Anyone want to participate in a read aloud of One Hundred Years of Solitude? Readers would alternate chapters over a couple days, although just listeners are welcome. The book is amazing! My schedule is open Tue and Wed. Rock

Re: [sudo-discuss] Sudouino328 PCB Design

by Hol Gaskill

Hey Jake, No FTDI chip onboard for this one, just shown on the attachment to help lay out the connections which are 6-pin TTL serial. I'd like to keep everything through-hole for the first sudouino so it can work as a kit for newbies, and since I personally don't even know how to SMD solder, all the work done on it so far assumes no SMD components. I remember encouraging you a few weeks ago to take the lead for the sudouino 2 board around the ATMega32U4 as you've suggested using this chip previously. I think there are many cool things that can be done with it, so I look forward to seeing what you come up with to accompany that chip. In the meantime I'll continue work with the 328p as planned in order to bring this board online as soon as possible. As far as connectors, I probably won't use any myself and I think we should sell some boards without them. I do agree with Steve on having an option for screw terminals for the switched loads, and either a screw terminal or a barrel jack for DC power input to the board. Whatever we think would be the most popular, I'll space the holes accordingly so the PCB design will accommodate either way. So it looks like we're up to 8+ different packages based on 3 different choices - 3,3V / 5V, kit / pre-assembled, bare holes / terminals. What kind of connectors would the most people use for power in and out?

Sudouino328 PCB Design

by Hol Gaskill

Hi Folks, Almost done w/ PCB design. That's an ATMega328p processor and a ULN2003 for power output up to 3.5 amps out of the box. Still need to add some connectors for I2C and 12V, 5V. I usually use SAE connectors http://www.vetco.net/catalog/images/G-QD-10-2.jpg for my 12V loads but we could solder on a barrel jack, or just ship it with holes for DIY soldering of connectors. Suggestions? Cheers, Hol

sudoroom 3D printer back online!

by Jake

last night I replaced the hotend on the sudoroom type-a-machine 3d printer. after that i spent a bit of time attempting to print and kept running into problems, which i'll list. it seems that some of the PLA we have that came from type A machines is clearly labeled to be printed at 190-220 degrees! I have always used 185, but i guess this is a new formula. When i set it to 205 it still seemed too cold, so i ended up using 220. You should set the temperature in the slic3r before you export your gcode. There are other ways to do it, but if you know them you don't need me to tell you. the other issue is that our spools of filament are dusty! it's gross. And all that dust goes into the extruder and jams it up. The nozzle is only 0.35mm diameter! so clean the filament spool first (DO NOT GET PLA WET) and keep a dust-catcher on the filament before it goes into the machine. I put one on there last night. something like this would be fine, if we had the right foam, but for now i just cut some acrylic fabric and wrapped it around the filament with some copper wire to hold it on there. It should work but check it once in a while, or when changing spools. someone had put tape over the old tape on the platform in a very chaotic and haphazard way. Also there were a few melted spots on the platform where a hot extruder had been rammed into the platform and created a little vulcano. I carved the raised spots off the platform with a flat-edged blade, leveling them off, and then i re-arranged the tape properly so there is NO OVERLAPPING OF TAPE and only one layer of tape. It is necessary to maintain the platform any time you're trying to print if it is not already good to go. I didn't re-level the platform so if someone else wants to do that go ahead. It seemed a bit higher on the left than on the right. I like to get a perfectly cylindrical object and adjust the z-height so it just barely rolls under the extruder tip, and then try in four corners of the platform to compare the height. now join the sudo-prints mailing list! http://lists.sudoroom.org/listinfo/sudo-prints -jake

sudoroom mailinglist just for printers!

by Jake

Sudoroom has so many printers, it's hard to keep track! 2D printers, 3D printers, label printers, and even screenprinters! there's some sort of weird flyer-duplicating machine that makes only green ink but is really cheap to use, there's that new fancy COLOR laser printer... so here is a new list, sudo-prints(a)lists.sudoroom.org if you know how to use one of the printers at sudoroom, including the CNC machine (hey it can print in wood) please subscribe to this list! then we can put labels on all the sudo printers that say "have questions about using this machine? noticed something you think others should know? do you know how to use it and want to help others? write to sudo-prints(a)lists.sudoroom.org !!!" your present for joining this list is that you get to hear about the sudoroom 3d printer, latest news, a post that i will write right now. -jake

