SCiO “Pocket Molecular Scanner” TeardownSCIO_Teardown_Images-13dp2cnk

Thu, 20 Jul 2017 11:00:03 +0000

Some of you may remember the SCiO, originally a Kickstarter darling back in 2014 that promised people a pocket-sized micro spectrometer. It was claimed to be able to scan and determine the composition of everything from fruits and produce to your own body. The road from successful crowdsourcing to production was uncertain and never free from skepticism regarding the promised capabilities, but the folks at [Sparkfun] obtained a unit and promptly decided to tear it down to see what was inside, and share what they found.

The main feature inside the SCiO is the optical sensor, which consists of …read more

Old Intercom Gets Googled with Raspberry Pi and AIY HatFCRLSPBJ52Q2I1Idpsm64

Thu, 20 Jul 2017 08:00:15 +0000

Old Radio Shack intercom; brand new Google Voice interface for a Raspberry Pi. One of these things is not like the other, but they ended up together in this retro-look Google Voice interface, and the results are pretty slick.

The recipient of the Google hive-mind transplant was one of three wireless FM intercoms [MisterM] scored for a measly £4. Looking much as they did when they were the must-have office tool or home accessory for your modern mid-80s lifestyle, the intercom case was the perfect host for the Pi and the Google AIY hat. Only the case was used — …read more

Take Control Of Your Cheap Laser Cutterk40-whisperer-featuredjennylist

Thu, 20 Jul 2017 05:00:00 +0000

The relatively inexpensive K40 laser cutter/engraver machines from China have brought laser cutting to the masses, but they are not without their faults. Sure, they’re only powerful enough for the lightest cutting tasks, but on top of that, their bundled software is inflexible and disappointing. If your workshop or hackspace has one of these machines languishing in the corner, then the release of a new piece of software, K40 Whisperer from [Scorch], is an interesting and welcome development.

He tells us that the reverse engineering process required to understand the K40’s protocol was non-trivial, given that it does not use …read more

Lethal LED Lantern Leaks Lotsa ‘Leccylethal-lamp-featuredjennylist

Thu, 20 Jul 2017 02:00:00 +0000

When you take an item with you on a camping trip and it fails, you are not normally in a position to replace it immediately, thus you have the choice of fixing it there and then, or doing without it. When his LED camping lantern failed, [Mark Smith] was in the lucky position of camping at a friend’s compound equipped with all the tools, so of course he set about fixing it. What he found shocked him metaphorically, but anyone who handles it while it is charging can expect the more literal variation.

The lamp was an LED lantern with …read more

Innovating A Backyard Solar Battery SystemSolar Powered Battery Systemthehacksmith

Wed, 19 Jul 2017 23:00:00 +0000

Ever on the lookout for creative applications for tech, [Andres Leon] built a solar powered battery system to keep his Christmas lights shining. It worked, but — pushing for innovation — it is now capable of so much more.

The shorthand of this system is two, 100 amp-hour, deep-cycle AGM batteries charged by four, 100 W solar panels mounted on an adjustable angle wood frame. Once back at the drawing board, however, [Leon] wanted to be able track real-time statistics of power collected, stored and discharged, and the ability to control it remotely. So, he introduced a Raspberry Pi running …read more

DEF CON Badgelife: The ESP Rules AllDEFCONBAdgebrianbenchoff

Wed, 19 Jul 2017 20:00:00 +0000

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

Hackaday Prize Entry: BeagleLogicBeaglelogicbrianbenchoff

Wed, 19 Jul 2017 18:30:53 +0000

A few years ago, [Kumar] created the BeagleLogic, a 14-channel, 100 MSPS logic analyzer for the BeagleBone as an entry for the Hackaday Prize. This is a fantastic tool that takes advantage of the PRUs in the BeagleBone to give anyone with a BeagleBone a very capable logic analyzer for not much cash.

This year, [Kumar] is back at it again. He’s improving the BeagleLogic with a BeagleBone on a chip. This is the BeagleLogic Standalone, a 16-channel logic analyzer at 100 MSPS using a single chip.

Like the BeagleLogic from a few years ago, [Kumar] is relying on those …read more
