AN ARDUINO-FREE AUTOMATIC ALCOHOL ADMINISTRATOR

With all the hands-free dispenser designs cropping up out there, the maker world could potentially be headed for an Arduino shortage. We say that in jest, but it’s far too easy to use an Arduino to prototype a design and then just leave it there doing all the work, even if you know going in that it’s overkill. [ASCAS] took up the challenge and built a cheap and simple dispenser that relies on recycled ...

OPEN SOURCE TELESCOPE CONTROLLER PUTS SMART FEATURES IN OLD TELESCOPES

In times like these, we all need to look beyond ourselves. This project might help: OnStep is an open-source telescope controller, a device that controls a telescope to point at something interesting in the sky. Want to take a look at M31? Use an app on a PC or smartphone, select the object and the OnStep will pan and tilt your telescope until the Andromeda Galaxy pops into view. Smart telescopes are not ne ...

MINIMALIST MAGNETIC MINUTE MINDER MESMERIZES

Timepieces are cool no matter how simplistic or granular they are. Sometimes its nice not to know exactly what time it is down to the second, and most of the really beautiful clocks are simple as can be. If you didn’t know this was a clock, it would still be fascinating to watch the bearings race around the face. This clock takes design cues from the Story clock, a visual revolution in counting down time wh ...

THE ATTINY SERIES IS A GREAT COMPANION IN ISOLATION

As a consequence of the social distancing and self isolation, many a maker has been searching for ways to cure boredom. So what happens when you put a maker in a closed space with electronics parts. The answer is a bunch of random microcontroller projects that help beat boredom. [Danac1886] posts a video with a bunch of experiments with the ATtiny series of microcontrollers which can be a source of time-kil ...

USING A VENDING MACHINE BILL ACCEPTOR WITH ARDUINO

We’ve all seen, and occasionally wrestled with, bill acceptors like the one [Another Maker] recently liberated from an arcade machine. But have you ever had one apart to see how it works? If not, the video after the break is an interesting peak into how this ubiquitous piece of hardware tells the difference between a real bill and a piece of paper. But [Another Maker] goes a bit farther than just showing th ...

BCD TO I2C: TURNING A NIXIE COUNTER INTO WHATEVER YOU WANT IT TO BE

Whenever a project calls for displaying numbers, a 7-segment display is the classic and straightforward choice. However, if you’re more into a rustic, retro, almost mystical, and steampunky look and feel, it’s hard to beat the warm, orange glow of a Nixie tube. Once doomed as obsolete technology of yesteryear, they have since reclaimed their significance in the hobbyist space, and have become such a frequen ...

SELF-PLAYING WHISTLE WHILE YOU WORK FROM HOME

In ridiculous times, it can help to play ridiculous instruments such as the slide whistle to keep your bristles in check. But since spittle is more than a little bit dangerous these days, it pays to come up with alternative ways to play away the days during lockdown life. Thanks to some clever Arduino-driven automation, [Gurpreet] can maintain a safe distance from his slide whistle while interacting with it ...

AUTOMATING HAND SANITIZER — IF YOU CAN FIND ANY

We once saw a Romeo and Juliet production where the two families were modern-day mob families with 3-piece suits and pistols. If they made King Richard III set in this week, the famous line might be: “Hand sanitizer, hand sanitizer, my kingdom for hand sanitizer!” Even if you have a supply stashed in your prepper cache, you have to touch the bottle so you could cross-contaminate with other users. Public pla ...

ANOTHER PC POWER SUPPLY PROJECT

Economy of scale is a wonderful thing, take the switch-mode power supply as an example. Before the rise of the PC, a decent multi-voltage, high current power supply would be pretty expensive. But PCs have meant cheap supplies and sometimes even free as you gut old PCs found in the dumpster. [OneMarcFifty] decided to make a pretty setup for a PC supply that includes a very nice color display with bargraphs a ...

EAVESDROPPING ASSISTANT DISTURBS THE SOUND OF SILENCE

Unless you happen to be from Finland, this is just an all too familiar situation: you’re stuck in an inescapable situation with this one person who is really more of an acquaintance than a friend, and neither of you knows who should say something in hopes of keeping a conversation going. Awkward silence is inevitable, and the longer it lasts, the more excruciating the thought of opening your mouth becomes. ...
