Thanks - yup I'm looking for a pretty fast dissolve. Probably less than 10 seconds. I'll note though that the substance will be a thin film, no more than 1/16th of an inch thick, though.

I like this idea too, thanks! So beeswax won't dissolve in alcohol/water but will in vegetable oil? Any idea on how quickly it dissolves?

Resin looks like it could fit the bill. It seems like you might be able to mold resin into a fairly flexible but solid material (i'm not sure this is the case because it doesn't explicitly say it on Wiki, but i assume you can). It also seems to be insoluble in water but mostly soluble in...

Thanks for your answer! Is there a particular kind of wax you had in mind? I feel like I had read somewhere that mothballs will dissolve in rubbing alcohol but not water...but i think those are poisonous, so it probably wouldn't meet criterion number (3).

It looks like there have been quite a few views of this thread (35+) but no responses. Maybe someone can explain the requirement above that's causing the most difficulty for folks and we can work our way around it? For example, if 1 and 2 are possible but not 3, please let me know that and...

Hello! I'm looking for a substance that can: (1) be turned into a flexible material (e.g., a flexible plastic), (2) is dissolveable in rubbing alcohol but not water (or blood), and (3) safe for a medical procedure ... And, if possible, preferably biodegradable... I know that's kind of a...

A fuse is a really good idea -- I was thinking about adding one. Do you know of any good fuses (digikey preferably) for this project? I'm definitely aware that if I use a metal enclosure I'll need to ground it -- I was wondering if I could use a plastic enclosure instead, or if that was a bad...

What about using a plastic box -- or is that a really bad idea?

I actually intend on connecting all the grounds and neutral together, so this might work out well. The hot is the only one i want to turn on and off independently among all the outlets with relays.

Oh crap, that should be 3.3, not 33. My bad--fixed. Did you mean you're -not- familiar with the ATMEGA168? Making sure I use proper wiring techniques when working with the mains is my concern, too. If you see anything wrong with my schematic, or just have any tips/tricks, please let me know!

Hi everyone! So these forums have been great help to me as I've gone through the beginning stages of my design process and begun choosing components for my project. Thus, I figured I'd enlist your help to look over my first rough design draft. A little about the project: The overall idea is to...

Ok great thanks!

Ah ok thanks! Do you know of any good enclosure/box that could fit four of those in a row in it and would still be easy to drill holes into ?

Thnx for the info!I'm actually trying to build a little project for stage lighting (for my band) where you'll be able to plug in up to four different color lights, and they'll each be independently be controlled (turned on / off) by a microcontroller...so this isn't for a home application. I'm...

What about regular duplex outlets like these (the double ones): http://media.photobucket.com/image/single%20electrical%20outlet/jwelectric/rec15and20.jpg ... can I send power to each one of those plugs independently, or is it like the GFI where one incoming set of hot/neutral controls the...
