How to built a Hybrid Bike Computer
Story
I am a bike rider, so as Maker I was thinking how to make a Bike computer using a cheap device and an open source or free APP. To avoid inconveniece and make my solution functional I bought, and add to the solution, a heart rate sensor. ALso I use CATEYE APP free version and STRAVA APP, free version.
So I have find an easy solution, mount the sensors for speed and cadence(based on reeed swithces) and the computer in my bike and enjoy a lot.
The idea and service of this dvelopment is to understand my performance riding bike, so I need telemetry and, why not, some video sinchronization. This is a reference what I do with my bike computer , my smart phone camera and one chest support gadget:
What for my hybrid bike computer DIY based on ESP32:
Sample one
Sample two
Enjoy the sightseen.
The tutorial about how to built this project, being based on ESP32 and oriented to BLE , can be watched in the following video:
In the near future i will make the Version 2 with a PCB and the case 3D print . DIY heart rate sensor after a lot of investigation and tes is not good and functional at low cost. So I willñ keep using a commercial brand sensor.
