Being seen when youre biking is incredibly important, and whileweve shown yousome ways to addsignals to your bike before, this method is easy, runs for ages on a single nine-volt battery, is bright as all getout, and is a perfect primer to electronics projects.
Youll need about $20 worth of supplies to make this happen, and the finished product is extremely long-lasting (the circuit is completely off when not in use, so the battery doesnt slowly discharge), its small and light so it doesnt get in the way while you bike, and its super bright, so drivers can clearly see you, and the direction you plan to go.
Instead of an Arduino or another microcontroller, Tom decided to wire this up from scratch, with a collection of wires, resistors, diodes, and capacitorsall stuff you’ve got the option to find at a hobby store or online.
Check out the full buildincluding the parts list and the circuit diagrams youll need to replicate it yourself at the link below, and you could get a good idea of whats involved with the build in the video above.
