Filament review: ColorFabb PLA-PHA variables

This is the filament I have the most experience with, on both good and bad. I purchased my first rolls 1.5 years ago. I had worked really hard for a long time and thought that I would reward myself with some prime quality filament so I stocked up on 10 rolls of all the colors I wanted!

Teaching with robots

Teaching with robots

The last two years I've been teaching a course at Westerdals Oslo School of Art, Communication and Technology (formerly NITH). The school offers Bachelor & Master studies in informatics and I've been brought in as a teacher on the topic of Embedded Systems. The course (200 hrs total) is a volunteer topic for third year students that covers all the basic use of Microcontrollers as well as some Embedded Linux.

It's been a great experience and I get to play santa - giving students a customised version of this kit. 4Tronix have been very helpful in making me a super Arduino-kit that covers the entire curriculum at a price that the school can live with. The only part of the curriculum that isn't covered by this kit is robotics and motor control. This year I think I've found a near perfect solution that I though I'd share with other educators.

Filament review: NinjaFlex rocks!

Filament review: NinjaFlex rocks!

I've been meaning to test the flexible NinjaFlex materials, but having an Ultimaker made that impossible. Flexible filaments and bowden tubes don't play well as the friction of the plastic makes it curl and stop. With the new BAM printer, I have a direct extruder mounted just above the hotend. This is the ideal setup for flexible filaments and with the newly fitted Bulldog XL extruder it's a snap to change materials.

Filament Review: PET+ from MadeSolid

Filament Review: PET+ from MadeSolid

Some time ago I posted some tests done with Colorfabb's XT plastic. I'm guessing that the people from MadeSolid read that and wanted me to test their PET+ filament? I love testing new plastics so of course I said yes to getting some samples!

Making a custom 3D printer controller

Making a custom 3D printer controller

While working on my new printer, I realised how ugly most reprap controllers are. All those I've seen use large SD cards & bulky oldskool LCD's with really poor contrast and viewing angles. Why not use Micro SD & an OLED screen?

You can actually build your own custom controller using any combination of screen, SD reader and encoder, but I couldn't find a good description of how to do it, so here it is. Setting it up with the Marlin firmware can however be a daunting task, so this article aims to document how I went about doing it.

Why I’ll never use Windows Phone again

Why I’ll never use Windows Phone again

It's been a while since I posted a good rant. Here's one that's been brewing for some time. I refuse to belive that ANY Microsoft employes that ever had an iPhone or Android, actually tried to use Windows Phone for a full year. I have and I can tell you - it's utter bullshit. I don't doubt that a lot of talented people have worked hard to make it happen, but without someone capable of telling what is good and bad, you cannot succeed. The whole OS reeks of a lack of interest and use.

I gave it a full year as I figured they'd get som time to fix the major bugs. Despite three fixes delivered over the air, they have not solved anything that could help me like the platform. They have however added a menu with "Extra settings" that I'll never use.

Here's my 6 biggest annoyances:

Project: Makeblock 3D printer

Project: Makeblock 3D printer

Up until now I've had two 3D printers. My first one was the Ultimaker Original and it now has more than 4000 hours of printing behind it. An incredibly solid machine! The next printer was the Printerbot Jr that my son put together. I haven't seen much of it as he's more or less confiscated it, but it's been a great investment into making him try out some real engineering.

Project: wifi-enabled RGB LED displays

Project: wifi-enabled RGB LED displays

Every now and then there's a project you can't say no to and this was one of them. Finn.no is sort of Norway's version of Craigslist, a big online market where you can sell just about anything. As a marketing stunt, they opened a physical store downtown Oslo. I was called in via some friends in the agency that handled the project and they needed lots of things quickly. Since I was fully booked, I couldn't say yes to all the projects suggested so I passed some of them to my friend Thomas Winther who did a great job making an in-store Selfie-app using Unity & LeapMotion.

Summertime

Summertime

I really love those squeezed-in weeks of work in between family holidays. It's a rare time to catch up on thing like blogging, reading & updating a few personal projects. I just finished reading The Martian by Andy Weir that I got recommended from @hpeikemo. It's a really thrilling book that I'm sure we'll see as a hollywood movie soon. The story is kind of a "Robinson Crusoe meets McGyver on Mars". After reading it, I gave it to my son who completed it in just two and a half day. Great summer read!
