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!

Verrryyy cold!! Brrrrrr....
Clever way to while away the time... and from a broken motor control, you say. Got to love the DIYer.

Nice!

Regarding Afternoon De-Lite, I'd do it, but I need two essentials:
1. The unobtanium transistor
2. A spare afternoon 😀

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

Nice!

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 !
Bulbs are four 40 watt tubular bulbs.
Are those the same as aquarium light bulbs?

No, these are regular incandecent bulbs. They are used for some vertical sconce lighting. (Thanks to the maintenance department for letting me dig around.)
