I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

In this paper, we use the Arduino platform together with sensors as accelerometer, gyroscope and ultrasound, to measure vibrations in mechanical systems. The main objective is to assemble a signals ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...

[Todd Harrison] really has our number. Like him, we don’t want to spend money when we don’t have to, and hacking our own solutions is a lot more fun anyway. This time around he’s helping out a friend ...

While developing a vacuum system used for homemade PVD sputtering aparatus I felt the need of a simple and cheap vacuum gauge that can measure pressures as low as 1 Pa. I was not able to find online a ...

Abstract: This work aims to demonstrate the capability of a low-cost experimental setup to monitor surface plasmon resonance (SPR) chemical sensors based on plastic optical fibers (POFs) and ...
