I've neglected to post for quite some time being busy with the holidays, snow, and wrecking my car. I survived, the car didn't. I hate shopping for a new car in the winter, but that's taken care of now.

In the last post I mentioned I was working on designing a bunch of...

GPS was functionality I integrated very early in the project since it was key to the whole project. I selected the Navspark-GL development board for my prototype. It's an Arduino compatible GPS/GLONASS module, which means it can be programmed using the Arduino environm...

I've now integrated a micro-SD card into the project. Originally, I never planned on putting storage on this device and was hoping users would just collect the data on a cell-phone or other connected device. But after some feedback from interested parties, I decided to...

If you recall my last post, I was seeing lousy throughput over WiFi using the ESP8266 module. I had decided to write new firmware for the module based on the Arduino Core for ESP8266 project. That project provides the base SDK from Expressif (the chip/module maker) and...

My original plans for this project did not include OBD support. My bike doesn't have an OBD port, just a direct connection to the CAN bus, and that was all I was planning on building for. In addition, I was only planning on supporting RaceChrono on the software side fo...

Before I forget, I should mention this will be my last post for a few weeks as I'll be taking a long awaited vacation. Hopefully the break will inspire me in new ways.

I've been working with KiCad and I still like it, so that's something. The schematics for the design a...

In order to write and test firmware on an MCU, you really need to hook it up to the peripherals it's supposed to control. Here's a picture of my main protoboard as of today:

It's a mess of wires, but it works.

On the left, with the USB cable plugged in, is a Teensy 3.2 d...
