Use the Force… or Your Brainwaves? (multifuctional Thought Controlled System)

As a kid I always wanted to have a special ability, like moving objects with thoughts or flying. I tried to move objects with “the power of my mind” of course with no success. Well, yes, I was and I am a huge Star Wars fan, but I also like electronics and programming, so why not combine these two things to build an incredible project? You can find all parts, codes and libraries with links at the Hardware an ...

The “Neuropixels” probe records brain signals

After $5.5 millions collaboration and a lot of work during the past four years of engineers at Imec, the next-generation electrodes called Neuropixels probe were designed to record hundreds of neurons in the brain. Imec is an international nano electronics research center dedicated to build and test powerful new devices for detecting neural activity within the brain. To understand how the brain operates, we ...

Researchers Developed VO2 Based MEMS Mirror Actuator That Requires Very Low Power

A joint research by the US Air Force Research Laboratory Sensors Directorate and Michigan State University have developed micro-electromechanical systems (MEMS) actuator based on smart materials, specifically vanadium dioxide (VO2). In the room temperature, Vanadium dioxide exhibits the Mott transition. It is a not-well-understood phenomenon known to occur in transition metal chalcogenides and transition me ...

Flat microscope for the brain could help restore lost eyesight

HOUSTON – (July 12, 2017) – Rice University engineers are building a flat microscope, called FlatScope TM, and developing software that can decode and trigger neurons on the surface of the brain. Their goal as part of a new government initiative is to provide an alternate path for sight and sound to be delivered directly to the brain. The project is part of a $65 million effort announced this week by the fe ...

L BAND SATELLITE ANTENNAS REVEALED

[SignalsEverywhere] has a lot of satellite antennas and he’s willing to show them off — inside and out — in his latest video that you can see below. Using software-defined radio techniques, you can use these antennas to pull off weather satellite images and other space signals. A lot of these antennas are actually made for some commercial purpose like keeping ships connected to Inmarsat. In fact, the shipbo ...

A DC Motor Controller with Control Leds

It can be controlled through logic levels to set the speed and the direction of the rotation of CC brushed motors and stepper motors; outputs have LEDs indicating the rotation direction. The circuit board we are presenting this time is based on the dual-bridge driver L298N, in a traditionally mounted version in a Multiwatt container with 15 staggered pins; it has two terminal blocks for attaching to DC moto ...

3 Phase AC Motor Controller

This project made using MC3PHAC from NXP Semiconductor. The project generates 6 PWM signals for 3 Phase AC Motor controller. It’s very easy to make professional VFD combining with Intelligent Power Module (IPM) or 3 Phase IGBT/MOSFET with Gate driver. The board provides 6 PWM signals for the IPM or IGBT Inverter and also brake signal. Also this board works in stand-alone mode and doesn’t require any softwar ...

SPI Isolation Board

The isolated SPI module is designed for applications, where SPI signals need to be transferred over longer distances than usually. It is based on Linear’s LTC6820. The board is designed as two layer stack-up, with GND plane on the bottom layer and signal traces and components at the top layer. Signals and power are supplied over standard 100mil (2.54mm) pitch IDC header. Specification Dimension: 40.005 mm x ...

UNCONVENTIONAL DRONE USES GAS THRUSTERS FOR CONTROL

You’ve got to hand it to [Tom Stanton] – he really thinks outside the box. And potentially outside the atmosphere, to wit: we present his reaction control gas thruster-controlled drone. Before anyone gets too excited, [Tom] isn’t building drones for use in a vacuum, although we can certainly see a use case for such devices. This is more of a hybrid affair, with counter-rotating props mounted in a centrally ...

Color sensor achieves high dynamic range with auto exposure

The Design Idea in Figure 1 is a color detector capable of generating an RGB triplet over a high dynamic range, a useful attribute for machine vision applications. The circuit implements auto-exposure control to achieve this. Thus, RGB values for a subject are invariant over a range of light intensity. The three common-cathode RGB photodiodes (U1) are reverse‑biased and pre-charged to VR (typically 0.5V) th ...
