Lots has happened. Yesterday evening, the software has reached the alfa testing stage. You can find the source in Github. (You can use the visualizer that Martin Sedlák made to run it on your PC while you are waiting for your own Gigatron.)
The assembly videos are now available on YouTube. It is a series, in which I go through all the steps to build a Gigatron. These steps are also explained in detail in the assembly manual that comes with the kit.
At the Hacker Hotel conference, I talked about the Gigatron and people were excited about it! We are excited too, as we are reaching the point where we can actually sell a batch of Gigatron kits. If you want to be informed, subscribe to our mailing list.
