How to Add Power on Sound to a Console or anything

Ok so this tutorial is based around the JQ6500 MP3 sound module, it's a little pcb that does what it says, plays back mp3's!



The version I used in the video has internal flash and 5 triggers, each trigger plays back a set mp3. There a version that uses a micro SD card (JQ6500-28P)

Triggers are pulled low to activate, in the video I just tied the trigger 1 to ground so it played the first mp3 every power up.



In a PC you could install this on the power, reset, mouse button or even something like an eject button (if you rock a CD drive like I do ) (or even on the trigger ground of a 3.5mm headphone jack) All those things pull low hehe

I would recommend a diode on the trigger just to be safe however



Also in the demo I did, because I have the trigger 1 pulled low constantly, the USB driver sometimes has issues loading but in most cases (where you would permanently)do this you aren't going to be changing the sound anyhow





Also one last thing, this module runs on 3.3~5V, if you install it on a 3.3v rail, please either disconnect or use a blocking diode on the VCC pin. The usb +5v and VCC pin are common (electorally connected)





Let me know if you guys like tutorials like this

 

is it bad that my first though was to do this to booby trap things with horrible noises? like maybe making it make a screeching blown fan sound, and sneaking it into a friends computer...?

 

put it inside your friends gaming mouse and make it play sounds every time they clicks

 

Very nice. I was building a PC in an Xbox One case and was looking for something that would replicate the power and eject button noises, but all I found at the time were Nuvoton sound chips requiring a bespoke programmer which was a pain to obtain.

There seems to be quite a delay between power being applied and the Pikachu noise - is this the case or does the MP3 you used have a gap at the beginning?

 

Im assuming the N64 doesnt have a standby 5v, so the device needs to power up then play.

If doing it on a PC, you could power it on the standby voltage, then rig something up to enable the sound when the machine is actually powered up. Adds a tiny bit more complexity, but would help if thats the issue.

 

I'd be re-purposing the Xbox One Slim power supply, which I haven't got detailed information on yet, but the original one has +5Vsb. In this scenario I guess the trigger is permanently ground, so that it activates when the console is powered on, but yes, it wouldn't be too hard at all to rig up a momentary switch to the standby voltage.

 

id hook up a pull up resistor and then use a hex inverter or something on the 5v powered on line to get the low signal you want when its actually powered up.

Or something along those lines, its first thing that came to mind.

edit:

infact a transistor and couple of resistors should do it too.

 

I haven't fully looked into yet, but if the module is powered by the 5vsb line, wouldn't it be enough to simply have a momentary button bridging the connection between one of the triggers and ground to playback a file?

 

Sure, it depends how you are wiring everything up I guess to know if thats doable with the existing switch etc. I was trying to remove the need to use the switch to trigger it.

 

it has a gap and the module takes a second to boot

No the N64 doesn't have any STBV, the module runs fine on 3.3v to 5v
Tapping into the power button would work

99% sure it'll have 5VSTB, for charging the controllers and for the rest mode, where it downloads in sleep.
If you are using a Xbox one, just copy the capacitive circuit for both power and eject, on the mobo side they pull low momentarily
I don't think you'll have to worry about de-bouncing because the mp3 module handles that
