Designing hardware logic circuits can be fun. The old school way to do this was with NAND gates, on a bread board, wired up with jumper wires. This is still possible, but it doesn’t take much before the number of gates gets out of hand. A newer option is to use an FPGA (Field Programmable […]
A few years ago, I became a dog owner for the first time. I didn’t like leaving Cody in the kennel alone all day. I had a webcam on him, but I couldn’t watch it all day long. What if he was in some kind of distress? What if there was a emergency at the
Can you believe that we live in an age where you can touch an object (any object – if it has metal on it) and a light will turn on in your loved-one’s space – even if they live in a different city, state, or country!? You could tell your loved ones or friends when

When I say simple, I don’t mean use a speed control. But control the motor directly without any external circuitry. Here’s how: How this came about: I recently was working on an instructable about charlieplexing with an arduino. And I was wondering if the same principle would work with motors to some extent. So I came
These are step by step instructions for assembling the 8×8 LED Board kit from moderndevice.com. I had never played with LED displays before using this kit. I suggest reading through all the assembly steps BEFORE starting to solder because assembly order DOES matter with this kit. Overall, this is a very simple assembly. It does
A few months back, I posted an Instructable on my Raspberry Pi movie player tucked into a VHS cassette. Since then, I have built several for friends and family, and have simplified the process. Using a Raspberry Pi v3, we no longer need a USB hub and no longer need to remove the GPIO. This tutorial requires
The project This project follows on from the excellent work by ScotSEA and his Arduino reset program (see http://www.instructables.com/id/CatGenie-Resetting-a-SaniSolution-Cartridge/ ). I had never taken my Catgenie apart as Scott did, but had built a small contact board instead. I had previous updated Scott’s program to so that it output some debugging output to the computer

Although it is great controlling the robot arm with computer or mobile phone, I think using joystick is also cool, so I’ve bought a joystick shield and make a new project. This joystick shield is compatible with Arduino. It also support Nokia 5110 LCD module, nRF24L01 wireless module and Bluetooth module. It should be fun
My Ninth Project: Robot Arm with Joystick Shield using Arduino Continue Reading
Beat Sync is a single frequency audio spectrum volume meter. It can isolate around a certain frequency ( I choose the bass ) and display it on a creative 8 segment LED bar graph. This is meant to be quite simple, yet allowing room for more difficult upgrades. It is built around the Arduino Open
It’s been a long time since my previous tutorial, my work is quite busy and I spend less time on Instructables. This time is a project that I like very much since my first saw it on Kickstarter: Air Bonsai. I was really surprised at how the Japanese made it, really a beautiful and mysterious piece.
