I thought its use was limited to that. This site uses Akismet to reduce spam. About the best thing you can do with a disposable camera is take it too bits and then throw the bits away as they cannot take decent photos with any of them Regards Adrian. I added an appropriate resistor for my Nixies 47K , realigned the battery holder originally perpendicular to the board , shorted the trigger switch and installed a slide switch on the former cap charge switch. This will enable it to self-discharge in a controlled manner. Add a Comment Sign in to comment. Make sure the object you use to discharge with has an insulated handle, and only use one hand to minimize risk of electricity flowing across your chest.

Be careful, as we said before, this project deals with high voltage. Never did that again: You can’t break even, except on a very cold day. I clocked mine, at Kohms, the circuit went from full power about V to a more reasonable 20V in about a minute. I don’t think very much I’ll check. This site uses Akismet to reduce spam.

Nixie Tube powered from a disposable camera
Yesterday afternoon I was bored, so I thought I’d try some stuff with them. This can be done by touching both wires cajera out of the bottom of the capacitor with a screwdriver or other metal object. Email required Address never made public. I ran the wires out of the rear viewfinder window, so I had to poke a little piece of plastic out of the window.
That’s the simple explanation. Hello- I tested that with a non-rechargable alkaline battery. I thought its use was limited to that. You can tubf any resistance over 50Kohms, but the lower the resistance, the faster the circuit will decrease to a safe voltage. They come in glass cylinders Hence tubes and have one anode and several cathodes, each of which is shaped into a digit to be displayed.

I also recommend wearing safety goggles, because if the capacitor is charged, sparks will fly, and you don’t want one of those sparks in your eye. They run at several hundred volts, and draw about 2mA of current. Slightly OT, but if you watch the movie “Monsters Inc”.
I’m driving them at V. The tubes are supposed to draw about 1mA Notice the capacitor has a stripe on it. The black wire will connect to the lead beneath the stripe, and the red wire will connect to the other lead.
This is brilliant — the HV is the usual problem with Nixie projects, as you either have to line power them dangerous or find an isolation transformer not too common nowadays. I will post a pictorial description of how I took mine apart, but know that not all cameras are alike. Now I needed a way to drive them. Solder a resistor across the leads of the capacitor. Assuming the conversion from 1.
Also, this ccamera is nisie one of the more dangerous steps, because you do not know if the capacitor is charged currently.
You could use an inexpensive Nixie tube. Disposable cameras are quite cheap, and include circuitry that produces very high voltages. You can see two implementations of this idea already on Flickr. Sorry for not showing pictures of the calibration process, but this circuit blew out my multimeter when I accidentally created a short circuit.
Exercise caution throughout the following steps to avoid burns. Some of the other numbers, like 0, have a forest of thin support wires in front jixie them that cast shadows.
