This is so cool! Not even that expensive to make.
So it became clear I can't hear jack shit if I'm playing games with my headset on. So with a PI0w and super cheap voice detection board, I wrote a python script that sends a push notification to my phone via Prowl if my kid wakes up crying (or a pin drops).

The remix of the soundtrack they use in the video is awesome too.
edit: The creator is on Reddit if you have further questions! Just message him at /u/AllenMPan.
I've been a huge fan of the RPi 3A+ because it is: (i) cheap; (ii) has a really nice set of connections (full HDMI, USB, headphone) and 5Ghz Wifi; and (iii) more minimal power draw than the 3B+ or 4.
I don't really understand why this article doesn't compare the 3A+ to the Zero 2. According to this review, the 3A+ is pretty much the closest to the Zero 2.
It's a bit sad how the 3A+ is often forgotten in its utility.

Raspberry pi subreddit is a good starting point as they are used to output to the display.
Here is a tutorial how to do an Equalizer with a 64x64 display:

There was a family who set up a huge house wide automation that had its own blockchain currency for chores, etc. that could be spent to watch Plex, game console time, or gift cards I believe. Hugely overkill but the father was interested in learning blockchain.
If interested, I also published a project tutorial, including instructions and code files:

Thanks for your comment. Yes, you are right, the pi alone can handle reading an analog sensor with an Analog-to-Digital converter such as MCP3008. But, in this project, I wanted to cover the topic for beginners - how to read analog sensors with Raspberry Pi via Arduino. So, Arduino is not a necessity for replicating this project but only an AD converter.
In my following project, if interested, I cover how to read analog sensors with an AD converter - MCP3008.
ooo, have you ever seen the OpenCat project ?
Looks pretty cool with similar stabilization and personality tech. Personally out of my price range but I’d love to make one some day.
That's not an x-ray of a raspberry pi. It's a layout view of a voltastream zero. https://www.hackster.io/news/the-voltastream-zero-a-raspberry-pi-zero-lookalike-for-digital-audio-c5e740a2cbc9
/u/nomoreimfull ignore this post, it's a red herring. An engineer that values their time would absolutely try and see what happens when they cut up a $5 board.
PYNQ is your friend here, I am literally just working on a hackster project which shows how you can use PYQN and openCV to test out your algorithm. Then you can use the XF:openCV / Vitis Vision libraires in HLS to accelerate and run them through the hardware.
Creating new overlays is actually simpler than creating solutions which are going to use Petalinux.
I did a recent PYNQ course which is available for free online the link is here https://www.adiuvoengineering.com/post/microzed-chronicles-free-virtual-workshops-on-demand
The project I am doing will be on hackster in the next day or so, there are several other image processing ones there as well my channel is https://www.hackster.io/adam-taylor
I built something similar: https://www.hackster.io/cameroncoward/featherquill-34-hours-of-distraction-free-writing-bf522b
It uses an LCD, but you could swap it out for the Waveshare 6" (you'd just have to figure out the software side, like they did).
This project very likely emulates keyboard key presses.
I made something similar for my daughter for homeschooling a few weeks ago. a very basic mute/unmute button.
I used a tiny Arduino and followed an online tutorial.
Check this out, complete with cases, batteries, and 2 year operation on a CR2032 battery.

Started with reading Grek Tinkers project description but mainly based on this one https://www.hackster.io/hodgestk/traffic-camera-9d3739. Just a few changes, such as only save images if the standard deviation of measurements is below 12. Camera on a 1metre flat extension mounted to look down to road from top of window to reduce glare and reflections (headless pi in a fanless heatsink box on top of kitchen cabinet). Added usb wifi to pi4 and disabled on board radios (seems to make USB3 to SSD more reliable plus allowed a high gain aerial to improve connection).
Mosquitto mqtt added to first pi with LAMP server to save readings in mysql. Grafana added to server to serve charts via Apache2.

