Macgregor NRF24 FHSS Digimac 1+1 project
Posted: 27 Mar 2024, 10:06
After viewing the Codamac on ITV's The Royal, It spurred me on to dig out an old Digimac 1 I had hidden away in the dreaded Bermuda Triangle cupboard.
I just love the look of the old blue anodised digimacs. After having a quick chat with Phil I decided I was to convert it to a FHSS Digimac 1 plus 1 system. The Digimac 1 without the plus 1 is great but definitely lacks the functionality of having a throttle, So the plus one it was going to be.
My method is to use that green perfboard stuff, not sure of the correct name but I just like the way you can place your components anywhere you like and just wire them underneath. Everything is mounted on this pcb including the RF module, 3v3 regulator and buzzer.
Jst-Xh sockets were used for the stick pot and throttle switch.I designed a 3d printed tray for the pcb to screw to, keeps it neat.
Transmitter is now complete,
The only thing I'm not 100% happy with is the push button switch, its slightly smaller than the original type used on the plus one, if anyone has a spare, it would be very much appreciated.
I decided to model the receiver on the blue plastic type Macgregor receivers, think they are the "A" series versions. The case is 3D printed in Blue with a screw on bottom. Separate fly leads were required for the servo outputs so I made these up with fresh twisted wire and Dupont connectors going through 6mm rubber grommets.
To finish it off I 3D printed a period battery case in black with fly lead output. Inside it's fitted with a 1s 550ma battery.
Many thanks to Phil for the FHSS 1 plus 1 sketch. Im super pleased with how its turned out and is a really useful edition to the collection.
Don't you just love bringing 50 year old sets back to life.
Now for the retail box!!!!
Here are so photos of the finished project
