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.
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
“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.

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
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.
Build a true Webserver with only 2 chips. We did it! The used CPU (MSC1210Y4 from Texas Instruments) has 16kB Flash (up to 32kB available) and 1.2 kB RAM. Enough for a Webserver (provided you are using uC/51’s included TCP/IP stack).
Add Internet-Connectivity to your Applications with only a very few lines of C-Code. Many demos are included in uC/51, like: Webserver, E-Mail, Time-Client, TCP, UDP. Make Control System with remote Internet access to your sensors or actuatoors.

Electronic Projects for 8051 Development
Virtual walk through my 8051 development suite is a virtual sightseeing tour through my 8051 lab. Dual Slope ADC for 8051 – A low cost circuit to measure voltages with a precission up to 14 bit.
Some of the Projects here are
- 8051 Development – Code, schematics and hints for development with 8051
- Digital Frequency Generator -Frequency generator with DDS technology
- µC ADC – RS232 controlled 16 bit data aquisition
- Low-cost ADC – PC to take a look at signals up to 1 KHz
- Datalogger- 8 channel, 2 counter, 64K RAM, LCD, RS232
- MiniDS- Mini Digital Storage Scope, one channel, low cost ADC.
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.
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.
Here are some Training Boards with Teaching Software for electrical engineering and electronics. They also cover Mechatronic systems, Automation and Embedded Electronics.
hps SystemTechnik – didactic concepts
These are useful for vocational training, academic education and Introduction for Beginners. The PC is required for this Training Material and Boards.
Typ 3851 PIC Controller Board
Universal training system for microcontroller technology, Usually with varying PIC Controllers (16F84A, 16F876A,…), Programming in Assembler, only 35 commands necessaryCommunication with an PC over RS 232 interface, optional over USB interface
These are based on Practical Learning or “Didactic concepts” which means – Experiential learning, that expands to things like Factory or Field Visits, Build with Kits and Boards, Hands on Workshop sessions, Environment of the Science or Technology recreated or simulated in Interactive 3D. Objects, samples and Material that the learner can apply his senses on and perceive. Real Life Project or Problem he can tackle by applying his skills.
The best is of course, Apprentice Learning which has been there for centuries. In the ancient days if the father was a Blacksmith, the son would inherit his skills and job. This was because of unconscious Didactic Training the father gave to the son.
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.

“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….”
24 Bit / 192 kHz Audio ADC and DAC AD24QS and DA24QS
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.