I made a small beginner EPS project with the NodeMCU ESP8266 chip to turn on my PC. The nice thing about this set-up that you don't need skills or third party apps that can have compatibility issues. The major advantage against wakeup on LAN is that you can turn off your PC this way and you can turn on your PC when it is completely shut down.
This is the first time working wit an ESP8266 compatible board and it was surprisingly easy. I made a post on the project in detail if you ae in to the specifics. https://www.hackster.io/Seafox_C/turn-on-your-pc-with-alexa-and-the-esp8266-like-ironman-572b7b

AWS Rekognition is insane. Took me about 2 hours to use it to ask Alexa to determine if I left the clothes on the clothes line in my backyard with image recognition. Like 98% accurate. https://www.hackster.io/xelfer/bring-in-the-washing-b40fba
> Spotifyd also supports the Spotify Connect protocol which makes it show up as a device that can be controlled from the official clients.
I can sense a new Raspberry Pi (or other SBC) project on the horizon... Oh wait, something similar has already been done, but in a less-integrated manner.

But all that work to get just a single lane? Their USB3 implementation is pretty good, and if it did not meet my needs I’d probably look at something else. That said, hacking is fun so why not?
there's a ton of open source options out there that you can build on -- probably easier to start there. most projects run using analog sensors connected to arduino / raspberry pi / both. Hydruino is one example. Hydromazing Smart Garden System.
it's easiest to create a LAMP type data structure to record and log sensor inputs to a database so that you can dial in your settings for each aspect. there's also tons of smaller, one-off projects too on github for things like a smart outlet for a dehumidifier, etc.
I don't know why you'd want to start from scratch unless it's just a pet project though. good luck anyways!
Here's the walkthrough on my new shoulder-mounted robot familiar: https://www.hackster.io/glowascii/archimedes-the-ai-robot-owl-325ff5

For those of you too lazy, I've compiled a quick table of rough total cost of the materials.
You can find all the materials here: https://www.hackster.io/hackershack/smart-bartender-5c430e
Going through the links on Amazon they provided, for the majority of the hardware components (no tools included):

Momentary Push Button Switch | 2 | $15.96 |
PVC Project Board | 2 | $15.96 |
8 Channel Relay | 1 | $9.59 |

Total | $301 |
At this point, I wish Martin would just dash the entire all-in-one ego destroyer of a monolith machine and just focus on smaller, separate instruments that each provide only one aspect to his compositions. He's shown to be adept at this with his lovely Modulin.
If branding and viewer excitement is a concern, these new instruments could be simple enough for the audience to actually follow along, slowly turning the viewership from one of passive second-guessing to one of active making and performing. It's much easier to hack together a working Modulin (https://www.hackster.io/davy_j/digital-synth-modulin-wintergatan-inspired-ab2b83) than it is to even do a price analysis on how much a MMX would cost to make.
Not only does he get to spread the final musical project over more performers, each instrument will have clearer constraints, smaller scopes, and (much, much) faster turnaround time while keeping with his lovely DIY aesthetic.
Wintergatan Live is more than one person and I bet all his usual collaborators would be interested in taking a custom tool in hand to make his next body of musical work a unique reality on stage.
If you already have a Raspberry Pi 3/4, this project costs around 30-40USD depending. You end up having an internet-controlled robot that you can drive around or let your friends and family "visit" you from anywhere in the world.

This is a fairly easy task for the pi. You can connect a button to a GPIO and ground pin, and write a simple script that monitors for a button press. The basic idea: https://www.hackster.io/hardikrathod/push-button-with-raspberry-pi-6b6928 Depending on what you are connecting, you will need a relay, transistor circuit, or motor controller because it likely won't be able to be powered from the pi. Your script can be set to run when the pi boots so it is always running in the background.
You can build your own for close to $5 if you want more control. The dash buttons are neat, but I find that the detection isn't perfect, and I often miss presses. I'm (slowly) working on my own to allow for some basic error checking, handling multiple buttons and different press sequences (e.g. long-press, double tap).
Hackster.io has numerous project ideas. For example, the Smart Doorbell is an excellent introductory project requiring both the Alexa Dot, Raspberry Pi and a few inexpensive electronic items forming an useful home utility while exposing you to fundamental tools, skills and learning experiences.
Good luck selecting and working on the project you select.

