Imagine that you wanted to take a picture of a very small object and you still need to zoom in as much as possible to get the smallest detail of the picture. If you have been at this stop before, then you obviously did not try taking the whole picture at once. You must have […]

I enjoy creating sumo robots and am constantly searching for innovative sensors and materials to improve the speed and intelligence of my robots. I discovered the RPLIDAR A1, available for $99 on DFROBOT.com. I mentioned my interest in testing the sensor, and they offered me the opportunity to test it out. Once I obtained the

Since the internet remains quite vulnerable to security breaches, new measures have been taken to ensure that users are able to safely interact and navigate it in no time. Earlier last year, a new security model called the FIDO2 WebAuthn (Web Authentication) that helps to eliminate all forms of password theft and replay attacks was developed by the big

This time I’ll show how I used an Arduino to control a relay module with eight channels. Arduino in offers several advantages such as: – Open source; – Easy programming; – You can assemble your own board; – Is supported on various forums on the Internet; – Has several “shields” (facilitates the use of it

Description The WM8232 is a 16-bit analogue front end/digitiser IC which processes and digitises the analogue output signals from CCD sensors or Contact Image Sensors (CIS) at pixel sample rates of up to 35MSPS. The device has three analogue signal processing channels each of which contains Reset Level Clamping, Correlated Double Sampling (also Sample and

Maker Alessandro Grossi sent us this great DIY build for a 3D scanner built using a laser, a DSLR, and an Arduino controller. Allesandro is a Mechanical Engineer, holding a Ph.D. in product design. His day job involves helping designers and manufacturing firms develop and optimize products by means of FEM analisys and Computational fluid
This is a Magic Band Scanner. It is inspired by the Magic Band Scanners that can be found at Walt Disney World. It is used at the entrances to all the parks and rides with the FastPass system. I designed and built this as a present for my parents. They are huge Disney fans and
One of the challenges involved in recycling plastic is determining the specific type of plastic a given item is actually made of. To keep up with demand, large scale recycling centers rely on various automated systems to separate different types of plastic from a stream of incoming material. But in less technologically advanced parts of the world,

After taking mental note of the number of surveillance cameras pointed at him while standing in line at the local Home Depot, [Mac Pierce] was inspired to create A Scanner Darkly. The art installation uses beams of light projected by mock security cameras to create a dot-matrix character display on the opposing wall, which slowly blinks out US
