From Wikipedia “The Alan Turing Year 2012 will be a celebration of the life and scientific influence of Alan Turing on the occasion of the centenary of his birth on 23 June 1912. Turing had an important influence on computing, computer science, artificial intelligence, developmental biology, and the mathematical theory of computability and made important […]
I love it! A webcomic of romance, sarcasm, math, and language.
Previous T&T I cannot deny the fact that programming Arduino went easy when its fathers introduced the automatic reset. After building encapsulated application, who would get back to the original reset procedure? On the other hand, the auto reset is relally boaring in some applications. As soon as you plug the Arduino board onto the […]
In French ! De la même façon que nombre de fiancés rencontrent leur futur(e) à l’occasion d’un mariage, la célébration d’anniversaires est propice aux rencontres aussi imprévues que fertiles. C’est exactement ce qui s’est passé hier, à l’occasion de la célébration des 10 ans de la SPN (Seuil du Poitou Numérique). Abritée (Le mot n’est […]
Part 1, 2, 3, 4 While the principle of operation is correct, the previously described assembly has limitations. It cannot handle the full range of expected capacitance values. Not enough data points are acquired for small capacitors (pF range) and it would take ages before getting the value of large capacitors (F range). This issue can be easily bypassed […]
Arduino 1.0 has been released! I installed it and started converting my code in order to make it compatible with this new Arduino’s version. I did that automatically thanks to some quick and dirty routines written in VB.NET for converting extensions and replacing “WProgram.h” by “Arduino.h”. After that, some library codes would no longer compile, […]
Part 1, 2, 3, 4 Let’s talk about the code for a while. Here is the sequence of commands that we will execute: Charge capacitor Start discharge cycle Acquire scanned data Compute time constant Compute Capacitance Format and print result Wait for completion of discharge cycle Loop back The tirikiest part of the code is probably the calculation part […]
