Building a Wireless Kill Switch
When things become sentient, it's good to be able to remotely kill power.
I highly recommend building something that scares you every once and a while. In this case, I’m planning to enter an autonomous vehicle into the AVC in 2016, and it's pushing my limits of comfort. A 1,000W motor with a large battery pack behind it means that if things go wrong, they go really wrong!
The innards of the remote kill switch
For that reason, one of the new safety requirements of the AVC rules is a remote kill switch that allows the user to safely and remotely power down the vehicle. So here's a tutorial going into how I built the wireless kill switch based on the RFM69. And to demonstrate this... well... let's start with a margarita.
