From pdavila at thelinuxlink.net Mon Mar 1 07:51:28 2010 From: pdavila at thelinuxlink.net (Patrick Davila) Date: Mon, 1 Mar 2010 07:51:28 -0500 Subject: [Lvlug] Unloading my black G1 phone for $100 Message-ID: I'm looking to sell my T-mobile HTC G1 phone for $100. The phone is unlocked & rooted and running the cyanogenmod custom ROM which has a bunch of tweaks: http://www.cyanogenmod.com/ The phone runs faster than the stock T-mobile ROM and has the ability to do wireless tethering and install apps to the SDCard. The only issue I have is I'm unable to mount the card on a PC via the USB cable. You can still copy files from/to via wifi or just pop the card out into a usb reader/writer. The phone charges fine over usb. I have a hardshell case as well as the original usb cable. If I get no takers I plan on selling the phone on Ebay. Stock G1s are currently going for around $150-$180 on Ebay. Let me know if you're interested.

Sounds like fun. I look forward to seeing it in action. See you Saturday!

I was originally considering bit-banging a parallel port, but this seems like a perfect opportunity to play with an Arduino. I believe there are a handful or Arduino enthusiasts on this list... so, my newb question: are any of the ports on a Duemilanove able to close a circuit? Or do I need an external relay for that? (e.g., to emulate pushing the garage door open/close button.) ~Keith From mstanley at technologist.com Tue Mar 23 21:33:43 2010 From: mstanley at technologist.com (Mark Stanley) Date: Tue, 23 Mar 2010 21:33:43 -0400 Subject: [Lvlug] arduino question In-Reply-To: <4BA8FA49.6030802@lehigh.edu> References: <4BA8FA49.6030802@lehigh.edu> Message-ID: <201003232133.43705.mstanley@technologist.com> Hi Keith, It is a very slim possibility that you could connect your Arduino directly to the button contacts. You would have to make certain that the garage door controller uses a TTL input for the button. It's pretty risky if you are not certain or don't know what I mean by TTL. If you do know what I am talking about then you need to know that a port pin can source 60mA and sink 50mA. If you use a relay then can you avoid all the problems with trying to figure it out. -Mark Stanley On Tuesday 23 March 2010 01:28:41 pm Keith Erekson wrote: > I'm hoping to do some dabbling in home automation, specifically > concerning my garage door.

Maybe it's 9V nominal, or was at one point anyway. This thing is pretty old-school. I think might be older than I am. If TTL levels were enough to trip the garage door's relay, the Arduino should be able to drive it, right? Maybe with a diode in front of it, so that the 8V on the line doesn't cook it? Of course, at the point where you're worried about damaging your hardware, I guess the $2 relay is a worthwhile investment. On a related note: has anyone played with 1-wire on the Arduino? I currently have a 1-wire temp chip (Maxim DS1820?) in the garage (and a few in other places), on a crappy 1-wire to serial adapter. I'd love to replace it with the Arduino. A quick google seems to indicate that it's possible (and that people have trouble with it). I also ordered some magnetic reed switches yesterday. The idea is to have something alert me when I leave the garage door open after midnight or so, and let me close it without going "all the way" to the garage, or be able to let people into my garage remotely without giving them the PIN for it, etc. Has anyone attempted something like this? Any wisdom to share? -Keith Mark Stanley wrote: > Hi Keith, > > It is a very slim possibility that you could connect your Arduino directly to > the button contacts.
