isnt pakistan a us ally ? there no measures for exports of pc games or digital books to pakistan?

I totally get the frustration of shipping being slow and expensive

the market here for pretty niche stuff like this is pretty small plus a lot of people don’t have the income to spend on these kinds of things so it’s understandable that they wouldn’t want to spend all the money and make the hassle of it all

Id still look at the public library

I wasted money because I didnt realize my state library had all these electronics books for free

i’ll make sure to check that next time in there

they even have military ones so with a 36 class courses on electronic warfare from ships as well (not sure why) and janes stuff

and tons of niche stuff like building medical devices as well or optic fiber systems

violet parcel
#

Oh it's just the general principles physics

#

but still it ewxplains soviet systems in large details including how to use them if you had one (what the buttons do, the sub trailers etc) and for jamming it listed 8 methods with details

#

but seems to be public non-secret stuff. Not sure why 🤣

glad ruin
#

It was likely classified or at least not publicly distributed initially.

#

there are stuff like this at military college and to be cited when you do your thesis there

#

just didnt expect to see that in a general library thats all

#

just saying not good books to have on your desks like if the FCC visit you and investigate a possible ham interference or unauthorized transmission 🤣

#

I have a manual for a WWII-era tube tester that has a destruction notice saying to use everything at your disposal to keep it out of enemy hands (including TNT and incendiary grenades). Directly below those instructions was a warning about high voltages.

there is about 20 other ones too one of which uses practical examples from soviet equipment like I said

Some of those military training materials are quite good, they're aimed at making raw soldiers into technicians fairly efficiently.

Every time I want to do something with the pico+Arduino but all tutorials and libraries are for python...

late fulcrum
#

Yeah, the Arduino support for the RP2040 is poor, so many people end up using the earlephilhower core instead, but it's less "standard" and doesn't support as many libraries.

#

It reminds me of the early days of the ESP8266, where you had to custom build part of the Arduino project to support it.

fossil dawn
#

I'm using the earlephilhower core, too. 😄 My project will do a lot of audio stuff, which I think not that many people used yet. Because I keep running into bugs progress is pretty slow. But it's actually fun. So far he has fixed every single bug as soon as I could reliably reproduce it. And all my suggestions and small pull requests were merged too. 😄

quaint marsh
tardy badger
#

Adafruit added support in most every library they publish

#

It also works with display libraries like TFT_eSPI

fossil dawn
#

biggest issue with that core is imho, not enough people make bug reports. Like one I2S bug was reported months ago in an audio library. But it was actually in the arduino-pico core. Once I reported it with a sketch that reproduced it every single time, he fixed it within like a day.

#

But again, I really like it

#

does anyone know if the new rp2040 propmaker feather has a readable pin for battery voltage / charging status?

ebon dew
#

had family in town this week and they're leaving today. got my brother a macropad for christmas and he loves it. loading him up with some more stuff.

#

it's a Circuit Playground Express package stuffed with aligator to breadboard clips, Adafruit Circuit Playground Express, Adafruit ESP32-S2 TFT, 150mah Adafruit Battery, Stemma USB hub, 5 stemma cables, BME280 sensor, and a @balmy lotus Synthplug adapter for his Macropad. Good package.

#

@drowsy bramble Do you want to know the actual state of charge or just that a battery is plugged and on battery power instead of USB power? You can use supervisor to know if a feather is on battery or USB power on pretty much any feather. State of charge is a different story though.

#

It doesn't have a lc709203f or MAX17048 battery voltage monitor to my knowledge. You can probably monitor system voltage but there isn't a dedicated chip for it.

#

use usb_sense = supervisor.runtime.serial_connected to know if you're connected via usb serial which can also serve as a usb power notification.

# 
if usb_sense:
  # yes it's on usb power do something
else:
  # not on usb power do something else
#

if you always have a battery connected then the else would default to doing something while on battery power only.

