It is HOT!

So I fixed my air conditioner blower motor, but now my AC is low (or out) of freon - ergo it is HOT. I do have a small window unit in my bedroom so at least I have one nice and cool room in the house. It started me thinking though. We haven't always had AC, some people didn't even have ice back in the day! What would I do if I didn't have ice water? I mean, is it just one of those things that if you don't know any better then you are fine, but once you know that there is more out there you won't be satisfied with less? I guess there are a lot of things like that. I would hate to have to live without internet now. And a DVR, what about a car? It all makes me start thinking . . .

Anyway, now that I am on a technology train of thought, let me tell you about some of our newest additions in Bogard. From the very beginning of working at Tech, I have wanted to be involved in teaching (and doing) design work. Not your typical number crunching design work, but more of the "why don't we do something completely new" type of design work. So I have worked my way into a position where I get to teach an open ended, multidisciplinary design class and it is great (IMO). I am going to have to spend some more time this year working on the actual design (pun intended) of the course, but at least the framework is in place. So as part of this position, I get to seek funding for a prototyping lab, and we have been really successful lately and have added a rapid prototyping machine that I blogged about a long time ago, but since then we have gotten a water jet cutter, we have some CNC lathes and mills, a laser scanner, a powder coating machine, a vinyl sticker printer (you know, for making it look good), and a bunch of tools. We are getting to the point that we can make just about anything - which will come in handy this next year as we begin work on our new eco cars.


Last year (I tend to speak in school years, so bear with me) we built the "Blue Diamond" and carried it out to California to compete in the Shell EcoMarathon. We did ok, and got a lot of good publicity. This year, we are going to make some modifications on this car and re-enter it. But we are also going to build a completely new car to enter in the "Urban Concept" category. This new car will have to be much more car like - headlights, four wheels, room for two . . . I think it will be a lot of fun, err I mean a good teaching tool.

I like what I do! I just wish I fixed AC's, hmm maybe I can . . .

The Saints are Winners!

Oh Happy Day! The Saints will now officially have a winning record this year. Not only that, but they should make the playoffs. Who knows, they may even have a first round bye. We will just have to wait and see. It is amazing what a difference a year makes (and a new set of players and coaches.) Speaking of coaches, you have surely heard the Tech no longer has a football head coach. I have heard several names mentioned to replace Jack, some of them are very exciting and others are pretty depressing. We will have to wait and see how that turns out too. The plan is to have a new coach by this Friday (Dec 15th), but I don't see that happening. My inside sources tell me, that . . . well . . . they don't really tell me anything useful.

Due to the overwhelming response (at least one response already!) to my technical post (see below) I have decided to post another technology based item here. (I hope the sarcasm came across well). So basically I get to play with . . . I mean research . . . cool technolgy every day and right now I am working with some fuel cells. This particular project is less research and more trying to put together some projects for a high school engineering exploration thing we are doing. Anyway, I am building a fuel cell powered car (a small one, only about 10 inches long). You can see a picture to the right. Oh and check out the cool Louisiana Tech University ruler (it has both metric and US customary units on it). So I am sure you are thinking that I am really cool right about now so let me take advantage of this moment to explain a little about the fuel cell. Basically, the fuel cell combines hydrogen atoms (which are a proton and an electron) with oxygen atoms to make water (H2O). The trick is that the hydrogen electrons are stripped off and have to travel around a circuit to get to the other side of the fuel cell in order to combine with the hydrogen proton and the oxygen. And, well, an electron traveling in a circuit is an electric current. I am using that electric current to run the motor of the car. Here is a closer view of the actual fuel cell and the tanks. The tanks hold the oxygen and the hydrogen (and water too). Pretty cool, huh? Hello? Anyone there?

Technology

So I said I was going to post a little bit about my new office toy. I had almost let the day go by without posting it, but I remembered just in time. My new toy is a Dimension SST 1200. It is one of the coolest machines ever, it is a 3D printer. It can actually print three-dimensional objects. I can create a computer model of anything and send it to the printer and it will print out a plastic copy of whatever I created. Pretty cool, huh? Well, I think so anyway. We use it for creating prototypes and such. For instance, one of my co-workers was working on an directional drilling machine and we printed out the parts he designed and he can used them to show the clients what ideas he has come up with so far. I have a picture of it here, it is basically a big gray box with some cool technology inside. The other picture shows some of the parts I have printed out. I can't show the directional drill parts (they are secret for the time being) but they are pretty cool too.
