When a Wi-Fi device is switched on, it starts spewing out probe requests to try and find a familiar access point. These probe requests contain the device’s MAC address and the SSID of the hotspot it’s looking for, which can potentially be used to identify a specific device and where it’s been. After experimenting with these probe requests, has created… [ 205 more words ]

“By designing around a 10mm x 44mm LiPo cell, I’ve been able to add Wi-Fi connectivity, a USB connection for charging and programming, and a dangerous (but intriguing!) overvoltage mode.”
Space Buck’s Double-Oh Battery Board Packs Power, Wi-Fi Control Into AA Battery-Size Form Factor
https://www.hackster.io/news/space-buck-s-double-oh-battery-board-packs-power-wi-fi-control-into-aa-battery-size-form-factor-ab3670bbd779
Offering power, charging, and controllable voltage output via a Wi-Fi interface, the Double-Oh Battery is a real powerhouse.
Pseudonymous engineer Space Buck has released a new power supply board in the same form factor of an AA battery, with integrated Wi-Fi support for remote control: the Double-Oh Battery.
“This is the spiritual successor to the SMOL, a tiny PCB that interrupts battery output to make fun patterns,” Buck explains. “By designing around a 10mm-by-44mm LiPo cell, I’ve been able to add Wi-Fi connectivity, a USB connection for charging and programming, and a dangerous (but intriguing!) overvoltage mode.”
“The star of the show is the ESP32-PICO-32, a 7mm-by-7mm powerhouse. It handles the wireless networking and various GPIOs. The original design used the ESP8285, which is like the ESP8266 but with 1MB memory built-in.”
Full details can be found on the Hackaday.io project page, while the design files are available on GitHub.

Replace Your IR Remote With A Web Browser
https://hackaday.com/2020/10/28/replace-your-ir-remote-with-a-web-browser/
While more and more consumer products are rushing to include WiFi and Bluetooth connectivity, the simplicity and reliability of infrared has kept it in the game in the game far longer than many might have thought. Despite being thinner and sleeker, the IR remote control that comes with your brand new smart TV isn’t fundamentally different than what we were using in the 1980s.
But that doesn’t mean IR devices can’t enjoy some modern conveniences. Sick of misplacing his remote, [Sasa Karanovic] decided to come up with a way he could emulate it to control his TV over the network. Now with nothing more exotic than a web browser on his phone or computer, he can tap away at a visual representation of a remote to control the TV from anywhere in the house. As you might expect, this project could readily be adapted to control whatever IR gadget you might have in mind.
The hardware for this project is little more than an ESP32 development board and an LED
ESP32 WiFi Remote
Make a WiFi controlled remote using ESP32 and couple of additional components. Complete how-to guide and a detailed walktrough is available at YouTube.

An Open Source IR Gateway Based On The ESP8266
https://hackaday.com/2020/10/14/an-open-source-ir-gateway-based-on-the-esp8266/
The market is absolutely inundated with smart gadgets, with everything from coffee makers to TVs advertising that they support the latest and greatest in home automation platforms. Don’t worry about how many of those platforms and services will still up up and running in the next few years, the thing will probably stop working before then anyway. No sense worrying about the details in a disposable world.

Hi everyone! Here is a new upgrade of my Smart LED Matrix based on ESP-01, now it is controllable from the internet, I can change the displayed text and its colors, I learned to communicate with an Adafruit server and then create a small mobile APP so I was able to create a friendly interface for its control, here I show you a tutorial in which I explain how I did it: https://www.instructables.com/DIY-INTERNET-CONTROLLED…/

Code Your Own Twitch Chat Controls For Robots — Or Just About Anything Else!
https://hackaday.com/2021/04/08/code-your-own-twitch-chat-controls-for-robots-or-just-about-anything-else/
Twitch Plays Pokemon burst onto the then nascent livestreaming scene back in 2014, letting Twitch viewers take command of a Game Boy emulator running Pokemon Red via simple chat commands. Since then, the same concept has been applied to everything under the sun. Other video games, installing Linux, and even trading on the New York Stock Exchange have all been gameified through Twitch chat.
You, thirsty reader, are wondering how you can get a slice of this delicious action. Fear not, for with a bit of ramshackle code, you can let Twitch chat take over pretty much anything in, on, or around your computer.
It’s Just IRC
The great thing about Twitch chat is that it runs on vanilla IRC (Internet Relay Chat). The protocol has been around forever, and libraries exist to make interfacing easy.
SimpleTwitchCommander, as I’ve named it on Github, assumes some familiarity with basic Python programming. The code will allow you to take commands from chat in two ways. Commands from chat can be tabulated, and only the one with the most votes executed, or every single command can be acted on directly. Actually getting this code to control your robot, video game, or pet viper is up to you. What we’re doing here is interfacing with Twitch chat and pulling out commands so you can make it do whatever you like. With that said, for this example, we’ve set up the code to parse commands for a simple wheeled robot. Let’s dive in.
SimpleTwitchCommander
https://github.com/whatuptkhere/SimpleTwitchCommander
A simple IRC scraper to command robots, games, or anything else by reading Twitch chat. With Python!
Can be used to take direct actions (as in “LIGHTS”) or to take a democratic vote on commands (as in “FWD”, “REV”, “LEFT”, “RIGHT”) as shown in the example code.

PiNet — One Small Project Grows Unexpectedly
https://hackaday.com/2021/06/25/pinet-one-small-project-grows-unexpectedly/
A few years ago, [Gregory Sanders] aka [Dr Gerg] had one simple wish in mind when he started what is now the PiNet project — to know whether his garage door was open or closed. Instead of searching out off-the-shelf solutions, he looked at the project as a learning opportunity. After picking up Python, he built a system from a Raspberry Pi, a 12V gel cell battery, and a power supply / charger circuit. Thus project Overhead Door (ohd) was complete (see the ohd GitHub repository) and [Dr Gerg] was done.

Astronomic Patio Light Timer
https://hackaday.com/2021/06/30/astronomic-patio-light-timer/
Not satisfied with the handheld remote control for his outdoor patio lights, [timabram] decided to build an automatic timer using an ESP8266. He’s using a set of string lights from Costco, but as you dig into his project you’ll see the method he uses can be applied to almost any set of lights that have a remote.
He does this by connecting GPIO pins from the ESP8266 GPIO into the remote control in order to simulate a user pressing the button. Both boards are packaged together in a 3D-printed enclosure that utilizes the front portion of the remote control, so that manual operation is still possible.

Building a DIY Smart Doorbell
https://buzzert.net/posts/2021-05-09-doorbell
In my last post about DIY smart appliances, I wrote about thermostats. Chipotherm has been running for over a year now at the arcade, and it’s still working great! Armed with enthusiasm for my DIY smart thermostat, and having just moved into a new house that came with a Ring doorbell, I thought I might try building my own DIY doorbell to replace it.
