Rowing Computer

OpenRow

A project to design an build an open source rowing computer. This project was born from the idea that I would rather throw something cheaper than a cell phone into the water, a secondary driver was how expensive existing options are given they are in effect a specialized pedometer.

Goals

1. Hardware and software for an acceleration based rowing computer similar in functionality to a variety of apps available for phones.
2. Speaker/Headset module integration (module provides headset functionality existing computer provides rowing data), which fits into existing headset amplifier form factor.
3. GPS & Bluetooth
4. Fitness platform compatability.

Secondary Goals

1. Floats
2. Impeller Integration

Design

This is purely a personal hobby project at some point it may make sense to use a funding platform to do a medium sized run with assembly but there are no plans for this. I have no background in EE.

Circuit

I have used kicad 5. Its free and open source, you can use whatever tools you wish but you need to ensure the files in the project remain comatible with kicad.

PCB

The current design is built to JLCPCB 2 layer design rules, I have no solution for providing multiple pcb's which would allow designs for multiple fabrictors. It is likely in the future to ease the design of RF components I will move to a 4 layer design.

Assembly

Stencil and hand assembly with a homebrew toaster oven reflow setup for prototyping and testing.

Case

3D printed - in progress

Software

In progress

Commercial Use

If you use this project commercially reference to its usage on the consumer device is desired but not required under the licensing terms.
