This machine helps to experimentally find an estimation of absolute zero
Reading Time: 2 minutesHow can we ever really know anything? If you listen to the anti-science types, you might believe that we can’t. But if you get past Plato’s Allegory of the Cave, you can start identifying basic truths, through logic and experiments, on which to build upon. One important foundational building block is absolute…

This student made his own odds with a DIY slot machine
Reading Time: 2 minutesToday’s digital slot machines are anything but “fair,” in the way that most of us understand that word.

Quickly digitize your Magic deck with this 3D-printable scanning rig
Reading Time: 2 minutesWe call them “deck builders” for a reason: because players end up with huge piles of trading cards. They can get difficult to manage, which is why the ManaBox app exists for Magic: The Gathering. It lets collectors scan and log their decks, which is handy for everything from finding market values to…

DIY micro lab analyzes ammonia levels in blood and urine
Reading Time: 2 minutesCirrhosis of the liver is an extremely serious condition that requires extensive medical monitoring and often intervention. Progression of the condition can be fatal, so even if caught early it must be monitored closely. But, like most things in medicine, that gets expensive. That’s why Marb built his own DIY “micro lab”…

A Game Boy is the worst and best option for a car’s dash
Reading Time: 2 minutesIf your car was made in the last decade, its dash probably has several displays, gauges, and indicator lights. But how many of those do you actually look at on a regular basis? Likely only one or two, like the speedometer and gas gauge. Knowing that, John Sutley embraced minimalism to use…

This telescope can intelligently point itself anywhere in the sky
Reading Time: 2 minutesKnown by their characteristic mounting solution, Dobsonian telescopes are the standard in amateur astronomy due to their lower cost and ease-of-use. But after seeing how some of the larger, motorized telescopes at observatories can simply pivot to a target of interest, one member from the FabLab at Orange Digital Center Morocco wanted to…

This autonomous go-kart only needs a camera to navigate a workshop circuit
Reading Time: 2 minutesAutonomous vehicles, and self-driving cars in particular, are probably one of the most enticing technologies of the 21st century. But despite a great deal of R&D and even more speculation, we have yet to see a self-driving car that can actually operate on real public roads without any human oversight at all.…

Turn your old Android smartphone into an Arduino screen with the RemoteXY app
Reading Time: 2 minutesEach component you add to your Arduino project increases its complexity and the opportunity for mistakes. But most projects require some “auxiliary” hardware — components that you use to interact with the Arduino or to help it do the job you’re asking of it. Buttons and displays are great examples. But as…

This fake CRT TV works using lasers and UV magic
Reading Time: 2 minutesUntil the 21st century, cathode-ray tube (CRT) TVs were pretty much the only option. As such, media was made to suit them. Retro video game consoles in particular look best on CRT TVs. But those old TVs are getting hard to find and desirable models are now quite expensive. So, bitluni built his…
