MOOC + Foundational Knowledge Shortlist

Goal: A vetted, tiered curriculum of free/open educational resources for Ben to build durable knowledge supporting a “mini manufacturing plant at home” — where Claude operates the digital side and Ben needs enough domain literacy to specify, evaluate, and (where unavoidable) physically execute the work.

Filter applied: structured curriculum + problem sets/projects > scattered videos. YouTube infotainment was deliberately excluded except where it functions as the official course delivery channel of an institution (e.g., MIT OCW Scholar, NPTEL).

Tier A — START HERE (the spine)

These are the 1–3 picks that anchor the curriculum. If Ben does nothing else from this list, these earn back the time.

A1. Design and Manufacturing II (2.008)

• Institution / Platform: MIT OpenCourseWare (Mech. Eng. Dept.)
• Cost: Free
• Format: Lecture notes (PDF), problem sets with solutions, design project descriptions, exam archives. Older offering — limited video, but the written materials are the gold standard.
• Time: ~10–12 weeks at 6–8 hrs/week (~75 hrs total) for the canonical pass; 30 hrs if you skim and just do the design project.
• Prereqs: High-school physics, comfort with algebra. Calculus helps but isn’t blocking.
• Why it fits: This is the single course that maps closest to “I want to operate a small-scale digital factory.” Covers process physics, equipment design, automation/control, quality, design for manufacturing, and the production system as a whole. Designed around the integration of engineering + management — exactly the COO/operator framing.
• URL: https://ocw.mit.edu/courses/2-008-design-and-manufacturing-ii-spring-2004/

A2. Manufacturing Process Technology I & II (NPTEL / IIT)

• Institution / Platform: NPTEL — IIT (Indian Institute of Technology) faculty
• Cost: Free to audit; ~$15–25 USD if Ben wants the proctored cert (he won’t need it)
• Format: ~40 video lectures + assignments per half. Structured around 12-week semesters. Notes available.
• Time: 3–5 hrs/week × 12 weeks per half, so ~80–120 hrs end-to-end. Realistic split: do MPT-I, decide if MPT-II is worth it after.
• Prereqs: None hard; physics intuition + willingness to look up unfamiliar terms.
• Why it fits: NPTEL is the most comprehensive trades-flavored engineering MOOC catalog on the planet — Indian engineering education traditionally takes manufacturing/machining seriously in a way US curricula don’t. Covers casting, forming, machining, joining, additive — the actual menu of techniques a small shop draws from.

A3. Engineering Statics — OLI (CMU Open Learning Initiative)

• Institution / Platform: Carnegie Mellon Open Learning Initiative
• Cost: Free (open & free track for independent learners)
• Format: Mastery-based interactive courseware — auto-graded problems with adaptive scaffolding. The closest thing to having a TA at your elbow.
• Time: ~40–60 hrs total; self-paced.
• Prereqs: High-school algebra & trig. Calculus not required.
• Why it fits: Statics is the load-bearing wall of all mechanical reasoning — forces, moments, stress, structural integrity. Without it, “will this fixture hold?” is a guess. OLI’s mastery format means Ben actually retains it instead of pattern-matching through problems. Best ROI per hour on this whole list.
• URL: https://oli.cmu.edu/courses/engineering-statics-open-free/

Tier B — ADJACENT FOUNDATIONS (physics / chem / math layer)

The substrate. Pick based on what feels brittle when reading Tier A material.

B1. Physics 8.01 — Classical Mechanics (MIT OCW Scholar)

• Institution / Platform: MIT OCW (Walter Lewin / Yen-Jie Lee versions)
• Cost: Free
• Format: Full video lectures, problem sets w/ solutions, exams. The OCW Scholar version is explicitly designed for self-study.
• Time: ~12 weeks × 8 hrs (~100 hrs) for the full pass; 30 hrs for a “fluency refresh.”
• Prereqs: Single-variable calculus (concurrent OK).
• Why it fits: Newtonian mechanics is the language manufacturing physics is written in. If “torque on a workpiece,” “tool deflection,” or “thermal stress” feel hand-wavy, this fixes it.
• URL: https://ocw.mit.edu/courses/8-01sc-classical-mechanics-fall-2016/