#

otherwise it would just turn off 🙂

#

that only works if it's pc usb powered though since it uses a serial connection to the pc. if you power it from a wallwart then that kind of code won't do any good.

Hey all, if you were to configure an e-ink display once to initiate it, and then never touch it or refresh it again, how long would the display hold the text for without power? Also what's the lifespan of a typical e-ink display - years, decades?

fresh niche
late fulcrum
#

I've had eInk displays lying around for years, they're still readable

ebon dew
#

can communicate via i2c should be easy enough to integrate, it's another module though so will add size to a project enclosure.

#

they're fairly small so won't add too much space if space constraints are a concern. if space isn't a concern then it's a good option.

sometimes ya just can't squish everything you want on a feather 😉

oh wait, etchasketch? hmm

lcds dont really like magnets either

ebon dew

yeah but the gauss effect is just temporary where an e-ink might be a permanent flip

so the magnt actually ruins the panel?

#

not that i actually agree with the premise, but this store owner is blamed for a lot of food price inflation. so if you wanted to make a statement...

#

takes all the food poor people typically buy and make them 10 cents. and then take the prices of rich peoples food and raise it a little

ebon dew
#

still wouldn't change the barcode price when the register rings it up.

would only mess with the people and i'm not really in favor of that.

this store needs a kicking for a number of policies, even though that arent really responsible for inflation

ebon dew

everyone is responsible for inflation to some degree

rapid geode
#

yeah, for food up here, its kinda complex. the stores themselves only make a few percent profit.

#

also, theres a lot of games. there a rich and a poor store owned by each chain. and the prices in the rich stores subsidise the prices in the poor stores. so taking away their profits, or "fixing" them could actually make things worse for the poor

Sitting here wondering where my other stemma QT cable is though..

#

Anyway, I have this fun IO playground for the Cast-Away RP2040 boards I made

#

Currently it’s just printing out temp, pressure, and some data from the ambient light and proximity sensor

ebon dew
#

sounds fun, that's a lot of stemma ports

tardy badger
#

It’s for flexible connection. They’re mapped to pins that are i2c port marched for the RP2040. Helps if you are using other pins for other specific functions

#

You could also send UART over stemma qt if you wanted

i try to stay away from uart since i'm into graphics mostly end towards spi end of the spectrum, hopefully. doesn't always work out that way.

Lemme dig up my thermometer and see what accuracy it claims

This one is accurate to +/-0.2C

raw jasper

Medical thermometer says +/- 0.1C (within human body temperatures, not ambient!), and it costed about 10EUR. No idea what kind of sensor it uses.

The 0.2C accuracy is on the page itself, humidity is accurate to 2%

# olive dome From my personal experience with TMP117, the noise is quite low, definitely reco...

I'm talking about the noise of the sensing element itself. In the case of an RTD, there is wideband white noise that is directly proportional to temperature. It can be accounted for and managed to some degree. Semiconductor (diode) temperature sensors are different. They produce multiple types of noise and have to be actively driven by a current source, which produces even more noise. There's only so much compensation that can be done, hence the reason silicon based temperature sensing is limited to about ±1°C at the best.

olive dome
#

Again, from my personal experience, this is not the case for TMP117

glad ruin
#

Hmm interesting.

crystal ore
#

It's probably a distinction between noise and accuracy. If the noise is random, you can filter and average it before giving it to the output, even if the instantaneous reading is all over the place.

glad ruin
#

Yes. Presumably they are also trimming the crap out of those things in production to compensate for process variations as well

raw jasper
glad ruin
#

In fact I know that's what they're doing. By the look of it they test each one over the full temperature range on the production line and then programming a lookup table to compensate for any nonlinearities.

