Hardware covers a lot of ground: the parts inside your PC, the peripherals on your desk, and the maker world of microcontrollers, single-board computers, and 3D printers. This is the short list I keep for both sides, whether you are spec’ing out a build or wiring up your first Arduino.
PC building, reviews, and buying guides
Linus Tech Tips — The obvious starting point. Build guides, buyer’s guides, and deep dives on CPUs, motherboards, and memory, produced at a scale no one else matches. Good for figuring out what to buy and why.
Makers, electronics, and single-board computers
GreatScott! — Practical electronics, Raspberry Pi, and 3D printing projects, with a recurring “DIY or Buy” series that is genuinely useful for deciding when building something yourself is worth it.
educ8s.tv — Beginner-friendly Arduino and Raspberry Pi tutorials and projects. A gentle on-ramp if you have never touched a microcontroller.
Teaching Tech — Focused on 3D printing: beginner guides, Ender printer tips, Onshape modelling, and printer reviews. The channel to watch before and after buying your first printer.
RaspberryPiIVBeginners — Exactly what the name says: getting started with a Raspberry Pi, one small step at a time.
If you are buying, start with Linus Tech Tips. If you want to build something with your hands, GreatScott! and educ8s.tv are the friendliest places to begin.
