Cross-Domain Skill Map

Skills that span multiple domains. These are the bridges worth surfacing.

Skills Present in Multiple Domains

Networking

DomainUse
HHS HackersPi-hole router, VLANs, firewall
PSBBrewery network, device connectivity
2890 ClawRobot communication, field networking

Gap: Chris is weak on networking fundamentals. Pi-hole project will expose this soon.


Home Assistant

DomainUse
HHS HackersPID dashboards, automation
PSBFermentation dashboard, TILT integration

Bridge: Both domains use HA differently — brewery for telemetry, hackers for home automation.


ESP32-S3 / Embedded

DomainUse
HHS HackersComBadge, Tricorder, PID controllers
PSBBrewery PID controllers

Bridge: Same hardware, different contexts. Chris can share learnings between brewery PID and ComBadge.


Voice AI

DomainUse
HHS HackersComBadge, Tricorder, AI Desktop Companion

Note: Not in PSB or 2890 yet, but Chris wants it everywhere.


Git / Version Control

DomainUse
HHS HackersGitea for crash-lab
2890 ClawGitea for robotics team

Bridge: Chris has two Gitea instances. Could consolidate. Also: Git workflow best practices transfer.


OpenClaw / Multi-Agent

DomainUse
HHS Hackerscrash-bot system
PSB3-agent system (thinking/gemma/business)
2890 Claw2890-bot

Bridge: Same platform, different configs. Lessons from one transfer to others.


Skills Unique to Each Domain

HHS Hackers only:

  • 3D CAD / enclosure design
  • CAN bus / automotive
  • GPU passthrough / local AI inference

PSB only:

  • Brewing chemistry
  • Toast POS operation
  • Fermentation science

2890 Claw only:

  • FRC / WPILib / Java
  • Swerve drive mechanics
  • PhotonVision / AprilTags
  • Student coaching methodology

Priority Learning Paths

Based on active projects and dependencies:

Path 1: Networking Fundamentals (URGENT)

Why: Pi-hole router project is blocked by DNS/DHCP/firewall knowledge gaps.

Step 1: DNS fundamentals (what it is, how resolution works)
Step 2: DHCP fundamentals (what it does, how addresses get assigned)
Step 3: NAT and port forwarding (how routing works)
Step 4: Firewall basics (iptables/nftables concepts)
Step 5: VLANs (network segmentation)

Path 2: Home Assistant Mastery

Why: Both brewery and home projects need HA dashboards and automation.

Step 1: Lovelace dashboard basics
Step 2: Entities and automations
Step 3: ESPHome integration
Step 4: Templating and YAML magic
Step 5: Grafana integration (for pretty charts)

Path 3: Voice AI Pipeline

Why: ComBadge and Tricorder both need this.

Step 1: Wake word / hotword detection (why it's hard)
Step 2: Speech-to-text options (on-device vs API)
Step 3: Local LLM integration (Ollama + API)
Step 4: Text-to-speech output
Step 5: Latency optimization

Top Gaps to Fill

  1. DNS + DHCP + networking basics → unblock Pi-hole router project
  2. Home Assistant YAML → unblock brewery and home projects
  3. Voice AI pipeline understanding → ComBadge/Tricorder will hit this soon
  4. Grafana → fermentation dashboard needs this
  5. Java/WPILib advanced → better coaching when students code
