Light up your ride with an LED mohawk

[Garrett Birkel's] weekly ride usually features some pretty wild costumes. He wanted something to step up his own look so he make this LED mohawk bike helmet. He had an LED strip to start with and found a way to use acrylic and clear plastic tubing to fold the lights into the appropriate shape. From there he designed a PCB for some DC-DC converters to provide regulated power. The juice comes from Lithium Iron-Phosphate cells, the same kind we saw in the electric bike assist battery a few days ago. We find it a bit wild that you can pick out the PWM of the LEDs in the lens effect of that photograph.
