In the old days, the idle was only controlled by a simple mechanical adjustment which lets through a fixed amount of air, which means the engine makes a roughly fixed amount of power. When you let out the clutch, the revs would drop a lot,

That's determined by the coefficient of friction between the load and the surface. A coefficient of 1 means the force to drag is equal to the normal force (ie, the dead lift). Most things (including moose fur on soil) have a coeffici

The RasPi kinda is that, at least when they're in stock. There are several IP camera software loads for them, whether it's for local storage, or streaming over the network.

Try using "pv -d <pid>". It will monitor open files on the process and report progress on them. 1) this gets it out of the pipeline. 2) the program gets to have the named arguments. 3) pv's out put is on a separate ter

That's one reason, but the big one is that it makes it easy to remote-power the sensors. It gives them a 4mA budget to Do Their Thing even when outputting a zero.

Because it was a black and white camera, it only had a single IR filter which was easy to remove. The bare silicon sensor, unhindered by RGB color filters, had surprisingly good near-IR performance. We rigged up a bunch of IR LEDs and had

_Why's (Poignant) Guide to Ruby is what got me hooked. His quirky little foxes made it fun to just burn through the whole book and left me with enough knowledge to be useful, and able to ask the right questions to learn more. It was j

Vacuum won't work with current technology. The heads use air currents to fly a few nanometers over the platter. If you put a running drive in a vacuum chamber the heads will touch down and everything will be destroyed. https:/&

Also give https://kdenlive.org/ a try. I settled on it as a high-power, steep learning curve solution when I found myself hitting the wall with alternatives. It's clunky but it does everything I need. Like Shotcut, i

Most breakers do not trip instantly. They are designed to protect the wiring insulation from melting. Because the wires have thermal mass, a brief pulse above rated power is fine. Your 15A A/C may pull 30A or even 45A for 100ms whil

I wasn't able to find a reference, but I believe it's possible to go to a blood drive and have blood drawn and discarded. This provides cover for people who are ineligible but don't want their friends/coworkers to know.

Some cars unlock when you're close, no button presses required. Relay attacks let the thieves use the keyfob inside your house by relaying the signal. A faraday pouch prevents this. It's not related to replay attacks on a tradi

Long ago, I worked in a shop that I feel did it the right way: allow techs to sign up for pager duty a week at a time, and each week would pay a bonus of a few hundred bucks. It was always voluntary, and people were eager to take as many s

Try applying load to the CPU and see what cpuinfo_cur_freq reports. If I boot my ThinkPad W530 (workstation laptop with a large power envelope) with no / dead battery, it will say full speed is available, but it will remain at the min

This article misses a key point: Ethanol is used to oxygenate the fuel, which reduces carbon monoxide and soot emissions. It replaced MTBE in that role. It was never intended to reduce greenhouse gas emissions. Producing it requires more

They are using a 168Wh battery and a 30W panel, so a naive first approximation would be 168Wh / 30W = 5.6h to go from 0% to 100% capacity. In reality: * The panel won't be pointed squarely at the sun most of the day * The sun won
