Interesting how what started as a little discussion turned out to be one great solution at MAKE 100 as founders and owners of Staudt Technologies, Katharina and Yannic share their newly discovered solution with the world. Having realized how really difficult it is to quickly find stuff in equipped handbags, backpacks, purses, etc., the couple decided to hack a solution
f an atom gets excited in a laboratory, does it make a sound? Turns out that it absolutely does, albeit it’s the softest sound that scientists say is physically possible. Researchers at Columbia University and Sweden’s Chalmers University of Technology say that they have, for the first time, “captured” the sound a single atom makes when it
Scientists Have Captured the Sound One Atom Makes Continue Reading
Standard optocoupler speed is limited mainly by the relatively slow response of the phototransistor. This Design Idea adds components to the LED drive side to speed things up. R1 is the original LED resistor, as used before the extra circuitry was added. Here however, its value can be higher, as the turn-on speed is determined
Optocoupler speed-up also reduces power consumption Continue Reading
This project includes an analog Hall Effect sensor and an Op-Amp circuit which can be used as position or angular sensing with the benefits of no contact and wearing, high stability and wide sensing range. Two configurations of the magnet and Hall sensors are analyzed. Trimmer Potentiometer PR2 provided to adjust the offset and PR1 helps to set the

I’m a big fan of the ESP32 boards because of the number of communication options they managed to squeeze on the board, but I became more impressed recently when I came across the TTGO LoRa32 development boards which adds LoRa to the onboard communication features of the ESP32. The LoRa communication capacity of the board opens up a web

A prototype electric motor that uses a new principle for transforming electricity into rotary force is being developed at C-Motive Technologies, a company co-founded by UW-Madison assistant professor Dan Ludois. Photo: Dan Ludois A tabletop motor using an entirely new driving principle is under development at the headquarters of C-Motive Technologies, a startup business that
A vehicle and leisure battery monitor that alerts you remotely on your phone when the battery is about to be discharged beyond use. Batbot simply hooks up via two croc clips (provided) to the battery points under your vehicles bonet and can be secured in place with a cable tie. Once installed the device then

As a programming language, Lisp has been around longer than any other active language except for Fortran. To anyone who regularly uses it, it’s easy to see why: the language allows for new syntax and macros to be created fluidly, which makes it easy to adapt it to new situations, like running it on a modern
We’re all used to general purpose microcontroller boards such as the Arduino or its many imitators, but perhaps we don’t see as much of their industrial cousins. A programmable logic controller (PLC) is a computer designed to automate industrial machinery, and comes with protected interfaces and usually a specific PLC programming environment. Thus [Galopago]’s work with
