Hack your own wireless leash

Starting with an off-the-shelf Nike + iPod transmitter [top], I removed and modified the circuit board [second from top]. I constructed a receiver from an Arduino Pro Mini microcontroller and a Nordic radio chip [second from bottom]. Then I repackaged the transmitter to make it easy to replace its battery and switch it on and off [bottom].