Good job! I have always been fascinated with home automation stuff
I would like to suggest that you add some more modules before launching the kickstarter campaign.
I have also made a home management system which allows you to control you home through a website and uploaded it on hackster:

I have a question, will this be an educational product, or a real product that I can install at my home?
If you have any open cuts/scratches it can sting but you cover those with some Vaseline and then it won't.
I built one and like it very much but am also looking at upgrading to a professional device like Dermadry for convenience.

I really enjoyed my first play with a pi. It was a little nerve wracking as I’ve never used Linux before.
Heh, you know, it does, but REALLY BADLY :) Basically, to save battery (and it gets good battery life for the size / what it does), then the thing sleeps when you're not using it and the firmware it comes with doesn't try to bother being a watch during that time. So it forgets the time every time you wake it up. Putting the clock on there seems like it was a jokey afterthought. If you can code for arduino, you could mod the firmware, but eh.
tl;dr: not in a useful way, that ain't what they made it for (annoyingly)
--
EDIT: I read further! It actually can't, has no RTC (realtime clock) chip! THAT'S why they didn't support a proper clock! hah! (again, that ain't why they made it ;) )
--
EDIT2: Some crazy fucker made a firmware that IS a clock... by getting network time from a time server on a wifi network! But this is just insanity. It would only work as a clock while near wifi it had credentials for, AND (I believe) it can't do its network-attack thing with this firmware. It is, however, hugely geeky/interesting if you like that sorta shit. https://www.hackster.io/hague/esp-wifi-timeserver-synchronized-wrist-watch-8940cd
I record each machine separately to be able to fine-tune the volume levels between them. But I don't change the pitches. The devices really play each note you hear.
The programming part is a bit complicated to explain but "microcontroller" and "stepper motor" are some of the keywords here. I use a microcontroller to control the speed of each stepper motor. And they create sounds with different pitches at different speeds. You can read more about the idea here.

Do yourself a favor and go with a BME280 sensor. The DHT22 sucks. http://www.kandrsmith.org/RJS/Misc/Hygrometers/calib_many.html
IMO running an rPI per sensor is way over the top.
ESP32 comes with WiFi and BT support, and might eventually support BLE mesh. It will drive your sensors just fine.
nRF51822 modules might be another option worth investigating. I have no personal experience with these, though.
It's an IFTTT recipe I found a few years ago. It has an accompanying bash script to capture the speedtest-cli results then sends it to a google sheet on your account. I've modified it a bit to send the captured data to my webserver. Can't exactly share atm as I'm at work.
But if you really want it now, you can probably find it on google using the keywords "ifttt speedtest logger". The one I found was a tutorial article. I already forgot what website it was, though I think I have it bookmarked on my computer at home.
Edit:
I did a quick google search and I can't find the article I've found before. Though the IFTTT recipe is still alive here. The link to the bash script is also in the recipe description.
Edit2:
Sorry. I think I found the article I'm talking about here

So can the ESP8266 be used by itself, i.e. w/o a arduino or other microcontroller?
Also, I think it would be neat if it could be used to host a captive web server so that people could connect to it and see a cached version of befairbevegan.com, goveganworld.com, watchdominion.com, etc.
I usually start with understanding what sort of industries I want to be in and look for potential automation projects. Below are two references that I use for inspiration.
Book: Automating the Boring Stuff with Python
If you're not scared of a little programming, I was using NodeMCU's running some simple C code in Arduino Studio with sensors, then updating over a MQTT network and graphing in node-red. Pretty much this
https://www.hackster.io/13699/autonomous-weather-station-with-esp8266-90f8b3
Great entry point if you're a beginner.
Your biggest problem here is secondary processors talking over each other. The master-slave paradigm exists to ensure that no two devices are talking on the shared line at the same time. Triggering an interrupt on the main device is the least of your problems.
Edit: Here's an example of a multi-master i2c setup: https://www.hackster.io/chipmc/arduino-i2c-multi-master-approach-why-and-how-93f638
You'll likely need something of this complexity to do what you want, media access control is not a simple problem.
It certainly isn’t easy on the scale that I do it on our website. Takes a lot of wiring and programming to pull this off. However if you would like to make a small version of what I do and let people control your lights via twitter, you can see my write up on hackster.io build time only takes a few hours and he code is copy and paste to get it working.

