IN-12A/B Nixie Tube Breakout Board

Breadboard (0.1" header pin) adapter for IN-12A/B nixie tubes

Public Chat
Similar projects worth following
Nixie tubes are notoriously difficult to use with a breadboard/protoboard. This makes prototyping nixie displays, clocks and counters very difficult. This project is a breakout board with integrated current limiting resistor that aims to reduce the difficulties inherent in prototyping with nixie tubes.

The kit is now available for sale on eBay and Tindie!

  • 12 × Nixie Tube Pins For the nixie tube, obviously
  • 15 × 0.1" Header Pins For resistor bypass jumper and breadboard connection
  • 1 × 15k Ohm Resistor Current limiting resistor
  • 1 × 0.1" Header Jumper For bypassing the current limiting resistor
  • 1 × PCB Probably self-explanatory

  • Minor design change & more stock coming!

    I've received a few orders at this point so my stock is running a little low - I've just ordered all the bits and pieces to make 50 more kits, and I'll place a update when everything has arrived and they're ready to be ordered! I'm not sure how eBay/Tindie handle backordering, so I wouldn't suggest anyone try to place any large orders or anything.

    Since I've ordered more parts, I made a slight change to the board design. I simply added my website URL and nickname to the silkscreen so they're identifiable as my boards. Can't wait to get everything and start sending out more boards!

  • The boards work!

    I received the newly redesigned boards and they work! I've also received the extra nixie pins that I need. As of now, the project is for sale as a kit on eBay and Tindie. Check out the project links for those once the Tindie product is approved for sale!

  • PCB Mistakes

    Oops...

    I got the PCBs designed in a single evening and quickly sent them off to China for manufacture. They've arrived, and turns out there's a bit of a problem: I'm a dingus.

    The first problem is that one of the pins for the nixie tube was never actually routed to its corresponding header pin. So that digit doesn't work at all.

    The second problem is that I put the footprint for the nixie tube upside down. So in order for the board to work, it has to be placed upside down. Not very convenient or aesthetically pleasing.

    So I've fixed the board and sent the order off to be manufactured.

    Use a Nixie tube as a guide for installing the pins

    Place the Nixie tube pins onto the Nixie tube itself, this will allow them to be soldered into the circuit board much more easily. Don't slide the pins fully onto the Nixie tube, make sure they're just on enough to be held in place. If you slide them on completely, you might accidentally solder the pins to the Nixie tube itself.

    Solder the Nixie pins in place

    Insert the Nixie tube with the pins into the circuit board. Solder the pins in place. 

  • 3
    Snip excess pin length

    After the pins have been soldered in place, snip away excess pin length from the back side of the board.
