TeleBall is a DIY Arduino based retro handheld game console that lets you play BreakOut in single-player mode using one device and Tennis for Two in multi-player mode using two devices communicating via radio. TeleBall is pretty retro and very minimalistic: it features an 8×8 pixel LED matrix display, a paddle as game controller and…
Breakout board based on the integrated 555 (SMD version), one of the integrated circuits that made the history of solid-state electronics. The 555 is a timer that can be configured in various ways incorporating a pair of comparators whose outputs are connected to the SET and RESET inputs of an RS flip-flop, so as to create…
An audio file player based on an MP3 module with FM radio, Bluetooth and remote control; a 10 V stereo output and two speakers are used for the listening. The device can even work via outlet or using two 3.7 V rechargeable lithium batteries. We all know we can find any kind of loudspeakers…
Let’s test the D7S by Omron, the world’s smallest seismic transducer, and create a seismograph capable of a sensitivity and an accuracy that are comparable to the ones found in professional tools. Each day, thousands of earthquakes occur on our planet, but most of them cannot be perceived by the population (as they…
Is a storm on its way? Let’s find out using a circuit based on a sensor to detect electrical shock in the atmosphere capable of letting us know how near and how strong it is. Meteorological centers can monitor, besides atmospheric parameters in order to estimate rain probability and volume, also storms and their…
Based on Time of Flight technology, the module provides information to a microcontroller regarding distance detected in front of its optical sensor based on time-of-flight of a light impulse. Contactless distance measurement, therefore employing electronics instruments, is a problem to which technology has been provided various solutions over the years; from a solution…
[iframe_loader src=”http://www.youtube.com/embed/beqdlg89I5o?hl=it&fs=1″ height=”349″ width=”425″ ] This module integrates the sensor MMA7455L (produced by Freescale), able to detect the movement on three axes, and then in every direction. The chip offers the possibility to select three different sensitivity (± 2g, ± 4g, ± 8g) and makes available, on an SPI bus and the I ²…
