TinyOS Workshop

A weekend classroom kit for high-school computing teachers: a pre-built USB image running the Uxn-based M/PC environment plus a printed workbook of stack-and-symbol exercises so students learn programming concepts through a real operating system instead of a sandbox.

Target user

High-school computing teachers who want a hands-on OS lesson without setting up a full Linux lab

Features
  • Pre-flashed USB stick with the M/PC environment that runs on any school laptop
  • Printed workbook of 20+ exercises teaching stack operations, file I/O, and concatenation
  • Teacher dashboard tracking which exercises each student completed via optional sync
  • Curriculum-aligned lesson plans mapped to GCSE, A-Level, and AP Computer Science
Why now

CS curricula are scrambling for hands-on OS exposure; the HN attention to M/PC shows a working, minimal educational OS exists and could be packaged for schools without IT overhead.

Demand
2/10

M/PC only drew 26 points / 2 comments on HN and is documented on niche hobbyist sites (OSnews, xxiivv wiki); no evidence teachers are searching for concatenative-OS kits, and CS-class OS exposure is overwhelmingly served by theory PDFs and Pi/Arduino hands-on kits.M/PC - A Concatenative OS | Hacker NewsM/PC: a concatenative operating system for Varvara - OSnews

Whitespace
6/10

No direct competitor bundles a Uxn/Varvara OS image plus printed stack-and-symbol workbook; the adjacent 'hands-on computing kit' space is occupied by Raspberry Pi Student Kit and CrowPi, and the 'OS curriculum' space is saturated with TPT theory units.Complete Curriculum on Operating Systems in Computer Science & IT ... - TPTCrowPi Compact Raspberry Pi 4 3 Kit for Learning Computer Science

Monetization
3/10

TPT OS curricula and Pi kits show teachers do spend on classroom materials, but the niche 'weekend workshop on a concatenative Forth-like OS' is extremely narrow and unlikely to command premium pricing beyond enthusiast curiosity.Raspberry Pi for Schools - Learn, Dream, MakeOperating system - TPT

Longevity
4/10

CS demand for OS exposure is durable, but Uxn/Varvara/M/PC depend on the small Hundred Rabbits ecosystem; the project has hobbyist sustainability, not institutional backing, so a school-facing product carries dependency risk.XXIIVV — m pcM/PC: a concatenative operating system for Varvara

Feasibility
7/10

Pre-built bootable USB image plus a printed workbook is technically straightforward since Uxn emulator and M/PC already exist; main friction is school procurement/sales channels rather than engineering.XXIIVV — m pc
