm confused?  is the battery you speak of one that fits into the MT or an external battery pack?

I guess I'm somewhat lazy, at least too lazy to pull apart the MT to replace the battery.  I myself would rather just use something like the battery box posted on the first page: http://www.bixnet.com/usbbatterybox.html or a juice box (todd r) type device if I need power for all day at a festival.

An external device might be more cumbersome to some, but with me and my hands, pulling apart the MT and moving circuit boards to replace the battery seems like trouble waiting to happen.

Another thing to consider would be, if you put a larger battery inside the MT, would it still work properly?  I don't know much about powering, but could it be possible that the MT is only regulated for that size battery?  Also, would the battery get too warm and then end up melting something on the inside?


Because nothing says "I have lots of money and am sort of confused as to how to spend it" like Bose.

Yes, that is why I also mention it here.
My initial quest is/was for an internal battery replacement.

For external I have the Bixnet USB box which uses AA's.
Also for external I found this battery stick, that's why I post it here as well.
Sorry for causing confusion.

I picked up a couple of the Digital Concepts PP-99's, described earlier in the thread.  While I haven't done a run-2-dead test with them, it appears they'll run this thing a LOOONG TIME for a small package.  I've run it 4.5 hours, backlight on all the time, and still had 2 lites left on the battery.

Shenzhen Herocell has a Battery Stick of 2200 mAH at 5V which could work great with an MT. I am trying to obtain one.

Edit: Their site should be more functional after january 15th.

I have a USB 4AA battery pack for my M/T...........I also have an external ipod shuffle 2X  AAA battery pack that has a USB plug.....Haven't done any run time tests just yet but it should get me thru the first set without touching the internal battery....every little bit/amp helps...Peace

I didn't see in his thread that he offered that but if he's making you one I can't imagine why he wouldn't do the same for me.  I'm in the process of getting some XLR(F) > 1/4" TRS(M) cables from him so maybe I'll ask for a custom USB cable for this charger as well.  Thanks for the pointer +T.

...here is a ziplinq usb car adapter modded for RC packs. The adapter was bought at Frys for $4.99 and the RC plugs were bought at Rat Shack for $.99 (open package deal). I was first going to gut the adapter and replace into a project box, but the end where the plug wires come out unscrewed and the case popped open nicely so I left it intact. I took out the metalware and soldered the plug wires, recovered the case and there you have it. Works like a charm for my MT

If I read the specs on this thing correctly, it will let you run the MT2496 for as long as you have sunlight plus an additional 4 or 5 hours, making it perfect for festival recording among other things:

It even comes with a mini-USB connector, so no hacking required!

Very cool... I am still enjoy the hacking though... I have a JVC digital camera and picked up these 7.2V 3500mAh batteries real cheap for a trip I took over the summer, I don't use them much now... so I wondered how I could use them for running the MT... Energizer makes this universal charger (ENERGIZER ER-CH1 SPEED CHARGER FOR CAMERA BATTERIES) I got it used for a couple bucks, it has various adapters for the different model batteries... they open with 2 screws and have lots of room inside, so I threw this together a few minutes ago... http://fecundswamp.peanutonastring.com/usb_batt_v5/index.html


I think this one wins in the power vs weight arena... I had two of these batteries and bought two more for my trip and 1 battery ran my camera with the LCD on for almost 6 hours... I think it would run the MT for a long time.

I only have JVC batteries... there are 3 other 'adapters' that I don't need, if any wants them, message me...
1. compatible with Panasonic CGR-D120, CGR-D220, CGR-D08A/D16A 7.2 LI-ION
2. compatible with Canon BP-511, BP-522 7.4V LI-ION

It uses a Neutrik USB Panel mount...

That sure is nice!

So you're using a 7.2v battery?  Does the box that houses the USB panel regulate the voltage to 5v?  Wouldn't 7.2v be too much for the MT?

Thank you.

So you're using a 7.2v battery?  Does the box that houses the USB panel regulate the voltage to 5v?  Wouldn't 7.2v be too much for the MT?

I am using a 8 AA battery holder... which is 12V. I didn't have 8 recahrgeables charged, so for testing there I was using alkalines. The output is 5V... I am using the insides of a Ziplinq usb car adapter... check back a few posts in this thread for a picture I posted of the unit cracked open.

I desoldered the LED and soldered some leads onto it so it could be mounted in the top left hole of the Neutrik connector... the connector is quite snug and the single screw should suffice to hold it in place.

