This example shows you how to read analog input from the physical world using a potentiometer. A potentiometer is a simple mechanical device that provides a varying amount of resistance when its shaft is turned. By passing voltage through a potentiometer and into an analog input on your Arduino, it is possible to measure the amount of […]
Another quick hack. I purchased a voice changer because I was looking for something cheap that could be hacked into an voice input device. Basically I wanted to animate a skull when I spoke. Added bonus, now the skull puppet would also have a scary voice. I am going to show you how to hack […]
UPDATE (8/29/13): Thank you readers for your enthusiasm and kind remarks regarding this project! It has been a tremendous journey since I started this project back in March, but I am very glad with the resulting product and the excitement with which it has been received by the maker community. Happy building! -Cyrus Do you like […]
This instructable will guide you through the process of making your very own star-cluster from LEDs and acrylic. I made this piece for my electronics final project at college and had access to a machine shop. This instructable assumes that you have access to similar tools. This project was very much inspired by http://www.instructables.com/id/working-progress-n-how-to-make-a-multilayered-a/#step8. Step 1: […]
Lite Brite pegs look like LED’s don’t they? That’s what I though the other day after working on an LED cube for a few hours. I happened to see my daughter’s Lite Brite sitting there, and I looked at the pile of LED’s on my desk. What a perfect match! In this instructable I will […]
Make a 3D interface using an six resistors, aluminum foil, and an Arduino. Take that, Wii. Update: a much more thorough explanation of this project is available from Make Magazine. It might be easier to follow their instructions, and I think their code is more up to date. The basic goal here was to make […]
How to make an “analog” input device from fabric and a few other necessary materials. “Analog” in parenthesis because, although it is made up of 4 analog inputs, the only analog transition between the directions (up, right, down and left) comes from the buffering material (in this case 3cm thick squishy packing material) that absorbs […]
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 […]
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 […]
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 […]
