Arduino Projects: Wrapping Machine and Welds

This wrapping machine makes wire harness creation a breeze | Arduino Blog
Many products require the use of wire harnesses, which are essentially bundles of cabling that connect one subsystem to another, such as a car engine’s sensors to the ECU. DIY projects can also find themselves needing one, but having to manage the wiring without tangles or unwanted bends can be a challenge.
YouTuber Mr. Innovative has created a simple wire harness wrapping machine that takes the user’s choice of tape and quickly spins it around the bundle. He started by cutting out the base and fixed ring out of plywood before milling the spinning ‘C’ disk from acrylic. Once these parts were attached together and a set of bearings/pulleys were added around the moving disk, a timing belt was looped on one half to an awaiting stepper motor.

Automating precise welds with an Arduino | Arduino Blog
Welding is a skill that takes years to perfect, and yet consistently placing a TIG welder in exactly the right spot many times over is nearly impossible. To assist with this process, a few of element14 Presents host Kaleb Clark and his company’s clients had constructed two rigs using PLCs but needed another solution after losing the accompanying laptop.
The first device was a repurposed lathe that was driven by a stepper motor and gearbox assembly. Clark was able to retrofit the circuit by connecting an LCD display, rotary encoder, and a motor driver to an Arduino Uno. He also attached an optically-isolated relay for controlling when the welder should activate to begin welding the part, as well as two switches for toggling the welder’s output on or off. All of these components were then placed into a briefcase lined with foil to prevent outside interference from the TIG welder.
