hallo zusammen, zum auslesen der aktuellen uhrzeit nutze ich einen dcf77-empfänger von pollin und einen sketch von arduinoclub.de (danke dieser stelle!). der sketch ist angehängt. prinzipiell funktioniert auch alles wunderbar: - arduino uno mit externer stromversorgung, um interferenzen mit dcf77-empfänger zu verhindern - usb-verbindung zum serial-output auslesen - led leuchtet + serial output, sobald ein zeitsignal vorhanden ist nach ca. 2-3 minuten erhalte ich regelmäßig ein zeitsignal, die led leuchtet ab diesem zeitpunkt, im serial monitor erscheint die aktuelle zeit. wenn ich diese schaltung aber dann teste, ohne eine usb-verbindung herzustellen (= nur mit externer stromversorgung), erhalte ich offenbar kein signal mehr (=die led leuchtet nicht mehr), auch nach längerer zeit und mehreren versuchen nicht. kontrollversuche mit usb-verbindung funktionieren dann wieder... hat jemand eine idee, wie dieses problem zustande kommt, und wie es sich lösen lässt? vielen dank..! lg ...

(datasheet: https://www.sparkfun.com/datasheets/components/smd/adxl335.pdf) tecnica: calcolo dell'arcotangente tra x e y e uscita del valore in gradi (0-360) domande: il programma è scritto bene ed in maniera essenziale? con questo settaggio hardware e software, sto già ottenendo il massimo della risoluzione e della sensibilità possibili ? programma: ///////////////////////////////////////////////// code: [select] ///////////////// //adxl335, il programma legge gli assi x e y e restituisce l'angolo di imbardata (phi) //nota: l'adxl è montato con il piano del chip ortogonale al piano terrestre, l'imbardata è intesa considerando tale piano di riferimento. /////////////////////////////////////////////...

i wondering how many people there in new york state used ubuntu or 1 of derivatives. created poll officially supported list , recognized list ubuntu website. added other obvious reasons. if use more 1 or jump around (like do) vote on 1 use most. me xubuntu changes various reasons. kde, gnome , xubuntu not happy new releases, same goes for, example, xubuntu, kubuntu or ubuntu, etc. cool. looks 1 uses ubuntu in new york. think that, lol edit: take back, there 2 of us.

i'm new writing in arduino , trying program "ultimate robot kit blue". in uploading first motor test, error message keeps coming says: avr-g++: error: missing filename after '-o' exit status 1 error compiling. invalid library found in /users/dennisleary/documents/arduino/libraries/makeblock-libraries-master: /users/dennisleary/documents/arduino/libraries/makeblock-libraries-master invalid library found in /users/dennisleary/documents/arduino/libraries/makeblock-libraries-master: /users/dennisleary/documents/arduino/libraries/makeblock-libraries-master i've been trying robot , running quite time , appreciated! you have not installed library correctly or correct name.  however, did not post code , did not post complete message guessing.  not @ guessing.  please try again, following instructions follow. to post code and/or error messages: 1) use ctrl-t in arduino ide autoformat code. 2) paste autoformatted code between...

hi all, i have photoshop cs2 on desktop computer (xp). hard drive partitioned , have photoshop scratch disk on own partition (10gb). i have photoshop cs3 on laptop (vista premium, 2gb ram). there 1 hard drive in laptop. partitioned 3 - c drive: windows + programs, s drive: system files, x drive: recovery. my question keep scratch drive on c drive or can/should partition external hard drive (250gb) , put photoshop scratch disk on there? external drive via usb. thanks in advance. don't run scratch on external.

good morning, i'm getting started arduino , esp8266, have ambitious project i'd appreciate with. as understand it, acting wifi arduino, esp8266 module can programmed run simple code (using arduino bridge) , has single, digital i/o pin can attached sensor or button. correct? if that's case, i'd have esp8266 attached rain sensor , esp8266 attached arduino uno has relay shield attached. once there enough rain max out digital pin (i realise won't have ability set rain trigger level input digital, not analogue), esp8266 send message esp8266 equipped arduino , make activate relays in specific sequence - i.e. close set of windows? is possible? can esp8266's made communicate directly or require router? all appreciated! an esp8266 in nodemcu format has multiple pins.  can use tipping bucket digital pulses of rain quantity.  higher frequency harder rain, total counts per hour or day amount of rain. then have wifi alert phone and have pins se...

