Name that Ware August 2006

Friday, August 25th, 2006

The ware for August, 2006 is below. Click on the pictures for a much larger version.

I try hard never to post a ware that people will never have seen by definition–e.g., wares that I make. However, I’m going to make an exception this time, because there is an interesting story behind this one. Perhaps of most interest to readers is that this ware will be open-sourced and soon schematics, layouts, and software development kits will be released. So, I guess the question to readers is: what might this do? What is it for? This will be a lightning competition this time, I think, because in a few days my day-job company that I made these for will allow me to make public the details about this hardware.

Winner of Name that Ware July 2006!

So the winner of July’s name that ware is Joe Martin, congrats! Please contact me for your prize. I think Joe’s explanation was the most informative, pointing out how the channels were routed in lexan and bonded together. I still don’t know definitively what this ware is, but the little poking around I did agree with the idea that this is used mostly in dangerous settings, such as nuclear reactors or in the presence of highly unstable chemicals like silane. And yes, I’m “that guy” who bought it from Halted specialties :-D I had read about pneumatic logic before, but I had never seen one in real life, so I was really excited to see it on the shelf. I just had to get it to add to my collection of weird and wonderful electronic artifacts. I’m surprised that people recognized it from seeing it there on the shelf!

Winner of Name that Ware June 2006!

Friday, August 25th, 2006

Wow, a lot of people had very good answers for this one. It was hard to choose one, but I’d have to say Mark wins the prize this time. He managed to guess the manufacture and the model, which is the RMX 1450. Congratulations, and great work! Contact me to collect your prize. This is the amplifier that I use to drive my Bose 802’s, part of my DJ rig, which I haven’t had a lot of time to play with lately, unfortunately.
Short on time just now for writing a post, but basically, the reason why I had my amplifier open was to replace the cooling fan for the big heat sink bank. Since it’s an audio amp, it’s no good to have a noisy dust-laden fan blowing through it, so I replaced it with a nice new hydrowave bearing fan from Panasonic.

There’s an ORCA in my livingroom!

More posts to come in a couple of days–need to announce winners of name that ware and throw up a new ware–but in the meantime, more fun stuff to talk about.

Last month I had the priviledge of hosting the MIT ORCA team at my place–and at the complex’s swimming pool–for an evening while they worked on debugging their autonomous underwater submarine. Their machine is a fine piece of engineering, I think–it has come a long way. I used to be on the MIT ORCA team for the first five or so years, and they are now on their 9th year. Check it out:

Yep, just about everything you see in there is custom-built, cut, or welded–probably the only stock part is the PC104 core as far as I can tell. A pretty impressive amount of electronics in a tiny space. They even have flashing blue running lights that look pretty snazzy, and they have a neat little waterproofed wifi dongle that they float on the water surface that they use for debugging the unit with a shore box while it is submerged. And yes, it is still running linux.

Alternative Freedom (Again)

Wednesday, August 23rd, 2006

Since I’m updating my blog, I promised the swell producers of Alternative Freedom (a documentary about the invisible war on culture), that I’d put a plug for them here…their movie, which finally got a screening in New York, is now available for purchase online. $1 of every purchase goes to the EFF!
