In my humble opinion, I think 2x 22uF won't hurt USB powering devices. I have often added capacitors to limit noise up to 100uF, without troubles for now. Some circuits inject so much noise in power rails, like little class D amps (pam8403), oled...
I had good results playing samples with playMem. You have to prepare your samples with wav2sketch. I suggest 16 bits, 22kHz.
The problem is that the memory is going to be full very quickly. This is perfect for a drum kit, with short sounds. But...
Hi,
I would encourage you to go with the "synth approach" as well. Could you tell us more ?
- do you want to build a monophonic or polyphonic synth ?
- what kind of keyboard do you use ?
- do you want to add a lot of knobs and switches ?
- do you...
I will certainly add a switch to choose the orientation of the pitch.
I have tested it quite a lot now, and it is really fun to play. There is of course room for improvements ! I have used a VL53L1X sensor to mesure distance. I appears to be a...
These amps are really a pain. If noticed also that some of them, depending of the supplier, are not exactly the same. Some avec smaller caps and tend to produce more noise. When you insert a cap, be sure to solder it directly on the amp, on + and...
Hi,
These class D amps inject terrible amount of noise in power rails. The are in fact very difficult to use. I say that, but I use them a lot, since they are so efficient ! I can get rid of the noise doing this :
- try big cap (100 to 200uF) on...
Hello,
Here is another Theremin ! This one is very simple : a Time of Flight sensor for the pitch, and FSR for volume. The synth section is also very simple, just one oscillator, a LP filter, minimalist LFO and reverb. In fact, this project is...
