Electronic Projects For Beginners
I made a guide for those people who are still starting with their electronics hobby. I started connecting wires, batteries, bulbs, buzzers and motors when I was 4 years old . Now that I am 13 years old, I now have a good amount of experience to build complicated electronic circuits. Learning electronics isn't that easy but if you put love and passion to it, I assure you that you would enjoy building your own experiments.
How to make a tool set
Life without tools is barbaric. But even simple tools can be expensive in rural parts of developing countries. Import duties bump the costs up higher than they are in the States or elsewhere, and sometimes only low-quality brands are available anyway. So, to hold off future barbarians, we'd like to show how to build a simple tool set on a very low budget. Larry Bentley, the man who figured out how to make these tools, said a wise thing: "Without tools, kids don't take stuff apart, and without taking stuff apart, you don't learn how things work." These tools, Bentley says, could be in the hands of the next William Kamkambwa,who made a working wind power generator from backyard scraps in a village in Malawi.
Schauberger(eng.)
The author of the article gives a brief description of the real design of aircraft engine. Probably, this design is not similar to Schauberger's one. However the very appearance of some ideas is rather interesting. Different people in different places and time come to the same conclusions. Whether people think in a common way, or Nature laws are the same. Could you believe that the author of the article has never read or heard about Schauberger's works (I mean his engine, which operates on environment energy and has levitation properties)?
Top 10 DIY Tech Gifts
@keyboard-vomit: Yeah, but wouldn't it be awesome if some of our not so tech friends actually attempted (and accomplished) one or more of these feats? I mean, when "it's the thought that counts," shouldn't it be a thought about something we'd actually appreciate. Then again, maybe socks are your thing. ;) @HunterShoptaw: That they are, I'm wanting some socks with an integrated HDD, and some USB connectivity. @HunterShoptaw: The thought does count, but it sure would be nice if they enjoyed the gift too.
How Circuits Work"
Have you ever wondered what happens when you flip a switch to turn on a light, TV, vacuum cleaner or computer? What does flipping that switch accomplish? In all of these cases, you are completing an electric circuit, allowing a current, or flow of electrons, through the wires. An electric circuit is in many ways similar to your circulatory system. Your blood vessels, arteries, veins and capillaries are like the wires in a circuit.
Wimoto motes - Your Sixth Sensor
Wimotos are a family of small, wireless sensors for your iPhone, iPad, Android, Linux or Raspberry Pi device that measure environmentals such as ambient temperature, humidity, light, soil moisture, soil temperature, object temperature, human presence and movement. They last for about a year on a single battery and don't require an Internet connection to work. You can upload your data to our cloud service for analysis via our free app, or use the optional Wimoto Cloud Cube to do it for you in realtime via Wifi.
34 DIY headboard ideas
The headboard is now looked at as a mainly decorative element in our bedrooms. As it usually happens, it all started from a practical reason/purpose.The headboard, a piece of furniture that is attached to the head of the bed, was initially an element that isolated sleepers from drafts and cold. Back then the buildings were less insulated and thus such a feature was needed.
Circuit Diagrams
After reading this section you will be able to do the following: Explain what circuit diagrams are used for. Identify what the symbols in the circuit diagrams stand for. Circuit diagrams are a pictorial way of showing circuits. Electricians and engineers draw circuit diagrams to help them design the actual circuits.

2KW DIY Solar panels made of pop cans for home solar heating
At the end, the solar absorber is painted black and placed in the diy solar panels casing. The casing is covered with plexiglass that we attach to the frame and thoroughly corked with silicone. Polycarbonate / plexiglass is slightly convex in order to gain greater strength. You can see installed solar absorber without plexiglass in picture 18.
Circuit Symbols and Circuit Diagrams
Thus far, this unit of The Physics Classroom tutorial has focused on the key ingredients of an electric circuit and upon the concepts of electric potential difference, current and resistance. Conceptual meaning of terms have been introduced and applied to simple circuits. Mathematical relationships between electrical quantities have been discussed and their use in solving problems has been modeled. Lesson 4 will focus on the means by which two or more electrical devices can be connected to form an electric circuit.
