There's lots of press about the 2019 single-part 10BaseT1S & 1L standards. It's designed to replace 4-20mA systems via existing single pair cable. I'm wondering re: media converters to existing 100BaseT etc LANS. I've found zip so far... Anyone seem same? -- A host is a host from coast to coast...............wb8foz@panix.com & no one will talk to a host that's close....................

https://www.dropbox.com/scl/fi/lujsxfrwlaiocsa2y7k60/P942_DC-DC_12.jpg?rlkey=jslmsa1si2kwbk3l00w ph9dhe&raw=1 My PCB guy is overloaded, so I've taken over my board layout, which is another 3-phase alternator simulator. I enjoy doing a PCB layout now and then. Anyway, that's a floating power supply, +48 to isolated +-60 at about 200 watts. What's scary is that those purple logic traces on l

I need a mechanism to allow for software updates to be installed. The (abused) "on-line" approach is unacceptable (it forces the device to be "exposed" and makes updates too easy (which seems to mean too frequent!). Pisser is that I need a mechanism that will be supportable for 20-30 years. This likely rules out many commodity approachs (will we be using NANO-SD cards? PICO-SD cards? w...

https://www.msn.com/en-us/news/world/concerns-growing-over-the-new-moon-space-race-between-china -and-the-us/ar-AA1jQ6iU This makes no sense to me. Who cares if China or India waste a trillion dollars "establishing norms" on the moon? How many kids are going hungry to bring back more boring moon dirt? And "space" is pretty big. Nobody is going to dominate space.

This user group clearly needs moderation, but moderation doesn't work. The peer-review system in scientific publication does work, more or less, but it is very difficult to get referees to review papers before them got published. What we might use here is post-publication refereeing - if you wanted to react to a post, you have to referee it before you could comment on it. I'm thi

I'm used to an air core inductor having a positive tempco of inductance around +120 PPM/k or so, just from the physical expansion of the copper increasing the diameter. But this Coilcraft midi-spring part https://www.dropbox.com/scl/fi/mfplgwzorhsh5sodxz5cu/Coilcraft_150n_Midi.jpg?rlkey=nrhwa9j64swuz 7bmo1hiyjr9j&raw=1 is much less, maybe +30 PPM. I wonder if the plastic expansion change

Hi I am on the lookout for a cheap 1:1 pulse transformer. Will be using it to drive a MOSFET based Solid State Switch. I know Larkin has used the DRQ127 https://www.digikey.dk/en/products/detail/eaton-electronics-division/DRQ127-1R5-R/667262 But, I am looking to see if I can find bottom dollar. I probably wont go to LCSC, so would prefer a known brand. Anyone got a recommendation...
