This is an IBM 1401 scaled model I am working on, part of a diorama. It is a scratch build made of polystyrene mostly.
I make everything by hand, no 3D printing involved.
The IBM 1401 is a computer from 1959, considered to be the first successful mass produced computer. I have been working on this miniature diorama since December last year, to celebrate its 60th anniversary.

I2C, or Inter-integrated Circuit, is a communications protocol common in microcontroller-based systems, particularly for interfacing with sensors, memory devices and liquid crystal displays. Similar to SPI, it’s a synchronous protocol because it uses a clock line. The I2C protocol, however, uses less pins and is a much more robust standard.
New ATmega644 and ATmega1284-based boards boast the power — though not pins — of a Mega in a footprint only slightly larger than the Nano.
Catalonian maker Thierry Guennou’s Pandauino has launched what he claims is the smallest ever breadboard-compatible development boards to feature the Microchip ATmega644 or ATmega1284 microcontrollers.
“644 Narrow and 1284 Narrow are the simplest and perfect upgrade option for all your small footprint Arduino projects,” Guennou claims of his designs, which use microcontrollers more commonly associated with large boards like the Arduino Mega. “The Narrow board gives you two to eight times more flash and RAM resources as compared to a Uno/Nano, plus total compatibility.”
This is a quick peek at the hardware portion of the DIY garden automation system I’ve been slowly building over the past year or so. Currently, the system is managing climate control, doing pH and nutrient dosing, fertigation schedule, light cycle, and has flood detection capability. It’s a work in progress and I’ll be sharing more about it as I go.
FFT spectrum analyzer is a test equipment that uses Fourier analysis and digital signal processing techniques to provide spectrum analysis.
While electronics and water don’t generally mix, researchers at Ochanomizu University in Japan have come up with an ephemeral display method that uses floating clusters of bubbles to show messages on a liquid surface.
The device, known as UTAKATA, utilizes a line of seven electrodes under Arduino Uno control that activate to form hydrogen bubbles via electrolysis. When arranged properly, these bubbles can be made to produce letters and words, which as shown in the video below, dissipate as they flow downstream in the container.
Here’s the thing about lightsabers that isn’t acknowledged enough: They’re just as dangerous for their users as they are for enemies facing off against them. Which isn’t a big deal considering the elegant weapons for a more civilized age are fictional, but in real life, this fact becomes frightening relevant. Check out the Hacksmith’s “world’s first protosaber” build for proof of that assessment, as well as an understanding of why a true energy sword is not only nearly impossible to build, but also unwise to wield.
In this video we take a look at the all-new Pi-Top 4, A Raspberry Pi4 powered Educational computer that combines digital making, coding, and practical projects in an easy to use format. With a 4Gb Raspberry Pi 4 Built-in battery, Fan, and OLED Mini Display this little kit is actually really amazing but it does come at a hefty price of $299 USD!
I have thought of creating a sensory system to be put on a self-driving mini toy car. This mini toy car is controlled by a Raspberry Pi 3 on which I have installed the ROS (Robot Operating System).
The internet is obsessed with two songs and two songs only. But for different reasons. The first is Smash Mouth’s “All Star.” It’s a bad song that garners a lot of ironic admiration. It’s silly and it lends itself perfectly to silly covers. The world wide web’s other musical obsession though legitimately rules—Toto’s “Africa.” Whether it’s being played with sweet potatoes or being sung via a litany of cartoon impressions, it always sounds great. There’s just something inherently electric about it, which is why it’s also amazing when played entirely by Tesla coils.
