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...

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...

We spend a lot of time rearching parts. I'd like to have a consutant available to help now and then. Anybody interested?
