Hello. I am trying to construct a device similar to a transcutaneous electrical nerve simulator. I have built an astable 555 timer circuit which produces a square wave pulse every 6 seconds. However, what I would like to have is a circuit which produces a train of 50 Hz pulses, for an on time of less than 1 second, which repeats every 6 seconds with no output between pulses. I was wondering if anyone knows a way I might be able to accomplish this or modify my 555 timer circuit to do this? I thought that I might be able to use two 555 timer circuits, one producing a square wave every 6 seconds and another producing a continuous pulse at 50 Hz and somehow have the one circuit trigger the other, however I have not been successful. Any help would be greatly appreciated. Thanks.