#

Normally these deals aren't so direct. Like in Canada the canadian govt paid air canada to land at regional airports so in effect they get bonuses for landing at them and offering service there as part of a financial aid package

#

But it's not like it's the airport (which are all operated by a non-profit in Canada) make a direct deposit on the airline bank account right after

#

They usually call it incencitive programs at smaller airport in the US. Like the indianopolis one : "The new airline Incentive Plan includes a mix of fee waivers and marketing support to aid in the attraction of new international flights, new domestic flights, new airlines to IND, and new international cargo flights. Simultaneous multi-city expansion benefits are available, and incentives will be provided on a first-come, first-served basis. The Incentive Plan has a financial limit of $1 million for the first year, that once met, will be suspended until additional funds are approved. "

ok indianopolis isnt a small airport but just an example of an actual deal. In their case they wanted to get back a indianopolis-paris route back

I had something weird happen back when I was interested in flight school. I had a discovery flight and they spent 1h of theory and 1h as the flight and for them it was the first hour of theorical training and the first hour of practical training and they told me it counted in the minimum hours to get a license. In that hour they talked about level flight and turning and how to use the radio if the instructor pass out. I was able to flight level and turn in the following hour but didnt want to land because I always crashed in flight simulator back then. But I thought it was weird the time spent was deducted from the time for flight school.... What do you think ?

So, you are mandated to have a specific number of hours of ground school and flight school.

It has a MIPI interface so you could do a raspberry pi zero 2W

#

Factor in optics

#

Probably could make a rough prototype for like.. $1500

#

Your biggest hurdles for making something comparable to the Vision Pro will be computing power, space, weight, availability of micro-OLEDs, and the extremely complexity of the level of sensor fusion done by the R1

#

And this is especially hard to emulate because of the R1 doing a lot of hardware level sensor fusion

#

Not sure how much I’d trust spending $90 but might be worth it

#

Comes with a driver board, neat

Wow thank you so much!

#

Do you know of any chip that comes close to R1

Maybe you could do it on an FPGA

You will need to do bare metal C programming, not using Arduino wrappers to get the speed and memory optimizations necessary to parse video data quickly

half plank
#

What is Metal C and is there a GitHub repo to look at.

tardy badger
#

Bare metal means you’re using Clang and writing all your code to be as minimal and precise as possible

#

It means talking directly to hardware registers and peripherals to improve speed and performance

#

It can be messy to get started

#

You like could get slow functionality in Arduino to start forming an understanding

#

But it won’t be fast

#

Though funny enough, you can do some register level operations in Arduino

#

Anyway, all this to say: it’s not impossible to make your own VR headset, just be prepared for the incredible monetary cost and the amount of time you will likely sink into making it.

# half plank Let’s start at the basics, how can I stream a video cam feed to a round TFT 1.69...

I know this doesn't directly answer your question but I'm not sure what exactly your're trying to do so just a suggestion:
FPV goggles like they're used for drones. You can get pretty cheap ones for <50€. They're just very big on your face.
Good goggles (still analog but using higher quality displays and smaller optics) can easily cost 400€. Just as a reference how expensive decent tiny screens and good optics are.
If you only need a small screen you could look into a "FPV Watch".
Regular analog FPV drone video transmitters just take an analog video in. You could use an FPV drone camera, or I think anything that outputs PAL/NTSC should work. If you use an FPV transmitter while stationary or even inside an enclosure, you might need to add a fan, as they're normally used on drones where the wind provides a lot of cooling.
This way you would get a very low-latency video transmittion without any programming. Quality is just, well, analog and not HD. And then you could of course add microcontrollers to the goggles or something for tracking movement or whatever you want to do.
Be aware, that using FPV transmitters might require a HAM Radio licence.

#

There are also ready to use wireless HDMI solutions for like conference rooms and such. But because latency is extremely important when you're doing VR I would try to remove the "transmit video" part completely. Like try to do the processing on your body or run a cable. Imho that project sounds already very ambitious.

I was playing with a color head mounted display option years ago when there wasn't much available for small high resolution displays. I figured I could basically miniaturize a CRT video projector, using a trio of 40mm viewfinder CRTs (one each for red, green, and blue) for each eye, and optically filtering and combining the images. Wearing six miniature CRTs on my head would have been somewhat bulky, but I was willing to put up with it to get 1024x768 full color video. Technology advanced before I got anything really working. I still have a dozen or so of the miniature CRTs.

