This episode shows how to make a DIY Star Wars-inspired coffee table from concrete, wood, epoxy resin, and LED strips.
I combined Death Star style lighting with GFRC concrete, woodworking, and epoxy resin that is backlit with LEDs to make this Star Wars inspired coffee table. My goal was to design a DIY concrete and epoxy coffee table that every Star Wars fan would recognize as being inspired by Star Wars, but that non-Star Wars fans would just see as a cool table design.
In this video I create a color changing nightlight based on a famous symbol from one of my son’s favorite video games. Because space was tight, I decided to use an ATtiny microcontroller instead of an Arduino. These are very inexpensive and are a great way to shrinkify your Arduino projects. ATtiny come in multiple configurations (number of pins and amount of memory). One of the most popular is the ATtiny85 which only has 8 pins and is very small.
How about a Spider who obeys the order to sit, dances when he sees a light and dodges obstacles? All of this was assembled with just one board, the Arduino Nano 33 BLE Sense.

Despite the fact that making a hilarious yet not deceitful joke with a jack-o’-lantern on Halloween night is not unobtrusive, I decided to create an exceptional event for my guests on Halloween when they ring the doorbell by designing a jack-o’-lantern doorbell with intriguing features. And, not surprisingly, I only let some of my closest friends know about my new doorbell features by giving them registered RFID tags (entrance permits) to make my other guests frightened even a little bit 🙂 In detail, this doorbell talks to the guests and informs the user via WhatsApp when the guests ring the doorbell or show RFID tags or cards.
First of all, to make the doorbell talking with the guests after an interaction, I generated voices from texts for each occasion I wanted the doorbell to talk. You can get more information about how to create voice files over text files in the following sections.
The Engineering Octopus has launched a keyring with a difference: As well as helping you keep track of your keys, it doubles as a means to quickly test an oscilloscope — hence its name, the Oscilloscope Tester Keyring (OTK).
“All electronic engineers love to show off the fact that they are electronic engineers, and what better way to do that than with a keyring! Not only will the bare electronics be noticed by many, it’s also a fully functional oscilloscope tester,” The Engineering Octopus founder Max writes. “The OTK generates a pure, analog, sine wave (via a Colpitts oscillator) at approximately 10MHz (+/-2MHz). It has a DC offset, which allows you to test almost all functions of a oscilloscope, and carry it with you everywhere you go!”
Although the ESP8266 01 WiFi Module has a wide support and a good community crowd, the Arduino Uno board takes advantage of it’s ease of use and beginner-friendly layout over Arduino Micro for being one of the most used boards for cheap IoT solutions. As a result, there aren’t many tutorials documenting how to use the module with this board. So here’s a short & simple tutorial for people getting started with IoT and want to use the Micro+ESP01 combination.
Automated lightening of staircase not only helps to save electricity but also takes us to advancement in quality living of life. We generally uses normal circuit to turn on and off the light in stairs, but there is loss in electricity since we turn it off only at once during sleep. So, in this tutorial we are going to make the automated staircase that will light up only when it senses motion of people passing through stair.
Hello! Here is my game that I made for TTGO T-Display board. This board is based on ESP32, it have built in TFT display, and battery charger. It is perfect for making games. So here it is, space shooter game. I created custom PCB for this project. I used PCBWAY.com service, they have best prices and quality.
Here is code of game: https://drive.google.com/file/d/17jek…
If you are electronic or electronic hobbyist in general, you have probably used testing boards (or probing JICs) on occasion. These are often used to verify electronic boards or directly program them.
There are countless of them, from manual to fully automatic and you can easily buy them in countless online stores. However, our colleague Giuseppe Finizia decided one day to design and print his own completely versatile PCB Tester simply by using acupuncture needles, some cables and his 3D printer, cheaper impossible.
