I’m trying to put a project together basically going from a 3.7 v battery to 8v 15w max with the possibility of charging over usb c and trying to figure out what products would be the best for this purpose
What channel would it be best to post in for feedback?

Got an Art of Electronics question. (Please let me know if there's a better channel for it!)
I'm struggling through AoE 3rd Edition trying to re-learn everything I've forgotten since school (which is pretty much everything). In section 1.4.2 we're looking at an RC circuit that is just a resistor and capacitor in parallel (no other connections). Equation 1.19 says "Cdv/dt = I = -V/R". Where does that "-" in "I = -V/R" come from? Also the text says 1.19 comes from applying the capacitor rules. I get "CdV/dt = I" but what capacitor rule is being used to give the I = V/R ( or I = -V/R) part. Doesn't I = V/R come from the defining equation for a resistor?

it depends on how the variables are defined. is I the current into the resistor, or into the capacitor? (convention is positive current flows into a terminal, usually the "positive" terminal of a two-terminal device)
main dust
Unfortunately the text provides no guidance on that point. The schematic is just the capacitor and resistor shown in vertical orientation with their top and bottom terminals tied together. No other labeling to show a reference direction for I.

Here's the text and circuit
whole jacinth
Here's the text and circuit
right, you've got a parallel circuit, so label the top node as "positive" and the bottom as "negative". you have a single voltage V = Vr = Vc. KCL means the current into the resistor Ir is the negative of the current into the capacitor Ic. Ic = C dVc/dt (capacitor diff eq), and Ir = Vr/R (Ohm's Law). Ic = -Ir, so Ic = -V/R

Thankfully self hosting is made possible by having a static IP
It's also possible with a dynamic IP and a DDNS service.
tardy badger
Easier with static though
I was given a free static IP by my ISP because of the incident where someone bridged a google home router with an old server causing my internet to not work lol..
ebon dew
This is true but you're at the mercy of your ISP who ensures that IP never changes.
yep
Some ISP's don't even give you an IPV4 address anymore they just subnet you into their WAN with a LAN ip.
Like, you are now 10.0.40.134 forever. Have fun running your home network as a subnet of our subnet. It's totally doable but can present other issues like requiring them for DNS services.
These days you can literally tunnel anything you want. You can tunnel IPV6 in an IPV4 address or vice versa.

luckily, I have an IPv4 for each of my WANs, and I try to change them regularly, but I've done double- and triple-NAT within my own network with no troubles
oh, except Starlink is a carrier-grade NAT IPv4 that its router passes directly to my main router
ebon dew
always avoid double NAT situations when possible. triple NAT no thank you. 😬
umbral phoenix
why?
(mine's all on the WAN side, so doesn't affect the LAN... I don't do gaming or port forwarding ... or really anything externally-initiated coming in)
the triple-NAT was a couple years ago... two layers of multi-WAN routers, and then outermost were cellular routers (now with Starlink, I don't need quite as many WANs)
ebon dew
a double nat is more prone to collisions, packet loss, and network inefficiency from double encapsulation. it's better to have one router do all the NAT or for a WAN zone have a zone NAT. you'll have issues especially if you have multiple DHCP servers running in a double nat configuration too. it might seem fine but with diagnostics you'll notice a lot of issues that simply wouldn't exist if you had only one NAT layer per network and using switches for static routes instead of routers. i'm not talking about gaming or port forwarding, though port forwarding becomes more complicated (not impossible) there are many other reasons not to do it.
the amount of effort required to split and/or firewall NAT traffic and maintain a double NAT without any issues is far more than if you didn't have to at all by using a switch instead of a router.
tidal citrus
Is this something you would consider?
umbral phoenix
@ebon dew the outer dhcp servers never reach the LAN though, there’s only one dhcp for the whole LAN
umbral phoenix
the inner router has to be a router, nothing connects to the outer routers except the inner router, and each outer router has a unique address space

Crimping those thing. I have no say of what to get, as the company I work for keeps getting the cheapest option
Sometimes happens that we need to make cables by hand, in case you need a custom sized one, or the connector itself is a bad one

