There are plenty of problems that are easy for humans to solve, but are almost impossibly difficult for computers. Even though it seems that with modern computing power being what it is we should be able to solve a lot of these problems, things like identifying objects in images remains fairly difficult. Similarly, identifying specific […]

I wanted to build a Nixie clock driven by an Arduino and found a few places on the internet, but none were 100% complete to get it working from the beginning to end. I either found bad wiring diagrams, bad code in programs or bad supporting literature that really slowed down my progress, so I

For those that don’t know, Gaggia is a company that produces a line of affordable “entry-level” espresso coffee makers that offer good quality consumer espresso machines at reasonable prices. The entry level machines don’t offer fine grained control over temperature, pressure and steam which is where the Gaggiuino project comes in. The Gaggiuino project is an “after

Vishay VCNL36821S IRED Integrated Proximity Sensor is fully integrated with an infrared emitter, a photodiode for proximity measurement, and a signal processing IC in a single package with a 12-bit ADC. With a range of up to 30cm (12″), this stand-alone component simplifies the use and design-in of proximity sensors as no mechanical barriers are required to

If you would like to build the ultimate espresso machine, you might be interested in a new Arduino project for the Gaggiuino. An open-source modification for espresso machines developed by Zer0-bit and a small community of developers and makers. Check out the video below for a short overview of the current base features of the mod which has transformed $500 Gaggia

Summary Students will learn how to construct a water Level Indicator/Controller that monitors the level of the overhead tank by constructing a circuit that will notify the user via SMS if the water supply to an area/home is initiated and indicate how high the water has risen when it reaches too high or too low.
Automatic Water Level Indication via SMS alert Continue Reading
Most modern computer games have a clearly-defined end, but many classics like Pac-man and Duck Hunt can go on indefinitely, limited only by technical constraints such as memory size. One would think that the classic electronic memory game Simon should fall into that category too, but with most humans struggling even to reach level 20 it’s hard to be sure. [Michael

This project includes an analog Hall Effect sensor and an Op-Amp circuit which can be used as position or angular sensing with the benefits of no contact and wearing, high stability and wide sensing range. Two configurations of the magnet and Hall sensors are analyzed. Trimmer Potentiometer PR2 provided to adjust the offset and PR1 helps to set the

Interesting how what started as a little discussion turned out to be one great solution at MAKE 100 as founders and owners of Staudt Technologies, Katharina and Yannic share their newly discovered solution with the world. Having realized how really difficult it is to quickly find stuff in equipped handbags, backpacks, purses, etc., the couple decided to hack a solution
