Infrared Remote Contr. Stepped Attenuator for Replacing RC Motor Volume Contr.Alps
 
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

A: RC Motor Analog-Potis

5) TentLabs Volume control

B. Remote Controlled Switched Resistors by Relay
1) The remote control paratactic volume control

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 Potentiometer
Digital Potentiometers and Capacitors (ISL22317)
Digital Volume Control
Volume Control - Volume Controls (CS3318)
2-Channel 78 dB Audio Attenuator
LM1972 - Micro-Pot 2-Channel 78 dB Audio Attenuator with Mute

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%20sh...ut%20sheet.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)

No news?

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 ?

Pascal

Just connect 3 to 8 line decoder. The output will appear on one of the pins. Connect a reversible motor driver IC. For reverse direction, some other pin will go high.

Enjoy

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.

I'm building a relay-based log attenuator with IR remote, as everything is multi-channel now.

tiefbassuebertr,

There is bentaudio.com that you can look at.

Very interesting, also the other devices - thank you therefore.

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.

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-aoŻt-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

Nico Ras 8th August 2011 06:08 PM

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
