The PicoBoo is also available in a Starter Kit.
PicoBoos have become an industry standard for controlling Halloween props and have a huge number of other applications. Offering customization and reliability at an affordable price, PicoBoo controllers are an excellent go-to device for professional prop builders and beginners alike.

Programming in Real-Time

PicoBoo controllers are reliable and easy to use - no fussing around with complicated programs or code is needed. With all of our prop controllers, all you need to do is hit the record button, create your perfect sequence, then hit the record button again to save it.

Supports Audio

The PicoBoo is the most cost-effective prop controller that supports audio using a built-in flash memory sound chip that can record up to two minutes. Best of all, you can set up any audio device using the controller's audio-in and put sounds right on the sound chip. No need to do any sound format conversion or mess with computers and installing drivers.

Record up to 8 sounds - the PicoBoo will automatically select and play them them through each sequence.

Sound Amplification in a Controller

PicoBoo actually features a 30 watt internal Class D amplifier on-board so you can use smaller and easier to hide standard speakers instead of bulky powered speakers. This makes the PicoBoo an incredibly useful controller for building props with sound.

The amplifier's full output power can only be achieved with a 4 ohm speaker and a power supply of 3 amps minimum. Using a standard 1 amp power supply is still fairly loud, but at higher volume, there may be some distortion.

Relay Outputs

The PicoBoo has two 10 amp relay outputs brought out to a pluggable terminal block. The two relays give the possibility to use different voltages - rig up a light to one and use a 12 volt solenoid to the other, for example. Each relay also has both a normally-open and normally-closed contact.

You can record up to two minutes of animation at 30 FPS.

Trigger Input

The PicoBoo also has a trigger input so you can wire in the trigger of your choosing. Whether you want to use a beam sensor, infrared motion sensor, or just set up a simple button for people to push, the PicoBoo controller can be activated using a wide variety of triggers. Or, if you want the animation to go on a loop, just use a small piece of wire to connect the minus and the IN trigger pins.

Browse our selection of triggers and learn more about them right here.

Ambient and Scare Modes

When the PicoBoo isn't active and freaking out your guests, it stays in an "ambient" mode, allowing you to program a background sound to creep out your guests as they approach. Ambient mode is specifically designed for only audio programming.


We've learned the hard way how painful it is to lose your perfect program, so all of the PicoBoo controllers have a mechanism in place to make sure you don't accidentally overwrite or change your programs.

Product Faqs

Ask a Question

  • Will this controller run servos?
    This controller does not support servos. The products that do are the BooBox Flex MAX and the PicoTalk.
  • Is there a way to loop the program?
    Yes, you simply put a piece of wire into the trigger input.
  • Can I use a 12V DC 10 Amp power supply with this controller?
    Yes, as long as the power supply is 12V DC and at least 1Amp. You can never have too many amps, but never supply more voltage!
  • Do I need any type of diodes when I use solenoid valves with the PicoBoo controller?
    Generally diodes are not required. Sometimes very electrically noisy devices do require them (such as large motors). See the document Installing a DC Diode for feedback absorption for more information.
  • Will the PicoBoo control and power 24V DC devices?
    It will control them but it does not supply 24VDC power to the devices. You would need a separate 24V power supply. Click here for wiring information.
  • Can the motion sensor trigger be 5VDC or must it be 12VDC?
    Short answer: Not easily. Long answer: The controller provides 12VDC to power triggers. It will not supply 5VDC. If you need to use 5VDC you can power your motion sensor with your own 5VDC power supply or follow the instructions here to step the 12VDC voltage down to 5VDC.
  • Does the PicoBoo power supply support 220 volts 50 hz?
    Yes, the 12V power supply included with the PicoBoo controllers will run off of 220V 50hz power as well as 110V 60hz.
  • Scare sound only plays for 2 seconds
    The scare sound will only play as long as the animation. Record longer animation.
  • Can you run a 12v device and 110v device out of of the same output simultaneously?
    Absolutely not!
  • PicoBoo will not activate the 1/2" high-flow valve (or it activates it sporadically)
    If you are using the 1Amp power supply that came with the PicoBoo it is not large enough to also power the large 1/2" valve. You need to go up to a 12V 5A power supply.
  • Can these be battery powered?
    The PicoBoo and BooBox controllers can run off of a 12V battery. We recommend one with high amperage such as a car, motor cycle, or alarm system battery.
  • Is it possible to trigger this controller with a wireless remote from Home Depot?
    NO! Motions sensors from the hardware store are 120V AC and will burn up the controller. Only 12VDC trigger devices must be used with the controllers.
  • Will the ambient sound loop indefinitely until the scare sound/animation is triggered?
  • After the PicoBoo is triggered and running animation, will another trigger during the animation restart the animation?
    No, the program will run to completion.
  • Is there a way to delay the sound starting, say for a few seconds, once the trigger is activated?
    The way to do this is to record some silence into the beginning of your audio file.
  • I would like to have a 10 second pause between triggered events.
    Record the sequence on the PicoBoo but wait 10 seconds before tapping record to save. That will add 10 seconds of “post delay” during which time a sensor will not be able to activate the PicoBoo.
  • How do I make it continuously play without having to trigger it?
    Simply put a jumper (piece of wire) into the trigger input terminals and it will play the program continuously.
  • Can a reed switch be used as a trigger?
    Yes. Most reed switches are normally-closed, so depending on your application you might have to set the trigger mode on the PicoBoo to normally-closed too. Either way it will work.
  • Can I record audio into the controllers via my Android or iPhone?
  • Can I run a PicoBoo from a battery?
    Yes, you can run them from a 12V battery. More information can be found here
  • Would there be any problems if I wired one trigger to activate two PicoBoo controllers at the same time?
    That can be done by following the instructions in this document.
  • Can I have the recorded program run and repeat indefinitely without needing to be triggered each time?
