PIR sensor assisted tracking...

I want to share my experiences yesterday while testing new fixes to PIR assisted tracking... I was having problems with the PIR assisted tracking because of some hardware issues related to PIR sensors (detailed writeup about the issue is on my other post at: http://myrobotlab.org/content/pir-sensor-retriggering-issues 


PIR sensor retriggering issues...

Using a PIR sensor in a robotic head project is awesome... while tracking with MRL, PIR sensor is helping to identify human presence and start tracking... I have tested this and proved to be very useful... but I have some issues now... PIR sensors have retriggering option for detecting human presence and movement and continue keeping the tracking process on... there is always 2 pots on the sensor, one for sensitivity adjustment (detection range) and one is for continuity of open circuit after triggering...


NIRcam images of a plant under IR light with opencv filters...

I prepared a new NIRcam for my Plantoid studies... after wrecking 2 webcam lenses I managed to properly remove the IR filter and calibrated the lens... while testing this new NIRcam I played with some opencv filters and finally captured these images which I wanted to share with you here... it is night here and the plant is illuminated only with an IR led array which i made for this purpose...

this is the opencv widget of the plant under IR light... no filters...

May 2014 update: Nowadays I perfected the printer settings and upgraded to latest Marlin firmware. I also began to use blue painter's tape which helps in sticking of the first layer better. I added a USB led light for night printing. While test printing I happened to own many miniature garden ornaments...

Update on March 2014:

Mechaphytum Animus is getting complicated... Now she has a fan to control temperature and a humidifier to control environmental humidity... I took this recent pic to show that she is alive... A camera and wifi is the next on the todo list...
