It can be even more dangerous to do so during rainy or  snowy weather conditions. Thanks to Designbuzz's DIY <a href="http://www.designbuzz.com/entry/solar-powered-weatherproof-bike-helmet/" target="_blank">guide</a>,  you can get your hands on one of these helmets that are sure to keep  you noticed, all while protecting your precious head from the weather.    Unlike other helmets equipped with LED lighting, this DIY <a href="http://www.tomsguide.com/us/DIY-Bicycle-Helmet-Solar-Power,news-13132.html#" target="_blank">[COLOR=blue !important][FONT=inherit !important][COLOR=blue !important][FONT=inherit !important]project[/FONT][/FONT][/COLOR][/COLOR]</a>  utilizes a solar panel and rechargeable batteries to make sure your  helmet remains fully charged throughout the night. Several bike rides in  the daytime will keep the helmet charged for the night, but there is  also support for regular AAA batteries in emergency situations.    If you happen to have a bicycle helmet laying around and are feeling  adventurous, check out the guide below. For more information on the  project along with a FAQ and tips, head on over to the full article over  at <a href="http://www.designbuzz.com/entry/solar-powered-weatherproof-bike-helmet/" target="_blank">Designbuzz</a>.    Time required: 4-5 hours working time. 24 hours for glue drying and another 24 hours for spray paint drying. Resources required 1. Multimeter 2. File 3. Soldering gun 4. Insulation tape 5. Solder and Flux 6. Circuit board 7. Helmet 8.

However, to purchase all other things you  may need up to 50 dollars. If you do not have tools, you can borrow  them from friends or buy them from local hardware <a href="http://www.tomsguide.com/us/DIY-Bicycle-Helmet-Solar-Power,news-13132.html#" target="_blank">[COLOR=blue !important][FONT=inherit !important][COLOR=blue !important][FONT=inherit !important]shop[/FONT][/FONT][/COLOR][/COLOR]</a>. Instructions STEP 1: LED Mounting If  you have a breadboard, then test your LED bulbs all together to check  whether it is working with 3 AAA batteries or it will need 4 of the  same. After that put shoe goo in the mounts. Place the mount, the vent  of helmet in such a way that it does not block the aeration. Solder the  wire on LEDs and put the wires inside via the air vent. Fix the mount on  the helmet and glue the LEDs on to the mount. You can decide the  arrangement of LEDs according to your need. STEP 2: Installing the solar panel For  installing the panel, you need to reinforce the leads of the solar  panel on the Black shoe goo and connect the leads with wire via  soldering. STEP 3: Fixing the black Velcro. Put  the fuzzy side of the Velcro outside with the inner side towards the  helmet. Take six pieces of Velcro and align it perpendicular to wire  leaving the panel. Mount few more Velcro on panel Velcro to give  strength and alignment. Fix the solar panel on the sticky side of Velcro  and place the whole arrangement on the top of the helmet. Press it fix  on the helmet. You can also use glue to give strength to the attachment.  The glue will also prevent water damage and leakage. STEP 4: Working the electrical connection Fix  the soft case on the Velcro and fix it on the helmet. Connect the wire  on to the battery holder and put shrink tubing on them. Once you have  soldered the wires, you need to connect the LEDs to the battery holder.  After, that panel needs to be connected to battery holder. Solder the  wires to connect panel with the battery holder. Put the shrink tubing on  the wire joints. Then cover the entire <a href="http://www.tomsguide.com/us/DIY-Bicycle-Helmet-Solar-Power,news-13132.html#" target="_blank">[COLOR=blue !important][FONT=inherit !important][COLOR=blue !important][FONT=inherit !important]wiring[/FONT][/FONT][/COLOR][/COLOR]</a>  with tape. Once the assembly is ready, you need to connect the switch  to the main power supply. Cover the assembly with shoe goo. Mount the  switch on the black shoe goo or you can use the super glue to connect  the switch on to the side of your helmet. Put on tubing on the wire. STEP 5: Finalizing the helmet Spray  paint on the entire assembly with black paint or the matching paint to  your helmet color. Therefore, that wire clutter, scratches or goo merges  with helmet. Once the painting is done then let it dry for 24 hours.  Put the batteries and let it stay one sunlight for 5 to 6 hours. Your  solar powered helmet is ready. <a href="http://www.tomsguide.com/us/DIY-Bicycle-Helmet-Solar-Power,news-13132.html" target="_blank">http://www.tomsguide.com/us/DIY-Bicycle-Helmet-Solar-Power,news-13132.html</a> </blockquote>
