Building A Water Cooled Raspberry Pi 4 Cluster

I built a water cooled Raspberry Pi 4 a couple of weeks ago. This was obviously crazy overkill for a single Raspberry Pi, but it isn’t actually why I bought the water cooling kit, I bought it along with 7 other Raspberry Pis so that I could try building my own water cooled Pi Cluster. I’ve really enjoyed the past few weekends putting it together. So, here’s a video of my Pi 4 cluster build, I hope you enjoy it!

3D Printed Pi Arcade is an Emulation Horn of Plenty

Let’s be honest, building a home arcade cabinet isn’t exactly the challenge it once was. There’s plenty of kits out there that do all the hard work for you, and they even sell some pretty passable turn-key units at Walmart now. If you want to put a traditional arcade cabinet in your home, it’s not hard to get one.

Which is why this wild build by [Rafael Rubio] is so interesting. The entirely 3D printed enclosure looks like some kind of art piece from the 1970s, and is a perfect example of the kind of unconventional designs made possible by low-cost additive manufacturing. Building something like this out of wood or metal would be nightmare, especially for the novice; but with even a relatively meager desktop 3D printer you’re only a few clicks away from running off your own copy.

Tiny 3D-Printed DEC VT-102 Hides a Fully-Functional, ESP32-Powered PDP-11 Minicomputer

A tiny screen and a 3D-printed chassis brings some of Digital’s fondest-remembered hardware up to date — and down in scale.

Jeroen “Sprite_tm” Domburg has been working on a build with a difference: It’s an ultra-compact replica of a Digital DEC VT-102 terminal, emulating a PDP-11 running 2.11BSD — all on the top of an Espressif ESP32 microcontroller.

“The thing that attracted me to the PDP11 is that the PDP line in general always has been a family of ‘hackers’ machines,'” Sprite_tm explains. “Its members were cheap enough to allow people to do fun stuff on, and for instance the first computer game, SpaceWar!, was written on a PDP1. It wouldn’t be the last game written on a PDP machine, though: Apart from the aforementioned arcade games, all the way in Russia on a cloned PDP-11, Russian software engineer Alexey Pajitnov wrote a certain title called ‘Tetris,’ which later was spread all over the world.”

The Legend of Zelda: Ocarina of Time Leak Reveals Cut Content and Never-Before-Seen Assets

A massive Legend of Zelda: Ocarina of Time leak has surfaced online revealing cut content and never-before-seen assets of the 1990’s Nintendo 64 game. Earlier today, a big upcoming Nintendo Switch game leaked, courtesy of GameFly. This new leak comes the way of a prototype Nintendo 64 cartridge of F-Zero X that contains data from an early build of Zelda 64 which is somehow only now seeing the light of day.

Wii Classic Mini Console Could Be Hitting Your Living Room In 2023

If hands-on, energetic gaming is your bag, then the arrival of the Wii Classic Mini Console will be something that you’ll already be eagerly anticipating.

The Wii was undoubtedly one of the most innovative consoles of our generation; that’s something that you can’t deny, whether you’re a Nintendo fan or not.

Taking a simple action that most people use every day like pointing a remote at a T.V and turning it into a gaming device was a complete gamechanger. What’s more, it was also the first step towards creating the joy-cons for the Nintendo Switch (a combination of the Wii’s ingenious playing style and the controller/screen hybrid from the not-so-portable Wii-U).

Making your own Segway, the Arduino way

After obtaining motors from a broken wheelchair, this father-son duo went to work turning them into a new “Segway.”

The DIY transporter is controlled by an Arduino Uno, along with a pair of motor drivers that handle the device’s high current needs. An MPU-6050 allows it to react as the rider leans forward and backwards, moving with the help of a PID loop. Steering is accomplished via a potentiometer, linked to a bent-pipe control stick using a bottle cap and glue.

Hands-On with the RP2040 and Pico, the First In-House Silicon and Microcontroller From Raspberry Pi

The RP2040, Raspberry Pi’s first in-house silicon, debuts on the Raspberry Pi Pico, its first microcontroller board — and it’s just $4.

The launch of the original Raspberry Pi in 2012 was the dawn of a new era of low-cost, easy-access single-board computers (SBCs). In the years since the Raspberry Pi family has grown both upwards, now on its fourth full generation, and outwards with a range of devices from the ultra-low-cost Raspberry Pi Zero family to the consumer-ready all-in-one Raspberry Pi 400.
