Ive just finished my Nrf S/C transmitter,
The case is a hammered finish courtesy of CamdonBoss enclosures.
It's quite a small casing measuring only 63x112mm and about 25mm depth. I had to 3d print a 3mm gasket for it as the meter was just slightly too deep for the case, printed in ivory colour to match the button.
Electronics were straightforward apart from it being really tight for space. No PCB, just wire on the fly and hot melted into place.
I done the usual mod to the meter using a zener diode and a resistor. Thanks to PaulJ for the Futaba meter, works beautifully.
Ive used a different technique to make the nameplates, they are black anodised aluminium business cards that ive laser etched the lettering and graphics on. The difficult part was cutting the plate once etched, not easy to keep flat and get perfectly straight, ive done the best job I can on those but very happy with them, the main advantage of this method is you can't scratch them off and are very nice looking.
Its powered by an 850ma 2S lipo which gives a good endurance.
Antenna bezel and ivory button are both 3D printed
The DS438 switch I had, had a problem, as in the plunger was broken at the top so no button could be attached, Ive managed to 3d print another for it.
Photo and STL file below including the button too
Im very pleased with this build, it feels extremely solid and a quality product, also seems to be well balanced and just feels right in your hand.
Don't you just luv proper single channel? Thanks for reading
