OMNI Hackathon today - tomorrow (Sat/Sun)

by Matthew Senate

See the Agenda here: http://wiki.omni-oakland.org/w/Event:2014/05/03_Omni_Hackathon I'm bringing Sudo Mate, bananas, and apples for breakfast. I plan to brew coffee in the percolator at 2141 broadway. I'm also bringing two pastas, beet greens, and roasted beets for the pot luck lunch. Can anyone bring some carbonated water for the sudo mate? Extra sticky pads and markers (dry-erase AND permanent) would be invaluable! // Matt p.s. here's a static copy of the agenda as of the time I sent this email: Saturday - *10am*: Begin, light breakfast and coffee, start to add topics/projects to wall. - *11am*: Commencement Ceremony, Announcements, Agenda-setting - *12:30pm*: Pot-luck Lunch - *1pm - 5pm*: Break-out Sessions - Sessions should last around 30 min - 1 hour, have a note-taker (posting to wiki), and one person to plan to report back at the end of the day. - *5:30pm - 6:30pm*: Report-Back Sunday - *10am*: Begin again, light breakfast and coffee, start to revisit topics/projects on wall, notes on wiki, etc. - *11am - 12:30pm*: Break-out Sessions - *12:30pm*: Pot-luck Lunch - *1pm - 4pm*: Break-out Sessions - 3pm: Hacker Spa Mtg @ Arbor Cafe - *4:30pm - 5:30pm*: Report-Back

omni.

by David Keenan

Hello everyone, If you are interested about what's up with Omni, I suggest you come to the hackathon tomorrow, as Matt said: http://wiki.omni-oakland.org/w/Event:2014/05/03_Omni_Hackathon INFOS WILL BE LIBERATED PROMPTLY AT 11AM ON THE DOT. "Doors" open at 10am with breakfast and coffee. Contact Matt Senate if you wanna help setup. Highly suggest Bring coffee (coffee grounds are best, one of the big containers), donuts, bagels, etc. We got our work cut out for us.. Suggest those with inquiring minds attend. Please? Because we need you. Now. So much love! David

lulzbot TAZ 3d printer is dead

by Jake

so i spent all evening (and some of last night) to finally spool up the gigantic pile of black filament for the TAZ 3D printer. i finally got it hung from the wall with a dust cover over it and ready to feed smoothly into the printer, and then i discovered that the heating element in its extruder head is dead. oh well. so, we need a new resistor to go in there. I don't know what the original spec is, but since the whole thing runs on 24VDC and assuming 24 watts of heat, that would be a 24 ohm resistor or so. Is someone other than me interested in contacting Lulzbot and asking whether they want to send us a new resistor, or if they can tell us what part number of resistor we should get as a replacement? -jake P.S. yes i tested the resistor and it's dead, infinite ohms, it's burned out. When we get a replacement we can glue it in there better than they apparently did. If the glue goes bad it dies.