How much twist should be on the wires for CAN-bus twisted pair? I just got a cable from amazon with like... 1 twist for every 4 inches
ebon dew
Just because a crimped ethernet cable shows continuity doesn't mean it's transmitting at full speed. Those little ethernet testers are only good for continuity. If you slice a jacket and introduce crosstalk you'll find the cable has continuity but is continually downgraded to 10-baseT. Just because a cable tests good doesn't mean it's operating at its highest speed (thanks to auto negotiation).
Crimping your own can be a double-edged sword if you're not careful. One tiny little slice in a jacket is all it takes to introduce crosstalk.
That's why people with cats that like to chew on cables really need to hide their ethernet cables in conduit or thick looming.
umbral phoenix
@burnt vale I'm not aware of a standard, you could compare to ethernet, that's probably a fairly low twist rate.
If your distances are relatively short, it probably doesn't matter much. Frequency, distance, twist rate, environment, and other cable characteristics come into play when you're closer to marginal performance.

If the entire project is short distance like near and around a 3D printer within a couple feet then regular twisted pair is fine. The twists matter more the longer the distance.
100 meters of ethernet will have a signifcant amount of twists in that distance. 3 feet... not so much.
burnt vale
yeah but what's the "normal" twist rate?
umbral phoenix
I haven't seen anything about a standard twist rate for CAN. Ethernet I think is 360° per inch, or higher. Longer cable runs may need higher twist rates than shorter runs, depending on other factors.
Ethernet is higher frequency though, and longer distance.
ebon dew
Today I learned, CAN bus wiring should be 1 twist per inch. https://grouper.ieee.org/groups/msc/upamd/pub_docs/CAN.pdf
That is for vehicle CAN bus systems as ISO 11898 is a vehicle standard.
This makes me think CAN bus wiring is a specialty wiring and while ethernet can probably be used, if it's a vehicle project then you'll want that speciality 1 twist per inch wire.
You can always get two pairs of wiring and twist them yourself with a drill. There are drill tips specifically designed for twisting your own wire. You can even 3D print them. There are 3D printed drill tips on printables for it.
umbral phoenix
twist each pair separately, and if there is more than one pair together the twist rates should not be the same
(but CAN needs only one pair if there is one bus)
ebon dew
that's why it's called twisted pair. 😉
CAN wiring is differential signaling so each pair of wires go together.
the same as ethernet really just in a denser twist
umbral phoenix
I wouldn't be too concerned about it with differential at <= 1Mbps, unless the cable run is long or the environment is noisy. I've been running short-distance CAN with no twist.
patent hemlock
CAN is built for a very noisy environment, so a CAD system would be considerably "quieter"
tardy badger
A Canadian system is quieter?
umbral phoenix
Just for grins, here's CAN on a big spool of untwisted bell wire at 500kbps sending a message 20x /sec, no errors

I'm not even sure if something like that existed when I was doing installs. I always used an individual punch down. That could have saved me a ton of time.
Plus if you get into old patch panels you have to use a punch down anyway.
During the process of migrating any company to newer keystone gear you're going to run into a lot of patch panels that require individually punching down each wire. Like, each wire has its own slot on a panel wall.
I love keystones they have made everything much easier. You can even mix them with keystone RCA and other types. I'm all for keystoning all the things.

https://www.ebay.com/itm/186249007611 Just saw this on a podcast, what's the use case for someone that isn't doing crypto mining
thick wind
I believe the main reason was the outdated specs of the SAMD21. As the RAM requirements for newer versions of circuitpython increased, the limited RAM of the SAMD21 eventually became a poor fit for the ecosystem. Combined with the supply shortages during the pandemic and the release of the RP2040, the SAMD21 just couldn't keep up with more economical and well-stocked chips.
Wait, SAMR21? Was there ever a feather for that?
ebon dew
I don't think so, they probably meant the samd21. Even the samd51 is starting to get a little underpowered for projects that require a lot of ram in Circuit Python. It's still a good fit for Arduino projects.

