This insane DIY fan-made Daft Punk helmet even comes with WIFI

1 - First GM01 Unit My hand-made robotic Daft Punk helmet

LoveProps has indeed crafted a “Perfect Daft Punk Helmet,” and I dare say it's better than the original worn by the band.

“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

Great deal on Electronics for Kids book

efk

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.

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

Star Simpson is designing classic circuits from Forrrest Mims' "Getting Started in Electronics"

circuitclassics8-1_jpg_project-main-8

The talented engineer Star Simpson is designing circuits from in Forrest M. Mims' terrific 1980s electronics books published by Radio Shack. They look great!

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: Read the rest

Handy $4 set of 10 test leads

71VDuMmqRvL._SL1500_

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.

The best book on learning electronics just got better

me-0

When Make: Electronics was published about five years ago, it was widely hailed as the greatest book about learning electronics ever written. With beautiful photos, easy-to-read schematics, clear, jargon-free text, and dozens and dozens of fun and educational projects, author/illustrator Charles Platt made a book that has ended up in every makerspace and library I've visited.

A few weeks ago the Second Edition of Make: Electronics came out, and it's even better than the first edition. Charles rewrote the text, replaced the photos of breadboarded circuits with diagrams showing component placement, included new projects, added new photographs with a ruled background to indicate the scale of tools and components, and included a chapter on Arduino.

This is the book to get if you want to learn electronics.

(Disclosure, I was Charles' editor when I was editor-in-chief of MAKE) Read the rest

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.
