Thank you all for your time. It is one of the socketed arduinos. Actually, this is my second one that was fried! As these chips aren't sold around here, I have to order them online. Ebay sellers from china happen to have the cheapest offers - got mine for $7 incl. shipping! The shipment usually takes a month to arrive. I would have bought more spare chips, but I wanted to make sure everything was alright before I do so, so I got only one. This time I will surely buy at least 3, and make sure I put some blocking diodes on the pins. Just in case so this kind of thing wouldn't happen again while prototyping.
Yeah I know about Siemens. Its just that I have this bad habbit writing ms as mS from college. You are actually the first ones to notice this and got confused, so I guess I should stop doing that. The idea to test the nixies controls with 5 volts is great. Its just that I will have a greater resistor on the anode (in my case any resistor at all), because it is then directly controlled. I can get a good brightnes and current that way, but it doesn't help me find out the resistors needed when multiplexing. But it will help me find out which of the 12 transistors burned out! I saw that schematic sometime, somewhere, don't know where anymore, so I tried to replicate the idea. And I can tell for sure that it used two NPN transistors, and none PNP for each tube. It's something like threeneuron's B design, just with an extra resistor. I'll play with that a little bit more. Also, what do you think about a clap-on clock? Is it really necessary, or can I get something like 10 years out of my nixies when multiplexed like this? And yeah, DO I, or do I NOT read the average current and the RMS voltage readings on the multimeter when measuring sine waves, pulses and such? Just so I know to properly calculate the peak current.
