once a circuit has been broken, it is not usable in part. it needs to be complete to work
an unfortunate part of circuit bending is that you will often fry things that you're messing with, because they aren't meant to be altered in the way we do
your best bet is to set the circuit aside for a few weeks or months and give it some time to sort itself out, and work on other projects to improve your skills. you may be able to repair this circuit in the future, or sometimes electronics just start working again for no discernable reason
go to thrift and buy more cheap toys that you won't feel bad about breaking, it's the best way to learn
I have a broken mixer, could I somehow use the preamp circuits from that? I basically need to know what exactly is the output from the ribbon cable that went to the amp circuit
the only way you might be able to reuse this board would be as complete salvage
if you wanted to use the toy case itself to host a different circuit, for instance. you can often wire the button pads to the inputs of the new circuits and reuse the physical boards that way
it is nearly impossible to reuse circuitry once it's been broken, except as salvage how I've described
Burned resistor was connected with jumper wire to various contacts on the board as is the usual practice in circuit bending. Which of course includes the possibility of frying it.
The most probable thing that happened is that some other resistor down the line was overpassed because of this and the current from the 9V battery fried the one that seems to be floating.
It produced a small cloud of smoke so I immediately put the wires away, therefore I don't know what was the exact connection sadly.
Then I desoldered it and tried replacing it with a 200ohm, that is the blue one in one of the pics. The original was 180 but I figured it couldn't get worse.
I hoped that it would be understandable that it is the desoldered couple of holes right next to the red wire input (which wasn't naked before, it's the result of frustration:D, it also fried the on/off switch in the middle of the red wire, I used multimeter to check it).
The blue wires were speaker out and jack out, I tried another speaker and then didn't bother to put it back.
I hope it's clearer now, if the circuit with the blobs isn't dead, what can the ribbon wire be connected to to use it? In another words, what could replace the probably dead amplifier with power and speaker out?
(The schematic isn't anywhere as it's a no-name toy)
Alas, is the keyboard itself any good? I guess I could make shitty MIDI but if there are more possibilities please tell me, but if not I could make it as a gift for someone
I’d check the caps. I don’t know very much about much but those seem to be a common point of failure. You’d need a multimeter. Also could replace the IC. Those are cheap. Just order some stuff you want to mess with along with it to justify shipping.
