Low cost ferrite


October 19, 2020, 11:02 pm

Hey As always, I am looking for saving cost (who isn't) I'm doing a new power design, and looking for cheap ferrite. Run of the mill, N87, PC95 etc, nothing fancy. In this case it's a planar design... Read more »

Re: OT: 3D printer infill for round spacers?


October 19, 2020, 4:21 pm

It doesn't really matter since the force is almost always down relative to the print. I almost always use the old rectilinear grid infill because it's fast and nearly as strong as others in the do... Read more »

OT: Carbon fiber reinforced foam


October 18, 2020, 4:06 pm

Could you build a re-inforced box-girder like structure out of rigid polystyrene foam by sandwiching it with carbon fiber tape + epoxy? Carbon-fiber plated foam core is filthy expensive, but raw p... Read more »

differential signal detector


October 17, 2020, 7:59 pm

I probably won't use this one, but it is pleasingly weird. Watch for line wrap on the BAT15 model. Version 4 SHEET 1 1724 680 WIRE -416 -352 -480 -352 WIRE -368 -352 -416 -352 WIRE -208 -352 -2... Read more »

faster PCB laminate


October 16, 2020, 6:21 pm

We normally make boards from FR4, specifically the Isola 370HR or equivalent. It's usually fine but is lossy for fast stuff, like 100 ps edges on long runs, long being maybe 1 inch. We've used tef... Read more »

STmicro acceleration/magnetic sensor LSM303DLH == LIS331DLH + HMC5834?


Just had a look at the LSM303DLH datasheet and had a déjà vu ;-) It looks like ST has simply put a LIS331DLH and a HMC5843 into one package. (The HMC lacks the built-in voltage regulator) All data ar... Read more »
