The CatBot is an autonomous laser toy for your cat. You may say “But Joe, isn’t the laser pointer the best toy for the lazy cat owner?” I’d have to say no, the CatBot takes one step further. Using two servos, an Arduino and a cheap $3 laser you can provide your cat with endless […]
The Luna Mod Looper, basically lets you record a sequence using a potentiometer to control the pitch of the note, and then play it back and add affects. Ever since I saw videos of the Luna Mod being played, I wanted to build my own. However, the project required a picaxe microcontroller, which I have […]
In the kingdom of rock and roll it is important to set oneself apart. With millions of people in this world who can play the guitar, simply playing well is just not going to cut it. You need something extra to rise up as a rock god. Consider this guitar the mystical glowing ax bestowed […]
This instructable is meant to be a more complete explanation than others available online. Notably, this will provide more hardware explanation than is available in the LED Marquee instructable by led555. Goals This instructable presents the concepts involved with shift registers and high side drivers. By illustrating these concepts with an 8×8 LED matrix I […]
Bring out your 3D glasses and enjoy viewing in a novel way! I have added a new dimension to my instructable. If you do not have 3D glasses, then you can make one yourself. The following link explains how to make 3D glasses ( link ). Please Note: This instructable contains 3D images which are best viewed with […]
Who doesn’t love music? These Piano Stairs are an interactive, relatively portable, musical installation that can be applied to basically any stairwell. I built them for HackPrinceton and won 2nd place in the hardware track. I’ve had requests to share my code and diagrams, so I decided to make an Instructable! These piano stairs use […]
Make PPE milk bottles into good looking LED lights, and use an Arduino to control them. This recycles a number of things, mainly the milk bottles, and uses a very low amount of power: the LEDs apparently dissipate less than 3 watts but are bright enough to see by. Among other things, I wanted to […]
The DIY Cellphone is a working (albeit basic) cellphone that you can make yourself. It can make and receive phone calls and text messages, store names and phone numbers, display the time, and serve as an alarm clock. It connects to GSM networks (like AT&T and T-Mobile in the U.S.) using a regular (full-size) SIM card. It […]
In this project we’ll create a small add-on PCB containing the a MSGEQ7 spectrum analyzer circuit and show how it can drive the RGB LED cube kit from Freetronics. This allows the cube to display the seven bands over four horizontal planes. There is a small amount of assumed knowledge for this project – To save repeating […]
High speed photography is generally carried out in a dark room with dedicated equipment (controlled remote flash for example)… The instructable proposed here enables to make high speed photography outside (and enjoy the sun!), in less than 2 hours with some generic DIY basic tools. The principle is the following : A marble is dropped in a repeatable way. During […]
