Retrocomputing

Restore, repair, and program vintage computers — bringing classic hardware back to life.

Restore and program vintage computers — recap a dead board and boot a machine from 1984.

Telescope Making

Make a reflecting telescope from scratch — grinding, polishing, and figuring the mirror yourself.

Grind and polish your own telescope mirror by hand, then see the sky through glass you figured.

Which is right for you?

Choose Retrocomputing if…

  • Bare-metal understanding of how computers actually work, with real nostalgia.
  • A revived machine is a tangible, usable, genuinely cool result.
  • Active communities document nearly every machine and fault.

Choose Telescope Making if…

  • A genuinely profound payoff: see the sky through optics you made by hand.
  • Meditative, low-cost craft with centuries of tradition and community behind it.
  • Teaches optics and precision you can't get from buying a scope.

Before you commit

Retrocomputing

  • Old hardware is flaky and parts can be scarce or pricey.
  • Basic soldering and patient fault-finding are part of the deal.
  • Storing machines and spares takes more space than you'd think.

Telescope Making

  • Figuring and testing a mirror is hard, slow, and unforgiving of impatience.
  • You need a dedicated grinding space and a way to test the surface.
  • It's a long arc — first light can be months of work away.
