Laser Cutting
The hardest part of laser cutting is learning vector graphics so you can design parts. I recommend starting with Inkscape, a free vector editing software package. Here are some resources you might find useful.
Nick is an expert at vector graphics. Although his content doesn’t focus on laser cutting, this is where I learned most of what I know about Inkscape. Start with his video on designing a donut.
This is my YouTube channel where I talk about tricks with Inkscape as well as some full walkthroughs of projects. Start with my video on designing a personalized keychain.
Woodworking
Woodworking with power tools involves some pretty expensive and dangerous tools, so I highly recommend you take a class at your local makerspace or woodworking workshop before diving in. Once you’ve got a feel for safety, here are some great resources for learning woodworking.
Steve Ramsey has a huge library of educational content aimed towards the novice woodworker. Start with his build of a sturdy side table.
If you’re interested in going the unplugged and low cost route, check out Rex Krueger at Woodworking for Humans. Start with his woodworking bench build.
3D Printing
To really unlock the potential of 3D printing, you’ll want to learn some form of CAD to create models from scratch. I’ll include some links below on learning CAD. To start with, you may instead want to print models someone else has made and posted to a site like Thingiverse. Here are a couple of resources on using 3D printers.
Thomas has great videos on all components of 3D printing including: slicer settings, printer reviews, and CAD. Start with his video on 3D printing basics.
Angus seems to love geeking out about odd things like shapes of constant width. Start with his video on designing a Maker Coin in Fusion 360.
Electronics
This is a great place for everything from basic circuit building blocks like resistors and capacitors to designing custom PCBs. If you haven’t done any electronics before, start with his Electronics Basics series.
If you want to get into robotics, How To Mechatronics has tons of information on programming Arduinos for mechatronic projects. Start with his tutorial on getting started with an Arduino.
Computer Aided Design (CAD)
Fusion 360 is an incredible CAD tool that you will ultimately want to learn to use if you want to get into 3D printing or CNC equipment. Although it’s a complicated program, Product Design Online really breaks it down into understandable chunks. Start with his Fusion 360 for absolute beginners video.
Machining
Quinn has a fantastic channel full of both metal lathe and machining content. Start with her intro to vertical milling series.
