Recently, i purchased a big lot of Philips ZM1000 Nixies, and needed a test PCB to test out if all was good – i got sockets for a number of the tubes, so i settled on making a PCB with the correct socket, so I easily can test them.

Being fond of the Arduino, i just thought, why not make it an Arduino shield – this way it’s a nice compact solution, powered by the USB-port, and no extra cables needed.

I earlier on aquired one of the real nice high voltage supplies, perfect for nixies from Taylor Electronics

So i made a single PCB that fits the small power supply module, a socket for a 74141 Nixie driver, and a socket for the ZM1000 tube.

I milled the PCB on our PCB milling machine in the local hackerspace where i frequent, Labitat

I did not mount all the headers on the finished PCB, since they are not in used. The use of stacking headers are a little waste, since there is no way I can mount anything on top of the Nixie PCB, but they make the PCB headers more mechanically stable, since they are soldered on on the bottom side of the PCB.

    Would you be willing to sell any of the zm1000 tubes? I’ve been looking for some and they are hard to find.

  2. Per Jensen Says:

    Sorry, no.
    I’m holding on to them for future projects.
    They come up on eBay from time to time – there even is some on eBay right now.

    Otherwise try writing on the “Neonixie-L”-mailinglist.

    Hi! I’m looking for ZM1000 socket, where did you find yours?

  4. Per Jensen Says:

    I bought them with the tubes. Look on eBay for them.

    Recently got my hands on a few of these tubes as well including SN7441AN chips, what are you using in your design to drive the tubes?



  6. Per Jensen Says:

    The driver is the 74141 and the high voltage supply is the Tayloredge 1363
