LadyBot is my robotic head which I am working for long. She has 3 microprocessors and 5 servos for the animatronic movements. One Arduino is dedicated to webcam and MyRobotlab to track faces. One for the head movements. Now I added voice recogrition and interaction via bluetooth. She responds with some predetermined sentences on a MP3 player, command and interaction using android bluetooth app which converts text to speech and vice versa.

My project about controlling the speed of a motor by your mind... This is an Arduino and Neurosky ThinkGear module project... Mosfet motor driver circuit is as follows:

My plantoid Mechaphytum Animus is interacting with web thanks to ESP8266 webserver nodes... I played a lot with this tiny wifi modules and managed to incorporate them into my projects in many ways.... Easy to connect to a MCU, open source firmware and lots of example software on the web... I prepared many webservers with or even without a MCU and now Mechaphytum Animus can send sensor data to web, can Tweet and even send e-mails to me when an event is triggered... Below are my ESP8266 webservers...

I recently ordered a Lidar Lite from Sparkfun... This is a very capable distance measurement device, a laser rangefinder  in a very compact form and is also relatively cost effective... Pulsed Light company  first carried out a successful Kickstarter last year and now the device is commercially available... Link to manufacturer:  http://pulsedlight3d.com/ 

After struggling with Neurosky Mindwave headset a lot I decided to make my own sensor to use in some bio sensor projects... I found that there is a cheap and easy to use instrumentation amplifier signal interpreter IC, AD620AN... 

Update on July 2014:

At last I found some time to finish up and test my filastruder... Tested with recycled plastic pellets at PID values: 200 degrees C +-10 degrees... Managed to extrude 1,70mm usable filament at first test run...
