Projects & Systems
tarcinsblue — personal Fedora Atomic image
Immutable, signed Fedora Silverblue OS image built with BlueBuild. GitOps: every change lands as a PR into a GitHub Actions pipeline emitting a Sigstore/cosign-signed image, rebased via rpm-ostree.
Multi-node Kubernetes lab on IPG
Self-hosted multi-node cluster (kind-based) with RustFS distributed storage for persistent volumes, exposed via dedicated console & API endpoints — a real running control-plane.
OmniRoute AI gateway — local + free-tier LLM routing
Self-hosted LLM gateway routing one endpoint across local LM Studio models and 90+ free cloud tiers, with stacked RTK + Headroom lossless compression that preserves the prompt cache.
KTM 1290 SAS dashboard — vehicle telemetry
Automotive reverse-engineering: read the KTM CAN bus (ECU 0x7EA) and decode TPMS at 433 MHz. Kotlin/Android dashboard fed by CAN-to-BT/USB bridges and an ESP32+MPC2515 interface.
Self-hosted Hermes agent stack
Containerized personal agent (WebUI gateway + dashboard + terminal) on IPG, fronted by oauth2-proxy, wired to an LLM gateway via MCP — scheduled jobs and a real terminal + browser.
ESP32 telemetry & smart fan controller
ESP32-S3 fan controller with a web UI — 25 kHz PWM on GPIO7, WS2812 status LED, WiFi, mDNS/CDCOnBoot. Plus a 4S3P Li-ion battery-pack engineering plan for an EV bench.
Self-hosted automation & agent layer (n8n + MCP)
Automation and agent platform hosted at n8n.tarcins.network: live status API endpoints for the Kubernetes & PostgreSQL clusters, an SSH command runner across the lab, an MCP server exposing web search, and an LLM agent that chats with the Postgres store.
Central observability — Grafana over the self-hosted stack
Central Grafana dashboard aggregating health and metrics from the Kubernetes cluster and a cloud-native, high-availability PostgreSQL (operator-managed) database — fed by the lab's live status endpoints for real-time, single-pane monitoring.
