Think about your microwave or mobile phone. How easy would they be for an average consumer (or perhaps even you), to repair? Very difficult – in fact, stickers on many appliances note that there are “no user-serviceable parts inside”. If you have an iPhone, you’ll notice that it uses special, rare screws that it’s difficult to find a screwdriver for. Even the battery is encased within the phone and impossible to replace without serious intervention.

There are some legitimate reasons for this. Microwaves, for example, probably discourage users from fiddling around with them for product liability reasons – if a user tries to repair their microwave and injures themselves, a small appliance manufacturer wants to be able to say that they told you not to mess with it. But there are also lots of reasons why you should be able to take apart, and perhaps then modify, the things you buy. Continue reading “Making Things Maker-Friendly”

MMMM: Monitoring Motion

Eyes!

That time is once again upon us! This coming Monday, October the 10th, is our second installment of the Monthly Monday Microcontroller Madness series!

 

This month’s workshop will feature the concept of motion sensing in relation to microcontrollers. We’ll be taking a look at passive infrared sensors (PIR) for motion detection, ultrasonic range finders for distance measuring, and even looking at how to integrate a webcam into your Arduino project for motion analysis. These sensors and techniques are great for adding to your Halloween projects (wink, wink).

 

In addition to talking about motion, we will be offering our usual advice and guidance to those currently working on projects, or looking where to get started. All skill levels are welcome and we look forward to seeing you on Monday!

 

UPDATE: Here’s a link to the Arduino Reference page for the Parallax ultrasonic sensor and a code page for the Parallax PIR.

Manufacturer information can be found here and here, respectively.
