Society against photo manipulation

Why manipulate picture's? Is it just to make a virtual world. Personal I hate when people manipulate pictures because a photo should show the real world not the world depending on what photo software you are using.

Antenna test

The antenna test went well I could hear ssid becon's 7 kilometers from test field

Wifi antenna

I have made the first test antenna today. I Will put it All together tomorrow.

WIFI antenna on PCB.
I found a Yagi antenna design at the internet. I made a drawing in EAGLE next step is to sear the antenna on a PCB and the the final test - is it working?

Playing with the ALPHA net card is a joy. I'm using Linux / Ubuntu and the aircrack-ng package. To install the package in Ubuntu. Open a terminal window. Type sudo apt-get install aircrack-ng. To place the net card in monitor mode type airmon-ng start wlan1 (wlan1 = the net card). If you run a ifconfig you should find a mon0 device and everything is ok. To run wireshark type sudo wireshark and it starts. Good luck.

Renovating old power supply

Today I began renovating my old power supply

NDB Filter 533 KHz LPF

First try making a NDB 533 KHz low pass filter

FAU Ronne

Picture of FAU locatet near Rønne airport. It is transmitting at 334 khz. It made me think back on old loop antennas that I made for NDB intercept.

Lm2917 part II

I have made the first converter board for the magnetometer. Next step is to test it

LM2917

I got all the things for the first try making the magnetometer frequency to voltage converter.
