Introduction   The CA6526 is the first insulation tester to be added to my portfolio for my grand scheme of testing it against the Keysight  U1461A that has failed me and the Megger  MIT420/2 that I road tested for element14 last year   Keysight U1461A failure   Megger MIT420 road test   As a comparison, the CA6526 falls in-between the Keysight and the Megger units. It offers similar functionality as the Megger unit and is primarily an insulation tester and n ...
Last year, new research resulted in a tiny chip specially designed to fit in and power bee-sized drones. This year, the size of the chip was reduced even more along with its consumption of power. Here Navion placed next to a quarter and a small drone for perspective. (Image via MIT)   MIT’s Department of Electrical Engineering and Computer Science and the Department of Aeronautics and Astronautics joined forces to create a micro-chip that will help run efficiently the mini size drone ...
This is just a utilitarian blog post on how to integrate the BOOST library in your project, in support of SCPI on a Linux Board - Part 3: TCP/IP Socket C++ programming. Targeted to cross-compile people that build the project on Windows and execute the code on Linux. Because this is an instructions post only, I don't make an effort to make it look nice.     Build the BOOST libraries That's easiest done on the Pi (or other linux machine). you can later delete the package if you decide ...
I'm building a SCPI electronics lab instrument for Linux. This post is an object oriented one again: testing if I can create a stream-like socket server in C++. TL;DR yes If you are interested in object oriented design, you may want to stay and read.   This blog post is a preparation for the SCPI programmable instrument I'm building for the Raspberry Pi and the PiFace Digital hat. The SCPI parser will be in plain C: SCPI on a Linux Board - Part 1: Proof of Concept. The instrument it ...
I'm building a SCPI electronics lab instrument for Linux. This post is an object oriented one: porting the PiFace Digital API to C++. If you aren't interested in object oriented design, you may want to walk away from this blog.     API and Abstraction  I've used exactly the same level of abstraction as the PiFace official procedural API. The OO API you talk to is the one that knows the PiFace Digital hat inputs and outputs. That API depends on a separate more low level OO ...
The technology allows researchers to study patients with Parkinson's disease and allows them to monitor mobility. Artificial intelligence demonstrates the movement of a person behind a wall by using a stick figure as a representative of their body. (Image via MIT) Researchers have made it possible to see a person in motion on the opposite side of a wall through the use of radio signals and artificial intelligence. This technology isn't entirely new in today's world. It has been used before on ...
A new phone protection case turns the smartphone into a weapon and explosive detector. Image of the SWORD app scanning a guy. (Image via Royal Holdings)   Every owner of a smartphone knows that it is wise to protect the device. For that purpose, companies rival with all kind of cases: from the minimalist ones to the multi-functional ones that offer more than just protection for the phone. One of those multi-function protection cases is redefining how security is ensured. With that phone ca ...
I'm building a SCPI device for Linux. I have the basis working over TCP/IP. This morning I received a PiFace Digital 2 from element14 (thank you!) This board, with digital inputs, outputs, relays and LEDs can be a nice LAB automation utility.   In this post I check if I can control the PiFace Digital 2 via C. TL;DR yes   In this series, I'm focusing on the specifics for TCP/IP communication with a SCPI service. In the previous posts I made socket server that listens for SCPI ...
MIT thinks they have a way to stop hackers, but can anything truly be unhackable? (Photo via Wiley Systems)   Whether you love them or hate them, smart devices are taking over. It feels like everything we own and do is connected to the internet: our phones, TVs, and even our cars. And while it can make our lives easier, it opens us up to new dangers, like hacking. All these devices can be hacked and have their data perched, overwritten, can jam signals, and cause havoc in general. Companie ...
Many tech companies come together to devise a tool that will allow blind people to have a more normal life and feel more included in social dynamics. USB-IF HID plugged into a phone. (Image via Microsoft)   In the United States, it is a crime to discriminate against anyone when it comes to basic necessities like holding a job. Actually, discrimination against anyone is not recommended, but it is probably harder to defend oneself against it when carrying a disability. To prevent discriminat ...
Have you ever wondered if it's possible to convert your cassette tape players into an mp3 music player? Thanks to TapelessDeckPlayer, the idea is now possible and seems both inviting and enticing for music enthusiasts who are still in possession of their cassettes. After all, who'd be crazy enough to throw them out - especially in this modern and music digital age? The TapLess Deck Player features some pretty nifty add-ons that you would be surprised to know exists on this deck player. It has w ...
How often do people complain about not being able to stay connected or together at big events, or in areas that don’t allow for internet connectivity? Well, now, for all those issues, there is a solution. The Lynq device, one of the many colors available. (Image via Lynq)   I don’t like to talk about a finished product at this level, usually. But this one is so cool. It’s a “why didn’t I make this” scenario. This is a real life tracker like Ripley used i ...
