This is really cool, glad to see someone tackling this problem.<p>I have added several of my abandoned projects, here is a quick summary of them if there is any interest:<p><a href="https://github.com/satoshinm/WebSandboxMC" rel="nofollow">https://github.com/satoshinm/WebSandboxMC</a>: Bukkit plugin providing a web-based interface with an interactive WebGL 3D preview or glimpse of your server - this bundles the NetCraft frontend in a Minecraft server plugin. There are requests from Spigot users <a href="https://github.com/satoshinm/WebSandboxMC/issues/100" rel="nofollow">https://github.com/satoshinm/WebSandboxMC/issues/100</a> to make it active again, which is what inspired me to add it to Code Shelter.<p><a href="https://github.com/satoshinm/NetCraft" rel="nofollow">https://github.com/satoshinm/NetCraft</a>: Web-based fork of <a href="https://github.com/fogleman/Craft" rel="nofollow">https://github.com/fogleman/Craft</a> . Craft has been featured on Hacker News before, but it is pretty much abandoned, so I forked it into NetCraft, but then in turn ran out of time/interest to update it. The summary still applies: "Voxel game for modern web browsers (Chrome, Firefox, Safari) and desktop operating systems (Windows, macOS, Linux). Just a few thousand lines of C using modern OpenGL (shaders)." Heavily inspired by Minecraft, but much smaller and simpler.<p><a href="https://github.com/satoshinm/pill_serial" rel="nofollow">https://github.com/satoshinm/pill_serial</a>: Triple USB-to-serial adapter firmware for flashing onto an STM32F103C8T6 "blue pill" minimum development board . With this firmware you can make your own USB-to-serial adapter, times three, by flashing a <$2 blue pill board.<p><a href="https://github.com/satoshinm/pill_duck" rel="nofollow">https://github.com/satoshinm/pill_duck</a>: Scriptable USB HID device for STM32F103 blue pill (inspired by USB Rubber Ducky) . Another project for the "blue pill", this one lets you make an automated USB keyboard/mouse device, an imitation of the popular Rubber Ducky hacker tool, but a lot cheaper.<p><a href="https://github.com/satoshinm/pill_6502" rel="nofollow">https://github.com/satoshinm/pill_6502</a>: emulated 8-bit 6502 CPU and 6850 ACIA for STM32F103 blue pill . Want to build a retrocomputer but an authentic 65C02 chip is too much? Play around with a classic processor without buying old hardware? Emulate it with the cheap blue pill, with enough support at least to run the Microsoft OSI BASIC ROM.<p>I have started a few more abandoned projects on <a href="https://github.com/satoshinm?tab=repositories&type=source" rel="nofollow">https://github.com/satoshinm?tab=repositories&type=source</a> but these seem to have generated the most interest (especially the NetCraft/WebSandboxMC combination, but the pill_ projects can be quite handy), no longer can maintain them myself but would be great to see continued maintenance provided a community finds them valuable.
