The Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution. The data source can be selected in the Windows mixer (Microphone, Line-In or Wave). The frequency range depends on the sound card, but 20-20000Hz should be possible with all modern cards.
Soundcard Oscilloscope by Christian Zeitnitz
The oscilloscope contains in addition a signal generator for 2 channels for Sine, Square, Triangular and Sawtooth wave forms in the
frequency range from 0 to 20kHz. These signals are available at the speaker output of the sound card. These can be fed back to the
oscillocope in order to generate Lissajous figures in the x-y mode.
These is another good tool for students to learn measurement on the PC. – delabs
“Strippenstrolch” is thus a pitch name for “electricians”. here you can also see a innovative project that combines rainwater harvesting and a solar energy operated pump to flush toilets.
Strippenstrolch – Elektronikbasteln
LED Lighting Projects, Learn Electronics, Basic Circuits and how they work. All in German.
“In Germany one finds this designation now and then for an electrician on the work. Particularly in the winter, if it is still dark in the morning, one often sees “Strippenstrolche” with its building lamp on the building site:”
Combination of Rain and Sun Harvesting
“The inspiration for a self-sufficient toilet flush was now close at hand: I thought at first to work with a power supply that provides me the 12V to the pump. But as a power supply would idle constantly consume energy, I rejected this solution. I have long experimented with solar power, so I decided, now a solar system for our toilets to build. On the flat roof of our garage I installed two 12V – 55Wp – solar – modules (Conrad Electronics). This I switched in parallel.”
“As a solar storage currently serves an ordinary car battery 45Ah (later 3 pieces with a total of 135 Ah). The charging control acquires an 8A charge controller (Conrad). So all very simple.”
Author of books and CDs, Microcontroller, interface programming or new ideas for hobby projects. The Electronics Fundamentals for hobby and education helps the beginner with valuable information.
The electronic logbook is amazing, you can have a look at so many circuits and projects with photos. You will learn many things and make you develop skills.

Electronics experiments for children – “For children it is easier than for adults. Since it is enough, if someone applied sufficient time and a little tinkering with them. Often all it takes is a little push to arouse interest and skills.”
