Ben Eater Review: The Cleanest Electronics Education on YouTube (Clean Score 99)

Best for: High schoolers, engineering students, hobbyists, retired EEs, and parents building a project with a teen.

Age guidance: Clean for every age. The material pays off most from about 12 and up, or younger with a parent at the bench.

What the channel is

Ben Eater makes, in his channel description’s words, “tutorial-style videos about electronics, computer architecture, networking, and various other technical subjects.” His public profile says he worked at Khan Academy from 2011 to 2018, and it shows. Each video builds one idea on the last, slowly and carefully, on a real breadboard with real chips.

The channel is known for two long series. The first builds an 8-bit computer on breadboards from basic logic chips, starting with a 555 timer clock and working up through registers, an ALU, RAM, and control logic. The second builds a 6502 computer, the processor family behind the Apple II and Commodore 64, starting from “Hello, world” and going on to run Microsoft BASIC and Apple 1 software. In 2026 he started a breadboard digital clock series; part 4 was posted Oct 3, 2026.

He doesn’t upload often (134 videos since 2011), but most of them stay useful for years.

What we checked

On October 14, 2026, we pulled the captions from five videos spanning 2016 to 2026 (about 29,000 words) and searched them for profanity, sponsor reads, and political language.

Language. We found nothing: no profanity, crude humor, or even mild substitutes.

Violence and mature themes. None. The most dangerous thing on the channel is a hot soldering iron.

Politics. None found.

Sponsors. We found no third-party sponsor reads in the sampled videos. He thanks Patreon supporters, and his descriptions link to Patreon and his own store (eater.net), where he sells kits of the parts used in the videos. His store listed the complete 8-bit computer kit bundle at $329.96 (a sale price, down from $349.96) when we checked. Selling his own kits is plain and above-board, and you can follow along with parts bought anywhere.

Production and usefulness. It’s top-notch for what it is: close, steady shots of the breadboard, clear diagrams, and patient narration. We took one point off for accessibility, not quality. Videos often run close to half an hour and build on earlier ones, so a casual family viewer may get lost without starting at part 1.

Titles. They’re honest and descriptive: Making a square wave square, How do CPUs read machine code? There’s no clickbait.

Why it’s worth your time

For an EE, this is the channel you wish you’d had in college. For a teenager, it may be the clearest explanation anywhere of what a computer actually is: not magic, just clock pulses, logic gates, and bits moving across a bus. It also nods to the 1970s and 80s machines that started American personal computing. Reverse engineering Microsoft BASIC and Running Apple 1 software on a breadboard computer (Wozmon) are, in effect, hands-on computing history.

Get started with a breadboard

Ben uses (and recommends by name) the BusBoard BB830 solderless breadboard for his 8-bit computer builds. His full parts kits also come from his own shop (not an affiliate link).

FAQ

Is Ben Eater good for beginners? Yes, if they start at the beginning. Each series starts with basics like the 555 timer clock and builds step by step, but later videos assume you’ve watched the earlier ones.

Does Ben Eater sell kits? Yes. His site, eater.net, sells parts kits that match his video projects, including the 8-bit computer. The complete 8-bit bundle was listed at $329.96 on Oct 14, 2026.

Is Ben Eater family-friendly? Very. In five sampled videos (Oct 14, 2026) we found no profanity, no politics, and no third-party sponsor segments.

What is Ben Eater’s 8-bit computer? It’s a working computer built entirely on solderless breadboards from simple logic chips. It’s documented in a multi-part YouTube series covering the clock, registers, ALU, RAM, and control logic.
