@Ayaan Brantley shut up you other bot

Loool :) Jeff - please let us know when pi5 will be on its way.....xD

I thought the same, but in the datasheet. "1 × Timer with 4 alarms, 1 × Real Time Counter"

Pico have inbuilt RTc ?

And SWD stands for 'Single Wire Debug', not 'Serial Wire Debug' ;) source: am using it everyday atm

@@artvandelay777 In the RP2040 datasheet it actually says real time clock at the start of chapter 4.8.

@@henriburau6293 Yep. I noticed that after I posted. "Real Time Counter" is from the pico datasheet.

baby life lol

I'm hoping for the same!

ESP8266 provides a serial AT interface to Wi-Fi from the factory and costs $2. $3 if you get one with 3.3V regulator on a breakout board. If you need the GPIO capabilities of the Pi Pico it's still cheaper than most options to just wire an ESP8266 to one of the Pi Pico UARTs. That also takes the burden off the ESP GPIO. Where that could be important is a heavy interrupt environment. Like driving a long bitbanged SPI bus full of LEDs. If you change the LEDs based on callback functions you can find the WiFi interrupts on the ESP preempting your interrupt handler beneath the Arduino app in FreeRTOS because it has realtime priority. What that looks like is a bunch of scrambled LEDs toward the end of your string. For example, a Phillips Hue protocol app that changes the led strip to a solid color will kick back a HTTP 200 response to Alexa the instant the callback returns and potentially scramble your SPI data. If the Pi Pico is driving the LEDs and the ESP is only doing WiFi this problem is easily solved. You don't even need to bitbang SPI on Pi Pico. You've got like 4 separate buses. This thing is an IO beast, really. Anything similar in a single chip, like Teensy, is likely to cost way more than $4 or $7.

@@AugurIliKur Don't bother with the ESP8266, the 96KiB of SRAM isn't enough to do TLS crypto over the internet. It's only useful for connecting to device locally hosted on the same LAN/Wifi segment. Look at TTGO's T8 board for a good inexpensive ESP32-WROVER module with the 8MiB PSRAM. Worth it for $6, and you can do TLS connections, even SSH2. www.aliexpress.com/item/32851423415.html *NO NEW DESIGNS* should be using plaintext protocols past 2020. I'm seriously so sick of warning people off eWeLink and onto tasmota+nodered on a pi. HomeAssistant makes things much easier to deal with, without the ornery cloud connection nonsense. It *IS* possible to get an 8266 talking TLS1.1 in software, but you have to dick around with nginx/apache buffer sizes. It will NOT work with the default 16KB buffers -- you need to drop it to 2KB or 4KB. This also means that it's a nightmare trying to talk to JSON endpoints on existing infrastructure using the defaults, which are not under your control to be able to change. You're just straight up locked out of those. As an example -- take a look at the Lichess client.

It’s meant to be embedded into a larger project board. It would be be hard to add a WiFi chip if you really need it, just grab a spare serial connection.

@@GrahamCantin Depends on the use case. E.g.. I can't see why Internet radio must be encrypted. And although the ESP8266 is limited, I have been logging in to Google to get my mail headers and unreadcount using OAuth to login for 2 years now. No dicking around apart from the required dicking around with OAuth. Also here, depends on the use case. But I agree, the ESP32 is a better choice in most cases, just bought 10 ESP32 modules with 8MB PSRAM for 21 dollar on Ali Express ( alsoavaliable at Mouser and Digikey for similar prices)..

Ah yes lets go to the ROOM TEMPERATURE

can't feel my pants

People always dismissing the value of documentation and support then wonder why companies don't put more effort into docs and support lol.

It’s weird that you say that when this has less software support than most anything else out there right now.

@@Hornet135 I really relate to what you said because I was a victim of that myself (had to make my own I2C LCD library for it in C because there were only ones for Python), but to be honest the documentation for the SDK and the hardware itself is really good

That's what I keep thinking to myself. ESP32, all the Teensy boards, now this? We are truly spoiled for choice.

You could probably harvest enough thermal energy from that infant humaniod to run the sensor and wireless node that monitors it's preferred storage temperature...

Wouldn't be more efficient to make one core run doom and the other one process VGA signals?

