This week I have been looking at a stepper motor driver from Trinamic and revisited some magazines from my youth.
To do some testing on a Stepper Motor evaluation kit from Trinamic, I’ve been building a test rig. The idea is that the motor will drive a slider and I’ll check the position of that to determine the repeatability of
The initial design for the Topsy Turvy Clock had all of the circuits being driven through the regulator on the microcontroller. This is a MIC5219 regulator and is rated at 500mA but also has a very low dropout voltage. The
The output of my stepper motor feeds into a gearbox which I’ve been told has a ratio of approximatly 64:1. During the research of this project I came across a discussion about why the gear ratios were not exact nice
For my clock project I needed to control the position of the hands. My options were continuously rotating servos or stepper motors. I found some small 28BYJ-48 stepper motors and gearbox with ULN2003 driver boards on the internet so I
Back in 1986 for my GCSE in “Craft Design and Technology” I had the idea of building an X-Y Plotter for my project. I recently found a couple of photos of the project so I though I’d revisit the project
The stepperhead is a sophisticated multi-mode machine made by Alan Jackson. In other words, it’s both a lathe and a milling machine but it can also perform some functions not available on either. The video below shows one of these
