skyone Posted April 2, 2014 Report Posted April 2, 2014 (edited) 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 328http://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=item5d3f09ef4dhttp://learn.adafruit.com/dht/overviewWT5001M02-28P Mp3 sound module http://www.aliexpress.com/item/WT5001M02-28P-MP3-Voice-Module-SD-Card-Module/2050529179.htmlhttp://www.microelectronicos.com/datasheets/WT5001.pdfLM393 Sound sensorhttp://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.l2649d. 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) Edited October 7, 2014 by skyone 3 Quote
Mpreston81 Posted April 2, 2014 Report Posted April 2, 2014 My wife works for semiconductor manufacturer right here in the states if you give me a part number/ requirements I might be able to get you something sooner. Pm me. Quote
Paquitosoler Posted April 8, 2014 Report Posted April 8, 2014 (edited) congratulations, keep your projects with interest and thank you very much because I think it is what is needed. I have made ​​the blaster video? Edited April 8, 2014 by Paquitosoler Quote
skyone Posted April 9, 2014 Author Report Posted April 9, 2014 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 Quote
Allerg3n Posted April 11, 2014 Report Posted April 11, 2014 This is awesome, sky...I used your E11 tutorial to wire up my DLT-19. Might hold off on buying an iComm to see what sort of magic you weave with this...would kill 2 birds with 1 stone for me too, since it solves the fan/mic situation in one go. Quote
toybiz[TK] Posted April 15, 2014 Report Posted April 15, 2014 (edited) Following with great interest. Anything that would be self contained in the helmet and blows air? Wow! Sign me up now! What if we have an Echo fan kit as a base since his bracket could neatly hold all the components? Thank you Skyone for your focus and ingenuity! Edited April 15, 2014 by toybiz Quote
skyone Posted April 15, 2014 Author Report Posted April 15, 2014 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.. Quote
LeMaxim[TK] Posted April 16, 2014 Report Posted April 16, 2014 I'll be following this with great interest. Exciting work. Quote
Angevine[TK] Posted April 16, 2014 Report Posted April 16, 2014 Ooh.. definitely keeping an eye on this thread.. Quote
elleerre Posted April 18, 2014 Report Posted April 18, 2014 Ciao Manuel, still interested in your work, please let me know how much is it when you've the definitive ones... Quote
skyone Posted April 20, 2014 Author Report Posted April 20, 2014 (edited) 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 Edited April 20, 2014 by skyone Quote
Paquitosoler Posted April 25, 2014 Report Posted April 25, 2014 ability to integrate with aker? Quote
skyone Posted April 26, 2014 Author Report Posted April 26, 2014 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 http://www.ebay.it/itm/181008033989?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 Quote
mjrose927[TK] Posted September 17, 2014 Report Posted September 17, 2014 Any updates on this project? Quote
Spycee[TK] Posted October 1, 2014 Report Posted October 1, 2014 I just have 2 words to describe this : AWE SOME !!! How's it going ? Quote
Sly11[Admin] Posted October 1, 2014 Report Posted October 1, 2014 Must be nice to know what you are doing with electronics, I was bamboozled just trying to hook two sets of batteries in series with switches to two fans. Sent from my iPad using Tapatalk Quote
Spycee[TK] Posted October 1, 2014 Report Posted October 1, 2014 I understand maybe 50% of what he's doing... I'll check for something like that when my helmet will be completed. Some reading ahead :-) Quote
ukswrath[Staff] Posted October 7, 2014 Report Posted October 7, 2014 I love this stuff and I'm even a bit wooed on its complexity and practicality. Yes any updates? It appears a couple of the item are no longer available. Quote
skyone Posted October 7, 2014 Author Report Posted October 7, 2014 i have all the components now, i just have to assemble them i don't like too much the microphone part, i might change something Quote
TK Goatee[TK] Posted December 15, 2014 Report Posted December 15, 2014 Here's another interested follower ;-) any updates? You did it once with the e11 blaster mod and you will do it again. We believe in you skyone :-) I'm diggin' in to this myself for weeks now. I'm stuck with the code to trigger a sound file when I end a sentence. Quote
Mutter Posted December 17, 2014 Report Posted December 17, 2014 Looking forward to see what you've made! Quote
skyone Posted December 17, 2014 Author Report Posted December 17, 2014 i had problem with microphone, i can't amplify the voice simply using the mini amplifier connected to a condenser mic, i need something more specific i ordered this module some weeks ago, let's see if it will work when delivered Quote
