There will be no special badges for DEFCON. Everyone will still have badges — and our expectations are tempered because of the one year on / one year off schedule for electronic badges — there just won’t be mind-bending puzzles wrapped up in the official badges. What this means: it probably won’t matter if you’re late for linecon, and someone in the DEFCON hive mind still has a Facebook. Also, DEFCON is canceled.

In the past, we have decried the very existence of fidget spinners. It’s what the kids are into, after all. However, an electronic fidget spinner is …read more

Hackaday Prize Entry: Modular Circuits with SnapBloksScreen Shot 2017-05-29 at 11.35.35 AMnerdyjb

Sun, 25 Jun 2017 20:00:15 +0000

[Ekawahyu Susilo]’s twist on the modular circuit kit, SnapBloks helps you create circuits by stacking components on top of each other with the help of three magnetic contacts that not only keep the modules stuck together but also deliver power, ground, and data to each part.

[Ekawahyu] envisioned it as a prototyping kit, used to whip together an idea without a lot of hassle. It could also be an educational aid, used to teach Arduino coding while skipping the confusing tangle of wiring. You can stack a sound module on top of a power module to make a buzzer, or …read more

Another Helping Hands Buildstationwd5gnr1

Sun, 25 Jun 2017 17:00:30 +0000

[Punamenon2] wanted a soldering station with integrated helping hands. He couldn’t find one, but he decided it would be a good 3D printed project. In all fairness, this is really 3D printing integrating several off-the-shelf components including a magnifier, a soldering iron holder, a soldering iron cleaner, a couple of “octopus” tripods, and some alligator clips. Total cost? Less than $30.

In addition to holding the Frankenstein monster together, the 3D printed structure also provides a storage tray with special sloped edges to make removing small screws easier.

We were a bit surprised at the use of the cell phone …read more

iPad, not Flux Capacitor, Brings DeLorean Back to the Futureksv5CgMdpsm64

Sun, 25 Jun 2017 14:00:06 +0000

Add a flux capacitor and a Mr. Fusion to a DeLorean and it becomes a time machine. But without those, a DeLorean is just a car. A 35-year old car at that, and thus lacking even the most basic modern amenities. No GPS, no Bluetooth — not even remote locks for the gullwing doors!

To fix that, [TheKingofDub] decided to deck his DeLorean out with an iPad dash computer that upgrades the cockpit experience, and we have to say we’re impressed by the results. Luckily, the space occupied by the original stereo and dash vents in the center console is …read more

Animated Bathroom SignmainALTrestroomsignlewinday

Sun, 25 Jun 2017 11:00:00 +0000

Once upon a time, pants were created. After a while, women were allowed to wear them too. This has made a lot of people happy and been widely regarded as a good thing. There is a problem, however – bathroom signage is largely predicated on the idea that there are two rigid genders which all humans must be sorted into, and they’re defined by whether you’re wearing pants or a dress. [Robb Godshaw], among others, disagrees with this, and set about building a gender fluid bathroom sign.

The project seeks to exploit the traditional symbols of “male” and “female” – …read more

Dirty Now Does CablesScreen Shot 2017-06-23 at 9.33.15 AMnerdyjb

Sun, 25 Jun 2017 08:00:16 +0000

PCB makers Dirty made a name for themselves in the prototype PCB biz, with a convenient web form and numerous options for PCB color, thickness, layers, silk screening, and so on. Now they’ve branched out into custom cabling with Dirty Cables.

You can design it yourself by dragging wires and connectors out of a sidebar and arranging them on a workspace, deciding which wire goes to what pin of the connector. Your choices for wires include various gauges and ribbon configurations. You choose a color (they have eleven) select connectors and drag those out too–choose from 17 cable-to-cable and cable-to-board …read more

Listen to your Bodyemgwd5gnr1

Sun, 25 Jun 2017 05:00:14 +0000

[John Miller] has the perfect response next time he complains about an ache or pain and one of his friends says, “You should listen to your body!” As you can see in the video below, he already does. Using two 9V batteries and some instrumentation amplifiers, [John] built an electromyography (EMG) rig.

If you haven’t heard of EMG, think of EEG or EKG, but for muscles instead of your brain or your heart. The LT1167 amplifier is well-suited for this application and even has a data sheet showing how to create an EMG circuit. [John] also used some more garden-variety …read more
