Below there is a list of projects i did or still do develop in my spare time. Surprisingly - between many projects I've never managed to close, there are some i actually did complete :)

SPIN Edit (bitmap => radial coordinates converter)

Program evolved as integral part of SPIN project. It is used to convert input image (bmp format) to it's equivalent in radial form (either text or plain binary). Binary files are quite specific, and reusing theese may not be straightforward, but you can easily use text files in your persistence of vision projects.

Bike persistance of vision display (POV) - SPIN v2.0

LEDs were my fetish since I've managed to light first of them up, using 51 uc. This project is the result of this fascination.

Single SPIN unit is built of two boards:

  • each of the two boards has 32 LEDs on each side
  • both boards are equipped with single AA battery socket

SPIN can hold up to 16 images (32x256 radial pixels) which can be edited by user. It displays images only if bike is moving fast enough to let ti display persistent images (so it does not consume energy thoughtlessly).

LiPo charger with balancer

Long, long time ago, when I began to loose my mind and money for RC helis, I came across Lithium-polymer batteries for the first time. My LiPo charger was... let's say "not perfect", so I decided to make something that will suit my needs and satisfy my will of creation - my own LiPo charger with integrated balancer.
