Cookies, Baked The 3D Printer Way

June 2, 2026 by 20 Comments

Imagine for a moment that the Cookie Monster is going to visit, but all the cookie baking utensils in your house have been mislaid. The horror! Fortunately [Startup Chuck] is here with a video showing the process of baking cookies in a 3D printer, and as an extra treat he’s using entirely 3D printed utensils too.

The utensils are comprehensive array of all you’d need for serious cookie production, even going as far as to print a mixing bowl and beater for a KitchenAid mixer. There are scoops aplenty, and something we’re particularly impressed with, a spatula with a TPU blade. We’re guessing that FDM prints might not be the best for cooking because all manner of food could get caught in those layer lines and go off, but let’s face it, this is a bit of fun rather than a forever cooking project. We like the AI generated spork for its near-flatness, reminding us of our AI-generated breakfast. Finally he even prints a cookie baking sheet using nylon filament.

An enclosed 3D printer makes a surprisingly effective low-temperature oven, with the heated bed as the element. It works, and makes recognizable cookies, though they’re not browned. As entertaining as this experiment may be, we can’t recommend following his example — at the very least, moisture and food ingredients in your printer probably aren’t conducive to good future printing.

Know Your Food: Cheesemaking

June 1, 2026 by 80 Comments

There’s a thing that people who grew up on farms all share: a connection with food production that isn’t some mystical rose-tinted woo from a TV chef, but instead a practical general knowledge from being there on the ground. A glance at a crop in a field and you immediately recognise what it is, if it’s ploughing time you’ll know the soil type, and there’s always either too little, or too much rain. For a given foodstuff you’ll know far too much about where it came from, because if your dad wasn’t involved in its production, the chances are someone he knew was. You take this for granted, after all doesn’t everyone have this general knowledge? Seemingly not.

Hackaday is not a cooking channel, but I know we’re all interested here in how things are made. Shouldn’t that also extend to what we eat? It’s fashionable to follow a back-to-nature line that all commercial foodstuffs are somehow over-processed junk, but without the requisite knowledge you’re flying blind there. To know both how common foodstuffs should be made, as well as how they are made industrially, should be an essential for everyone.

Reverse Engineering A Rock Bottom NES Clone

June 1, 2026 by 4 Comments

The NES was Nintendo’s smash hit console of the 1980s, the international version of their Japanese Famicom system. It wasn’t a particularly complex device, so it was the subject of many clones back in the day. More recently, it has enjoyed a new life thanks to “NES on a chip” systems. It’s one of these that [Poking Technology] has, real rock bottom for the console built into a cheap phone case.

A Camera Viewfinder Makes A Great TV

May 31, 2026 by 2 Comments

When we think of CRT camera viewfinders, most of us probably imagine the tiny CRTs you’d find in a 1980s camcorder. They’re super cute and a load of fun to play with, but they’re very much a consumer device. Professional cameras of the type you’d find in a studio had their own viewfinders, which were a lot closer to a small TV. They’re about as high quality as it gets for a monochrome CRT, and [Evan Monsma] has done the conversion to a general-purpose monitor.

On one side, this is a very straightforward hack, simply a case of tracing wires to identify the power and video pins. Given a tool battery, the monitor fires up and gives a super-sharp picture. What we like about this is the wooden base he’s made for the thing, at the same time rough-and-ready, and professional-looking from the outside. It has a routed space for the cables, and once mounted flush with the monitor base and given a bit of wood stain, it looks almost as though it was manufactured that way.

It’s likely most of us won’t find a broadcast viewfinder in the trash, instead settling at best for a little Chinese portable TV. But it’s still interesting to see these unusual devices. Perhaps it might make a good cyberdeck.

Modern Graphics Via DisplayLink For Your ISA-Era PC

May 31, 2026 by 13 Comments

The monitors used on older computers are now becoming difficult to find, as we doubt anything for MDA, CGA, Hercules, or EGA has been manufactured in decades. Even VGA, though there are plenty of surplus flat panels to be found, is not as ubiquitous as it once was. Where does that leave the retrocomputing enthusiast with an ISA PC and no screen? Perhaps [Ian Hanschen] has the answer with the PicoGraph, an ISA-to-USB-to-Displaylink adapter.

In hardware terms, it’s using a PicoMEM, a more general-purpose ISA card for emulating cards with a Pi Pico. The Pico hosts a USB DisplayLink adapter, which can connect to the screen of your choice. The software on the PicoMEM does the heavy lifting and provides MDA, Herc, EGA, and VGA support, as well as support for one of the 1990s Cirrus Logic SVGA chipsets. And yes, it appears to work with DOOM.

The practice of using 2020s microcontrollers to lend functionality to retrocomputers has revolutionised the art. We’ve seen many, with one of the more recent being a minimap add-on for an 8-bit Sinclair Spectrum.

The Uncooperative Mirror Will Not Help You

May 30, 2026 by 7 Comments

The value of a mirror is in its clarity. If the reflection is cast by [danicakostic17]’s Uncooperative Mirror though, you’ll find anything but. It’s described as a useless machine, because it appears as a tiled mirror. As you approach it though, the tiles shake around and make it very difficult to follow what’s in front of you. It’s an art piece and a prank all in one, and we like it.

Behind the mirror is a 3D printed frame and a set of small servos with what look like some belts to hitch them up. There’s an ultrasonic sensor and an Arduino Uno, that sets those servos going as soon as the ultrasonic sensor sees anything. We can see this thing would be fun at a party.

Everything you’ll need is on the Instructables page linked above should you be foolhardy enough to want your own, and there’s even a YouTube video which we’ve placed below.

It’s Another Pi Handheld. But It’s A Really Good One

May 30, 2026 by 28 Comments

Ever since the first Linux capable single-board computers came out, there have been projects turning them into handhelds. The Raspberry Pi Zero and in particular the Compute Modules are ideally suited to this. While there are more common projects that find their way into our feed we’ve certainly seen a few of them in our time, enough now that a new one has to be special to really catch our eye. Which brings us to the PiBrick from [Ahmad Amarullah], which sets the bar pretty high.

The device is a Compute Module 5 smartphone sized computer with a 3.92″ OLED touch display and the ubiquitous BlackBerry-derived keyboard. It’s drawn together with a PCB that holds all components and peripherals, and this and the 5000 mAH battery fit in a 3D printed shell that gives it the form factor of a chunky smartphone. You can see it at the link above, and also find it in a GitHub repository.

Handheld computers always represent something of a compromise as they can only ever offer relatively small screens and keyboards. But they live or die on their versatility and robustness, both of which this one has in spades. We like it, a lot.

Thanks [Nick] for the tip.
