Trademarking Makerspace (Again)

Posted on by

A British company has filed a trademark application for the word ‘MakerSpace’. While we’ve seen companies attempt to latch on to popular Maker phrases before, Gratnells Limited, the company in question, is a manufacturer of plastic containers, carts, and other various storage solutions. These products apparently provide a space to store all the stuff you make. Something along those lines.

This isn’t the first time we’ve seen someone try to glom onto the immense amount of marketing Make: has put into the term ‘makerspace’. In 2015, UnternehmerTUM MakerSpaceGmbH, an obviously German tech accelerator based in Munich, filed an application to …read more

A Tiny Bench Power Supply

Posted on by

One of the more popular projects for beginners in electronics is a power supply. Yes, you can always go to Amazon and buy a nice power supply, but unfortunately, we haven’t set up our Amazon affiliate links yet. Instead, we’ll have to go with the next best thing and check out [Tron900]’s mini bench power supply build. It’s extremely capable and cute as a button.

The design goals for this project were to build a small and compact unit using mostly salvaged and recycled components, with all through-hole circuitry. The best guide you’ll ever find for a DIY power supply …read more

Hackaday Links: April 9, 2017

Posted on by

[Frederico Musto], one of the Arduinos in the Arduino vs. Arduino saga (which finally came to an end last September) may have fabricated his academic record. This news comes from Wired, providing documents from the registrars at MIT and NYU stating [Musto] never attended these institutions. Since this story came out, [Musto] has edited his LinkedIn, listing his only academic credential as a kindergarten in Torino, Italy.

[shininglaser] built a tinnitus machine. What’s a tinnitus machine? It’s a device that, when activated, produces this sound: eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee. [shininglaser] built this tinnitus machine out of a pair of speakers, a cardboard box, …read more

The Cubic Cyphercon Badge

Posted on by

Last week in Milwaukee was Cyphercon, Wisconsin’s premier hacker conference. You can’t do a hacker con without either an electronic conference badge or a 45 hanging off a lanyard, and the Cyphercon 2017 badge doesn’t disappoint. It’s an electronic cube, lovingly designed by the folks at tymkrs. It’s also a puzzle box with security holes and wireless communications. It’s a mesh network of badges, and one of the best conference badges we’ve ever seen.

The most obvious feature of the Cyphercon 2.0 badge is the extra dimension. From the outset, the design of this badge was a 3-dimensional cube, constructed …read more

How To Hack Your Own Password

Posted on by

[Haseeb] failed the marshmallow test as a kid. He has no self-control. He wastes a lot of time on reddit. There is a solution to this problem — simply lock yourself out of your account. The process is simple, and all you need to do is change your password to something random, change the recovery email address, and click submit. In the blink of an eye, all your imaginary Internet points vanish.

That’s the one guaranteed way to quit reddit. However, [Haseeb] wanted to hold onto those magic Internet points in the event they become worth something. This led to …read more

Hackaday Prize Entry: An Electric Longboard

Posted on by

The Hackaday Prize is in full swing, and that means we’re starting to see all the builds a few select people have been saving up for the past few months. [yowhwui] has been working on a 3D printed electric longboard for a while now, and this build is really solid. He already has over 150km on the odometer, and the 3D printed parts are still holding up.

The power for this motor comes from a 6374 brushless motor running at 192 kV. This, plus two 4S 30C 5000mAh LiPo batteries propel this longboard to speeds up to 42 km/h (2.18 …read more

Build Your Own High Power Air Cannon Out Of PVC

Posted on by

[NightHawkInLight] a.k.a. [Ben] recently built an awesome high power air cannon out of PVC pipe. PVC air cannons are great, and everyone should build one of these at some point in their life, but what really makes this build exceptional is the valve. [Ben] created a piston valve for this cannon that can be built with parts sourced from your local home supply store. Anyone can build this thing, and everyone should.

Instead of using a ball valve or other such contrivance to dump air directly from a reservoir into the chamber of this PVC air cannon, [Ben] is using …read more

Hackaday Prize Entry: WiFi In Wall Switches

Posted on by

The Internet of Things and Home Automation are the next big thing, even though we’ve had X10 switches and controllers for forty years. Why the sudden interest in home automation? Cheap microcontrollers with WiFi, ZigBee, and Z-wave, apparently. For this Hackaday Prize entry, [Knudt] is building a WiFi switch, meant to be retrofitted into any Euro wall switch.

There are three parts of [Knudt]’s WiFi wall switch, each of them with different requirements. The top layer is the switch itself and a small OLED display. These switches are really two small capacitive switches, which means there’s no reason to go …read more

The Best Of VCF East

Posted on by

Last weekend was the Vintage Computer Festival East in Wall, New Jersey. While this yearly gathering of nerds nerding out on old computers might be a bit too obscure for some, there are always amazing exhibits of actual historical importance. A few Enigma machines showed up, and the rarest Commodore goodies made an appearance. We saw the pre-history of Hackaday and ‘maker’ culture with Southwest Technical Products Corporation, and found out it was probably, possible to build a RepRap in the 80s. You can’t know where you’re going unless you know where you came from, and even though the old …read more

VCF: Popular Electronics And Southwest Technical Products Corporation

Posted on by

Hackaday owes a lot to the hobbyist electronics magazines of yesteryear. Back in the day, Popular Electronics and Radio-Electronics would publish projects and articles about DIY electronics – more or less the same editorial purview we hold today. Some of these projects would become full-fledged products, and you need only look at the Altair for what can happen at this confluence of publishing and engineering.

One of the more popular companies to come out of these hobbyist trade magazines was SWTPC, or Southwest Technical Products Corporation. This was the company that brought one of the first microcomputers to the masses …read more
