je suis à la fois content de moi et à la fois très frustré. dans un de highspeed photography, j'ai réussi à faire un montage qui tient la route et un code qui fait ce que je veux. sauf qu'il ne le fait pas quand je veux. normalement, il doit attendre un premier bruit fort pour déclencher l'appareil photo (qui est en mode bulb) le son est géré par en sensor qui me renvoie un signal digital si je dépasse un seuil réglé par un potentiomètre intégré au sensor. pas de threshold dans le code donc puis géré dans le sensor directement. au boum suivant, il doit déclencher le flash. puis après une petite pause, il doit couper l'appareil photo. seulement, avant qu'il y ait du bruit, il me déclenche le flash. ensuite l'appareil photo, ensuite il coupe l'appareil photo. mais il n'attend aucun bruit pour faire les choses, dans le mauvais ordre qui plus est (mais je n'en suis pas sur à 100% il les fait peut-être presque en même temps et le flash e...

here's situation: we're developing flash-based application now, we've been running swf. we've created our own installer application install exe file user's computer. today, i've been experimenting using air deploy application. i've installed air correctly, can change main fla file's settings publish air 1.0 file, setup of air application , installer settings, create air file , run , install application using air file. this gets weird. if run individual swf file, runs correctly. when run air application, it's if movie (swf) not "playing." seems stuck on first "frame" (even though we're not doing frame-based work... it's done external files). hope enough explanation. insight great! thanks joe More discussions in Archived Spaces adobe

bonjour à tous, j'ai un projet de création d'un robot de type line follower un peu particulier et je ne sais pas trop par où commencer. bien entendu, j'ai déjà fait des recherches sur internet et plus particulièrement sur ce forum, mais en tant que débutant il est souvent difficile de faire le tri. l'idée de base semble assez simple, un robot capable de se déplacer en suivant une ligne. en effet, ce ne sont pas les robots suiveurs de ligne qui manquent. pourtant, même avec tous les exemples disponibles je n'ai pas trouvé de solution acceptable. pourquoi ? quel est le problème ? => le robot doit suivre parfaitement sa ligne (ok, logique), mais il doit aussi rester toujours positionné de la même manière sur la ligne. en prenant le cas le plus simple (une ligne droite), il faudrait s'assurer qu'il la suive en restant toujours bien positionné dessus (parallèle). et le cas se complique bien évidemment lorsqu'il y des courbes. la première i...

okay - i'm trying bottom of this. when preview pages on local testing server, online.php file (which back-end coding display number of visitors on website) getting loads of errors; however, when uploaded _remote_ server - works fine. here online.php file: ******* <?php $ip = $_server['remote_addr']; $time = time(); $minutes = 3; $found = 0; $users = 0; $user = ""; $tmpdata = $_server['document_root']."/vonline/data"; if (!is_file("$tmpdata/online.txt")) { $s = fopen("$tmpdata/online.txt","w"); fclose($s); chmod("$tmpdata/online.txt",0666); } $f = fopen("$tmpdata/online.txt","r+"); flock($f,2); while (!feof($f)) { $user[] = chop(fgets($f,65536)); } fseek($f,0,seek_set); ftruncate($f,0); foreach ($user $line) { list($savedip,$savedtime) = split("\|",$line); if ($savedip == $ip) {$savedtime = $time;$found = 1;} if ($time < $savedtime + ($minutes * 60...

rebuscando en mi cajón mágico encontrado un ventilador de un pc de hace unos años... y se me ha ocurrido probar ponerle en la rasp para ver que tal la refrigera. el ventilador en cuestión es este: pero no se si con ese voltaje que tiene le puedo conectar sin quemar la rasp, ni se como podría conectarle, ni nada... ¿alguna indicación por favor? no podrías conectarlo directamente la fuente de alimentación de la raspi porque el ventilador es de 12 v, y la raspi funciona con 5v. quizá si lo haces funcione pero va estar muy exigido y va demandar muchísima mas corriente de la fuente por lo que se puede quemar algo. lo recomendable seria ponerle una fuente de alimentación separada de 12 v exclusiva para el ventilador, en este caso dice que necesita 0.70 (700 ma), por lo que una que soporte un poco mas, quizá 1 a, debería funcionar sin problema. respecto de las conexiones, estimo que el rojo seria positivo y negro negativo, el resto no las utilizarías, pero deberías de confirmarlo a...

salve tutti, qualcuno potrebbe indicarmi che tipo di alimentatore posso collegare alla scheda pololu-  a4988 (stepper motor driver carrier ). dal sito sono riuscito capire solo che la scheda opera con un voltaggio compreso tra gli 8 ed 35 v e che l' alimentatore deve esser collegato al gnd ed vmot . inoltre la capacità elettrica non deve superare 100µf.non se nella scelta dell' alimentatore sia da considerare il fatto che la suddetta scheda dovrà essere collegata ad arduino 1 che invece supporta voltaggi fino 31 v . in pratica tutte le volte che cerco di comprare un alimentatore mi vengono chiesti il voltaggio e l' amperaggio , ma se posso ipotizzare un voltaggio di circa 30 v non cosa dire per l' amperaggio. allego links della scheda e del motore da controllare con la suddetta scheda http://www.pololu.com/catalog/product/1182 http://www.pololu.com/catalog/product/2296 qualcuno potrebbe suggerirmi che tipo di alimentatore devo comprare? grazie =( ...

hey, ik ben eindelijk bijna klaar met de constructie van onze site, volledig in joomla opgebouwd. voorlopig staat de site offline omdat de uiteindelijke content nog moet toegevoegd worden, en de editors/authors enz er nog moeten mee leren werken. nu vraag ik mij af of het mogelijk om andere users dan de administrator toegang te verlenen tot de offline site, met een wachtwoord bijvoorbeeld, en daar aanpassingen kunnen doen, zonder dat gewone gebruikers reeds zien wat er aan het gebeuren is. ideaal zou zijn moest ik ze via een url http://onzesite.be/test kunnen laten inloggen. ik vermoed dat ik de site hiervoor online zal moeten instellen en bepaalde permissies aanpassen, maar waar? verder zou ik ook - zoals je bij een forum gemakkelijk kan instellen - editors/authors/publishers slechts toegang willen geven tot bepaalde secties of categorieën. dit mogelijk? dat zou het handigste zijn als je dat online hebt staan inderdaad. die map zou je specifiek kunnen beveiligen middels htaccess zo...

ciao, vi scrivo perché mi sta capitando una cosa che non riesco capire. praticamente nel mio codice misuro una tensione sul pin a0 (una tensione da 0 12v, in questo momento proveniente da un alimentatore ma solitamente da una o piu batterie da auto). ho usato un metodo piuttosto empirico (credo) per calcolarla e il circuito che ci va dietro sinceramente non lo ho fatto io personalmente quindi non sarei in grado di postarvelo. il problema è che la primissima lettura - arduino appena partito - è sbagliata e di molto, circa 1v7 ed è una cosa che mi da fastidio perché non comprendo.. e' vero che dopo un po' di warm up, il problema si risolve e la tensione comincia ad essere sempre più vicina alla realtà. la parte di codice che ho usato per misurare la tensione è semplicemente: code: [select]   analogreference(internal);   letto = (analogread(a0)/45.83); dove: ho usato internal perché mi è sembrato più preciso / più lineare 45.83 è perchè quando misuro quello ch...
