The H-Bridge I built was originally too slow. I perfected it using smaller pull up/down resistors and tuning the transistor choice further, and it’s now giving very good performances. On this matter I highly recommend the Art of Electronics’ chapter on bipolar transistors under “2.2.2 Switching circuit examples” which explains […]

In my previous series about VFD filament driver, I built a power supply based on a few operational amplifiers and a transistors. I actually implemented this design in a fully fledged PCB: However, the method used is not perfect. I can still see some biasing issues proper to the […]
