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
-----------
-
by the way they look different from ebay ones
-
Looks like elvis boots...
yea, i hope they didn't use those because easier to find on ebay..

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

would be good if you added some code so you could hold the selector button down for a few seconds to start back at the beginning.
Awesome stuff !!!
i remember i tried to add this feature but i couldn't find the correct code .. :/
Hi Chivo
that's a good idea pressing the button longer to get the first sound.
I implemented this feature to switch the LED in may scope on and off with the sound selector button.
So i will implement this on my realod button. Press it short < 2 sec then reload press lond >3 Sec go to the first sound. Thanks for the idea
if you like you can share your code here to make this project go further and better

i just discovered another mp3 sound module even cheaper and smaller that might fit this project
just ordered for a test
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

Looks great, really nice photos. A one inch wide elastic band enclosing the bottom of each bell will give the joined biceps and forearms a place to hang from and help keep them tight and forward facing.

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

-
thanks to the photographer too
i am 188cm tall (about 6 feet and 2 inches)
-
even better if the bicep was connected to the forearm.
yea
i will fix that

finally i have some good pictures of my ATA armor to share here

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.------------

ability to integrate with aker?
it is too big to fit inside the helmet
in the meantime i ordered this module to amplify the microphone's gain

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?
-
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
-
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..
-
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
-
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

(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)

d. s. http://diodes.com/datasheets/PAM8403.pdfvoltage 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)

sorry but it's only italian language

benvenuto Alberto ti aspettiamo anche nel forum di legione http://forum.501italica.com/
welcome and we wait for you in the legion forum!
arduino: a cheap board for E11 blaster effects
in Electronics for Helmets / Blasters
Posted
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.
