ESP8266 Development/SDK Board

Warning: do not connect the DHT11 temperature sensor as indicated in the eBay pictures, it is the wrong way around and will fry your board!

Update: Board has arrived, more details and pinout here

It would seem that the ESP8266 is quickly becoming a pretty well supported WiFI microcontroller within the DIY/hacker community, and certainly presents itself as a pretty good alternative to an Arduino for projects requiring simple IO and WiFi. There’s even a project looking at using compiling the Arduino IDE and compatible code for the ESP8266!

I have one of the original versions of these units, but ave struggled to get anything sensible out of it, and so was looking on Ebay for some more items and came across this breakout/development board. For £9.99 I thought I’d give it a go, and ordered it a couple of weeks ago. Will give more details when it arrives. More details and pics after the break

Arduino ECU By Brenamanf

I was sent a link to this website by the author, who appears to have created an Arduino ECU for spark control. Although the details are a little sparse, It appears that he has developed a lot of the required hardware himself. It looks like the main controller is an Arduino Nano and utilises Manifold Absolute Pressure (MAP) and a knock sensor to determine the ignition timing on a Peugeot 205 Tu9 45Ch. It would appear that the ECU has been developed over a number of revisions and has been in operation for over a year.
