Drawn up through 459 now. Experimental “features” for 454 and 455 also complete. Looks pretty “sharp” according to a friend of mine.
So I’m actually writing this one up a bit early. During my friday CME session for that matter. This room is very stuffy and I fear I’ll fall asleep if I’m only paying attention. Paying attention can be quite the difficult task, as I’m sure we’ve all found out the hard way. Professor’s talking about fitting lines to scatter plots…
Ok so I hate like adhering to someone else’s eating schedule cuz I get hungry at rather arbitrary times. Eating on a cafeteria system can get annoying at times as I can’t just go and get snacks throughout the day as I usually would at home. So I bought snacks industrial quantities and set them in my room. This consists of lage amounts of goldfish and gatorade.
Now I can’t drink Gatorade unless I have ice and this still requires me to get out to the cafeteria, but the ice machine is open at more hours than the cafeteria itself. So that was great, but sometimes they turn off that ice machine. Only happened a few times now, but it’s annoying.
So I thought ok. I need to get my own ice somehow. Problem is, unlike dry foods like goldfish and power drinks like gatorade, ice doesn’t keep so well at room temperature. So what doo I need? A fridge. Duh. Where am I going to get that? Well, it’s no fun unless I build one.
Well, I haven’t actually build a fridge, but I’ve got a good idea as to how to go about it. There’s a thing called a thermoelectric cooler that works off something else called the Peltier effect. I don’t really have more than a broad idea of how it works, but what this thing does is move heat.
So we know that, given sufficient insulation around a given space, moving heat out of that space will lower the temperature. So we place our TEC in the walls of something like a foam box, add a few fatty heatsinks and a power source… and voila. Instant fridge.
And it shouldn’t be that much harder in practice than in theory; most components are premade for you. e TEC itself is widely available and many should be compatible with PC heatsinks. At the same time an old PC power supply should provide juice and the foam box is a joke.
Ok, well sometime when I’m not too lazy I’ll take a look at this. That’s all for now.
PS: I wanted to add that I usually update a bit earlier than J, but you’ll need to scroll up in the drop-down menu to see an early update on my half. So you can check that on a sunday or occasionally a saturday or friday and possibly expect to see an early update.
