A new die shoot from zeptobars.com. Die size 1547x1279 µm. ST TL072 - dual JFET opamp die-shot -...

Anthony Smith @ edn.com published a push button latching circuit able to control a load with a single push of a button. The circuit in Figure 1 shows how you can use a simple, momentary-action, SPNO (single-pole, normally open) pushbutton switch to latch power to a load. Requiring...

Keith Szolusha@ edn.com writes: In certain dc/dc-converter applications, on-chip, cycle-by-cycle current limit may be insufficient protection to prevent a failure during a short circuit. A nonsynchronous boost converter provides a direct path from the input to the short circuit...

This is a wireless digital scale using ATTiny85 microcontroller and HM-10 Bluetooth low energy transmitter/receiver: This scale is wireless. It may be useful where you can't operate a normal scale, due to the weather outside, or if you don't want to scare birds or other creatures...

This PIC microcontroller based RC driver is able to control 4 RC Servo by on board independent 4 potentiometer , 4X3PIN header for RC servo interface, screw terminal for supply input, on board power LED, optional 4X3PIN header connector for external potentiometer. Features...

This project is a wifi synchronised desktop clock using 7-segment displays. The heart of the project is a ESP8266 board. The ESP8266 is a awesome chip; with integrated WiFi, 80MHz clock speed, total 160kb RAM, 512kb of flash memory, and a ton of other features, it makes a regular...

This project shows how to measure temperature data from a TSYS01 Temperature Sensor board using Arduino: While studying in university we were challenged as part of a course work into designing a box with very accurate temperature control. If the project were to succeed, multiple...

Michael Dunn@ edn.com discuss about current sense on the high side of power source. At their heart, the majority of DC current sense circuits start with a resistance in a supply line (though magnetic field sensing is a good alternative, especially in higher-current scenarios). One...
