"TouchTimer" EggLight (valentine's gift)

\"TouchTimer\" EggLight (valentine\
«

Short description:
+High brightness microcontrolled LED light
+Touch Enabled (no buttons!) , the touch sensor will check it's inputs every 288ms to conserve power
+"Shutdown" TIMER : If the user holds the finger contacts for N seconds it will take N minutes for it to shutdown (or by touching it again )
+Estimated 60 days of battery life (15 min of use per day)



This is a Bedside Night Light I've built for my girlfriend:

+It had to be small
+Portable soft lighting for "stealth home navigation" at night
+It had to be COOL !

The Design:

ping-pong ball + generic_product_cap + capacitive_sensor_made_with_a_pic = EggLight !

Stuff needed :
- Ping-Pong ball
- Generic Product Cap
- PIC12F675 (any pic will do)
- A BC548 transistor (or similar)
- some standard resistor values: 100ohm , 1Kohm , 1Mohm
- 10000mcd led (When I have time I'll do the RGB version ;-)
- 2 CR2032 (button cell)

The initial design was supposed to be like the first picture... but an hiperbolic surface isn't quite easy to DIY =/
So I switched to the EggFormat
By placing the batteries on the lower side of the cap and sanding a piece of it it will stand-up straight

Hy First, great project ;-) You used the CCS compiler right? I'm just trying to rewrite the code to SDCC but I'm little bit hanging in the air because this is my first attemp to program a PIC. Does someone here have some example codes for SDCC just to see how to make the skeleton and using I/O Pins...???

AWESOME! Although, you get -1 man point for getting pushed around from your girlfriend, but +10 man points for actually having a girlfriend..... Man, it's Valentine's day and I don't have anyone... sigh.....
