What is electricity? This question is impossible to answer because the word " Electricity " has several contradictory meanings. These different meanings are incompatible, and the contradictions confuse everyone. If you don't understand electricity, you're not alone. Even teachers, engineers, and scientists have a hard…
In his own words, James Dyson reveals the Dyson electric vehicle.
This article is part of a series: This article How I moved my setup from a Mac to a Linux laptop Fed up with the Mac, I spent six months with a Linux laptop. The grass is not greener on the other side The M1 Macbook Air, one year
After seeing it in action at FOSDEM (from afar, as the crowd was too large), I decided to buy a Pinebook Pro for personal use. From the beginning, the intention was to use it for pkgsrc development, with NetBSD as the main OS. It was finally delivered on Thursday, one day earlier than promised, so I thought I would…
For a long time when I’ve wanted to test the latency of computers and UIs I’ve used the Is It Snappy app with my iPhone’s high speed camera to count frames between when I press a key and when the screen changes. However the problem with that is it takes a while to find the exact frames you want, which is annoying when…
As I was debugging a wireless mouse based on a 2.4 GHz proprietary protocol, I wanted to detect the transmitted signals. Note that I purposefully wrote “detect”: It was sufficient to see how often the transmission occurred (and if at all) and whether the link was unidirectional – i.e., only the mouse transmits and the…
Floating-point numbers are very useful for scientific programming, but early microprocessors only supported integers directly. 1 Although...
A new 8GB RAM variant of Raspberry Pi 4 is available today, priced at just $75. Visit your favourite Raspberry Pi Approved Reseller to get yours.
Taking a second look at the newly introduced mask registers, this time with the benefit of a SKX die shot from Fritzchens Fritz.
Light-weight, cheap and ultra-thin, perovskite solar cells have promised to shake-up renewable energy for some time. Research by Professor Anita Ho-Baillie from the University of Sydney means they are ready to take the next steps towards commercialisation.
A few months ago, after my System76 Galago Pro had its second experience with a dead/swelling batery, I decided that it was time to replace it. On February 15th, I ordered a Dell Latitude 7390.
FPGAs can be seen as a bridge between the domains of hardware and software as their hardware operation can be reprogrammed using code, giving developers unprecedented flexibility. In advanced products that Antmicro helps its customers build, this flexibility to process parallel data often needs to be complemented with…
TSMC showed the power of modularization, and now they are core to the U.S. national security strategy.

Intel introduced the 8087 chip in 1980 to improve floating-point performance on the 8086 and 8088 processors, and it was used with the ori...
Discover how to create a DIY particle detector using silicon photodiodes, the same technology employed in professional particle and nuclear physics experiments.
With the PinePhone and Pinebook Pro production well under way and shipping in just a few days time, we’ll now be turning our attention to the other projects we have in the pipeline. There is a fair bit of material to cover this month - the main piece of news, however, is that we’ll be taking pre-orders for the PineTab…
Remember the old video game Space Invaders? Some of its sound effects were provided by a chip called the 76477 Complex Sound Generation ch...

How I found a vintage Apple IIe computer on the sidewalk and brought it back to life
Blog about vintage computers and homebrewing computers.
After anki trashed my history, uploaded the trashed history to the sync server, and then repeatedly re-synced the trashed history every time I tried to restore from backup, I wrote my own spaced repetition app. It reads input from a markdown file, asks questions in the terminal and stores state in a json file. I wrote…
I saw an ad for a tiny chip 1 that provides 5 volts 2 of isolated power: You feed 5 volts in one side, and get 5 volts out the other si...
Iran’s new military satellite, NOUR 01, most interesting fact may not be that it resembles a college engineering experiment but rather that it may have a connection to a Mexican military payl…
