Test rig :- 4 IRs dangling from space

Its basically a Nintendo WiiMote camera which is able to track 4 infra red leds/laser giving XY coordinates and also the size of the blob seen.

I have been experimenting with OLED displays, json strings and Web Weather sites.

I plumped for the wunderground.com weather site.

You have to signup for a free account which allows you to poll the site 500 times a day (hum...so a scan every 2.5 minutes...not bad). They then supply you with a YOUR_KEY (see below).

I am using an ESP8266 as the wifi link to wunderground site.

ESP8266 gets some visual feedback.... 128x64 Oled display.

ESP8266 meets the force....
Using the code posted here https://gist.github.com/tagliati/1804108
for the Arduino, with some minor changes it ports easily over to the ESP8266 WIFI ........

What is "Blynk" .... It is a Smart Phone APP that uses either Android or iOS to IoT your projects for remote control.

Where can I buy some Japanese elves  ?.....

Continuing the theme with my ESP8266 WiFi "Wonder" chips.

First experiment in making a sonar scanner for remotely displaying depth/distance mapping.

The MaxSonar EZ0 is mounted via a 3D printed mount directly to a simple stepper motor.

The Stepper motor is controlled directly from the ESP8266 output pins.

Finding the SVG details opens up a whole new jar of grubs, means that the tiny ESP8266 can grow its own display unit.
