 | | Touch Sensor as a Switch
|
|
I played around with sensors and wires, and came up with a way to use the touch sensor as a switch. See my post at lugnet.cad.dat.ideas (URL). Unfortunately, even when the touch sensor is pressed, it still has a significant amount of resistance, so (...) (25 years ago, 25-Aug-99, to lugnet.robotics)

From: "Hao-yang Wang" <hywang@pobox.com> (...) Could you put a JPEG or GIF rendering of the image on the internet somewhere for those of us without LDraw? thanks, alex -- Did you check the web site first?: (URL) (25 years ago, 25-Aug-99, to lugnet.robotics)

(...) Can you describe that? Are you connectiong the Lego wires with only one stud overlapping? I don't have software to display your LDRAW file. (...) Very, very interesting. I wonder why that is? Maybe Cybermaster has really only one analog input (...) (25 years ago, 25-Aug-99, to lugnet.robotics)

(...) It consists of one touch sensor and three connection wires. The plates overlap each other by two studs, but because of the orientation of the metal part in the stud, only one stud is actually conducting. The drawing in JPEG is available (...) (25 years ago, 25-Aug-99, to lugnet.robotics)

In response to my own post on the Cybermaster touch sensors: The three different Cybermaster touch sensors have a resistance of 15k, 12k, and 10k when not pressed. The rest of my ramblings were pure fiction. The three Cybermaster inputs are (...) (25 years ago, 26-Aug-99, to lugnet.robotics)

Tilman Sporkert skrev i meddelandet ... (...) It's for the CM software - it's targeted for younger kids than the RIS. As the sensors have different color (and open resistance), the software assumes you build the models as described, and then just (...) (25 years ago, 26-Aug-99, to lugnet.robotics)

(...) My guess would be that it lets you determine which colour switch is attached to each input, when it is in the open state. Kind of a nice idea actually - just attach a switch to any port, and the GUI can remind you which colour sensor is (...) (25 years ago, 26-Aug-99, to lugnet.robotics)

(...) Connecting N touch sensors in parallel requires N pieces of wire, while doing so in series requires N+1 pieces of wire. See? It's not that bad. Here is my experimenting results of connecting the three Cyber Master touch sensors to RCX in (...) (25 years ago, 27-Aug-99, to lugnet.robotics)
