If you haven't been to Cogwheelcircuitworks.com in a while, go check it out. Bob is working on a revision to his driver board that will allow it to power led backlights as well. This modification will work for both the IN-17 version of the clock as well as the larger B7971 version.
The TubeClockDB / Tube Clock Database is a collection of nixie clocks, vfd clocks, vacuum fluorescent clocks, crt clocks, scope clocks and oscilloscope clocks. We will feature just about anything: fully assembled clocks ready to purchase, kits, or even individual nixie tubes. If there is something that you think would make this a better resource, please contact us.
