Space Trash Game Using Arduino and OLED Display

“Dear friends, Welcome to Pi BOTS MakerHub. Today we are going to make a Game using Arduino and OLED Display. I recommend using the 128x64 pixels OLED display with I2C or SPI Communication, and a smaller Arduino like PRO Mini …

Sprayable user interfaces

“CSAIL’s SprayableTech system lets users create large-scale interactive surfaces with sensors and displays using airbrushed inks. For decades researchers have envisioned a world where digital user interfaces are seamlessly integrated with the physical environment, until the two are virtually …

Temperature Measuring Automatic & Voice Inform

“Recent day, whole world is struggling with virus Covid19. First checking for effected people (or suspect to be effected) is measuring body temperature. So this project is made to model that can measure body temperature automatically and inform by voice …

Thanks to “flexoskeletons,” these insect-inspired robots are faster and cheaper to make

“Engineers at the University of California San Diego have developed a new method that doesn’t require any special equipment and works in just minutes to create soft, flexible, 3D-printed robots. The innovation comes from rethinking the way soft robots …

This Spectrum Analyzer Sputnik Shines a Light on the Sounds Around

“Looking like something straight out of a sci-fi film, this steampunk Sputnik sculpture shines out in response to the sound around it. Mohit Bhoite is back again, and this time with a “stellar” example of his circuit crafting skills, in …

UNC-Chapel Hill researchers develop one-way street for electrons

“Research may unlock the ability for devices to process ultra-high-speed wireless data and simultaneously harvest energy for power. Researchers at the University of North Carolina at Chapel Hill made a one-way street for electrons that may unlock the ability for …

Use a Stepper Motor As a Rotary Encoder

“Rotary encoders are great for use in microcontroller projects as an input device but their performance is not very smooth and satisfactory. Also, having a lot of spare stepper motors around, I decided to give them a purpose. So if …
