Hello sir thanks for sharing this nice build.Where did you find the motor shaft adapter ....having trouble finding one ...
Anyone Can Make This 10W+10W Amplifier
Thanks for your interest and recommendations. As it turned out you are correct about the power supply (my benchtop uni-t) was causing quite some distortion. So I switched to the 12V battery which really helped a lot. I also took your advice and added a couple of 1K (you were right about the 10K-47K range) resistors to the stereo input capacitors which also helped and I got it to work with almost no distortion at max volume level. Thanks a lot for your time and help on this man. Peace
I can't thank you enough for this helping/reply.I needed a friendly-diy-soul to tell me that I didn't purchase those 2-20W speakers in vain LOL. I mounted a 220uF low impedance capacitor (meant for audio applications) directly and as close to the 12V-GND pcb holes. This took away quite some distortion but still some remains and it's still noticable but it's acceptable in my case. Also tried a bigger capacitor but didn't seem to make much difference. Your instructuble is a highly portable (not only) solution for my korg volcas and other diy synths. Thanks a bunch again! Peace
Thanks for sharing man.Only thing I made a mistake I guess.I used 2x20w 8ohm speakers.Im not sure of the impact but still works.Adding a 220uF decoupling capacitor between 12v-GND to eliminate hum ...
The beauty of simplicity man. Thanks a lot for sharing and for your precious time to give us this great instructable.Now I enjoy this stand with minimal footprint on my desk and great usability.
Thank you very much for your time to read it. Yes It did! Better than I thought it would.
Thank you very much!

you can just ommit mm and replace with cm like : 42.2 mm is actually 42.2 cm or of course 424 mm

Congrats for the build. Electronics at the service of people's health not just for fun... Try making it internet independent (with an A6 module for instance) for maximum convenience and portability. Thumbs up for this great project. I will be making it.
Congratulations for this very beautiful and fun build. This goes to my Christmas tree for sure The code works without any modification ONLY with a common cathode matrix. You will have to change it to make it work with a common anode matrix. At first i saw the original schematic and i used a common anode matrix but it didn't work. I was too lazy to modify the code so i've tried a common cathode and voila! My led matrix display is KWM-R30881CUYB which is a common cathode.
I had the same problem and tried the same things buuut.....it's the pin assignment to in the sketch which is wrong. Change it accordingly. The sketch pin assignment does not correspond to the schematic actual connections.
