It seems I'm often sitting around looking at my car and wondering what I can use my PICAXE chips for...
I thought it would be an interesting project to make all my windows go down automatically. Has anyone done this? Does anyone have plans, schematics, or ideas? I know there are aftermarket modules available but where's the fun in just buying something?
I looked around on this forum here and I learned a bit about motor drivers, H-bridges, and current sensing. There's even a guy who built a power window controller (for one window?) but there are no details on how and no one replied to his (1) post.
My driver's window has an auto-down feature where you tap the switch and the window goes down by itself. The circuit for that appears to be a few capacitors, a relay, and a small IC. I did notice that my windows don't have limit switches and the fuses don't blow every time a window reaches full up or down, so... there must be some sort of current limiting already in use. A spare motor drew about 1.6A with no load.
I'm not much of a cook but I can follow a recipe. Any help with the ingredients for this would be much appreciated.
*Not wanting to start a discussion about the legality/safety issue of automatic "up", I would like to have that as an option.
