RIVETHEAD!

Wow, I feel like a true out and out rivethead tonight. I just spent the last hour filing, grinding, and wire brushing a 10″ x 20″ piece of 6061 aluminum alloy. See, when the G5 comes, it’s not going to fit on my shelf. Because of this I wanted to make a shelf for the G5, so it’ll sit nicely and look all pretty and stuff. My first choice was a nice 1/2″ thick piece of glass, but that ended up being too pricey; almost $70. Next, I consulted lowcostmetals.com after hearing about them from a friend. Turns out that I was able to get a appropriate sized piece of aluminum for $32, shipped. Not bad at all…

Anyway, the aluminum slab is a little scratched and was rather worn, so I decided to give it the most appropriate finish I could think of: brushed metal. Well, tonight I filed all the edges to nice 45°, put the wire wheel in my drill, and gave all the surfaces a fairly decent brush job, removing all but a couple of scratches. I think it looks pretty good…

As I was in the middle of finishing off the slab of aluminum, I remembered something I read online when reading the 6061 Aluminum Material Property Data Sheet. It seems that if one wishes to artificially age 6061 aluminum, it requires “350°F for 8 hours followed by air cooling” to reach T6 temper. Poking around Google, I found that T6 is a pretty hard temper, and I figured that it would be good to temper this stand, just to hopefully cut down on any more scratches.

So, in the oven it went. Seeing as this is a decent sized slab of metal, I’m going to give it 10 hours in a pre-heated oven. That means come 10:00am, I’m going to wake up, turn off the oven, and let the slab cool. Woo! Before placing the slab on the rack in the oven I made sure to wipe it down with isopropyl alcohol while wearing latex gloves. Hopefully that’ll eliminate any heat-assisted oxidation that may occur. If it does, I’ll just steel wool it off.

After the oven treatment I’m going to throw a number of coats of satin urethane (yes, the same stuff I used in my furniture) on the slab and call it done. Hopefully it’ll look nice… My tests with this urethane on various computer parts and metal pieces seemed to give a nice overall dulling, yet smoothing, effect, which is just what I’m looking for… So, we’ll see what happens. :)

Oh, maybe some pictures…

Well, just one, but that’s all right. I also put together the new table saw tonight, but I didn’t cut anything, so that part wasn’t as industrial as it could be… Woo! Italics…

Anyway, I think I’m done for tonight. I also slapped together some extra-low-cost shelves from Target to give me a place to put my vinyl and books in my office. Those worked out really well… Pics will be forthcoming, most likely after I get the office all put together. Finishing that will entail about two hours on my back, tying cables up above my head… Sort of the way I hurt my chest before. Sort of.

Yay! I stopped at Sears Hardware on the way home and I *finally* have a Vernier caliper. With me being as anal as I am about things being accurate, I can’t believe that I never had one. Now I can finally measure things accurately. No more silly tape measure trying to determine if something is 7/16″ or 3/4″. Heh.

So, it turns out that the D-Link DWL-520 I won on eBay is actually the DWL-520c, which does not have the Prism2.5 chipset on it. See, I want a card with the Prism2 or Prism2.5 chipset, because then I can run it in hostap mode and have it be the 802.11b access point for my network. Nice idea, eh? wi0 on the firewall is a real interface and the access point and all…

But no…

Yet another thing that I try to do that I fsck up.

Gah.

On a side note, anyone interested in a good deal on a PCI-based 802.11b card? It’ll work great under Windows, just not OpenBSD.

Desk!

This weekend I picked up a new desk for my office. My old one was kinda small, and just didn’t have the writing surface area that I needed. Well, I get the new desk, the O’Sullivan Diplomat from Staples, negotiated down to $109.99. Well, I get it home, get it set up, and while it’s nice and all, there is a decent sized gouge in the top left desk piece. No big deal, but I decide to call O’Sullivan anyway, just to see what they can do.

Well, the end result of everything was O’Sullivan sending me, free of charge, a whole new top piece for the desk. There must be an absolutely massive mark-up on these desks if they can afford to ship a 2′ x 3′ desk piece so that it will arrive “within a couple of days”, to everyone who calls and asks for one.

Weird…

Well, it seems that if you take 6061 Aluminum and heat it to 350°F for 8 hours, then air cool it, it will be hardened to T6 specifications. Once I get the stand shaped as I want, I think I’m going to try to temper it in my oven. I can’t see any reason why it’ll cause any problems, and the chemistry of 6061 doesn’t seem like it contains anything that would be harmful to have heated up in my house.

Pan 0.14.0

In case anyone cares, I just installed Pan 0.14.0 from Fink unstable. It’s far improved over 0.13.2 (or whatever) which is the version in stable. I highly recommend to anyone needing a USENET reader that they check out Pan. Install X11, install Fink, make it work with unstable (check the FAQ), and install. It’s very, very close to Forte Agent, except it defaults to viewing images internally. The speed is great even on my G4 Cube.

Oh, I’ll have a G4 Cube for sale in October if anyone is interested.

mmm…..meat!

posted this in his journal the other day, but the site that hosted it got hammered rather quickly. Well, thanks to Jeff and Joy, it’s back. Presenting the 20 x 20!!! It’s a In-and-Out burger with 20, yes 20, slices of beef paired with 20 matching slices of cheese. Lettuce, tomato, and mayo, on a warm, soft bun. And this kid eats it! It’s amazing… I’ve never seen anything like it in my life. Huge props go out to JwAgMaN1 (via AIM) who ate his creation, the 20 x 20. Oh, I guess a preview picture would be nice, eh? Well, sorry… no decent sized thumbnail readily available. You’ll just have to go to the site.

Does anyone who reads my journal have any experience doing GIS work? I need to make a map of Mackinac Island for this week. I think the maps are available from the state for free in electronic format, I’m just having trouble figuring out where to go from there.

Okay, so tonight I managed to smoke my GPS. The cable is made per the published pinouts as well as those found online in various places. I hook the GPS up to the car for power, it lights up, and slowly gets warm. Peering inside, one of the ICs now has a smallish hole in it. Suck. The power was obviously hooked up correctly, as it lit up. The voltage specified for it is 10v to 35v (or something like that) so that’s right. I guess it’s time to buy a new GPS. There’s another $70 down the hole. Suck. I did manage to find a 6.4GB hard drive for my grandparents computer. That means I can take the 120GB that I got from Best Buy back and save a bit of money.

This is just getting frustrating. I do things right and they blow up in my face. Ah well.

Ahh… New Klipsch ProMedia 2.1 speakers came today. I’ve now replaced my older Altec Lansings from 1995. The ALs were really, really nice, better than most other speakers, but they had a bad 60Hz buzz coming from the subwoofer. I got these speakers as refurbs for $99 for the pair, with sub. They retail for $179 – $199. Not a bad deal… I’ve only had two problems. First, they forgot to ship the speaker cables with them. A phone call later and they are on their way. I’d been wanting to make some custom 16 gauge cables for them anyway, so I got out two 3.5mm mono plugs (yes, the back of the speaker accepts 3.5mm plugs for the amped signal, for some unknown reason…) and the speaker wire, then made up the connectors. I thought about putting six-way binding posts on the back of each speaker, but I can probably leave this work for another day. If it’s even worth it… Anyway, I hook everything up and they sounded like shite. After some troubleshooting it looks like there might be a problem with the input line, some wiggling around in the iMic (USB sound device for the G4 Cube) and everything is good. These speakers sound real, real nice. Definitely worth $99 for the pair. Now I only need to rearrange the office… And find a new place to mount the iSight, as it had sat on top of the old speaker.
