Microchip has announced a new addition to its portfolio of human interface solutions. The MTCH6303 supports touch panel sensors with up to 1000 nodes and 10 inch diagonals. The device uses signal processing to filter noise and provide predictive tracking of up to 10 fingers, at scan rates of up to 250Hz with a minimum […]
This Design Idea demonstrates a simple way to generate a multiphase clock signal, the frequency of which can be varied with minimal change in phase shift(s). The phase shift of the second output can be tuned from near zero to 180° without affecting the frequency. The basic circuit uses a minimum of parts: one cap,

The story so far Welcome to the never ending saga of Andy and his reflow controllers. About a year ago I published a project writeup showing how I built a PID-based reflow controller. It featured a 640×360 graphical LCD from the Sony U5 Vivaz mobile phone and was all-surface mount. It worked well and continues

This is version 2.0 of the previously successful kickstarter project I launched last year. I have a ton of these PCB boards left over and it got me thinking. Why not find a P channel MOSFET with the same pinout and use it to control the direction of the motor also. I looked around and

Li-ion cells become more and more popular due to their capacity and reasonable prices. In this entry I will present how to build a simple li-ion battery charger based on MCP73831 chip. It’s a quite useful device for DYI projects,in addition its cost is only around 1,5 euro. The device uses USB port as a
Fujitsu has used an ultra small package for this memory part, which it presents as a solution for power-critical miniature applications in sensor and wearable markets. The 1Mbit SPI FRAM is in an 8-pin wafer level chip scale package (WL-CSP) which is an additional package variant to the existing product MB85RS1MT. In comparison to the

The latest buzz in the information technology industry regards “the Internet of things”—the idea that vehicles, appliances, civil-engineering structures, manufacturing equipment, and even livestock would have their own embedded sensors that report information directly to networked servers, aiding with maintenance and the coordination of tasks. Realizing that vision, however, will require extremely low-power sensors that

Thermal Conductivity: A measure of the ability of a material to transfer heat. Given two surfaces on either side of a material with a temperature difference between them, the thermal conductivity is the heat energy transferred per unit time and per unit surface area, divided by the temperature difference 1. Thermal conductivity is a bulk
