Pedal insert LED lights for Gotway unicycle

thingiverse

This is a special housing designed for one rechargeable battery, three lights and a mercury switch. Its compact size allows it to fit inside a Gotway MCM2 and MCM3 ( but not MSuper or MCM4 ) unicycle pedal, giving users an easy way to be visible while riding their wheel as seen in the attached video and picture. Depending on the type of light used, different effects will result. Two lighting options can be viewed here:https://www.youtube.com/watch?v=GVOQImmvStY&feature=youtu.be They automatically turn on when the pedal is unfolded here:https://www.youtube.com/watch?v=zSM35KjcctA Parts required for this project are as follows.Mercury switch can be obtained from http://www.ebay.com/itm/141807317185 Batteries and charger are available at http://www.ebay.com/itm/181725362921 Prototype PCB is available at http://www.ebay.com/itm/400985368376 Battery spring plate sets can be found at http://www.ebay.com/itm/231239955456 Leds are also available at http://www.ebay.com/itm/400985246280 To complete the project, users must solder three lights onto a piece of PCB in parallel (not serial), wire to battery spring plates with mercury switch in between. Next, they must insert all components inside a case and turn the mercury switch at the right angle so that power is turned on when the pedal is down. This can be tricky and may require tweezers for precise control.Adding soft foam to one side of the case allows it to stay in place once inserted inside the pedal.Users who participated in the world's biggest unicycle gathering last week end requested this information as seen in the attached videohttps://www.youtube.com/watch?v=Hdt5KFjgPQI When selecting leds, consider using multi-colored lights that can withstand 3.7 to 4.2 volts of battery voltage without damage. Note that some Leds may fail when exposed to less than 2V, so it is essential to check them before using.The inclusion of diodes can lower the voltage while maintaining constant current and prevent damaging leds.
