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:”

Strippenstrolch - Elektronikbasteln

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.

Elektronik und Mikrocontroller – Burkhard Kainka

For the advanced Hobbyist there are projects on Microcontroller and Measuring and control devices with the USB and PC Interfacing,

SDR Radio with USB

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.”

Two new circuits with AVR: Universal timer and frequency clock, in addition new software for the ATTiny11-Programmer, in order to be able to program also Tiny12 and Tiny15.

ELektronik Kompendium

Two new circuits with AVR: the fluorescence indicator control with HD44780-Emulation and the simple radio clock with various indicator options. In addition a Perl Script for the RS232-zu-LCD-Konverter for the use with XMMS.

Second update: Transmitter circuit for the RS232-Interface without Microcontroller with 8 entrances, in addition the texts somewhat revises and restructures.

16-bit to seven-segment

16-bit to seven-segment

“This circuit is used to represent a binary word (up to) 16-bit to seven-segment displays. Changes the binary word, the display is updated immediately. If fewer than 16 bits are displayed, the unused inputs can be connected to ground easily. A switch between six different display modes can be switched”

Amateur radio is a technical hobby. The attraction? To cover long distances with a low power radio to talk with other people, learn about their countries and cultures.

Amateurfunkbasteln – Amateur Radio Crafts and Electronics

But amateur radio also means tinker devices themselves, solder, apply electronics and learn something. In this sense, it can be a preparation for a technical career or even an engineering degree.

Use Google Translate, the pages are in German.

A Data Logger that records Slowly varying parameters, such as the temperature or decreasing the voltage of a battery. This copy records up to four measurements on parallel and saves it on a EEPROM.

Four Channel Data Logger - Amateurfunkbasteln

Four Channel Data Logger

It measures self-sufficient – without a PC – analog voltages (0-5V), it digitizes and stores the numerical value obtained in a separate memory. Later, after the measuring and recording phase, passes the data logger its information to the PC.

Amplifier.cd - measuring instruments - audio

The Content consists of theory, test, analog technique and measuring instruments for amplifiers, electronics and Hifi.

A Tutorial describes fundamental ideas of electro-technology and the general amplifier and audio technology. The test equipment gallery shows measuring instruments – older, historical and partly new.

7A42 is 4 channel Plug-in amplifier

Obsolete Test Equipment Gallery

The 7A42 is 4 channel Plug-in amplifier up to 350 MHz. Conceived for the measurement of logic signals and offers the possibility for triggering the inputs logical AND/OR. So 4 data lines can be observed at the same time on the oscilloscope.
