Repairing a Canton subwoofer 1st of March 2024
It always feels got to give a dead appliance new life and avoid binning it because of a small issue. In this case I made some step by step instructions if you have similar issues with a Canton subwoofer.

Just posted an article about my most old school project so far; an analog phone exchange. This enables me to build a small private phone network so our daughter can dial her grand parents (in the house next door).

Here's my slightly different approach to home automation: Everything centralized in one DIN mounted unit when you want things simple.

Mount everything in Eurorack 13th of April 2021
The Eurorack modular synth standard divides a 19" rack into smaller units. Inspired by this I have mechanically redesigned everything I had floating around on my desk so it could be rack mounted and let my CNC router eat through aluminium sheets all day and night. This post is meant to give you some ideas on how you can mount everything in Eurorack.

eSMART3 MPPT PV charger review 18th of April 2018
I buy a lot of electronics online, but rarely write anything about it. Recently I've been buying some components for an offgrid solar installation, and this charger is one of them. Unfortunately I couldn't find much information about it before buying it, so after testing it I decided to write a little review for others who might find it interesting!

Trip computer and tracking for Citroën C-zero 18th of November 2017
The C-zero is a cheap and popular electric car in Norway, along with it's "triplets" Mitsubishi i-MiEV and the Peugeot iOn. However, to keep the cost down, it lacks features such as a trip computer and remote tracking and monitoring (at least my 2012 model). With the shutdown of the FM broadcast band in norway, I had to do something with the radio, and used the opportunity to make something more out of it.

skagmo/hapcan-contribution 12th of February 2017
Check out some of the the work I have done on my home automation system. It is based on a CAN bus running all the way through the house connecting switches, relays, dimmers etc. For this project I needed to connect the CAN bus to some DALI LED drivers, and made a module specifically for this task. https://github.com/skagmo/hapcan-contribution

Gløsrover 1st of November 2015
I just published an update on my little rover project. Mark 3 is WLAN-connected and a Raspberry Pi is now a central part of the design. It was actually finished over a year ago, but I never got around to update the page. https://www.youtube.com/watch?v=48PBKZT3reA

Bilder på tidslinjen 25th of February 2015
Finally! The first machine produced batch of the Owl has arrived. Although this is a long step forward, it will still be a while before the radio is available for radio amateurs. Check out the full update on http://www.skagmoelectronics.com/

Maximum power point charger for solar panels 13th of June 2014
Skagmo.com is now on GitHub, and I will try to share as much as possible of my upcoming non-commercial projects with you. This typically includes code, PCB-layout etc. I've also got a new project I want to share with you - an MPPT (Maximum Power Point Tracking) charger for use with solar panels. http://www.skagmo.com/page.php?p=projects/28_mppt-charger
