Including Native extensions on OSX

Making a small GUI project that controls some hardware today and stubled upon a bug that I solved when using the neat COM-port extension for AIR by Nick Kwiatkowski.

Filament review: Printing with potatoes?

One thing that fascinate people about 3D printing is the fact that the PLA plastic we often use as material is made from Corn. Now you can get a bioplastic made from potatoes as well! In this review of the bioplastic called Biome3D I'll highlight how it prints and how it differs from other materials. It has some quite useful properties!

Beta testing for Makeblock

Beta testing for Makeblock

Some weeks ago, I was asked by Makeblock if I wanted to review a kit that they are putting on Kickstarter? I guess they asked my since I've written about some of my other Makeblock experiences and use it for most of my robotic projects, and of course I wouldn't mind testing out something new. But - I got an idea - who better to test it than my 10 year old daughter Vera? They liked the idea and sent the kit off.

ESP8266 and stability

ESP8266 and stability

Please note: this article is 3 years old. Since then a lot has happened to the ESP's. They're more stable since version 1.1x and they are now super easy to integrate with the Arduino IDE.

Like many others in the Maker Community I've spent a lot of time playing with the dirt cheap ESP8266 wifi chip. It is the cheapest way to add wifi to your project and it's easy to get hold of. My hope was that it would be solid enough that I could build permanent installations and fun Internet Of Things (IoT) devices with it, but the darn thing keeps crashing. I've been testing it since the 0.91 firmware and all the way up to the current 1.0 version and it's not possible to keep the device running for a prolonged period of time.

Spark Core shows solid magenta LED

Spark Core shows solid magenta LED

I've been head deep into a great game-project where I'm using UNO & Fuse for the first time on a commercial project. Before this, I spent about two weeks making a nice LED sign that will be used at Bitraf above our mini-hackerspace-shop called Bitmart. I want to be able to control this using any phone so I spent a solid amount of time getting various ESP8266 boards play nice with a Teensy 3.1. That turned out to be a nightmare. I originally intended to make a library around it, but I gave up. They are simply too buggy and running the auto-update makes it corrupt itself, so I now have 4 dead once's that I'll have to flash.

Unpacking the Titan 1

Unpacking the Titan 1

I just received my fourth 3D printer and the first to use SLA technology. I've followed maybe ten 3D printer projects on Kickstarter, but Titan1 is the first one where I have actually ordered a device. On the other one's I've just been part to follow the project and see if they're posting "the right things" and this was the first vendor to gain my trust. As opposed to most other KS printers, the people from Kudo3D kept posting different reviews of materials and showcased prints.

Filament review: PlastInk Rubber

Filament review: PlastInk Rubber

This flexible plastic filament from the Italian company PlastInk has been on my desk for a while and it's quite interesting! It's flexible, has massive friction and behaves like Nylon in many ways.

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.
