This is the display at my local coin car wash and I like the unique style and color. Does anyone know how to identify the part number or find a similar display?
Hello, I hope this post is ok in this subreddit - since it's a little bit promotional of a product I designed. Though, I genuinely think it might be helpful to some, particularly those planning to make LiPo/Li-Ion & solar powered projects and want extensive power management and monitoring features. I posted about this board some months ago in r/esp32, it's called the ESP32-S3 PowerFeather. Last month it was finally available for purchase.
Since then I’ve been working on a demo web app that lets users explore some of the features of ESP32-S3 PowerFeather, which I recently got to a decent state:
The web app is served from the ESP32-S3 PowerFeather (acting as an AP) and is accessed from the tablet's web browser. The part encircled in yellow shows the battery being charged at 1.5 A from the solar panel at the set MPP voltage of around 12 V.
The web app also displays other supply & battery telemetry information as well as some power management controls which are all built-in into the board and accessed using the PowerFeather-SDK API.
For those interested in the demo web app, maybe to try it on their PowerFeather or just to see how this was created: https://github.com/PowerFeather/powerfeather-demo.
Hello Reddit,
I created a tutorial on SSH into Raspberry Pi from external networks! By the end of the video, you will be able to control and program your Raspberry Pi from any WiFi network using SSH protocol!
https://www.youtube.com/watch?v=guJR7-33N2k
This is a great tutorial for beginners or people who want to develop remote applications with their Pi. I think you can learn something quite useful. I think you can learn something quite useful.

Hi,
Could you share information about the implementation cost of UWB or BLE solutions for asset tracking in the industry?
For example: UWB - 3k tags, 2 factories, 10 anchors: $50k + $5k annual fees.
Thank you :)
Can anyone recommend a free IOT basic training that would help me progress in my knowledge online?
This is a very specific question sorry about that. I want to automate something for my girlfriends business and I want to essentially trigger the brother QL-1100 label printer to print labels using python or node.js. But brother makes this really confusing it seems like there is only and SDK for iphone or ipad? I have literally no clue how to get started reading the "documentation" if one could call it that.
Does anyone by chance has done this before and could tell me how I just get started?
It would save me a lot of pain, thanks in advance :)
Hi IoT gurues.
As a disclaimer, I'm new to this, so this might be a stupid question.
Im having some gateways from that i want to use to transmit sensor data from some Bluetooth devices to Azure over cellular communication. I think i need some certificate files to make this work, but i dont know what the easiest/cheapest solution might be? I have included a picture of the configurator for the network of the gateway. Can you smart guys give me some advice or a direction to go in?

Hey there,
My friend needs assistance setting up IoT devices at home without compromising the security of his personal devices. These devices should solely access the internet for firmware updates and essential services. With a spare Raspberry Pi and a tablet at our disposal, we're unsure where to begin. Could you offer guidance on the hardware, software, and configurations needed? We're aiming for open-source solutions to minimize expenses. Any recommendations or helpful YouTube tutorials would be welcomed. Thanks in advance for your help!
It's part of my research project. The plan is to simulate an IoT attack in a controlled environment and then implement defensive solutions to counter such attacks. What simulation platforms are available that can be used for such demonstrations? It can be any kind of attack on an IoT device/network.
Hi. I'm new here. Just wanted to ask if anyone has worked on mapping local mosquitto with cumulocity Iot? I have a trial account and wanted to test my local devices(running in mosquitto via mqtt) on it They have a microservice called 'dynamic mapper' which perfectly fits my use case but adding a microservice is not supported in the trial account. Also, how was your experience with the platform?
In my experience, the platform is indeed good but their customer support is subpar unfortunately. I tried reaching out to them for a week and they only responded after I posted on the forum.
Hello, I have a logger(using esp32 ULP) which sends data over wifi 3 times per day and am looking for a battery for it.
The thing is I would really need help in choosing a small form factor battery with a large capacity of +15Ah. I was set on the ers36415 but is large in diameter (~3 cm) even though I love the 20Ah capacity.
Is there any other way to go for my constraints?
Thank you!
I ideally wanna average the color pixels on my monitor and send it to the RGB lights to help with atmosphere while I game. Kinda lost in what brand to go with, I've got a raspberry pi ready to go but I'm also foreign with the tech. Any guidance would be appreciated!
