How complicated can a toaster be? You can get a cheap one for way under $10 that is little more than a hot wire. However, there are a few little complications. First, consumer products need to be safe — lawsuits are expensive. Second, there has to be some mechanism to hold the toast down until it is done. If you can buy one for $10 you can bet it isn’t some super toast processor running Linux in there.
[Technology Connections] tore one down for you so you don’t have to. The circuitry is simple, and who knew there was a dedicated IC for toaster control? However, the real engineering is in the lowly little handle you pull down to start the toasting.

There are few scenes in life more moving than the moment the solder paste melts as the component slides smoothly into place. We’re willing to bet the only reason you don’t have a reflow oven is the cost. Why wouldn’t you want one? Fortunately, the vastly cheaper DIY route has become a whole lot easier since the birth of the Reflowduino – an open source controller for reflow ovens.
This Hackaday Prize entry by [Timothy Woo] provides a super quick way to create your own reflow setup, using any cheap means of heating you have lying around. [Tim] uses a toaster oven he paid $21 for, but anything with a suitable thermal mass will do. The hardware of the Reflowduino is all open source and has been very well documented – both on the main hackaday.io page and over on the project’s GitHub.
The board itself is built around the ATMega32u4 and sports an integrated MAX31855 thermocouple interface (for the all-important PID control), LiPo battery charging, a buzzer for alerting you when input is needed, and Bluetooth. Why Bluetooth? An Android app has been developed for easy control of the Reflowduino, and will even graph the temperature profile.
When it comes to controlling the toaster oven/miscellaneous heat source, a “sidekick” board is available, with a solid state relay hooked up to a mains plug. This makes it a breeze to setup any mains appliance for Arduino control.
We actually covered the Reflowduino last year, but since then [Tim] has also created the Reflowduino32 – a backpack for the DOIT ESP32 dev board. There’s also an Indiegogo campaign now, and some new software as well.
If a toaster oven still doesn’t feel hacky enough for you, we’ve got reflowing with hair straighteners, and even car headlights.
The original Nintendo Entertainment System is affectionately called “the toaster” due to the way the cartridge is inserted. [MrBananaHump] decided to take things a bit literally and installed a NES inside an actual toaster. This isn’t [MrBananaHump’s] design, the Nintoaster comes to us from [vomitsaw], who also built the SuperNintoaster. Since [vomitsaw] was kind enough to document his original build, [MrBananaHump] was able to build upon it.
The target toaster for this build was a plastic Sunbeam model found at a thrift store for $5. [MrBananaHump] gutted the toaster and cleaned out years of toast crumbs. The Nintendo mainboard would fit perfectly inside a toaster, except for two things – the RF Modulator and the expansion port. The expansion port was never used in the US version of the NES so it can be desoldered and removed. The RF also needs to be desoldered and relocated.
By far the biggest job in this casemod is hand-wiring each of the 72 pins for the cartridge port. It’s a tedious job, and it probably won’t look pretty. Keep your wires short, and things will probably work thanks to the relatively low clock speed of the NES.
The cartridge goes in one toast slot. [MrBananaHump] mounted his controller ports, power and reset buttons in the second slot. A bit of expanded metal grid completes the slot. Sure, it’s not exactly pretty inside, but with the case on, this becomes a rather nice looking build.
We’ve seen numerous Nintendo casemods over the years, just one other example is this N64 in an N64 controller.
In the Red Dwarf TV series, Talkie Toaster wants to know if you want toast, and if not toast, then maybe a muffin or waffle, and it will pester you incessantly until you smash it with a 14lb lump hammer and throw it in a waste disposal. Now [slider2732] has actually gone and made one of the infernal machines!
He’s hidden a PIR sensor in the toaster handle to tell an Arduino Pro Mini when someone is unfortunate enough to be passing by. The Arduino then reads sound files from an SD card reader and plays them through a 3 watt amplifier out to a speaker. For that he uses the TMRpcm library available on github.
[slider2732] cleverly mounted the speaker to the side of the toaster along with some appropriately shaped bits and pieces, and some LEDs to make it appear and work much like the circular panel that lights up on the real Talkie Toaster. We dare you to watch the video after the break, unless you really are looking for toast. As a consolation, the video also walks through making it.

2014 was the year that the Internet of Things (IoT) reached the “Peak of Inflated Expectations” on the Gartner Hype Cycle. By 2015, it had only moved a tiny bit, towards the “Trough of Disillusionment”. We’re going to try to push it over the edge.
Depending on whom you ask, the IoT seems to mean that whatever the thing is, it’s got a tiny computer inside with an Internet connection and is sending or receiving data autonomously. Put a computer in your toaster and hook it up to the Internet! Your thermostat? Hook it up to the Internet!? Yoga mat? Internet! Mattress pad? To the Intertubes!
Snark aside, to get you through the phase of inflated expectations and on down into disillusionment, we’re going to use just one word: “security”. (Are you disillusioned yet? We’re personally bummed out anytime anyone says “security”. It’s a lot like saying “taxes” or “dentist’s appointment”, in that it means that we’re going to have to do something unpleasant but necessary. It’s a reality-laden buzzkill.)

Why toast your bread evenly when you can burn low-resolution images instead? Meet the Super Mega Mega Toaster, a University project created by [Scott van Haastrecht] for his Creative Technology course.
Now you may be thinking that this has been done before. And indeed, a bit of searching will lead you to a post about toasting Jesus. But that is a one-shot toaster hack which simply used a stencil to block heat to create a certain pattern. This is a mechanical overhaul for the toaster concept. It uses one row of six heating elements. Each is connected to a servo motor which moves the element next to the bread or away from it based on the pattering being printed. A stepper motor then moves the bread up so that the next row can be printed. All of this is mounted in a laser-cut wood frame which makes us just a bit nervous because the purpose of the elements is to burn stuff.
See a demo of the toaster, as well as its internal components in the clip after the jump.

Within a ten-hour window [Wes Brown] threw together this toaster with a web interface for one of his classes. He sourced the WIZnet embedded webserver for the project but this could be pulled off with a homebrew webserver as well. When you point your browser to the correct address you’re greeted with images of bread that have been charred to various degrees. This greatly complicates the act of making breakfast while at the same time presenting a possible fire hazard. Check out the video after the break.
