Remote control your blinds


I was dredging my brain for interesting topics to cover and this vertical blind hack popped into my head. The page isn’t the prettiest, but it’s the hack that counts. The mechanism is constructed from PC board. A motor fitted with a ball chain drive gear pulls the chain in either direction. When the end of travel is reached, a micro-switch is triggered by the stand off that’s actuated by the chain. The motor is driven by a pair of relays that latch to form a simple direction control. When power is triggered on or off, the motor starts moving until the stop is triggered.
