Resources¶
- Evidence of need
- Similar products
- Moving from keyboard to joystick interface
- 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)
- Bulk programmer for Arduino
- OSH Park - community PCB order site (great review on G+)
- Submitting Arduino Projects to the Arduino Blog
