How to make linear actuator matrix display?

hi, i make linear actuator matrix make animated pinhead 3d display. need tons of small pwm controlled linear actuators specify exact location of each pin. thinking of building many small coils using gauge 30 magnet wire , control pins inside pwm signals have concerns precision, power consumption , heating of approach , if coils next each other influence each others. thought of using servos expensive, noisy , take lots of space. ideas might way implement linear actuator matrix such project? thanks, jarkko quote from: jarkkol on jun 23, 2013, 03:50 pm any ideas might way implement linear actuator matrix such project? here's how implement - it's going expensive, no matter how @ (even idea expensive in terms of overall time, if not money). for every pin, use micro-servo can rotate @ least (or close to) 180 degrees. attach output shaft of micro-servo grooved wheel or pulley circumference equal 2x distance want pins able move. on each pulley, attach l...

programmare con tablet

Image
ciao tutti! ho una domanda da farvi che potrebbe sembrare ridicola, vorrei sapere se fosse possibile programmare, caricare sketch ad esempio su arduino. io ho un galaxy note 10.1 e con il cavo otg posso avere un ingresso usb. detto non ciò che non è la cosa più comoda ma se si dovessero modificare solo alcuni parametri di un arduino installato chissà dove potrebbe essere comodo...  secondo voi è possibile in qualche modo? per programmare avresti bisogno di un editor di testo (e questo c'è), di un compilatore e linker (c'è arv-gcc per linux ma andrebbe adattato per android), di un software per l'upload (ci sono app che funzionano da console seriali, ma serve un software come avrdude che giri su android). insomma, al momento... non se pò fà. vedi sotto  Arduino Forum > International > Italiano > Software (Modera...

Raspbian + Transmission = disperazione totale - Raspberry Pi Forums

Image
ciao, sono da una settimana un felice possessore di questo gioiellino chiamato raspberry . vi spiego brevemente il mio problema: - sd card 1 (8gb) : installato openelec, collegato in wifi con usb key tp-link, funziona tutto meraviglia. - sd card 2 (16gb): installato raspbian, seguito la procedura classica presente sul forum, collegato tramite ethernet (in wifi è stato piuttosto tragico, dopo 2 ore di letture su wiki e forum ho abbandonato per la disperazione) funziona egregiamente (mi aspettavo un po' più di velocità però). il problema nasce da quando ho installato transmission (demone) su raspbian. la configurazione in se è elementare, ma non riesco ad accedere dal mio pc in nessun modo. ho inserito un ip statico (quello che ho scelto per il raspberry dopo aver modificato il file relativo alla parte ethernet), la porta di ascolto (9091) e un username e password mia scelta. l'ip statico funziona, non caso, spegnendo e riaccendendo il raspberry, con il classico comando p...

Reducing the SD card clock speed - Raspberry Pi Forums

hi all. designing in raspi product , trying reduce emc emissions pi. have seen in both near , far field, there 350mhz spike in spectrum. have traced harmonic of 50mhz spi clock signal. in order reduce emissions, want decrease clock signal. in config.txt, can change init_emmc_clock down 32000000 (32mhz) no further. if set lower (for example, 31000000), pi not boot, , boot terminal displays: code: select all mmc0: timeout waiting hardware interrupt - cmd52. mmc0: reset 0x2 never completed. mmc0: reset 0x4 never completed. timeout waiting hardware interrupt - cmd52. mmc0: reset 0x2 never completed. mmc0: reset 0x4 never completed. mmc0: internal clock never stabilised. know how can decrease sd card clock speed further without causing system failure this? thanks, sounds timeout somewhere needs increased - check mmc driver code. but, may mean go out of spec , still may not work. raspberrypi

Puerto Serial: Byte 0xF8 - Raspberry Pi Forums

hola todos estoy trabajando en un proyecto de identificación por tarjetas rfid y necesito hacer uso del puerto serial propio de la raspberry pi (no usb-serial) y me encuentro con el siguiente problema: cuando abro el puerto serial (usando python como lenguaje de programación) siempre se envía el byte "0xf8". estado investigando y me encontré lo siguiente en este foro: http://www.raspberrypi.org/forums/viewt ... 8&p=293067 . lo que dice básicamente es que es un bug del kernel propio de la raspberry pi y ahí me dan una solución pero sinceramente no se como aplicarlo python. si alguien sabe como solucionar este problema por el método que sea pro favor comparta su opinión. todos la ayuda me vendría bien. gracias! publique su script en python, entonces podríamos ser capaces de ayudar. raspberrypi

