Very nice online electronics textbook.
Adrian S. Nastase's weblog has some nice, short introductory articles.
Introductory tutorials on many electronics topics. I don't know who wrote these, but it is now one of the many EE websites owned by Aarow/AspenCore.
Sam started the process of making semiconductors in his garage 1.5 years ago.
A look at the LTC3265 charge pump LDO
Quotes from many of the original engineers and a surprisingly clear description of the C64's video modes.
"How the neon-filled glow lamps came to hold a special place in enthusiasts’ hearts"
H.P. Friedrichs (AC7ZL) made this audio amplifier by using a VFD as a triode. A neat idea I've seen on hackaday a few times. Some characteristic curves are provided at the end of the article.
I like these little 1- and 3-key USB keyboards.
Modeling transistors and logic gates with Unix pipes.
"Earl William 'Madman' Muntz (January 3, 1914 – June 21, 1987) was an American businessman and engineer... He invented the practice that came to be known as Muntzing, which involved simplifying otherwise complicated electronic devices. Muntz produced and marketed the first black-and-white television receivers to sell for less than $100"
Hat tip to a recent EEVblog video for bringing up Muntz and the practice of Muntzing.
An overview of JST and similar crimp connectors.
Ben Katz and Jared Di Carlo built this fast Rubik's cube solving machine (six servomotors and two cameras solve a cube in 0.38 seconds).
This project in progress by Radical Brad looks really neat. It is a graphics co-processor (including an entire 6502-compatible CPU?) for the Commordore VIC-20 made in 7400 logic running at 25Mhz on a solderless breadboard (though I think he plans to create a PCB for it eventually).
Linus Åkesson (lft) converted an old electronic organ into a MIDI controller and 8-bit synthesizer using two 8-bit ATmega88 microcontrollers. The synthesizer sounds very NES-ish with its bright square+triangle+noise oscillators. lft is musician and has several videos of himself on youtube playing very nice renditions of various chiptunes (from memory) on his Chipophone.
All about neon tube ring counters, and other non-standard ways to drive nixie tube clocks.
Jeroen Domburg's linux framebuffer driver which allows using a SSD1289-based TFT LCD, connected via SPI, as a monitor.
While I wasn't paying attention, Glen K. finished documenting his analog pong game, complete with nice hand-drawn schematics.
(Original EEVBlog thread: http://www.eevblog.com/forum/projects/oscilloscope-pong-for-1-or-2-players/)
He's now working on an asteroids game: http://www.eevblog.com/forum/projects/asteroids-we-don't-need-not-stinkin'-micro-processor!/
I really like this aesthetic. Now I want to build a little console system based on a display like this.
