This idea is both for indoor and outdoor use, depends on how you could modify or enhance it. The important reason you ought to build this circuit is to learn building non-ic oscillators, this trains you on L, C, R and Transistor Switching. – delabs
With a handy metal detector you can check beforehand whether there are metal objects in a wall, ceiling or floor. An LED indicates if a metal object is in the vicinity and keeps your simple home projects, simple and safe.
A firm based at Greenbackville, Virginia provides parts and kits for Amateur Radio applications. Products include data and audio cables for APRS and packet radio. They also offer simple serial communications testing and monitoring tools.
A spinoff of the original LED chaser. It’s based on the PIC16F84 clocked at 10MHz. This is a basic model that can be adapted to many applications. They are much brighter and can be seen during the day better.
The main goal of this project is to develop a miniature mobile robot for educational purposes at university level.
To help the creation of a community inside and outside EPFL, the project is based on an open hardware concept, where all documents are distributed and submitted to a license allowing everyone to use and develop for it.
This project has been started at the Ecole Polytechnique Fédérale de Lausanne as collaboration between the Autonomous Systems Lab, the Swarm-Intelligent Systems group and the Laboratory of Intelligent System.
“The robot should cover a large spectrum of educational activities and should therefore have a large potential in its sensors, processing power and extensions. Potential educational fields are, for instance, mobile robotics, real-time programming, embedded systems, signal processing, image or sound feature extraction, human-machine interaction or collective systems… “
Excellent Online Educational Pages at Exeter. Students and Teachers can get ideas on how to enhance and enrich the Science Education Process.
A Sound understanding of Physics and Chemistry is needed for stepping into “Electricity and Magnetism”. We have to move young minds into Electronics even before High School, as a part of Science itself.
Here is a Google Science Fair Experiment in which even computers, electronics and coding is used in a Historic, Multi-Technology, Chain Reaction. This could be real or simulated, i am not sure, but it makes Science Adventurous.
