Re: [neonixie-l] What is this HV gadget?

With a single probe. My best guess just an oudin coil Used often times on argon, krypton and HeNe lasers. If tube lights up it is still gas intact otherwise it’s open to air But that is a guess Sent from my iPad >> On Jun 24, 2020, at 4:32 PM, Mac Doktor wrote: > https://www.ebay.com/itm/

I assume it's high-voltage+high-frequency intended to ionize gas in a tube being tested for leaks. More convenient than lugging your plasma globe around at swap meets, etc. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this

Thanks a Lot! the main reason of this is learning always, love electronics, so I will take a really good look to the link you attached. Let´s see If I find a way to change the design to it works. Thanks a lot I will tell you How is going on El mié., 24 jun. 2020 a las 15:04, Kevin A. () escrib

sanchez, have a look at these articles by rohm semiconductor on DC-DC converter layout: https://techweb.rohm.com/knowledge/dcdc/dcdc_pwm/dcdc_pwm03/2734 this is quite a handy guide on how to optimize the layout of your board. since you are also using an LT part, I would also highly recommend usi

"Yes!  I would try that, the thing is that if I put those values, Ill get 350V 1,2mA as the datasheet says. That´s why I made this calculations : If I want to get a Vout of 180V for supply a Nixie tube, I need to put a R1 =47K and R2 = 300. that`s Why I putted those! " You need to look at the cu

Where is D4 in your circuit? It should be between the transformer pin connected to SW and the transformer pin connected to ground. On Wednesday, June 24, 2020 at 9:06:07 AM UTC-4, MrThe50sanchez wrote: > > Hello ! > > Yes, I used the components that the Datasheet says, I got it from here: > >

Hello ! Yes, I used the components that the Datasheet says, I got it from here: The thing is, that a Triple Voltage Circuit uses electrolitic capacitors, this is not the same configuration as a voltage triple circuit, but, Can It be that the capacitors I added are not electrolitic? I just p

Re: [neonixie-l] HELP WITH DC-DC BOOSTER CONVERTER

So if you really want to make this project work, then it's probably best you start with a fresh layout. The PCB layout that you started with needs a lot of work. Believe me, I made the same mistakes when I first started designing high voltage power supplies. Take a look this article I wrote which

Re: [neonixie-l] HELP WITH DC-DC BOOSTER CONVERTER

Read the layout recommendations in the LT1308A datasheet. You will need to adapt it to this configuration. What is the voltage rating of the 47k resistor? What are the voltage ratings of the 10nF capacitors? What is the voltage rating of BAV21W? What is the saturation current of the transformer
