It's been a long time since I was active here- life has been keeping me busy. I've been trying to make sure these files stay available. Due to Google's security changes, the old links were disabled and I have tried to make sure to update with current links that work. I do not have any time to try to support this project but I wish you all the best in your builds. I think the weakest link is the DC-DC converter, which was my first go with high frequency circuits. There may be off-the-shelf products that would work better than my home-made attempt. I challenge anyone to test some of the units you can get on mouser/etc.
