EPI-OSD (with C-OSD Software) + Camera

May 29th, 2009 by Speedy 5 comments »

Hi Guys!

Yeah, it’s summer and now I have time to continue my investigations in FPV-flying. Some weeks ago I had a little disaster and crashed my FlightCtrl and my NaviCtrl (shortcut in the connection cable).
So I had to order a new NaviCtrl immediatly. I had luck, the MK-GPS and EPI-OSD survived.

And now – my Kopter is back 😉 (better than ever *ggg*)

Ok, let’s get to the topic.

A lot of people asked me, how I mount the camera and the EPI-OSD on my Mikrokopter. Thats a little bit complicated to explain and so I took some pictures to show you how I did it.
Update – 30.05.09: Attention, if you want your C-OSD Version to work fully together with the NaviCtrl you have to connect the EPI-OSD to the debug port of you NaviCtrl!


I hope that I will have some time in the next weeks to do my first FPV Tests with video recording to post it here (maybe the weather is nice 😉

Preview of functions of the “system-technic-robot”

May 9th, 2009 by Speedy No comments »

As you probably know I am a member of a team that has to built a robot. This is part of my education at the NTB in Buchs in the first two semester.

Here is a short clip of the actual status. Details will follow at the end of the project.

Some facts:

  • Robot controlled by WiiMote
  • A PC/Laptop has a relay application that realizes the Bluetooth communication (Software: LabView)
  • WiiMote -> Bluetooth -> Labtop -> Bluetooth -> uC -> Motors/Sensors (Bidirectional of course)
  • IR-Sensors (Sharp Type GPD120)
  • Stepper Motors
  • LiPo power supply (11.1V / 3p1s)

Open tasks (“todo”)

  • give it intelligence (autonom)
  • communication with partner team
  • final documentation
  • preperation for public presentation

WiiMote connected to LabView and uC

April 8th, 2009 by Speedy No comments »

This year I have to do another nice project. It’s a robot that has to fulfill a job together with another robot from a partner team. More details in some weeks (photos and videos).

The project is part of my education at the NTB in Buchs. We are a team of 8 people and I am a member of the programming team (and some support in electronics). During the last weeks, the mechanic team did a great job and the prorgamming team had enough time to do funny experiments with our mikrocontroller.

One of the funny things was that we connected the Wii Mote to the PC and then the PC to the mikrocontroller. All this was done by bluetooth – so no cables – and that’s really nice.

Here is a nice video clip of the LabView Software in action:

In some weeks I’ll post a “full action movie”. But first the mechnical and electronic parts have to be assembled fully.

Thanks to my team at the NTB! It’s great to work together with such a highly motivated team.

Mikrokopter with DUBwise V0.52

April 8th, 2009 by Speedy 1 comment »

Hi out there.

In the last days i tested the new version of DUBwise (Digital UFO Broadcasting with intelligent service equipment – coded by LiGi). The Kopter is connected via Bluetooth to the mobile device. In my case this was a Sony Ericsson W810i.

The actual Version has the possibility to adjust all Settings (like the MK-Tool) and nice features are the Graph indicator and the Cockpit which displays a virtual horizont.

It’s a amazing tool and supports a lot of mobile devices. Ligi is also updating and patching all night long to be in sync with the latest released Software from the Mikrokopter project itself (FlightCtrl, NaviCtrl)

The tool is also able to talk and tell you how full the Lipo is (Voltage). Other nice informations are the number of satellites, height over ground, heading, distance to home position and so on…

To see how the tool looks in action here is a short clip:

Details about the project you can find at  http://www.mikrokopter.de/ucwiki/en/DUBwise or http://www.ligi.de

Update 14.04.2009: Because some guys asked me how to install the application on their mobile phone, here is an instruction. For the installation you can use the “Installer” from LiGi (http://ligi-tec.blogspot.com/2009/03/dubwise-installer.html).
If you have no internet connection, the installer shows you which file you have to install for your specific device. The sources and binaries you can find here: http://svn.mikrokopter.de/mikrowebsvn/listing.php?repname=Projects&path=%2FDUBwise%2Ftags%2Fv0.52%2Fmisc%2F#_DUBwise_tags_v0.52_misc_

Mikrokopter Upgrade (FLEX-lander, BT, LEDs)

April 2nd, 2009 by Speedy No comments »

Yeah – I finally had an evening “free” or “spare” time. So i used the time to mount my new FLEX-lander from the Mikrokopter shop. Also I am now a proud owner of a MK-USB. It’s so sweet to have the power supply of the Flight-Ctrl direct in your programming interface.

