Want to play Pong on your computer with your Esplora? This example shows you how. This example is designed to be used with a Processing sketch. Processing is an open source programming environment. The Esplora reads the slider and buttons and sends data to the Processing sketch serially over USB, and Processing uses the incoming […]
Time for something different – a single button combination lock. Allow me to explain… Updated 18/03/2013 Normally a combination lock would require the entry of a series of unique numbers in order to unlock something or start an action. For example: A more contemporary type of lock could be controlled electronically, for example by a

Spirometers are the classical instrument to perform the parsing of air as it is blown out of your mouth. They consist of a tube that you blow into that records the volume and speed of one breath which are then compared to a set of normal values based on height, wt and sex and are
There is no amazing story behind this project – I just always liked the boxing machines, which were located in various popular places. I decided to build mine! Step 1: Designing In the beginning, I designed a 3d model of my device. Boxing pear, frame, case and additional parts. Based on the dimensions of this
The Knock Box is a power strip with superpowers – it turns on your lamp whenever you knock on your nightstand. You get two outlets, individually controlled by knock-knock-knocking on a nearby hard surface. It’s great for hitting the lights when it’s pitch dark, but if an appliance can plug into the wall, you can toggle it!

Recently I was reviewing one of my oldest project, and decided to “refresh” previous design by taking full advantage of the new arduino Leonardo board. Based on AtMega32U4, which include PGA (programmable gain amplifier), oscilloscope’s analog front end doesn’t require external OPA this time, end could be build in 1-2 hours on prototype board, using
Hi guys, we will make an interesting project in this project. We will try to make a flame by snapping our finger.Let’s get started on the project. Step 1: Video Tutorial You can see the project step by step with this video tutorial. For the first time, I will explain this project by speaking. I
Here comes a simple Graphic Equalizer showing 14 audio bands from 60Hz up to 16kHz. It consist of a PCB based on MSGEQ7 and ESP dev board. Since a MSGEQ7 chip recognizes 7 bands only and an ESP dev board gives us a chance to read a single analog input only, there was a trick
The Pi is a fine little computer board, though not nearly as good as the Arduino when it comes to I/O capabilities. The beautifully-engineered Gertboard is a plug-in add-on that neatly overcomes this deficiency by giving the Pi access to an ATMega328, but it’s a very complex and expensive solution. An alternative would be to interface
My project is to make a heel (shoe) that senses when your foot is tired and then eases the pain. I will have a force sensor measure how much pressure is on your foot for 3 minutes. If the pressure is at a certain measure for 3 minutes, then a vibrator will go off and
