Why Raspberry Pi isn't vulnerable to Spectre or Meltdown - Raspberry Pi
https://www.raspberrypi.org/blog/why-raspberry-pi-isnt-vulnerable-to-spectre-or-meltdown/, posted 2018 by peter in hardware security
Spectre and Meltdown are side-channel attacks which deduce the contents of a memory location which should not normally be accessible by using timing to observe whether another location is present in the cache.
A great article that explains the widely debated security vulnerabilities in some CPUs.

Intel x86s hide another CPU that can take over your machine (you can't audit it) / Boing Boing
https://boingboing.net/2016/06/15/intel-x86-processors-ship-with.html, posted 2016 by peter in crapification hardware privacy security toread
When you purchase your system with a mainboard and Intel x86 CPU, you are also buying this hardware add-on: an extra computer that controls the main CPU. This extra computer runs completely out-of-band with the main x86 CPU meaning that it can function totally independently even when your main CPU is in a low power state like S3 (suspend).

Is there an Internet-of-Things vigilante out there? | Symantec Connect

Wifatch’s code does not ship any payloads used for malicious activities, such as carrying out DDoS attacks, in fact all the hardcoded routines seem to have been implemented in order to harden compromised devices. We’ve been monitoring Wifatch’s peer-to-peer network for a number of months and have yet to observe any malicious actions being carried out through it.

On the Origin of Circuits
www.damninteresting.com/on-the-origin-of-circuits/, posted 2015 by peter in ai evolution hardware science toread
The informatics researcher began his experiment by selecting a straightforward task for the chip to complete: he decided that it must reliably differentiate between two particular audio tones. A traditional sound processor with its hundreds of thousands of pre-programmed logic blocks would have no trouble filling such a request, but Thompson wanted to ensure that his hardware evolved a novel solution. To that end, he employed a chip only ten cells wide and ten cells across— a mere 100 logic gates. He also strayed from convention by omitting the system clock, thereby stripping the chip of its ability to synchronize its digital resources in the traditional way.

LedBorg - An ultra bright RGB LED add on board for your Raspberry Pi | PiBorg
https://www.piborg.org/ledborg/specs, posted 2015 by peter in hardware raspberrypi visualization
The LedBorg provides a tri-colour LED controllable from the Raspberry Pis GPIO header. Using simple on / off logic it can provide a total of seven colours as well as off. Using software based pulse width modulation (PWM) it is capable of many more colours, around a million in fact.

This Vertical Take-Off Drone is Like Your Own Mini Harrier Jet
makezine.com/2015/02/20/krossblade-skyprowler-vtol-drone/, posted 2015 by peter in aviation hardware
Quadcopters are great at hovering, but don’t have long range. Fixed-wing aircraft can travel long distances quickly, but don’t like to stay in one place above the ground.
Krossblade’s SkyProwler solves both of those problems. The hybrid aircraft is a remote controlled quadcopter with wings, or a plane with six rotors, capable of vertical takeoff and landing (VTOL).

The USB Weather Data Receiver USB-WDE1 wirelessly receives data from various weather sensors of ELV at 868 MHz. The receiver is connected to a USB port on the computer, so no additional power supply is required. The data is transmitted via a simple serial ASCII protocol, which is well documented by ELV. The RasberryPi running Raspbian is used for the data acquisition allowing very little power consumption while being completely flexible.
Our USB Typewriter circuitry can transform your old manual typewriter into a retro-futuristic marvel. Use a gorgeous vintage typewriter as the computer keyboard for your Mac or PC, or type with ink-on-paper while electronically recording your keystrokes! The USB Typewriter also makes an outstanding keyboard dock for your iPad or tablet PC.
