Christian Cawley spends a lot of time with Raspberry Pis and scours the web looking for interesting DIY electronics projects and news for ElectroMaker. He's currently trying to show his 7 year old son how to get to grips with Scratch, but so far to no avail.
DIY cameras are all the rage thanks to the existence of compact and affordable SBCs, but few have a real purpose behind them, beyond proof of concept. So what makes this Arduino Uno-powered camera any different?
We’ve all been there. You’re out and about, on a sunny day, when all of a sudden the clouds gather and it starts to rain. It’s not a light shower, either, but that apocalyptic type of rain storm that looks like all the rain in the world is going to fall before it stops.
If you’ve ever tried hooking up a hard disk drive to your Raspberry Pi, you’ll be familiar with the mess it can create. Both devices need a power supply; then there’s the USB cable from the drive to the Pi. Perhaps you tried using an external HDD housing; perhaps you prefer something more bespoke, like the Western Digital WDLabs PiDrive.
Ever wondered what happened to the Doctor’s robot companion, K9? The Time Lord’s best friend has made a handful of appearances in Doctor Who’s 21st century revival, but since 2010 he’s been notable by his absence on screen … (we’ll ignore the fact he was redesigned and given his own TV show.)
Doctor Who and Raspberry Pi-based projects go hand in hand. Both are British, and both have links to Cambridge (writer Douglas Adams studied there, and was Doctor Who script editor at the time Hitchhiker's Guide to the Galaxy hit the airwaves).
The whoopee cushion has been upgraded. No longer a rubber bladder filled with air (or, at times, a piece of foam), it has been enhanced and is capable of playing any noise you can think of, thanks to a Raspberry Pi.
Perhaps some sort of frame is the answer for your movie (or TV show, or pop group) posters ... and if it is, why stop with a bit of wood and perspex? Why not add a backlight, just like a poster found outside a cinema?
Looking for a totally new sound? You may have just found it. A couple of Google projects have collaborated to produce the NSynth Super, a Raspberry Pi-powered device that uses what has been coined “neural audio synthesis” to analyse the sonic characteristics of source inputs to create entirely new musical voices.
