Eis algo de não muito barato, mas que vos permite controlarem os Steppers que tiram da Sucata, de 6 maneiras diferentes!
USB, TTL serial, I²C, porenciómetros, código de quadraturea, e até com consolas de Radio Controle!!! (RC)
Para os Engenhocas é algo a ter à mão, ou pelo menos, a saber que existe, para um dia que precisem...
Tic T249 USB Multi-Interface Stepper Motor Controller (Connectors Soldered)
The Tic T249 USB Multi-Interface Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using our free software. The controller supports six control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), quadrature encoder, and hobby radio control (RC). This version incorporates a Toshiba TB67S249FTG driver with innovative and unique features that include Automatic Gain Control, and it ships with soldered header pins and terminal blocks. It can operate from 10 V to 47 V and can deliver up to approximately 1.8 A per phase without a heat sink or forced air flow (or 4.5 A max with sufficient additional cooling).

3D PRINTED CNC ROUTER
Ivan Miranda
This week I started to make a CNC router with 3D printed parts and leftovers found around the shop, I know that it might seem odd that I claim that I had those guides and all lying around the shop, but the fact is that those were going to be to make a big 3D printer that is no longer an incoming project. We need to go metal!!

Spinning the wheels: Selecting a PMDC motor
Bill Marshall
My recent post Spinning the wheels: interfacing PMDC motors to a microcontroller, covered interface hardware and the use of PWM for speed control. In response to a comment from a DesignSpark member, I thought I would go through the basics of choosing a PMDC motor for a particular project. What follows is a highly simplified design process which should yield the ‘ballpark’ parameters of the motor needed.

Making A Living As A Maker: Ep. 1 Finding The Perfect Product
Artfully Rogue
I make a living as a maker and would like to share what I've learned with anyone that is trying to jump off the 9 to 5 hamster wheel and start their own maker biz.
Keep in mind, there is so much information out there in the world, my way is not the only way by any means. It's what has worked for me. Thank you for taking the time to watch my video. I am a creator of things, a metal artist, a maker of stuff, a woodworker, a welder, and a bohemian traveler of the world. I hope to inspire, motivate, teach and be a part of the lives that seek to become creators of their own wonderful creations.

Backyard Metal Casting and Homemade Forges
blkhawk
For thousands of years, man has worked metals. Although some of the technology to work metals is relatively recent, the initial human drive to create is still with us.
