facetVISION: Compound Eyes for Industry and Smartphone

Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF have developed a process that makes the production of a two-millimeter flat camera possible. Similar to the eyes of insects, its lens is partitioned into 135 tiny facets. The researchers have named their mini-camera concept facetVISION, following nature’s model. This mini-camera has a thickness of only two millimeters a ...

Designing Smart Chatbot with IoT for home automation with videos (Hindi & English)

In this project, we will be using ESP8266 12e manufactured by Lolin to make a Chatbot that can control our home applications. To chat with our chatbot, we will use Facebook messenger platform. Also, we will integrate some AI into our chatbot using Chatfuel. It will then be integrated with IFTTT and Adafruit IO. Adafruit IO is linked to our ESP8266 at the hardware side. In a gist, the output pins of ESP8266 ...

How to build a plant monitor with Arduino

As a preview of his latest book, Arduino Project Handbook: 25 Practical Projects to Get You Started, Mark Geddes takes us through the project to create a simple plant monitor. In this project I’ll introduce a new type of analog sensor that detects moisture levels. You’ll set up a light and sound alarm system (an inexpensive piezo buzzer) to tell you when your plant needs watering See also: How to build a la ...

A SCRATCH BUILT VFD CLOCK WITH INNER BEAUTY

Vacuum fluorescent displays (VFDs) are one of those beautiful pieces of bygone technology that you just don’t see much of anymore. At one time they were a mainstay of consumer electronics, but today they’ve largely been replaced with cheaper and more energy efficient displays such as LEDs and LCDs. While they might be objectively better displays, we can’t help but feel a pang of regret seeing a modern kitch ...

ARDUINO CONVERTS SERIAL TO PARALLEL: THE PARALLELOSLAM

After a youth spent playing with Amigas and getting into all sorts of trouble on the school computer network, I’ve always had a soft spot in my heart for hardware from the 80s and 90s. This extends beyond computers themselves, and goes so far as to include modems, photocopiers, and even the much-maligned dot matrix printer. My partner in hacking [Cosmos2000] recently found himself with a wonderful Commodore ...

ULTRA SMALL DC-DC CONVERTER WITH INTEGRATED INDUCTOR

The XCL206 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.5mm×2.0mm, H=1.0mm). A stable power supply with an output current of 600mA is configured using only two capacitors connected externally. Operating voltage range is from 2.0V to 6.0V(XCL20xG:1.8V-6.0V). Output voltage is internally set in a range from 0.8V to 4.0V in increme ...
