Anker makes good stuff. Their 60-Watt 10-port USB charger can charge up to 2.4 amps per port (12 amps maximum). If you live with more than a few people, this can come in handy. It's on sale at Amazon for $33.59. Read the rest
Peegar is an Arduinio-style electronics kit that you design programs for by dragging and dropping Scratch-style objects around in a browser; when you're done, the program is converted to a brief snatch of sound that you transmit through the board by plugging a standard audio cable into your device's headphone jack.

Produced by Bell Labs in 1973, The Far Sound looks at the latest developments it telephony, electronics, and computers. The intro has Peter Max-ish graphics and a song that sounds like a Partridge Family instrumental.
1973, the year this film was made, was a very exciting time to be at Bell Labs. Telstar was under development. BellComm was about to be spun off, to work with NASA on the moon project. Technologies involving the transistor, laser, and the solar cell were underway. Scientists were just starting to explore what a computer was and what it might accomplish. In the middle of this wave of innovation was the Bell System’s core business—providing telephone service to almost the entire country.
Anker generally makes high quality electronic gear, and judging by the reviews on Amazon, the tiny SoundCore Nano Bluetooth speaker is no exception. It's got a battery life of 4 hours, and can be recharged with the included Micro USB charging cable (which also can be used as a way to connect the speaker to a computer instead of Bluetooth).

“The designing, building and programming of the GM01 unit took more than one year of daily work,” says the maker, who is a fan. “Finishing it with the desired quality was a huge odyssey.”
Damn. This thing is no joke. Read the rest
I have a copy of Electronics for Kids: Play with Simple Circuits and Experiment with Electricity, by Oyvind Nydal Dahl. It's a full-color introduction to electronics, and is useful for kids and adults who want to get started in hobbyist electronics. Right now, this 328 page book is on sale for just $11 on Amazon.

Why do the lights in a house turn on when you flip a switch? How does a remote-controlled car move? And what makes lights on TVs and microwaves blink? The technology around you may seem like magic, but most of it wouldn't run without electricity.
Electronics for Kids demystifies electricity with a collection of awesome hands-on projects. In Part 1, you'll learn how current, voltage, and circuits work by making a battery out of a lemon, turning a metal bolt into an electromagnet, and transforming a paper cup and some magnets into a spinning motor. In Part 2, you'll make even more cool stuff as you:Solder a blinking LED circuit with resistors, capacitors, and relays Turn a circuit into a touch sensor using your finger as a resistor Build an alarm clock triggered by the sunrise Create a musical instrument that makes sci-fi sounds
Then, in Part 3, you'll learn about digital electronics--things like logic gates and memory circuits--as you make a secret code checker and an electronic coin flipper. Finally, you'll use everything you've learned to make the LED Reaction Game--test your reaction time as you try to catch a blinking light!
With its clear explanations and assortment of hands-on projects, Electronics for Kids will have you building your own circuits in no time.
Fumihito Taguchi's fantastic collection of vintage portable record players, including the wonderful specimens seen here, will be on display at Tokyo's Lifestyle Design Center from July 30 to August 28. See more at this Fashion Press post and in Taguchi's book "Japanese Portable Record Player Catalog," available in the US from my favorite vinyl soulslingers Dusty Groove. (via #vinyloftheday)
Encyclopedia of Electronic Components Volume 3: Sensors

I had to remove the SSD from an elderly MacBook Air, but the tiny little screw on it was stuck on good. The appropriate Torx driver stripped it, and two flatheads snapped in the hole that remains. Here's the easy way. Read the rest
Each circuit depicts an original, traced and hand-drawn schematic created by Forrest Mims for his iconic books Getting Started in Electronics, and the Engineers’ Notebook series. Every board includes a description of how it works, in Mims’ handwriting, on the reverse side.
Alongside the schematic is the circuit itself. Paired with the components you need to build up timeless examples such as the Dual-LED Flasher, the Stepped Tone Generator, and the Bargraph Voltage Indicator, each board is carefully designed for easy assembly recreating the wonder of learning how electronics work— whether it’s your first soldering project or your fifty-thousandth.
Here's Star on the O'Reilly Hardware podcast talking about designing beautiful circuit boards:
Are they Alligator leads or Crocodile clips?
This $4 set certainly comes in handy when playing with our Makey Makey, and unsurprisingly have become standard kit when trouble-shooting electrical gremlins on my motorcycle.
Also useful for extending the reach of a multi-meter.
