It is by Hobby and DIY - Do it Yourself, Education Starts even without books. Then you need to read to enhance your abilities to Design your own.

In order to compensate or enhance your education, you need to work at a small shop as an apprentice even as a student, not for the sake of project work alone. An Evening job at a factory or a home mini workshop-lab is very essential for obtaining the skills - Solderman 1702

"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:"



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."

Multi-Instrument Digital Assistant - PIC16F84A - "It contains four instruments in one unit: logic probe, single channel logic state analyzer, frequency counter and serial code receiver."

The Engineer's Assistant - Erik Grindheim

"This compact instrument is intended to be a digital laboratory tool for hardware and, in some cases, software debugging. It contains four instruments in one unit: logic probe, single channel logic state analyzer, frequency counter and serial code receiver"



Serial code receiver The serial code receiver receives 42 bytes and displays them in both HEX and ASCII. The baud rate is selectale in 8 steps from 1200 to 115200.

Logic state analyzer This is a one-channel logic state analyzer. It fetches 300 single bit samples in a selectable rate from 25ms to 1µS (40 Hz to 1 MHz in 16 steps).

Frequency counter The frequency counter displays the frequency with up to 8 digits on the LCD. The refresh rate is 500ms.

Logic probe The low and high logic levels are displayed by LEDs which are OFF if the probe tip is floating.
