Hybrid Bike Computer

This PCB is a Cheap solution to track your training preformance

Based o esp32 , reed switch sensors and a smart phone APP

You can upload your training to Strava if the App is linked

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.
