Yup I am aware that the voltage requirements are high and current a lot lower than standard Nixie type tubes and as you correctly say the circuit above will not do that. Hence the tippler comment I made in the original post. Leaning now towards the 2nd circuit now by Jan Rychter .. it is well

Dekatrons require substantially higher voltage than nixies; I'm running my A101 at almost 500V (datasheet says 450v). I use a voltage tripler from the 120Vrms line (US). Higher voltage is fine for nixies and dekatrons; you just need to have more anode-resistance (or equivalent) to keep the curre

Hi David, I hope I can help you but I only use Altium Designer for all my works, any other problems please let me know. Thanks. Yan. 在 2018年1月11日星期四 UTC+8上午12:18:18,w4smt写道: > > Hi! New to the group. > > Has anyone done an Eagle library for the NCH8200HV PS module? If not, I'll > roll my own. >

There are some nice photos in the auction showing the insides, I've never seen the insides of this clock before so that was a nice extra! /Martin -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group and stop receiving e

I don't like the 7 digit idea anyway, that 10th's tube just looks frantic to me. I actually prefer 4 digit clocks. In this case I think 6 would look fine. I'll start shopping for an appropriate clock board. Normally I'd roll my own, but this seems more like a packaging exercise than a technical

I'm thinking a Longines meets Steampunk clone would be cool here. A similar case to house any one of the now widely available IN-12 ebay nixie clock kits could be constructed from various brass fittings, tubing, and general hardware store bits and pieces. It would clearly only draw inspiration f

Hi all, Looking at open source power supply designs. The one below has been kindly made open source. https://vfdclock.jimdo.com/2015/07/18/openhardware-10w-mc34063-based-high-voltage-power-supply-module-high-efficiency-small-size/ I like because it already has the eagle files, so I am guessing
