s-lab » Drawdio Drawdio is an Interaction Design project by Jay Silver, which augments a conventional graphite pencil, and in turn creates a musical instrument which is controlled through the stroke and gesture of the performers hands. Drawdio makes use of a graphite pencil, a 555 Timer, a couple of capacitors and resistors, a speaker and battery.

robotics | Sensore prossimità LED IR - Arduino & Processing | Output, Serial, Myport, Ricevitore, Positivo Ciao a tutti ragazzi. Dopo l'algoritmo E.R.E.R. ci siamo dedicati principalmente a semplificare il sistema di funzionamento del nostro sensore per permettere anche agli utenti meno esperti di costruire il proprio senza troppi problemi. Come di certo ricorderete il sensore di prossimità LED che ho progettato tempo fa necessitava di due resistenze e quindi vari collegamenti. Incredibile il range raggiungibile con tempi di esposizione alti. L'emettitore va connesso con il positivo (gamba lunga) alla porta 12 e il negativo al GND (a fianco). Dopo aver infilato i 4 pin nei fori corretti caricate il codice: L'algoritmo si occupa di mantenere un tempo di acquisizione fisso di 115millisecondi e di filtrare la luce ambientale dando come output la quantità di luce riflessa dall' ostacolo. Dopodichè caricare in Processing questo codice: Questo codice si occupa di rappresentare in un grafico x (tempo), y (distanza ostacolo).
Segelschiff - Modellbau-Wiki Dreimastschoner Mare Frisium unter Segeln Segelschulschiff Deutschland Ein Segelschiff ist ein Schiff, das ganz oder vornehmlich aufgrund seiner Segel durch die Kraft des Windes bewegt wird. Segelschiffe waren seit dem Altertum bis zum 19. Jahrhundert die wichtigsten Verkehrsmittel für den Transport von Gütern und Personen über längere Distanzen. Sie wurden seit dem 19. Aufbau und Klassifizierung Rahsegel, die an einer Rahe hängen und quer zur Fahrtrichtung orientiert sind, und Schratsegel, die in Richtung der Schiffslängsachse gesetzt werden. Antrieb Experimentiert wurde auch mit Flettner-Rotoren, maschinell angetriebenen senkrecht stehenden Zylindern, mit deren Hilfe die Windenergie teilweise für den Schiffsantrieb genutzt werden kann; dies sind im eigentlichen Sinne keine Segelschiffe. Historische Entwicklung Historische Entwicklung des Segelschiffes Die Entwicklung der Segelschiffe begann vermutlich in Ägypten. Die Phönizier und Griechen entwickelten ab ca. 1000 v. Seit dem 17.

J. Richard Steffy Ship Reconstruction Laboratory The Pepper Wreck The Pepper wreck was found on the Tagus River mouth, Lisbon, Portugal, in 1993, during an archaeological survey promoted by the Museu Nacional de Arqueologia, directed by Francisco Alves. Starboard garboard plank (Photo: Gui Garcia) From 1996 to 1998 it was excavated by the Instituto Português de Arqueologia / Centro Nacional de Arqueologia Náutica e Subaquática as part of the program of the Portuguese pavilion at the 1998 world exhibition EXPO'98. In 1999 and 2000 the remains of its hull were excavated by the Centro Nacional de Arqueologia Náutica e Subaquática, with the support of the Institute of Nautical Archaeology / Texas A&M University. Hull remains in 1996 (Photo: Francisco Alves, CNANS) Its excavation yielded a large collection of artifacts dated from the late 16th and early 17th centuries, and lead to the tentative identification of this shipwreck as the nau Nossa Senhora dos Mártires, wrecked on September 15 1606 on its way back from Cochin, in India.

Wlan Repeater From DD-WRT Wiki You are here: DD-WRT wiki mainpage / Linking Routers / Wlan Repeater [edit] Introduction If you got here from Google you may wish to read Linking Routers first. This mode is NOT for WIRED connections between two routers! It is a wireless connection only. This is by far the EASIEST and ONLY working solution found so far after testing on multiple units. No setup changes are required to be made to your host-router / AP although some revisions or adjustments may be desirable, as stated below. if your host AP is 192.168.1.x, then your repeater could be subnet 192.168.2.x or 192.168.69.1 or ... any other unique subnet in your network. [edit] Preparation You need to know the host router's access credentials: SSID the security settings its IP address prepare and verify the DD-WRT to be configured as a repeater Note: Make sure you are using a RECENT STABLE BUILD!!! [edit] Broadcom Considerations Note:NEVER use v24 SP1. [edit] Atheros Considerations [edit] Repeater Setup Testing Footnotes
