Information for the Electronics Hobbyist

This site contains information about electronics, computing and science in general. I mainly try to gather information about subjects that interest me, and I hope that it might be valuable for others. At the moment you will mostly find information about digital signal processing and GNU Radio. There is also a little collection of source code in order to do useful things concerning digital signal processing. In addition to this, you will find general information about different other subjects related to electronics, physics and computer science.

The picture at left presents a simple FM Radio transmitter constructed in an interesting way. It is all that is needed in order to block out the radio of your neighbor. On the right, there is a simple radio receiver (superregenerative), which has the capability of receiving normal FM broadcasting channels as well as the AM-modulated VHF communication between pilots and the tower at airports.
