I’d like the LED of the MK120 receiver to stay on for several seconds after trigger. I’d also like to power a bank of 6 LED’s, instead of the single LD1. Has anyone created this modification already? Can you suggest a schematic? I’ve looked at 555 one shot timers circuits, but they typically trigger on a “low” pulse. Thanks.
You could use the VM141 timer, but you will have to replace the MK120 buzzer with a relay to trigger the timer.
