Learning PID using ROS2 and Gazebo sim

For years now, I have been making these small projects (8 years since the first one!, geesh, I'm old), Here are some of them: * A face-centering gimballed Camera mounted on RPI * A hand-motion controlled DJI Tello Drone * At times, I use these projects to learn new

Reseting HIKVISION DS-2CD1021 IP Camera Password

Reseting HIKVISION DS-2CD1021 IP Camera Password

See Far, Go Further (HIKVISION's slogan. Me likey) I've been running my truenas server at home for a couple of years now. Initially, I used it for media streaming and peer-to-peer file sharing :). Later on, I learned about this app - Frigate NVR, and learned

Flash Tasmota Firmware to a Sonoff Smart Socket

Flash Tasmota Firmware to a Sonoff Smart Socket

As a vintage IOT enthusiast I used to flash my own ESPs with code I patched together in the Arduino IDE. My sketch would include WiFi and MQTT credentials along with a few "if then" instructions. I'd attach the ESP to a relay and configure things

Today I used Oscilloscope

Today I used Oscilloscope

Recently, I got a new board at work, with a new sensor (STM's latest). I've been tasked to write a driver for it to expose its needed capabilities to our application running on Zephyr. A decent task, not too shabby. When bringing up a board, one

How to Make the "Tip the Balance" Bathroom Scale

If you've decided to make the Tip the Balance Bathroom Scale, you won't find instructions here! (If you insist on making it, you can find the code here.) This post, on the other hand, will tell you how to make a working bathroom scale. List of

Garage Hobbyist Invents Device to let you Lose Weight in an Instant

Yes, you read the title right. No more arduous diets or cutting out snacks. No more exhausting exercises, or battling with feeble willpower. This amazing new device will take pounds (or kilos) off your weight at the literal blink of an eye. How many times have you stepped gingerly onto

The Essential Breadboard Tool that Nobody Has

The Essential Breadboard Tool that Nobody Has

How many hours in your life have you spent troubleshooting a project? Knowing your I2C from your SPI You've spent ages connecting a bolognese of wires on your breadboard, making sure to distinguish your MISO from your MOSI, your SDA from your SCK, your DIN from your SDA,

Hack together a dirt-cheap LoRa transmitter/receiver dev board

Hack together a dirt-cheap LoRa transmitter/receiver dev board

LoRa is relatively new in IoT. (Actually, not that new, but it's taking time to percolate into the ecosphere.) For those that don't know, LoRa stands for "Long Range." We all know the problem of putting a great little sensor at the foot of

Make an Astonishingly Minimalistic Multicolor LED Display for Pennies

A few months before Christmas, social media channels start filling with instructions about LEDs for home decoration. Popular software is WLED, a program that describes itself as: A fast and feature-rich implementation of an ESP8266/ESP32 webserver to control NeoPixel (WS2812B, WS2811, SK6812) LEDs or also SPI based chipsets

Make a Raspberry Pi Pico Oscilloscope with 3d Printed Case

Many readers of this blog will know that it's possible to make an oscilloscope/logic analyzer from the Raspberry Pi Pico. Called Scoppy, full details are on github. When I made a Scoppy with two resistors and a small breadboard a few weeks ago, I went looking for

Make a Weather Station with an ESP32 and a WeAct 2.13 inch EPaper Screen

Make a Weather Station with an ESP32 and a WeAct 2.13 inch EPaper Screen

This post is more of a Public Service Announcement that a real "how to" explanation. A couple of weeks ago I acquired a WeAct 2.13 inch epaper screen from Aliexpress. The price of such screens is falling continually, so they are now within easy reach of almost

Getting an IKEA Motion Sensor to work in Node Red

Getting an IKEA Motion Sensor to work in Node Red

I usually start my posts by warning readers that I'm an amateur with no background in coding or electronics. I write these blogs because while I'm figuring out how to do things, I'm working at ground level and my descriptions are generally simple enough