Steps of Bringing VB.net over to Mono - Raspberry Pi Forums

hi, steps bringing vb.net on mono & raspberry pi have vb.net (window forms application program) , know need copy binaries vb.net program mono how binaries vb.net, googled them , can understand need binaryreader? and install mono? on windows laptop? or on raspberry pi (raspbian) connected lcd display? appreciated! thanks! benniecooper wrote: but how binaries vb.net, googled them , can understand need binaryreader? nope, that's if want write vb.net program can read binary (data) files, suspect don't need. where install mono? on windows laptop? or on raspberry pi (raspbian) connected lcd display? on raspberry pi, optionally on windows too. vb.net outputs .net "bytecode", , on windows bytecode run .net runtime (which runs on windows).

10x Speed Up after receiving an I2C Event()?

first off, have gleaned , learned forum on years lurking , searching. thank all! i have ran don't understand , can't seem find answer too, maybe searching wrong tags or phrases. arduino v1.05 ide, using ledcontrol.h & wire.h i sending i2c event master 328p uno r3. slave arduino uno r3 receives i2c event fine, calls receiveevent(int eventcode); then.. calls alarm(); fine well. alarm(); simple routine blink set of leds in pattern of 6 times, 1 second on, .5 second off. however execution speed increases dramatically or @ least appears so, code being called within receiveevent. delay(1000); = has speed of approximately 100ms, have increase delay(10000); equal 1000ms of wall clock time. delay(500); = has speed of approximately 50ms. have increase delay(5000); equal 500ms if call alarm(); outside of receiveevent(int eventcode);, becomes delay(10000); equal 10000ms of wall clock time. i've tested putting alarm(); test code in front of code: [select] switch wire.rea...

Arduino Uno with Pololu Motor shield - erratic behaviour

i have dual mc33926 shield on arduino uno. i have 2 12v windscreen wiper motors connected shield i have 2 12v batteries, 1 power arduino, other power shield when run arduino , shield without motors connected appears correct (leds on shield light correct direction etc.) when connect motors, runs ok maybe 1 or 2 cycles , erratic behaviour - 1 motor keeps running, or none run when should etc. previous posts , googling suggests noise suppression capacitors (i have installed 3 per motor) also have seen suggestions inline diode on arduino power line , cap across vin , gnd on arduino have done i have separated power sources arduino , shield. still erratic behaviour persists i have swapped out shield have - same behaviour. i have measured current drawn motors run , looks current peaks @ around 5.8 5.9 12v supply. decided try running motors @ 24v reduce current consumption, same symptoms present. has got further suggestions ? thermal cutout perhaps?  recommend...

Which bootloader is on MEGA 2560 R3?

i'm trying flash mega 2560 bootloader of mega 2560 r3. wonder bootloader is. looked in folders of arduino ide 1.0.x , v2. have mega 1280 too, comparable version board too? thanks. the reason wanted upgrade using r3 , arduino official wifi shield didn't see "sd card not present" error while regularly see mega 1280 , mega 2560. it's annoying. had remove , reinsert sd card. difficult since sd card points towards side inside project boxes. had open box this. i think "v2" in bootloader name part of stk500v2 (the updated protocol necessary larger chips) , not part of "mega 2560 rev2". the boards.txt file says bootloader install , find it: quote mega2560.name=arduino mega 2560 or mega adk mega2560.bootloader.path=stk500v2 mega2560.bootloader.file=stk500boot_v2_mega2560.hex on mac translates to: /applications/arduino 1.0.5.app/contents/resources/java/hardware/arduino/bootloaders/stk500v2/stk500boot_v2_mega2560.hex ...

Problema con relè e sensore di temperatura

ciao tutti, utilizzo arduino 2009 che gestisce un sensore di temperatura e un relè. il mio problema è che quando faccio eccitare il relè tramite arduino la tensione scende di qualche mv e la temperatura di conseguenza aumenta. c'è una soluzione questo problema? utilizzo un alimentatore 12v 0.8 a si c'è, cerca sul forum che trovi la soluzione più volte spiegata. ciao.
