Our mission
Construction tech, tested against reality.
Project Ouroboros is an independent, self-funded workshop. We build field-tested electrical and BIM calculators, publish honest tool reviews, and keep NEC code references close at hand – everything earns its keep or it gets cut.
Calculators
Field-tested calculators
Wire sizing, voltage drop, conduit fill and load math – built for the job site and checked against the real numbers, not just the textbook.

Code references
NEC code lookup hub
Fast, plain-language references to the National Electrical Code – ampacity tables, conductor sizing and the sections electricians actually reach for.

Built in the open, funded by what it makes.
New calculators, reviews and code references ship regularly. Below are the latest posts.
Free NEC calculators, honest tool reviews, and BIM workflow notes — written by Michael Meyers, who has run field workflows and coordinated models on real jobs. No vendor talking points.

Construction tech that survives a real job site
Vendor demos and benchmark theater do not survive contact with mud, inspectors, or a coordination meeting that runs long. This site is the third option: tools and notes from someone who has pulled wire, coordinated models, and shipped automation that actually stayed in production.
Start with the free calculators
Fifteen browser-only tools – NEC wire sizing, voltage drop, conduit fill, box fill, load calcs, concrete, drywall, and more. They run entirely on your phone with no signal, cite the code section behind every result, and never ask for an account. **Most used on site:** – NEC Wire Size Calculator – ampacity from Table 310.16 plus voltage-drop check
– Voltage Drop Calculator – 3% branch / 5% total per NEC 210.19(A)
– Conduit Fill Calculator – Chapter 9 Table 1 for EMT, PVC, and RMC
– Electrical Load Calculator – residential service sizing per NEC Article 220 Browse all calculators →
Honest reviews and field notes
AI tools, BIM software, clamp meters, and layout gear – tested against workflows that have to close by Friday. When something does not earn its keep, this site says so. When it does, you get the specific jobs where it wins. Read the blog for teardowns, worked examples, and coordination habits that reduced rework on real projects.
Who writes this
Written and built by Michael Meyers — fourteen years in electrical construction (apprentice, journeyman, site superintendent) and five years of electrical BIM at two top-15 electrical contractors, now working full time in construction technology. Every calculator is checked against the code section it cites, and every review comes from actual use. Full background on the about page.
