I've been waiting for consumer grade high-speed digital cameras for over a decade now. Looks like they may be getting close, this one can shoot a million frames per second!

The Internet Archive is an amazing resource, but I find it increasing more difficult to dig up older web pages, as links continue to evaporate. Access to the past requires an archival onramp. Mosaic/Mozilla's early web presence and links to internet indexes here date to 1994, pretty much the earliest days of the WWW. From here, you can find those old files you've been looking for, whether photos of your friend's cat back when you were a grad student, or some legacy academic software that has evaporated across the mists of time.

Via the Japanese NASA equivalent.

The two-fisted retro-goodness of the Commando Cody serials speak for generations. Higher tech than Doc Savage, and more down to Earth than either Flash Gordon or Buck Rogers. John Carter of Mars will be in theaters soon, when will we see a Rocket Man remake? This MetaFilter entry is the most definitive linklist I've found in a decade of searching.

Nice writeup. Reminds me of the magnetic apogee detector for HPR back in the day.

Finally, an open source game console with staying power. Bonus points for retro style. I expect it's only a matter of time until somebody figures out how to port Atari/NES games to the system.


From the page: "The Uzebox is a "retro minimalist" game console design based on an 8-bit general purpose microcontroller. The main design goal was to keep it simple so it would be easy to understand and assemble by hobbyists. It's made of only two chips and a few discrete parts like resistors and capacitors. Audio and video are generated real-time in software by the microcontroller as a background task, so games can easily be programmed in C language. It's also fully open source so anyone can make and sell their own version. The console uses an overclocked ATmega644 microcontroller and classic Super Nintendo controllers, supports 256 colors and 4 sound channels and has a SD card interface from which games can be loaded from."