Edit: syn == sync
Wondering if anyone here can help me:
My company deploys weather stations to farms that send data over the Cellular IoT network. We've discovered this year that some old weather stations we have no longer work with modern SIM cards. In discussing this with Bell Canada we were told:
"In order to deploy your existing 3G modem, you would need to insert an older sim card that is SMS format SIM OTA. You can identify if the card is SMS format or HTTP format by the marking on the card. The HTTP format card is marked with “BTM10046” or “JDTxxxxxx”. The SMS format card is marked with “BTM100xx” where xx is a number LOWER than 46."
Bell no longer has any stock of the SMS format SIM OTA cards. Does anyone know where I might be able to source them? I only need about ten of them. I am located in Saskatchewan.
I‘m looking for a device where I can trigger from code running on my mac the print out of labels we use in a vintage clothing store. Never worked with label printers before, if you have experience with these apis I‘d be glad over advice.
I guess we just want to be able to print out various QR codes that correspond to a product id and some additional information like the price (maybe separately).
It would be nice to have flexibility around what we print out (like can I pass it a pdf or so to print in the right format?). And to trigger maybe print out different stuff under certain conditions in the code (maybe sometimes only the price for example).
No clue if that can be done.
Thanks in advance for any insights!
Hi, I am just wondering whether I can manually change the values on the Y-axis or if it is auto generated.
Is there anyone here who has experience with this series of IoT RF modules? Interested in helping/consulting us with issues we are experiencing? Sierra support is close to nonexistent.
Thanks
Dear all,
I'm working as a research assistant in a thermal lab and I'm trying to see if there is a way to automatically download iButton (https://www.mouser.sg/new/analog-devices/maxim-ibutton-devices/) data to csv files. The thing is that we have a lot of the iButtons data and it tends to be a bottle neck.
Does anyone have any idea how can I go about it. Was thinking of programming a software to do it automatically.
Hello,
Looking for help selecting a simple POE cam that I can use to monitor some other hardware components.
I've tried ordering these small ones off amazon but they did not seem to work without their special app, and many people had issues according to the reviews. https://www.amazon.com/Revotech-Camera-Indoor-Security-I706-POE/dp/B096VK398F/
I've also tried the m5 PoE Cam, but it seems more complicated than my needs with the requirement to burn the software on it before it would work.
Are there any good small PoE cams that will simply work when connected to a network so I can stream locally?
Appreciate if I can get some product links to lorawan gateways
This is the requirement so far
Support 5G outbound to internet
Supports configuration to Azure IOT hub with vendor step by step documentation
MQTT protocol.
Price <$800USD
If there are any important details I can provide to establish recommendations, let me know.
PCB section of the W5500 ethernet segment
I made 20 custom PCBs with W5500 ICs for IoT stuff.
I've tested them all on multiple different types of networks and they all got a working link and DHCP handshake with the LED indicators blinking, even when directly connecting my computer to it and it not receiving a DHCP.
The issue is that on one industrial switch (which has PoE) the link is not being established at all. This is the first time this happened. Even disabling PoE on that switch the link will still not turn on.
Can anyone guide me to help me solve this issue?
Attached are the schematics and top view of the ethernet section if it is of any use.
I've just stumbled upon on LoRa so I don't have any deep knowledge regarding this topic so before I dig into this a bit more I would be grateful for an answer to my question - is it possible to use LoRa technology to connect two devices without a gateway? Will this allow to send data between these two devices the are located around 500m from each other in the urban area? If not - what would be an alternative in your option? I do not need to send a lot of data - let's say 100 bytes is max, speed is not crucial.
Can anyone in the community recommend a standalone 4G camera (Like a Reolink Go or Arlo Go2) that supports SGP .02 (M2M profile) rather than the consumer SGP .22 standard that the two cams I mentioned support?
I have seen all of the individual pieces needed for this project but the scope, pipeline, and implementation are a mystery to me. Google results are a cesspit of dubious marketing claims as soon as "AI" is a search term.
Any credible resources on this?
proof of concept would be an AI assistant of any kind synced to a speech synthesizer and lip animator on an avatar.
Getting it to display on magic mirror with a module would not be the hard part.
I’m new to IOT but recently saw that the Qualcomm QCC730 gives wifi capabilities at an 88% reduction of power usage.
This may be a silly question but is that a big deal? If yes, what kind of new capabilities does it allow for that weren’t possible before?
Thanks for any insight.
I'm making solar powered IOT device and I'm not sure if LIR2032 can be connected just like normal lipo battery pack.
As I understand, it's just lithium ion battery in coin shape. But then I'm not sure how solar power manager would think about it.
Any advise?
I am studying Information Systems and we have been given an assignment to do any IoT project of our choice. We were never taught how to do such or have an experience in it.
