Mindstorms Forkliftbots Gonna Take Your Jobforkliftbots_mainnerdyjb

Fri, 17 Nov 2017 21:01:42 +0000

With every advance in robotics, we get closer to being able to order stuff from Amazon and have no human being participate in its delivery. Key step in this dream: warehouse robots, smart forklifts able to control and inventory and entire warehouse full of pallets, without the meat community getting involved. [Thomas Risager] designed just such a system as part of his Masters Thesis in Software Engineering. It consists of five LEGO Mindstorms robots working in concert (video embedded below), linked via WiFi to a central laptop. Mindstorms’ native OS doesn’t support WiFi (!!!) so he reflashed the EV3’s ARM9 …read more

Hacking the IKEA Trådfri Light Bulbtradfrinerdyjb

Fri, 17 Nov 2017 21:00:25 +0000

[BasilFX] wanted to shoehorn custom firmware onto his IKEA Trådfri light bulb. The product consists of a GU10-size light bulb with a LED driver as well as IKEA’s custom ZigBee module controlling it all. A diffuser, enclosure shell, and Edison-screw base give the whole thing the same form factor as a standard A-series bulb. The Trådfri module, which ties together IKEA’s home automation products, consists of an ARM Cortex M4 MCU with integrated 2.4Ghz radio and 256 Kb of flash — not bad for 7 euros!

Coincidentally, [BasilFX] had just contributed EFM32 support to RIOT-OS (“the friendly OS for IoT”) …read more

Modernizing a 170 year old Antique Grandfather Clockgrandfather_clock_02anool

Fri, 17 Nov 2017 19:30:00 +0000

Frankly, we let out a yelp of despair when we read this in the tip line “Antique Grandfather clock with Arduino insides“! But before you too roll your eyes, groan, or post snark, do check out [David Henshaw]’s amazing blog post on how he spent almost eight months working on the conversion.

Before you jump to any conclusions about his credentials, we must point out that [David] is an ace hacker who has been building electronic clocks for a long time. In this project, he takes the antique grandfather clock from 1847, and puts inside it a new movement built …read more

What Actually Happens At A Hardware Hacking ConBadgehackingheaderbrianbenchoff

Fri, 17 Nov 2017 18:01:47 +0000

The Hackaday Superconference was last weekend, and it was the greatest hardware con on the planet. What can you build out of a conference badge? If you answered “a resin-based 3D printer” you would have won a prize. If you decided to put your badge in a conference water bottle and make a stun gun you’d receive adoration of all in attendance. Yeah, it got that crazy.

At other tech conferences, you’ll find gaggles of nerds sitting around a table with MacBooks and Thinkpads. The Superconference is different. Here, you’ll find soldering irons, tackle boxes filled with components, and loose …read more

DIY Capacitive Rotational Encoder on the Cheap with FR4Capacitive Rotary Encoder Featureddp2cnk

Fri, 17 Nov 2017 16:30:00 +0000

Rotary encoders are critical to many applications, even at the hobbyist level. While considering his own rotary encoding needs for upcoming projects, it occurred to [Jan Mrázek] to try making his own DIY capacitive rotary encoder. If successful, such an encoder could be cheap and very fast; it could also in part be made directly on a PCB.

The encoder design [Jan] settled on was to make a simple adjustable plate capacitor using PCB elements with transparent tape as the dielectric material. This was used as the timing element for a 555 timer in astable mode. A 555 in this …read more

Goodbye, TechShopTechShopHeaderdanielharrigan

Fri, 17 Nov 2017 15:01:14 +0000

The CEO of TechShop, [Dan Woods], has hit the legal E-stop and declared Chapter-7 bankruptcy for the business. All ten US locations were shuttered on Wednesday with absolutely no advance warning. You can read the full statement from [Dan] here.

We are deeply saddened to hear of TechShop’s closing, and while it wasn’t implausible that this might happen someday, the abrupt shuttering must come as a painful shock to many for whom TechShop was an important part of their personal and professional lives. We owe a lot to the work and effort they put forth; they led the way as …read more

Is Intel’s Management Engine Broken yet?800kripthor

Fri, 17 Nov 2017 12:00:00 +0000

Our own [Brian Benchoff] asked this same question just six months ago in a similar headline. At that time, the answer was no. Or kind of no. Some exploits existed but with some preconditions that limited the impact of the bugs found in Intel Management Engine (IME). But 2017 is an unforgiving year for the blue teams, as lot of serious bugs have been found throughout the year in virtually every fields of computing. Researchers from Positive Technologies report that they found a flaw that allows them to execute unsigned code on computers running the IME. The cherry on top …read more
