- THIS MOVES A TON OF AIR. = pick-n-pull salvage - DEMO It squeals a bit a lowest speed because it's used and came off a high mileage wrecked Volvo. 100hz basic freq. Pulse input with 90% duty cycle spins fan at LOW speed. speed. Pulse input with 10% duty cycle spins fan at HIGH speed. Pulse input with 50% duty cycle spins fan at MEDIUM speed. So it's continuous variable from stopped to full speed and any speed in between.
Nice Job Anthony
sounds like a beast, could be really useful for the smaller sized radiators commonly used on vintage hotrods
Do you thick your stand alone pwm can stand under hood heat and survive? If not what would you suggest as a module?
I am writing arduino code this week and that will work fine in heat conditions.
How do you go about keeping the arduino alive in the harsh electronic environment of a car?
Arduino will be put in a watertight box and will be fine in extreme heat and cold.
How will you power it though? Wondering how you give it stable enough power and deal with voltage fluctuations?
Pic of your box when done?
Link for ebay $
huh? I got them fan from local pock-n-pull salvage yard on half price day. arduino nano on ebay for under $4.
