Filaween 2.0 is Go

[Thomas Sanladerer] is at it again: testing all of the 3D-printer filaments that are fit to print (with). And this year, he’s got a new and improved testing methodology — video embedded below. And have a search for “filaween2” to see what he’s reviewed so far. There’s some sexy filaments in there.

We really love the brand-new impact strength test, where a hammer is swung on a pivot (3D printed, natch), breaks through the part under test, and swings back up to a measurable height. The difference in swing height reflects the amount of energy required to break the test …read more

DEF CON Badgelife: The ESP Rules All

Badgelife is the celebration of independent hardware creators, working for months at a time to bring custom electronic badges to conferences around the world. This year at DEF CON, Badgelife is huge. It’s not just because this year was supposed to feature a non-electronic badge, and it’s not because the official badge imploded last month — Badgelife is all about people spending most of the year designing, and manufacturing hardware, culminating in one very special weekend.

[Garrett] owns Hacker Warehouse, a store providing all kinds of neat hacker tools ranging from software-defined radios to lock pick sets to side channel …read more

Book Review: The Art Of The Patent

In bringing suitable illustrations to our articles, we Hackaday scribes use a variety of sources that offer images featuring permissive licences. Among the usual free image libraries there is one particularly rich source, the line drawings contained within the huge archives of patents granted by the various countries around the world. These are the illustrations used as part of the patent itself to describe the working of the patent being claimed. We use them because though the items they depict are legally protected from copying by the patents they are part of, they as part of the patents themselves are …read more

Scope Review: Keysight 1000 X-Series

A few weeks ago we published an article on the newly released Keysight 1000 X series. A scope that marks Keysight’s late but welcome entry into the hacker-centric entry-level market. Understandably, this scope is causing a lot of excitement as it promises to bring some of the high-end pedigree of the well-known 2000 X and 3000 X series down to a much affordable price. Now couple that with the possibility of hacking its bandwidth lock and all this fuss is well justified.

[Dave Jones] from the EEVblog got his hands on one, and while conducting a UART dump saw the …read more

Antenna Analyzer is a Lab in a Box

There was a time when the measure of a transmitting radio antenna was having it light an incandescent bulb. A step up was a classic SWR/Power meter that showed you forward and reflected power. Over the years, a few other instruments have tried to provide a deeper look into antenna performance. However, the modern champion is the antenna analyzer which is a way of measuring vector impedance.

[Captain Science] did a review of an inexpensive N1201SA analyzer. This device is well under $200 from the usual Chinese sellers. The only thing a bit odd is the frequency range which is …read more

Review: Hammer-Installed Solderless Raspberry Pi Pin Headers

A few days ago we reported on a new product for owners of the Raspberry Pi Zero, a set of solderless header pins that had a novel installation method involving a hammer. We were skeptical that they would provide a good contact, and preferred to stick with the tried-and-trusted soldered pins. It seems a lot of you agreed, and the comments section of the post became a little boisterous. Pimoroni, the originator of the product, came in for a lot of flak, with which to give them their due they engaged with good humor.

It’s obvious this was a controversial …read more

Books You Should Read: The Hardware Hacker

There’s no one quite like Andrew ‘Bunnie’ Huang. His unofficial resume begins with an EE degree from MIT, the author of Hacking the Xbox, creator of the Chumby, developer of the Novena, the first Open Source laptop, and has mentored thousands of people with dozens of essays from his blog.

Above all, Bunnie is a bridge across worlds. He has spent the last decade plying the markets of Shenzhen, working with Chinese manufacturers, and writing about his experiences of taking an idea and turning it into a product with the help of Chinese partners. In short, there is no …read more
