Arduino IR Lap Timer
Here is my original arduino-based IR Lap Timer. It responds to an AIM beacon code. The display is in hundredths of seconds, with 4-digits allowing a maximum lap time of 99.99 seconds (no decimal point is displayed). However, the device … Continue reading
GPS Based Predicitve Lap Timer Project
Teaser Alert: Here is a picture of a project I’m currently working on: GPS based predictive lap timing. As you can see in the picture, I’m using an ATmega32U4 based Teensy USB Dev Board and a LOCOSYS LS20031 5Hz GPS. … Continue reading
