Kevin Kelly and I had a great time talking to Limor Fried, an MIT engineer and the founder of Adafruit, a one-stop shop for makers to buy electronics kits and components as well as learn and share ideas related to electronics prototyping. Limor told us about the giant pick-and-place and stencil printers she uses at Adafruit to make her kits at her New York City factory.

If only all computer interfaces were as gloriously sci-fi as this excellent "DIY Overhead Control Panel" hand-built by a maker called Smashcuts. It features a slew of LEDs and 100 programmable buttons and switches that activate shortcuts on his PC, open apps, control volume and screen preferences, etc. Read the rest
Here's episode 6 of Circuit Playground, a charming show that teaches kids about electricity. It's produced by our friends at Adafruit. In this episode, Ladyada teaches Adabot about electrical grounding.

For three years, makers have hacked together some terrific and janky DIY Raspberry Pi cases (like these). Finally, Ebon Upton and the Raspberry Pi Foundation have produced their own official Raspberry Pi case. Read the rest
When electronics retailer Radio Shack filed for bankruptcy, the chain proposed selling customers' personal data to raise cash and repay creditors. That's not gonna happen, and the news is seen as a win for the right to privacy. Read the rest
When I was one of the editors at Make: Books, one of the projects I was proudest to have helped conceive of and edit was Charles Platt’s Make: Electronics (which has now been a best-seller for years). Growing up being absurdly visual and suffering from mild dyslexia, I found it incredibly difficult to learn electronics using the books of the day. They were usually very poorly written, with bad editing, dark and dreary photos, and crude diagrams. Forrest Mims’ 1983 Getting Started in Electronics, beautifully hand-drawn on graph paper, with succinct and clear text and playful examples, was a revelation to me.
For Make: Electronics we wanted to create a Getting Started for the early 21st century – well-written, beautifully photographed and illustrated, and in high-quality, full-color. Charles Platt and Make: delivered on that promise, in spades, with Make: Electronics and its follow-up volume, Make: More Electronics. And Charles continues to knock it out of the park with Encyclopedia of Electronic Components, currently in two volumes, with a third on the way.
Volume 1 covers batteries, power supplies, motors, resistors, capacitors, inductors, switches, encoders, relays, diodes, transistors, and more. Each entry describes what it does, how it works, variants on the component, how to use it, and what can go wrong with it. Each entry is illustrated with well-shot photos (the components are shot on a graph paper background, so you can get some idea of their size), charts and graphs, and cut-away diagrams. The writing is very approachable while not shying away from technical rigor. Read the rest
Mike Harrison has been experimenting with tiny flexible LED filaments found in LED bulbs that mimic incandescent bulbs. He came up with this cool light cube and a very bright clock display. Read the rest
Charles Platt shows you how to build a noise-detecting siren that stuns rude shouters into silence.
[Video Link] Amanda Wozniak hosts the latest Circuit Playground video, which is about the diode, a common and useful electronic component.
The videos are based on the A-Z coloring book that Adafruit Industries published last year. So far, they've released 3 episodes: A is for Ampere, B is for Battery, and the latest, C is for Capacitor. Read the rest
Circuit Playground is a cute and informative video series created to teach kids (and everyone else) about electronics. The videos are based on the A-Z coloring book that Adafruit Industries published last year. So far, they've released 3 episodes: A is for Ampere, B is for Battery, and the latest, C is for Capacitor. I learned quite a bit by watching them.

Joshua Lifton is one of the founders of Crowd Supply, a company that crowdfunds around products. They take a very different approach to preparation, funding, and follow-up than Kickstarter. Kickstarter just announced that it had crossed $1bn in pledges in its five-year lifetime. Of that, it's disbursed nearly $850m. It's on track to facilitate perhaps half a billion in 2014 alone.
The name Kickstarter may be used interchangeably with the term crowdfunding, and it is the 800 lb. gorilla in the space. (Watch out for the shipping charges on that gorilla, especially internationally.) But in its wake, hundreds of millions of dollars are being raised from all sorts of other sites which fill in important aspects of ecosystem, and Crowd Supply is one of them.

I learned resistor color code values as a kid by memorizing a racist mnemonic that a friend taught me. Today, there's a much better way. It's an app called Mho's Resistance, and it was created by our friends at Adafruit Industries!

Joel Murphy (co-creator of the nifty PulseSensor, an Arduino sensor that detects pulse) teamed up with Conor Russomanno to create the OpenBCI, a Bluetooth-enabled, Arduino-compatible, 8-channel EEG platform that gives you access to high-quality, raw EEG data. What can you do with it? Biofeedback, DIY sleep research, creating art, controlling systems, and more.
They've got a Kickstarter going to fund it. Read the rest
Huawei, the Chinese electronics giant that was accused of being "a security risk" in a paper by the House Intelligence Committee (its chair, Mike Rogers [R-MI], said "find another vendor if you care about your intellectual property, if you care about your consumers' privacy, and you care about the national security of the United States of America") has come out swinging in a new cybersecurity paper.
In the paper's foreword, the company's deputy chair Ken Hu writes:
[Huawei] never received any instructions or requests from any government or their agencies to change our positions, policies, procedures, hardware, software or employment practices or anything else, other than suggestions to improve our end-to-end cyber security capability.
“We can confirm that we have never been asked to provide access to our technology, or provide any data or information on any citizen or organization to any Government, or their agencies."
Unlike the companies that were on the target of the NSA and GCHQ's BULLRUN/EDGEHILL programs, which spent $250,000,000 a year to subvert security standards, and to convince western electronics companies to sabotage their own security.
