We want a P10 single colour led controller designed with a STM32F4 based device or similar - we want 8 x HUB12 ports. It MUST support greyscale / brightness control of each led - 8 bits per led. We want to be able to show images, text, animations and greyscale videos
...intervals. Since the ATTiny does not have a random number generator, you will need to develop a way to create pseudorandom on/off times as part of this project. The Tiny10 has two PWM outputs, so you will use these to control two LEDs. Each LED needs to have an independent on/off timer that turns the LED on after a random delay of 5-30 seconds, then keeps

I am a keyboardist and since I get to travel a lot by plane my dream keyboard would be a mix between the CME xkey, cause it's very thin, and the Role Seabord block, only cause it's modular, so it means that you can split it in variable sizes and able to expand it being magnetic on the sides. It would need also some faders, knobs, pads like the Korg nanoKONTROL2 or using touch strips. I...