Doesn’t have the ram

Someone (SparkFun?) already has a little handheld emulator in the works 🤪

@@JeffGeerling I guess whatever program state or variables you declare you have goes into RAM (including emulated NES or whatever ram) and what’s on flash is what a PC emulator process in ram looks like after an NES ROM is loaded but before emulation has begun. I’m just spitballing here. Embedded development is weird. Edit: I guess with 256kb you COULD be able to arbitrarily load some of the smaller 32k NES NROM games into RAM - Mario 1, Excitebike, and have enough for a frame buffer. Uhhh....

@@johnsimon8457 you can hook up an external RAM chip

@@charetjc well, it's not a coincidence that the world population exploded only 100 years ago

I know right?!

@@user-xr3rb6pn9m I'm not going to try and claim that the reduction of infant mortality rates isn't a significant factor, but there's also just the way that population curves work involved here.

I have a small board the same size as an ESP01 that plugs in and allows it to be powered and breaks out the usable pins. I have it wired up to a DHT22 to monitor temperatures. I also have a variation that has a couple of individually addressable LEDs for indication purposes. For this kind of thing, I'd probably use a PIC though.

And if you do that temperature project with analog components, you'll need 2 op amps (in 1 IC) and some resistors, and it will cost less than 1$, and most part of power consumption will be on LED :) Transistors will do that job as well, but you'll need to spend much more time on tuning.

​@@user-pf5ov8sn5lI absolutely agree, but with blue pill and Arduino IDE + DS18B20 it will take an hour or so - comparable to RPi Pico or even less. Including searching for (almost) ready code, because programming blue pill under Arduino IDE is far more popular than RPi Pico. I just want to say that blue pill is more common, more tested and a way cheaper. I don't get what is the niche for this product. "Normal" RPi was stunning project, with MMU that enables to run full Linux with very low cost. RPi Pico has nothing special to offer.

@@megastarling Agree. And (if you didn't that yet) take a look on black pill - it based on STM32F411CEU6 - 100MHz Clock, 512kB Flash, and 128kB RAM, USB-C interface software accessible, 32 I/O, including 14 analog inputs - almost the same, will do the same job for +/- same price - 4$ from AliExpress + 1$ delivery to Ukraine (and btw, you'll never get Pi for 4$, because of same reasons - VAT, shipping, etc).

@@user-pf5ov8sn5l Thanks, I will definitely look at it. Params looks very promising.

@@danielh6219 depends on what you do. Software support is great for those, but they have less processing power (though that probably doesn't matter to too many people. 72MHz is plenty for a lot of things.) If you want multiple cores though, I don't know of other boards in the same price range.

@@coreforge esp32 devboard has dual 240mhz cores + additional ultra low power core, supports wifi and bluetooth connectivity, and costs about 4$ on aliexpress

@@nikitoss1108 Yeah, noticed that too. I haven't done much with ESPs in general and haven't looked into the ESP32 since I didn't need wifi for anything.

@@coreforge esp boards looks nice if you write high-level code, but if you try to dive deep into low level coding and write timing-critical things, then better to use another hardware, cause espressif are not so good at writing datasheets

I'd definitely use C since I know it already but they are all real programming languages.

Thank you!

He has a few GPIO pins left. Should be able to squeeze out a nightlight too. LDR , resistor and an another LED.

@@mikehensley78 I think Red Shirt Jeff might have had a 'blowtorch as a night light' idea brewing.

@@CFWhitman if the room got too cold the blow torch could ignite and warm it up. it would also need an RGB LED for style and horsepower.

Probably a green blowtorch, a blue blowtorch and a red blowtorch, hmmm sounds like a nice idea.

The one good thing about the Pi distributor network is the stores all charge the list price ($4). The one bad thing about the Pi distributor network is "out of stock" is a common refrain :(

@@JeffGeerling Unfortunately for hardware I think 2020 and 2021 will be "Years of out-of-stock" in general.

I drove over to the MicroCenter store in nearby Marietta, Georgia and bought a couple Pico boards for US $2 each. It was an introductory promotional price.

Just use an ESP32-PICO...?

You'll love this channel.

5 seconds is good to have for moving average, especially with sensor inside the chip, it can jump a little or you breathe on it and it would jump too much.

I mean what about a door or a window left open? :D (just sayin' ...)

Sure, but if the energy cost of reading the sensor isn’t exorbitant, why _not_ update it that fast? Power still has to be flowing to keep one LED on and run the timer that’s counting the 5 (or 30) seconds.

