The amazing ST-450 board adds new features that we have been wanting in Scary Terry board for a long time!

The ST-450 provides all the functions of the standard Scary Terry board, such as the ST-425, but adds a build in audio player that can be triggered via a switch, motion sensor, or voltage source. In addition, a relay has been added to the board that can be used turn on/off other devices, such as a light, whenever the audio is playing. It even has a built in 3W amplifier, so all you need to add is a speaker, although we also included a line-out jack so that you can connect a higher powered amplifier if desired!

This circuit allows you to easily drive a servo for animating the jaw of your prop. Easily create a prop with that highly sought after animatronics effect.

Operates off of a 6 to 12VDC supply (9VDC @ 1000mA is recommended).

We have included a ULN2003 chip that allows you to drive devices such as relays, lamps, solenoids for pneumatics, etc. in sync with the sound you are playing.

Jumpers allow you to choose the Left or Right channel or both for the skull to follow. 

Two header pins are provided for easily attaching the LED Audio Eyes that come with the unit. They flash in sync with the sound you are playing. You can also set the LED Eyes to stay on all the time or have them flash with the sound!

Power LED shows you in a glance whether the circuit has power or not.

    Scary Terry Audio Servo Driver with MP3/WAV player and relay, ST-450

    First let me start with, I love this board. It's well built, functions as advertised. Very useful.With that said, the only reason I didn't give it 4 stars is the limited capabilities of the MP3 Player. There is nothing wrong with it, it functions well, just as it is described. What would make it perfect would be a method of making the MP3/WAV...audio files selectable. Being able to call a specific track number would make this perfect. Other than that limitation, this board is perfect for general animatronics. Like I said before, I love this board. I have recommended and will continue to.

    I purchased 2 of these boards to create a talking cow and horse. They are working exactly as planned. This company is a pleasure to deal with. They ship quickly and are very responsive to questions about their products.