Re: [sudo-discuss] Sudouino328 PCB Design

by Jake

Hi Hol, I have lots of opinions and advice about this design, but i would like more info about the state of the project first. For example i am curious whether this thing will have a USB port or use the 6-pin serial header like a Boarduino. I have a bunch of Atmega32U4 chips that you can use for this project. True that they are surfacemount but it's not harder to do than through-hole, in fact it can be much easier even for newbies. I have syringes of solder paste, although it can be done with regular solder easily. here's a video of someone doing it with hot air (note: they fool around with the narrow stream of hot air, but you can just do it in a blast with a regular hotair gun in much less time) http://www.youtube.com/watch?feature=player_detailpage&v=2Z7nCAxS2Rg#t=548 the nice thing about the atmega32U4 chips (besides the fact that I will donate them to the project for free) is that they have native USB, which means your boards can plug straight into a computer like an arduino leonardo. Also they will be able to pretend to be other devices, like a keyboard, mouse, printer, disk, or whatever you want. specifically about the SAE connectors, I am against them. I think the board should just have 1/8" holes for wires to be soldered into. -jake Hol wrote: Almost done w/ PCB design.

Fwd: hackerspace burn-out

by Chris Bee

---------- Forwarded message ---------- From: Chris Bee <hotelcompany(a)gmail.com> Date: Sun, Dec 22, 2013 at 12:03 AM Subject: Re: [sudo-discuss] hackerspace burn-out To: Romy Snowyla <romy(a)snowyla.com> I agree with everything on that list, and speaking for myself I think I deal with those issues well enough...I'm pretty good at compartmentalization, and can recognize when the issue lies within me and not assign blame or heat where it's neither needed nor warranted. But... I'd like to add "failure to grasp or acknowledge the DIY aspect of hackerspaces." This is directed towards people (NOT sudoers) who seem to regard sudo as a go-to for broken shit that they have no intention of fixing themselves...I don't mind helping people as long as a) they want to be involved with the process of getting their gear working again and b) don't expect me to put whatever I'm doing at the moment on hold to give them my undivided attention. This has probably happened to all of us at one point or another...I'm getting better at setting boundaries but sometimes I feel like I have to be short with people who I really don't want to alienate but who simply aren't going to get the message any other way. One thing I've started doing is wearing a large pair of headphones, which is a cue I picked up from juul....if that doesn't send a clear signal that "I'm here temporally but somewhere else psychically" then I figure it's okay for me to let whoever is trying to drag me into their project what's really going on. -chrisbee On Tue, Dec 17, 2013 at 5:30 PM, Romy Snowyla <romy(a)snowyla.com> wrote: > Unrealistic expectations > One bad evening improperly distorting perception of hackerspace as a whole > Lack of sleep > Unrealistic understanding of basic human social dynamics > Personal conflicts > > > Sent from my iPhone > > On Dec 17, 2013, at 2:23 PM, Craig Rouskey <craigrouskey(a)gmail.com> wrote: > > What are the causes of burnout? > > > On Tue, Dec 17, 2013 at 2:08 PM, Romy Ilano <romy(a)snowyla.com> wrote: > >> we all go through cycles of hackerspace burn out. >> >> would it be nice to have a 2 minute therapy session on dealing with it? >> my hackerspace burn out cycles follow my life.

New sudoroom t shirt test (color from on demand start up zazzle)

by Romy Snowyla

Hi I got the new test sudoroom zazzle shirt. It was about $24 Advantages Looks nice People can choose the exact color fit and style - huge problem for small people like me since most shirts are too big Fast! I got this up and printed in a week with minimal time and effort I didn't have to put any up front costs and I'm broke so that's nice We don't have to deal with shipping or inventory Disadvantages Very small profit for sudoroom : we'd make $2-3 a shirt Tied to a commercial service T shirts are all new and cost $20-30 So we can't use used clothes stencils or mass producs on cheap $2 a pop hanes shirts It's not silkscreen Sent from my iPhone
