Light Tree Chip
Posted: Fri Jan 28, 2011 8:54 am
I have some left-over light tree chips from last production run. $10 each, or 3 for $20. This is the heart of our best selling Pinewood accessory. http://www.newdirections.ws/lighttree.htm It is 8 pin 12F508. Add capacitor and battery to pins 1 and 8. Add a red, 2 yellows, and a green to pins 3, 5, 6, 7 respectively. You don't even need limiting resistors, since the chip self-limits. A momentary low on pin 4 starts the count down. How simple does it get? Of course to drive brighter LED arrays, you need to put some P channel transistors in to drive each color. It comes with a schematic. By purchasing it, you agree to not use it to compete commercially with me.
