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!

Why do light bulbs, furnaces, outlets and even automated blinds get all the home automation love? Won’t somebody think of the kettle!? How are we suppose to ensure tea-time is always a button click away? Tired of his lack of options for remotely controlling his kettle, [FatCookies] decided to make his own WiFi enabled kettle.
He started by ripping up an old power supply enclosure he had lying around, and it happened to be just big enough for a Raspberry Pi. He then added a 2-way relay board designed for handling mains voltage at a high amperage — quite necessary for something that draws as much as a heating element.
From there it was just a matter of wiring the relay board to the GPIO on the Pi, and to the kettle itself. For safety reasons, he’s powered the kettle and the Pi separately — and don’t worry, he left the safety switch in the kettle intact.
And while we have to admit, it’s not the most aesthetically pleasing hack, it certainly does the trick — and didn’t cost [FatCookies] much at all.
But if you’re more of a coffee kind of person — you could also replicate this hack with a coffee maker instead.
If you like to cook or bake, you probably don’t measure everything out in little bowls and ramekins before you start. Well,unless you also happen to like doing dishes. Even so, there are a lot of measuring spoons and -cups that end up getting dirty in the process. But what if you had a measuring machine to dole out spices and low-viscosity liquids in specific quantities for you?
[enddev]’s creation is based around an Arduino Mega, and the interface is three buttons and an LCD. The user selects between liquid and powder, followed by the desired measurement. If liquid is chosen, the peristaltic pump is engaged to deliver the specified amount through silicone tubing. The current powder setup uses a kitchen scale, which the designers found to be inaccurate for small amounts. They believe that a volume auger and stepper motor would be ideal.
The team mentions that the powder delivery system is better suited for flakier substances since it’s basically agitated out of the container. This makes us think this would be great for feeding fish. If you take this admirably-written Instructable and use it to feed your fish or something, let us know. Their code is on the gits.

If you’re creative, you can make your passion projects count for college credit. Somehow [InfinityTable] managed to use this infinity bartender build called BarT as a senior design project.
There’s a lot going on here, starting with the cabinet which is 30″x30″ and has some custom mirrored glass necessary because of a square cut-out in the middle of the front pane. The two mirrors face each other, with a strip of LEDs in between which accounts for the “infinity” part of the build. This is popular but usually it’s usually just the mirror and lights. In this case that special cut-out is a cubby for a glass. Place it in there and the rest of the build will mix you up a tasty beverage.
There is a second chamber in the enclosure behind the rear mirror. This houses the components that mix up the drinks. Raw materials are dispensed from 1.25L plastic bottles. The extra special part of the build is that since it is a senior project, all the driving circuitry uses roll-your-own boards.
