Striker is a real-time wearable cadence tracker

The Manifold crew has designed an open source hardware platform capable of tracking real-time running cadence.

Dubbed “Striker,” the prototype boasts both an Atmel powered wristwatch as well as an Atmel based footpod.

More specifically, key wristwatch specs include:

  • Sparkfun Pro Micro (ATmega32U4 MCU)
  • 850mAh lithium ion battery
  • Power cell (Lipo Charger/Booster)
  • SPDT mini power switch
  • Monochrome 128×32 SPI OLED graphic display
  • 
XBee 2mW PCB Antenna (Series 2)

Key footpod specs?

  • Fio v3 (ATmega32U4 MCU)
  • 110mAh lithium ion battery
  • 
Force sensitive resistor
  • Terminal block (2-pin 3.5mm)
  • XBee 2mW PCB antenna (series 2)

“Striker will remain in the lab for now, but hopefully something like this will become more readily available for runners everywhere,” a Manifold rep by the name of Chad explained.

“As far as a custom solution goes, rather than inventing a watch to receive and display the cadence data it would actually make more sense to build an app for an existing watch platform. Then all you need is a footpod capable of detecting foot strikes and sending the data along using a communication protocol that the watch platform can speak like Bluetooth.”
