LED Light Ring by 3D Central

简介

Motivation: I constantly find myself in need of a small amount of light at will, and the cell phone doesn't always cut it. My goal is to build a small but powerful flashlight ring. Details: I've tried two switch mechanisms so far. The first one had the head slide laterally, perpendicular to the finger, but it wasn't quite comfortable. This present model slides instead forward and backward. This also is not ideal.. it requires both hands to turn on and off, and the top is prone to falling off. I think the next version will try to have a twisting activation instead. Software: Model was designed in openscadpy (first project, sorry for the poor state of the code): github.com/hmeyer/openscadpy Hardware: Model was printed on an up! printer ( pp3dp.com ) My intent is for this product to be Open Hardware, under the TAPR OHL: tapr.org/TAPR_Open_Hardware_License_v1.0.txt Instructions Tools: Up! 3D printer, or equivalent support removal hand tools wire cutters soldering equipment Bill of Materials: (1) ring base, printed (1) ring head, printed (2) coin cell battery, http://www.sparkfun.com/products/337 (1) 1 SPDT slide switch, http://www.sparkfun.com/products/9609 (1) triangular proto board, http://www.sparkfun.com/products/8887 (3) bright LEDs (3+) extra lengths of wire Assembly Instructions: Print both parts. The size of the ring can be changed in the openscadpy file, but you might have to print a few different sizes to see what fits. Be careful though.. I've definitely had a few too…
