Castle Thale gets an upgrade

Posted on Updated on

2015-11-09 10.54.58

Led lights finally found its way on to Castle Thale!
Our little girl is now 1,5 years and the castle is now on the wall in her room!

At night, only the 4 lights in the guard towers are on, while the rest of the tower is asleep🙂 Makes for some nice nightlight for Thale.

Soldering iron + Nodemcu = IoT device

Posted on Updated on

My tProwl warning soldering ironrusty old soldering-iron recently got an upgrade!

With the help of a NodeMCU. a RGB-LED it now reports the set temperature to the #IoT server through WIFI.
It also sends me Prowl messages on my Iphone when I forget to turn it off.

It all started when I needed to fix the display on the Soldering-iron itself after some guys at the soldering-iron factory forgot to mount the segment display properly.
The road to IoT is anything but streamlined yet. The NodeMCU & Arduino IDE integration is in it early stages and the tutorials out there are few and full of frustation.

Join me and read how I went on with the Soldering-iron #IoT project here!

Building a castle for our little princess

Posted on Updated on

Quote “Every princess needs a castle” -Vegard Paulsen 2013.

In december 2013, when we found out we where expecting a little girl, my wife and I decided that we would need a princess castle! After all, we were expecting a little princess, and according to a comment i made earlier that year it was time to build one.

But how to build a castle inside a 66m2 small appartment? Our prototyping skills really came to good use this time.

Unfortunately we live in Norway, and have never been to Disney world in USA. To never actually have seen the Disney Princess Castles made it difficult to draw one out of my own imagination. I honestly had no clue how it would look like other than Disney movie references from Sleeping beauty, so i started searching away on the internet after Disney sleeping beauty castle. I soon in love with the design of the original “Sleeping beauty castle” in Disneyland Anaheim in California!

The next step was to start figuring out how to make that castle a part of our little daughters bedrom!

This was a huge project to take on right before a baby arrives.

Assembling my new delta-3d printer

Posted on Updated on

I have had my trusty Makerbot Thing-o-matic 3d printer for over 3 years, and its time to move on to a bigger, better one, as the cost of buing spareparts on the old one gets higher every day. The trouble of repairing the Makerbot all the time vs the cost of upgrading to a newer one with larger build area and faster buildtimes made it an easy decicion!

I recently purchased the Seemecnc Rostock Max V2 kit from and started putting it together right away when it arrived. With a build area of 28cm diameter, and a build height of almost 40 cm this should be fun! 

25+ build hours later, its now time to share some pictures of the build.

Prototyping: Quadcopter version 1

Posted on Updated on

So i built myself a quadcopter in january 2014. Instead of buying a Ready-To-Fly multicopter, I plunged into building my own and it isn’t difficult as long as you choose a nice flight controller and have a bit of experience remote controlled things and know how to use a soldering iron. 1528693_10152115678478050_117608398_nI went with the popular DJI Naza controller with a GPS module and gathered the rest of the parts from scrap in my workshop and on cheap hong-kong-based websites. I Planned and sketched the design in Google Sketchup during christmas 2013 while i waited for the motors and the ESCs to arrive in the mail. I milled the parts i needed on my Probotix Fireball CNC and 3d printed some parts on my Makerbot Thing-o-matic. quadcopteret til vegard v11DTotal hours of build was probably about 20-30 hours in my workshop, and most of them drawing in sketchup and milling parts, waiting for the 3d-prints or soldering up cables. I also built two voltage regulator circuits with a 7805 (5volt) and a 7812(12 volt) for powering the electronics that didn’t like 14.8Volt from the 4Cell lipo battery, mounted the voltage-regulators directly to the aluminum frame for cooling, and soldered everything together at my workshop.
The quadcopter has an unbalanced frame with the two front arms pointing away from the camera in front to make sure the camera doesn’t film the propellers or arms. At first i was a bit afraid of the unbalanced frame being a problem in the air, but the DJI Naza controller fixes everything and really gives a smooth controllable flight in GPS mode.

The multicopter was a success and had about 25 hours of flight-time until its life ended with a fatal bird-strike in one propeller at 100 meters altitude over a large empty field.

So the copter worked beautiful until it had a bird-strike in mid-air crashlanded in a tiny river far, far away. Recovery-mission was launched but just as the Malaysian flight 370 that disappeared the day before the crash, the multicopter went into stealth mode and was never seen again. The river is definitely muddy and location of impact is unclear. I considered to go home and get my drysuit and divegear but the visibility is really down to zero in that muddy water and its probably full of chemicals as well so a new episode of “aircraft investigations” will have to wait. 1527054_10152237288838050_314914996_n The expensive parts is not recoverable after being soaked in water so i wrote the copter off as a nice working (and expensive) first prototype.

Here is the build log of my copter as well as some hard learned lessons and a lot of pictures of the build.

3d printed instruments

Link Posted on Updated on

3d printed instruments3d printed guitar

Making a prototype of a new invention was an expensive and time-consuming process in the old days. Huge machinery combined with long waiting times and large startup-costs made inventing hard.

Todays technology has made it easier to make a fully working prototype of your idea in a short time, with a tiny budget.

Using smaller lasercutters, CNC machines and 3D printers make the process alot easier with ultra-high precision. The low entry price point of the new smaller machines, rapid prototyping and cheap material, easier to use interfaces & control of the machines makes it accessible to Do It Yourself (DIY) creators / makers and inventors out there.

There is no longer a closed society for inventors and engineers, and the fear of somebody stealing your idea has changed. People speak more freely than ever about what they know and share ideas online. You can´t sit to long on an idea anymore, somebody else will think of the same thing and possibly create and sell it before you do, so its more important than ever to make and sell things fast.

With searchable tutorials on the internet, and opensource forums and DIY groups and chat forums to share development ideas and techniques, makes it easier to understand and learn how to adopt to new technologies and create your product without having a degree in engineering.

The use of these highly advanced prototyping tools are becoming widespread all over the world. Its only natural that we start using this technology to develope more advanced stuff, and music instruments is no exception. Check out this webpage / wiki that acts as a opensource encyclopedia for all DIY instruments. Download a cad file and print your own on your 3d printer or cut it on a CNC or a laser cutter.

The future is here, and i can´t wait to try out all the crazy new instruments being created by tomorrows DIY inventors!
