Skating at night can be really dangerous. Other road users won’t see you and you can’t see the road you are riding on. That’s why I invented the Beamboarder. It’s a mobile head light that allows you to ride for up to two hours in absolute darkness with a sight of several meters. The LED and the rechargeable battery can easily be attached to your board on any ferromagnetic material. The Cree LED is a high power light source out of an array of several LEDs with the highest standard of light efficiency you can find actual on the market. Only minimum changes on the longboard truck have to be done. The construction of the lamp is possible with a small amount of money and equipment. Even it’s easy, there are several risks for you and other road users you have to keep in mind. The following instruction shall guide you through the experience I made and how you can build your own Beamboarder by yourself. Keep in mind that this product is still in early prototype status.
- 3.5’’ Hard Discs Drive with large capacity - SSDs will not work ;)
- Cree XLamp CXA1304 9V High Power LED - This is the magic
- Tensai TR-9.6V (9V-Block) 270 mAh Ni-Mh Rechargeable battery -The only battery I found yet that fits to the LED
- 9V battery clip with about 15 cm wires - Do not buy the cheapest one.
- Arctic Alumina Thermal Adhesive -The minimum quantity I could find is with 5g.
- Thick heat shrink tube with a diameter of about 3 cm
- LED optic like an old skate bearing or 3M bumpon
- Battery Charger for Ni-Mh
