DESCRIPTION
The internet of things has been upon us for years but hasn't lived up to its name. At Technical Machine (http://technical.io), we believe it's because the internet of things should be created by the people who know the internet best: web developers. Find out about the software and hardware that drives the Wifi-enabled, JavaScript powered, Node.js compatible microcontroller for web developers. When web development is freed from the confines of a screen it becomes even more powerful. It becomes about making new experiences. Pre-order a tessel at http://tessel.io/.

o
But hasn’t this idea been around
for 15 years?
electrical engineering tools really suck
SRSLY
Connecting to the internet is expensive
Hardware doesn’t have much open sourcery
But those problems are tiny
compared to this
behemoth:
The Internet of Things will be created by the people who know the
Internet best.
that’s youentrepreneurial. open. innovative.
lean. hungry.

Q: How do you teach web developers about
hardware?
A: You don’t. You teach hardware
about web developers.

Demo Time!(fingers crossed)
If the demo failed:
obligatory blinky light
plug & chug
node package name
event driven acceleration
use existing http libs

Web Development isn’t just about
making websites anymore.
Web Development is about making
new
experiences
