I have built a GPS Logger and it works very well to trace the drove route for two years. By the way, the navigation solution computed by GPS receiver itself has an excellent accuracy without DGPS because an intentional offset added by US goverment has been stopped several years ago. The position error seems to

This is an example of a simple and cheap milliohmmeter that can be made by every maker. The core of the circuit are a current source (LT3092) and a current sense (INA225): a costant current flows through the milliohm resistor under test and the voltage at the current sense output gives the value of the

This reference design is an anti-drowsiness alarm, which aims to keep the drivers alert by disrupting oneās drowse. According to the study by U. S. National Highway Traffic Safety Administration (NHTSA), drowsy driving is the primary contributor of at least 100,000 auto crashes a year. Statistics shows that most crashes caused by drowsy driving occur

A few months ago, Andreas presented a nice version of the “throwie” (a LED packed with a small battery that you can throw & see shining for hours) using an ESP8266 instead of a LED : a “wifi throwie”. He could not make it work with button cell batteries (the ESP8266 draws too much current)

Although Intersil’s ISL29501 time-of-flight (ToF) signal processing IC doesn’t have anything to do with the lighting applications I normally cover, I felt compelled to bring it to your attention because it’s one of the most innovative LED applications I’ve seen this year. The device requires little more than an external emitter (LED or laser) and
