This remote represents my journey from knowing absolutley nothing about RF communications, to a little bit.
Built from scratch, the remote runs off a PICAXE 28X2 processor, powered by a pololu voltage boost. This means only one AA cell is required to run the device. It seemed a shame to tie up that lovely little (smaller than my very bitten thumb nail!) volt boost in just one project, so with a little prior thought, I constructed the remote with the intent that the volt boost would not have to be isolated to just this project. Video's explain all!
What is to come next: when my order arrives i'll also be adding an IR LED which opens the door to another level of control possibilities.
Thanks goes out to fritsl for a rock steady transmission protocol to build off, and to Rik for some good transmission related advice.
The corresponding transmitter and reciever codes are attached, but they are still a work in progress.

Has the potential to be a slave-master to any of my projects.
- Actuators / output devices: RF link 315MHz
- CPU: PICAXE 28X2
- Power source: 1 AA cell
- Sensors / input devices: Mini momentary push buttons
- Target environment: Anywhere in range
