Magnetic Circuits Are More Attractive Than Breadboarding via hack a day

This might be an interesting learning project for young ones who are just getting started. Sort of like an extension of Lego thinking. The space required to build things is a bit large, especially compared to a breadboard, but might be more understandable to someone who is new to electronics. Building the tiles adds another, hands-on, level to the learning that is a great combination with the electronics concept learned, too. This is a good, High-Tech/High-Touch project.— Douglas
 

Let’s face it, breadboarding can be frustrating, even for advanced electronics wizards. If you have an older board, you could be dealing with loose tie points left from large component legs, and power rails of questionable continuity. Conversely, it can be hard to jam just-made jumper wires into new boards without crumpling the copper. And no matter what the condition of the board is, once you’ve plugged in more than a few components, the circuit becomes hard to follow, much less troubleshoot when things go pear-shaped.

In the last twenty years or so, we’ve seen systems like Snap Circuits and Little Bits emerge that simplify the circuit building process by making the connections more intuitive and LEGO-like than even those 160-in-1 kits where you shove component legs between the coils of tight little springs. You will pay handsomely for this connective convenience. But why should you? Just make your own circuit blocks with cardboard, magnets, and copper tape. It should only cost about 10¢ each, as long as you source your magnets cheaply.

This DIY domino clock tells the time using three LED-lit tiles via Arduino Blog

After coming across Carbon Design Group’s Domino Wall Clock, which uses electronic magnetic coil motors to reveal white dots, Instructables member “Kothe” decided to create a simplified version of their own. The clock is comprised of three custom dominoes — the first tile for hours, the second and third for minutes. Unlike its inspiration, Kothe’s device uses addressable RGB LEDs as dots that allow for a variety of colors to shine through.

Onion Pi makes your web traffic anonymous via Open Electronics

Hmmm, might be an easy (and relatively cheap) way to play around with Tor and learn a bit more about this anonymizing service. -- Douglas Adafruit’s Onion Pi is a Tor proxy that makes your web traffic anonymous, allowing you to use the internet free of snoopers and any kind of surveillance. Follow Adafruit’s tutorial on setting up Onion Pi and you’re on your way to a peaceful anonymous browsing experience. Tor is an onion routing service – every internet packet goes through 3 layers of relays before going to your destination. This makes it much harder for the server you are accessing (or anyone snooping on your Internet use) to figure out who you are and where you are coming from.
