The Voice of Dave, Now In Toy Form

Posted on by

Dave Jones is something of a celebrity in the hacker and maker communities, bringing his considerable knowledge and experience to bear on a wide variety of electronic and engineering topics. His unique voice and candor have endeared him to many, and he’s one of the more quotable YouTubers currently on the scene. With that in mind, [Andrei Aldea] decided to build a Speak ‘n’ Say in his honor.

The build was inspired by an earlier effort by [Ben Heck]. [Andrei] started by disassembling the Speak ‘n’ Say, and determined that there was a simple button matrix that would allow the …read more

PCB art is getting better and better every year. This year, though, is knocking it out of the park. In March, [Andrew Sowa] turned me into money. More recently, [Trammell Hudson] has explored the layers of OSH Park soldermask and silk to create a masterpiece. Now, we’re moving up to full-blown art. [Blake Ramsdell] worked with OSH Park to create a full panel of art in gold, fiberglass, soldermask, and silkscreen. It’s 22×16 inches, and it’s fantastic.

There’s an independent Hackaday meetup going down in Hong Kong this week. The subject of the meetup will be vacuum systems for electron …read more

It’s been about a year and a half since the Batteroo, formally known as Batteriser, was announced as a crowdfunding project. The premise is a small sleeve that goes around AA and AAA batteries, boosting the voltage to extract more life out of them. [Dave Jones] at EEVblog was one of many people to question the product, which claimed to boost battery life by 800%.

Batteroo did manage to do something many crowdfunding projects can’t: deliver a product. Now that the sleeves are arriving to backers, people are starting to test them in the wild. In fact, there’s an entire …read more

Feel Better About Yourself With These Ugly Repairs

A fun thread over at the EEVblog forum starts off with [TerraHertz]’s triangle-peg, square-hole capacitor repair job and goes entertainingly down-hill from there.

Everything from horrifying eBay purchases to work (horror) stories can be found in this thread. But you can learn something too. Did you know the correct way to fix a mercury switch stored in the incorrect orientation is to whack it against a table really hard?

We enjoyed the cigarette box shroud used to fix a graphics card with a defective fan. We’re still not sure about the person who managed to Dremel bits off a graphics …read more

Hackaday Links: April 3, 2016

April Fool’s Day was last Friday, and the Internet was garbage for a day. Our April Fool’s prank was amazing, and in a single day garnered more views than the Raspberry Pi 3 launch announcement from a month prior. There just might be a market here for Apple. Here’s a short roundup of some of the best electronics April Fool’s posts:

  • Introducing the Implantuino, an Arduino designed for subcutaneous insertion.
  • Everyone needs a plumbus. First they take the dinglebop and smooth it out with a bunch of schleem.
  • Virtual Reality? That’s overhyped, and just a fad. How about Real Reality?
