Hi all,
If you have borrowed any of the microscope objectives or eyepiece lenses
from CCL, please return them as soon as possible.
If you see any microscopes sitting out, that is likely because they are in
use on a regular basis, and they will be sorely missed if not in working
order! Please don't remove parts from lab equipment without checking with
someone first.
So, please return our lenses - no questions asked. We have a pretty good
idea exactly when they disappeared, but we'd rather not have to do the
detective work to figure out who was where when. Let alone having to
install cameras or lock up all of our lab gear, which defeats the purpose
of having a community lab.
Thanks!
Patrik
It turns out that sudo room suddenly has $8,600 in bitcoin!
How did this happen? I don't know!
I think we should immediately sell at least enough to pay our debt to Omni.
Any sudo members who think we shouldn't just sell every single bitcoin
right now while the price is high?

Excellent location and quiet spaces. Across the street from OSH Hardware
and Berkeley Bowl West, and on the same block as Discount Fabrics, The
Shipyard and Urban Ore, as well as easy street parking and access from
I-80. Safe industrial west Berkeley neighborhood right on the border with
Emeryville and Oakland.
Ideal uses are art, electronics, office, etc. No heavy fabrication please,
but light is ok. We want to avoid anything creating lots of noise or
fumes. Optional access to large open 2-story area for occasional projects
with loading dock. We have blazing-fast gigabit internet with symmetrical
pipes, so can be a good choice for big data, such as video production. 24
hour access permitted, but must respect nighttime quiet. Living in either
space definitely not permitted.
First space is semi-open 21' x 13' with 2-story ceiling and large amount of
natural light. Has existing workbench and plenty of power (240v/120v). $390
/ month including utilities (reasonable electrical use, internet, trash).
(Surfboards not included!)
Second space is 18' x 15' in a very private location on the second floor.
Has openable window overlooking Ashby. Only 120v electrical. $490 / month
including utilities (reasonable electrical use, internet, trash). The desk
and drafting table pictured are included, but can be removed if
desired. (sorry,
the dressers are not included).
Please email for details or to arrange a visit!
…Where the adhesive is conductive. I just need to have a small piece. I
have some on order but have a time pressed project I want to move forward
on.
Thanks,
Cere

does anyone on this list have a solenoid? something that can pull a pound or
two of force, from a distance of 1/4" or more, ideally. 12-24 volts would be
great, although we could do 120V if necessary.
thank you

here's the repo:
https://github.com/sudoroom/Marlin/tree/quickcircuit
marlin can be uploaded with regular arduino, it's an arduino mega 2560
we still need to enter the correct values for stuff like
DEFAULT_AXIS_STEPS_PER_UNIT
DEFAULT_MAX_FEEDRATE
DEFAULT_MAX_ACCELERATION
although really only the first one is necessary.
then we need to either find a solenoid or use this servo to do the Z axis, and
configure marlin to control it appropriately from a Z command or whatever Z
instruction gets produced by stuff like PCB2GCODE

I'm starting to play around with electrowetting (specifically the OpenDrop)
and I'm having trouble finding a source for extruded ETFE film of a
thickness of at most 50 micrometer.
Any ideas?
Anyone have experience with ultra hydrophobic coatings or spin coating?
