As leaders in the Do-It-Yourself community we support the Maker's Bill of Rights. The M133S is a finished product ready-to-use, but if you're a hardware or software hacker there's plenty of ways you can customize it further. It'll void your warranty, but we'll help!

Here's the hardware schematic for the m132s to help you on your way: m132s Schematic.

Here's some simple hardware hacks you can do yourself:
- swap in a lithium battery (the existing low-battery warning is perfect for a lithium-protector - just make sure you turn off the power when you start seeing it)
- make handlebar mounted control buttons by using magnetic switches in parallel with the on-board buttons
- power two units from one set of batteries
- mount the batteries on opposite side of the wheel from the unit, to balance the weight
- For a harder project try connecting the m132s to a hub-generator for battery-free use - see the FAQ for more info.

The m132s ships with a standard Atmel AVR 10-pin connector that you can use if you want to reprogram the m132s with your own code - experienced embedded systems hackers only!
