So for my second project I picked something to work on my soldering skills. A cmoy headphone amplifier seemed like a good choice. I managed to find a great web site explaining how they work and different parts I would need. Definitely check out “How to Build the CMoy Pocket Amplifier”. The tutorial made it easy to build. The hardest part was soldering all the connections to the switches and input jacks since I don’t currently have a third hand tool to help me hold stuff so it can get pretty tricky. Anyway here’s the result.


It sounded great and was loud enough that when I plugged in a crappy pair of earbud headphones and cranked it up it sounded like a set of speakers. Unfortunately I used solid wire which made the bending of the wires really hard and I was not able to shove it all inside an Altoids case. Either way it was a fun project and I figure I can probably re-use the potentiometer and switche in other projects.