hi. i curious rules ps follows when comes merging of layers blend modes other "normal". can direct me somewhere, can find information that? searched web extensively, couldn't find anything. adobe livedocs mute that, too. for example: - blend layer 2 (hard ligth) - blend layer 1 (vivid light) - background layer (normal) --> if blend layer1+2, alter visible (flattened) on-screen-image. another example: i had layer landscape + medium-blue sky without stars. on layer had white stars on (nearly) black backdrop. used "lighten" mode fill medium-blue sky stars. later on, did trick remove black backdrop , have pixels of white stars on layer. (and no, didn't "blend if" or "color range" or therelike, used blending modes!). unfortunately can't remember how did exactly, think merged layer empty layer (i know sounds weird), possibly putting both layers group first , merging group. fact is, after merging (of stars layer , "???...

i can't servo move on servo pin headers of ramps 1.4 using standard sweep code.  ramps 1.4 provides 4 servo headers tied pins 11, 6, 5, & 4 each power , ground (three pin header). need familiar board.  can blink pin 11 on first servo port know have right pin.  when tie led between signal , ground on port , run sweep code led glows dim should pwm.  yet when attach servo port - nothing (and yes checked polarity).  have checked power , ground pins on port , has healthy 5v.  have connected external power supply ramps 1.4 know has plenty of power.  same servos (i have tried 5) work on other arduinos.  ideas doing wrong? ramps 1.4 board should powerhouse since designed run 3d printers.

i new photoshop. applaude guys knowledge behind programs guys have obtained. question maybe insipid, please dont ridicule me. cannot seem color new image or text in photoshop. following tutorials , walk-throughs in different websites. let's see. draw huge circle on new page. click on gradient tool, , choose swatch color. now, can see different colors choose from. cannot seem able apply colors anything. tried doing text. see boxes colors, , above once select color, box should turn color. mine not, gets darker or lights. ( black, gray white) there should doing, or not doing? appreciate help, since have small start project due in week. once apply color object, turns gray or dark, or white....help please.

hello, i've question, does know why when put voltmeter probes on gnd pin , potentiometer realding goes few milivolts(the reading when electrodes in air) complete zero?   while im testing have connected should be, every voltmeter try show same things. (i'have tried 3 or 4 different multimeters, tried ac voltmeter:d). at first thought drivers somehow damaged , unlikly because motors turning. , tried using oscilloscope , got reading. (i have adjusted potenciometers, im curious why doesnt work vltmeter) oh , if knows correct vref equassion accurate, realy use one, because have seen two, 1 in howtomechatrinox.com way off, , 1 allways whenever different datasheet on a4988 (i rated =v ref/(8 * r sense). did not work,  motors started shiver after set current twice high equassion said my google shoots me directly pololu site , find formula: quote current limit = vref × 2.5 this applies if have original pololu a4988 0.05Ω current sense resistors. ...

originally didn't pay attention them, knowledge increases, becoming interesting. trying resolve them myself, found bit: https://www.google.com.au/url?q=https:/ ... hvmliasg7q ok, but...... machine is: raspberry pi 2 model b rev 1.1 see errors @ initial boot systemd-(something) looking @ first link gives me interesting least. lines in red, bold white. file big, not going post all, , shall work on filtering out important stuff. going through editing out non-error lines , leaving in errors - best can do. first part irda , pihat have installed i'm guessing. next dirtybit being set - on usb drive. if says clearing bit, why keep showing? thumb drives plugged in @ boot , seldom removed. next journal size. maybe not error, left there because not getting it. next error ntp addresses have in /etc/ntp.conf file. strange says can't resolve names, because can ping addresses without errors. sep 09 08:17:06 piface ntpdate[491]: can't find host tic.ntp.tels...
