Re: [neonixie-l] Argon Piranha

Hi John, They did not light. The kit is running 170v across a 220k resistor. Interestingly, they did not light when held next to a plasma ball. - Bill On Saturday, June 13, 2020 at 9:35:06 AM UTC-4, jrehwin wrote: > > > I happen to have a few of the NHK GD412-200V spark gap tubes. > > >

John, I happen to have a few of the NHK GD412-200V spark gap tubes. I accidentally thought they were neon bulbs and installed them on the Wemos Nixie Clock kit from Ian at Nixieclock.biz (a great kit btw.) What voltage is needed to cause them to glow? Since these are 200v spark gaps, I am

Re: [neonixie-l] Argon Piranha

I also made such lamps. Please watch the video to the end. The video is my work, but the investor from VG ran out of money. https://www.youtube.com/watch?v=oFJ1hMNmE3A чт, 19 дек. 2019 г. в 21:13, Jon Jackson : > A9A shows as NEON on Mouser and Allied with a nominal lifetime of 25,000 > hours,

Re: [neonixie-l] Argon Piranha

A9A shows as NEON on Mouser and Allied with a nominal lifetime of 25,000 hours, so that cannot be argon. On Thu, Dec 19, 2019 at 10:53 AM 'John Rehwinkel' via neonixie-l < neonixie-l@googlegroups.com> wrote: > Where can you get the NE-2 style lamps? I can't even google them! > > > They're tough

> Where can you get the NE-2 style lamps? I can't even google them! They're tough to find. There was an AR-9 (K4A in the new numbering system), but I don't know of any vendors (Chicago Miniature (now VCC) used to make them as part #333). It shows a 50 hour life vs 25k for neon filled lamps.

Mouser.com or allied.com. Their new number is A9A. Allied.com has the better price in quantity. -joe On Thursday, December 19, 2019, Paul Andrews wrote: > Where can you get the NE-2 style lamps? I can't even google them! > > On Thursday, December 19, 2019 at 10:24:14 AM UTC-5, jrehwin wrote: >

Re: [neonixie-l] Argon Piranha

Thanks to you both! Jen I’ll put up a video soon; I’m still experimenting with optimal voltage and current levels, for best results You’re spot on, current draw is about 10-15mA, and the argon is noticeably less bright than the neon, even after adjusting current based on Dalibor’s recommendations

Re: [neonixie-l] Argon Piranha

Very cool! How much current does the argon tube require ? My recollection is that Argon radiates significantly less energy in the visible region compared to neon. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group
