Tiny-TS: Just How Small Can A Playable Synethesiser Get?

The early electronic synthesizers were huge machines, racks of electronic modules that filled entire rooms. Integration of electronics over time successively reduced them, first to the size of a large piece of furniture, then to  tabletop consoles, to standalone keyboards, and to small MIDI black boxes taking their instructions from…...

Fripon is French for Meteorite Hunting

Just a few weeks ago, we reported on a US NASA project to track the path and estimate the size of meteoroids in the sky using a distributed network of a handful of cameras. It turns out that there’s a similar French effort, and it’s even cooler: the Fireball Recovery…... [Continue...]

Black Magic Probe: The Best ARM JTAG Debugger?

We don’t always JTAG, but when we do, we use a Black Magic Probe. It’s a completely open ARM-chip debugging powerhouse. If you program the small ARM chips and you don’t have a BMP, you need a BMP. Right now, one of the main producers of these little gems is…... [Continue...]

Lighthouse Locates Drone; Achieves Autonomous Battery Swap

The HTC Vive’s Lighthouse localization system is one of the cleverest things we’ve seen in a while. It uses a synchronization flash followed by a swept beam to tell any device that can see the lights exactly where it is in space. Of course, the device has to understand the…... [Continue...]

3D Printed R/C Lifeboat

Radio control boats usually bring up thoughts of racing catamarans, or scale sailing yachts. This build takes things in a slightly different direction. A radio controlled lifeboat with a built-in First Person View (FPV) transmitter. [Peter Sripol] used to be one of the awesome folks over at Flite Test. Now…... [Continue...]

The Most Flexible Synthesizer is DIY, Raspberry Pi

[Ivan Franco] sent us this great synthesizer project that he’s working on. Or maybe it’s more like a synthesizer meta-project: a synthesizer construction set. You see, what Pryth has is a Raspberry Pi inside that’s running a custom distribution that includes SuperCollider to generate the sound, OSC for the communication…... [Continue...]
