Lenovo’s retro ThinkPad 25 laptop leaks | 19mm Momentary Push Button

If you’re totally stumped on a page of Where’s Waldo and ready to file a missing persons report, you’re in luck. Now there’s a robot called There’s Waldo that’ll find him for you, complete with a silicone hand that points him out.

In reviewing my experience with the Sony A55 and A33, it’s interesting to find so many of my notes and so much of my attention directed to the viewfinder display. Were I not already so familiar with Sony’s multi-shot exposure technology, the camera’s multi-shot features would doubtless have commanded more of my attention, as they’re worthy features indeed. That said, though, the viewfinder turned out to be absolutely integral to my experience with the camera.

They make silicone pad heaters for automotive stuff like someone else mentioned, that would probably work too.

In cases of energy shortfall, we could apply 3% or 6% voltage reduction from our central control, to shed load. (along with asking manufacturers to reduce load, part of their contract) Before real load shedding, switching off supplies. I know. I was a control engineer. Admittedly a few years ago

The best tip for buying a portable home generator: Don’t wait until the lights go out. Whether you live in a place at the mercy of snowstorms, hurricanes, heat waves or an outdated electric grid, a power outage can range from an annoyance to life-threatening.

Samsung is rolling out an update for its 2018 lineup of QLED TVs that enables FreeSync, which allows for smoother gaming without screen tearing. The company talked up its partnership with Microsoft’s Xbox division during its unveiling of this year’s sets, and this is yet another feature that embraces the capabilities of the Xbox One X.

But at the very same time, if the rectifier dissipates enough energy for this to be a concern, then it is probably a poorly designed power supply to start with. As most power supplies will be designed for the voltage range of 110 to 250 volts AC. And as it will draw the most current down at 110 volts, then this is where the manufacturer has their specifications chiseled in stone, as if we want 1100 watts, then we need at least 10 amps when we have 110 volts AC on the input. This means that we “effectively” have 5 amps to dissipate per diode.

https://en.wikipedia.org/wiki/Electric_shock#Factors_in_lethality_of_electric_shock If the current can be limited to Less than 30mA or less people should live, see the graph in the above link. This is much easier to achieve with lower voltages because the human body resistance is higher with lower voltage shocks ( https://en.wikipedia.org/wiki/Electric_shock#Body_resistance ).

Also I have seen opto-couples where the pins have been spayed out to gain an extra 0.1″ between the rows of pins.

In my college days, designing stage lighting systems for customers, I had a test rig that I used during a sales presentation. The reason I built this is that a customer had his electrician contracted to do the install work (we didn’t do the electrical install, just specification). When I specified 20 Amp breakers and told the customer that they’d be limited unless they upgraded their service, they told me that their guy had taken care of it.

Engineering types have been known to reduce “Preventive Maintenance” in the large “Mains” switch panels in an attempt to save budget funding. A close friend stepped up to a sadly neglected switch panel, pushed the dis-connect and the panel door blew off in his face. It seems that dust is conductive, and will explode if a large spark is present. The good news, he is alive, and was promoted to avoid a lawsuit. :cheers:
