Spectrograph.exe is a short program which can analyze sound waves when you speak into a headset microphone. Frequency is shown vertically, time horizontally and loudness is shown as colors. You press on the Space Bar, and then you make the sound into a microphone. It only works with relatively low speech-range frequencies. The headset microphone has to be plugged in Before starting the program, and adjustment of the distance to your mouth and your loudness is important.

...By tapping on the C and V keys you can change the Mandelbrot Constant, and this changes the patterns gradually in either direction. There are many keyboard controls you can tap on. The Page Up/Down keys trigger preset patterns. Random sounds are a combination of sine waves with harmonics, following random numbers, a separate experiment which happened to run in the same program. The complete source code is also here as one single ASM file, ready for assembly with the 'flat assembler'.

AVR beacon project utilizes a new approach to RF signal generation using SQDDS method (making RF signals directly from the software, based on a pre-calculated periodic bit-sequence). It is mainly used by the hamradio operators to set up various radio beacons for different purposes, mostly for radio waves propagation discoveries. CW (continious waves, Morze code) is a main modulation mode. Other modes like PSK and FSK are planned to implement in the future releases. User can enter any ASCII text to send it to the air. Transmission rates and modes are configurable from the input text. AVR beacon can read an external digital instruments like (voltmeter, thermometer, axelerometer, anemometer, etc.) and send its data to the air. ...
