Your Halloween Costume May Be Cool, But It’s Not Laser-Cut Cardboard Vintage Airplane Cool

While others are absorbed in baseball playoffs, [Aidan] has spent his recent Octobers planning incredible Halloween costumes for his son. We don’t know what he did last year, but there’s no way it’s better than this laser-cut cardboard airplane costume.

He had a few specs in mind and started with a model of a Grumman F4F-4 Wildcat from 3D Warehouse. Using SketchUp, he simplified the model and removed the landing gear and the propeller. [Aidan] created a simpler model on top of that, and set to work changing the proportions to make it adorable and toddler-sized.

To build around his son’s proportions, he inserted a 10-inch diameter scaled tube vertically into the model and squished down the fuselage in SketchUp. The plan was to have it laser-cut by Ponoko, which meant turning the design into flat pieces for them to cut. He ended up with 58 parts, many of them mirror images due to the symmetry of his design.

When the box from Ponoko arrived, [Aidan] was giddy. He was astonished at the quality of the pieces and found the plane very satisfying to build. But, he didn’t stop there. Using LayOut, he created a custom instrument cluster with reflections and shadows. The plane also has a Wii steering wheel, a motorized propeller, and of course, decals.

Happy Birthday, Son. Here’s Your Very Own Claw Machine

mrclawIf [Will Baden] is in the running for Father of the Year, he’s a shoe-in. His son requested a robot-themed birthday party, so [Will] did what any superhero father would do and built him a toy claw machine.

[Will] harvested many of the parts from copy machines: both the 5V and 24V power supplies, the limit switches, 2/3 of the motors, and the 24V solenoid coil in the claw. The carriage is from a commercial printer. He made many of the mounts, including the ones holding the 3 stepper motors from Pololu.

A PIC16F870 is running the show. [Will] programmed it in assembly using Timer2 for stepper pulsing and RB0 interrupt to drop the claw when the button is pushed. He also added a WDT to get out of code trouble if needed. The claw’s solenoid is driven by a ULN2001A Darlington array. [Will] put a kickback diode on the coil so the pulses don’t go farther than they need to. He formed the fingers of the claw by bending pieces of brake line.
