A programming and electronics enthusiast created an open-source Intel 486 motherboard, the M8SBC-486, in under six months, aiming for Linux and Doom compatibility but achieving more. The project, led by Maniek86, also supports DOS, Windows 3.1, and games like Prince of Persia and Wolfenstein 3D. The board features a custom FPGA chipset, lacks non-essential functions like the secondary PIC and DMA, and has potential for further development by the community. Despite some limitations with ISA slots, the project's open-source nature invites contributions for future enhancements and custom board designs.

Developer re-enables 3D printer features that Bambu Lab disabled, firm promptly threatens legal action — OrcaSlicer-BambuLab project now shuttered

Developer re-enables 3D printer features that Bambu Lab disabled, firm promptly threatens legal action — OrcaSlicer-BambuLab project now shuttered

Developer Pawel Jarczak voluntarily shut down his "OrcaSlicer-BambuLab" project after receiving legal threats from Bambu Lab for re-enabling 3D printer features that Bambu had disabled. Bambu Lab accused Jarczak of reverse engineering their software and violating their Terms of Use. Jarczak insists he did nothing wrong as his fork of OrcaSlicer only used publicly available source code. Bambu Lab's decision to restrict access to its cloud servers impacted users' ability to control their printers and AMS settings through OrcaSlicer. Jarczak is now focusing on developing firmware for Klipper-based printers and crowdfunding the project.
