  • Export data from Xively to CSV

    I’ve been using Xively (back then it was Cosm) for my data logging Arduinos since 2012, so when they announced that “LogMeIn has made the decision to retire Xively Personal from its current line of products effective January 15, 2018 at 12:00PM ET“, I thought I’d better get my data out of there. Unfortunately it […]

  • Logging statistics from a power meter with an Arduino and a LDR

    Logging statistics from a power meter with an Arduino and a LDR

    My electrical power meter has a pale yellow LED that flashes once for ever watt hour used. Inspired by power.labitat.dk, jespereklund.blogspot.com/2011/10/elmaler-overvagning-med-arduino.html and other projects, I set out to count the flashes with an Arduino and output some nice graphs showing my electricity consumption. I wanted to use an LDR (LDR’s on Amazon) to “see” the flashing LED […]

  • Dual booting Android (Jellybean) and Linux (Ubuntu) on the Asus Eee Pad Transformer (TF101)

    Dual booting Android (Jellybean) and Linux (Ubuntu) on the Asus Eee Pad Transformer (TF101)

    These are my own notes, so I have a chance of remembering how to do this 🙂 First of all BACKUP EVERYTHING!!! I use Titanium Backup Pro (and buy the pro key), and backup everything to an miniSD card, that way the apps and userdata can be restored in the new android rom (even if […]

  • Logging system stats from NAS to Cosm.com

    Cosm.com (formerly Pachube) is an online database that lets you store values and plot them over time. One use is to log system stats from a computer or NAS (in this case a Qnap 419p). First setup an account on Cosm and add a new Feed, this will give you a feed id which you’ll use […]

  • Showing info on the Qnap NAS LCD

    With inspiration from lcd_tool and lcdmond on 419P I thought I’d make a little script that shows the hard drive temperatures on the display on a Qnap NAS (in this case a 419p): So, lets go to the home directory and create a file called ‘showonlcd.sh’: cd /home nano showonlcd.sh Then enter the following into the […]

  • Moving website to a new VPS

    I used to run my web server at home, but I decided that for traffic reasons it would be better to just rent a VPS (Virtual Private Server). The first one I tried was IT-staden (then called “serverconnect.se”), the best thing that can be said about it is that it was cheap…. I then decided […]

  • Linux the easy way

    After having run Windows 7 on my netbook (Dell Mini10), because there weren’t good Linux support for the GMA500 graphics, I wanted to try it again. I found myself without any CDR or DVDR’s, so I had to do the install with a USB drive, luckily this is made easy with LinuxLive USB Creator. Just […]
