Remember the old video game Space Invaders? Some of its sound effects were provided by a chip called the 76477 Complex Sound Generation chip. While the sound effects1 produced by this 1978 chip seem primitive today, it was used in many video games, pinball games. But what’s inside this chip and how does it work […]

The Design Idea in Figure 1 indicates a low-battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all-discrete design, this same approach seemed more in keeping with the spirit of the project than the use of a single-sourced integrated circuit. A garden-variety red LED
Simple circuit indicates a low battery Continue Reading
Gateworks Corporation announces the Newport Family of single board computers featuring eight standard models. These models range in size and features to provide a comprehensive and flexible solution to customers requiring a high performance, feature-rich embedded networking board. The Newport Family is based upon the Cavium Octeon TX 64-bit ARMv8 SoC, which has been designed
Newport Family of SBC Based on the Cavium Octeon 64-bit ARMv8 Processor Continue Reading
Normally -according to the Ohm’s law– when the applied voltage is increasing, the current is increasing too, however some components can break this law. When the voltage increases, current decreases. This is called negative resistance. One of the most know element that exhibits this behavior is a tunnel diode. Once very promising, today it isn’t
Simple negative resistance oscillators Continue Reading
Engineers at the University of Bristol have developed a three terminal pico-power chip that can cut standby drain in sensor nodes – even compared with today’s low-power microcontrollers. It does this by replacing the low duty-cycle sleep-wake-sleep pattern used on MCU-based sensor monitors, with ‘off’. A voltage detector powered by the sensor – there is

I bought a couple of IXYS linear MOSFETs (IXTK90N25L2) a while ago to test their capabilities when used as electronic load, and the result was quite impressive. So I decided to build another electronic load using both MOSFETs. As you can see in the video towards the end, this electronic load can sink more than
