Nowadays, you probably would have to use discrete transistors such as MPSA42 to drive Nixie tubes from a 5V or 3.3V logic ouptut. If you were driving your displays in multiplexed mode, implementing the anode drives might be fun .....

74141 is a Nixie (0-9 symbol) decoder-driver with HV open collector outputs, the K155ID1 (Latin transliteration) is the Russian counterpart.

Re: Looking for a project
I have been away for a couple of days. I just came back and I am so impressed with all these suggestions everyone is making. I started replying to each suggestion individually and now I have just looked to see how many there are! Thanks. I will read carefully everything that people have said and get back to you - hopefully sooner rather than later with a status update.

Re: Looking for a project
Ed, also I found the Z668M tubes stunning. I think they are now either a Siemens line, or no longer manufactured , so quite expensive. I cloned the circuit of one with six tubes in around 2005. They are physically large , especially compared to the ex-Soviet clear glass types. Worth hunting down if for wow factor !

Re: Looking for a project
It's funny you should say that. I have a circuit I have been walking around holding for the last few days. I will try to find it. Is it possible somehow to attach a PLL to a super regenerative receiver? The thing I find about the Super Regens is that with a decent speaker it is actually possible to get something that is very nearly enjoyable to listen to. |

Re: Looking for a project
I am dreaming up a 3 valve high quality low powered AM Pantry transmitter using NOS TV valves. I am already into the early planning stages.
