Hi, I'm building a nixie clock "from scratch", designing the circuit (with great inspiration from other projects) and the PCB etc. Just for my own entertainment, not for selling or anything. I'm a hobbyist, not a professional :)
I want to have the power supply on the board, and was inspired by threeneuron's high voltage supply, which can be seen here: https://threeneurons.wordpress.com/nixie-power-supply/hv-supply-kit/ My problem is that I can't source the inductor L1 with the correct combination of *100uH* and *1.4A.* The closest I can get are: 1. 68µH / *1.4A* 2. 220µH / *1.4A* 3. *100µH* / 1.0A 4. *100µH* / 1.6A Now my question is, would I be able to use one of the four above mentioned inductors, without switching other parts? On the page linked above it says that you can increase the output power of the PSU by using an higher current inductor, but it also says that it's necessary to change some other parts like resistors and a capacitor. My thoughts so far: 1. I could go with inductor #4 and not change other parts, because I know I won't ever get over 3 watts total (but I'm not sure if this is safe or not) 2. Go with inductor #3, not changing other parts, knowing that I won't use up the current capacity (but again, is that really safe?) 3. Use inductor #1 or #2 — but again my lack of knowledge plays in, as I have no idea how significant the 100µH is, and would would happen if you increased/decreased it. I know I can probably get exactly the correct inductor from the right supplier, but I have to stick with a few who don't charge an arm and a leg for shipping (to my country), whilst still selling in low quantities. Also, I'm hoping to learn something here, by not simply throwing money at the problem! Any help is much appreciated! -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
