Don’t scrap all your costume ideas just because you don’t have access to fancy equipment. Simple stuff can do the trick sometimes, like with this Iron Man Mk 42 gauntlet by DeviantArt user Regolith247. Using a tutorial posted at The Replica Prop Forum, he started with a garden glove to make his high tech gauntlet. He also used 3mm and 5mm EVA foam, hot glue, and a few other items:
It was made using this tutorial, using a garden glove, 3mm and 5mm EVA foam, and lots of hot glue (too much, actually. Less would have made the gloves more flexible.) The gauntlet was also made from 5mm foam following this Pepakura file. Painting was done using Plasti-Dip as a primer and sealant, then it was spray painted. The palm light is a dollar store tap-light that I dissected, and then wired to the battery pack from a flashlight.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
