Looking for some input on this functional prototype I developed with some colleagues at a nearby college.
I am not a big fan of the colors; my colleagues chose them.
Quick description: This is a functioning bicycle headlight, which has a removable clip built into the bottom. The fan charges an internal lithium-ion battery, which in turn powers three ultra-bright LEDs. When the fan is spinning fast enough to charge the battery, the LEDs light up green, as a visual indicator of the charging process.
I designed this device to answer a need. Many cyclists have chosen their preferred mode of transportation for its environmental impact, or rather, the lack thereof. After speaking to a few cyclists about what they would like in a headlight, many told me that they buy rechargeable AA’s to power their headlights. While this is a step forward, it still leaves some problems. Rechargeables do lose effectiveness over time, until they no longer hold a charge. Also, a cyclist may be out at night when the batteries fail, and may have no light until they return home to charge their batteries. Additionally, having an internal rechargeable battery cuts down on cost and increases durability, since it requires no battery door.
Apologies for the photos, I know they’re not the best quality.
