Almanac

Almanac is an open-source, voice-first, privacy-first reference assistant for DIYers, homesteaders, and anyone off-grid, live at brandtweary.com/almanac. An open-weights language model and an offline library of public archives run entirely on a single 32 GB consumer GPU — no cloud, no accounts; its one optional online feature is web search. Ask a question while you're under the sink or halfway into an engine bay: it searches the collection, reads the passages that matter, and talks you through the repair by voice while your hands stay on the work.

  • Assembled and indexed an offline reference library of roughly 100,000 documents: full English Wikipedia, the complete English Project Gutenberg collection, iFixit's 103,000+ repair guides, Appropedia, and more
  • Built hybrid retrieval over the collection, combining keyword search with semantic search over document embeddings, with optional reranking of the results
  • Designed the agent loop to run in the browser: it chooses what to search and read, follows up when it needs more, and backs every answer with a linked sources list
  • Built the voice pipeline locally: faster-whisper speech-to-text and Pocket TTS synthesis
  • Protected the corpus with an RFC 6962 Merkle manifest, background scrubbing, per-document quarantine, and repair from parity or upstream copies
  • Open source under the MIT license, written in TypeScript and Python

Embedded systems

Hardware and firmware work built from stock electronics, programmed in Rust and C.

The largest is minibot, an open-source, voice-controlled robot car built February to May 2026: a Maqueen chassis driven by a BBC micro:bit, with a HuskyLens camera running custom firmware. Say "go forward" or "turn red" and it just does it, the command recognized and executed on the hardware itself with no internet involved; ask for something more involved — "patrol the room and tell me if anything gets close" — and a language model works out how to carry it out. It can also be taught: new behaviors, uploaded as scripts, persist across power cycles and run entirely on-chip.

  • Wrote the robot's firmware in embedded Rust, including a scripting engine small enough to run on the micro:bit itself, so uploaded behaviors execute on-chip at ~30 ms response with no computer attached, and a hardware watchdog that reboots the robot automatically if its firmware ever locks up
  • Implemented speech recognition that runs entirely on the camera's K210 coprocessor, recognizing roughly 50 spoken commands with no internet or server involved
  • Streamed live camera video over Bluetooth, and made the robot directly controllable by an AI agent
  • Built a working phone app that drives the robot, with the phone serving as its wireless link

Other embedded work:

  • Mushroom signal monitoring: ESP32 firmware reading microvolt-scale bioelectric signals from living Hericium erinaceus (lion's mane) mycelium through a 16-bit ADC, alongside CO2, temperature, and humidity sensing, streamed over WiFi to host servers
  • Termite vibration monitoring: a two-channel piezo rig listening for substrate vibration in a Reticulitermes-colonized log against an uncolonized control — capturing headbanging, the drumming signal termites use to communicate through the wood itself
  • Soil moisture sensing: a capacitance-based soil moisture sensor read by an ESP32 and displayed on an LCD with dry/wet calibration constants

Field Experience

Essig Museum at UC Berkeley

Worked as a full-time field technician at the Essig Museum of Entomology as part of a grant to collect DNA barcodes from every insect species in California.

  • Organized and conducted entomological surveys across California using a range of collecting techniques (pitfall, malaise, sweeping, beating)
  • Sorted, identified, and processed arthropod specimens, often preparing them for DNA barcoding and extraction
  • Secured federal and state research permits, including National Park Service permits for Point Reyes and Pinnacles and an authored research proposal for Six Rivers National Forest
  • Conducted post-construction biodiversity surveys at Apple Park under contract between Apple and the Essig Museum
  • Coordinated field operations across the UC Natural Reserve System: site scheduling, reserve invoicing, travel reporting, and budget tracking
  • Liaised with researchers and reserve managers across the state of California

Monarch Joint Venture

Full-time field technician on a statewide survey of western monarch butterflies and their habitat across California BLM land.

  • Performed vegetation and butterfly surveys across remote California public land
  • Traveled overnight to remote sites statewide to assess and evaluate habitat restoration and enhancement projects
  • Served as primary liaison with Bureau of Land Management staff
  • Communicated with and trained land managers, partners, and colleagues
  • Selected sites using ArcGIS; navigated by GPS, paper map, and compass, frequently hiking 5+ miles a day
  • Identified plants, recorded detailed field data, and maintained and repaired equipment

UC Santa Cruz, Natural Reserves

Field researcher on a project studying the effects of the 2020 California wildfire season on burned University of California reserves.

  • Served as arthropod specialist on a team conducting ecological surveys at burned and unburned habitats across six UC reserves

  • Conducted soil, vegetation, and small mammal sampling

Orana Sanctuary Biodiversity Survey

Contracted by Odonata, a bush regeneration and sustainable land management non-profit, to conduct a biodiversity survey.

  • Designed and conducted a 3-day survey assessing insect diversity at Orana Wildlife Sanctuary, collecting and identifying insects in the field
  • Liaised with conservationists, landowners, and contractors
  • Authored the full insect diversity report delivered to the client

Will Lab, UC Berkeley

Insect systematics lab under Prof. Kip Will, studying fire effects on arthropod assemblages at Mt. Diablo State Park.
