My First Bot missing a cable for the Sharp IR sensor

I found what I think is a matching cable on DFrobots under Arduino sensor parts as a Cable for Arduino Analog Sensors. It looks like the right cable. It is 3 pins with a JST type connector. It is the best fit I can find since Solarbotics no longer ships the IR Sharp Cable with the unit. DFrobots sells the same IR sensor with the cable and that cable matches the Arduino Analog Sensor Cable and the Sharp part number as “JST -3 Sharp” for the cable.

Processing Andriod Hello World CtC

It is official, I have Processing (or at least the code that comes outta the Processing) running on my HTC Evo magic phone.

As always, much love to all who assisted in the nightmare that was the software install.

Woo Hoo!

 

This robotic hand can be controlled by a sensor-glove or a graphic program.

Explosion

First static test firing with hexaphenox propellant, using an empty C6 motor casing. Combustion chamber pressure was way too high which led to the explosion of the motor. Hexaphenox is a rocket fuel I have developed:)

Ok, finally, my new project :)

Yes, I'm starting a new project! This is what I've got:

A funny phonendoscope cover and a piece of PVC pipe. This robot will be the first of IBS (Isotope's Baby Series). I call it series as I hope there will be more robots which I build for my baby daughter. I will be posting my progress and more photos are coming. :D

Controlling motor speed with 293 without a POT

This is my first step to robotics. In this project all i did was use an arduino with L293D to control the motor speed without a potentiometer. this was actually an assignment / a small test given to me by CtC (chris the carpenter). the motor is suppose to speed up and down with a delay. 

"stop - ramp up - hold - ramp down - stop"

In my current project I have a rotary switch as a sort of menu selector. Read more

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
