Will you be handing out candy on Halloween? Maybe you have a party to attend or kids to take around the neighborhood and can’t be home to answer the bell. You don’t want to be The Dark House With No Candy, ’cause that’s a good way to get TP’d. We’re not exactly sure what [Ben]’s catalyst was aside from trying to avoid tempting would-be thieves with an unattended bowl on the porch. Whatever the reason, we’re happy to present Candy or Death, his gamified candy (or death)-dispensing machine.
Okay, so it only dispenses candy for now. [Ben] hasn’t quite worked the kinks out of his death ray. He designed it to sit behind a porch-facing window so it can’t be messed with. All trick-or-treaters can do is push the button and take the candy. It’s built around a cereal dispenser that’s modified to be cranked by a piece of round rod driven with a NEMA-17 stepper motor and an Arduino Uno with a motor shield. The candy slides down a length of aluminium rain gutter into a plastic stacking bin, and the whole thing is built into a nice wood frame.
A few adjustments were necessary to keep it from jamming. The dispenser’s hopper uses rubber blades to govern the flow, and he ended up removing a few and trimming the others. [Ben] has an album up of all his build pics and put his code on the gits. Stick around to see videos of the machine from the front and rear.
And that is the very best Halloween hack I’ve ever seen.
That’s just the radness. You should start the motor while the level complete song is playing.
I was thinking the same thing with the song and the motor, seems too long to wait for the candy to show up.
Absolutely this. At least just to neect the fanfare with the candy. Right now it seems like it’s not working until it later, lazily dispenses some candy.
Antone else expecting it to dispense Candy with razor blades? Poisons Apples? Or at least some sugar skulls
What about poison candy?
“cause that’s a good way to get TP’d.”
You know you watch too much porn, when you’re in a technical website and you think they’re talking about ‘Triple Penetration’. I am so so sorry.
There is always something long this line for the 2nd dispenser route.

Wow, it must be good if there are 10 comments, and not one of them is a rage-filled anti-Arduino rant.
Reminds me of this: https://www.youtube.com/watch?v=3_VaiJjhRjk?t=30s
Hmm… I’ll try embedding it.

How about making the death trigger a puff of foul-smelling vapor from a fog machine? Just add some tuna or other horrible mix of scents from FlavorArt to your propylene glycol.
Hey! I’m wanting to do something similar, and I have a model that’s basically the same as your dispenser, but wall mounted. What did you use for the axle? The hole in the fan is D-shaped, and I don’t know what would work in there. Did you dremel it out? I’m really tempted to just 3d-print a copy of what I need.
