The exhaust duct for the laser cutter is definitely not working. I am in sudoroom with someone who is cutting plain simple wood, and it's killing me. It's someone I invited to do the cutting so i'm putting up with it but I am eager to leave and get some fresh air. We definitely need to improve the ventilation situation somehow. 1. There is definitely leakage around the fan output, spraying smoke into the room before it even goes into the exhaust duct. It's basically a mass of duct tape … [View More]because someone who was very desperate to laser cut stuff to sell on the street wanted to just throw more tape at the job until it sort of worked. We need to measure the diameter of the fan output and the diameter of the duct, and buy the proper adaptor (or 3d print it???) 2. The exhaust duct has holes in it. They have been taped over and I don't feel any leaks there, but it's definitely something to look for and fix properly. 3. the interface of the duct to the hole through the skylight is suspect! It was installed by someone I personally know to sometimes half-ass things (me) and it has not been inspected since 2014. It's a 1/4" thick piece of wood that's simply pulled up against the skylight hole and could be leaking there. We need to go on the roof and check on that. 4. even if all the above are perfect, the smoke will be exiting just above the skylight and could be very well getting sucked back into the room from the top. We should build an exhaust stack a few feet high to make sure the fumes go...away. I would say that presently the laser cutter's exhaust is so insufficient that people should not be using it until it's fixed. -jake On Fri, 10 Jun 2022, Arthur Ulfeldt via sudo-discuss wrote: > this is a 12 inch plastic duct. it appears to be sufficiently attached. the > big hole in the side not notwithstanding ;) > non conductive ducts don't need grounding. > > On Fri, Jun 10, 2022 at 1:23 PM mark burdett <mfburdett(a)gmail.com> wrote: > >> I found some articles online about laser cutter exhaust and it says check >> the manufacturer's specs to make sure airflow and pressure is maintained >> (e.g. use 6" duct if it's too long for 4" to do the job).

wifi not working, new wifi access point in sudoroom

by Jake

tonight at sudoroom, i noticed that "the internet" was not working very well, and my phone was having trouble connecting at all to the wifi. And the signal strength was very weak. i tried "the internet" on the desktop computer on the 3d printer table, which is wired into the ethernet (doesn't use wifi) and since it seemed to work fine, i determined that something was wrong with the wifi. i tried power-cycling the ruckus wifi controller (singular rackmount unit that configures the many wifi … [View More]

Re: [omni-building] Omni Commons wifi not working

by danarauz＠gmail.com

Hello Folks, Sorry for the late reply, but it's been years now that I stay away from Google as much as I can. This address is no longer my main email address, so I don't check it that often. I could stop by tomorrow and see what I can do to get the WiFi going. Someone please Signal me the Network info (Network IP/Prefix, Gateway, DNS(s)). I don't have a card|key to access Omni; if the door is closed what should I do? I forgot the Sudomesh server area cage's lock code. :( I am assuming that … [View More]if cabling tools are needed I should find some there (in the cage), correct? I will be arriving there at about noon. Thanks, Daniel Google/Gmail makes me sick.

I would say if you are a CIS woman / minority do not join any working groups

by Romy Ilano

That was a great discussion! I love yar’s nuanced view too. But since I am pro woman I would say - if you are a woman, it’s probably best if you do -not- join a working group/committee or volunteer for stuff. You probably also are better off not doing anything related to teaching or education unless you really really want to. What the world needs is more smart women building projects and reaching the alpha states. Women and minorities carrying the unnecessary burden or making the world more … [View More]
