PreciPSU is an attempt to build high performance power supply. The idea started few years ago but it was never realised. Some major target performance specs are as follows:

• three isolated channels
• around 50W per channel
• 24V/3A output per channel
• lowest possible ripple at fastest response
• small size
• programmable via USB
• nice housing with minimalist user interface (2 plugs per channel, knob, button and small display

Once finished (deadline is end of January) this project will become open-source software and hardware.

My quadruple BDC driver for supports up to 4 brushed motors with encoders. Each motor is controlled by its individual closed loop and individual PID gain settings. Additionally, motor speed can also be individually addressed. Analog part of the driver is based on DRV8701P predriver and is controlled by STM32F4 microcontroller.

Light Emitting Dance shades – general purpose party accessory.

LED Shades v0.3

About this project

I believe many young adults like to party and with the rapidly growing EDM community a lot of people attend parties with electronic music. I am one of them and you can probably tell where I got the idea to make the LED shades. Projects like this one don’t just keep me occupied in my free time but are also designed to broaden my knowledge in electronics and programming.
