Many thanks for the Turnigy tip👍 much cheaper than the 20 quid Action /Component Shop version 😉
I hated wasting channels, and multi-channel sets were horrendously expensive😡 so many many 🤔 moons ago I made my own 4 function switch decoder for my destroyer, home made PCB, a few 5V CMOS chips, driver transistors and 5V 5Amp relay outputs. Pics 1, 2 & 3. Gave 4 functions Nav lights, Signal Lamps flashing, Whoop Whoop siren, and smoke unit from one proportional channel. Still seems to work 30 years later!😊
Around the same time I added a winch for the crane on the stern deck and also made a home cooked PCB with a simple forwards / backwards motor driver; again CMOS chips, driver TRs and relays. Pics 4 & 5.
Pulled in well but there was no free-run mode on the winch so it needed something like a tin o' beans on the hook to run it out 🤔 .
Lovely smelly etching for the PCBs 😆 Ferrous oxide!? Or was it ferric chloride? Never did like chemistry, I was a physics man. But it worked😊
Most of the bits were sort of 'lying around' at work😉
BTW: if anyone needs CMOS or 7400 series TTL chips I still have pretty good stock!
Nowadays it's all plug n play and such things are miniaturising so fast one day they'll disappear up there own whatsits!
Back then half the fun was doing it yourself and squeezing the utmost out of a 2 or 4 channel radio. Happy days? 🤔
Cheers Doug (AKA Rambling Man😁)
Superb! I wouldn't know where to start.
One of my first boats was an Aerokits Crash Tender powered by a Frog 2.49cc diesel. The radio was single channel, one press of the button for right rudder, 2 presses left rudder, press and hold for throttle.