I'm amused that the product description for the #5897 leaded solder says that's it's "good enough" even though it isn't 60/40. I actually prefer 63/37, which is near the eutectic alloy for tin/lead, leading to both the lowest melting point and minimizing the possibility of "cold joints". https://fctsolder.com/eutectic-solder/
Note that the 62/36/2 silver bearing solder mentioned in the article is amazing to use, it has been my primary solder for many years, even though it's expensive. I became familiar with it working on the old Tektronix vacuum tube oscilloscopes, which used silver terminals in ceramic carriers, and required silver bearing solder to avoid leaching the silver out of the metal/ceramic joints.

Depends which Arduino. The Uno might only work for milliseconds before running out of RAM. If you use something like a Pi Pico or other more modern micrcontroller with a lot more CPU & RAM it should be doable. You'll need some hardware supplies like a microphone, amplifier, and headphone jack.
Because the recording you want is likely analog you'll want analog gear like the 3 above. Not a digital mic or digital amplifier though they can be used, most boards have analog capability without the need for an ADC or DAC.

The devs should clean the in-page redirect code and not depend on the destination and fixing it, that is kinda bad web code these days. All in-page style redirects should have been corrected. Must be still there and was missed. I suspect since it correctly worked for me my cache was clean with no historical stuff so I got a clean page load.
It really depends on what you are using on the backend Apache or Nginx and how you set resource aging for a site like how long before a client must get a full reload, I encountered this in Joomla on top of Apache when we had our company website and we had issue reports from people claiming the site was not working as intended but when they cleared cache or we restart the Apache which meant all the resource timers for how long things stayed it the cache got reset the things worked again.

Well they aren't the apple of my eye, that's for sure.
Being professionally on the top of the stack and recreationally at the bottom of the stack, I guess I kinda wonder what the level of practical knowledge exists in your average CPU team about these sorts of classbreak CPU architecture vulns
Because I'd have thought that someone was connecting the dots since the Spectre debacle some years ago but how much of that is just that people at Intel and AMD know some very concrete things and Apple's ARM team just hasn't poached enough of the right people and all.
Either way, these bugs are fun because the combination of work+fun knowledge makes me feel like I have x-ray vision... except for the part where if they attack a CPU I'm responsible for the infra for I'm in for an exciting day at work.
glad ruin
Because I'd have thought that someone was connecting the dots since the Spectre ...
Intel has an entirely businesses unit dedicated to enforcing glorified checklists in an attempt to avoid issues like meltdown/spectre, and they still have issues with it.
burnt tendon
I mean, it's either checklist or you need to find someone who, when they put them in the vortex, gave them a momentary glimpse of of the entire unimaginable infinity of creation, and somewhere in it a tiny little marker, a microscopic dot on a microscopic dot, which says "You are here" only went half mad and therefore just spends a lot of time complaining about how JavaScript would be better if it had been built on FORTH instead of Lisp with C syntax as opposed to the row of people whose brains all fully asploded.
brittle linden
The fundamental problem that makes side-channel attacks possible is the existence of side-channels. Running cryptographic code with access to keys on a general purpose CPU that shares resources with other CPUs guarantees that there will be side-channels. No matter how secure the implementers think their implementation is, it's just a matter of time before someone finds a side-channel and exploits it.

i think it might be difficult because the Windows API is not OpenSource, and given any single Windows application, is likely to also use some other APIs that are not also OSS, so you'd end up with a lot of "black boxes" that couldn't necessarily be filled in -- think of training on OSS and then trying to reverse engineer a VB app

Debian because I don't care about keeping with the latest and greatest, Plasma because... Well no reason I guess. It's just what's on the Steam Deck so I'm mildly familiar with it.
I don' tknow about any big updates.
Also funny thing about trying to get everything initially going, it turns out there's a conflict of some sort between Debian's choice of kernal, and the version of Nvidia's drivers in their repository. They don't seem to work.
Fortunately I was able to get around it by doing what everyone said not to. Specifically, installing the driver package direct from Nvidia.
Only other catch with it is that Nvidia's drivers don't work with Wayland, so the desktop is in Xorg. Which is fine. I'm not picky. It runs. My games run. I'm happy for now.

