You could contact bobp@dogpatch.com. I'm sure there are laser job shops as well. The folks who sell one of the laser engraving machines (epilog or the like) have an office in bellevue, and do some work by the hour. I don't know how well their machine will *cut* as opposed to engrave. (And of course I cannot find their card right this second.) bmw -------------- next part -------------- An HTML attachment was scrubbed...

I picked this up at the dorkswap a few months ago, thinking I'd gut it and put something else in the case. I tried powering it up, though, and it seems to work perfectly, 3ns rise time (!) and all, except for its dangerously frayed power cord. I hate to destroy working equipment even if it is something that could probably be replaced by a single 74AC06. So if you want it, or just want the circuitry (it's got some toobs, and a heavy old transformer with the Tek logo on it, and a fan, and a double handful of discretes) send me a note.

We will have DJs, VJs, a bar, and one night only installations. Proceeds from bar and door cover (10$) to benefit 911 Media Arts Center. *Wear Electricity, and Bring a Robotic Date! * The exhibition opens Saturday, December 8, 2007 and closes January 11, 2008. *"Strange Things" web site:* http://dorkbot.org/dorkbotsea/events/pdstwe3/ *More About "Strange Things":* New and exciting genres of art emerge as artists, scientists and technologists bring together their expertise to push the boundaries of what is possible. Dorkbot-sea 's exhibition, People Doing Strange Things with Electricity, showcases innovative trends in modern art by bringing together established and emerging artists who work with electricity in a significant way either in their art, or in its creation. For the last show in 2005, over 1200 people visited the exhibit during the opening night event. Please see this pagefor an overview of our last exhibit including a list of artists, and here for pictures. This year, in addition to showcasing works that in some way involve the use of electricity, we are emphasizing interactivity: art installations that interact with the environment, with participant observers, and with other installations. " Strange Things" that pique curiosity and inspire a desire to touch. The Dorkbot Overlord Committee, with guest juror Misha Neininger, Executive Director of 911 Media Arts Center , selected over 25 pieces from regional artists. Our focus on interactive electronic projects encompasses a broad range of creative media: art that borders the line between physical and digital art, digital art and experimental media, kinetic sculpture, reactive sculpture, sound and light installations, web-based art, ubiquitous computing...to name a few. *Exhibiting artists:* Accelerator Group * Bill Beaty * Doug Bell * Joe Benner * Michele Boland * CCRT (LoVid & Douglas Repetto) * Rebecca Cummins * Scott David * Shannon Eakins * Leta Evaskus * Shelly Farnham * Stacey Farrar * Dan Greenberg * Eunsu Kang * Jeff Larson * Laura MacCary * Lawrence MacCary * Mark Malmberg * Marcell Marias * Mike McCracken * Eric McNeill * Chris O'Dowd * Toby Paddock & John Krug * Diana Vanderhoef * Rolf van Widenfelt * Xander * *Location* 911 Media Arts Center is located at 402 9th Avenue North at Harrison Street in South Lake Union.

This is RECYCLING, not donations - so if it's trash and it's computer parts, bring it on in. Accepted: - computers or anything that once was part of a computer - monitors - laptops - portable stuff like iPods - game consoles - peripherals of all sorts Not accepted: - home appliances - TVs - microwaves - livestock The first 500 people to drop off their junk will get a free compact fluorescent light bulb (ooooh!). This is a drive-through event (but if you haul junk down on a bicycle, you get a hi-five from me). Remember to wipe your hard drives, kids.

I thought this was an interesting piece of information to preserve so I started a dorkbotwiki page for things like this --- dork-friendly machinists, engravers, laser cutting shops, and so on. I couldn't think of a perfect name but I figured SeaWorkshops would be reasonably mnemonic: http://projects.dorkbot.org/dorkbot-wiki/SeaWorkshops > The folks who sell one of the laser engraving machines (epilog or > the like) have an office in bellevue, and do some work by the > hour.

Or any old- fashioned steel-and-grinder type machinists that have been good to work with?

It's fairly straightforward stuff: - The reception area ceiling is wired with conduit and outlets but it's not hooked up. - Hook up one set of trac lighting - Look into the possibility of having an isolated circuit in one of the rooms, for a piece with a large current draw Please let me know if you're interested in helping out on any of these. thanks...
