| The external appearance of this small module with an LC display almost belies what it has inside: a complete stereo preamplifier and final a...
| High-brightness LEDs are being used more and more widely in lighting applications. Here we present a simple ‘mood light’ using just a few co...
| The devices described here are tailored to fit the needs of modern DSPs, processors and FPGAs that require low supply voltages at relatively...
| The TPS6420x controller is designed to operate from one to three series-connected cells or from a 3.3 V or 5 V supply obtained from a USB po...
| If a device fails to respond to an IR remote control unit, the problem is often in the remote control, and it usually means that the batteri...
| For many applications, programming a microcontroller after it has been soldered to the circuit board in the target application is more conve...
| Two logic devices from revered Texas Instruments, the SN74AUP1T97 and ‘98 are logic glue components in tiny SOT23 cases. As shown in the dia...
| This technique for modifying standard predrilled prototyping stripboard (‘perfboard’ or veroboard’) to accept SO IC packages is intended to...
| The circuit described here is mostly aimed at development engineers who are looking for an economical step-down converter which offers a wid...
