Make Something] boasts he has made probably the fanciest picture frame you’ll ever see. He started with an original sign ...

Most solar lights are cheap garbage that exist just to put more microplastics into the environment as they degrade in short order. [Jeremy Cook] built his own solar light, however, and this one ...

The project is planned on a three-acre land parcel and will feature a 42-storey residential tower as part of its initial phase. An upper circuit stock refers to the maximum percentage rise in the ...

Semiconductors are materials that have a small electronic bandgap. This bandgap prevents current from flowing at absolute zero, but thermally excited charge carriers can begin to flow at higher ...

Optoelectronic devices and components are those electronic devices that operate on both light and electrical currents. This can include electrically driven light sources such as laser diodes and light ...

Scientists have developed a low-cost visible light communication (VLC) system using commercially available hardware that enables stable data transmission even under strong ambient light. The team ...

This project demonstrates Li-Fi (Light Fidelity) communication between two Arduino boards using visible light for data transmission. Text data is transmitted using an LED and a 4x4 keypad on the ...

Abstract: A four-channel vertical cavity surface-emitting laser (VCSEL)-based co-packaged optical (CPO) transceiver (TRX) is demonstrated, integrating a photodiode (PD) array, a trans-impedance ...

Abstract: This paper presents a lesson sequence to teach programming using the Arduino platform and the free TinkerCad Circuits environment, promoting hands-on activities. The sequence supports ...
