Random number generator (Part 2)

Part 1, 2, 3 Here is a noisy signal sampled at 100 kHz with an Arduino UNO. The signal has 8 bits of resolution and the divider bridge of the final amplifying stage has been set so that the ADC range matches (without exceeding) the input signal range. Here is the illustration of a vector of 1024 […]

Publication of the day

Raymond McNamara from the NUI Galway committed his final year works to “Embedded Implementation of Embedded Algorithms of Power System Monitoring” Quality of AC power is definitely a contemporary problem. Many disturbances are generated by the variety of power sources including, and the list is non-exhaustive, solar power, wind power, hydroelectric power. Harmonic frequencies in the […]

Deni PETAK from the University of Electronics of Zagreb wrote this thesis which includes references to arduinoos FFT . “In this work will be implemented two versions of DFT transformation and non-recursive (FIR) filters. One version has been developed in MATLAB software tool using Simulink models and Embedded Coder package, while the other hand is written in the C / […]

PlainDSP plotter

PlainDSP plotter or From figures to pictures Thanks to a small yet powerful piece of Processing code which plugs immediately with PlainDSP library example sketches (wave plotter and spectrum plotter). More on this application on plaindsp web site

Meet us at the Gamer Assembly

HL2 group is now the team behind Arduinoos. We are very much involved in the development of local and national initiatives in the world of open data, open software and open hardware. The team co-funded QuaiLab a very active FabLab which has been selected for managing a Maker Assembly aside the now famous Gamer Assy. So, you […]

Doppler Effect

Have you ever wonder why the sound from the honk of a car changes as the car travels next to you. While in the same time, the driver of this same car swears that the sound of his honk did not change a bit while he was sitting in the car! Who is right? Well, have […]

Publication of the day

I am very glad to announce the first official publication involving the PlainDSP kit and the team behind the scene. We also congratulate Kostas and his team for designing such an awesome detector. Although PlainDSP kits can be used in the context of ludic applications, it provides all the means necessary for the design of much […]

[HOWTO] PlainDSP audio shield: M2M Communication system

The Critical Tinkers team recently achieved an amazing application based on the plaindsp kit. The M2M protocol they developed provides a smart way to send information to an Arduino board using a plaindsp audio shield from any sound emitting device (e.g. a cell phone). Next video is a teaser which demonstrates the principle of operation, as long […]
