Cheapest Remote controlled input selector.

Hi Guys.
Need Cheapest Remote controlled multi input selector. Kindly guide.

You want volume control as well?

Not the cheapest but the Arduino LDR Source selector is pretty user friendly.

Otherwise- cobble together something from ePay- a relay source selector and alps motorized pot from China.

Yes volume control as well.

Did you do the search? Do you have some candidates already?
It can give us a hint at what you are aiming at.

I have seen some $30 Chinese 2.1 channel speakers with remote and multi input selection. and these are working quite well . I want to understand -What hardware are they using to remote control inputs and volume.

If you're looking for something already built, there is a kit quite common on eBay. Look for something with "lite" in the name. About 40$ but the source selection doesn't work too smoothly.

If you want to roll your own, have a look at my thread in this forum. A preamp for the average guy or something like that. I might offer the PCB files at one point but not before testing... Probably not before October or so.

 

[viki_v2]

Can you explain as what parts go in making.

 

[00940]

Well, you need a IR receiver, a micro controller (or something like an Arduino) to decode the signal and turn them into instructions, relays to switch the signal, a motorized pot to control volume and some electronics to interface the controller with these. And obviously a remote. And a power supply.

6 input and you get a 100k log Alps pot in the deal.

Yep, that's the one I had in mind.

That one is quite expensive. How are these generic 28$ 2.1 speakers having a remote and display. Any idea what hardware is used in them.

 

[georgehifi]

Here's cheaper but so is the pot. Gota remember an Alps pot is $20 by itself.

Just looked at such speakers on ebay -> HIPOINT AUDIO 2.1 SURROUND SOUND SPEAKER SYSTEM WITH BLUETOOTH USB & REMOTE | eBay. It looks like the remote is only for controlling the playback via Bluetooth: play/pause, next/previous track and that is it. It does not let you controlling the volume or bass level. Those are standard potentiometers with knobs on the front panel. There is also no input selector as far as I can see. If you have other set of speakers in mind then post the link to it so we can see what you mean.

It looks like all controls are done electronically in that unit. No relays, no mechanical potentiometers etc.

 

[00940]

Well that would be the cheapest option. A analog multiplexer, a cheap digital volume control. They can interface directly with the uC.

 

[viki_v2]

I have not yet understood what parts cost so much.

 

[00940]

Motorized pots are not cheap. Not are relays. And they need a fair amount of current so it adds up to the total cost. Replace the pot with a digital one and the relays by a multiplexer and the cost can be reduced significantly

 

[havefun]

The multiplexer has poor channel separation.

 

[00940]

It depends on the multiplexer ic but yes, some are pretty bad. There's a reason it is a low cost solution ;-)
