More Power To You! In this video I get into the basics of high voltage power supply design with a heavy 175VDC powerhouse I call "Big Iron". I get into some power supply basics and show how you can make a custom high voltage supply yourself with plenty of Umph to drive whatever you want. Enjoy!

    Nice lighting on this episode.

    merhaba nasılsın 🙏

    I had no idea about ionization. Wow 🙌

    I'm way late on this video, but maybe this'll help someone even later than me: there's a company called Antek that still manufactures transformers that're perfect for exactly this. Their AS-1T150 has 2x 150V windings and 2x 6.3 volt windings for $35. They've got a smaller one rated at half the power that would probably work well too! Not associated with them in any kind of way and feel like kind of a shill for mentioning them specifically, but they really saved me from waiting around for the right kinda transformer to pop up on eBay. Hopefully this'd be useful to someone else too.

    Has anyone ever come across or know of any machine that would have had a output display of Nixie tubes arranged in a grid pattern using both letters and numbers ?

    I love the explanation about the blue LEDs. Would an infrared LED work if you don't want to see any blue or otherwise visible LED light?

    What I used for driving a nixie tube or two, I used a disposable camera flash system. I connected the nixie tube to the 300v output and used a 22k resistor. I work fine, really, but the voltage would slowly go down over time with more than 2 nixie tubes.

    Looks like something I need for my project. But I have a question, I want to add a dimmer, go from 100% to 10% brightness on my nixies. Either with a photoresistor or do it manually with a pot. Is there a way I can do that?

    I witch I had a teacher like you.

    I just built mine without a transformer and an old school voltage doubler. I will use your design next time I build a nixie project, the mains bite hard!
