  • MakerLisp
    The MakerLisp Machine is a portable, modular computer system, designed to recapture the feel of classic computing, with modern hardware. The CPU is a Zilog eZ80 running at 50 MHz, which supports up to 16 MB of zero wait state RAM. The system software is 'MakerLisp', a 'Lisp on Bare Metal' system that allows direct access to system hardware, while providing the concise expressive power of a functionally complete Lisp environment. The machine is also an ideal platform for an extended CP/M. A full system configuration is pictured here, with CPU, expansion board, USB keyboard, and VGA display, in the laser-cut wood 'MakerStation' enclosure.

  • Hardware-based SSH/GPG agent
    This project allows you to use various hardware security devices to operate GPG and SSH. Instead of keeping your key on your computer and decrypting it with a passphrase when you want to use it, the key is generated and stored on the device and never reaches your computer. Read more about the design on https://github.com/romanz/trezor-agent/blob/master/doc/DESIGN.md

    Currently TREZOR One, TREZOR Model T, Keepkey, Ledger Nano S, and OnlyKey are supported.
