Why Deep Frying Turkey Can Go Very Wrong

Tomorrow is Thanksgiving and that means Americans across the United States will be cooking up a turkey feast. One of the most popular ways to cook the bird is by deep frying it in oil.

Local TV stations everywhere spend this week warning about turkey frying. They’re not wrong… if things get out of hand you can end up burning down your house, if not your entire street. Let’s talk the science behind November turkey fires, and hopefully avoid a turkeyferno.

Simple Errors

The typical setup for deep frying a turkey involves lowering the bird into a big pot full of oil sitting on a gas burner. Ropes and pulleys are often used to lower the turkey into the pot to avoid getting one’s hands near the hot oil. Ideally, this should be done in a backyard, away from structures, to provide good ventilation and plenty of room in the case something does go wrong.

Live Jam Kit Helps Electronic Musicians Stay In Sync

Jamming live with synths and drum machines can be fun, but for [Christian], there was a little something missing. He was looking for a way to keep everyone in the group on the beat and rocking out, and decided to build something to help.

The ethos of the build was to put one person ultimately in charge of the mix using Ableton. This stops the volume race, as each musician turns their own volume up and the jam devolves into a noisy mess. Each musician also gets a sync button they can hit if their instrument has drifted out of time. Everyone in the jam also gets their own monitor signal in their headphones, as well as a looper as well.

Individual players in the electronic jam can whip up a cool little loop, and spit it out to the main controller running Ableton using the looper. Then, they can mix up something else in their headphones without disrupting the main mix, before spitting it out as a loop again.

[Christian]’s demo video does a great job of showing how it all works. We particularly like the sync button, which gets rid of the usual frustrations when a sequencer in the jam trips over the tempo signal.

It’s all built with a Teensy, and seems like a great way to organize a jam with a bunch of different synths and drum machines. We’d certainly love to join in the fun.

We’ve seen other fun jam kits too, like this neat networked solution. Video after the break.

Significantly Improved Egg Timer Makes Pictionary Better

The traditional sand timer, known colloquially as an egg timer, served its purpose well over the centuries since its development. However, [MakerPaul] realised it had some significant flaws that were ruining Pictionary, and set out to fix the problem.

If you’re not looking directly at an egg timer, it’s easy to miss the moment when the timer runs out. Resetting the timer before it runs out also requires waiting for the sand to filter to one side. Clearly the world needs a better mousetrap.

The tipping timer from [MakerPaul] solves both those issues. In this design, sand flows down into an offset area, which tips the device over when reaching a certain time limit. Additionally, turning the device upside down and then rotating it instantly reloads the sand, meaning the timer can be reused immediately.

[MakerPaul] first came up with the idea about 20 years ago, refining it during the recent lockdowns. The design files are freely available for anyone that wishes to build one. [MakerPaul] isn’t commercializing the idea, but mentions that it would be great if anyone using it makes a donation to the Mind mental health charity.

Most timers we feature are electronic and digital, but it’s easy to appreciate the elegance of what [MakerPaul] has achieved here. As a bonus, he documented the entire project and its application in under 90 seconds. How good is that? Video after the break.

GBA Remote Play Upgrade Lets You Play PlayStation On The Bus

The Nintendo Game Boy Advance was basically the handheld gaming situation of its era, by virtue of the fact that it had no serious competitors in the market. The system was largely known for 2D games due to hardware limitations.

However, [Rodrigo Alfonso] has recently upgraded his GBA Remote Play system that lets him play PlayStation games and others on his classic Game Boy Advance. We first featured this project back in July, which uses a Raspberry Pi 3 to emulate games and pipe video data to the handheld for display, receiving button presses in return.

Since then, [Rodrigo] has given the project some upgrades, in the form of a 3D-printed case that mounts a battery-powered Pi directly to the back of the console for portable play. Additionally, overclocking the GBA allows for faster transfer rates over the handheld’s Link Port, which means more pixels of video data can be clocked in. This allows for more playable frame rates when running at 240×160, the maximum resolution of the GBA screen.

