BlinkM Coin Cell Battery Holder

thingiverse

Energize your BlinkM or BlinkM MinM smart LEDs using this snap-together coin cell holder and mount. Only minimal soldering (two solder dabs) is required. The design features holes for transforming the device into a pendant or adding extra diffusers over the BlinkM. Assembling the parts is straightforward: insert a 4-pos female header socket, feed in two short wire pieces, solder them to the pins on the header socket (these become battery terminals), bend the wires for good cell contact, insert coin cells, snap together the top piece, and place your BlinkM inside to enjoy its light display. To protect the back, apply a small gaffers tape over the terminals. While coin cells may not be rechargeable, this portable solution offers an excellent way to showcase BlinkMs. Replaceable CR2032 rechargeable cells are also available; use only one and fill the remaining space with spacers like pennies if needed.
