Want to help me play a prank on someone?

Someone I have a friendly competitive relationship with has played a prank on me. It was a good prank. A funny prank. A clever prank. The details are classified. Suffice is to say that it is, in the immortal words of the poet Ice Cube, on like Donkey Kong.

I would like to know if there exists a small expendable speaker I could deploy at various locations in a room or building which will play a sound file I loaded into it. Preferably, it would have a long the battery life and be at least adequate at playing the lower frequencies of the human voice. If it’s time-delayed or remote-controlled in some way, that would be even better. But mainly, it must allow me to load a sound file, be small and low cost.

How close will you be to said speaker after you place it? Could it be bluetooth which would eliminate the need for any data storage & also make it remote controllable?

I got something like this as a promotional giveaway so it didn’t even cost me the $20 that it retails for. The speaker is only the cap so it’s pretty small in size, too.

GoGroove made a small unit with a rechargeable battery several years ago. There are newer and better units now from many manufacturers, but I’ve seen used GoGrooves on eBay and other sites for low $$$. It sounds pretty good and will run for a long time on a charge. You could create blank MP3 files and load them to the USB/SD media so the unit would be silent for variable periods.

I just looked on eBay. They are called a Sonaverse and I see a couple for $20. You could go slightly more and get a Doss or some other type of unit, I guess. I’d just hate to dispose of a better player for a prank…violates my sense of balance.

Could you show me a link? I’m seeing many items when searching for it and I’m not sure which it is. I don’t know much about speaker gear so it all looks the same to me.

From the reaction, this is mobbing, not pranking.

How about something like this?

It’s a light activated device that you can record 30s of audio onto, runs on button batteries and costs $8.39 it seems.

Oh, that’s good. Thank you.

Combining it with a programmable light and placing several of those in a location could give him the proper schizophrenic experience.

If you want to add smell to sight and sound, a coworker came up with a great one. He got one of those aerosol air fresheners that periodically shoots out a loverly scent. He hid it under another guy’s desk up and behind the middle drawer. It was literally peachy for about 4 days till he figured out where it was coming from. I thought it was classic!

How are you planning to set it off? Remote controlled or bluetooth seems to be what you’d need.

This is cheap enough to be disposable, if you have the proper location.

Or something like this.

I’d like to set it off either 1) When he’s alone, which would suggest time delay. 2) When there are a lot of people in the room, which suggests remote control.

I should mention that I don’t currently have a smartphone. It could be useful in the future but it would really be best if it didn’t require a phone to activate it.

Thanks all for your info, please keep it coming if you know of more.
