I returned from traveling to find all of the parts I need to complete my nixie counter project had been delivered. So, I connected the tube to my new Russian 74141 nixie driver clone, which really is a handy part, as it's hardly more than a set of high-voltage NPN transistors in a DIP package. Then, I hooked up a microcontroller, an ATtiny2313 to…control it. I picked the 2313 because of the hardware UART, and it has enough IO pins to drive the 74141, drive a couple of extra NPNs for the decimal point elements, do serial communication, and PWM the boost converter.
From here, I'll finish the project in three phases:
- A fully functional breadboard circuit, using the nixie power module I got from John Taylor.
- Same breadboard circuit, using PWM boost converter.
- PCB circuit and finished aluminum case.
Next up is the comms interface for (1) and the software to feed it my inbox count.
