Fritzing is Product Design or EDA in Simplicity

"Fritzing is an EDA - Electronic Design Automation software with a low entry barrier, suited for the needs of designers and artists. It uses the metaphor of the breadboard.."

Fritzing is Product Design or EDA in Simplicity

"in the spirit of Processing and Arduino, developing a tool that allows users to document their Arduino and other electronic-based prototypes, and to create a PCB layout for manufacturing."

Fritzing Starter Kit to start learning Arduino

What do you get? The ultimate beginners book teaches you everything you need to know through a series of practical--yet playful--exercises. And that playfulness is the key! There is a paper robot who can turn his head; a fortune teller who is (of course) never wrong (no guarantee on that); a dinosaur who relays the news on your Twitter stream and a pong game on a big LED matrix display.

Fritzing Starter Kit to start learning Arduino

Fritzing's goal is to provide easy tools for documenting and sharing physical computing projects, producing layouts for Printed Circuit Boards (PCB) and teaching electronics.

    Museum Of Electricity - Charles Brush

    Yes, there were electric lights powered by central stations before Edison's! Carbon arc lamps saw extensive use throughout the USA and the world from the late 1870s on. - Charles Brush

    Museum Of Electricity - Charles Brush

    The General Electric Company was formed in 1892. It was the result of a meger between the Edison General electric Company and the Thomson-Houston Company, which themselves incorporated several other companies.

    Electricity, technology, and lots of arcs and sparks!

    Museum Of Electricity contains Vintage Electrical and Historical images and description. They include the Edison Lamp, Tesla Coils, Lightning and Atmospheric Electricity and the .....

    Amazing Jacob's Ladder

    So how do they work?  First two conductive metal rods are positioned in a rough “V” shape with a slight space between them at the base.  A sufficient voltage differential is provided from a high voltage transformer to breakdown the air in the gap between the rods.

    Single Digit Voltmeter with LM311

    I wanted to design a logic probe as a tutorial, but there were many good ones in the web so i have tried to design a single digit voltmeter. This circuit is a design, i am unable to test it now, later if i test it and find mistakes i will update this page. You can help me by pointing out the errors.

    Single Digit Voltmeter with LM311

    First bear it in mind that it is a single digit voltmeter which is 0-9 counts only on the positive side, that is it can measure +0 to +9V DC +/- 1V error. That may not be practical for the cost of the components above. It may be used as a toy logic probe. The reason for the circuit is not for usage, but to give design ideas. The methodology used is Gut Feel - Thumb Rule method.

    • Projects - Complete listing of ESP's free project and design articles
    • Articles - Informative articles about audio, building projects, and electronics in general
    • Buy PCBs for ESP Projects - boards supplied have very comprehensive documentation.
    ESP Resource of Rod Elliott - The above pages has many useful ideas and practical tips - delabs

    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 - 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:"



    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."
