Iambic pedals

by OH6DC



Previously I have built a simple foot pedal CW key (see here). But when I came across this two-pedal device I realized it could be connected to my iambic keyer.




Inside view. The pedals operate these potentiometers.




I connected the pedal pots in parallel with my ordinary paddle. Some serial resistors were needed to get it working all right.
