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 […]
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

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
New LED Photo Flash Drivers for Smartphone Cameras Improve Image Quality Continue Reading
My friend Jonathan Ward and the rest of the team at Otherfab have posted their new CNC milling machine, the Othermill, to KickStarter. This is a robust, low-cost machine for milling circuit boards, wax molds, wood, aluminum and more. The machine is made from high density polyethylene with an ingenious snap-fit mechanism that’s strong, reversible,
An RGB LED and 3-axis accelerometer enable thousands of applications without requiring any modifications. Create a motion alarm to warn you if someone moves your bike. Get wireless notifications for text messages, emails, and Facebook posts. Build an iPhone-controlled Nerf gun turret. The possibilities are endless. Want even more applications? Pre-Order four Cortados and get

Introduction “The sound and experience of drums… Any time, anywhere, with any object.” -Project Soundbyte It’s Friday night and you’re hanging with your friends at home. There are no parties tonight and you have seen everything on Netflix already – you’re bored out of your minds. One of your friends pulls out his portable roll
Cheap and modular drum system Continue Reading
Moving on from the last chapter where we explained an 8-bit ADC, in this instalment we have the Texas Instruments ADS1110 – an incredibly tiny but useful 16-bit analogue-to-digital converter IC. It can operate between 2.7 and 5.5 V so it’s also fine for Arduino Due and other lower-voltage development boards. This is a quick guide

Introduction For our final project, we have decided to use the microcontroller provided to make a device which would measure body fat percentage of one’s body. The basic principle behind this project is known as bioelectrical impedance analysis. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine

The basis for this tube preamplifier started out as a post in the Super simple single stage tube preamp thread on the website Forum. One of the members (see Mark’s 4S Universal Valve Preamps) had suggested building a Super Simple Single Stage Preamp (“4S” Preamp for short) and there was much discussion concerning various tubes,
