"It is quite easy to use also meters in formulas.Here is some simple mathematics:- Distance from equator to North pole is 10 000 km- Distance is also 90 degrees- So 1 degree is 10000 / 90 = about 111 km.- 1 meter = 90 / 10 000 000 = 0.000009 degrees-…"

Here is my memo: How to save gps-coordinates to picture files with Geosetter program. The coordinates are saved to the picture exif-data, and these go with picture all the time. In exif there are already data from camera model, exposure time, lens focal length etc, now we add there gps coordinates.

For example here is picture info in Irfanview program. Coordinates and…

Here is my memo: How I make camera launcher from old servo electronics, usb-cable and diode.

Here are quite many steps, so I write this memo if I need to make system again... Programming took only few minutes, to build circuit took more time.

My camera is Canon PowerShot S90

 

  1. Buy max 4 Gb memory card to camera.
  2. Create…

This is a special version for aerial photography. On the plane there is a stabilized camera.

Here is the camera stand. Guess what is the weight of it? ;-)

I have also made additional code to APM, so I don't need a computer to make…

I made a program that shows log data in visual way. I can see plane position, altitude, elevator, ailerons etc.

Here are some screenshots from program:

My plane made strange curves during flight. All curves are in the same places. After a very careful check I found an error in APM navigation code. It is now corrected in version 2.21 (In downloads section…

Hello Alpo,

I sent you a friend request a long time ago.... :(

I read about your plane TaigaCam and found it great with robustness and good possibility for FPV.

I would like to build a similar one for myself

Would you agree to help me?

Best regards,Jean-Claude

Forgot to add that my first objective is to perform aerial photography

Then perhaps later FPV flying

Regards,

JC
