looks promising. :D

hehe art or robotic ?

i rate 5 star because it is very original and aesthetic !

just cooooooooooooooolllllllllllllllllllllllllllllllllll
dude, you gotta show how you made that proximity sensor. i wanna know! :D

it seems a straight  ir diode vs ir photodiode under vcc

is ti?

Hello, It is a little of art an a little of robotics, the proximity sensor works very well, detects white objects 40 cm far (aprox. 16 inches) or less distance, detects in light and darkness, it isn´t straight, the diode works in a frecuency, and the receptor filter the pulses of this frecuency, amplifies it and drives a transistor connected to an input of the PIC. I recently finish the last version, the pic and video are old, the design was changed a little to be more resistant and easy to build.
the modulated ir receiver is a standard 38k all in one receiver or did u develop a your own band pass filter + rectifier in order to detect the carrier?

It´s a circuit I design, I used an LM386 audio amplifier with the receiver in the place of the mic and a transistor in the output, but change the input resistance with one that works better (doing test to find the better value), I don´t know in wich frecuency the circuit works, the pic drives the IR emitter and the frecuency depends on the loop in the program. I did´t measure or calculated it.


Nice build.

Is this a commercial product? Where can It be purchased?
