 | | Re: sensor input mux calculations —
| | | | I've thought about this, but I've come up empty. If you could get between the input line and the 10K pull-up resistor, it would be easy. You could then wire the CdS cells on either side, with a 10K resistor from one cell to ground. Then when the (...) (25 years ago, 31-Dec-98, to lugnet.robotics)

| | | | | It is not a 100% passive solution, but I added a very simple Differential Light Sensor to my web page. It really isn't that hard to build and all the parts come from RadioShack. You can find it in the "Homebrew Sensor" area of (URL) a good New Year. (...) (25 years ago, 1-Jan-99, to lugnet.robotics)
