In this episode of The Maker Show, Bret Stateham will show you how to drive a stepper motor with an Arduino.  Stepper motors are one of the unsung heroes of the age.  Hard drives, CNC Mills, 3D Printers and more just wouldn’t exist without them.  They can do so much more than a regular DC motor, but that capability comes with a little complexity.  This video hopes to de-mystify that and show you how easy it is to get started.  The 28BYJ-48 motor used in this video are inexpensive and readily available.  You should be able to find them online for under $10.00 US and they will offer a fantastic way to get into the world of stepper motors.  Grab one and follow along! This video focuses on how to actually drive the motor with an Arduino.  To gain a better understanding of the internals of the 28BYJ-48 motors, and how the ULN2003 board is used to drive them, check out Bret’s “28BYJ-48 Stepper Motor and ULN2003 Driver Intro” video (https://aka.ms/28BYJ). Lastly, you can grab all the code, and the slides from this episode from Bret’s 28BYJ-48 GitHub Repo: https://aka.ms/28byjrepo [01:44] Hooking it all up[05:20] Wave driving[07:15] Getting the code from Gi...

Satin Midi Skirts: The Difference Between Cheap And Expensive

Have you ever wondered why designer clothing is so much more expensive than, say, something you’d buy at Topshop or H&M? Some reasons for the price discrepancy can be fairly obvious in the quality of the actual fabric or even in the way a garment is made, but do those things really add up to hundreds of dollars of a difference? We analyzed a $540 satin midi skirt from Helmut Lang and a $55 satin midi skirt from Topshop to better understand what that extra $495 gets you. One of the most noticeable differences in these two garments is the fabric itself. The Helmut Lang skirt is made from 100% double silk satin (a thicker, heavier fabric than regular satin), whereas the Topshop garment is 100% polyester satin. While some people think satin means silk, the term actually refers to a type of fabric weave. Satins can be made from silk or polyester or a combination of the two. A satin weave is created by four or more weft yarns over a warp yarn, or four warp yarns over one weft yarn. Warp threads are the vertical threads in a piece of fabric that run the entire length of a fabric bolt, while the weft threads are the cross threads. Fabrics made from 100% silk cost more per yard than ...

Get Up Close To Your Soldering With A Pi Zero Microscope

Do your Mark 1 Eyeballs no longer hold their own when it comes to fine work close up? Soldering can be a literal pain under such conditions, and even for the Elf-eyed among us, dealing with pads at a 0.4-mm pitch is probably best tackled with a little optical assistance. When the times comes for a little help, consider building a soldering microscope from a Pi Zero and a few bits and bobs from around the shop. Affordable commercial soldering scopes aren’t terribly hard to come by, but [magkopian] decided to roll his own by taking advantage of the streaming capabilities of the Raspberry Pi platform, not to mention its affordability. This is a really simple hack — nothing is 3D-printed or custom milled. The stage base is a simple aluminum project box for heat resistance and extra weight, and the arm is a cheap plastic dial caliper. The PiCam is mounted to the sliding jaw of the caliper on a scrap of plastic ruler. The lens assembly of the camera needs to be hacked a little to change the focal length to work within 10 centimeters or so; alternatively, you could splurge and get a camera module with an adjustable lens. The Pi is set up for streaming, and your work area is presented i...
