(...) Andrew, I've putzed around a bit with the system you've discribed. Its called X-10 power line carrier transmission. (P.L.C.) The codes format was setup back in 1978 for Sears and Radio Shacks Plug 'n Power system. Since then X10 Powerhouse has (...) (28 years ago, 28-Dec-96, to lugnet.robotics.handyboard)

hello. While this question doesn't pertain directly to the handyboard, I thought I would post it here since I am using the handyboard in my project.

I can hardly contain my glee! After 3 weeks of fun-yet-obsessive, marriage-threatening, Xmas-be-damned behavior, I've got all four IC and OC interrupts going, receiving/processing/outputting 4 RC PWM signals. This is only a side-note for Handyboard (...) (28 years ago, 27-Dec-96, to lugnet.robotics.handyboard)

The whole issue of null (inverted) connections vs. straight-through is incredibly confusing, because you must take into account the gender of the connector (male pins or female pin sockets) in determining whether it is a null connection.

Fred, Thanks for giving us this great design. I appreciate it and I enjoyed building my Handy Board from a kit. I do have two corrections, though. No big deal, just typos.

It doesn't have to be 1/8 watt, 1/4 or 1/2 watt is fine, just make sure it is 2.2 megaohm. (...) So far so good. (...) There is probably (...) (28 years ago, 26-Dec-96, to lugnet.robotics.handyboard)
