Verilog describes the logic. This is extremely simplified, but you can imagine that verilog and other HDLs are "compiled" into a big schematic of logic gates and a big list of signal timing constraints between them. From that sche

For a 4 by 4 hexadecimal keypad with 0x0..0xF keys in any sequential row or column arrangement the same will be true that all possible numbers will be a multiple of 0x11. This holds true for any size square keypad; the common multiple will

The problem with DIY perks solution is that the manchester clock+data encoding is an amplitude modulated thing and isnt really very robust to using in free space. LED bulbs, sunlight, or all manner of other stuff can and will fuss with it.

A hogel volume can be reduced into a 1bpp 2d plane representing the interference problem. Literally, a hologram. Probably the computational effort to do this in realtime is within reach of current GPUs.

Sorry, but I will continue to disagree. For a $6500 device the quality, resolution, and spatial continuity is utterly unacceptable. As a DIY project or a product that is price aligned with other LED POV products with similar BoM costs I wou

If I implied this was a singular product, I apologize. There are quite literally hundreds. Searching for "Hologram Fan" will pull up the type I am specifically referring to as being a current fad, but the number of other LED POV d

CanAm's tadpole trikes have a tilt/camber mechanism on the front wheels and can lean; it's not at all the same thing as a 2 wheeler but it's a light year better than the delta configuration.

In the early days at my company, we had an arrangement where the CEO had 3 monitors on his desk. Two faced him, and one faced the other direction and mirrored one of his screens. There was a second keyboard and mouse attached so that someon

First, the delta configuration is inherently unstable. If the trike gets any kind of side force at speed it becomes very difficult and unnatural to control and recover. In almost all cases when a delta trike loses control at speed it will f

Yes I think I actually spotted this in their video demo where you will notice one of the displays looks way way way better than the rest of them. That would be a projector one. It is considerably easier to achieve sync and high framerates w

Anyone who thinks that kei trucks shouldn't be on roads and highways and motorcycles should ought to have their head examined. For the record I support both, with the exception of 3 wheel delta configuration motorcycles such as Harley&

Hot take, but once the novelty wears off, POV LED displays like this just look like absolute garbage and are uselessly low resolution. Before LEDs this type of volumetric display originally rotated a helical or tilted projection surface and

I mean they did… a number of times. Current CUPS and MacOS prefer to use IPP when supported. However as a de facto standard you can dump postscript or pcl to port 9100 and most good printers will happily oblige you. The problem AirPrint end

It's a proprietary edge connector that connects the dock and the mini PC, but it carries standard PCIe, so it's at least twice as fast as Thunderbolt. To me all of these Mini PCs are essentially uselessly uninteresting without fas

I always ask the robocalls to say something specific. It finally worked the other day! A robot repeated "chrysanthemum" back to me when asked. Sadly it seemed to be limited to this one single trick; as I continued my attempts to e

Boy howdy, wait until you hear how rural phone companies make money. There is one simple and easy solution to this mess, but good luck getting traction on it.

If every third call you make goes to Daisy you are using shit data and are likely part of the problem. Are you absolutely sure they are fucking up the spam detection, or are you just doing all of your cold calling with blinders on?

I have driven my vehicles 70,442 actual miles since Jan 1, 2018. (Thanks to TeslaFi I have actual data -- I didn't drive all of these miles in TX, and while I have that data, I'm not going to be pedantic about it.) The revenue to

Yeah sorry about that I was ballparking it pretty good; your numbers are truer. But if we are going to take it into this territory, we do need to break down those taxes a little bit to make a proper comparison. On the state tax side, 75% of

You are woefully incorrect. in most places EV's road taxes are massively disproportionate to the amount of road tax an ICE vehicle would pay. Here in Texas, I would ordinarily pay about $30/year in road taxes on gasoline driving a

IMO fully mechanically milled PCBs are kind of stupid; you are never going to actually manufacture them at scale this way, so what is the point in jumping through the DFM effort to prototype with such a constrained process? There used to be

This article doesn't really focus on the details of the power, but I'll mention that the power requirements of Raspberry Pi 5 are a bit weird and this can have some implications when powering one from a limited current source. Ide

I see you too have wrestled with GreatData's time zone data being hot garbage. Been that way for decades.

Every country is different but I'd be surprised if they don't still have it. The irony is they will probably still have to burn it on a CD and mail it to you. Good old DICOM!

For anyone whose brain is still in their head and/or doesn't have 7T data, there is also FreeSurfer[1] to play with. I only really know about the physics of MRI, so I admit I don't fully understand what the advantage of this

If you are accelerating, the accelerometers will not "show 0". I have no idea where you are getting this notion from; it's completely wrong.

> An accelerometer glued to the mountain will show a 0. Incorrect. An accelerometer glued to the mountain will show -9.8m/s^2 because it's being accelerated by said mountain.
