Here's another nixie clock on eBay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150511570592
This particular model shows up from time to time. It was one of the few nixie clocks actually made for the consumer market, back when nixies where still produced. There is no circuitry, other than a rectifier, and the anode resistors. The cathodes are driven by mechanical switch contacts that are attached to plastic gears. Gear train driven by a small AC motor. Nixies were a natural choice, since that means the AC line voltage could be used almost directly. Only a simple rectifier (1N4003) is needed. Remember 120VAC, is the RMS value. The AC sinewaves peak at +165V, & -165V. The rectifier just makes sure the nixies see the +165V only. Just about the right strike voltage. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To post to this group, send an email to [email protected].
