Headlamp - Used for BSA Electronics Merit Badge
thingiverse
This is a headlamp I designed to be used to complete the BSA Electronics Merit Badge. All you should need to complete the merit badge is included in the PowerPoint slides that are also included. It takes about 3 hours to finish all the requirements. You could also use this to teach anyone about basic circuit design using KCL and KVL. The structural components for the headlamp can be printed from any material. You will need to purchase a AAA battery holder/switch combination, pin cable, and some LEDs to complete the project. You can purchase them from adafruit.com (product #s 727, 3814, and 754), or you can get them from many other places. The Adafruit switch is in a convenient location with the design I submitted. It would really be better to use a printed circuit board to mount the LEDs, but if you follow the instructions in the Powerpoint file that is included, you can make the headlamp without needing access to a printed circuit board manufacturer.
