This is something I experimentally made way back in 2007. I often prototype direct to an etched PCB, so sometimes some random errors slip in. Particularly when I do it late at night. In this case I made two errors. I put an extra dot in my domain name and I missed a track. Both easily fixed if I ever revisit this project again.
The idea of the color puck is simply to provide an illuminated highlight on a shelf or table. It has either two or three holders for AA style NiMh cells, and LEDs around its perimeter. When fitted with a set of batteries it will glow for a very long time.
I was considering making some of these in other shapes.

Three mistakes on the PCB, you also misspelled colour.
Maybe revisit the project and have it run off a authentic joule thief. You could use a 12V 70W LED panel protected by some glass or acrylic as a coaster that illuminates stuff from below. Depending on the transistor used, it can handle at last 40V open circuit voltage for the US type and 50V for the BC377 or 65V for the BC547. So the 12V are no problem. I tested it with a 10µH coil and a BC377 , which is not even ideal.
Make is into a water proof cube and stick in in a fish tank full of water. Then you can tell people that you have a
Cherenkov Radiation device in your fish tank.
hi clive did you ever revise this board using maybe super flux leds
project idea: add a solar panel, change battery to a small li-ion, make some kinda box or maybe encase it in resin?
lighted coaster!
been wanting do something like that for a few years now..
It would be fantastic to put random-color-changing (whatever) RGB LEDs in it. 😀
If it was reasonably priced i would definitely buy a few of them, coasters, bong coasters etc, (actually that would be really cool having a recessed center led so if you put your bong (or a glass of water lets say) it will illuminate the water inside!) (i would definitely buy multiple if that was the case) so let me know!
I'd buy this especially if you could change the colour with a switch and if it had a clip in mounting board so you could screw or stick it to anything
GLOWING table hockey puck!
That is a nice effect. Very sci-fi!
What about adding a little ldr/transistor light detector to it?
Why "color" puck and not "colour puck"?
would love to be able to buy this and maybe put 2 pin RGB leds in it! 😀
Why don't you use a string of WS2810 and a micro controller(Adafruit have a nice tutorial on it and a Arduino library) I know it won't be as power efficient but it will allow you to specify the RGB value and do different colors! even fades and stuff!(and who doesn't like a RGB led!?
<Shameless plug>
If you want the micro controller to be a WIFI connected ESP8266 Then check out my channel for my new series on them! 😛
