Right from the time of industrial age, we mankind have been rapidly developing. With every progress we also pollute our environment and eventually degrading it. Now global warming is an alarming threat and even the air that we breathe are getting critical. So air quality monitoring has also started to gain importance. So in this […]

Story We (most of us) really like Arduino because it’s possible to make cheap clones, lots of libraries, examples, forum support and community out there. Outside Arduino world, I like Cypress PSoC for some of its cool features like Graphical IDE, APIs, great features and understandable documentation. I have bunch of PSoC® 4 CY8CKIT-049 4xxx

Kids just aren’t huge fans of brushing their teeth. Not only are they not huge fans, they also are pretty bad at it. Teaching a young kid to brush their teeth is really hard. I created a little contraption that not only times them to make sure they brush for an entire two minutes, but

Overview This project was done for a Friend Of a Friend. He needs to monitor water flow rate and quantity for his solar heating projects. He is mainly interested in this two inch sensor but also sent along a small plastic hose bib type similar to the Adafruit 828. Both of these sensors are turbine

I came pretty close to calling this one “Magnets, How do they work?” But I thought that might confuse more than it would amuse. All jokes aside, hall effect sensors are pretty cool, and also pretty simple to use, but there are a few types you may not know about and I figured it would

In past tutorials, we have covered temperature, color, time, direction, but never distance or proximity. I think I strayed away from this because most of the lower cost proximity sensors are pretty drop-dead-simple to use and thought it might not be that useful. But the time has come, I’m writing about some distance/proximity sensors. While

PORTLAND, Ore. — Complementary metal oxide semiconductor (CMOS) imaging chips are becoming the industry’s leader in advanced process technology — instead of the traditional leaders (processors and memory) — thanks to strong demand for CMOS imaging chips in everything from smartphones to tablets to medical equipment and automobiles. Apparently, now the innovation surpasses Moore’s Law,

Note: When referring to Arduino below, this works in the same way on the emonTx which is arduino-based. The DS18B20 is a small thermometer with a built in 12bit ADC; it can be easily connected to Arduino digital input. The sensor communicates over a one-wire bus and requires little in the way of additional components.

Proximity sensors working on an induction principle are able to detect ferrous and non-ferrous metals very reliably. For those of you, who already work in this field, there´s everything clear for you probably and you know well, that induction sensors are literally one of the keystones for an industrial automation. For all of you, who´re

John has been working to recover components from old power supplies and available trash electronics, in order to build controllers to power stepper motors and other mechanisms for the FabLab. Intro The Arduino microcontroller board is able to supply a current of 40mA from its output connections. These digital outputs are fixed at 5V “ON”