B2. Physics 8.02 — Electricity & Magnetism (MIT OCW)

• Institution / Platform: MIT OCW (Walter Lewin’s lectures are the legendary version)
• Cost: Free
• Format: 36 video lectures + problem sets + exams.
• Time: ~10 weeks × 8 hrs (~80 hrs).
• Prereqs: 8.01 + multivariable calculus (mostly applied, can fake it).
• Why it fits: Stepper motors, servos, VFDs, sensor circuits, induction heating — none of it makes sense without E&M intuition. Optional if Ben isn’t going to build or troubleshoot electronics directly; mandatory if he is.
• URL: https://ocw.mit.edu/courses/8-02-physics-ii-electricity-and-magnetism-spring-2007/

B3. General Chemistry 1 & 2 — OLI (CMU)

• Institution / Platform: CMU Open Learning Initiative
• Cost: Free (open & free track)
• Format: Interactive mastery courseware — PhET sims, virtual labs, scaffolded problems. Better than reading a textbook.
• Time: ~50 hrs per course; self-paced.
• Prereqs: High-school algebra.
• Why it fits: Materials selection (steels vs. aluminum vs. polymers), corrosion, lubricants, coolants, adhesives, finishing chemistry — these are chemistry questions in mechanics clothing. OLI’s format means Ben learns the reasoning, not the periodic table by rote.
• URL: https://oli.cmu.edu/product-category/physical-sciences-engineering-indep/

B4. OpenStax University Physics (Vols 1–3) + College Algebra/Calculus

• Institution / Platform: OpenStax (Rice University)
• Cost: Free (PDF / web / app); print ~$30 if desired
• Format: Peer-reviewed textbooks with end-of-chapter problems. Reference layer, not a course.
• Time: Reference / on-demand.
• Prereqs: Variable.
• Why it fits: When MIT OCW or NPTEL references something Ben hasn’t seen, OpenStax is the canonical free fallback. Keep the PDFs on the iPad. Don’t try to read cover-to-cover.
• URL: https://openstax.org/subjects/science

B5. Khan Academy — Calculus, Linear Algebra, Differential Equations

• Institution / Platform: Khan Academy
• Cost: Free
• Format: Short videos + adaptive practice. Best-in-class for closing specific gaps.
• Time: Ad hoc; 5–20 hrs to bridge any specific topic.
• Prereqs: None.
• Why it fits: Not a curriculum — a remediation tool. When 8.01 or Statics introduces math Ben doesn’t have, this is the fastest patch.
• URL: https://www.khanacademy.org/math

B6. Manufacturing — Open University OpenLearn

• Institution / Platform: Open University (UK) OpenLearn
• Cost: Free, CC-licensed
• Format: Short structured course (~10–15 hrs) — readings + activities. UK polytechnic flavor, very practical.
• Time: ~12 hrs total.
• Prereqs: None.
• Why it fits: A high-quality on-ramp before committing to NPTEL or 2.008. Frames manufacturing as a system (the COO lens) rather than a list of techniques.
• URL: https://www.open.edu/openlearn/science-maths-technology/design-innovation/manufacturing/content-section-0

B7. Additive Manufacturing — Open University OpenLearn

• Institution / Platform: Open University OpenLearn
• Cost: Free
• Format: Short course (~8–10 hrs) — readings, diagrams, activities.
• Time: ~10 hrs.
• Prereqs: None.
• Why it fits: If the home plant includes 3D printing (almost certainly), this is the no-fluff intro. Covers the actual process families (FDM, SLA, SLS, DMLS) and where each is appropriate.
• URL: https://www.open.edu/openlearn/science-maths-technology/additive-manufacturing/content-section-overview

Tier C — DEPTH WHEN READY (advanced / specific)

Don’t open these until Tier A is ~done. Order matters.

