6 LED display with 3 output pins. ASM code and video link attached. The video should play with realplayer. It should also fit on a 10F200 with minor modification.
I'm going to make a tiny PCB and use 0402 surface mount LEDs (0.5mm X 1mm).
The display part will probably be 5mm X 1mm...

I have built a table to follow the sun through 15 degrees of arc. Using a stepper to change the angle.
Man was it pretty...pretty inefficient.
So, I am thinking of using two gallon jugs at opposite ends of the table connected by a small water pump. The water could be transfered from one...

After a very educational thread with Sgt.Wookie, I have finalized my plan for the solar part of my rooftop unit.
For generation 1: (Overview)
Two 36 volt panels wired in parallel on a balance board (used to tilt the array to follow the sun) with a center fulcrum, using ball-barrings for...
I am awaiting my order for 108 solar cells.
The project for the DC only living space will be partial solar, partial wind.
I have started my calculations for the battery bank and have decided to stay with 6 - 8v DeepCycle batteries. The 8volts have a .11" thick plate size which is very...
I have found a heat pump that runs on DC for home use. Pretty interesting. Uses PWM for varying the compressor speed. They also offer an air-conditioner only version that I will be purchasing. The house currently has natural gas for heat that will have to do for a while. Ultimately solar...
