This simple LED flashlight is designed to teach people how to solder, use a 3D printer, and use a laser cutter. I ordered all of the electronics components from Adafruit, but you could use any components you have lying around. Part List: - https://www.adafruit.com/product/783 - Battery holders - https://www.adafruit.com/product/754 - 25 pack of LEDs - https://www.adafruit.com/product/2174 - 5 pack of LED Holders - https://www.adafruit.com/product/654 - Batteries - https://www.adafruit.com/product/2780 - 25 pack of resistors - https://www.adafruit.com/product/367 - 20 pack of buttons - Sheet of 1/8 inch clear acrylic Instructions: - 3D print the enclosure - 3D print the button - Laser cut the window out of 1/8 inch thick clear acrylic - Trim leads from LED, resistor, and battery holder so that they fit in the enclosure. - Solder positive (red) lead from battery holder to one end of the resistor. - Solder other end of the resistor to one leg of the momentary button. - Solder the other end of the momentary button to the positive (long leg) side of the LED. - Note: The momentary button has four legs. The legs are arranged into two pairs of connected legs. When you press the button, all four legs are connected. - Solder the negative side (short leg) of the LED to the negative (black) lead from the battery holder. - Insert the LED holder into the front hole of the enclosure. - Hot glue or epoxy the battery holder to the bottom of the enclosure so that you can easily change the batteries. - Push the LED into the LED holder and place the button on the raised platform in the middle of the enclosure. The legs of the button should straddle the platform. - Place the 3D printed button in the square cutout in the acrylic window. - Snap the window onto the enclosure. - Put batteries in the battery holder and enjoy!
