Also people would probably be reluctant to drill holes in their guns for the LED and mode switch. The circuit also requires a very high quality regulated power supply (preferably over 20 volts). I'm still searching through all my junk trying to get a better p/s. The circuit also has to be calibrated to the p/s. I'd have to redesign the circuit to reside in the cab. I could make it support 2 guns with pots to calibrate fire rate and recoil timing. There could be connectors to hook up an external mode switch and LED. Also the microcontroller could be powered from a keyboard encoder with a secondary power supply just for the solenoids. This would allow the circuit to work with a cheaper p/s assuming an IPAC can power the relay. Or maybe I could replace the relay with an opto-coupler (I'm not sure if they make opto's that can handle over an amp). I'd also probably have to get a more expensive microchip to support the additional inputs and an A/D converter. If there was enough interest I'd consider it. But for now, I'd be happy to offer advice on how to build it yourself. |

I found a great power supply to provide gun recoil at 24 volts. I got it from an old broken Lexmark laser printer. It can fire the solenoid at full power with amps to spare. The quirks I was experiencing with the cheap laptop power supplies have vanished and the circuit now works flawlessly. The p/s is almost too nice to use for recoil. I could probably power a CNC router with it. It also outputs 5 volts and I will probaby add a regulator so it can do 12 volts too for my marquee lighting. I was lucky to rescue this printer from the garbage collector. There are probably many of these 75 pound behemoth printers out there that cost more to fix than they are worth. Lexmark may make POS printers, but their FDK p/s are high quality. |

I added a variable resistor to my recoil interface. Now the fully automatic fire rate can be adjusted. I also posted the AVR code. |
