Going Shopping
Sometimes it can be difficult to figure out where to get started on a project.1 Once you’ve read through the build instructions, you’re going to need to get your hands on some parts. I’ve provided a “shopping list” of sorts below:2
- Basic Shopping List
- 1x Arduino Uno or greater ($25)
- 1x Adafruit Motor Shield v2 ($20)
- Scavenge or Buy
- 2x NEMA-17 stepper motors ($14/each)
- 1x A to B USB cable ($4)
- 1x 9V power adapter ($7)
- Optional Parts
- 1x Micro servo motor ($6)
- 2.1mm in-line barrel jack power switch ($2.50)
- 19″ servo extension cable ($2.50)
- 10-wire rainbow ribbon cable, 15′ ($5)
- Best All-In-One-Kit
- If you want to just buy all the parts for a drawing robot in one place, you definitely want one of Sandy Noble’s Polargraph kits.
I’ve got more to say about each of these fantastic suppliers, but that is another post in and of itself. Feel free to shoot me an email or leave a comment if you just can’t wait.
