Eggcellent

It's not eggactly(The puns will stop over my dead body!!!) finished yet, I'll work on it more this weekend. I wish I had a jumbo sized one. (Note the red hue is artificial but close to how it looks, the flash on my camera completely rapes the glow of the egg).

(Edit: More info)
Basically what I was originally trying to do was have an egg flash while the alarm went off. My plan was to just hook it up to sync with the beep by splicing off the wires to the clock's speakers. This didn't work as is since the voltage coming out was too small, so I tried using transistors(I have no clue what type. I plugged some in till I got the desired behavior), which worked but was too dim. I ended up chaining the transistors together and came up with something extremely sensitive. So sensitive that just approaching it would set it off. So then I decided screw the alarm clock I'll just have it glow brighter the closer someone gets. Below is the very basic circuit I used, note I don't know if I have the transistors properly done in it(ECB and all that), but it gets the point across:


Well the weird thing is if the light source is inside the egg it stops working completely, which I don't know hardly anything about EM fields or whatever is involved to even hazard a guess as to why this is. The original picture is just an antenna in one egg and the light in another, which worked as expected(Getting near the unlit egg lit the other one).

Right now I have no clue what I'm doing with it, I'm trying to use spare parts I have to make an egg do something interesting, but I'm missing a lot of essential stuff(Timers, op-amps, etc). One thought was maybe make an EMI sensor, where the egg glows brighter the more there is....I'll just have to see if I can find another handfull of transistors to get it that sensitive.

WTF are you doing to those poor innocent eggs?
