This is a nifty idea.
mrm electronics fyi
With excellent Tone, I might add!
Save your dead tubes and make your own. You can power LEDs from the wall with a simple diode/resistor circuit.
would love to see how - at this point in life "gift giving" is shifting from tangible things to experiences, but sometimes a small token is still appropriate - hand wrought would improve it if it still looks good and functions well.
and who cant use a night-light?
Peace - Deeve
Get a couple of cheepo bulb-type nite lites and some tube sockets that have a hole through the center; the hole is where the LED goes. Only other parts are diodes, resistors, and caps. The half-wave version with a single LED is a bit more 'strobey' than the full-wave because the LED lights only on half the 60 Hz wave--60 flashes per second. The full-wave version operates in push-pull (the LEDs alternate)--120 flashes per second.
Use epoxy to bond the tube socket in and fit the parts into the nite lite body. Make sure to get the type of lite that has screws so it can be easily opened up. The bottoms of 9-pin tubes are clear glass, so the LED's light shines up into the tube. Try white or blue LEDs.
How about some Rock-n-Roll Tequila!
