This post is different from normal Hackaday fare. I don’t want to presume anything about you, but I’m pretty sure the story I’m about to share resonates with at least some of you.
I’ve been having a tough time, exacerbated by this age of social distancing. This all crept up on me at first, but as I began to look back on my behavior and moods, I began noticing patterns that I hadn’t noticed before. This is certainly a relevant issue in this community, so let’s talk about mental health, beginning with my own journey.

[Rickysisodia] had a few dead ATmega128 chips laying around that he didn’t want to just throw away, so he decided to turn them into his own light-up fidget toy. The toy is in the form of a six-sided die so small that you can hang it on a keychain. He soldered an ATmega128 on each side of the cube and added a few dot circles to give his toy the look of a functional dice. We were pretty amazed by his impressive level of dexterity. Soldering those 0.8 mm-pitch leads together seems pretty tedious if you ask us.
Then he wired a simple, battery-powered tilt switch LED circuit on perfboard that he was able to sneakily place inside the cube. He used a mercury switch, which, as you may figure, uses a small amount of mercury to short two metal contacts inside the switch, completing the circuit and lighting the LED. We would suggest going with the non-mercury variety of tilt switches just to avoid any possible contamination. You know us, anything to mitigate unnecessary disasters is kind of a good route. But anyway, the die lights up a different color LED based on the orientation of the cube and it even blinks.
This is a pretty cool hack for wowing your friends at your next PCB art meet-up. We’ll probably put this in the electronics art category, so it doesn’t get lumped in with those other ever-beloved fidget toys.

What makes you afraid? Not like jump-scares in movies or the rush of a roller-coaster, but what are your legitimate fears that qualify as phobias? Spiders? Clowns? Blood? Flying? Researchers at The University of Texas at Austin are experimenting with exposure therapy in virtual reality to help people manage their fears. For some phobias, like arachnophobia, the fear of spiders, this seems like a perfect fit. If you are certain that you are safely in a spider-free laboratory wearing a VR headset, and you see a giant spider crawling across your field of vision, the fear may be more manageable than being asked to put your hand into a populated spider tank.
After the experimental therapy, participants were asked to take the spider tank challenge. Subjects who were not shown VR spiders were less enthusiastic about keeping their hands in the tank. This is not definitive proof, but it is a promising start.
High-end VR equipment and homemade rigs are in the budget for many gamers and hackers, and our archives are an indication of how much the cutting-edge crowd loves immersive VR. We have been hacking 360 recording for nearly a decade, long before 360 cameras took their niche in the consumer market. Maybe when this concept is proven out a bit more, implementations will start appearing in our tip lines with hackers who helped their friends get over their fears.

You’ve just finished your project. Well, not finished, but it works and you’ve solved all the problems worth solving, and you have a thing that works for you. Then you think about sharing your creation with the world. “This is cool” you think. “Other people might think it’s cool, too.” So you have to take pictures and video, and you wish you had documented some more of the assembly steps, and you have to do a writeup, and comment your code, and create a repository for it, maybe think about licensing. All of a sudden, the actual project was only the beginning, and now you’re stressing out about all the other things involved in telling other people about your project, because you know from past experience that there are a lot of haters out there who are going to tear it down unless it’s perfect, or even if it is, and even if people like it they are going to ask you for help or to make one for them, and now it’s 7 years later and people are STILL asking you for the source code for some quick little thing you did and threw up on YouTube when you were just out of college, and of course it won’t work anymore because that was on Windows XP when people still used Java.
Take a deep breath. We’ve all been there. This is an article about finding a good solution to sharing your work without dealing with the hassle. If you read the previous paragraph and finished with a heart rate twice what you started, you know the problem. You just want to share something with the world, but you don’t want to support that project for the rest of your life; you want to move on to new and better and more interesting projects. Here are some tips.

Navy SEALs and other highly trained special forces operators all know a simple, basic fact – you’ve got to breathe to live. That seems self-evident, but breathing control is immensely important to being able to perform at a high level in stressful situations. But even if you never anticipate being under fire, you can learn the SEAL way of breathing with this visual aid.
Lest you think that Box Breathing, also known as the four-square breathing technique, is some sort of New Age nonsense, recent research has uncovered the neurological basis for the feeling of calm that can come over someone taking slow, deep, even breaths. But in the heat of the moment, remembering to square your breaths can be a little difficult. [Lim Han Yang] decided that a portable visual cue could help, so he put an ATTiny85, an LED, and a coin cell battery on a tiny circular PCB and spun up a simple translucent dome out of PLA. The blue LED has a soothing appearance behind the diffuser as it goes through a 16-second cycle, ramping up in brightness for four seconds, holding steady for four, then dimming and finally staying dark. The idea is to breathe in sync with the light to get relief from stress.
No build files are posted yet, but we hope to see them soon – we can think of a few people this would benefit greatly. In the meantime, if you’re still looking for that New Age breathing experience, you can always breathe with the psychedelic flowers.
