Default V8 sound effects. Yeh, I'm nuts.

Those of you who have been following my Voltsrat project already know I'm nuts, so this one should come as no surprise.

I searched the site to no avail. Maybe there's a good reason for that.

Anyway, I thought it would be fun to add some V8 noise to my little hot rod, maybe for use at an intersection, to warn a pedestrian or just for fun at a car show.

So I need simulated V8 sound that can be controlled by a potentiometer, moving from idle to full rev.

I looked at RC units for models and they run $135 and up and I don't know how well suited they'd be for a larger vehicle. More amplification and bigger speakers I would imagine.

Then there's the "Soundracer V8" that plugs into a cigarette lighter and senses alternator output (IC motor) and sends a signal to an FM station, believe it or not. Darn thing sounds pretty convincing and revs and even shifts gears and it costs $40.

Now ... I know almost nothing about electronics, but could the alternator signal be simulated somehow so a Soundracer V8 could work in an electric vehicle? I would prefer to operate it from a separate pot so it isn't tied into the accelerator. That way I could rev the "engine" when I'm sitting still.

Told you I was nuts. But just in case some electrical genius wants to humor me, tell me how I might adapt this silly thing.

Hi Fishguts
I want one as well!
But wait - I want more
I would like to be able to select a sound
V8
Gas Turbine
Steam Engine
Scary electric whine
Silly person making motor sounds with his lips
diesel
rattly old ford on its last legs!

If you can select a sound you can have a bit of fun at the lights!

There's a thread specifically about this (for ebikes, but still applies) over on Endless Sphere. I don't have a link but it shouldn't be hard to find. There are a number of solutions discussed.

Thanks for the suggestion, but I went to Endless Sphere and did a search ... a little like falling into the abyss! I didn't come up with anything like I asked about here, though. They did mention using an RC sound generator and like me, most seem to find it too pricey. There was no mention of SoundRacer.

So ... I continue my quest here.

Being a fan of old slow reving diesels I quite like the sound of this.

You might check in the land of model trains. The last few years, the local EAA chapter was helping this guy: http://www.holidayexpressridingtrain.com/ with his train setup. He's added a sound module that is adaptable, which in his case he uses for a steam loco sound and whistle/bell combo. Can't remember where he got it from, but I think his email address is on the website.

Thanks! I saw a reference to technobots.co.uk on the clip and found the sound module (makes up to a 6 cylinder diesel sound - idles and revs with input from an RC controller). Total cost with shipping about $50. A cheapy Radio Shack RC controller will work. I bookmarked the site so I can go back to it if I don't find something better.

Still ... there's gotta be a way to get a SoundRacer to work ...

Thats awesome. I'd never do it on my car, but its still a neat idea and it seems to work great. Sounds eerily like our diesel ford ranger but ours can't idle that low

I could not figure how to post an mp3 so here it is in a zip it is my EV engine starting sound ( my version on the EV is much higher resolution - I had to make it smaller to fit the forum!)

I use my own circuits to trigger many sounds check out the last pages of my thread below....
