I feel very dumb for buying a bunch of tiny LiPo chargers that do 100mA/500mA when all the cells I have are chonky 2200mAh cells that'll do 1A+

Those chargers work, but they'll take a while to charge higher capacity cells like that.

Yeah, that's what I mean DX I should have gotten faster chargers and not the baby ones
late fulcrum
Some of them are capable of higher current, you just swap the current control resistor (or sometimes, tack another resistor in parallel)
delicate stream
Yeah, the little guys can do 500mA at least... I did get a couple of the PowerBoost 1000, so I can at least do a couple at full speed
I guess it also doesn't really matter because I'll get like 10+ hours per cell for most of my things and I'll have the ability to swap with spare cells

If you send the sine wave to one axis, and the 90° offset one to the other axis, the scope plots a circle. Amusingly, this scope uses a sine wave as a calibration signal, and can also use it as a sweep signal, with variable phase shift, so you need no other equipment to do this.

What is the difference between CVT and standard automatic?
Rather than having a set number of gears that have to disengage and switch before re-engaging, a CVT (Continuously Variable Transmission) has an infinite gear ratio and never disengages. There are a few different designs, but a common one is two conical gears that move against each other to change the gear ratio. It's much more efficient because the engine is never spinning freely when in Drive/Reverse, so power is always going to the wheels.

The case keeps the screen from lifting up which is nice though 🙂
https://learn.adafruit.com/adafruit-pygamer/troubleshooting-2#screen-adhesive-fix-3033119-4
The screen can become un-adhered pretty easily -- these screens were originally designed to be secured with a bezel. Your PyGamer case does a good job of holding it in place, but if you have it out of a case, it can become unstuck.
Luckily, it's easy to fix! Just use two strips of double stick adhesive tape to hold the screen down to the backing plastic.

"Descriptive robot programming is an active research field (not mine though).

You could say these relates to "objectives". Your list of commandments sounds more like "constraints". Constraint programming is also a hot topic.

How can a function have more than one integral
wooden schooner
If F is one of them, then so is the function G defined by G(x) = F(x) + 7
And yes, adding a constant like that is the only way. If F is one of the indefinite integrals, then all the other ones have the form G(x) = F(x) + C for some constant C

If you're contracted to do a job within some number of hours and agree to an hourly rate, you end up losing money from working too quickly, as early termination means the contractor doesn't get paid the full amount of the contract.

Depending on where you live, several places sell them. In the U.S., I've seen them at Lowes, Home Depot, Container Store, Target and other retailers
You can try asking at a store, but ages ago, before the turn of the millennia, I used to work for a convenience store, and we were charged a decent amount for each crate that didn't go back

On the other hand, go to a local grocery store and ask nicely if they have any Tomato or Apple boxes. They're very well made, and most of them are crushed. Sometimes they're asked to be sent back & reused.

Is there a piece of basic hardware that has a name and already does this? Or, what's the simplest way to do this?

tardy badger
It’s a little bit slower computationally but for the ease of use, it is a worth while trade off

Python is loosely typed so it’s more natural to program in

wooden schooner
oh well that's cool
I still don't have great intuitions about what kind of microcode would be simple enough to run on a microcontroller but complex enough to have there be a big difference in ease of writing in C++ vs. CP

