Working with electronics requires access to stable power in a variety of voltages. Some components require 3.3V and others require 5V. Still others need 9V or 12V — there are many possibilities. You could keep a variety of wall warts on hand, but a variable benchtop power supply is a more convenient option. Supplino is […]
Maker Bradley Campbell is looking to become the next Sorcerer Supreme by building his own, working Eye of Agamotto using an Arduino.
While thinking of an interesting project to create, Hackster user marcaubin started to imagine an audio spectrum visualizer, but not a traditional one that has a matrix of LEDs with columns corresponding to certain frequencies. Instead, his device would have just a single vertical NeoPixel strip featuring 29 LEDs in total, with the bottom ones displaying the […]
Portable air conditioners are amazing, especially as we head into the hot summer months. But one big downside is having to place them close to a window that will fit the guard, otherwise it’s really tough getting the hot exhaust air out of the room. This is exactly the problem Hackaday user vincentmakes ran into when he […]
MIDI-controlled instruments are awesome, as custom sounds can be loaded and dynamically changed while you play. However, accessing these effects often requires an external controller that can get expensive and complicated. That is why music enthusiast Joe King created the Stryde, which is a fully integrated MIDI preset loader within a small enclosure. Stryde uses […]
As spotted on Reddit, the Light Based Optical Productivity Enhancement System (LOPES) is an Arduino Nano Every-powered device that lights up depending on the tasks that you have left to complete. The Nano takes input from five copper touch sensor plates on the top, which enable you to add or remove jobs of different priorities. […]
Sunrises can be beautiful, not to mention sunsets, but seeing both at one time would seem to be an impossibility. Dries Depoorter, however, has developed an installation that displays the two events as they happen on side-by-side screens, using footage sourced via unsecured CCTV cameras. Depoorter’s “24h Sunrise/Sunset” project uses a pair of Raspberry Pi 3Bs to […]
It’s generally not advisable to leave equipment running when unattended. As a safeguard against this possibility at hackerspaces and elsewhere, element14 Presents’ Dave Darko built a custom switch that requires users to intermittently push a button in order to produce additional ‘on’ time. The trick here is that instead of having one keep-alive button, the unit has […]
For his school science fair, Mars Kapadia decided to take things up a notch and create his own pair of smart glasses. The project, which went on to place in the state competition, uses a transparent OLED display to show info from Retro Watch software running on an Android phone. The wearable device is controlled by […]
