I'll second DMM. Unlike most servo companies, they post their pricelist, making it easy to figure out which tradeoffs you need to make to stay on budget: https://dmm-tech.com/pricing.html

If you're familiar with electronics: Imagine you have a current source, driving 1 amp through a variable resistor set to a very low resistance. It only takes less than a volt to sustain that current, so your current source is quite hap

I think it's beyond that -- with interest rates rising, companies need to increase earnings or else decrease their expenditures, in order to maintain their valuation.

11/8.5 = 22/17 = 44/34 = 1.29 17/11 = 34/22 = 1.55 These have the property that they alternate aspect ratios every size, so you have to go up two sizes (4x area) to get back to the original aspect ratio.

My guess is that the factory did not want to publicly identify its customers.

This is a very important application and a tougher problem than most would guess. There is a huge variety of ways to numerically implement even a simple transfer function, and they can have very different consequences in terms of rounding a

I use calculus quite a lot, basically any time I need to go beyond an existing solution I could look up in a textbook. That is, all the interesting problems! For example in writing this article, especially details in footnotes 4 and 13: ht

Theoretically, you're attempting to remove the artifacts that were added back in by the halftone printing process and recover the original image. If you knew the exact noise spectrum that the halftone print added into the image, you co

There's not much you can do to fix it in software, but you can fix it in the optics. You can add a Moiré filter to the camera, which is an optical low-pass filter, ensuring that the image that reaches the sensor does not have any spati

For sure! I also wouldn't bet on a coin flip offered by a guy standing next to a 500-kg servo-driven coin-tossing machine. But their confidence in offering me that bet is also useful information to update my probabilities. (This is als

I totally agree! There is definitely a difference in that repeated boxing matches are not independent probabilities. But honestly, if I put on my precision engineering hat, the fact that repeated coin flips are independently 1/2 just

The Toyota Way emphasizes that managers cannot merely read and listen to reports. They need to walk the genba , the factory floor, and see firsthand what the state of things is. With software, the genba is not the office. It is the codeb

In Canada, if you have a P. Eng, you can do that (and, in fact, must). (I don't know how many software developers have P. Engs though. The regulators try to extend the coverage of their regulation to encompass software and tech, but at

Just an aside, but in addition to graphics, this kind of thing is also relevant to motion control applications, where you have some kind of trajectory that you need to follow and must discretize it into a series of servo motor coordinate po

Depends on who I'm talking to. An estimate is not actually a number, it's a probability distribution. Few people want to hear that; they want one number to summarize it. But not everyone wants the same number. My team wants to k

At a hospital or clinic, it is common to be repeatedly asked your name and birthdate, even by the same nurse. It's not because they don't remember your birthdate. It's a procedural security measure in a busy, complicated envi

For what it's worth, it seems authors can disable that popup on their own substack. I did, and it doesn't seem to have reduced subscription sign-ups, but even if it does, not annoying people is always a good principle. It defaults

If you're budget focused, you can stay at a decent business hotel for about USD $30-40 per night, so $280 for the week. Add a modest dine-out budget of USD $20 per day (sans alcohol) and you'll be pretty comfortable.

I've wondered this too. You could set the gear in neutral, connect the AC power directly to the motor terminals, and then basically run the inverter in regenerative mode. It looks elegant on paper, at least, but I'm sure there are
