Main Page - Firmata Système canadien de référence spatiale - Calcul inverse géodésique Démonstration en ligne News: CGVD2013 is now available! Natural Resources Canada has released the Canadian Geodetic Vertical Datum of 2013 (CGVD2013), which is now the new reference standard for heights across Canada. This new height reference system is replacing the Canadian Geodetic Vertical Datum of 1928 (CGVD28), which was adopted officially by an Order in Council in 1935. Read more Geodetic reference systems stem from the need to provide a consistent and integrated reference surface for data analysis. This site provides end-users with the geodetic data and tools they need for a range of commercial and private uses. Date modified:
Blog de Snootlab Amarino - "Android meets Arduino" - Home Weller Magnastat Autopsy and Repair » Code and Life Immediately after soldering together my USB password thingy, my solder iron, the family heirloom Weller Magnastat stopped working. Some investigation showed that the base station was providing 24V AC voltage just fine, so I decided to unassemble the handpiece to see if something could be done. Here’s what I found: It turned out my iron was salvageable; read on to learn a bit about the Magnastat and how I was able to repair mine. Magnastat basics The construction of the device is surprisingly simple (see this image): The first (blue) wire from A/C power unit goes straight to the heating element (first red wire with black tube around it). A long tube goes “out” the handle part into the iron tip, and the tip is placed at the head. Note that in my model the tip and the magnastat are one solid piece (magnastat is in the base of the tip), newer models have a separate magnastat and tip, and you can change the target temperature just by changing the magnastat part.

List of single-board computers One of the first 10 MMD-1s, a prototype unit, produced by E&L Instruments in 1976. The "dyna-micro"/"MMD-1" was the world's first true single board computer.[citation needed] The MMD-1 had all components on a single printed circuit board, including memory, I/O, user input device, and a display. List of single-board computers – computers built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer.

FreedomBox Foundation [Commande à distance] Ethernet Firmata, PHP et Jquery « Skyduino – Le DIY à la française Salut à tous ! Depuis hier je suis parti dans un truc complétement dingue ^^ Le but final est on ne peut plus classique, contrôler une led depuis une page web. alors là tout de suite, webduino, json, raw tcp, … j’ai trouvé un nombre incalculable de sketch arduino pour arriver à ce but. Mais faire un simple wrapper http ou tcp avec un client python n’est pas digne d’être réaliser par moi 8) (quoi je troll … =P). Et je me suis rappeler de firmata, le protocole universelle pour contrôler à distance un microcontrolleur via le port série. Que faire ? Mais pourquoi firmata ? Sans plus attendre le code source ! /! Mais j’allai quand même pas en resté là ! Je garantit pas que toute les fonctions du xml-rpc soit valide ! Tout ce que je sais c’est que la partie pour ce loggé, et faire allumer/éteindre une led marche ! Le zip :Google Doc Pour ceux qui ne veulent pas s’embêter à lancer un serveur wamp et préparer leur carte arduino voila ce que ça donne : L'écran de log-in Ecran principal du GUI