The blue caps that the mini-toggle is mounted on are from the inside of those giant 5 gallon water jugs used on water coolers... I like to collect weird things just for such uses.

The box is $1.50 pine crafts box from a craft store and I used a 1-Step Polystain... 2 coats.

I will post the link to the page with a review of all the various power solutions soon.

Ok group, I took my Mt out last night for her maiden voyage. everything seemed to work fine using 1g sandisc ultraII cards running 16/44.1. I did get somewhat concerned about the battery life and I want any or everyones opinion on what is the absolute best external battery setup with preferably a very small foot print.

I found this out... if you are good with a soldering and heat shrink and even with a limited understanding of electronics (as is my case) you can easily make a simple battery extender that will run the MT. If you are NOT into the hacking idea, the the Digital Concepts PP-99 is the way to go... I waited till buy.com sent me a nice coupon and got mine cheap... Buy.com Sku: 90146586 (they are sold out at the moment, search froogle.com maybe). If you get this unit, you will need a cable to go from a Size "N" Coaxial DC plug out of the PP-99 to a usb mini 5 pin to go into the MT, I believe Todd R can help you with that if you are not comfortable making one... see http://taperssection.com/index.php?topic=49744.0 . Radioshack sells the plug for $2.59 and it is crap... Part# 274-1573, I have not found a nice right angle one yet, Digi-key.com has one made by CUI (PP-002B) /  Digi-Key # CP-004B-ND . You can then take a USB cable, USB B 5-pin mini, http://bgmicro.com/prodinfo.asp?sid=089682870370370470110216171&prodid=CAB2112&page=1&cri=usb&stype=3 and solder the positive to the center of the plug and the negative to the shield.

There are more and more products hitting that market to extend the battery life of the iPods that also use the 5Volts... and many have a simple USB output that makes life very easy. This one has a LED flashlight built in... http://www.semsons.com/unbaexwiusbp.html

If you want to give it a go yourself, it really is quite simple, read this http://www.tkk.fi/Misc/Electronics/circuits/psu_5v.html and this explains the USB pinouts... http://pinouts.ru/data/USB_pinout.shtml

I am going to detail all the hacks (and products I found) at this page... http://fecundswamp.peanutonastring.com/usb/index.html right now it is just the pictures, I will fill in the text in the next week.

I hope this helps.

be well,

Last week my Shenzhen battery sticks plus various adapters and two chargers arrived.
They are about as small as my thumb (length) and are about two fingers wide.
They provide 2200 maH at 5V. i.e.: double that of the MT.

After charging I will test one out and see how long they last.

Just got a Toddr Juicebox from YS (bagtagsell's sale thread) and hooked it up to a 9v 6000mAh li-ion battery.

I think I'm good to go.  ;D

So I got my Shenzhen made Battery Sticks (2200 mAH at 5V or so).
What us the best strategy to use them or any battery pack together with the Microtrack?
Connect the charged battery, start up the MT and record?
Or start just the MT and later connect/power on the batterypack when the MT's battery drains?

What is possible? What is best? (if there is a difference  at all)
I just need the longest continues recording time with the battery capacity I currently have.

in my testing with both external batteries, I connected a fully charged battery to a fully charged MT and let them run

the external batteries ran out first and then the internal MT battery took over from there

     In moving my DATs over to my HD I used the MT with the wall wort.  When I had to change the Compact Flash it would always fail to find the media when I powered back up with the electric plugged in.  If I powered back up using the internal battery, no problem.  So, when I have to change the compact flash, I always power back up without using external power.  I just plug that in when eveything is already going and I have a little time.

I have found this to be true also. I can not change CF cards WITH the charger plugged in... I think it has to do with the fact that the charger boots the unit, and keeps it in some kind of "standby"... so, if I need to change cards I have to power down the unit, remove the charger THEN change the card and reboot... I can then put the charger/battery back in as needed.

I am putting my battery in first, let it boot into charge mode, press delete to boot to active record mode then I can begin to record... I found that plugging the charger in while it is booting will just lock the record button... i could do everything but press record... I removed the battery, rebooted and it was fine... I then put the battery back in and everything worked as expected.

So I guess the answer is, either BEFORE or AFTER but not during startup.

Bought 2 of these ($10 each) last week. They arrived 2 days later.

I'd love to post run times/performance/etc., but my Microtrack is completely fucked up, so no luck there...

Thanks. I just picked one up.

That is really useful information. I did not know you could go from charge mode to active record mode by pressing the record button. I have always waited until after booting up, but sometimes when the second set of a show is beginning, I forget the battery pack is in, and I have to power down and back up. Thanks blindman for the useful tip!!

