- Raspberry Pi (I used zero W)
- A connection to a reed switch on your bike. Mine is the cheap Ultrasport brand (F-Bike)
- Mine has a 3.5mm jack. I chopped up a spare usb to line in cable I had, and trimmed the wires
- A 1k resistor
- Jumper cables / some wires to connect the Pi to the sensor
- Solder / crimp cables (this is what I used to avoid a soldering iron)
