POV Tops Hobbyist Abilities

Sometimes a beautiful project is worth writing on that merit alone, but when it functions as designed,someone takes the time to create a thorough and beautiful landing page for their project, we get weak in the knees. We feel the need to grab the internet and point our finger for everyone to see. This is one of those projects that checks all our boxes. [Nathan Petersen] made a POV toy top called Razzler, jumping through every prototyping hoop along the way. The documentation he kept is what captured our hearts.

The project is a spinning top with an integrated persistence-of-vision …read more

Building a POV Display On A PC Fan

We’ve covered plenty of persistence of vision (POV) displays before, but this one from [Vadim] is rather fun: it’s built on top of a PC fan. He’s participating in a robot building competition soon and wanted to have a POV display. So, why not kill two birds with one stone and build the display onto a fan that could also be used for ventilation?

The display is a stand-alone module that includes a battery, Neopixels, Arduino and an NRF240L01 radio that receives the images to be displayed. That might seem like overkill, but putting the whole thing on a platform …read more

Luckily for him (and us) the Winter Olympics have started, which ended up being the perfect guise for this particular experiment. With some motors from eBay and some flaming steel wool, he created a particularly terrifying version of the Olympic’s iconic linked rings logo. Even if you won’t be tuning in for the commercials Winter Games, you should at least set aside 6 minutes to watch this build video.

The beginning of the …read more

Finally, A Fidget Spinner We Can Love

We’ve been frankly mystified at the popularity of fidget spinners. After all, we can flip an ink pen around just fine. However, [MakersBox] just sold us on what he calls the geek spinner. The fact that the spinner is actually a PCB and has parts on it, would probably have been cool enough. However, the spinner also has a persistence of vision LED set up and can display 12 characters of text as it spins. Because the board is simple and uses through hole components, it would be a great project for a budding young hacker. You can see a …read more
