If you ever used a commercial calorimeter you pretty much know how much trouble these rather expensive devices can put you through when it comes to getting proper support for them, so an independent developer set out on a quest to build an open-source calorimeter.
The device is called the
ColorHug and according to its developer, Richard Hughes, it's both faster and cheaper than proprietary hardware, while having a GPL bootloader, GPL firmware image and GPL
hardware schematics and PCBs.
Right now, the ColorHug is still under development, but its creator wants to build an initial batch of 50 units to test the firmware and sort out any other issues that may appear.
Before embarking on this road however, the open-source enthusiast needs some advanced orders for this initial batch of calorimeters so he won't get stuck with lots of stock and no one to sell it to.
With the 20% discount he is offering right now, the ColorHug costs only £48 ($76.5 or 56 EUR) plus postage and packaging, so if you want to do your part in promoting open-source solutions make sure to pre-order one. This will help us all in the end.
