I would like to be able to use your project for my rifle

[longy55]

@ByPS128 Hello! I am very interested in your project because I want to add light and sound to my m41a rifle. I see that you have the arduino files, but I have not seen a wiring diagram for the electronics or the sound files. Is there a way to get them? I would like to contribute in some way monetarily for all the work you have done if I can use it for myself.

Thanks in advance!

Hey. Hey, I'm glad you're interested in the project and that you're also a fan of the cult movie Aliens ;) Yes, I have the circuit diagram. I'm currently working on it and trying to figure out how to wire it all up on the perfboard.

No need to contribute financially, I'm doing this as a bit of a hobby and to learn new things. Anyway, thanks for the offer ;)

This is the segment display that the software supposes: https://www.aliexpress.us/item/3256805033000283.html

OK thank you very much for doing it altruistically!

Thanks for the information on the electronic components, what I have searched for on Github are the diagram and the sound files, but it is probably because I have not searched for them well hehe, I am going to look at everything carefully, I don't want to be annoying either.

I couldn't find any sound files either. So I bought the game "Aliens Colonial Marines" in which I muted the music and gunfire and recorded, cleaned and edited the gun sounds in AudaCity (free). I converted them to 8bit mono 22K to get small but still good quality sound files. The size is crucial for the delay before the sound starts playing. The sounds that I missed or couldn't get clean I fished in various free sound banks and then edited again as needed. It is also essential to use the DriveSort app: https://www.anerty.net/software/file/DriveSort/

which sorts the files on the SD card so that they are physically organized in sequence. This also has a major effect on the delay before the sound starts playing.

The SD card must contain the directory "01" in the root and these files in it. it's the numbering that's important, the rest of the file name doesn't matter:

001-Shoot-95.wav 002-Shoot-95.wav 003-Shoot-95.wav 004-Shoot-95.wav 005-Shoot-95.wav 006-Shoot-95.wav 010-Cock-01-Sniper.wav 011-Cock-02.wav 012-Cock-03.wav 013-Cock-04.wav 014-Cock-05.wav 020-Empty.wav 021-Empty.wav 022-Empty.wav 023-Empty.wav 024-Empty.wav 030-MagazineEject-01.wav 031-MagazineEject-02.wav 040-MagazineLoad-01.wav 041-MagazineLoad-02.wav 042-MagazineLoad-03.wav 050-MagazineReload-01.wav 051-MagazineReload-02.wav 053-MagazineReloadCock-01.wav 054-MagazineReloadCock-02.wav 060-GranadeFire-01.wav 061-GranadeFire-02.wav 062-GranadeFire-03.wav 065-GranadeLoad-01.wav 066-GranadeExplosion-01.wav 067-GranadeExplosion-02.wav 070-Volume-01-Down.wav 071-Volume-02-Down.wav 072-Volume-03-Down.wav 073-Volume-04-Down.wav 074-Volume-05-Down.wav 080-Volume-01-Up.wav 081-Volume-02-Up.wav 082-Volume-03-Up.wav 083-Volume-04-Up.wav 084-Volume-05-Up.wav 090-CardInserted.wav 091-CardRemoved.wav 092-LowBattery.wav 093-VolumeSaved.wav 094-WeaponReady.wav 095-Click-01.wav

I have used some sounds in several forms and the application plays them randomly. So, for example, the sound of pressing a tap with an empty tray doesn't sound the same and monotonous all the time. Similarly other sounds. This makes the simulator more attractive. If you had fewer sound files, their use is defined in AppConstantes.h, for example: static const int SAMPLE_EMPTY_MAGAZINE_FIRST = 20; static const int SAMPLE_EMPTY_MAGAZINE_LAST = 24; a randomly selected file with a number from 20 to 24 is used to play the empty sound

But some sound files are not used, like WeaponReady, VolumeUp/Down, Card inserted/removed and LowBattery Maybe in future with a little bit better sound player.

It's incredible work you're doing man. I can't imagine the hours you would have had to spend to get the different sounds. I'm embarrassed to ask you for those sound files without having made any effort, that's why I didn't mind contributing even if it was to the expense of the Colonial Marines :D

[ByPS128]

I wouldn't want to violate anyone's copyright by publishing those sounds. So I'm going to have to disappoint you on this one. However, with a little determination, you can create the sounds. Look for keywords like "magazine load", "cock", etc. Then you find sounds like this: https://artlist.io/sfx/track/battle-rifles---fn-fal-cocking-gun/80693 Hope it help.

I understand perfectly, thank you very much! I'll try to get the sounds out :)

nice readme! great job, everything is understood perfectly :)
