I have attached slides from Jason Kridner's Physical Computing with JavaScript presentation at Sketching in Hardware 2013 (http://sketching-in-hardware.com/).

Great slides! Initially in the past I had been confused, because since Javascript runs on the browser, (and I hadn't heard of Node.js) I was a little confused and had thought that I'd need a browser opened…

Jason told me he hopes in to add UART, SPI and I2C over the next few release so that Bonescript will be fully featured. Interesting post recently from the TinyG guys: https://plus.google.com/102479037893713042691…

Extremely low barrier to entry and only one composite type, so an hour after flipping through its description you can be fully productive by jumping off from past programming experience. Lua really and truly is a "KISS" language, and that helps its embeddability by keeping things small and simple. I guess that's why so many engineers like it. It's designed for this niche.

"The new BASIC" is a really good metaphor for Lua.

PS. Naturally available in ARM Debian, but also in Angstrom which highlights how pervasive it is. (Lua 5.2 is in Debian, but only up to 5.1 in Angstrom --- that's fine though. Lua is long-term stable, there is no upgrade treadmill.)

I've heard lots of good things about LUA over the past few years, how fast, compact and convenient it is. I'm looking forward to trying it sometime!

Lua and server-side Javascript are the new BASIC.

As a result of 3D printing, blue tape may be taking over from duck/gaffer tape in the geek Tape-All-The-Things meme!

Very nice. Thanks! There was a simple example of the node.js program serving a web page and socket.io comms to it in a subfolder here, so that's a good starting point to developing a UI portion for applications.
The screenshot below was from their flickr page, the code is not checked-in I guess currently (I couldn't see it at that github) but the screenshot provides some ideas. Very neat that all their control to the hardware was via bonescript, so no need for any C/C++ code in their particular case.
