Projects for the New Place
Been thinking a bit lately about projects to keep me busy in the new apartment, and I’ve got a couple of ideas that I think will be pretty neat.
First, I’ve been interested in tracking the temperature in my apartment. There is only one thermostat, and I can’t think of a good way to pull any info off of it, so I’ve been looking into other sensor equipment. The iButton stuff looks pretty promising; the temp-only sensor buttons are pretty inexpensive, and the HA7Net looks like a good way to interface to them without having to mess around with line level protocols. Since I don’t use the landline phones, I’m thinking I’ll cut off the connection to the phone company and reuse the existing phone jacks in the apartment to make a 1-wire bus. Just solder an RJ-11 plug onto the temp sensor iButtons, and I can put a sensor everywhere there’s a wall jack! The controller is about $155 and the sensors are $7.50/each in the quantities I’d be looking at.
The other thing I’d like to monitor is power consumption. I’ve got a Kill-a-watt, but that only works for a single outlet. I’ve been eying The Energy Detective, which installs into your breaker panel with a number of inductive probes and a connection to communicate it’s readings over the power lines (similar to X10.) The only problem is their software is currently only for Windows. The older version had a serial port on the receiver to communicate with, the new version has USB, and I suspect it’s just a USB to serial adapter of some kind. To do what I want to do (feed the data into Munin) I’d have to figure out how to talk to the thing, which might make for a good project. T.E.D. sells for $145.
I’m also going to need a new vacuum cleaner. The old one is Delia’s, so it’ll be going away. I’m leaning toward spending the extra money and buying a Dyson, specifically the DC 25. The reviews are all very good on them, and it sounds like they last forever. Seems like one of those things where it’s worth to spend the extra up front and get something you’re happy with instead of skimping and replacing it later because you hate it.
