LM317 voltage regulator. The voltage is variable from 1.2 to 37VDC. Use the potentiometer for an exact adjustment....
Your diagram shows the PNP transistor, with the 2N3904 label. But 2N3904 is an NPN part. Your are probably using 2N3906, right?
That's all right, I don't need such a great precision of 0-12V. The power supply does not provide the exact 12 V anyway (on my PSU it's 11.35V)....
Thanks to everyone! Yes, I guess I will use the LM317 to regulate the 12V, and put a voltmeter to show the regulated voltage level. This way, I...
I have an AT power supply, which I want to convert to the lab power supply. I wish to make a variable 12 volts output, which I could regulate with...
You can also try some big high-power transistors, like those used in the TVs. They work with the high voltage, and might be able to handle the big...
Well, the NL-840 types are pretty inexpensive, and the digits there have a height of 15 mm. You can also use the VFD tubes, which are slightly...
Turbokeu: thanks for the circuit schematics. I might also try the voltage doubler/tripler circuit (capacitor+diode). Mine nixies probably don't...
Turbokeu: it's 300V because of the 12V - 240V transformer plus the rectified AC. Of course, the anode resistors lower that voltage. Probably, the...
About a year ago I found this nixie clock gallery http://www.electricstuff.co.uk/nixiegallery.html . Having looked at this, I decided to build...
TO bigal: OK, as I see in your graph, the ground is at 0 V while live wire is switching from 240V to -240V. I understand what goes on when the...
Hi, everybody, Can anyone tell me how the AC current works? I know that it uses two wires, hot and neutral, and, sometimes, the third one, ground...
