How Etak Paved the Way to Personal Navigation

Our current “Retrotechtacular” function on an early 1970s dead-reckoning car navigation system stirred a reminiscence of one other pre-GPS resolution for the query that had vexed the motoring public on highway journeys into unfamiliar areas for many years: “Where the heck are we?” In an age when the tattered stays of long-outdated paper roadmaps have […]

Move Aside Mercury: Measuring Temperature Accurately with an RTD

Move Aside Mercury: Measuring Temperature Accurately with an RTD

Temperature is among the most steadily measured bodily portions, and options prominently in lots of our initiatives, from climate stations to 3D printers. Most generally we’ll see thermistors, thermocouples, infrared sensors, or a devoted IC used to measure temperature. It’s even attainable to make use of solely an ordinary diode, resulting in some interesting techniques. […]

Watch a very detailed overview of the latest innovations for power in space

Watch a really detailed overview of the most recent improvements for energy in area

Improved super-thin photo voltaic panels and nuclear fission are all in growth to deal with the huge logistical issues of meeting power needs in space. Fraser Cain takes viewers via the most recent developments, together with NASA’s new Kilopower Reactor. Space is the worst. It’s acquired hostile radiation, a complete lack of ambiance, close to […]

3D-printed mini-submarine can move in water without a motor

3D-printed mini-submarine can transfer in water with no motor

A motorless mini-submarine has been created by researchers from ETH Zurich and the California Institute of Technology. The 3D-printed vessel strikes utilizing a brand new propulsion idea designed for swimming robots, enabling it to paddle with out engine energy. By responding to temperature adjustments in water, the robotic strikes its paddles forwards and backwards, gently […]

Pipelining Digital Logic in FPGAs

Pipelining Digital Logic in FPGAs

When you first study digital logic, it in all probability looks as if it’s straightforward. You study AND and OR gates and determine that’s not very exhausting. However, going from just a few primary gates to one thing like a CPU or one other advanced system is a complete totally different story. It is like […]

Raspberry Pi’s Power Over Ethernet Hardware Sparks False Spying Hubbub

Have you ever torn open an Ethernet jack? We’d guess the overwhelming majority of readers — even those elbow-deep into the world — will reply no. So we applaud the trouble on this one, however the conclusion landed way off the mark. In the previous couple of days, a Tweet displaying a Raspberry Pi with […]

Watch a nanorobot build a microscopic house on the tip of a fiberoptic filament

Watch a nanorobot construct a microscopic home on the tip of a fiberoptic filament

A workforce led by Jean-Yves Rauch at FEMTO-ST demonstrated the μRobotex nanofactory’s capabilities by constructing a tiny origami house from silica membranes. The work required novel makes use of for a number of applied sciences. Via the paper: In this examine, the authors have demonstrated that it’s attainable to appreciate a number of three-dimensional (3D) […]

Hacking When It Counts: The Pioneer Missions

Hacking When It Counts: The Pioneer Missions

If the heady early days of house exploration taught us something, it was how a lot we simply didn’t know. Failure after failure mounted, usually dramatic and costly and generally lethal. Launch automobiles exploded, satellites didn’t deploy, or some widget determined to surrender the ghost at a vital time, blinding a multi-million greenback probe and […]
