This repo contains most of my NixOS configs and Nix packages. Feel free to browse around and take whatever is useful.

• My main focus is on microcontrollers (and FPGAs), e.g. toolchains for ESP32 and GD32VF103.
• I'm interested in non-x86 architectures. I have a RockPro64 and I will buy a RISC-V boards as soon as they are available at an ok-ish price point.
• This repository is a Nix flake. See bootstrap if you want to build it with an old Nix. You can always use individual files without using flakes, of course. I suggest that you enable flakes on your system because they are extremely useful - lines 4 to 8 in modules/enable-flakes.nix is all that is needed.
• WPA Enterprise with hostapd plus a small script for managing client certificates
• Firewall configuration with Shorewall.
• See modules for all the small but useful stuff.
• Start a Nix shell with all the apps: nix-shell https://github.com/BBBSnowball/nixcfg/archive/refs/heads/master.tar.gz (including nixFlakes, which is very useful for bootstrapping)

Hardware (with NixOS):

• My laptop and servers (x86_64)
• GPD Pocket
• RockPro64

Hardware (without NixOS):

• GD32VF103 (RISC-V)
• ESP32
• (nRF52) (PineTime)
• UPduino v3.0
• Raspberry Pi Pico (RP2040)
• 8051 (PineBook Pro keyboard, PinePhone keyboard) - coming soon-ish
