Missed It

Posted 2014.10.07 20.23 in Family/Friends

Yesterday was the 6th of October, and I sort of missed it. It came and went and I didn’t really pay it any attention.

It was a fairly typical Monday, I had typical Monday things to do, and a small deadline that held my attention for most of the afternoon and early evening.

When the 6th of September came along, I was acutely aware of it. I knew it was the 6th. I knew the 6th was coming. The 6th of August started ok but then snuck up and caught me unawares, an emotional sneak attack.

This thing with the 6th started in July of course. The 6th of July was a terrible day, the culmination of a week and a half of terrible days.

Anyways, so yesterday marked 3 months. A quarter of a year. And it didn’t clue in, nothing really came up.

I guess this is that thing where time heals and all that stuff.

Thermostat Three

This might just be the fastest project I’ve ever done. Saturday morning I started the hardware build, by Saturday evening I had also begun the software. By Sunday afternoon I was halfway through. Sunday evening saw it 90% completed. Monday was finishing touches and adding some extras just because. Tuesday I finished it. This afternoon I installed it.

Some of the things that aren’t obvious in a still photo: The the block above the screen has two RGB LEDs behind it. These aren’t programmable, but one cycles through the colours slowly and the other does so quickly. Together they provide a sort of swirly multi-colour effect that I think is reminiscent of ST:ToS effects.

The red circle ‘red alert light’ is wired to the XBee’s RSSI so when the XBee receives a wireless command, the red light comes on for a few seconds.

The white gridded rectangle is the DHT22 sensor (temperature and humidity). I felt it would ‘blend in’ enough that it should be mounted right up front for all to see. The little black hole to the right of the DHT22 is for the light sensor.

Why is there a light sensor? Why not? Also: because I had an extra one laying around.

The screen display is mostly self-evident. Time, day, date. Heat/Cool. Run/Hold/Override. Target temp (small) and actual temp (large). Fan status (on/auto) and humidity.

The last line is EV (exposure value) and free memory. That’s 657 bytes. Not kB or MB, just bytes. It probably won’t ever change but it’s there just because there was space for it.

The following images have some more build details / information:

Two heads might be better than one – but three heads are way better than two!

Today, I converted my dual-head iMac into a triple-head iMac – one computer, three screens! And they’re all digital!

None of that shabby analog VGA stuff around here, no-sir-ee! The iMac screen is a Digital LCD, then to the right I have a 19″ 4:3 screen that’s running DVI, and up top I have a 19″ 16:9 HD-TV hooked up with HDMI.

I got the TV so I could watch the World Cup, and what with the football over for another 3 years 10 months, I wasn’t sure what to do with the TV. Then I realized hey, I could hook it to my iMac! Now I can play media up there, and it’s on one of those articulated arm things so I can swing it around and aim it at the living room.

Yeah, I’m in geek heaven here. Every additional screen you put on your computer is like eleventeen hundred geek bonus-points.
