  • PC Gamer Bike
  • BitGym
• Sensors considered
  • Rotary Encoders
  • Homemade Rotary Encoder - used in very first prototype, but quickly abandoned because the mechanical interface was difficult to maintain
  • Reed switch (Link 1 | Link 2) - v0.1 and v0.2 used reed switches (originally off of an old Bike Computer, now purpose selected)
  • Hall Effect Sensor - under consideration for v0.3
    • Arduino Playground
    • Blog post covering three types of Hall Effect Sensors - this is a very good resource, especially with respect to the types of sensors to consider
    • Arduino post on using Hall Effect sensor to measure RPM
    • Forum post about measuring RPM and resetting to 0 when motion stops - lengthy discussion and covers many of our goals
    • Forum post about calculating RPM on a bike - not really enough details here, but still documenting it
• Evidence from Reddit that there is a market for Holoseat
• USB Tester from Adafruit - might be useful for later prototype development
• Data Smoothing - Arduino tutorial dealing with smoothing out noisy data
• Production & Design Work
  • Monday Experiment: Bootloading an ATmega32u4 with Arduino - minimum electronics necessary to create a Leonardo clone, important documentation for building completely custom PCB/Shrinkifying the Holoseat
  • PCB Routing Service - Team at Dangerous Prototypes provides PCB routing/layout service for OSHW projects at $35/hour (3 hour min)
