A small engineering company in Germany called [Nerdindustries] decided to throw a party, and in doing so, wanted to squash some rumors that nerds only eat pizza and take out. We’d say they successfully one-uped their friends while proving they too can make gourmet food. The gathering included a massive sous vide cooker out of an old 240L aquarium. Be warned, their website presentation is rather annoying but worth it.
They got the aquarium off eBay for $40, and started the project by resealing the aquarium with some silicone. Water adding some aluminium extrusion they mounted six immersion heaters. Three to heat it to temperature, and another three running off a PID control loop with waterproof temperature sensors to maintain it within a degree or so. Of course that wouldn’t get you very far unless you completed the build by filling the aquarium with water.
To make it a bit fancier for the party, they also threw a projector above it to display some simple visuals in the water. For their big night, they cooked steaks at 60C for about an hour and a half, and then finished in a pan to sear before serving — they were a hit. There’s a video on the site, but we can’t embed it here, so you’ll have to go check it out!
Is Sous Vide still a hot topic with hackers? There was a flurry of activity a few years back (Sous Vadar obviously one of our favorites) but we haven’t seen nearly as many projects lately. Actually we recently saw a Sous Vide repurposed for brewing instead of cooking.
Do you like hacking? Do you like apple cider? Do you like ceiling fans? If you answered “yes” to any of those questions, then boy do we have the project for you! [Lou Wozniak] has an awesome tutorial for building an apple cider press using a ceiling fan motor and a handful of items available at your local hardware store.
The build is pretty simple in concept but complex in execution, and [Lou] does a fantastic job of covering every step in detail in his two project videos. The project has two main components: the grinder to decimate the apples and create a juicy, pulpy soup, and the press to extract the juice. The grinder is powered by the fan motor, while the press uses a screw-drive connected to a power drill, and then a ratchet to squeeze out every last drop.
Eager for more ceiling fan motor goodness? You’re in luck! Apparently [Lou] is a master of repurposing fan motors, and we featured a pottery wheel he made with one a while back.

Rectangles? Squares? Pie slices? Who says dessert has to come in that shape? Why not triangles, circles, or even hexagons? Master of all things woodworking [Matthias Wandel] decided to solve this problem, and delved into a bit of metal working.
Using a strip of 26 gauge stainless steel, [Matthias] threw together some wood clamps in order to bend the metal into funky looking blade. He then put slits into a nice wooden handle and assembled the whole thing with a very slight positive curve, allowing you to roll the knife as you cut your confectionery.
As you can see in the following video, it works pretty well — and always, it’s a pleasure to see this man work.

In a rather comical video, [Dom] and [Chris] of [ExplosiveDischarge] show us how to make a full English breakfast — without the use of a kitchen.
We’re talking eggs, bacon, ham, hash browns, and baked beans. Without the use of a single cooking element. Some of the methods were expected, like using a clothes iron as a portable grill — which is a great life hack by the way, especially when you’re at a hotel and just happen to have a package of bacon and nowhere to cook it… Or using a blow torch to flame-broil a perfect sausage — with the clever use of a drill-powered rotisserie using a variable power supply to adjust the speed!

[UpgradeTech] had a proof-of-concept itch they needed to scratch: making a playable record out of a tortilla using a laser cutter. The idea was spawned from the goofy “tortilla vinyl” YouTube video.
Uncooked flour tortillas were used. Corn tortillas were too lumpy while cooked tortillas shredded on the record player. To get the recording onto the tortilla, Audacity was used to modify a stereo WAV file. Using the RIAA equalization standard is a great choice here as it was originally adopted to prevent excess wear and tear on record grooves as the needle passed through. A Python script generated the files for the laser cutter, creating a text file with the sound data which was then processed into a vector PDF of the grooves. For each record it takes 30 minutes for the laser cutter to turn a simple flour tortilla into the musical variety.
Each tortilla can play 30-40 seconds of music at 45 or 78 RPM, but they start to warp once they dry out. Time to build a humidor around the record player! There is background noise that can make certain songs harder to hear, but there is unarguably audible music. There is plenty of room for optimizing the sound file, grooves, and cutting. We hope this project inspires others to make their own musical tortilla. Playing with your food has taken on a whole new meaning!

An engineering student at the University of Western Macedonia has just added another appliance to the ever-growing list of Internet enabled things. [Panagiotis] decided to modify an off-the-shelf bread maker to enable remote control via the Internet.
[Panagiotis] had to remove pretty much all of the original control circuitry for this device. The original controller was replaced with an Arduino Uno R3 and an Ethernet shield. The temperature sensor also needed to be replaced, since [Panagiotis] could not find any official documentation describing the specifications of the original. Luckily, the heating element and mixer motor were able to be re-used.
A few holes were drilled into the case to make room for the Ethernet connector as well as a USB connector. Two relays were used to allow the Arduino to switch the heating element and mixer motor on and off. The front panel of the bread maker came with a simple LCD screen and a few control buttons. Rather than let those go to waste, they were also wired into the Arduino.
The Arduino bread maker can be controlled via a web site that runs on a separate server. The website is coded with PHP and runs on Apache. It has a simple interface that allows the user to specify several settings including how much bread is being cooked as well as the desired darkness of the bread. The user can then schedule the bread maker to start. Bread Online also comes with an “offline” mode so that it can be used locally without the need for a computer or web browser. Be sure to check out the video demonstration below. Continue reading “Bread Online is a Bread Maker for the Internet of Things”
[Rhys Goodwin] has a wonderful Italian espresso machine, a Brasilia ‘Lady’. But the electronics in it are a bit outdated. So he decided to give the entire thing an overhaul, while keeping it as original as possible!
As far as espresso machines go, this model is pretty simple. It uses a 300mL brass boiler with a 3-position solenoid valve. The thermostat is one of those simple bimetallic button thermostats which sadly, aren’t even that accurate — you couldn’t build a simpler machine, there’s not even a microcontroller in it. [Rhys] had his work cut out for him.
Arduino. PID controller. LCD display. New custom machined components, including a polished aluminum face plate for the LCD! He didn’t skimp out on this restoration. He even designed his own custom PCB to house the Arduino and provide the outputs for his new electronics, impressive!
