People Are Using Old Laptop Batteries to Build Their Own Versions of Tesla’s Powerwall

https://futurism.com/people-are-using-old-laptop-batteries-to-build-their-own-versions-of-teslas-powerwall/ Tesla’s Powerwall was intended to provide a convenient way for homeowners to store electricity for future use, such as when the power goes out. But with a $5,500 price tag, they haven’t been affordable for many consumers.  Some who had been interested in the tech, however, decided to try to make their own: constructed their own powerwalls by utilizing

Is your encrypted USB drive secure?

https://www.kaspersky.com/blog/encrypted-usb-drives-audit/17948/?utm_source=kasperskysocialchannel.com&utm_medium=Kaspersky+Lab+%28Employees%2C+USA%29&utm_campaign=kasperskysocialchannel.com How can you be sure the “secure” USB drive you’re using is really secure and the data you store on it can’t be extracted? That’s exactly the question Google’s security researchers Ellie Bursztein, Jean-Michel Picod, and Rémi Audebert addressed in their talk, “Attacking encrypted USB keys the hard(ware) way,” at the recent Black Hat

Arduino emulating an 8086 PC (a work in progress, but it’s working) – arduino

https://www.reddit.com/r/arduino/comments/6sdtxr/arduino_emulating_an_8086_pc_a_work_in_progress/ This looks amazing work in progress:  code to emulate the basics of a typical 1980′s PC (video card, disk controller, input, 8253 timer chip, 8259 interrupt controller, etc), wired up 1 MB of SRAM on the breadboard, and added a 2.8″ 320×240 LCD display. I embedded a public domain XT BIOS in the PROGMEM.

Assembly summer 2017 wild demos

https://m.youtube.com/playlist?list=PLJO4AtxKJiFMa-xhNLNpp-URxQH-7Ka6Q This YouTube playlist shows videos of interesting hardware plus software hacks. They can play computer demo multimedia with old game consoles, Arduino+LED sign, LEGOs and audio mixer… Many cool hacks I would say!  Assembly Summer 2017 event is still going on, more videos at AssemblyTV at YouTube and Assembly Summer 2017 pages.

Probing Ethernet cable with an oscilloscope

This article talks about measuring 10 Mbit/s (10Base-T) and 100 Mbit/s (100Base-TX) twisted pair Ethernet signals. Those standards use two wire pairs for the communications and use differential signaling. Differential signaling is a method for electrically transmitting information using two complementary signals. The technique sends the same electrical signal as a differential pair of signals,

Reverse Engineering Hardware of Embedded Devices

http://blog.sec-consult.com/2017/07/reverse-engineering-hardware.html?m=1 Nowadays, we are living in a world dominated by embedded systems. Everyone can be spied on through various channels. Routers, IP-cameras, phones, and other embedded devices are affected by security vulnerabilities and are therefore easily hack-able.  This article covers some basic hardware reverse engineering techniques on PCB-level, which are applicable to any electronic embedded

GarrettCom Converter Repair

http://www.epanorama.net/newepa/2015/01/14/garrettcom-converter-teardown/ I did more than two years ago tear-down of this 100 Mbit/s copper to fiber Ethernet media converter (link above). Now I decided to try to fix it. It turned out that originan PSU did not put out right 3.3V voltage, but considetably less. The digital electronics worked out nicely when fed with 3.3V

HoloKit is like Google Cardboard for augmented reality | TechCrunch

Or is it? HoloKitis an extremely clever DIY solution for a quick and dirty augmented reality experience with
