Glowy Things in Ice

by aaronstasis on Sun Dec 02, 2012 8:53 pm

Being the season (and living in Canada), I was thinking about embedding some glowy things in blocks of ice. The DA RGB LED Strips are listed as being 'waterpoorf', and the EL seems to be used in mix-use environments and may or may not be waterproof... any idea about whether I'll have success freezing either into blocks of solid ice? Both water with electricity & freezing stresses concern me a little (also I'm a noob), and before I trash some fancy glowy things, thought I'd look for advice. Other electronic components/power source would obviously be kept outside the ice. I was thinking about freezing a block of ice, wrapping it in glow, then freezing that block of ice inside another large block to seal the glowy bits below the surface.

With both the EL and the LED strips, the sheath is waterproof, but not sealed at the ends. You either need to seal the ends or keep them out of the ice. We do have end-caps for the strip: http://www.adafruit.com/products/774 We also carry Sugru, which is good for this purpose as well. https://www.adafruit.com/index.php?main ... ch&q=sugru

Expansion could be an issue, but if you pre-freeze the core as you suggest, it should minimize the stress on the strip or wire.

Sounds like a great project. Be sure to post photos when you finish!
