Accelerometer, that tiny workhorse

Accelerometers are wondrous little devices that offer boundless possibilities… as soon as you figure out a need for them. For some time now, I have been thinking about a filament break detector for 3D printing. Filament comes in spools of 400m (1 kilogram) and they are usually hung on racks …

Single input, multiple output power source for a variety of needs

Sometimes you have a need to power a few devices while using your Arduino. For me, this situation arose when I was building my 8mm film scanner. I have to power the Arduino, a light source, and the Canon IXUS 95 camera I use to shoot the pictures. In theory …

The 8mm film scanner (Telecine) project, part 5 – Programming

Last time, in Part 4, I described how the Arduino is wired with the two servos, two switches, and the hacked Canon camera. Now, it’s time to pass through the code of the Arduino and show you how easy it actually is to get the Arduino to power your projects. This flowchart …
