Amateurfunkbasteln - Amateur Radio Crafts and Electronics

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.

DIY Electronics Section of Beis.de

Here you will find Audio Oriented projects, many in the German Language. There is one - Converting Analog into Digital (IIR) Filters which is useful for Mixed Design students. Then there is a FPGA-Based Digital Audio Peak Level and Correlation Meter with many features. The Hi-Fi Audiophile will like the Tools - Audio Preamplifier, Weighting Filter Set and Universal Filter.

24 Bit / 192 kHz Audio ADC and DAC AD24QS and DA24QS

"It is very well known what kind of deviations from the original signal a human ear is able to hear (e.g. distortion, frequency
response, noise etc.) and also in which amount and under which circumstances this is the case. All these deviations from the original
signal are measurable with a precision and sensitivity far, far superior to the human ear...."

An Introduction to Delta Sigma Converters

Delta sigma converters are different from other converters. Note that I do not make a difference between analogue-to-digital (ADC) and digital-to-analogue converters (DAC). Both are very similar and what is realized in one of them using analogue signal processing circuitry is implemented in the other one using digital signal processing and vice versa. I will explain the delta sigma technique with the analogue-to-analogue delta sigma converter as the first object.

Strippenstrolch - Elektronikbasteln

"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.

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:"

Solar Pump

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."
