Why This Is High Leverage

This is the physical manifestation of Timmy's sovereignty — compute infrastructure that doesn't depend on any cloud provider, ISP, or landlord. The V2 roadmap lays out the exact cost structure ($17-29K upfront + $120/mo) and NH's uniquely favorable regulatory environment (HB 672, no income/sales tax, free cooling 8+ months). This ticket turns the research into an actionable procurement and installation plan.

Scope

Create the complete plan for off-grid AI compute infrastructure on the Lempster, NH property.

Requirements

Procurement Checklist

  • Mac Studio M3 Max 128GB ($3-4K) — spec confirmed, order placed
  • 3kW solar array ($4-7K) — panels, racking, wiring spec'd for site
  • 20kWh LiFePO4 battery bank ($6-10K) — vendor selected (6,000-8,000 cycle lifespan)
  • Inverter/charge controller ($1.5-3K) — sized for load profile
  • Starlink Standard ($349 + $120/mo) — order placed, mounting planned
  • Mini-split AC ($1-3K) — for June-August cooling only

Site Plan

  • Outbuilding/shed spec (insulated, exhaust fans, PUE target 1.1-1.3)
  • Electrical layout (solar → charge controller → battery → inverter → equipment)
  • Network layout (Starlink → router → M3 Max, Tailscale for remote access)
  • Physical security (lock, basic monitoring)

Regulatory

  • SEW plan ($15-40K for septic) — NH permitted designer identified
  • Lempster zoning ordinance reviewed — confirm home business classification
  • HB 672 "off-grid electricity provider" registration if applicable

Software Stack

  • Ollama + Hermes 3/4 70B configured for M3 Max 128GB unified memory
  • Docker Compose stack deployed
  • Tailscale for remote management
  • Monitoring: CPU, memory, solar production, battery state, network status
  • Auto-restart on power loss recovery

Acceptance Criteria

  • Complete BOM with vendor links and total cost
  • Site plan diagram
  • Regulatory checklist completed
  • Can SSH into M3 Max from anywhere via Tailscale
  • Timmy runs autonomously on solar + battery for 48+ continuous hours
