Wireless Ignition 18v Relay
grabcad
This is basically just a wireless relay. Taranis controller for TX and 8XR for RX. UBEC (Matek Mini Power Hub) takes 18v from battery (Milwaukee 18v Battery Adapter) and powers the RC switch. The RC switch is there to transform the servo signal from the RX into 5V for the relay. The relay closes the full 18v from the battery to the speaker terminals (Speaker Terminal 4p Electrical) in parallel. Green LED indicates unit is powered on and red LED is on while 18v circuit is live. I use it for reliable explosive testing. Many more ports available on the RX; I'll probably add a siren and perhaps an intercom for long range stuff. Battery is a modified version of Milwaukee M18 Battery. I stretched it out into an XC and slapped on some decals.
