What if you were to use the hands of a clock not as an individual display, but as part of an array combines together to form digits? That’s the idea behind Clockception by creator “Made by Morgan,” which utilizes 48 servo motors to drive 24 clock-like faces for an 8×3 display.
The build uses an Arduino Nano and three servo driver boards to control movement, along with a DS1302 RTC module to track time. The overall clock is constructed out of stained poplar, while the dial assemblies are 3D-printed.
Clockception was actually inspired by the ClockClock project by Humans Since 1982, but by using his own design and DIY methods, he was able to get the cost down to around $200.
Overall computer volume control is important, but what if you want to get more granular, adjusting sound from various applications individually? Rather than going through a series of menus and on-screen sliders, Ruben Henares’ Maxmix lets you do this on the fly.
Based on an Arduino Nano, the simple yet stylish knob takes input from an encoder and button to cycle through and select a program. Just push down and then rotate to turn the volume up or down. Want to switch from Discord to Spotify? Click it again and repeat the process.
A small OLED screen on the Maxmix shows which app is running, and there’s even an optional LED ring for extra lighting effects. All the electronics are housed inside a nicely designed 3D-printed enclosure.
You can find the build instructions on Henares’ site and see a demo of it below.
DIY camera sliders are a great way to get professional-looking video shots on an amateur budget, but few can compare to the quality of this project by “isaac879.”
His device features a pan/tilt mechanism outlined in a previous video, but in the clip below he’s attaching it to a piece of aluminum extrusion to enable it to slide as well.
The build is controlled by an Arduino Nano, which actuates three stepper motors using A4988 drivers. The carriage is pulled along by a belt drive, via a stepper mounted to the carriage itself. This allows for easy disassembly when needed.
It’s a clever and extremely clean design, and the video shows some great examples of the shots it can take (even when upside down).
Er13k was inspired to create an Arduino music box to go along with his girlfriend’s giant stuffed dog Tobias. This eventually morphed into something that not only plays songs on its own speaker, but also lights up a 3D-printed keyboard with LEDs. Perhaps its coolest feature, though, is that it includes an RCA output jack to show a cartoon representation of the plush toy on a CRT television.
When the AV output is active, the device pushes tunes through the TV’s speaker and displays 95×95 pixel drawings and simple animations.
You can see it demonstrated in the video below, as well as some of the build process. On his “channel,” Tobias gets hungry, makes a drawing, and… becomes quite unsatisfied with his job.
After mechanical engineer “Kuchbert” saw the hip-hop/electropunk band Deichkind perform — wearing LED-embedded tetrahedral hats, no less — he decided he wanted his own glowing geometric headpiece. Now, nearly 10 years and several shows later, he finally got his wish by constructing one out of acrylic triangles with 156 WS2812Bs.
An Arduino Nano controls the device, which links up to an Android app via an HC-06 Bluetooth module, while a portable USB power bank keeps things running.
If you’ve ever seen a gigantic air dancer on the side of the road and thought you might want one of your own, Davide Marin shows how to create a desktop version here. The flailing figure is constructed out of trash bags that are cut and melted into shape, and designed to stand and dance via a centrifugal blower assembly.
An Arduino Nano board is used to control the waving inflatable’s fan, along with a MOSFET to turn it on and off. A servo can optionally be implemented to direct air output back and forth to make things even crazier.
It looks like a lot of fun, as seen in the videos below!
