First step towards motor control

Constructed the L298 motor driver from Solarbotics.

NOw time to start constructing the motor systems to make a kinetic scultpture.....

Stepper Motor control

Using an EasyDriver to control a stepper motor.
Good tutorial http://danthompsonsblog.blogspot.com/2008/09/easydriver-v31-tutorial.html

Stepper Motor liberated from CD Drive and Floppy Drive

Belt driven robotics

null

Positioning objects in an XY plance require belts and stepper motors

There is an interesting set of brackets, pulleys, worm gears at http://www.vexrobotics.com/vex-robotics-advanced-gear-kit.shtml

Construction

A great set of links on http://www.arrickrobotics.com/mechpart.html

Belts and sprockets http://www.hobbyengineering.com/H2028.html



from Tamiya......

 

 

They also have pulley sets

Motor control

Control of a basic motor using Parallax Motor MInd B http://www.parallax.com/

or the Secret Drive kit from Solarbotics that fits INSIDE a servo http://www.solarbotics.com/products/k_smd/

or the bigger version Kit #13 - L298 Compact Motor Driver Kit from Solarbotics 
http://www.solarbotics.com/products/k_cmd/ which usable from 6 to 50V, at up to 4A total output current

For stepper motors parallax has the Little Step-U Motor Controller at $70 it can save a lot of time and BS2 computing time

Breadboard Power Supply 5V/3.3V

A very simple breadboard power supply kit that takes power from a DC wall wart and outputs a selectable 5V or 3.3V regulated voltage. The .1" headers are mounted on the bottom of the PCB for simple insertion into a breadboard. Pins labeled VCC and GND plug directly into the power lines. The lone pair of pins have no electrical connection but help support the PCB.

Atari Joystick as controller for ROV

To control the motors on an ROV, maybe use an old Atari joystick, and here are the schematics.

Electronic lock uses a mobile phone

E-Lock is a touch tone activated electronic combination lock which is controlled by the keypad of a mobile phone. When the correct combination is entered, a relay on the E-Lock circuit board is activated. The relay can be connected to a solenoid (not included) controlling the lock on a door or cupboard. To operate the E-Lock, just hold your mobile phone close to the built in microphone and then enter the lock combination on the phone keypad all at apogge kits

conductive thread, ink, fabrics

I could paint with silver impregnated paint ot create circuits, or make paints as shown in this instructables, and there are even pens, and conductive thread out there........ endless possibilities as shown by the great work of Leah Buechley who also has a great links page.

microfiche reader

microfiche reader that then plays music depending on light levels.  Uses a light sensor and a BS2 to output midi.  Shown at this years Maker Faire.

arduino water instrument

great arduino based MIDI work including Toriton water surface instrument by Sebastian Tomczak

arduino glockenspiel

Intersting glockenspiel driven by an Arduino.  USes solenoids and are powered by arduino

small servos, gears and joysticks

pan and tilt system for cameras or servos and small joystcks and also have gears and mechanics for servos

bs2 program for ping)))

Using the PING))) ultrasonic sensor I can change LEDs flashing colors with changing distance of a person.

distance ranging and detection

Current project needs a method of detecting the presence of someone in a room who is approaching an interactive sculpture.

First I need to detect that someone is in the room (which activates a response from the sculpture).

Then I need to measure the distance of the observer from the sculpture, as the closer someone gets the different responses will be realized.
This distance detection could be either from an ultrasonic sensor
(from Parallax), or the low cost infra-red detectors from Sharp which are available at http://www.acroname.com/robotics/parts/R48-IR12.html

multiple servo control from PC

Mini SSC from http://www.seetron.com/ssc.htm are useful when using multiple servos (up to 8), controlled from a BASIC Stamp or a PC.  Thanks to the Physical Computing book which is fabulous