The result is a Game Boy Advance which you can use to play Crash Bandicoot on the bus just to confuse the normies. Of course, one could simply build a Raspberry Pi handheld from scratch to play emulated games. However, this route takes advantage of the GBA form factor and is pretty amusing to boot. Video after the break.

Tomatoes Are Not Guncotton

[Integza] hates tomatoes, but loves rocketry. Thus, he decided to see if he could process his most-loathed fruit into some sort of rocket fuel, or at least something relatively flammable. The experiment ended poorly, but the science behind it is interesting.

The basic idea is that tomatoes are largely made up of water, sugar, and cellulose. Thus, if you nitrate that cellulose, it becomes nitrocellulose, also known as guncotton. Guncotton is was once used to replace gunpowder in firearms, though today it’s often used by magicians to create ashless flashes of flame.

To achieve this, [Integza] first attempted to make regular guncotton using a 50:50 mixture of nitric acid and sulfuric acid. The cotton was then neutralized with a baking soda and water mixture to remove excess acid, and the cotton dried. Once tested, it burned quickly as you’d expect from guncotton.

After removing the sugars from tomatoes with water, soap, hydrogen peroxide, and bleach, the tomatoes were then dried to remove excess water before also getting the acid treatment. They were then similarly neutralized, dried, and tested. One tomato did burn rather quickly, while the others merely fizzled.

One of the reasons behind this may have been due to the composition of the tomatoes. Tomatoes often consist of a mixture of cellulose, hemicellulose, and lignin, these latter components are known for producing inferior guncotton. The ramshackle preparation may have had some effect on the results. Let’s just say and it’s not advisable to work with fuming acids without protective gear and a fume hood, either.

The video’s title claims that the tomatoes were turned into rocket fuel, which is far beyond the actual results of the experiment. However, with some more advanced chemical processing, we could certainly see the fruit becoming a mite more flammable than it was. You’re probably better off just sticking to straight cotton though, for the best results. Video after the break.

Light-Tracking BEAM Robot Can See The Light

BEAM robotics, which stands for Biology, Electronics, Aesthetics, and Mechanics, is an ethos that focuses on building robots with simple analog circuits. [NanoRobotGeek] built a great example of the form, creating a light-tracking robot that uses no batteries and no microcontrollers.

The robot aims to track the brightest source of light it can see. This is achieved by feeding signals from four photodiodes into some analog logic, which then spits out voltages to the two motors that aim the robot, guiding it towards the light. There’s also a sound-detection circuit, which prompts the robot to wiggle when it detects a whistle via an attached microphone.

The entire circuitry is free-formed using brass wire, and the result is an incredibly artful build. Displayed in a bell jar, the build looks like some delicate artifact blending the past and future. Neither steampunk nor cyberpunk, it draws from both with its combination of vintage brass and modern LEDs.

It’s a great build that reminds us of some of the great circuit sculptures we’ve seen lately. Video after the break.

Cheating A Pedometer The Easy Way

These days, pedometers are integrated into just about every smartwatch on the market, and some of the dumber ones too. Tracking step counts has become a global pastime, and at times, a competitive one. However, any such competition can easily be gamed, as demonstrated by [Luc Volders].

Generally, all it takes to fool a basic pedometer is a gentle rhythmic jiggling motion of some sort. Cheaper devices will even register steps with little more than vague shaking.

[Luc] exploited this with basic machinery. A servo’s output shaft is fitted with a 3D printed cylinder, sized to allow a smartwatch to be attached as if to a wrist. Then, a Raspberry Pi Pico simply rocks the servo back and forth at regular intervals, and the watch begins counting these ersatz steps. Looking at the project as a whole, we’re betting [Luc] took some inspiration from old-fashioned automatic watch winders.

It’s hard to envision an important application for this technology. However, if one is in a friendly competition with friends who don’t scrutinize the results too closely, this would be an easy way to win.

Alternatively, consider building a pedometer to track your hamster’s exercise regime. If you’ve got your own exercise hacks on the go, drop us a line!
