WHy ride like the rest of humanity when you can turn your bike into a robo-shifting supermachine? This Instructable by programmer and maker Nabil Tewolde shows us how to create a push-button-controlled electronic derailleur system with parts you can pick up at your local electronics shop.
The key to the system is a mini servo from HiTec as well as a small Arduino board. Two buttons control the shifting up and down. It’s a bit complex but it’s a wild hack that could keep you busy for a few days if not weeks.
Why would you want to do this? As Tewolde writes: “Adding electronics to anything is always cool!”
