1 This design features a wireless power transmitter that supports Qi enabled smartphones and other devices. It operates from a 4.5 - 6.9V input and supports up to 8W power transfer at approximately 1.6A. The low cost adaptors and other unregulated adaptors or supplies help prevent surges. Because, it is a fully integrated design, BOM cost is minimal while still offering highly efficient operations with very low RDS(ON). It also has programmable input in-rush control that can be used to add up protections and configurations...Open Project

2 This project is a password based digital locking system using a microcontroller. It is another type of security structure that asks users to enter a predefined password before allowing access to protected appliances, doors or other systems. The circuit utilizes the dynamic series connectors from TE connectivity to provide a reliable and strong connection in between components...Open Project

3 The reference design as shown is a phase angle control for universal motors. This circuit is used to control the speed of a universal motor. A universal motor is a commutated series wire-wound DC motor. This circuit uses phase angle control to vary the effective motor voltage. The basic principle of the phase angle control algorithm is simple: match the firing pulse time of the triac in relation with the zero crossing of the line voltage. A phase shift of this firing pulse produces a variable output voltage on load... Open Project