Would this work?

Is 5.6v correct?

I've used one of these and it works great. But ther are cheaper prices.

I got mine off eBay from these folks for $.01 and even with $10 in shipping it was a bargain. The Flashlight comes in handy as well.

i just finished reading most of the threads on this topic but i'm still unclear on one thing...  when using a fully charged MicroTrack and an external USB battery box - what happens if you're recording and you unplug the battery box?  and then what happens if you're recording while using the internal battery and you plug in an external battery box?  does either situation cause the recording to stop and/or hiccup?  and can you continue to monitor the levels the whole time?

i would assume it's the same answer as when using the included AC power adapter, but my MT hasn't arrived yet so i can't test it.

Usually nothing happens connecting or disconnect of USB power, before, during, or after making a recording. 

However, on very rare ocassion the deck has shut down when USB power is disconnected.  But this is the exception and seems to not be repeatable in my experience. 

USB power has NO jack disconnect switch built in so only thing that happens is +5 volt power either appears or disappears from this port while the internal Microtrack battery continues to be on tap for deck powering.  USB power seems to either be applied to powering the charger, but not necessarily soley assigned to power the deck like usual with AC adapter-powered instruments. 

If this is truly the case, then whether the deck has USB power applied or not should make NO difference as long as there is a functionally charged battery inside the deck.  Keeping USB power applied, the deck will appear to shut down, but is actually still running with a blank screen and drawing ~.21 amps.  With USB power, the deck 'instantly' turns on and starts recording with pressing the Power and REC button in quick sequence.  This can be handy if in the field and wanting to avoid the 20 sec boot delay to initiating recording. 

To this end, the BD-MT Power Sled available from my company www.sonicstudios.com/batsys98.htmallows keeping the deck powered for over 56 hours in standby or recording on 6 D alkaline cells.  Perfect for a full week of music festival or ambient sounds recording.

all the links I've tried have been dead so far, or something entirely unsuitable for stealthing.  I don't need 50 hours worth of time, just a couple extra "just in case" because I don't want to blow a show just because I wanted to tape the opening acts as well as the main act and keep the unit powered up between sets.

Here are the rest of the boxes I made... http://fecundswamp.peanutonastring.com/usb/index.html

Rough Instuctions are here... http://taperssection.com/index.php?topic=51864.msg687527#msg687527

but that was my first try and it sucked... use one battery instead of two and get the Altoids gum tin.... you will need a dremel tool to cut the side and a USB-to-PS/2 adapter that comes with mics and keyboards... any questions feel free to PM or email me.

You want the easist cheapest way to go? get one of these somewhere... http://fecundswamp.peanutonastring.com/usb_carcharger/ I got this one for $4 online but my wife bought me PSP add-on gift pack and it had one in it.... get one, don't even crack it open... just put a 9-V on the end, tip +, and the - on the side and you will get a 5V out to go to the MT with a regular 5-pin mini USB cord.

wow, they only have a $10 one now...

just adding this that I posted on another thread.


this is what i use...

http://www.laptoptravel.com/Product.aspx?ID=2019
http://www.powerstream.com/dc6.htm

cut the cords, put a quick disconnect on the 12volt side, put a USB mini(red and black wires) on the other side, set switch to 5v, done.  hook up a batt of your choice, up to 12v, on the batt side w/ the quick disconnect.  basically, a ghetto VR box.  I run mine off the 9v Walmart batt.

Here is another one.  Just ordered this stuff after consulting with the tech support.  All products are made by Pocket PC Techs, Inc.


4AA battery power unit with a regulator circuit switch to supply a constant 5v output to the device, regardless of lithium, rechargeable, or alkaline batteries. - $20

http://www.pocketpctechs.com/main~unit~iMATE_JAM-281~area~accessories-Power+Accessories~item~USB-BATADPT01.htm


Retractable male USB > USB mini cable to connect the above battery supply to the device - $20

http://www.pocketpctechs.com/main~unit~iMATE_JAM-281~area~accessories-Power+Accessories~item~USB-LILSYNCP01.htm


Shipping is kind of expensive at $10, but probably worth it for a non-soldering person like myself.


