So I had a lightning hit fairly near the house a while ago that cooked a couple things... had to replace a cable modem, but everything else on the network seemed to survive ok.   I just recently realized my WebControl stopped responding on the network and I'm trying to figure out if it's toast...

I'm a software geek, so I like to make odd choices if I get a learning experience with circuitry out of it. :) Well, that and I don't have wires all over my dash to plug into the front of the radio if I go this route.

Morning all, I have an older first gen XM radio in my car that I'm tired of coaxing to change channels, so I'm switching to a newer one that the wife just abandoned because her new car has XM built in. A long time ago, I plunked down 70 or so dollars for a box that both powered my radio and...

I discovered the WUnderground API last week (which is awesome, btw) and have been coding a free-as-in-beer HS plugin in my spare time... should be done by next weekend if I can get work to stop breaking things. Even if nobody else uses it, I will. :)

I didn't see this in a search, so... I know this is a little dated, but someone presented a bit on Hacking home automation systems at DefCon 2011. Most of the articles refer to how vulnerable X10 is (which is a joke to anyone that's ever used it... of COURSE it's vulnerable, ask anyone who's...

That's exactly right, and it all makes sense to me now. The WebControl leaves the TTL7 output high the entire time to act as Vdd for the IC, and then the transmitter is toggled via TTL8 - based on whatever house code/unit code you've told it to transmit. Très Cool. I went down the rabbit hole...

Hm, ok... So do I have to leave the card attached to the DB9 shell or can I just wire it directly to the WebControl? If we're keeping what was previously the RTS and GND pins, does the new diode on IC pin 5 take the place of the brown wire that was the DTR signal?

I happened to be on the CAI website a while back and discovered that they now have X-10 support cooked into the 3.1.x PLC firmware. That got me pretty fired up, because I have a project that would be easily solved by the WebControl blasting out X-10, rather than waiting for the time (and lower...
