Building a light bike that goes beyond the flashlight taped to the handlebars. This light is activated by a pressure switch, so turn it is as easy as touching the wheel. A halogen bulb is used for extra light, so that any danger on the road in full view.
Things You’ll Need:
- Halogen bulb with built reflector
- Pressure switch (see links to source) tomato paste can
- Smooth end can opener
- Cyanoacrylate glue (like super glue or crazy glue)
- Watch crystal
- Extension spring
- Wire cutter
- File drill
- Volt Batteries
Show More Instructions:
Remove both ends of canned tomato paste with a smooth edge can opener. Clean box, remove the label and drill a hole in one end capsn. Make sure the diameter of the drill used is smaller than in spring, but large enough speaker wire to fit. Discard the other end cap. Related items: dirt bike headlight without battery.
Attach the switch pressure the handle of a bicycle using a zip tie. Insert the key to where your fingers rest, not when the cyclist will support their weight. No switch position of the path of the other controls. Be careful not to attach a zip tie over pressure-sensitive part of the switch or the battery will drain and no light will turn off.
Use cyanoacrylate adhesive glue crystal clock over the front of the halogen bulb. Plastic will not work because it will melt. Other adhesives can be used (such as fever JB weld), but must be able to withstand the intense heat. Using a knife wire cut curved edges off the spring and use the file to take any sharp points off the edges. Weld spring of one of the terminals of the halogen bulb and make sure that it will hold tight when it cools.
Strip wire the switch for pressure. Run the wire through the hole in the lid and in the spring, while it is 15 mm from where the spring is soldered. Bend Spring country by gently squeezing over the area of solder with needle nose pliers as spring bent. Slip the wire by hand newfound spring. Do not let the bare wire touches the spring. Solder wire on top of the other lead halogen bulb. Put halogen bulb at one end of the box. Gently pull the spring the other end of the box and to extend a quarter inch past the edge of the box. Screw the end cap of the spring so that the spring is passed through the opening. Keep screwing until the lid is tight.
Pull the wire through the country of spring. Solder wire lead from the example of halogen bulb that does not have spring soldered to it. Put halogen bulb at one end of the box. Gently pull the spring at the other end of the box. Screw the nozzle so that the spring is threaded through it.
Tighten the cylinder cover of the box by continuing to screw the lid spring. The other lead of the wire must be soldered black wire from the battery terminal connector with 9 volt (cut the red wire). The second end connector should distill the wires at the base terminal and are then welded together before the rest of the wire that hangs along soldering is cut. A third terminal connector should have red wire soldered to the same lead halogen bulb by the spring. Cut the black wire from the terminal connector third.
Connect two 9 – volt batteries as the second terminal connector (no cables attached) and click it to both batteries. Connect terminal connector red – wired one of the battery terminals. Do the same with the other battery. If the pressure switch fails to attract, switch batteries various terminal connectors to fix the problem with a hook to the wrong conclusion. Insert the batteries inside the box.
Slide two zip ties through the handles of the bike and let them cross. Within this cross area, drag the box in position so that the box is perpendicular to the handles. Before tightening ties with zipper completely, move the box to the desired position. The light should be pointing towards the ground in front of the bicycle, and enough ahead to see each night time traffic, including pedestrians.
