Yet another week has passed. This week we've gotten some welding practice done by joining random bits of metal together into a little collective piece.

The space was open Tuesday, Wednesday and Thursday with fairly good attendance. Among …

Not much has happened in the space itself this week - we've mostly been "playing outside". A few of us were at Tvspelsjam, playing games and proselytizing a new game developer förening that Mika is setting up. Others were at Gräv 2014, informing and helping journalists with data security stuff so …

Jag (pettter) och MMN-o besöker i skrivande stund Föreningen Grävande Journalisters årliga seminarium Gräv. Gårdagens begivelser bestod i en gemensam föreläsning tillsammans med Sus Andersson (tack!), där vi pratade om källskydd och allmän datasäkerhet för journalister. Bland annat demonstrerades hur lätt fysisk access till en dator kan översättas till total …

Sunday roundup on a Monday, breaking my posting-on-the-proper-day streak (noo!)

First up recluster: lectus soldered a copper manifold for distributing water for cooling. The water cooling is important because server fans make too much noise for the cluster rack to be able to sit in a place where people actually …

More Sunday, more roundup.

Work on Recluster is moving along, with various pipe parts having arrived this week. I took a stab at fixing the broken bench power supply. There was an obvious problem with a blown capacitor, but sadly just replacing it wasn't enough to fix the broken channel …

We're now running the PuSHpress plugin on this Wordpress installation, so you can subscribe to us using PuSH (so far v0.3 of the specification).

This means our GNU social instance has received a bot which repeats posts from here over there!

New Sunday, new roundup.

The biggest news this week is that Academic Computer Club (ACC) donated some of their old servers for the recluster project. This is around 20 machines and a few disk servers in total. Pictures:

New week, new roundup.

Most of the activity this week revolved around recluster, mikael's low-cost cluster experiment. It seems powering it from a 12 V lead-acid battery works fine, as does the jury-rigged water cooling. Still plenty more to do on that front though.

Some more tools have been put …

This is the first post in a series of posts I plan on writing on Sundays documenting various goings-on in our space.

This week we were open to the public on Tuesday, Wednesday,  Thursday and Sunday, and I'd say average turnout was around six per day. We got a new …

We've suddenly collectively remembered that today is The Day We Fight Back, a global anti-surveillance protest event organized by the Electronic Frontier Foundation (EFF) among others. Umeå Hackerspace will be sending a delegation to the local charter of this protest. Sadly we've heard it's being organized via the greatest panopticon …

The site is being redesigned for a bit, but things should mostly be up and running again. In particular, we moved the "is the space open" functionality to the sidebar instead of it being part of the banner. Also things look generally much nicer :)

It is now possible to see whether the space is open based on the banner image on top of the site. Green LEDs = open!

The image is changed whenever the switch connected to the open sign is flipped, which may not be immediately obvious. We hope to make this more …

För några veckor sedan blev den åh-så-välkända och synliga öppetskylten för Umeå Hackerspace klar, med andra ord är det hög tid för en bloggpost om den. Skylten visar för folk utanför om någon är inne, och styrs från en liten manöverlåda inomhus. Lite bilder:

Manöverlådan lever inomhus.

Närbild. De tre …

So we tried Lost PLA casting with aluminum.

Step 1, printing a model.  We took this bust from Thingiverse and printed it at pretty good quality on our Ultimaker with pink PLA.

The print took about 3 hours.  Then we lowered this statue into plaster and let it set for …
