    Hey Canobi, I'd love to see a short guide on how you made that press!

    Radio receiver controlled enable switch

    Not at all. This is one of the circuits I've needed where speed is not a constraint at all!

    Radio receiver controlled enable switch

    That sounds like it could be a clever idea, Gryd3! I've had an alternative idea as well, just want to run it by you guys to check its feasibility. Could I introduce a low pass filter to convert the PWM to an analog voltage, then use a comparator with a reference voltage chosen to distinguish...

    Radio receiver controlled enable switch

    Haha Bob, that is true, but I need this to be a small device without any moving parts. I guess my biggest question is how can I easily interpret a servo control signal as an enable (sustained high or low)?

    Radio receiver controlled enable switch

    Thanks for the prompt reply! Luckily this is conveniently provided by Futaba in the following format: Frame rate: 20ms Minimum position occurs with a pulse of 1ms Centre position occurs with a pulse of 1.52ms Maximum position occurs with a pulse of 2ms My control scheme will operate with a low...

    Radio receiver controlled enable switch

    Hi all! I want to make a Signal Interrupt Module for testing motor failure scenarios. The motor is controlled by an ESC that receives signal from a Futaba radio receiver. What I want to do is simply have an enable signal from the receiver either pass through the ESC control signal unaffected or...
