Evaluation of Ovo2 by walking its AST

Major upgrades to my telescope's upper assembly - adding a Strock-style spider, filter slide system, crayford focuser, and 3D-printed 1:10 reducer

Implementing an AST printer and parser feedback loop for the Ovo2 language - creating a round-trip workflow to validate parsing correctness

A better outcome with spray silvering.

Building parser combinators in Elixir to transform token streams into an AST - implementing either/any combinators and value parsers for the Ovo2 language

Building a custom tokenizer for the Ovo2 language in Elixir - parsing strings, keywords, and pattern-matching with recursive functions

First part of my journey reimplementing Ovo2 in Elixir - from TypeScript to the BEAM, exploring language design for pure data transformations

Reflections in hindsight of this mirror.

Run DFTFringe on Mac ARM via a VM

Field testing my hyperbolized 200mm f/3.52 mirror with an MPCC corrector - achieving well-corrected large field of view with a fast mirror without a Paracorr

After some unsuccessful attempts, a first successful mirror spray silvering.
