Tell us about your project:

It's a catapult alarm clock! what better way to wake up than to have a catapult launch a remote control necessary to turn off the infernal buzzer blaring in your ears across the room. This project uses an Arduino uno, rtc, ir remote, dc motor, buzzer and of course a catapult made from household materials to make your mornings a little more interesting. This is my first time documenting a larger project, so hopefully, it makes sense and you learn about things besides my hatred of buzzers and desire to somehow make a servo work on the catapult.

Parts list

Arduino uno

6 aa batteries

Battery pack with jack

2 npn transistors

Diode

3 220 resistors

Piece of construction board to hold motor parts

Are there any links or files you'd like to provide that support your project? Code snips, 3d print files, etc.

code is attached as a zip file, along with a diagram of the catapult, breadboard schematic, and helpful links for the parts used

That's really cool!! Prob the only thing that would make me get out of bed! I hit the snooze button repeatedly on my phone. Def something I would buy!

Very creative and brilliant execution. Taking basic household materials and making it into something like this is ingenious. Very polished presentation too!

Could perhaps just catapult the remote's batteries to reduce the size of the catapult. Try finding a coin cell at 6am in the dark whilst bleary-eyed

Optionally catapult the remote and its batteries separately to different parts of the room for that "some assembly required" pre-breakfast experience. (Although you could probably achieve the same result in one go with stronger rubber bands in the catapult !)

Thanks!

i debated using a second arduino, but ultimately decided it was easier to connect the motor instead. I know there are some (currently still mysterious to me) ways to change timers in the code , I also tried the servotimer2 library, which usually works, but that was still conflicting.

yes! i actually wasnt thinking of his ejector bed when i made this, but that is also a good catapult driven wake up device.

Thank you, im glad you like it!

i actually dont have a youtube channel as of now, since this is my first time recording and publishing a video of myself making one of my projects. But i really enjoyed it, and appreciate your and everyone's feedback, so I'm considering making a channel and doing more videos. i will definitely let you know once i have done that so you can add it.

Nice project - I like that you used an IR remote for the interface. Good thing you used a small one .

Great concept, has that fantastic inventor-y "Wallace & Gromit"/Honey I shrunk the kids" vibe, nice one!

I added your entry video to my playlist . Do you have YouTube account so I can add it to the playlist here: https://www.youtube.com/watch?v=CFDZhLtOt5g&list=PLUqSARZt5KdEc90IqY_D4yOoR3qGEeSMC