what is the less-convenient alternative to this?
tardy badger
Making your own ROM bootloader and burning it the the microcontroller
wooden schooner
making?
tardy badger
You do this with SAMDx1 microcontrollers
You use a tool like Microchip Studio or the Adafruit uf2samdx1 library to make a binary file for a bootloader to load using a DAP SWD programmer
wooden schooner
would this binary file be a blob you download from the manufacturer's site (or community forums if the mfr didn't put one out), or does it actually need to be written by more than one person in the world per device model?
is the idea that different people would have different things they want the bootloader to do?
tardy badger
Let me find you what I use to make my binaries
It says samd21 but it works for the samd51/54 as well
Basically you make your board directory and change the make file configuration file and board definition
wooden schooner
ok, so you pretty much write the bootloader once per board layout
that makes sense
I forgot that the "manufacturer" I referred to above was the chip manufacturer, not the board designer
also wow, I just looked up adafruit's RP2040 feather and I see it's cheaper than the metro mini. Is its hardware not fancier than the metro mini's in every way?
sorry for being a noob so full of questions
tardy badger
Yeah, microchip provides the template but you have to fill it out to your needs
Rp2040 chip is just ridiculously cheap
Like, I buy for my company at $0.50 a piece because I buy reels
Biggest expense then is to cover hours costs and rising cost of other components
wooden schooner
ok, so adafruit is presumably also getting these things for $0.50 apiece then?
tardy badger
Presumably
wooden schooner
do you know off hand whether the metro's ATmega328P costs a similar amount when bought by the reel?
tardy badger
Not likely.
wooden schooner
why not?
tardy badger
A reel of 2000 will cost ~$2 a piece
wooden schooner
oh as in it costs much less
I thought you were saying it would cost more, and I was interested in why that would be
oh wait
a piece
ignore all the above
tardy badger
Yeah
wooden schooner
unless they're getting an outside subsidy, I don't see how they are then able to make it cheaper than a big company
tardy badger
They don’t have massive budget lines to fill with the RP2040. They basically price it just enough to cover overhead
Chip makers mark chips up a lot
tardy badger
The atmega328p costs like $0.30 to make
tardy badger
Profit is the motivation of high prices
wooden schooner
right, but like, some nice-sounding economic theory might say that in the right kind of world, competition would drive the prices down to near actual production cost
and oligopolies are one way to not be that nice world
tardy badger
At one point before the chip shortage you could get the 328p for $1.90 a piece for a reel
The problem is, the 328p is the original arduino

I try to find the relation between fancy and education.
I really do not know for sure if fancy is really education or not.
delicate stream
Yeah, being "civilized" and knowing how to behave in fancy parties is considered "educated" in some cultures... But I mean, the word "educated" basically just means you're well studied/taught in a particular field or fields of study, so someone could be educated in running a farm, and a lawyer is educated in, well... law. So both know how to do their jobs, but not each other's, but they're both educated

The sheer number of these photos, surely at this point its transitioned from someone really not knowing what they were doing, to photographers copying off each other and just being like "yep, that looks right to me". How funny would it be if they were searching for how to set their photo up by searching on the stock photo website they want to sell to instead of doing any actual research

My favorite thing in the world is getting a pay raise that doesn’t compensate for inflation
So my starting salary on Jan 4th was $79k to be a software engineer.
Projected 2021 inflation is expected to be around 3.4%
Assuming no pay raise, that $79k would be worth $76,314 in inflation adjusted income
I got notified of a raise today of 1.9%
Or $1,500 added to my salary
delicate stream
I wish I could get a raise
tardy badger
Which means even after the raise my salary is worth $1,207 less at the end of the year than when I started
Hashtag economics
Granted, plenty of people didn’t get pay raises in January this year
And plenty of people were laid off
I’m not mad about getting a raise, just disappointed that when adjusting for inflation I’ll end the year making less than I started 😣
Just an example of executives reaping the benefits of the workers and not rewarding the work appropriately

I've only gotten one raise in my life... Went from $10 to $10.50 an hour.

I finally got around to trying a board I bought a while back, but apparently the software now only supports later versions of the board, grump. 😦
That was a SparkFun board. I recently tried an old XBee board, and had to do a bit of a dance with the software to recognize and update it. I also tried an old AdaFruit board, but that was the nicest of all: the software automatically updated the firmware for me.
tardy badger
Adafruit is great in that regard
I just posted something about board pricing on Twitter and scale of manufacturing really goes a long way
The Pico is $4, costs RPi like $1.15 or so to make
The Qt Py RP2040 is $9.95 probably costs Adafruit ~$3.20-$3.70 to make
The Xiao RP2040 is $5.60
It means they are making them at a similar cost to the Pico
My Bread RP2040 will probably cost like $12.95 or in that range
