Most people won't really care about this item, but others might find it useful. It's sold as a wireless remote LED dimmer which supports 9-24V DC input / output 12V. It's actually just a PWM, means it can be used as a cheap speed controller for a servo or motor, and states it's rated up to 8A. Could be a good little gadget for remote control dimming of DIY LED lights, or remote control speed of DIY motorized sliders and dollies. Wonder how well it will work on my motorized Lazy Susan. Starts at about $6 dollars on eBay (click here).
