Finally here are some photos from my latest Quadrocopter build. I designed the frame and all parts for the frame are milled from Carbon fiber og PE-300 with my CNC router.
I made everything so I would have enough parts for two Quadrocopters.
The frame has poved to very good except the legs tend to brake very easily. For my next design I will make some minor changes and try to organize the wires better. Also I want to be able to mount better camera to my quad.
I will post video from my latest flights soon. I am still learning the basics of how to edit the videos.
Ok, I have not blogged about this project before but I have been working on it for almost two years now on and off, the router project took a lot of time so I have not been able to work on this as I wanted. Since my router project is now “finished” or at least is up and running I have spent the last month working on my newest Quadrocopter. Before I make post on my newest progress I want to show you my first designs and toughts.
First of all I started to order all the parts I needed. I ordered alot of parts to have enough of spares in case something would brake. I bought the controller board from Aeroquad wich is a open source project. Other parts I bought there were the propellers. Other parts I bought from Hobbyking, I did buy a lot of wires, connectors, heat shrink tubes, carbon fiber plates and tubes and other parts I tought would come handy in the build. My initial tought was to make the Quad as light as possible. Below is my first design.
My first flight was not succsessfull to say the least, it went up trough two rolls and crash landed with the frame broken, all props broken and one motor damaged. This was quite frustrating but I started to make another frame. The frame was made from balsa wood and carbon fiber tubes glued together and was extremely light. The next flights were more successfull and I managed to fly but my pilot skills
were really bad. I added 1kg of steel bars on the quad to make it slower and more controlable. This helped alot and surprised me how much weight it was able to carry.
Here are few pictures of it almost ready to fly.
After a few flights my frame had sufferd a lot of beating and I had to make a new one. At this point I wanted to make proper frame so I decided to finish my router build.
It took me a while to finish the router build but now I have “finished” the router and also made the first frame with it. More pictures and videos from the build and the first flights coming soon.

It´s been awhile since my last post here but I have been busy last months on setting up my router, installing new spindle and another motor controller. I did fry my old stepper motor controllers due to the fact that I don´t know to much about electricity. I did put a switch on the dc site of the power supply that caused my breakout board to fry with smoke and everything. I therefore purchased a Gecko G540 wich I must say I really like, very simple easy and reliable and it reduces all the wiring and therefore reduces the changes of messing something up
Now I am using a Ridgid spindle wich works very well. The speed range is 20.000 to 30.000 RPM but it would have been nice to have slover speeds also avilable. This works fine tough with all material that I have cut except plexi.
I have to shield the lower bearing from debris from the spindle, For now I am using duct tape as a permanent solution. I also did purchase more spindle bits from trend ranging from 1,5mm in diameter to 3,2mm bot spiral and straight cut.
It took me awhile to get the right travel on the x-axis due to the fact that the axis is belt driven and I had to find the right tension to get good results, now the accuracy is 0,1mm wich I am happy with for now. Later on I will redesign this axis and put on a lower gear ratio for more accurate resaults.
I have also added limit switches on all axes and they are also my home switches. Here you can see the limit switch installation on the Z-axis.
And below you can see my first piece that I made after improvements.
And finally a picture of me.
I am now making parts for my quadrocopter so stay tuned for more to come.

If you like RC controlled planes, copters, cars or boats and fireworks you should ceck this out.
This guy has also done alot of other funny and cool stuff, click here for more of his projects.

Yai Finally my parts arrived, this was a long wait but they look gergous I must say:) Everything did fit do gether so now all parts have arrived so I can finish my assamble and start routing soon, hopefully.
When I first tried to insert the nut on to the ballscrew it went horrible wrong. All the balls fell out and they where so small. Fortunetly I had a bucket under to capture all the balls, I was worried this might happen. the reason for this mistake was that the tube that did hold the balls in place was not thin enough to go all the way to the to the threads. The tube that did hold all the balls in place was something under 12mm in inside diameter and therefore I could not take it all the way where the threads start since the diameter of the shaft was 12mm. The installation was easy, I just used some grease to hold the balls in place and made new tube to hold the balls with large enough diameter to fit over the shaft all the way to the thread. The second ballscrew went lot better.

Just saw this amazing software from autodesk. This is a 3D scanning software that only uses point and shoot camera. It actually works and in my opinion is quite mind blowing. It is accurate enough for visual look, but if your doing very precise work you would need to consider other solutions. I imagine this especially good for architechts and other planners that would need quick and easy 3D models.

At the moment this software is free to use. Just sign up here and download the software frome here and install and you are ready to go with your camera. I did try this software wita Canon ixus camera and worked better than I expected. You just have to keep in mind to take alot of pictures from all angles so all areas are covered and also to choose not to uniform objects to photography. For better instructions have a look at his video.
