That cannon fire sounds incredible. The whole thing looks, and sounds very, very good.

Don-- good work. Its a piece of art. Something you should be VERY, VERY proud of.

 

Nice, Don!

Looks like the gun sound/flash/recoil get a bit out of sync though - perhaps you're not triggering them cleanly?

 

I noticed that earlier in the video, but I though it was me. When the firing occurs close to the camera, It looked, and sounded, right on.

 

Thanks Guys,

I am having trouble withthe sync. When I operate the TC sometimes the gun sound activates but they are no where near each other. I also have some more adjustments to make on the micro switch for the cannon. I took the model from 70 degress into 90 degrees outside. Maybe that had an effect. I know when you take your tank into the cold you should wait until the temp equalizes.

Just a few tweeks and we'll have it down.

Once again none of it would have been possible without this forum. THANKS!

Hey when can we work on the sound system?...hehehehe

 

Get a lifesize tank and Ill fly down and install it.

The sound system sounded great. What more did you want to do?

 

Hey RM,

Here is the dream sound system, http://www.youtube.com/watch?v=X1iYbN09oF0&feature=player_embedded#! However it is about $500.

The motor sounds awful but the cannon sounds fantastic and very realistic.

 

The recordings are actually taken from the few Panzers left. Suamar in France has the only running King Tiger, Germany and now the US and France have running Panther Ausf. D, and England has the only Tiger 1. Germany just refurbished a Jadgapanther and restored the 75 to firing condition. These tanks are really fun, and safe. They don't crash, or sink.

So the recording sounds fantastic and very realistic because it is a recording of a real tank?

 

Audioguru,
They are noisy beasties; lots of rattling and clanking. "Stealth" wasn't thought of until many years later.

It would be very difficult to accurately reproduce the sound of the original tank from such a small model that's already crammed with lots of stuff.

 

My little clock radio has a half-decent 3" speaker but I added my own audio amp and lots of bass boost so it plays anything extremely well when its volume control is turned down.
When the volume is turned up then the bass boost is reduced so that the amplifier does not clip.

My computer speakers have very high quality 3" speakers and reproduce the cannon sound very well.

I cannot see the size of the model tank so I don't know if a half-decent 3" speaker will fit.

 

Is your little clock radio powered by AC?

What is the voltage and power requirement of the audio amp circuit that you built?

Don is pretty limited in what he can use, as everything in his tank is battery powered. The main battery (from what I understand of it) is 7.2v.

 

My clock radio amplifier is an obsolete LM2896 bridged and bootstrapped amp that I built 35 years ago for my beach sound system.
Its output is 3.6W at clipping into 4 ohms with a 7.2V supply.

Most car radio amp ICs are bridged but don't work from a supply as low as 7.2V.

 

Oh yes I have many sound bits from the KING TIGER, TIGER 1, and can get the Abrams, Sherman, Russian T-34. Elmod uses a SD card.

There just has to be a inexpensive way to do the same thing. Here is a library of sounds for tanks http://www.el-mod.de/blaster.php?osCsid=2780c0b423f21e6c1e4e95ab272b5bdb

Thanks Guys!

So are you going to be helpful here, or just continue to be Scrooge-ish?

If you're going to take the latter course of action, I will suggest to the moderators that they boot your ass out of here yet again, and I'm sure that they will gleefully follow up on it.

You should put on your "Mr. Helpful" hat about now.

 

I am sorry.
I cannot recommend a modern medium power but low supply voltage amplifier IC when they are not made anymore.
