Im going to build a high powered custom LED strip for the wacom and anything else

1 Comment

Ive drawn up a model of the LED strip i have in mind. It is based on a 5.7mm long SMD LEDs, prefferebly 5736’s, but they arent too common, i may have to go with 5730s. I was going to go with the 5050s, or another LED but packed tighter, however, 5050s are a tad bit too big for the rails without going into multi layer PCBs which are just insanely expensive. I was also going to go with packing heaps of LEDs on the strip by turning them sideways, but, same reason, i couldnt, so ultimately this will end up being a modular larger version of the exact same strip. not that its bad or anything. this strip though will utilize parallel series of 4 instead of 3, meaning it can be safely run at 12v unregulated.

Arduino, MIDI with stm32f103c

STM32 based MIDI synth

I realized the STM32F103C i have has a pretty high clock speed, so currently im trying to turn it into a basic FM oscillator synth. In other words, it will read midi input from another device, like piano, midi controller, etc, then convert it into sound.

I am using this library https://github.com/FortySevenEffects/arduino_midi_library , its as its described, basically plug’n’play, though there is a small number of tweaks and understanding to utilize this as i have found, not just for the stm32, but any board you use this with, less so though for the UNO R3