Maybe I should add some additional buttons for like.. pitch up/down
tardy badger
That’s why you pitch up/down lol
The sensor only has 7 inputs so I’m a little limited

What are those grid thing on the bottom?
tardy badger
What are those grid thing on the bottom?
Touch pads. They are grids to reduce overall capacitance and also make it easier to change the touch state. I may change it yet, just need to see how it functions

greetings, what is the resolution quality on the ultra tiny usb camera
in terms of megapixels
late fulcrum
640x480, 0.3 megapixels
raven tree
ah gotcha, thank you!
i dont suppose there is an all in 1 mc + camera combo with 8 - 12 mp
i know about the esp32 combos but the resolution is just not there
but i do like the size
rapid geode
at that point you are just buying a ... camera. like a blackfly or something.
raven tree
i already own a gopro similar to that, but i would like a similar camera but smaller and thinner
rapid geode
thats what a blackfly is. its a chip in a box with a usb (or serial or ethernet) port
they are a bit pricey cause they are industrial, but it gets you a lens mount, and all the features done for you
ah, neat. the adafruit one i guess is just a notebook webcam.

Ok, now I actually want a smartphone that is compatible with Milwaukee M18 batteries.
late fulcrum
That's a good idea
rapid geode
just put the phone inside the dewalt battery
late fulcrum
My old phone, I was considering using something like a tool battery, to power the phone, as well as a thermoelectric cooler and fan
rapid geode
if people were ok with a fatter phone you could use an 18650
would have the same or better battery life than what the lipos in phones now
late fulcrum
Fairly similar capacity

yup
50 grams. just fat
id have used ones in my nes controlelr design but its 1mm fatter than the case is ha

pretty much
rapid geode
if i did a gameboy type handheld it would get 2 18650's in it. 8000mah. would last days.
tardy badger
oh yeah, so true
rapid geode
we'll see. maybe ill sell a dozen nes one and can spend a few bucks on a screen
tardy badger
I get like 3 days of life out of a 2000mAh lip continuously monitoring temperature, pressure, ambient light, and proximity.

well the pi says about 190ma at load.
tardy badger
on an RP2040 which is notorious for slurping down battery like it's the latest fad drink
rapid geode
so 2 hours og gaming a say, it would last ages. week or more

technically speaking, you would probably be able to run a gameboy game on the likes of an RP2040

Wait, seriously?

1mA sleep without going deep into power registers
if you shut everything that you can off, 180uA
rapid geode
1ma sleep is 8000 hours with 2 18650s. haha
tardy badger
You can't get that level of sleep on circuitpython though with the RP2040
rapid geode
oh. speaking of. i need a power switch for my controller. where would you put it. i dont really know how the pi works in terms of on/off
tardy badger
I think the best I saw for RP2040 on circuitpython was like 5mA

How much memory does thr RP2040 have?
tardy badger
200k of RAM
and how ever much QSPI FLASH you put on your board
"""264kB on-chip SRAM in six independent banks"""
you can shut the power off to each bank independently
glad ruin
It should be able to run gameboy games easily then, assuming someone makes a fast enough z80 emulator for it.
rapid geode
there is an NES emulator for it (in the dvi demo)
so, the groundwork is there
but its not any smaller or much cheaper than a zero (at normal price)
late fulcrum
Should be able to emulate a Z80 plenty fast enough. Since the Z80 has a 4-bit ALU, it's not a speed demon
glad ruin
Yeah, the question is how efficiently can id do the instruction decoding?
tardy badger
there's already a gameboy emulator for ESP32
EspBoy
and there are... ROMs in the github repo untitled for your favorite... gameboy games
coughs
late fulcrum
The Z80 instruction set is somewhat gnarlier than the 6800/6500 chips, as it's a derivative of the 8008 series.
glad ruin
I'm sure it's possible, but Nintendo also likes to threaten people.

I wrote some Atari games, and toyed with writing Vectrex games. I tried to get the "black" PS so I could develop for that too.

There was an era where consoles were more or less GPUs built from discrete components. Sadly, we have now reached a point where consoles are literally just SFF PCs vendor locked to a subscription service. No more novel architectures.

The PS3 was the last of its line, alas
rapid geode
ps3 was a ppc right?
glad ruin
On the upside, this means that there is no longer any technical justification for console-exclusive releases. Does that mean the console wars and exclusivity deals are gone? No, of course not. Because people are stupid.
