Its time to serve up a fresh plate of free components! That’s right nerds, this week we will be tearing down an old speaker circuit for parts. I already removed the main circuit and the speakers from the casing. The speakers popped right out and the circuit was unscrewed.
Now lets take a closer look at the circuit…
It looks like we have a large amount of capacitors (useful), some varistors (useful), a power port (useful), a potentiometer (very useful) and what looks like an AV in port (not so useful). The IC is basically useless, even if I could un solder it theres no point in using it. Now that the circuit has been analyzed and we know what we want to canibalize we can get started with the deconstruction of the circuit.
As you can see I have already removed some components in this picture, but basically I am cutting the PCB into smaller segments to work with. This allows me to be more precise in the desoldering. I will heat up the solder and then slowly pull out each component from its spot in the board. After only twenty minutes I was able to finish canibalizing the board and gained 11 capacitors of varying charges, 11 varistors of varying Ohms, the power port out, the AV out and the potentiometer (along with the two speakers already removed).
