Open-source hardware project hosting is my passion. I spend most of my free time building neat gadgets or planning what I'll build next. I love building things, and I want to make Open Hardware Hub a place that inspires others to build, ...

You may have already noticed the red boxes that say "Support Open Source Hardware". These are part of our push to make open source hardware more accesible. We will be taking note of which projects generate the most interest. Then we'll work out a deal with the projec...

- NameMood light coaster

- What to do with old AA batteries? Throw them away with still some juice in them? No! Get a small and pretty efficient boost-converter module and suck them dry completely. Depending on the remaining charge, you may still get a couple of minutes or even hours out of them. Throw in a couple of funk...
- NameRGB LED RING V2
- Bymadworm
- I've updated an old design of an 8-RGB-LED ring with dedicated constant current LED drivers and better firmware implementing Binary Code Modulation (BCM), which provides 6-bit depth per color and low cpu utilization and individual control of the LEDs with double buffering. Oh, and it's darn bright!
- NameMonitor backlight
- Bymadworm
- This is a very simple project, as it mainly consists of using existing and otherwise unused prototype boards (see 'A lamp for nerds'), a little bit of creative drawing with Inkscape and sending the design files off to Ponoko for laser cutting. It's a good example of repurposing / upcycling pro...
- NameA lamp for nerds
- Bymadworm
- Incandescent lamps are out. I frankly can't afford wasting money by throwing 95% of the energy away. Fluorescent lamps contain mercury and the ones I had started to show signs of age (you know, the kind of light that makes places appear darker instead of brighter). Now what to do? Use LEDs of ...
- NameZombie Meerkat
- Bymadworm
- This is a 'Halloween-ated' xmas meerkat lawn ornament. That does sound much better than 'RGB LED blinking toy' - methinks. The time-lapse video runs at 24x speed.
- NameOpenbench logic sniffer pull-up/down wing
- Bymadworm
- Floating inputs are nasty, as you'll get erratic data. Something you don't want to see on your screen, it only adds confusion and simply doesn't look nice. And if you monitor many channels, your eye might slip and end up on one that shows 'crap'. Of course you will only find out about that mishap...
