My coach was saying she preferred the tell-it-like-it-is British commentary ("That's a devastating defeat for the xxx who has been improving and really expected to place") to the candied-up American commentary ("all that

Yes, the technology is the same. But how many machined products were available for the consumer to buy in 1970? I was excited about the Macbook Air not because it was thin, but because it was CNC made, just like the aerospace products I d

I currently have a robot washing my clothes, another robot washing my dishes, a third robot vacuuming my floors. Cybernetic systems adjust the temperature in my house and water my lawn. I even have a little robot I keep in the freezer to ma

For Covid, I restored an HP-87. What's cool about it is the processor is fully custom, so a new assembly language to learn. It's too old that no one ever made a C compiler. The assembly is all in octal, which takes time getting

I've been feeling just the opposite - I've been using an IDE from the mid-2000s for a legacy project, and it's amazing how things have changed. The search function dings a bell if nothing is found, and it does it in real-time

Yep, that would help. From what I can tell, the wheelchair patent is aspirational and they haven't actually implemented the majority of standard autonomous vehicle practices.

Sixteen years ago, I had the idea for headlights aimed by GPS and started to make some prototypes. Then I read a patent that was basically "a plurality of inputs + processor -> headlight aiming" that covered everything imaginab

But matching the schematic to the picture, the double wires are on the base. It makes me think it's a double-base transistor, but both bases tied together because they don't need two for this circuit. If it was for reliability, I

The obvious solution to carrying 20kg would be to have 10 of these robots following you.

I'll add on to the good points other have made here - smaller planes tend to fly out of small airports in the suburbs or the countryside. Larger planes fly out of much more urban areas, where there are a lot more obstacles, making a sa

It's obnoxious on a giant screen, too. I get 10 headlines on the old version, but the new version only shows me one story -- so much scrolling.

Yes, what Ken said. There was another way to do it if the memory chips were already wide enough. Some static RAMs had multiple enables of different polarities. For example, the 6264 had an E1* (active low) and an E2 (active high)... wire a

I did something similar for a high speed (10k rpm) stepper motor driver. We were emulating a legacy system and needed to do a 24 bit/16 bit divide, which took a long time. Even worse was that when the speeds increased, we had less time

XEONs use a 100MHz referenced called "BCLK" and scale this up to the different frequencies it needs internally (core, dram, pci, etc.). Typically this info is found in the datasheet, but only the DC parameters (voltage min/m

So much less than the 0.01% of the variation in identical computers due to 100ppm crystal variation. Also less than the 0.0001% variation due to the temperature in the room changing 1 degree.

You'd want the inner pane to be actual glass, too, so you can clean it with water or handle humidity. But at that point, the gap in a double-paned glass will insulate better. I wonder if you could sandwich this in to one piece, like a

There are lots of fabs, but not all specialize in techniques used for imagers (like backside illumination). I worked in LCOS and we had one vendor qualified that could produce a shinier metal layer -- something most fabs wouldn't care

This article gives bad advice. It should say "Don't overspend on a car", or, more generally "live within your means" The example of the basketball player who makes $100MM driving a 20 year old car doesn't help.

These tech companies aren't direct buyers any more than you or me. Ore is sold to smelting companies, who sell ingots to sheet metal companies, who sell it to electronics component manufacturers, who sell it to contract manufacturers,

It might be patchable, even though it's in ROM. The ARM chip I've been working on has a mechanism to change a few words in ROM by blowing fuses... basically, between the ROM and the CPU sits a device that compares addresses and if

Professional DMMs are nice because they've thought through all the failure cases. This meter is nice, but the relay on the current range select (K2) is set up so that there will be a break in the current when it switches ranges. On in

Exactly. Solar and wind don't need fuel to be stored on-site, so they should benefit any national security needs. Yet, they are excluded from this latest picking-winners-and-losers subsidy.
