« on: Sat, 31 December 2011, 13:27:32 »
Can someone open up their Noppoo Choc Mini and take a very close up picture of the 2 transistors closest to the cord connection on the circuit board?

Thanks in advance.

I blew mine up.  :(

You're a terrible person. Buy me a drink as consolation.

I should have tested that stupid cable before plugging it in.

Looks like 0.1uF and 10uF SMT capacitors, hard to tell what type though. Just make sure the voltage rating on the ones you buy to replace is sufficient. i can't imagine that you'd need ones rated for more than 10VDC...

Do you think that would fix it?

It would be cheaper than buying a new keyboard. You probably dont even need to replace them with surface mount ones, assuming you have enough room to fit a larger part in there.

I have enough room. I'm headed to Fry's Electronics right now to pick up the parts.

My only fear is that where it exploded, the board is kind of bubbled out, like it has a welt.

How did you manage to do that?

I modded mine for a detachable USB cable. The USB cable that I used isn't a standard cable, so i went online, got wire diagram, and made a wire.

All worked just fine.

I wanted "professional" cables, so I found some of the USB cables that I required, and ordered some.

Well, the cable I made, with the schematics I had on hand, was a cross-over of sorts. So, A went to D, B went to C, C went to B, and D went to A. The cable I got in the mail was a straight through, A went to A, B went to B, C went to C, and D went to D.

I plugged it in, and it didn't work. I thought that was weird, left it plugged in and grabbed the other cable and my multimeter so I could trace the USB, I realized it was reversed. When I  went back to my keyboard, I smelled burnt electronics, and knew I let the smoke out.

That's not good, if it delaminated, the board is toast.

Whoops, let's hope the controller has survived!

If the controller still works then some fancy wire-work might be able to get the board to a serviceable condition.

I think this is what happened, because even with the new capacitor, I just get blue lights.

There is a noticeable bubble, if it is delamination, can this be a possible solution?- http://www.circuitrework.com/guides/3-1.shtml

If you have the necessary tools and patience to do so, that looks to be a good guide.
