Disposable Camera Nixie Tube Driver

Step 6 Create the circuit and use.

Now, wire up the circuit for the nixie tube. Put the potentiometer in between one of the leads and the nixie tube, and adjust as needed. With my IN-12A tubes, 200Kohms pass about .3 mA, which is enough to illuminate the tubes, but is not very bright. Experiment with your own tubes (use the multimeter here). Sorry for not showing pictures of the calibration process, but this circuit blew out my multimeter when I accidentally created a short circuit. Like I said, be careful.

When the camera is on, the high voltage is present, so please exercise caution when using this.
