There are a lot of times when it’s useful to be able remotely turn something on or off. In this instance, my son has a small Power Wheels car. I wanted to be able to turn the car off if he drives too far away, or in the wrong direction. So I designed a simple remote kill switch, which lets me turn the car (or anything else) on and off with a remote. As an extra safety feature, if the car goes outside the range of the remote, it will automatically turn off.
See the project on Instructables: instructables.com/id/Remote-Kill-Switch/
It would also be a good idea to use a signal that carries a code, so that not just any constant signal on the same frequency that stops by will stop the machine. Garage door openers and car key fobs have this so that your remote doesn’t give you a magic key to other peoples’ garages and cars. A machine that stops unexpectedly can also be dangerous.
Apart from that, great tutorial!
Hello Jason,
How hard would it be to hook a remote kill switch to a portable generator, such as a honda eu2200i?
Thanks in advance,
Jimmy
