Impressed by these two LEGO® Dragster sets, a 250 pieces LEGO®TECHNIC Dragster 8847 (released in 1983) and a 391 pieces Top Fuel Racing 5533 (released in 1999). These two Dragsters inspired me to build my own LEGO® dragster, the “12 Thumbs”. The name “12 Thumbs” came after I finished the design. While I was playing with my finished […]
Do you want to build a robot that is in an invisible enclosure? Or have you wondered how the robotic lawn mowers stay in their garden?In this Instructable I will show you how you can easily build a perimeter loop yourself.This perimeter loop uses a filter named matched filter. This filter allows us to recognize […]
After a break of around two decades I’ve recently started building a model railway. One of the issues I’ve faced is trying to work out how fast I should be running the trains so that their speed reflects reality given the scale at which they are modelled. I’m guessing the details won’t interest everyone reading […]
In addition to gambling, dice (die – singular) are used in many board games, e.g., Backgammon, Monopoly, Yahtzee, Liar’s Dice, Dungeons & Dragons, Trouble, etc. Common dice are usually white with black “pips”. They are sometime known as d6 or D6. In this Instructable, the results of a simulated toss of a die (i.e., a […]
The Strandbot is a DIY upgrade for the Strandbeest originally designed by Theo Jansen. Strandbeests are amazing mechanical creatures that are able to move on their own using just a little bit of wind power. Unfortunately my tiny apartment is short on wind, so I decided to upgrade a miniature Strandbeest using an Arduino and […]
In this Instructable, I’ll show you how I managed to create my own I2C controlled device that I can then connect to any microcontroller and interact with it over I2C. In my case, I’m using it to control an AC dimmer module from a separate Arduino Nano and I then interact with it from another […]
This project will show you how you can create your own programmable thermostat with temperature probe, an LED readout and ability to remote control outlets. The core of this project is actually a driver for a 4 digit seven segment display. There are lots uses for such a device. You can purchase something called a PID […]
One of the projects in Practical Arduino is the “Online Thermometer”, which combines an Ethernet shield with a number of DS18B20 1-wire temperature sensors to allow you to read multiple temperatures and make the values accessible using a web browser. In that project I chose a specific model of Ethernet shield that was available at […]
In this IoT project, I have shown how to make an IoT-based Home Automation with Arduino IoT Cloud & Alexa using ESP32 to control 4 home appliances with voice commands. If the internet is not available, then you can control the home appliances manually with switches and IR remote. During the article, I have shown […]
General purpose Arduino shield for self-balancing machines. Why did I make it? I previously made an Instructable in 2010 on how to build a self-balancing skateboard. http://www.instructables.com/id/Easy-build-self-balancing-skateboardrobotsegway-/ There are >500 comments on this and many express confusion setting up the balance sensors, software and electronics. On top of that, the analog output inertial measurement units […]
