Simple LED Flashlight

This simple LED flashlight is designed to teach people how to solder, use a 3D printer, and operate a laser cutter. I ordered all of the electronics components from Adafruit, but you could easily utilize any spare components 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 and assemble it with precision. - Create a custom button using your 3D printer's capabilities. - Laser cut a window out of 1/8 inch thick clear acrylic for optimal visibility. - Trim leads from LED, resistor, and battery holder components to ensure they fit neatly in the enclosure. - Solder the positive (red) lead from the battery holder to one end of the resistor with careful attention to detail. - Solder the other end of the resistor to one leg of the momentary button for a secure connection. - Note that the momentary button has four legs, arranged into two pairs of connected legs. When pressed, all four legs are connected seamlessly. - Solder the negative side (short leg) of the LED to the negative (black) lead from the battery holder with precision. - Insert the LED holder into the front hole of the enclosure for a smooth fit. - Securely attach the battery holder to the bottom of the enclosure using hot glue or epoxy, ensuring easy battery replacement. - Place the LED into the LED holder and position the button on the raised platform in the middle of the enclosure. The legs of the button should straddle the platform comfortably. - Position the 3D printed button in the square cutout in the acrylic window for a seamless fit. - Snap the window onto the enclosure with ease. - Insert batteries into the battery holder and enjoy your newly assembled LED flashlight!
