Remodelling of the GA250 gyro

Remodelling of the GA250 Gyro:

Update Oct. 23 2011: the photos below show the result of my first converson of a GA250 to a GA250 Gyromixer. In the meantime I do some things in a somewhat better way. A gallery of photos which presents the current remodeling of the hardware in much more detail can be found here: http://www.olliw.eu/2011/ga250-fpkoa...cher/#21072011

The first step consists of soldering the cables to the ISP pads and flash the Atmega8 with Haagens bootloader. This looked as follows:

Then these cables can permanently be removed, and two cables soldered to the pads which are connected to ports PB3 and PB5. In principle this would be it, but I did a bit more soldering to end up with a nice, fully wired device:

That's it for the hardware
