Had a quick look round at turning a piezoelectric speaker in to a sensor that will detect a tap or knock. I also then had a search around for setting the output of a speaker to a different note. Combining this has given me a small basic Arduino drum machine and a headache to my […]

Microchip doubled the throughput and quadrupled the memory of its 32bit PIC family, and released a tool which brings third-party firmware into the firm’s integrated development environment (IDE), as well as adding new peripherals. Most of the up-grade has come from replacing the original MIPS M4K CPU, as used in the most recently announced PIC32MX […]

A friend at work proposed a friendly competition between a few co-workers: to make something cool out of a Trader Joe’s green tea mint tin.  Anything – whatever our creative hearts desired.  The prize?  Nobody cared – we’d figure that part out later. I thought it would be fun to do something electronic with it […]

The BMP180 is a new generation digital barometric pressure and temperature sensor from Bosch Sensortec. In this tutorial, we will briefly review this device and describe how to interface it with an Arduino Uno board for measuring the surrounding temperature and pressure. We will also discuss about retrieving the sensor altitude from its pressure readings. Experiment setup […]

Data analysis coming soon! My school is kind of strange. We don’t have a cafeteria, but we do have a four week course on “The Simpsons.” We don’t have a jungle-gym on the elementary playground, but we do have a half-buried firetruck. We don’t have a football team, but we do have a bee-keeping club. […]

Took me a little while to get started but I’ve managed to wire 2 PIR infrared sensors with an Arduino to sense motion either on the left or on the right side. The result will trigger an LED to represent each PIR sensor then I also added in a servo to be controlled – so […]

This example shows you how to answer a HTTP request using an Ethernet shield. Specifically, it connects to pachube.com, a free datalogging site. The example requires that you set up a pachube.com account, as well as a pachube feed (for more information on setting up an input feed, please click here). Your Ethernet shield will […]

We copter hobbyists love RC FPV flying, and we have seen a lot of awesome FPV videos taken by professional and relatively large multi-copters. But It doesn’t have to be a big quadcopter or RC plane to do FPV. I recently looked into a cheap and light weight FPV solution, and I found a couple of […]

There are a lot of things this world needs at the moment.  One of them is a better mouse trap.  Mice are getting smarter every day and if we’re not careful we’ll end up with Planet of the Mice.  Luckily, with the help of a Makerbot Replicator 2 (its enormous 410 cubic inch build volume […]

So having worked out that I can make a remote for my Nikon D80 to do some timelapse photography. I started thinking of things I can do to trigger the remote, below video shows it working but you’ll need sound to hear the shutter going. First of all check out my tutorial for making the […]
