Simple answer, don't use a transformer. There are plenty of step-up converter designs that use more commonly available inductors. If you where a power supply designer, then yes you would use the best piece of 'magnetics' (coils, transformers ...) you could get. For the pros, that means something custom. But for running a few small nixies, you don't need anything exotic. I have a few schematics in my Skydrive: https://skydrive.live.com/?cid=F9DB37B8211CE831 Its under Electronics Projects, in the 'Nixie Power Supply' sub- folder. If all you're running are a few IN-17s, then any of these will do. You're only looking at 6 to 10mA. Its a nice exercise, if you want to play with it. But if hankering to get your project up and running, and don't need the extra distraction, you can always buy one pre-made. There are plenty of them on eBay. Just search for nixie power supply The two at the lowest price come from Mr Taylor, a member here. Not only are they at the lowest price, but they also have the highest output, and are the most compact. You don't need that high of an output, but thats only reserve capacity. Think you and Bill Gates, in line at a 7-11. Both of you are buying a large Slurpee. You both pay the same, but Billy has the higher reserve capacity. Current (amps, milliamps, ..) is like money in the bank. Also his supply (Talyor's, not Bill Gates) starts working at ~3V in. To get the most out, the supply would like to see 12V to 16V in, but for your needs, at 3V, it may still deliver enough to power your project. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
