Recently I decided to try out a few starter projects. I got started with this one thinking it would be a relatively easy first project, as well as afford me a portable solar powered charger and amplifier..
I started out assembling the audio amplifier card:
Fully assembled board.
The next step was hooking up the speaker, the audio in and the power for the amp. I used a microphone cable and plugged into the headphone jack on my keyboard. It all equaled a lot of alligator clips as you can see. But it does all work.
The next step will be deciding if I want to make it fully/partially solar powered and bluetooth or headphone jack. I have so many projects that I want to make, I might just get this wrapped up as quickly as possible so that I can move on.
