“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..”
“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.”
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’s goal is to provide easy tools for documenting and sharing physical computing projects, producing layouts for Printed Circuit Boards (PCB) and teaching electronics.
RoboBrrd is an animatronic character designed to be utilized as a tangible physical interface to interact with learning applications for elementary school students. A Smart Robot Bird. A Edutainment aid Bot Avian.
Impy RoboBrrd – Nicknamed ‘Impy’, short for ‘Important’. This is the latest RoboBrrd, and the official prototype that sparked the creation of an Instructable and intense documentation for the RoboBrrd robots! Impy uses a standard Arduino as a brain and has a NFC reader to see what hats it is wearing.
With RoboBrrd being a tangible physical interface, the students will interact with RoboBrrd to control the in-game character within the learning application, and RoboBrrd will motivate the students to keep playing with chirps and celebratory dances. Different behaviours in RoboBrrd will be unlocked for every level that is beat,
“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:”
“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.”
Here are some Metal Detector Projects that are quite interesting for the purpose of education and experiments in the Art of electronics. This site may be as old as Y2K, but the url / domain may have changed.
If you are interested in the theory behind the mag I can highly recommend the book The Magnetics Measurement Handbook by J.M. Janicke. Besides a good coverage of magnetics theory, it contains much of what you need to build a useful fluxgate Magnetometer, plus other devices.
Traditional Geophysical instruments include ground-penetrating radar, earth resistivity meter, infrared, and sonar, to name a few. Currently, earth resistivity projects are the most practical for the do-it-yourselfer, although some people have been tinkering with side scan sonar.
Detection of Gold
Just the Jeohunter really works and directly detects Gold – see below screen. And even gold-worth 9-15cm diameter cannon-balls get detected as “Gold” (golden ring & cannonball analyses has identical values), but thats because of the huge metal mass and special shape – alot MDs have “problems” in such situation and perhaps only a magnetometer really works here. btw. there is no difference if you search with Ground Balance minus 200, zero or plus 200, the gold detection always remains the same.
There are historical records of DIY Enthusiasts having created what is known as the “Donkey Kong Gold Hunter”. This Gold Detector uses a Nintendo Unit after many Mods.
