Jason von Nieda’s vacuum tube clock based on our Ice Tube Clock kit!. Design files and build information available at http://www.vonnieda.org/tc18
I’ll give you $10 if you try to go through the airport with that.
Just wanted to drop a line and let you know that I am now selling a single one of these clocks. It will be the only one sold. It’s up for auction on eBay at http://goo.gl/Nl7Q
