For someone wanting to tinker but not being great at electronics project, what is the easiest way to: - Play with the chip (testing interfaces, deploying code etc) - "Deploy" it (ie. connect it to ground power, via 230v-USB connector or similar?

Onthe software side, the Arduino programming environment now supports the ESP8266. This makes it very easy to start playing.

One hint - to program, reboot with the programming pin (GPIO0) grounded, but take it back to 3.3V before you start programming. That took me a couple of hours to figure out.

this is indeed probably the best low-cost wifi chip out there, most of the esp8266 modules are still acting as an add-on module for other host-cpus(e.g. arduino) though, wish it can run something like freertos or contik on its own so it can be a IoT sensor standalone(maybe it's there already, had not checked it in the last few months). TI had similar products but it's too expensive, in that sense IoT hardware has to…

And ESP8266 is now supported by the Arduino IDE. See https://github.com/esp8266/Arduino

Whoa nelly! This web site is running entirely on an 8266, responds instantly, and is handling the kiss of death associated with HN linking with no problem. That is amazing.

this kind of thing gives me hope that Google could be replicated on a low budget

I was told the core team of esp8266 are all ex-broadcom wifi designers.

Doesn't look like it [1]. Certainly a skilled team though!

I guess, when they come out with microengineers.

There is a firmware to run lua directly on the esp8266: https://github.com/nodemcu/nodemcu-firmware

I have been messing with nodemcu on an ESP8266 ebay board for the last few weeks. It was initially really weird to have a REPL on an embedded system but I'm already missing it when I go back to other platforms.

i am continuously impressed by the esp8266. i have been building things on and off with them for the last couple of months, and bought enough of them to give out. at less than $2 each, they really are amazing.

I bought one as well although I didn't do anything yet, would you mind share what you did/recommend doing? I was thinking to make a temperature sensor monitoring device, as I have an arduino that is doing the job now

I've made motion sensors (still slightly buggy) and a small circuit to start my laundry machine remotely. I might do temp/humidity monitoring for a specialized application at some point.

I was thinking mainly of infrastructure...

This reboot is forced, we had over 3k requests with no hanging of whatsoever. It just helps when traffic is huge. This particular chip (serving linked website) is running at 80Mhz.
