Mini Lightsaber remix of Matchstick flashlight

thingiverse

Alternate enclosure for Prospect3DLab's Matchstick flashllight. I added a switch between the positive lead of the capacitor and the LED driver. Switch is part number JS202011CQN https://www.digikey.com/products/en?keywords=JS202011CQN Note: The 5252F LED driver has a minimum operating input voltage of about .9v, so the capacitor must be charged to at least 0.9v before the driver will turn on. You can temporarily attach a 1.5v battery if you want to avoid the cranking necessary to achieve this initial minimum voltage. With a 220uH inductor, you get about one and a half minutes of light from 50 full revolutions of the knob.
