LOW-POWER BUTTON REPLACEMENT WITH FORCE-SENSITIVE RESISTOR

LOW-POWER BUTTON REPLACEMENT WITH FORCE-SENSITIVE RESISTOR

Introduction A common requirement for devices that must be sealed from environmental exposure is to replace all metal contact style push-buttons with functional replacements that do not have those weather-sealing difficulties. This article describes one such way of creating a contact button replacement using a Force-Sensitive Resistor (FSR) in conjunction with an SLG47004V. Design Description …

RF Motion Controlled Robot

Introduction For our final project, we designed and implemented a remote-control car with a user-controlled steering wheel interface. We wanted a user interface that was immediately intuitive and familiar, which we thought a steering wheel with an onboard accelerometer definitely accomplished. Additionally, we wanted a system that could realize reliable real-time remote communication, so we …

Friwo LED drivers will light up your LEDs as much as you just want

Friwo LED drivers will light up your LEDs as much as you just want

LT series LED drivers with 10-100W power represent a complete solution with wide possibilities of control. Exceptionally narrow and slim design, remained even at high-power versions, provides a high flexibility of use. Power supplies for LED lighting (so called drivers) are available from many producers, in a various qualitative level. Why to decide just for …

Sensing current on the high side

Sensing current on the high side

As EDN’s Design Ideas editor, I see a range of design submissions, from good, to not so good. A recent DI I turned down for several reasons included a high-side current sense circuit with implementation problems. This got me thinking about the different ways to accomplish current sensing on a voltage rail. At their heart, …