EDIT:

More of a "for the record" thing than anything else, but I ordered the above items and used them at the ABB shows for the past two nights.  I used the MT with a 4GB microdrive for about five hours of recording time with 4AA alkaline batteries in the pack.  Worked flawlessly.  I have no idea how much longer I could have run it, but I only got about 2 hours and 20 minutes with just the MT internal rechargeable and a microdrive, so this is definitely an improvement.  I charged the MT up all the way and then connected the battery pack with 4 fresh AA batteries in it for the shows.  An issue with the battery pack is that it does not have an on / off switch so I had to physically remove the AA batteries from the pack during breaks and stuff to conserve power.

The sound professionals have what you need specificly for Micro Track  1 for $49.00 and the other for $59.00 Say's adds  7+hrs for the one that is $49.00. 8+ hrs for the one for $59.00. So far I picked up the Micro Track mic they made and it is sweet. I'm waiting on the battery pack to come in the mail. I love my MT. Have used it many times for live recording. No complaints.

ADVISORY: There is NO exact battery size stated, or just what type of regulater (efficiency?) is being used to maintain the 5 volt output from 3.7 volt lithium cell battery. 

If battery size is 1000 ma, then run time with fully charged MT internal battery is less than 4 hours BEFORE needing to use up the internal battery of the MT deck.  Because regulaters are NOT 100% efficient, likely less time, like maybe only 3 hours additional time, and only if MT battery is already fully charged before connecting the external battery device.

This gives total ~7 hours run time where 3 hours is the external attached battery, and maybe four hours is solely from MT internal battery if its in TOP condition.

If the MT battery is NOT fully charged, then the external battery may last only 2 hours before needing the internal MT battery to take over running the deck.

Somebody needs to actually run this external pack and post the recording time available.

I'd be curious to know what the capacity of this battery is, as well.  That said, the specs don't say 1000ma-hr capacity, they say it can only supply up to 1000ma of current.  So if your equipment draws more than an amp, this battery pack isn't for you.  Not an issue at all for the MT (which is something like a 250ma draw??).

At least in the linked webpage, it says nothing of total capacity.  I'm hoping the battery has at least 4000ma-hr of capacity -- anyone know for sure?

I found some specs on the web that said this pack is 3400ma-hr.  Be careful not to get the smaller version which is about half that and still $29.99.  I cannot find it now but there is a post somewhere on this site from a user saying he was getting 6 to 8 hours extra.  I will be doing some festival taping next week and I may need an extra 2 or 3 hours one day so I will see how it works.  I ordered from the new egg site and it came in 3 days.

Here's a thumb sized external I use with the MT.  Haven't really tested it for combined length but I can leave an average length gig with a full internal on the MT. 

Ships from Ireland I believe and may be a bit pricey at nearly 50 USD

I used this battery (http://www.newegg.com/product/product.asp?item=N82E16855998033) for the first time saturday night and it works pretty well.  It ran the MicroTrack for about 4 1/2 to 5 hours and then I plugged a second one in.  I wonder if you can link a few of these together...so using the USB out of one into the mini USB of another, from there go USB out into the MT

That is the CH-430... my local Wal-Mart has a few of them also... $10 for a charger like that is a great deal.

These are made by Sakar, Inc. and the Digital Concepts brand seems to have become i-Concepts... the new version of the Ch-430 is called the iStick and comes in iWhite and costs i$30 :)
http://www.compusa.com/products/product_info.asp?product_code=344123 and I can not tell if it comes with the retractable cord.

There is another ipod charger from Sakar under the iConcepts brand that is in a different shape, the 23188C-IP and has a retractable iPod charger instead if the mini-USB version in the CH-430. http://sakar.com/products-features.aspx?PARM_ID=101043

Anybody figure out how to replace the [non-user serviceable] battery in the Microtrack?  I'm game for soldering if need be.

Has anyone had trouble using this battery?  I used it to power the MT so I could run for 3+ hours at 24/48.  Thought I had it fully charged for the first try, then noticed after about 15 minutes of the show that the battery was dead.  Charged it over night immediately prior to the second try, and confirmed it was fully charged.  Ran at 24/48 again, and again, in the first 15 minutes, the battery was dead.

Do I have a short somewhere?

I just want to make certain... If I'm using one of these 4AA USB battery packs with alkalines, do I need a 5V regulator? or will the MT work OK on full 6V?

Its my understanding the rechargeables won't work very long either since they drop below 5V pretty fast?

got about 10 hours (between the external and internal battery)....YMMV

akg480/ck63 > Opti-Mod V3 (24/48) > MT 24/96

this is the external battery:

Hey dude, I have one of these battery's but it has been shitting on me for my last couple shows.  Can you tell me, do I need to charge this thing with the power on? The foreign instructions suck!

Thanks.
