Well, one potential issue that springs to mind is that DC 120V might overstress the diodes in the full bridge rectifier. With 120V AC only 2 of the 4 diodes are active at any one time and on average each of them is on…
If hackers can "affect sensor readings" before they feed into the control system, sure. But that is not read only access to the sensor... The trivially simple example is a webcam streaming the thermostat output. The…
Huh? I've never participated in crowd sourced funding - so maybe I'm out of touch - but if I gave someone $100+ for a product and they then proceeded to tell me it's about to ship for multiple years I'd be pretty…
Idk of the details of that quote, but it does spring to mind that a gun is far better at range than a knife. So, closing that distance could be better than fleeing if your opponent has a gun and there is no cover for…
Ok, fair enough. To focus on one line item I mentioned ("What about the fractional cost of the machine that actually puts the water and beans together to brew the coffee (you could do some sort of analysis based on…
What do you mean by "make profit from that cup of coffee"? A cup of coffee is hot bean water in a cup - is profit simply the price Starbucks charges minus the cost of (water + bean + cup)? What about the cost of energy…
> Just because you lost money doesn't mean you dont make profits until you earned back that money. Taxes should be paid every time you make money in the country your business operates in. Over what timescale? For…
Wow, the UX kind of sucks. I just wanted to browse the devices - no way to do that, only option is an 'ai' search. Ok, I type in "Show All Devices" and it canoodles for about 30 seconds (great use of compute resources)…
>> You think kids aren't running across the street at night out in the country? Chasing a soccer ball? >Only in well light areas, usually with a low speed limit too. Not something I've commonly seen when driving, but…
If you aren't fussed about galvanic isolation there are many SMPS topologies that don't use transformers. Cheapest step down converter would be a simple buck regulator - no transformer needed!
At least with American currency it varies, e.g. one dollar is $1 while one penny is 1¢.
A great many people when they see a open straight road with little obstacles or pedestrians will go 45-50 MPH. A great many people when they see a 15 MPH sign will go 20 MPH. Pair that low speed limit with a "fast" road…
