Mario Candy Machine Gamifies Halloween

Picture it: Halloween, 2018. You want to go to a party or take the kids out trick-or-treating, but remember what happened last year when you weren’t there to answer the door? A pack of wild children blew their allowances on 48 rolls of the cheapest toilet paper ever printed, and it took you four full hours to get all the sodden, dew-laden wads out of your rose bushes.

Halloween is a time to fear things like hobgoblins and the possibility of The Purge becoming a thing, not sugar-fueled children who are upset that you left out a bowl of Sixlets, wax lips, and alt-flavored Tootsie Rolls. So how do you take back the night? Do what [Randall Hendrix] did: build a Super Mario-themed candy-dispensing machine.

No customer, not one tiny [Thanos] or [Tony Stark] will be able to resist the giant, blinking, green start button. Pushing it cues the music and the spinning drum, which tumbles the candy around like a clothes dryer. Gravity and chance will drop one or three pieces onto a conveyor belt that runs under Mario’s feet, but it’s up to you to press the jump button at the right time.  Otherwise, he knocks your prize back into the barrel.

There’s no micro here, just woodworking, relays, motors, a sound FX board, and the amp from an old pair of PC speakers. Mario’s candy-securing jump was originally pneumatic, but now it’s powered by a 240:1 gear motor that lifts him up with a cam. Grab a fun size Snickers and slap that break button to see this marvelous machine in action.

Concerned that they’ll play until the candy is gone? Add a sinister element like the Candy-or-Death machine we saw a few years ago.

Mechanical Marvel Trades Courage for Chocolate

When we see what [Jason Allemann] does with LEGO, we wonder why more one-offs aren’t made this way. This time he’s made a Halloween mechanical marvel that will surely scare more kids than anything else they’ll encounter on their rounds — so much so that many may even decline the chocolate it dispenses. Who wouldn’t when to get it you have to reach over an animatronic skeleton hand that may grab you while a similarly mechanized spider may lunge onto your hand.

The chocolate dispensing, the hand and the spider are all animated using four motors, a LEGO Mindstorms EV3 brick to control them, and a touch sensor. When a kid presses a pumpkin attached to the touch sensor, the next chocolate candy is lowered by gravity onto a conveyor belt and carried forward to the awaiting child. That much is automatic. At the discretion of [Jason] and his partner [Kristal], using an infrared remote control and sensor, they can activate the skeleton hand and the lunging spider at just the right moment. We’re just not sure who they’ll choose to spare. It is Halloween after all, and being scared is part of the fun, so maybe spare no one? Check out the video below and tell us if you’d prefer just the treat, or both the trick and treat.

We do have to wonder if there’s any project that can’t benefit from LEGO products, even if only at the prototype stage or to help visualize an idea. As a small sample, [Jason]’s also made a remote-controlled monowheel and an actual working printer along with a Morse key telegraph machine to send it something to print.

Candy Dispenser Riddles You This

A while ago, someone brought in a candy machine to AdaCore. Sometime after, [Fabien-Chouteau] was challenged to make it more… fun. So he decided to make it harder to receive candy — you know, to encourage knowledge growth — and discourage overeating of tasty treats.

The dispenser itself is pretty simple. It consists of a hopper containing the candies, a motor with a worm-gear for delivering said candies, and a small IR sensor that detects when you wave your hand underneath (in order to receive those sweet sweet candies).

He decided to leave the system operating as is, and only interrupt the connection to the motor feed. That way when you wave your hand underneath, you have to answer a skill testing question before you proceed…
