A duck. A cat. A rooster. Your mom.

Quick, remember those four items and hold that thought. You’re going to need a sharp memory for building and playing this sweet memory game that you can build yourself, sans Arduino. It uses a Picaxe microcontroller, ensuring a headache of assembly-based program for all involved. The outcome does sound pretty rewarding though:

MemSounds is a sound based memory game played in rounds. In the first round it plays one of 4 different sounds at random. Each sound represents a different switch in the device. After the sound is played you get a turn to copy the original sound by pressing a switch. If you get the sound right, MemSounds will play two sounds in the next round and so on. The limit is about 100 rounds.

For those of you in high school or college, I just made your day. This little device, found on Instructables, emits a 17KHz high-pitched tone that’s undetectable to most people over the age of 30. It sounds similar to a ‘mosquito’ ringtone on a cellphone and will drive your classmates and/or teacher NUTS. Just rig up the circuitry and the device will emit tones. Every 30 seconds, it pauses so people can’t figure out what’s making the noise. It’s no ArtBus, but it’s something.

Just remember: I’m not responsible for the detentions you’re about to rack up.