C1. Introduction to Manufacturing Systems (2.854)

• Institution / Platform: MIT OCW (Mech. Eng., Fall 2016)
• Cost: Free
• Format: Lecture notes, problem sets, project. Heavy on probability/queuing models.
• Time: ~80 hrs.
• Prereqs: Probability + linear algebra basics.
• Why it fits: This is the systems-level course — material flow, inventory, capacity, throughput. The mental model for “running” a plant rather than “building parts.” High leverage for the COO framing.
• URL: https://ocw.mit.edu/courses/2-854-introduction-to-manufacturing-systems-fall-2016/

C2. Control of Manufacturing Processes (2.830J)

• Institution / Platform: MIT OCW
• Cost: Free
• Format: Lecture notes + problem sets. Statistical / quality-control heavy.
• Time: ~60 hrs.
• Prereqs: Stats; ideally 2.008 first.
• Why it fits: Statistical process control, design of experiments, real-time feedback control. This is the bridge between making one part and making the same part 1,000 times — and it’s the layer Claude/AI operate at.
• URL: https://ocw.mit.edu/courses/2-830j-control-of-manufacturing-processes-sma-6303-spring-2008/

C3. Mechanics of Machining (NPTEL)

• Institution / Platform: NPTEL — IIT
• Cost: Free
• Format: Video lectures + assignments.
• Time: ~40 hrs over 8 weeks.
• Prereqs: Statics (Tier A3) helpful.
• Why it fits: Cutting forces, tool wear, chip formation, surface finish — the physics of why a CNC program produces what it produces. Skip if Ben never wants to debug a bad cut.
• URL: https://onlinecourses.nptel.ac.in/noc25_me53/preview

C4. CNC of Machine Tools and Processes (NPTEL — IIT Kharagpur)

• Institution / Platform: NPTEL
• Cost: Free
• Format: Video + notes; YouTube mirror exists.
• Time: ~40 hrs.
• Prereqs: Mechanics of Machining (C3) is the natural prequel.
• Why it fits: CNC architecture, programming logic, interpolation, post-processors. The bridge from “I bought a CNC” to “I understand what’s happening when it runs.”
• URL: https://www.classcentral.com/course/swayam-computer-numerical-control-cnc-of-machine-tools-and-processes-13953

Tier D — TRADE-SPECIFIC (the practical layer)

Honest framing: this is the tier where MOOCs are weakest. Most of what follows pairs a structured curriculum with the assumption that Ben will get hands-on time elsewhere — community college shop, makerspace, Tormach demo day, or hired-gun consultant for the first few projects.

D1. TITANS of CNC Academy

• Institution / Platform: TITANS of CNC (industry, not academic)
• Cost: Free (account required)
• Format: Structured curriculum: fixturing → live tooling → 5-axis. Heavy use of Fusion 360 CAM. Industry production-grade.
• Time: Self-paced; the “Aerospace” series alone is ~80–120 hrs of substantive work.
• Prereqs: Some CAD comfort.
• Why it fits: This is the rare free trade resource that’s not infotainment. Built by working machinists for working machinists. If Ben buys a Tormach or Haas Mini, this is the curriculum that matches the equipment.
• URL: https://academy.titansofcnc.com/

D2. Learn Fusion 360 in 30 Days (2026 Edition) — Product Design Online

• Institution / Platform: Product Design Online (Kevin Kennedy)
• Cost: Free (YouTube course with structured progression + downloadable demo files)
• Format: 30 daily lessons, ~30 min each, with project files. Updated 2026.
• Time: ~15–20 hrs.
• Prereqs: None.
• Why it fits: Fusion 360 is the practical CAD/CAM choice for a small home-mfg shop (free for personal use, integrates with TITANS curriculum, broad community). This course is the canonical structured intro — the rare YouTube-native series that earns the “course” label.
• URL: https://productdesignonline.com/learn-autodesk-fusion-360-in-30-days-official-course/

D3. Tooling U-SME — Individual Subscription (PAID, but worth it)

• Institution / Platform: SME (Society of Manufacturing Engineers)
• Cost: $79/month (3-month minimum — so ~$237 to dip in)
• Format: 600+ short structured courses across CNC, welding, metrology, materials, safety, additive. The trade industry’s training standard — what apprentices actually use.
• Time: Each class 1–2 hrs; specialty tracks 20–40 hrs.
• Prereqs: None.
• Why it fits: This is the only paid resource on the list, and it is worth the money if Ben gets serious. Tooling U is what real machinists, welders, and process techs train on. The free options are lecture-flavored; Tooling U is operator-flavored. Buy 3 months when buying first machine, run the relevant cert path, cancel.
• URL: https://www.toolingu.com/lms/order_individual

