  1. in the meantime i could finally test the WT5001M02-28P sound board into a new E11 arduino set, and it's working great! it's even louder and more responsive than the old/bigger one now i have to finish to convert the code to make it compatible with this mp3 board; when ready i will share it here.
  2. i would measure with a tester the voltage output to know if a resistor is needed to fit the led spechs also pay attention on anode and cathode of led -----------
  3. by the way they look different from ebay ones http://www.ebay.it/itm/Elvis-Stormtrooper-White-Ankle-Boots-Size-9-10-/380941524148?pt=UK_Fancy_Dress_Shoes&hash=item58b1e25cb4
  4. yea, i hope they didn't use those because easier to find on ebay..
  5. thanks for sharing your code Haui, i see u used "case" syntax, i tried it before but wasn't able to make it works. Maybe i should test your code on my blaster too Snibo i sent u pm
  6. i remember i tried to add this feature but i couldn't find the correct code .. :/ if you like you can share your code here to make this project go further and better
  7. i just discovered another mp3 sound module even cheaper and smaller that might fit this project just ordered for a test http://www.aliexpress.com/item/Free-Shipping-1pc-MP3-module-U-disk-TF-card-serial-sound-card-card-reader-module/1404739474.html this module is similar to this but it's not the same, it is better because does support the serial communications with arduino it also has a LM4871 build in amplifier (3w@3ohm or 2,5w@4ohm) pdf datasheet and serial commands manual http://www.dfrobot.com/image/data/DFR0299/DFPlayer%20Mini%20Manul.pdf as stated on the manual, it is important to add a 100ohm resistor between the RX of the mp3 and TX of the arduino because of different TTL voltage (3.3 vs. 5v) edit: i also found a support page with library and code http://www.dfrobot.com/wiki/index.php/DFPlayer_Mini_SKU:DFR0299 edit2 fully tested not reliable: many problems with coding (needs its library because the serial string not only needs conversion to hexadecimal but also to calculate the checksum; the libraty code often doesn't do what requested; also, it needs to unplug power everytime the code is uploaded) audio loud but some background noise
  8. well actually they are there, but not much visible. I had a problem with the left elastic bell because the bicep touch the snap button everytime and make it release
  9. thanks to the photographer too i am 188cm tall (about 6 feet and 2 inches)
  10. finally i have some good pictures of my ATA armor to share here taken at SW Day in Rome yesterday StarWarsDay di Maurizio Valentini Photographer, su Flickr StarWarsDay di Maurizio Valentini Photographer, su Flickr StarWarsDay di Maurizio Valentini Photographer, su Flickr
  11. some more pictures of an event i may call just epic for star wars italy http://www.youtube.com/watch?v=zhNVa3OghOY
  12. it was short but amazing!! http://cinetvlandia.it/cinema/star-wars-day-italia-a-roma-nel-colosseo-foto-e-video-dellevento
  13. For the first time Disney / Lucasfilm organized in Italy an official event for the Star Wars Day Sunday, May 4th 2014 ( May the fourth ) the famous Colosseum in Rome will be surrounded by a great event. ------------
  14. it is too big to fit inside the helmet in the meantime i ordered this module to amplify the microphone's gain http://www.ebay.it/itm/181008033989?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
  15. wow great work! it is always awesome to watch a scratch build/work, in your case electronic included can u tell us what batteries are u using in your project? also i didnt see but i guess that u are using just one speaker, isn't it?
  16. i worked this days on the project, that is almos finished but now i have another problem to fix - i can't use the same microphone of the audio sensor because it hasn't enought gain - there is a background noise produced by the fans engines: EMI (Electro Magnetic Interference) so i have to: - add an external microphone with a pre-amp - probably add a capacitor to avoid the noise [edit: added 2x 1800uF 6.4v capacitors at fans terminals and noise is gone - i finally used those capacitors that a chinese seller sent me in error instead of leds that i ordered some time ago haha] actual wip
  17. thanks guys i am still waiting the delivery of the power regulator, i ordered another set from an italian shop so i hope to finish the project in the weekend to be ready for the 4th may..
  18. today i got the better Sound sensor with the analog reading of the noise the sound sensor will activate the mp3 player, giving the static burst effect when talking has stopped
  19. i am working on a new project using the arduino microcontroller to give to the stormtrooper helmet new features: - 2x fan brushless cooling blower fan with themperature sensor control - voice amplifier 3w+3w - static burst effect added at the end of talking - loop stormtroopers random talking when idle the set includes: Arduino Nano 328 http://www.ebay.it/itm/200964325858?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 DHT 11 temperature sensor http://www.ebay.it/itm/DHT11-DHT-11-Digital-Temperature-and-Humidity-Sensor-Temperature-sensor-Arduino-/400489574221?pt=LH_DefaultDomain_0&hash=item5d3f09ef4d http://learn.adafruit.com/dht/overview WT5001M02-28P Mp3 sound module http://www.aliexpress.com/item/WT5001M02-28P-MP3-Voice-Module-SD-Card-Module/2050529179.html http://www.microelectronicos.com/datasheets/WT5001.pdf LM393 Sound sensor http://www.ebay.it/itm/171219012684?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 d.s. http://www.ti.com.cn/cn/lit/ds/symlink/lm393-n.pdf (but i think this is better http://www.ebay.it/itm/161245499808?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 because support the analog reading of sound so i might change to it) 2x fans 5volts 0,10 Amp http://www.aliexpress.com/item/5015S-5V-0-1-0-3A-Black-Brushless-DC-Cooling-Blower-Fan-50x15mm-hv3n/1244855982.html 2x NPN transistors 2N2222A (40V 0,8A) http://www.ebay.it/itm/SALE-New-20-pcs-X-2N2222-2N2222A-NPN-40V-0-8A-Transistor-TO-92-/200964739171?pt=LH_DefaultDomain_0&hash=item2eca6e9063 mini amp 3w + 3w http://www.ebay.it/itm/181303482967?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 d. s. http://diodes.com/datasheets/PAM8403.pdf voltage regulator 5volts 1A http://cgi.ebay.it/ws/eBayISAPI.dll?ViewItem&item=171178535811 the power supply is based on 6xAAA rechargeable batteries (2 boxes linked in serie) for a total of 7.2v (800mAh). I prefer to have the safer nickel–metal hydride (NiMH) batteries inside the helmet rather than lithium ones. this is the actual scheme (not final and not 100% tested) the end project should include 4 small boxes: 2 batteries boxes, 1 box for arduino, 1 box for mp3/amp modules, plus microphone and themp sensor. today i had to stop the work because i realized that i need an external 5v voltage regulator to give enought power to all the components. So i must wait around a month the delivery from china of that component to start again working on it. See you on the next stage (maybe final ) in this picture u can see the themperature sensor (blue) and the fan activated by transistor and arduino the actual stage (arduino nano linked to mini-usb)
  20. you may like those screenshots from the making stage
  21. i wish to share with you this video that we at praetorian squad made to advertise our partecipation at coming event in april in Rome (Romics) sorry but it's only italian language
  22. i would go for stereo, 2 speakers is better than 1 for louder sound, you will need it during noisy exhibitions