Today I made WALK UP! - The alarm clock that will walk you off the bed

Today I made WALK UP! - The alarm clock that will walk you off the bed

Hi there! my name is Elad and I recently joined the crew here on Whatimade.today. I'm happy to be here and I hope you'll enjoy reading :) I am an early riser and usually have no problem waking up in the morning. Yet sometimes, especially during

The Idiot's guide to making Volos Project's Beautiful Smart Watch

The Idiot's guide to making Volos Project's Beautiful Smart Watch

As I've mentioned so many times in my blog posts, I've never studied electronics or engineering. Consequently, I come at my projects entirely as an amateur - which means that when I finally figure out how to do something, I'm able to guide others like

Make a Remote Temp Sensor with Permanent Display inside your House

Make a Remote Temp Sensor with Permanent Display inside your House

Most of us use a phone app to see the temperature outside - which is fine if you don't mind receiving a reading from a sensor located at a meteorological station somewhere nearby. And when we finally do set up our own IoT sensors, to see them, we need

Connecting Switcher Devices to Node Red

Connecting Switcher Devices to Node Red

One of the first commercial home automation devices I bought was a hot water boiler switch from Switcher. Like most remote devices, it came with its own app. At the time - about 5-6 years ago - it was nigh-on impossible to hack into the protocol to connect to it

Today I made an NTP synchronized smart-lamp

Today I made an NTP synchronized smart-lamp

Ill keep it short. Since my last project, the smart-cloud-like-lamp, I wanted to learn how to use NTP synchronization. Time synchronization issues came up quite often while I developed autonomous drones back in The MakersPlace, and (surprisingly) it's also come up here at Augury'

Today I've learned how to use cement!

Today I've learned how to use cement!

I love scavenging for goods in my street :) You see, soon I'll start working more from home, so its time to make myself a proper office and stop lurking in my "laboratory": A few days ago, I've found this broken reading lamp while walking

Cricket Version 2

Cricket Version 2

Update November 2022 - it seems that ThingsonEdge didn't make it and the cricket is no longer available. Their web and social media presence have disappeared from the internet. Anyone with Version 2 can still update its firmware, but Version 1 - which updated from the ThingsonEdge server - can no

Learn how to use VSCode with ESP32 & Arduino

Learn how to use VSCode with ESP32 & Arduino

Hey All, This is a short manual I made while configuring VSCode IDE to work with ESP32 and Arduino on Ubuntu. Note: assuming VScode is already installed. * Download and install Arduino * Unzip the downloaded file (Say to ~/Downloads/ ). * Using terminal: cd ~/Downloads/adruino-<version>/ # Install sudo ./install.sh

Remote On/Off Switch for Blynk Relay - using ThingsonEdge Cricket, Node Red, and MQTT

Remote On/Off Switch for Blynk Relay - using ThingsonEdge Cricket, Node Red, and MQTT

Like most makers, my home is automated - not with off-the-shelf IoT devices, but with home-built switches and relays, Raspberry Pis and ESPs. My first remote switches - all controlled through ESP8266 01s- were mostly built with Blynk. I'd contentedly call up the app on my phone

Learn how to use doxygen

Learn how to use doxygen

In my previous post, I've described how I used design patterns for my TelloCpp driver. But, while project design is important - A project is nothing without proper documentation I always document my code, here's why: * It makes it easy to resume developing a neglected code * It

How to design a project from scratch

How to design a project from scratch

This post is all about project design. But before getting into UML's and other modeling tools, let us have a quick rewind: A few months back I went on a [recently paused] quest for building my own autonomous drone. This quest was quite pretentious I know. "I

Learn how to easily ssh into many Raspberry Pis without passwords

Learn how to easily ssh into many Raspberry Pis without passwords

This post was prompted by an exchange I saw on a RasPi Facebook group a couple of weeks ago. It started when someone asked how many Raspberry Pis members had. Scores of people responded, and it became clear that many of us have lots. One guy claimed to have 300!
