Well its finally complete! Ive finished building my remote ignition kit which is based on the RR12-CONF board from RFRemotech. Summary is as follows: RaspberryPi running a webserver with 36 buttons on it, each coded to various outputs of the RaspberryPi. It also has various buttons for starting and stopping music (run through Python scripts) and can read in a text file line by line to trigger cues in a certain pre-programmed order. The outputs from the RaspberryPi are then passed through optoisolators to control the remote control which came with the RR12-CONF kit (its an OOK AM remote control but I have manually changed the security bits so at least it is a bit more secure!). The RR12 kit is configured in 6M6L mode so can control 36 fuses and is powered by a 9AH battery in a toolbox so could theoretically launch hundreds and hundreds of cues before needing recharge. Obviously it needed full cue checking facilities and key ignition (as it wouldnt be cool otherwise ). Total cost came to about £90 in parts, but lots and lots of time - so I guess I ended up paying for me to learn some new electronics skills (Im an electronic engineer by background but have never done anything with RF, RaspberryPi or Python so there was plenty of new ground!) Insert slightly scruffy pictures of a device Im actually really proud of - I cant believe many people can launch fireworks from an iPad!!
