Collaborate Disseminate
Those shrunken-down arcade cabinets are a nifty idea, but they sure do suck in practice. At least, the Dance Dance Revolution game is full of empty promises. With the $25 …read more Continue reading Mini DDR Cabinet Gets Maximum Upgrade
For those of us who lived through the Cold War, there’s still an air of mystery as to what it was like on the Communist side. As Uncle Sam’s F-111s …read more Continue reading Retrotechtacular: How Communism Made Televisions
There are plenty of bizarre computers around from the 70s through the 90s before the world somewhat standardized around various duopolies of hardware vendors and operating systems. Commodore, Atari, and …read more Continue reading Soviet-Era Computer Is Both a Mystery and a Disaster
Linux users have a lot of software to be proud of. However, there is the occasional Windows program that does something you’d really like to do and it just won’t …read more Continue reading Linux Fu: Reading Your Memory’s Memory
Attack turns SDRAM buses into a Wi-Fi radio to leak data from air-gapped computers. Continue reading Air-Gap Attack Turns Memory Modules into Wi-Fi Radios
This month’s CES saw the introduction of max speed DDR5 memory from SK Hynix. Micron and other vendors are also reportedly sampling similar devices. You can’t get them through normal channels yet, but since you also can’t get motherboards that take them, that’s not a big problem. We hear Intel’s …read more
[Jochen Alt] is on a roll. We just covered his ball-balancing robot, Paul, only to find his phenomenal six-DOF robot arm in full retro style. Its name is “Walter” and it’s done up in DDR style (the former East Germany), in painted, 3D-printed plastic. The full design and build documents are an absolutely amazing resource if you’re into robot arm or legs.
In particular, the sections on trajectory planning and kinematics are fantastic. If you’re interested in robot motion planning by Bezier curves, you know where to go. (We’ve always wanted a Bezier-curve 3D printer slicer, but that’s another story.) …read more
