fyi: Little Box Challenge: Build A Smaller Inverter

by Phil Wolff

https://www.littleboxchallenge.com/ is offering $1,000,000 to the team that designs and builds the smallest inverter. Is there a sudoer contingent interested in forming a team to explore the barriers to making inverters smaller? What the inverter needs to do > > The winning inverter will be the one that achieves the highest power > density and meeting a list of other specifications, as determined by a > panel of judges, while undergoing testing for 100 hours. > > In brief, the other specifications are : > > - Must be able to handle up to 2 kVA loads > - Must achieve a power density of equal to or greater than 50 W/in3 > - Must be able to handle loads with power factors from 0.7–1, leading > and lagging in an islanded mode > - Must be in a rectangular metal enclosure of no more than 40 in3 > - Will be taking in 450 V DC power in series with a 10 Ω resistor > - Must output 240 V, 60 Hz AC single phase power > - Must have a total harmonic distortion + noise on both voltage and > current of < 5% > - Must have an input ripple current of < 20% > - Must have an input ripple voltage of < 3% > - Must have a DC-AC efficiency of greater than 95% > - Must maintain a temperature of no more than 60°C during operation > everywhere on the outside of the device that can be touched. > - Must conform to Electromagnetic Compliance standards as set out in > FCC Part 15 B > - Can not use any external source of cooling (e.g. water) other than > air > - Does not require galvanic isolation > > Our testing philosophy is to not look inside the box.

ServerRoom Update: July 21, 2014 11:37PM

by Somebody

Awesomeness: Thanks David K, David ?, Jeremy, and Sally for your help. That was a lot of stuff!! The area got 96% cleared up. We moved the 2 Two Posts Racks, and the improvised server cart holding three two Servers and a Dell Desktop. If someone could clear up the rest of the stuff would super! What is left? A black big cabinet, and miscellaneous stuff left on and around the shelf. Many Thanks! p.s. staged-photo ;) hehe

Server Room Update July 21, 2014: Donation via Chris, Screws + Cage Nuts + Server Rack Status

by Somebody

Hello All, Just we all know: DONATION RECEIVED: We have received a donation of 2 Two Post Racks. Thanks Chris!! The donation easily saved us about 400 dollars. We only needed one for production, but Jeremy and I already have discussed how we can use the second one (training for those who would like to learn how to reset passwords, erase config files, and or do OS upgrade on the spare Cisco Switches that we have. :) -Oh yeah... we couldn't wait and installed a couple of switches on one of the racks! :) SCREWS AND CAGE NUTS: Anyhow: for those that know how messy can get with having the wrong kind of screws and cage nuts: We have narrow it down to have the donated racks tread as a model to use for the Server Rack square holes. So when we trying to install a switch or rack mount server/device we won't go bunkers trying to figure out what screws should be use. The screws we are using are 12-24. SERVER RACK STATUS: And talking about the Server Rack.... Last Friday I checked with the Vendor and I am glad I did. There was some wrong info in the billing part of the order, it did get corrected then. So now that detail got cleared up, the estimate shipping date is August 16. Yes, until then since this is a back-order. Thanks! Daniel

We have internet!

by Jeremy Entwistle

In the morning at&t was at the omni, they were chopping the tree across the street and preparing the phone line for sonic. They eventually installed two panels with lines going to the landlord and us. The line to us was marked as *sonic cir 319* and *sonic cir 320*, but nothing was setup. Then we wired it and... we have internet!

SERVER ROOM UPDATE JULY 21, 2014: We got a place!

by Somebody

SERVER ROOM UPDATE JULY 21, 2014 Hello all, We finally concluded that the small stage that oversees the Sudoroom is where we'll put the Server Room. Yes, the area behind the SudoRoom sign. This particular area is full of wood and other stuff that needs to move, so if you feel helping on this part of Sudo Reboot, please do. If you have any questions or need more info on how to help please check with Marc, David, Daniel, or Jeremy. Thank you!

Fwd: scissor lifts

by David Keenan

what are sudoer's thoughts on scissor lifts, rental vs. purchase..? ---------- Forwarded message ---------- From: David Keenan <dkeenan44(a)gmail.com> Date: Mon, Jul 21, 2014 at 1:19 AM Subject: scissor lifts To: "omnilogistics(a)lists.riseup.net" <omnilogistics(a)lists.riseup.net> Hi all.. um - Thinking about all we have to do and talking with contractors - I think we will either have to rent or, maybe, purchase a used scissor lift for all we have to do. Looks we can rent for ~400-$700/mo, or buy one for ~$4500-$6000. Advantage of buying one use is obviously, we keep it as long as we need and when we are done (if nothing breaks) we just sell it for about what we bought it for, which will be cheaper than renting. We have these 'get up high' tasks - some necessary, some potentially necessary: Ballroom: - Ceiling tiles: these are falling off/down, some water damaged - fix, remove or replace - Soundproofing (as per a studio engineer I took through the place): Pexiglass or similar under the skylights, and some sort of closeable/openable cover for the 2 large pull fans (ie large openings from which most of the sound escapes into the neighborhood). This will be necessary for any future cabaret license.. and we need to start renting that ballroom. Barroom: - Ceiling tiles & florescents: remove - New ceiling lighting & eletrical conduit: install Sudo/CCL room: - Pull fans to install in skylight vents - peeling paint & superficial damage to fix in ceiling (as per CCL's need for cleanliness) Exterior: - Siding on south wall: fix up and/or or replace damaged / rotting boards before rainy season (Landlord may pay for some of this) Potentially necessary everywhere: - SPRINKLERS aaaaaaahhhhh - this will make it far less expensive / scary an investment. If we bought a used lift, we could start installing it room by room and take our time. - Fixing any elctrical, gas or plumbing pipe high up that is hard to reach An added possible benefit marc brought up - if we kept it - this would aid greatly in Mesh installs around oakland.. maybe mesh could help out with the purchase, and it could be taken on field trips..? Mesh - what say you..? Best, David

Re: [sudo-discuss] SONIC.NET CANNOT GET INTO OMNI - ANYONE THERE?

by David Keenan

Extension 1 for sales, tech is Keshon - if anyone needs to communicate with them They were let in finally by John thank goodness - It would still be good if someone was there - the tech needs to try to improve the bandwidth. If someone could roll over and assist the tech, that would be good? - I did confirm that at least on paper we are connected to the close C.O. (~1.1K ft away), so we should be getting close to the provisioned bandwidth of 100Mb down / 20Mb up, instead of 20/1.5 as we are currently getting - Tech should be told to try the Tace 5168 Sonic is providing so our Zyxel modem is not blamed / the culprit - Sonic's Tace modem should be hooked up right at the MPOE (in the utility room) to remove any variables possibly related to faulty inside wiring - Tech should probably be told to look for undocumented bridge taps (i.e. at the nearest b-box outside) to see what may be dragging down the bandwidth Best, David On Sun, Jul 20, 2014 at 11:28 AM, Jenny Ryan <tunabananas(a)gmail.com> wrote: > An extension would be helpful!
