Dissecting the Radio Shack A/D converter...
« on: February 13, 2005, 12:08:00 PM »
Not sure why...but just to see whats inside this cheap thing.

Well - easier said than done...

Im not sure I've ever seen anything put together this well...

Im not sure I can actually get it apart...!

It's totally soldered shut...and when I got as far as pic - the board is soldered to the case - like 2 inches of seam - all solder...

I used some solder absorbing braid - that worked well...Incredible they used so much solder in this thing...

Should I go any further?

Thanks for showing us the insides, its a shame that this thing isn't better a/d quality with the type of construction and size, it could make a nice a/d. Is it possible to switch out the toshiba chip for something more suited to our needs?  I don't know much about that just throwing out the idea.

That is a great idea, if you could stick a brown burr A/D chip in there it would be a dramatic improvement in quality.
+T for taking stuff apart

Is all of that shielding to protect from RF noise?

What specs do you see that aren't so hot?
