This article was suggested by Tom Greene and his team at STEM Courses.
We are all living in such a digital age where we rely on electronically powered objects to help get us through our daily tasks. Ever wonder what would happen if that phone didn't work or that lamp couldn't turn on? Electricity is all around us and it is growing everyday. It's important for children and adults to take the time to learn about the history of electricity and how it operates. Learning basic electrical skills can help you win a science fair or help you accomplish tasks around the house that you would normally reach out to a professional for.
Topics include:
* A Brief History of Electricity
* The Lightbulb
* Television
* Telephone
* Solar Energy
* Windmills
* Steam
And many more!

Device Plus is a website created by ROHM, a semiconductor and electronic parts manufacturer, to deliver useful information to engineers who love creating things and aspiring engineers.
Device Plus was created with one goal in mind: making the engineer’s life more fun. Even though we said “fun”, it’s not just about entertainment.
This can be deepened your knowledge in on one particular field, getting inspiration from your mentors, or even having the inspiration to change the world.
The articles presented on Device Plus are dealing with various topics related to the electronic kits and the engineer’s life.
We will talk about topics centered on “technology” such as people, events, hacks/tips, tools, devices, and so on. We will go in-depth, but without forgetting to have fun.
Finally, we hope to attract and help people who share a passion for Electronics and Mechatronics.

Hackaday serves up Fresh Hacks Every Day from around the Internet. Our playful posts are the gold-standard in entertainment for engineers and engineering enthusiasts.
We are taking back the term “Hacking” which has been soured in the public mind. Hacking is an art form that uses something in a way in which it was not originally intended. This highly creative activity can be highly technical, simply clever, or both. Hackers bask in the glory of building it instead of buying it, repairing it rather than trashing it, and raiding their junk bins for new projects every time they can steal a few moments away.
Our front page is a mix of hacks from around the community as well as our own original content. We strive to promote the free and open exchange of ideas and information. We educate those just learning the art of Hack, and provide inspiration for the seasoned veterans. Don’t be shy; if you want to show off your project, or have found something cool of someone else’s that deserves sharing, send us a link!

PCB Design - Resources for PCB Designers
PCB design can be frustrating, time consuming, and very difficult to figure out how to get started. We've broken printed circuit board design into 3 sections: schematic capture, pcb footprints, and pcb layout.
These 3 sections will provide you with the resources needed to tackle your first printed circuit board design.
Our pcb design guide will also help you figure out which is the best pcb design software to use, whether your project is a hobby or a commercial product.

TinyCircuits is a maker of tiny open-source electronics that let you create your own miniature electronic projects.
Our main product is the TinyDuino - an Arduino compatible platform the size of a US Quarter.
The TinyDuino platform is completely modular and works like tiny electronic LEGOs, so you can easily add complex functions, like GPS, WiFi, motor control or graphics displays to your projects just by plugging the expandable modules (called TinyShields).
We serve the Maker community and are Maker's ourselves - we make all TinyCircuits products in our factory in Akron, Ohio, USA, and take great care to make sure the products we ship out are the highest quality.
