Ace R/C Pulse Commander
I need a Ace R/C Pulse Commander add-on switcher kit schematics or whole unit or a receiver with one built in. Also interested to buy or trade for Pulse commander stuff.
Thanks,
Bill

Does it need to be the "add-on" switcher? As a youngster I built one of these it worked well. The info I had was trashed years ago. However, I have a schematic to another 3-transistor design that works just as well as is easy to build. If interested, I will dig it up and post it.

This actuator switcher article was published in the Sep-Oct 1966 Issue of Grid Leaks. I had to cut up it up into three images to get it to fit within the file size constraints of this forum.
The transistors are a bit dated. This evening I prototyped the circuit using PN2222A's for Q1 - Q2 and a PN3906 for Q3. It worked fine. If you used SMT parts the final board size could be smaller than a R/C connector.
The R/C Rx must be a traditional relayless type that can drive about 500mA (or whatever current your actuator needs). The three transistors form a partial bridge amp and the forth needed transistor is the one in your Rx.
The article mentions motorized actuators. This will also work with two-wire (single ended) Adams type magnetic actuators or the like. That is what I used it for back in the good old days -- built several of these and they all worked like a champ.
The R4 resistor is used to current limit the actuator current. I suggest 10 ohms as shown (or omit it if you are using a high impedance coil type actuator (Adams).

Hi, Thomas,
As one of our grandchildren would say, Thank You Too Much.
Your info is exactly what I need and very promptly posted, too.
I have a Pulse Commander presently in the mail with a three wire Stomper plus an extra Baby Twin with two wires. When it gets here I will proceed. I haven't seen a Baby Twin in years, but seem to remember it can be changed to a baby. Will wait and see.
Thanks,
Bill
