It’s been a while since I did any hobby stuff, but with my Black Friday order coming in I have a new project! I’m getting on the translucent lighting train! I had planned to try this for the Wyrd Winter painting contest, but the cat is to far out of the bag and to many other people are doing it to make a big splash, so you get on time posts instead. 🙂
Here’s the starting point for the project, some electronics.
That is:
- 2 3V button cell batteries, with holders for easy replacement.
- 1 tiny little switch
- 1 1/4W 180Ohm resistor
- 1 3.6V 20mA “super bright” LED
- some thin wire
I had thought to use the PoweredPlay solution, but after looking at the price including international shipping (no ocean to cross, guys…) I decided, with some help to do my own thing. Turns out there are some knowledgeable people in CHOP!, so they helped me re-figure out the mathematics required to make it all go. (Last time I looked at any of these formulas was grade 12…)
Next post – figuring out how the hell to get the wires into the Ice Golem!

I’ll have to give it a go sometime, but I admit to still having some PTSD from my 9th grade electronics class, where I electrocuted myself badly and ended up coming to about 3-4 feet from where I was previously standing…

It was a physics class that studied the formulas – I had to learn about soldering and such from my father, but I didn’t learn all that well. 🙂
Actually, did some soldering this morning and it went pretty nice! I’ll have that stuff up in a couple days.
