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?

buy a huzzah from adafruit, it breaks everything out, and is much more tolerant than the board itself.

couple it with a small breadboard and an mb102, and you're good to go.

We've been running a series of experiments to try to mitigate the randomness of what achieves liftoff from /newest. We started working on this because many users complained that good stories were getting ignored, and we looked closely and found that this was true. Below are links to a few comments I've posted about this over the last year, if anyone's interested. The next experiment will probably be to add a profile…

Cool! Thanks for working on making interesting stories more visible.

What would be awesome is if by doing this the community system gradually trains itself to post more interesting stories in the first place.

aliexpress.com

Got a link? There are a bunch of them there... But i'm kinda curiouis which one you bought. So i don't have to analyse things all over ;)

no link, the place i bought mine from in august doesn't appear to have any anymore.

i recommend buying the esp-12e, and the first one on my search comes up at $1.97. note, these things aren't breadboard friendly out of the box. if you want that, buy a huzzah from adafruit or buy one of the breakout boards on aliexpress (17 cents each or so).

a temperature sensor was actually my first use of it (and i will continue to build a couple as remote sensors) - basically, i've been adding more and more sensors just to see how much it could take. now, i'm having to build out PCB's to support everything (including the voltage regulators to 3.3v and 5v), as i've outgrown breadboards.

Thanks, that is my plan too, add as many sensor as I could! For the moment I have a microphone, a water level and a couple of temperature sensors waiting for a microcontroller. Could you link a couple of links to resources you found useful? I haven't look at it properly but when I try to search I was a bit confused and not sure on where to start

https://github.com/cesanta/smart.js/tree/master

using the arduino environment, i had a circuit up reporting temperature in less than 5 minutes.

For the 12E to start with, take a look at the nodemcu dev boards. More expensive but it's a great little board to start a project on and then go to the bare module since it includes all the usbttl, and regulator stuff.

thanks! I didn't know about Cesanta so I made my own from scratch, but it is very bulky.

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…

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