As with many tasks, robots may soon be ironing our clothes for us before we leave for work. Built by a team from the University Carlos III de Madrid’s robotics lab in Getafe, Spain, TEO is a …

Researchers from MIT and Stanford are taking the ‘person’ in ‘personal assistant’ to mean something more literal with these robots that scurry around on the user’s clo…

We’ve always been fascinated at the number of ways logic gates can spring into being. Sure, we think of logic gates carrying electrons, but there are so many other mechanical means to do the …

How often have you wished you could reduce the size of a drillbit? [Ben Katz] has a bunch of projects in mind that use a tight-tolerance 22mm bore–but he didn’t have a 22mm reamer handy…

The modern internal combustion engine is an engineering marvel. We’re light-years ahead of simple big blocks and carburetors, and now there are very fast, very capable computers sensing adjus…

Engineering student [Varun Suresh] designed his SafeRanger rover to inspect oil and gas power plants for abnormal temperatures as well as gas leaks. The rover explores critical areas of the factory…

Foam core, dollar tree foam board, Adams foam board, or whatever we’re calling a thin sheet of foam sandwiched between two pieces of poster board, is an invaluable hacker’s tool. Everyo…

Few pieces of gear are more basic to electronics than some kind of power supply. It might be a box of batteries, or it might be a high-end lab supply. [Andreas] took a DPS5005 power supply module t…

Even though it seems like there are a lot of operating system choices, the number narrows if you start counting kernels, instead of distributions. Sure, Windows is clearly an operating system famil…

If you were a home constructor in the 8-bit era, the chances are that if you built a microcomputer system you would have ended up with a bare printed circuit board and a terminal. If you were on a …

As a space-faring species, we’ve done a fair job of exploring and exploiting our local neighborhood. We’re pretty good at putting people and machines into orbit, but our galactic-scale …

For the last year or so, Monoprice has been teasing their follow-up to the fantastic $200 MP Select Mini. This is the $150 mini delta printer. We got a look at it last January at CES, it was on dis…
