There are many producers of wires, leads and cables, but despite it, company LappKabel belongs to one of the most renowned. What´s the cause? Exceptional place on the market started in 50-s, when company LappKabel started as the first in this segment to name its products (Olflex). Together with high and stable quality, LappKabel has […]

Rohde & Schwarz designed the new 200 MHz models of the R&S RTM oscilloscope especially for universities and educational institutions. The education mode was developed for test and measurement practica and makes it possible to disable all analysis tools (e.g. Autoset and QuickMeas) and automatic measurements. This improves the learning effect as students and learners […]

Recently I got a project from Titan industries, who were in search of something as an interactive plant pot which could bridge this gap of emotional communication, in mins this reminded me of brilliant projects done by people where the plant could could tweet and send mails and txts and on your command over the […]

I teach Modern Physics here at CSUC, and we occasionally use isotopes with half-lives of a year or less (such as Zinc-65 and Cadmium-109) for energy-calibration sources for a gamma-spectroscopy lab. I thought it might be fun to try measuring the activity of one of these sources over time and thus get a looooong-scale half-life […]

One of the most fun and useful projects on instructables is to create your very own solar USB/ iPhone charger. They’re not overly difficult to make, nor are the parts overly expensive or hard to find. For the most part they do a rather good job of charging up small gadgets. Mostly. The big flaw […]

The MAX21002 is a low-power, low-noise, dual-axis angular rate sensor that delivers unprecedented accuracy and sensitivity over temperature and time. It operates with a supply voltage as low as 1.71V for minimum power consumption. It includes a sensing element and an IC interface that provides the measured angular rate to the external world through a […]

A plane powered by the sun, the Solar Impulse 2, has left Switzerland in a cargo flight bound for Abu Dhabi. Once there, it will attempt a flight around the world, over India and China, taking in Hawaii and the rest of the US before crossing the Atlantic to southern Europe, northern Africa and completing […]

If you have looked at my 5 LED ATtiny85 POV display, we programmed the ATtiny with the Arduino. (If you haven’t seen it, click here) We will be doing the same thing for this LED Dice project. The total parts cost for this project is about $5-$10. (Not including the Arduino board and the tools.) […]

Widespread adoption of cameras in smartphones and other mobile devices, together with consumer expectations for higher quality, sharper images are driving the need for simpler designs, smaller sizes, and lower component counts, particularly as many smartphones move to integrate front- and back-facing cameras. Mobile phone cameras will increase from approximately 1.6 billion units in 2011 […]

My kids are learning Morse code this summer, so I threw together this little circuit to help them learn. And to make it more fun… It uses an ATtiny85 ($2.26 at digikey.com) to drive a piezo beeper (≈ $3.50 at Radio Shack.) The ATtiny85 takes 5.5V max, so I built the circuit on a piece […]
