Great article. I’ve grabbed a few of the remotes; prices varied on ebay from $30-$70, but I was able to get a few versions:

I use one 300mhz tx/rx as a safety on the main 433mhz 12ch tx/rx, and a third 500 mhz unit for transmitting back confirmation signals of arming & continuity. The system is used for High Powered rocketry, and adds a little flair to the firing range. If we’re going to geek out, we might as well look official, eh!

I’m officially stealing your car charger circuit idea; brilliant.

I made a varations on this, so i have now the ability to shoot 48-channels. The only thing i have added is an extra 4-channel remote system which control the minus lead of 12 channels per remote output channel. In this way you can expand your system without high costs or huge space requirement. Here is a link of a picture of my system. I put the other 16 connectors and 3 LED's on the back of the case.

I probably worked on it for 3 weeks during my spare time.
Major components/cost breakdown:
• 12 channel wireless relay controller (search ebay for “12 channel rf”) – $40
• Sealed lead acid 7AH 12v battery (available online/in-store at many places) – $25
• Battery charging circuit: took mine from an old car jump-starter – $free*
(*or buy a new one and forgo the purchase of a separate battery)
• LEDs, resistors, speaker terminals, and wire ( partsexpress.com) – $40
• CD case Housing (any well built box will do) – $20
• 40ga Nichrome wire (ebay) – $3
• More black powder than I needed (sporting goods store) – $15
• Miscellaneous components – $10
Total: $153

How long did this all take you and more importantly how much would it cost.

Great project, i would really like to build on of these for my fireworks show.
