Hi all,
My project right now is a simple setup: Three 9v batteries and a 2.64mA current limiting diode all in series. (Okay, sometimes I also add various anode/cathode pairs and the occasional light bulb or ammeter.)
What I'd like to do is have it automatically reverse the anode and cathode every minute or so. I'm familiar with *mechanical* relays and DPDT switches, but as far as solid-state electronics goes I'm a newbie who's thus far just made up my theory as I repair one bad part of a circuit that someone already designed and built for me.
I've seen some similar posts but they all involve mechanical objects bumping into toggle switches.
In theory, it seems like I should be able to wire up a 1-minute bistable 555 chip to a DPDT relay which goes to my cathode and anode.
However, since the main circuit is 27V I'm assuming that I'll need to isolate a second lower voltage circuit for the timer... and I have no idea how that will affect my overall output.
So my questions are:
Is this the right approach?
Is there a solid-state (non-relay) way to do this within one 27Vcircuit?
Advance Thank Yous,
