| | | I created Mark Tarrabain's single pressure/single piston AND gate and have it all four possible input states. In this case I use rubber bands to compress the pistons, but this is not the only way to compress the pistons. (URL) is a picture of my (...)

| | | | | | (...) You are welcome, and thanks Robert. The full adder has three inputs A,B and carry in, and two outputs sum out and carry out. SumAB = A XOR B Sum out = SumAB XOR Carry in Carry out = (A AND B) OR (SumAB AND Carry in) You need a total of 2 XOR (...) (21 years ago, 21-Jun-03, to lugnet.technic, lugnet.robotics)

| | | | Wow. Thank you so much for the acknowledgement, Kevin. I am genuinely flattered. I've got a bitmap made of the schematic for my 13 switch full adder. It's strictly representative, and not meant to imply how the switches would be positioned in the (...) (21 years ago, 22-Jun-03, to lugnet.technic, lugnet.robotics)

| | | | (...) Well, I didn't invent the single piston gate. I give credit where credit is due. As I said in a previous post. Your single piston AND gate design was inspirational. I talked myself out of this in the past because I could not figure out how to (...) (21 years ago, 22-Jun-03, to lugnet.technic, lugnet.robotics)

| | | | (...) Okay... I've added arrowheads to each line showing air flow direction. The switches are set up so that the center port is the conventional inlet, and the top and bottom ports the outlets. I say conventional, because I don't always use it that (...)

Now I have to study the design so I understand how you did it. There's are a (...) (21 years ago, 23-Jun-03, to lugnet.technic, lugnet.robotics)

You don't wanna know how long it took me to get the wiring on it just right so that I wouldn't be committing any pneumatic violations. I'll try and explain how I (...)
