I don't like motor potentiometers, especially if there are cheap and small attenuators but big motors.
But big blue alps like ebay item No 350430125063 or
Alps Motorpotentiometer - hifituning24.de
only a bit better.

Here an overview of various additional examples

2) Audio Volume Relay Attenuator with IR Control
Audio Volume Relay Attenuator with IR Control
3) Remote volume control board, using relay - Halcro also use relay on their DA10 pre amp

For me a better option are semiconductor versions without mechanical devices for the attenuation like this:

Digital Potentiometers and Capacitors (ISL22317)

2-Channel 78 dB Audio Attenuator

Who knows URLs, where I can order Kits (similar to Velleman) where such IC's (ore discrete glue logic stuff) is in use?

Examples, that I have found, are this:
1) Remote Controlled Stepped Attenuator
Welborne Labs Remote Controlled Attenuator
2) RC-16 Remote Volume Control (looks like that one from Cyrus III and Cyrus IIIi / Cyrus 3i)
http://www.oxmoor.com/files/cut sheets/DCA-2 RC-16 cut sheet.pdf

But there are certainly much more offers.
Who can post more URL's ??

must be in category B, because there are no potentiometer is in use; the device looks like a pot is an encoder (double rotary switch)

I bought this one off eBay and it's junk: ALPS IR Remote Volume Control DIY Kit (100K)_Volume Control_Accessories Kit_Analog Metric Limited - DIY Audio Kit
The H-bridge is awful, it crowbars the rails until the MCU boots. The transistors are not saturated and the motor gets about 3.5V so it's ssslow.

What could be therefore the reason? Can you order and post the pdf schematic diagram ?? Then you certainly will get several advices from the members here to remove this not satisfy operating behaviour.

Hello
this thing could be interesting to control a motorized potentiometer as ALPS or Panasonic Infrared Remote Decoder Module Power/Volume/light Contr | eBay
But I have difficulties to see how to use it to control a motor, any idea ?

Exactly knowledge of the appropriate bus requirements (SPI Interfaces) are necessary. Where are the associated basic describtions to find? Thank you for calling some URLs and threads here on diyaudio in this case.

Hello

I think I found the easy solution. With this module L298N Dual Stepper Motor Driver Controller Board Module en vente sur eBay.fr (fin le 12-août-11 18:36:05 Paris) we can control motor rotary in both directions.

If I don't make mistake We have just to join :

D0 (PIN6) of IR controller to IN1 (PIN5) of Motor Controller
D1 (PIN5) of IR controller to IN2 (PIN7) of Motor Controller
ACT (PIN3) of IR controller to ENA (PIN6) of Motor Controller
Motor B+ PSU to VIN (PIN4)
5V PSU to +5V (PIN1) of IR controller and to +5V (PIN9) of Motor Controller
Ground to GND (PIN8) of IR controller and to GND (PIN8) of Motor Controller
Ground of 5V PSU and Ground of Motor B+ PSU

If we push on ">> Up" on remote control we have D0=5V, D1=0V and the polarity to have a rotation of the volume pot in direction to up volume

If we push on "<< Down" on remote control we have D0=0V, D1=5V and the polarity to have a rotation of the volume pot in direction to down volume


I have IR controller and Remote control, I will order Motor controller to finalise my project

Cordially

The alps pot requires 5V and about 200 mA to run. It is best driven from two small change-over relays because if driving transistors are not driven to saturation the volt-drop is large and the motor will turn very slowly.
It is simple and cheap to do if you already have a remote controller with two outputs UP and DOWN

Hello

I finished to test, with this two modules Infrared Remote Decoder Module Power/Volume/light Contr | eBay and L298N Dual Stepper Motor Driver Controller Board Module en vente sur eBay.fr (fin le 11-sept.-11 18:36:05 Paris) you just need a good 9V 1A transformer and a PSU with two LM7805 (one for motor and one for modules)

It work perfectly

Hi pascall, can you show any photo's or schematics of this setup please?
I'm looking for the 'simplest' motorised volume controller I can get and it's hard to find.!
Cheers

Pascal ? Where did you go ? I'm interested too. I don't mind walking over to the rack to turn on the amp; I don't mind walking over to switch the input. I don't need mute; I can just turn it down but I do want remote volume control.
If I have a clean amp and DAC source I do not want PGA2311 in the middle. I want to use LDR volume with 100K log pot but want to control the pot from my chair.

So for a more current BOM :

L298N Dual Stepper Motor Driver Controller Board Module 5V $6.69usd
L298N Dual Stepper Motor Driver Controller Board Module 5V For Robot Smart Car | eBay

Infrared Remote Decoder Module Power/Volume with remote handset $14.00usd
Infrared Remote Decoder Modul + Small 7-key Controller | eBay

ALPS Blue Velvet - STEREO Conductive Plastic Potentiometer, 100K, Motorized, audio/log taper volume control for LDR users $34.95
http://www.partsconnexion.com/product7383.html

5V regulated PSU , case, knob and interconnects

... am I missing anything ?