I wanted to buy such a macro pad thing but all ready-to-use options were using proprietary software. I think there are self-built options but they're more work so they have to wait.

Have you asked what they are struggling with?

#

Perhaps there are some mental blockers keeping them from being successful

hasty quarry
#

I ask very frequently if there are any questions about what I just did, but I have a feeling they either have trouble articulating their struggles to ask good questions, or they just don’t want to communicate with me

tardy badger
#

For instance: feeling confident working problems as a group, knowing the next steps. But not having great self confidence

#

Self confidence can go a long way. I’d suggest working with this person struggling and trying to identify the areas causing the issues with confidence

hasty quarry
#

Their self confidence might be harmed because I have one student that catches my drift much quicker than the others and solves my problems very fast, which may discourage the others

tardy badger
#

I also suggest offering one on one office hours

#

Perhaps even requiring them visit at least one session a week

#

And also, instead of letting one person get ahead and solve all in class problems, have each student lead the problem solving so they can work on building confidence

hasty quarry
#

The problems are synchronous, I present it to them and give them time to solve it

#

It’s just one of them is way faster than the others

tardy badger
#

Try what I suggested for a few classes. You might be surprised. It’s a very effective technique.

#

At least for in class instruction and problem solving

It's also possible they have YouTube open in a second tab and just aren't paying attention to you at all. 😅

That way you can guide them if they feel unsure.

@hasty quarry In 1979 or so, I attended a 3-person grad class in the prof's tiny office, where one student would attempt to "surreptitiously" read the campus newspaper by leaving it out on top of one of his notebooks. I asked the prof about it at one point and he verbally shrugged.

I would assume military subs are more sophisticated. but maybe smaller manned ones?

dunno. i think the premise of the statement was that the $30 store bought ones made more sense than $100000 custom made things. even if the failure rate is very high, you just keep 10 of the on board

Wait why trouble some

violet parcel
#

we seems to have 5-6 questions a week about them and they seem to not get resolved

because first if you use an old board like an arduino you will need an sdcard to play the sound

#

and the 5-6 questions we get peoples just hear noises/static but not their .wav

#

and the .wav has to be in a particular format, correct cap and resistor etc

#

with a breakout these connections are already done. Personally Im eyeing the more expensive stereo version of lm386 with 6ohm speakers

I'm still wondering how it was even allowed to submerge

patent hemlock
#

there's no laws preventing it - the only thing that is remotely enforceable would be waivers and personal lawsuits

raw jasper
#

As far as I know, there are laws concerning the seaworthiness of (at least passenger) ships in most countries. I'm surprised no such thing exists for submarines

patent hemlock
#

my bet is on the waivers being ironclad ("they knew the risks")

#

it's not a "flagged" vessel

#

iirc

raw jasper
burnt tendon
#

There was the Libertarian Cruse Ship thing from a few years back that failed because there are actually a lot of cruise ship regulations you can't just avoid. Clearly they should have made a submersible instead, because that's clearly effectively the wild west.

#

But, yah, there was a whole thing that explained how it's not a flagged vessel therefore right now, there aren't many regulations.

#

There's a bad history of well-off people building their own submersible vessels. This is the first time someone imploded trying to reach the Titanic but there were some other past incidents.

#

Dono. I've always wanted my own submersible. Like, unrealistic poorly engineered childhood dreams wanted. Clearly it's a good thing that I've never been in a position to try, although a ROV might be fun.

Honestly, what I probably really want is just a James Bond Villain Lair with a shark tank and my office can be in an acrylic bubble underneath the shark tank. Then again, there was that giant fishtank with an elevator in the middle in Berlin that blew up a year or two ago.

Plus the known complications of sharks with lasers on their heads accidentally taking out me instead of my opponent because... acrylic bubble.
