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

May 29th, 2009

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

Mikrokopter with DUBwise V0.52

April 8th, 2009

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

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

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

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

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”

Onboardvideo with EPI-OSD

June 23rd, 2008

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…

GPS + Mikrokopter (III)

June 3rd, 2008

Hi there!

Here is a small video about the calibration of the MK3Mag and the position-hold feature of the NaviCtrl together with MKGPS1.

Mounting of MK3Mag on the NaviCtrl

June 2nd, 2008

Hi Guys,

Today I want to describe the mounting of the MK3Mag on the NaviCtrl board.

To have a good connection you have to solder the multi-pin-connector inverted and fix the MK3Mag with two screws to the NaviCtrl. If you look at the following pictures it should be self-describing.

Without the mechanical connection to the NaviCtrl the MK3Mag may fell of during flight – and it will be VERY difficult to find it again.

GPS + Mikrokopter (II)

June 1st, 2008

Hi there!

Today i finished the construction of my “third” MikroKopter. In the moment the Mikrokopter is a “patchwork” of the other two that i buildt before.

I have made a lot of pictures to illustrate the construction of my very simple MikroKopter. I believe that it is possible to build it up in one day.

Another very cool thing is the new NaviCtrl, which is currently in testing-phase by the MK-Betatesters and will be available for the community in some weeks. It’s a board with an ARM9 32 Bit Mikrocontroller on it (STR911FA). There are also a lot of connections free to have a lot of fun. For example: GPS, MK3Mag, USB, I²C, SPI, UART, … That means that the MikroKopter community has a new “playground” for the next months.

Of course the new NaviCtrl works best together with the MKGPS1 (a GPS board with an ublox LEA-4H chip) and MK3Mag (a three-dimensional magnetic sensor – which is used as a compass). With the actual releases for the Betatesters of the Mikrokopter community i can say that the MikroKopter stays in the air in a way that you would NEVER expect.

I have also filmed the autonomous position hold. I will try to put the video online in the next days.

Ok, enough written – here are some pictures:

So the MikroKopter gets more stable and now it’s time to test the FPV CCD camera from Sony together with the EPI-OSD (on screen display) and my video goggles.
