Hello
I am making some simple RC projects using these cheap Chinese remote control units like these
http://www.ebay.co.uk/itm/433mhz-RF...50451540861?pt=UK_Gadgets&hash=item51988a237d
They work fine, but the outputs toggle and I need them to be momentary. They use the chip SC2272-T4 as the decoder and as far as I can see there is no option to convert it to momentary mode. (The SC2272-M4 seems to do this but I'm reluctant to try to unsolder/replace one chip with another).
Any ideas? I can't think of any way to make a toggle output into a momentary one:
(The advantage of using these units is that they are cheap and come with a ready made keyfob transmitter: everything else I can find seems to be quite a bit more expensive and would need me to provide a transmitter housing/power supply/switches etc.)
