The Higgs Boson – A one page explanation, read them all – they’re all good… [via]

What a great idea for a website. An entire list of things that are complex explained in one page and the best ones are chosen. We can think of a few dozen topics that could use this

In 1993, the UK Science Minister, William Waldegrave, challenged physicists to produce an answer that would fit on one page to the question ‘What is the Higgs boson, and why do we want to find it?’ Here are the winning entries!

While books of phone schematics are common place in Shenzhen (and probably throughout China),an interesting website came up in my search results for something completely unrelated. Ever wonder how mobiles phones are designed to pack so much functionality into increasingly smaller packages? Have a look at cellphonediagram.com and you should find a lot of interesting material to learn from.

Get Started with FPGAs‏, from Jeri… [via]

This is a simple FPGA board I’ve been using a project. I think this would be a great board for someone just getting started with FPGA’s.

This is just a quick video showing that you can power an AVR project from a fried servo or an old emergency cell phone charger.

RiderScan – Manage horses with Adafruit gear! RFID barn management system made for Misty Brae Farm of Virginia…

This is a demo of the RiderScan system; an RFID barn management system made for Misty Brae Farm of Virginia. The system is comprised mostly (~85%) of electronic goodies from Adafruit Industries (http://www.adafruit.com/) and cobbled together using an Arduino Mega Protoshield and lots of Acrylic.

Your adorable robotics for the day: GRITS (the Georgia Robotics and Intelligent Systems lab) have trained their Khepera robots to move in formation, and then to come together and form landing pads for their airborne siblings, the Quadrotors (dun dun dun!). You can read all about the algorithm used to control these robots at Ted MacDonald’s page. Or you can just watch these two videos over and over and over again with a mixture of affection, admiration and fear.

Micro SD card Tutorial How to add lots o’ storage with microSD (and SD) cards. If you have a project with any audio, video, graphics, data logging, etc in it, you’ll find that having a removable storage option is essential. Most microcontrollers have extremely limited built-in storage. For example, even the Arduino Mega chip (the Atmega2560) has a mere 4Kbytes of EEPROM storage. There’s more flash (256K) but you cant write to it as easily and you have to be careful if you want to store information in flash that you don’t overwrite the program itself!

We live in a world where the accumulation of knowledge is exponential over time, and where the ability to continuously learn and make sound judgments is essential to survival. Formal education ought to play an important role in preparing individuals to succeed in this environment, but many traditional modes of education actually discourage development of independent thinking skills necessary for success.

The most important thing any educator can impart to a student, in any context, is the ability to teach themselves. When teachers dispense knowledge to students in the traditional lecture format — where students passively watch and listen — they deny students deep interaction with the subject matter. Furthermore, instructor-centered pedagogy assumes and reinforces the debilitating notion that education can only happen in the presence of a superior: You (the student) need me (the teacher) in order to learn.

Photovoltaic polarizers enable devices to be powered by sunlight

New technology developed by researchers at the UCLA Henry Samueli School of Engineering and Applied Science could finally help solve the problem of smartphones or laptops running down when there is no access to an electrical outlet.

UCLA engineers have created a novel concept for harvesting and recycling energy for electronic devices — one that involves equipping these devices’ LCD screens with built-in photovoltaic polarizers, allowing them to convert ambient light, sunlight and their own backlight into electricity. [via]
