  VanSpoof - Prototype 2 - Echo Firmware

  In part 1 and part 2 of building my first VanSpoof prototype, I managed to flash the microcontroller on the PCB with a blinky demo. This time round, let's see about sending and receiving some serial data.

  Next Trains

  My two-year-old loves trains so any time we can swing past the station and see them is worth the detour. This web app displays the next few arrivals and departures to help us schedule a visit. It's also my first time publishing code as a package on PyPI.

  Reverse Engineering a VanMoof e-shifter – Part 2 – Decoding the Signals

  Now we've tapped in to the wiring of a VanMoof e-shifter, let's work out the baud rate and format of the data being transmitted and which format of messages are being exchanged between it and the bike.

  Reverse Engineering a VanMoof e-shifter – Part 1 – Connectors and Connections

  The most common and dreaded complaint for VanMoof owners is "Err 44". If I can reverse engineer the communications between the bike and the e-shifter, I should be able to build a replacement module that spoofs the original. Let's identify the wiring involved.
