Fresh hacks every day
[Chonggang Li] wrote in to share a link to the final project he and [Ran Hu] built for their embedded systems class. It’s called Piano Hero and uses an FPGA to implement a camera-based touch screen system.
All of the hardware used in the project is shown above. The monitor acts as the keyboard, using an image produced by … Read the rest
[Rohit Gupta] wrote in to share this touchscreen piano project he built around the TI Launchpad. It provided a way for him to explore using a resistive digitizer found on a lot of mobile devices. These are simply stuck to the top of LCD screens and replacements are inexpensive, but salvaging one from old hardware is an option as well.… Read the rest
We mourn the loss of the physical keyboard with the advent of tablets. After all, we do a bit of typing getting all of these features posted throughout the week. And we kind of blame tablets for the decline of the netbook industry (we still use a Dell Vostro A90 when not at home). But we’re trying to keep an … Read the rest
When [Andrei] first got his Raspberry Pi he wanted to make it a standalone computer right away. This means the normal input devices like a mouse and keyboard, but also some type of display. To avoid waiting for shipping he ended up using a cheap vehicle backup camera screen from the local big box store. It worked great, and recently … Read the rest
[Andrei Istodorescu] has been hard at work building a 7″ touch-screen rig which runs XBMC. It may be upside-down, but the Raspberry Pi board which is front and center is still easily recognizable. There’s a lot of stuff connected to it in order to pull this off, and even more software configuration. But as you can see in the … Read the rest
[Christian] wrote in to tell us about his third-generation Arduino MIDI sequencer (translated) called the AM808 VX3. He had already laid a strong base for the project in his previous versions. But the user interface was still frustrating at times and that’s where this version comes in. it features a nice clean dashboard like interface, but also includes … Read the rest
eBay isn’t only about counterfeit designer handbags and boxes of all-marshmallow Lucky Charms, sometimes there’s actually something useful for sale. [Matt] found a bunch of Chinese-made ARM development boards with integrated LCD displays on the ‘bay, but without a reliable toolchain, these boards – as cool as they are – are nearly useless. Thankfully, he figured out how to do … Read the rest
