Interactive Voice Control


Interactive Voice Control
Basic Functions: Power Supply

I've started work on Rob Meyer's Interactive Voice Control board... I've got the Power Supply section running, which replaces the four D-Cell batteries, the four AA-Cell batteries and the power switch on the Hasbro Droid.

The IVC board's power supply section is designed as to replicate the original battery system, allowing the new system to operate on 12V Astromech power.

Here I'm running a 12V, 6A Benchtop Power Supply, which powers Dan Stuettgen's Power Distribution Board.  That in turn supplies 12V to Rob's Interactive Voice Control board, which distributes the various voltages to the Hasbro system.

Battery Boxes


Just received my set of PVC Battery Boxes from Matt McCormick.

Nice work, Matt!

These are sturdy, clean, almost ready to paint Battery Boxes constructed of PVC pipe and expanded cell PVC board (aka Sintra). They are built to club specs with one small exception: the overall width of the boxes is about 2.87” (instead of 3”).

R2 in progress, part 7

R2 as of 11.08.2011.

Note the new PVC Battery Boxes.  Niiice.

Dome Drive Assembly



This week I "upgraded" my Dome Drive Assembly - I installed the Engraved Dome Drive Wheel from C5 Orlando 2010, offered by Guy Averett.

As far as the Dome drive Assembly, I took a slightly different approach:

I inverted the Drive Brackets so I could use the longer shaft version Pittman motor.  With the short shaft version, I wasn't able to mount the drive wheel low enough to install the Dome Plate.  With this setup, there's no need to cut down the longer shaft Pittman Motor, and the drive wheel now sits low enough to allow the Dome Riser Plate to be installed.

Drive mounting brackets are custom CNC machined, based on JAG's Dome Drive Assembly drawings.

Center Foot Fixed!


New Custom Built, CNC Machined Center Foot.  Per the "Official Blueprints", the Center Ankle pivot hole is located 0.625" below, perpendicular to, the top of the foot.  This allows for 18° of tilt.

New Primary Sound System

Arduino Uno + Wave Shield

Arduino Uno (Atmega328)
Adafruit Wave Shield
Kingston 2GB MicroSD card w/ SD/MMC Adapter

QKits  FA604: 8 watt mono Audio Amp (not shown)
One (1) Pioneer TS-A878 3.5" 2-Way Speaker (not shown)

Fully programmable, using the Arduiono Uno, the Wave Shield plays up to 22KHz, 16-bit, mono (yes... mono) PCM (.wav) files.  It's a low cost, small package, has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an SD/MMC card.  Volume can be controlled with the optional on board thumb-wheel potentiometer.

The amplifier is a mono IC amplifier, using a TDA2030 IC with 8 Watts output.  This amp runs off of 12VDC, has a 94 dBA signal/noise ratio and a 20Hz to 20kHz frequency response, all in a small, low cost package.

This is my Droid's Primary Sound System with the Secondary System being the audio portion of the Hasbro Interactive R2 conversion.