I worked on an indoor room tracker for my dog using cheap beacons and some custom firmware. All available via MQTT and visualized in Grafana. Project link. This is what the visualization looks like.
I did something like this a while ago using openhardwaremonitor to do the legwork of reading the CPU stats and a small C# application to send it to the arduino over the Serial interface.
It was a while ago so I don’t have any details saved, but this is an example: https://www.hackster.io/zakrzu/arduino-pc-monitor-66c07a
Why? Because I could!
It ended up being a pretty fun "retrofit" exercise that involved some data collection up front and the use fo Edge Impulse to build and iterate on an image classification model. Full writeup is here: https://www.hackster.io/brandonsatrom/monitor-the-analog-world-with-tinyml-fd59c4
Google cannot dictate hardware standards. Qualcomm Snapdragon, Exynos, MediaTek and Kirin need to join alliance with ARM to bring hardware standards in their SoCs.
Raspberry Pi is the first one in the race : Raspberry Pi 4 Strides Towards ServerReady Status via SBBR-Compliant UEFI Firmware Effort
What Google can do is to comply with hardware standards in their own SoCs. Mobile hardware desperately needs generic drivers. Only maintainers of Postmarket OS are working on generic drivers for their OS. Some of the android phones are running mainline Linux kernel because of that.

Instead of a dog, what I have is a custom rasypberry pi security system. Cameras.
Outside my house, the cameras watches for movements and if they detect something, a cheap display in the house turns on showing what was detected, and snapshots are saved to the cloud. The screen turns off soon as no more motion is detected to save energy.
Inside the house... Facial recognition. If someone that's not supposed to be in the house gets picked up by one of the cameras, alerts goes off. I get texts and emails. Alerts also gets set off if too much motion is detected in the house when my face haven't been detected in a few hours. Videos are saved to the cloud if alerts are set off.
https://www.hackster.io/gr1m/raspberry-pi-facial-recognition-16e34e
It's always relaxing for me to work on my security system... Upgrading it. Maintaining it. Checking for fails. Testing.

I used template matching in this project, so it does not need any training to detect villagers. Therefore, it can run successfully during four seasons by adding templates from each season.
Nope, not QMK. It just runs a really simple CircuitPython script on a Raspberry Pi Pico. The code leaves a lot to be desired (because it's based on delays). I've written far better code for other keyboard projects. But this was just quick and dirty, so I didn't care much. You can find full details here:

its not mine unfortunately. i came across it on a instagram post, and tracked down the site they pulled the image from https://www.hackster.io/news/type-quickly-in-comfort-with-this-diy-chorded-keyboard-d3c4a3ace3f2
The price differs depending on PCB manufacturer service fees. I used PCBWay, but you can download the Gerber files here to try it with your manufacturer.
Yes I have and I have a training course on it also. You do need to use the right version of the tools. A few other gotchas
1) make sure Keil is the right version and the ELF file is actually updating
2) if you placed and routed the design make sure the MMI file is up to date so it puts the program in the memory correctly
You can find a link to the class I have created here (oddly this class has been very popular we have taught it to about 1000 engineers, at conferences and online)

there are some projects also here on hackster
Passive tracking is usually done with cell tower triangulation and WiFi SSID mapping. Here's an article on it.
Look at backup solutions for photographers, there are quite a few:
Alternatively, DIY. Old smartphone with a simcard and a usb cardreader might be enough. Or if you're really adventurous:
5V output is standard from the fast charger. The phone has to make an explicit request for higher voltages explained here.
Project sites like Instructables and the Arduino project hub have more complex projects. Search there for projects that match your interest.

By converting the neural network model I built into TensorFlow Lite or Micro, you can create a handheld device with microcontrollers such as Arduino BLE Sense.
You can inspect my model here.

For now, I want to build a breakout type game using sprites. To control it, I want to use a potentiometer and an analog to digital converter. Eventually I’d love to build this into a full computer with a DIY keyboard. I find this project very inspiring for its form factor and built in keyboard.
