This stepper pulse generator project is an easy solution for stepper controller drive. It’s a very important tool and can be used to drive stepper in standalone mode. It generates square wave pulses in frequency range 0-50Khz. This project has multiple features which are a must for...

Researchers developed a multijunction solar cell on a GaSb substrate that can efficiently convert the long-wavelength photons typically lost in a multijunction solar cell into electricity. This prototype cell has an efficiency of 44.5% which is higher than conventional solar cells. A...

Researchers from the MESA+ research institute at University of Twente have collaborated together with the provider company of the customized microsystem solutions "LioniX International" to achieve the lowest bandwidth tunable diode laser on a chip. The newly-developed laser operates...

Here is a nice die-shot of LM555CMX @ zeptobars.com Fairchild LM555CMX : weekend die-shot -...

Besides looking damned good on an otherwise bland and ordinary desk, this project is about more than just being attention grabbing eye candy.  It’s about demonstrating a small portion of our single board computer capabilities by hooking up a color sensor, RGB light strip, and...

MellBell, the Canadian-based hardware and electronics company, has launched their first product: Arduino PICO! At first, the company says that Arduino PICO is the smallest Arduino compatible board ever, since it is 0.6" x 0.6" inch sized (~15mm squared). This tiny fully-fledged...

Romeo BLE is an all-in-one Arduino based control board specially designed for robotics applications from DFRobot. This platform is open source and it's powered by thousands of publicly available open-sourced codes. Romeo BLE can easily be expanded using Arduino shields. The most important...

by Mechanical Attraction @ instructables.com: There is energy everywhere around us and in many different forms. Many devices have been developed to harvest light, wind, waves, and more. One unusual place of energy harvesting is from passing cars. As cars pass by some of their energy...
