Re: [neonixie-l] Useful tool on eBay...

Two months have passed and I haven't yet gotten my hands on a laptop CFL driver. Still, I would like to have a battery operated "wireless" Nixie tester for flea markets like the Masonlite device. During my electronics shopping wanderings these circuits came out: 5 V to 400 kV booster:

Nice! How would three or four STTH1R06 HV rectifiers work instead of two of the 800V or 1KV versions, just as well or would other problems arise? /Martin On Monday, 9 November 2015 00:48:52 UTC+1, taylorjpt wrote: > > Load testing is done and the transient performance is right on target >

3 would work just fine at 600x3=1800V vs 800x2=1600. I will switch to the 1KV parts since I already have PWBs. The forward bias efficiency impact will be minimal for two vs three diodes as the forard voltage at these low currents is so much smaller than the output voltage. It may even be a

Works on nixies, fluorescent bulbs, neon signs. On Sunday, November 8, 2015 at 2:31:12 PM UTC-6, charles wrote: > > On 15-11-08 01:23 PM, Paolo Cravero wrote: > > Two months have passed and I haven't yet gotten my hands on a laptop CFL > > driver. Still, I would like to have a battery operated

Thank you for the answer! I realise I need better probes for my scope to make the measurement you did in the second scope picture, I only have standard probes that aren't rated for those pulse voltages. Where did you hook up the probe to show that trace? /Martin On Monday, 9 November 2015
