Its also clear that the carrier wasn't ready for it. People with the original iPhone would get entire boxes mailed to them for their Cingular statement, itemizing every data transaction, but then all flat rate charged.
Simple: motor inverters are switching power in this frequency range.
It’s already below FCC limits for unintended radiation - it’s not going to block AM activity far from the vehicle, but putting the antenna in the midst of all that radiated noise is challenging.
Lower cost printers are absolutely using LCDs with an LED UV light source. These resin curing printers are pretty darn cheap as well, and have a ton of resolution. They also excel on volume as they do expose the entire plate at once and don’t require scanning a laser around.
The material you get out of such a printer is of course entirely different from an injection molded part.
Usually a combination of calcium carbonate (or bicarbonate for solubility), calcium chloride, magnesium chloride, and or the sulfate versions of the chlorides.
The ability for contract manufacturers to simply source things from neighboring companies is a very real thing - and usually the quality is pretty good. Somehow, working between companies is a quick and fast thing, where here making a new business relationship is seemingly mired in problems.
SolidWorks (and Catia upmarket), Siemens NX are the two most popular in the field that Inventor/Fusion plays in. 2d Autocad is pretty entrenched in some industries with no real competition.
KiCad is getting better and better. At this point Altium is copying features _from_ KiCad, so you know the competition is real :).
Altium is still a Delphi-ish program, though with lots of things now just compiling to .Net. The core layout package has always been solid with a very small core developer group running it which is really more what its known for. The library management parts with collaboration are actually getting a lot better (ECAD<->MCAD, etc).
Altium gained tons of weird stuff with a super weird push to "FPGAs for everything", a giant off-shore (not Australian or Carlsbad) development team, and... all of that crash and burned and no actual customer actually understood what was happening. Much of that legacy is still in parts, but most of the features have been removed by now.
Stop down and take a long exposure. You just want to avoid the focal plane shutter or digital rolling shutter, and capture one beam paint, or lots of beam paints to even out the intensity.
It has nothing to do with filaments and is all with the phosphor coating. Standard white LEDs intentionally bleed the base blue LED through, whereas PCA LEDs do not.
I'm working on a bit of a hobby project to rebuild a beefier Mascon. Mainly inspired by how much I enjoyed Running Train
