I was going to say this was an expensive way of getting a whistle, but having seen the cost of steam whistles, maybe not. You may not need to use a servo / mechanical switch.. What make of RC do you have on the loco? Andy Quirot (amongst others) does a switch that connects onto a servo output of your receiver. Some receivers have outputs you can use to trigger a soundcard.
I checked out the Andy Quirot website and could not find any price for or any way of ordering the two way R//C switch.
I am very interested in stocking them.
The answer might be a simple greetings card recorder with a few simple modsView attachment 220380
Like the look of these, with a Switch (the light or coin operated ones are the cheeper) would provide the Plug In to link the wire cut off from the Coin or Light sensor to a Relay or servo switch if there is such a thing. I can think of this being just the ticket.Have found a website called Talking Products. They have a cube with the following features:
Talking Cubes are an exciting new addition to our Voice Recordable Range. Bring your craft ideas to life by recording 20 seconds of speech, music or sound effects via the built-in microphone and Speaker.
Also includes an AUDIO-IN socket to allow you to record sound directly from a CD Player, Computer, iPad or iPhone, (using a 3.5mm Phono Plug Lead bought separately).
1. Record speech, music or any sound effect
2. Built-in microphone and speaker
3. You can re-record your message as many times as you wish
4. AUX Socket, 2 pin socket to connect alternative playback switches
5. Optional accessories are available for alternative activation methods, e.g. sensor or switch
6. Includes an AUDIO-IN socket to allow you to record sound directly from a CD Player, iPad, iPhone or Computer.
7. Recording time: 20 seconds
8. Size: 35 x 35 x 35mm
Will need some surgery to fit my requirements but means I can input genuine steam whistle recordings from my PC but for about £6 they are worth a try.
Problem solved. A very helpful and responsive guy called Mike Ridley of Model Radio Workshop www.modelradioworkshop.co.uk makes just such a device and if you send him an mp3 file of the whistle of your choice he would load into the chip. For £23 the MRW63 sound store is very small, plugs into a channel on the receiver, does not need a separate power supply or any other components except for the addition of a suitable loudspeaker. Just fitted one into the side tank of my Roundhouse Lady Anne[/QUO
Cool! Can you post a video of the loco in operation?
