fr3shb0t was created as the final project for the physical computing class. It uses SpeakJet, TTS256 and PIC16F88 microprocessors and an ultrasonic rangefinder. If someone comes close to fr3shb0t, he gets excited and hits on them! He says “Hey, good looking!”

The first step of my talking robot project – test whether this Speakjet chip works! Strangely, I couldn’t find much help on rigging up the demo/ test mode for the chip so here it is. I used a AA battery pack to power the breadboard and an LM386N op amp to hookup an 8? speaker to get sound out of the chip. The chip circuit is the demo circuit on the Speakjet datasheet and op amp circuit is the gain=20 circuit from the op amp datasheet.

This cute little blue bunny goes insane and flails his arms when it’s tummy is warm. It has 2 servo motors for the arms and a thermoresistor to sense the heat. Clay and me made this for a physical computing assignment.

In this circuit the PIC chip controls a second chip SN74HC164N for a SIPO shift register to control the LED’s. I built the circuit and the code was provided to us by our instructor (Joel Murphy).

Code lock Code lock 2 Code lock 3 Blinking LED's Blinking LED's 2

The first 3 pictures are a code lock using LED’s built in class. When the right code is entered using the buttons the green LED lights up and you can reprogram the code. If the wrong code is entered the red LED lights up. I built the circuit and it uses the program written by our instructor Joel Murphy. The last 2 pictures are of a blinking LED which I built and programmed for homework. Here’s a video of the blinking LED sequence.
