Avishek Hardin at Arduino Project Hub designed a lightweight mobile using a GSM module, an Arduino UNO, and a Nextion touch screen display. The lightweight mobile has the following features: Make calls Receive calls Send SMS Receive SMS Delete SMS In this project, he uses a GSM SIM900A module to establish the cellular communication. The GSM SIM900A is an […]

The common magnetic loudspeaker is, fundamentally, a fairly simple machine. A static magnetic field is generated by a permanent magnet, and a membrane is mechanically connected to a coil. When a varying electrical current is passed through the coil, this causes the coil to move due to the magnetic field, vibrating the membrane and producing

Fans of HiFi sound and similar „audiophils“ usually don´t cover their loudspakers and surely not their membranes. Firstly, to cover a beautiful top-class loudspeaker is almost a sin 🙂 and naturally all that stands in a way of sound usually influences it in a negative way. However, totally different situation is in traffic, audio bells,

The Soundlazer directional audio project is the continuation of my first and very successful project here on Kickstarter. I developed the Soundlazer “Snap” during my quest to lower the cost of this amazing technology and give backers the opportunity to explore new possibilities in directional audio. Parametric speakers like the Soundlazer are directional speaker systems.