Yep i get it i get it! In the particular scenario it make sens. But if it was an app notification you may want to have a faster feedback to avoid temperature drop. TLDR: Temperature can drop quickly that is just what I wanted to say.

@@glamax1393 I mean its not like temp down for a minute = baby dead. And I think in a scenario like this a delay of even a minute wouldnt be all that terrible. And sudden drops in Temp in a flat are ussually caused purpoasefully, like opening a window. I get what you're saying, but I think what another commentor mentioned is more important. The Power of the Leds may aswell be much higher than the measuring.

Yes, then just wire the switch into the board externally.

*CLACKING INTENSIFIES*

Writing your own dedicated OS independent interactive RGB effects doesn’t sound like too bad of an idea.

@@TheRybka30 Yes, it seems so.

I bet they plan to have one very soon. Most likely the chip will go where the R Pi logo is now.

@@coda821 I have no idea. Lmao. Why you askin me?

Pff... try running Cyberpunk properly.

There are many use cases where a lack of WiFi/BT is a feature, and not something missing. But the Pico has board space... I can imagine a Pico W someday for $10 with WiFi/BT support.

​@@JeffGeerling sorry Jeff, but WiFi/BT can be easily disabled in the code, so as long as uC module costs the same or less it does not matter. Also I wanted to mention that STM32-based Arduino Nano-like boards are quite popular and cost less than $3 on AliExpress, so at this price point competition is very hard, which is good. And also IMHO Python is not what one should really use for uC programming. Thanks for vid anyways

@@user-pk8fr8ix6d disregarding ability to run python seems very similar to someone saying a board without wifi is a feature. Its a tool, you can use it or not depending on the needs.

​@@JeffGeerling $10 Pico W would be much higher priced than esp8266 or even comparable esp32 dev board. Only way your comment about your argument for lack of Wifi on board is valid argument if you could show case that the power usage is much lower even with Wifi disabled on esp32.

​@@maciejurbanski6146 thanks for the explanation. How could I miss that I can use or not Python? I think that's why there was 'IMHO' word.

Why? Celsius is even worse. At last Fahrenheit puts one end roughly at body temperature and has roughly 4x the revolution.

@@SmallSpoonBrigade "roughly"... always a good thing when it comes to measurements... How about something repeatable, yet very common and easily understandable... like, i dont know, the freezing point of water...

Friends in the states can mail you some in a birthday card.

for what purpose would you need anything more than a cheap usb 2.0 on this little thing? I'm half doubtful, half curious btw

I agree for most thing, but for a microcontroller, why? Micro-USB cables are still cheaper, more common and with a microcontroller, once it's connected, it stays there for a long time, you don't connect and disconnect it every day like a phone, a tablet or maybe a controller.

@@araarathisyomama787 I just hate the connector, I lost a few gadgets and phones due to the poor reliability of it, I know that you're probably using the connection twice (to program it and power it and leave it doing its function) but other than a couple of pi nanos/esps that I bought like 4 years ago I don't want to come anywhere near another micro b cable/connector, with just data+/- and 5v/gnd is really cheap to implement in the same way the micro usb is in this one

@@MrCed122 how much cheaper are they? 50c/cable? I get that this is not going to be plugged and unplugged as much as a phone or any tech gadget but I find micro b really inconvenient to use and going forward is going to be less and less used together with type A, having to look for an otg adapter to plug in a type A-> micro or find a weird micro->C cable in a couple of years when most laptops will probably drop type A is gonna be pretty annoying, my first type C phone is from 2015 (OP2), other than to literally save a few cents in production and to have a slightly smaller connector I see no point for it to exist in 2021, even at this price since you could raise its price to 5 or 6$ and it would still be sold out everywhere for the foreseeable future, it's probably compete with the 0 pricewise too much but it's for a different use case

You can also buy an esp32f401/f411 board with type C for $3

Arduino nano knockoffs are so cheap they are still viable if you just need a simple microcontroller. It's about 2 euro on Aliexpress.

The nano has definitely less features than this device.

If you think an 8-bit AVR MCU is in any way shape or form comparable to a dual-core 32-bit ARM MCU for any other reason than to point out how they're nowhere the same ballpark, this discussion is not worth having.

Ok fine, its ARM, but still, i dont see a point using this over lets say ESP32. What am I missing?

@@AttilaAsztalos If an 8 bit micro is sufficient for your hobby project, I think they should be compared. The example in this video could be made with a nano to prove the point.
