I assume (?) there are differences in mechanical strength of the printed item relative to forces exerted along vs. normal to the laminations. Is this a significant difference (i.e., one that would suggest printing in one orientation over another)? Also, does this (?) generality apply to all materials? Or, some moreso than others?

I brought and use them as 12V 5W zeners in 32S4P 400V 1A. When balanced, each 1N5439 draws around 400/128 = 3.1W. Occasionally, i got smoke signals with them. No big deal when close to home, but headache trouble shooting on the road. Is there a better part I can use? Some manufacturers list it as "Varactor Diode". https://www.alldatasheet.com/view.jsp?Searchword=1N5439

I'm planning on operating a couple of 1U servers "on their sides" (i.e., tall, deep and VERY skinny). Of course, this is normal to their expected operating orientation. I figure the disks won't mind being operated in that orientation as I have shelfs with (the same) drives oriented that way. 1U servers tend to have a bank of redundant fans located behind the drive array to produce a fl...

I have a centre tapped transformer I wanted to get the most power out of. Thinking a traditional full wave rectifier (just a diode on each side, calling the centre tap 0V at the output) is only running current through one half of the secondary at a time, which is inefficient (think of P=i^2R), I thought about putting a bridge rectifier on each half, then connecting the result in parallel. I made...

An electrician (who I don't believe) told me if there's too much power on the grid, they use wind turbines as fans to absorb extra power. Is this really true? Aren't there plenty of power stations they can just turn down a bit? Take your foot off the gas so to speak? I was also disturbed to hear from him it costs £700 to install smart meters into each home. And in the UK that

Researchers highlight nucleolar DNA damage response in fight against cancer https://www.sciencedaily.com/releases/2023/03/230316113153.htm Researchers have now encapsulated the young field of nucleolar DNA damage response (DDR) pathways. A new review highlights six mechanisms by which cells repair DNA damage. By attacking these mechanisms, future applied researchers will be able to trip up ...

I have a Micromark surge protector. Just a plug (not as in to connect an appliance, it just plugs into a socket to absorb surges, no cable comes out of it). I was interested in the LED on the front which says "protection active", so I opened it to look inside to see how it knew if it had expired. What do I find? An array of varistors as expected, but the only connection to live was through a c...
