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.

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?
Cheers,
Hol

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,

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 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.

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.

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.

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
