Here is what I call the Snow De-Lite
I have been stuck at work for 48 hours because of the snow storm hitting Pennsylvania, Maryland and the rest of the Northeast. Luckily, I had some time to read the De-Lite article and I started digging around my junk pile at work. I found some IXYS IXFK73N30s from a bad motor control board and then searched for the remaining resistors, caps, and light bulbs. I found what I needed. Power supply is two 12 volt high current batteries in series for 24 volts. Source resistor is a 2 ohm 20 watt wire wound. Bulbs are four 40 watt tubular bulbs. Everything else is the same. Attached is a picture and it is a bit hacky, but it works. The build quality is not as nice as my Zen Lite, but hey for an hour's work...it took my mind off of the snow.
I also included a picture of the front of the hospital where I work.
Nelson, thank you for another fun project!
Tomorrow...hopefully home and begin digging out!

Who's going to show us a picture of an Afternoon De-Lite?
Picture of a couple sneaking out of the office in the afternoon for a private moment....at home listening to their De-Lite
...and of course making sweet music togetherNice!
two essentials:
1. The unobtanium transistor
yeah ! I have go the two types from 1) Mouser 2) Digikey
Going to upgrade currents and voltages asap and then will try the non cap version . In the meantime the sound is marvellous but want a more impressive powerful level .
Grazie !
