Hi all,

Just a small update with hopefully bigger ones imminent. I have received my new Tracer boards that are now smaller and have a better-suited LDO with a very low forward drop to increase the usable range of battery voltages from the coin cell battery.

I am currently planning the following activities; 

  1. Testing it out for tennis stroke counting - Done
  2. Tracking bicycle cadence - Done
  3. Using it to synchronize blade strokes at my local rowing club 
  4. Power measurements and optimization - Done
  5. Syncing with camera footage to add data points and improve the usability 
  6. Create a Tracer "hub" to synchronize several modules. Still thinking about the best way to do this as BLE might be a little limiting. Feel free to suggest :) 
  7. Setting up a Crowdsupply campaign to get the hardware out to you! - On Tindie for now

Thank you all for liking and following this project it means a lot to me and it helps me keep going!