Additionally i “reactivated” my bluetooth device and added a BT-AP10 to the BT-Module. Now everything looks clean and smooth – and – I’m able to test LiGi’s very cool DubWise again! I’ll try to make some screenshots or a video next week (Yes, I can’t believe it, I’m “on holiday” next week)

The weather gets better and better, snow has gone and the “freezy fingers” from flying in winter are also history. The new Mikrokopter season has started 😉 (For the most Mikrokopter freaks in the form it never ended)

Additionally my NaviCtrl got a Micro-SD card with 2Gig capacity for recording flight tracks and telemetry.

Here are some photos of my current Mikrokopter status:


Testing Sharp Distance Sensors

February 10th, 2009 by Speedy No comments »

Hi Guys!

Finally I finished the first semester of the NTB in Buchs.
Beside working for my company I had to learn a lot – but – I also had some time to combine the requirements for the “robot” project in the first year with a possible nice feature for the Mikrokopter.

I’m talking about the “traditional” IR (infrared) distance sensors from Sharp. There are different types of them, for example: GP2D12, GP2D120, GP2Y0A02YK (GP2Y0A02)
These three types are sensors that have an analog output (there are also other sensor-types from sharp with adjustable or fixed digital outputs)

The sensors have a very simple interface:

  • Power Supply
  • GND
  • Analog Out

That’s it!

The difference of these three types that I tested is the measuring distance or let me say their “sensitivity”.

For example the GP2D12 specification is:

Range: 8cm to 80 cm
Supply: 5,0V;
Vout: 0,4V bis 2,6V typ. (80cm – 10cm);
Current: 33mA typ.

Typical feedback:

As you can see the output voltage is not linear to the distance – but that is not a big problem for the softare, if you know that behaviour 😉

The GP2D120 if from 4cm to 30cm and the GP2Y0A02YK is from 20cm to 150cm.

Mikrokopter has a new logo

October 3rd, 2008 by Speedy No comments »

Hi Guys.

Finally the mikrokopter has now his (it’s ?) official logo. Small modification of the logo are possible, but in general the logo will look like this:

My new Fatshark goggles have also arrived. My sparetime to test the goggles is very rare, because I started to study system engineering at the NTB in Buchs (beside working for my company).

I’ll try to update my blog with activities beloging to the mikrokopter and the new project at the NTB.


My new home, Mikrokopter logo competition, Mikrokopter meeting and other stuff

September 3rd, 2008 by Speedy No comments »

Hi Guys!

For a long time nothing special happened in my blog. The reason for this was the moving from home to my new flat. In the moment I only have UMTS / HSDPA to surf and check my emails, so no pictures or videos can be published by me.

This will change in two weeks, when I will get a broadband Internet access (hopefully).

Last weekend I was at the Mikrokopter meeting in Zürich / Switzerland with some guys out of the Mikrokopter Forum. There i crashed my Mikrokopter (He is already “reanimated” with a new ALU-standard-frame). Photos of the crashed frame, the meeting and video of the meeting will follow in two weeks.

Also I participated a group buy in the forum. There I bought a FatShark Video goggle. Maybe the goggle will arrive also in the next 2-3 weeks.

And finally Holger and Ingo (and the Wiki-Team) is searching for an Mikrokopter logo. If you have ideas for a logo you can send it to logo(at)mikrokopter.de. After a preselection of Holger, Ingo and the Wiki team, the Mikrokopter community will vote for the best one. The winner will get a 200€ credit for the Mikrokopter shop. Details you can find inside the forum.

Oh yes, at the 15th of september I’ll start to study extra-occupational at the NTB in Buchs (Switzerland). So my sparetime will decrease from “almost nothing” to “I don’t need to sleep” 😉

Paragliding – A new hobby?

July 7th, 2008 by Speedy 3 comments »

Hi Guys!

Last weekend I had the chance to play with a para-sail of a friend of mine (Manuel Wehinger). He showed my some interesting basic things of paragliding and we played a little bit in the field.

There wasn’t enough wind to have “real” fun – but it was enough to get a feeling of “how strong a little bit of wind” can be.

In the moment I don’t have time to start a new hobby, but I think that it will be interesting for me in the next few years. I am fascinated of “flying through the air” since I’m young. I have often dreamed of flying with a para-sail in my childhood and maybe this dream will come true in some months or years.

A big “thank you” to Manuel for showing me some interesting stuff in this topic (He is already a pilot and has the licence)

Photos of the session are added below:

Onboardvideo with EPI-OSD

June 23rd, 2008 by Speedy 3 comments »

Nice weather at the weekend – so that’s the result.

A nice flight in my village (250 inhabitants). You can see our house, our garden, the small church beside our house. You can watch the video in fullscreen – it still looks very nice. – Enjoy

Pictures with details of the setup will follow…