D4. Lincoln Electric Welding Education (free + paid hybrid)

• Institution / Platform: Lincoln Electric
• Cost: Free online primers; paid hands-on schools
• Format: Free reference + technique videos online. Honest signal: welding cannot be MOOC’d. Use the free material as theory; plan a 3–5 day in-person school if welding becomes load-bearing.
• Time: Variable.
• Prereqs: None.
• Why it fits: Sets accurate expectations. Welding judgment lives in your wrist, not your head.
• URL: https://education.lincolnelectric.com/

D5. Saylor Academy — ME courses (gap-filler)

• Institution / Platform: Saylor Academy
• Cost: Free; cheap proctored exam if cert wanted
• Format: Self-paced; OER textbooks + assessments.
• Time: Variable per course.
• Prereqs: Variable.
• Why it fits: Good gap-filler for specific ME subtopics (machine design, thermo, fluids) where MIT OCW feels heavy. Lower ceiling than MIT but lower friction.
• URL: https://learn.saylor.org/

Recommended path (6–12 months)

Given Ben’s actual time budget (RDCO is the day job; coursework is the side channel — realistically 4–6 hrs/week sustainable, with occasional 10-hr binges), the realistic ordering is:

Months 1–2 (foundation): Open University Manufacturing (B6, ~12 hrs) + Engineering Statics on OLI (A3, ~50 hrs). These two together give the systems lens and the load-bearing physics intuition. ~60 hrs.

Months 3–5 (core): MIT OCW 2.008 Design & Manufacturing II (A1) as the spine. Run it part-time over 3 months, ~6 hrs/week. Pull in OpenStax/Khan as needed for math gaps. ~75 hrs.

Months 6–8 (practice): Pivot to hands-on. Fusion 360 in 30 Days (D2, ~20 hrs) → TITANS of CNC Academy fundamentals (D1, ~40 hrs). Buy a 3-month Tooling U-SME subscription (D3) timed with first equipment purchase. Order at this point matters more than depth — you’re learning to operate, not derive.

Months 9–12 (depth where it pays): Choose one of NPTEL Manufacturing Process Tech (A2) or MIT 2.854 Manufacturing Systems (C1) based on which gap stings more — process knowledge or systems/throughput thinking.

Total realistic commitment: ~250–300 hrs over a year, ~5 hrs/week average. Less than half a typical undergraduate course load, but spent on the highest-leverage 20%.

Honest call-outs

• Welding cannot be MOOC’d. Period. Lincoln Electric’s free material is reference; if welding becomes critical, budget $1–3K for a 3–5 day in-person school. Same goes for grinding/finishing skill-of-hand work.
• Most “trade MOOCs” on aggregator sites (Alison, etc.) are marketing-fluff. The signal-to-noise is bad enough that I deliberately excluded them. The exceptions — TITANS of CNC, Tooling U, NPTEL, Lincoln — are the ones above.
• MIT OCW is overrated for someone whose actual goal is “operate a home shop.” It’s brilliant for understanding why things work, but if you skip A1/B1 and go straight to TITANS + Fusion + a real CNC, you’ll make parts faster. The right read is: MIT OCW builds the model that makes you a good operator and decider (and a good Claude director); TITANS builds the muscle memory that makes you a good maker. Both. In that order if time-rich, reverse if time-poor.
• Tooling U-SME at $79/mo is the only paid resource genuinely worth recommending. Pay for 3 months timed to a real project and absorb everything you can. Better ROI than any single 4-figure course.
• Don’t expect the Coursera/edX additive-manufacturing tracks to teach you a 3D printer. They’re vendor-flavored marketing wrapped in a syllabus. The OpenLearn additive course (B7) + actual time printing is the better path.
• CMU OLI is the most underrated platform on this list. Mastery-based interactive courseware that genuinely beats passive video for retention. If Ben only tries one new platform, make it this one.
