Tenging á Auber 2352 PID hitastýringu

Wednesday, May 31st, 2017

Ég hef verið að selja PID stýringar í versluninni minni í nokkur ár og fæ reglulega spurningar um hvernig er hægt að tengja hana.

Hér er ein leiðin. Skelli henni hér inn án frekar málalenginga.


Ef þú ert að búa til control box þá er sniðugt að bæta við rofum til að slökkva á stýringunni, rofa fyrir dælu og fleira, en flestir geta nú sennilega fundið út úr því. Ef ekki, þá ættir þú kannski að fá einhvern annan til að græja boxið fyrir þig 🙂

Vienna Session IPA

Wednesday, April 25th, 2012

I made this beer yesterday. Recipe courtesy of the mad fermentationist. I did a few small tweaks according to his tasting notes, and bumped the gravity and hops up just a tiny bit. I’m looking forward to trying this out.

OG was 1.042 and I mashed a tad colder than I originally planned, or around 66°C.

Recirculating the mash. These tiny pumps are awesome!

Hoisted the grains up and gave them a squeeze

And a beautiful sunset at the end of the brew day

Openoffice grab open, unsaved file from remote computer

Wednesday, April 6th, 2011

I just arrived home from my office and remembered that I forgot to save an open spreadsheet on my office computer (which runs ubuntu). I can access my office computer via ssh, but I do not have remote desktop access. I needed to access this document from home, so I started looking for the folder where openoffice keeps open, unsaved files. Openoffice saves all files you’re working for recovery in case openoffice or the computer crash while working on them.
So I sshed into my office computer, found a folder called /home/user/ and ran this command to find any openoffice files (hoping that would yield a recovery folder):
find . -name *.ods
This yielded a few results, most of which from this dir:
I checked the dir, and sure enough there was a file called untitled_0.ods, modified just a few hours ago.
A prompt copy from the backup folder to my Dropbox folder and it turns out this is the file I was looking for.
I love linux.

Kegerator build

Sunday, March 20th, 2011

Here’s my kegerator. I scored the refrigerator very cheap from a local classifieds site and the kegs and parts I got from I can see myself drinking a lot of beer the first days after getting this one into operation. One needs to be perfectly sure everything is in order! And what better way of making sure everything works than pouring a pint?

dd-wrt vs tomato

Thursday, June 24th, 2010

I tried dd-wrt for a few days on my asus rt-n16. My macbook and iphone had big troubles keeping a stable wifi connection to it.
However when I changed to tomato firmware I had no troubles whatsoever.
My vote: tomato.
