Bunker of DOOM

Bunker of Doom is an independent, free reference site for retro-technology hobbyists, hardware hackers, and anyone interested in the electronics of the past. Its guiding idea is to bring historical technologies into present-day experiments and projects, while preserving obscure technical information for public use. The site offers extensive encyclopedic archives, manuals, catalogs, schematics, and educational material covering vacuum tubes, vintage electronics, military surplus radio, ham radio, test equipment, transformers, semiconductors, and related components.

Visitors can explore resources on classic laboratory and broadcast equipment, radios, oscilloscopes, cathode-ray tubes, Tesla coils, and laser systems, as well as articles on nuclear radiation detection and other specialized topics. The site also features current laboratory projects, a searchable collection, a feed of recently updated pages, and a wish list seeking documentation and accessories for historical equipment. Bunker of Doom states that it does not charge for its hobbyist resources, display annoying ads, track visitors, or sell personal information. It also points readers to Magnetosphere Electronic Surplus, a surplus supplier that hosts the website.
