Well I finally got some Dallas Semiconductor 1-Wire Tempature Sensors in.  I quickly threw a bunch on the breadboard to see how accurate they are and stuffs, pretty nifty, 2 wires is all it takes, ignore the 3rd leg of the sensors it doesn’t do anything…

Breadboard + 1-Wire Temperature Sensors

I put white blocks in the picture because of the nonsense on the breadboard–it was just some toying of a segment display from awhile back…

I plan to use these sensors (along with many more) to build a weather station, and I’d like to place a few throughout the house to see the difference in tempature between the rooms.  Would be intresting to see the temp difference between the outside, attic and home on a graph.

So with a tip from a fellow on the internets, I was able to finish that last step in programming it, setting the link between a card reader and an output.  It was all working so I ran to install it, took a little under an hour and it works! w00t!!!111oneoneeleven

So I tinkered around today with it some more, and realized my mistake when I previously tried to program the panel.  Every command has to be prefixed with a space.  The other show stopper is the POS USB<->Serial Dongle I am using, it craps out after a few minutes and I have to change the com port, disable/reenable the device, or unplug/replug it in…

I made good progress today, Assigned the Reader to an Output, Added the Card to the Reader, and named the Panel, Reader and Output.  I cannot get the panel to energize the output when I have a successful read, however the LED status on the reader works now and I can see the actions in the terminal processing.  I know it has to do with the V command, but everything I’ve done thus far is invalid syntax, stupid Honeywell needs to improve on this documentation from 1995.  Perhaps I’ll try to get a firmware upgrade for this thing, apparently you have to send the EPROMM in to get it, PITA.   Heres a pic from my tinkering…

Also bidding on a Blackbox wireless serial server so once this is installed I can make whatever changes over the network…mmm disable someones proxcard (key) to the house via VPN–oh the joys…

Anyone else who wants to do something like this, the Northern Computers panels may be a cheaper solution since they are in surplus out of old buildings, however something like an ELK-M1 may prove to be more user friendly and alot less fustrating…

So I picked up this Northern Computers N-1000-II Access control panel from fleabay for a few bucks.  I’m working to make my garage door have card access, and then maybe the front door of the house.  Still haven’t figured out howto program it, the serial port spews out timestamps of events (alarm conditions, card reads, etc) you can program one of the 2 card reader inputs to energize a relay output when an “authorized” card is read..

So I picked up this wallmount rack a bit ago and finally threw it up there, it came with a bunch of patch panels filled with keystone jacks that will be installed throughout the house–since I already have a patch panel…  To the right is a Netbotz Wallbotz  300B to send me emails about the garage being 112 degrees….Florida fails.
