I have a test fixture that uses RS-232 to communicate with a PC. It actually uses the voltage levels of RS-232, even though this is from a USB cable on the PC, so it's only RS-232 for maybe four inches. lol I'm redesigning the test fixtures to hold more units and fully automate a few features that presently requires an operator. There will now be 8 UUTs on each test fixture an

We're making devices that are typically built from 3+ "modules" (form factor is highly constrained so board space is similarly). Presently looking at the cost-benefit assessment of burning-in the modules and/or assembled devices. *Modules* will be made offshore so any test/burnin has to be part of the quoted manufacturing cost. Modules will be "post processed" domestically to install f...

Mains power voltage drop to reduce usage?

Instead of rolling blackouts when there's a power shortage, why don't we just allow (or deliberately) the voltage and frequency to drop? Wouldn't...

Instead of rolling blackouts when there's a power shortage, why don't we just allow (or deliberately) the voltage and frequency to drop? Wouldn't that make a lot of devices use less?

This is skybuck's solution for the fermi paradox. The logic is based on USA law which made it illegal for humans to do bussiness with Aliens or risk a 5000 dollar fine and 1 year in jail. Thus it's logical to assume that the USA Government has made it illegal for Aliens to communicate with Earthlings. Bye, Skybuck.

So, why is china stuck on these draconian "zero covid" policies? Of course, in as populous a nation, the potential *cost* to their "system" is magnified. But, are their vaccines (and other remedies) so significantly ineffective that they have to rely on avoidance disproportionately so? It seems an inordinately high price to pay (the damages their economy is seeing seem to dwarf any of the...
