An RF switch and remote would be okay but since the amplifier is just beyond the end of the bed I can always reach forward and turn it off myself.

You could try a oneclick power strip - http://www.oneclickpower.co.uk/home.htm - it has one 'master' outlet which controls power to all the others, depending on whether the 'master' is on or off. So turning off (on) the squeezebox would cut (allow) power to the amp. I have one (for other purposes) and it's great. The only issue would be whether the Squeezebox draws enough juice for the oneclick to differentiate between when it's on and in standby, if you see what I mean... if you can wait a week or two til I get my SB3, I'll try it for you ;) John Lewis sell them, I think £15-20 or something. -- oktup oktup's Profile: http://forums.slimdevices.com/member.php?userid=1117 View this thread: http://forums.slimdevices.com/showthread.php?t=17974 ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

The nearest I got was a solid state device that could switch 230v/3A. The specific part I was looking at was for US mains power (120V/8A) - Sharp S102S01 - see http://rocky.digikey.com/WebLib/Sharp/Web%20Data/s102s01.pdf The S202S01 should work just fine for 230V EU mains. At this point, though, we've determined that the speakers / amplifiers in question (the ones that would be switched) consume about 140ma continuously - whether producing sound or not. That level of consumption converts to about $6.25 (~5.20 euros) per YEAR in excess power cost. So - any solution has to be REALLY low cost to pay off in any reasonable time... Felix's idea, while pragmatic, just grates against my elegance-meter... It would certainly not be useful for a commercial solution.

They may not necessarily mind having folks open things up to check seating, perhaps swap a display. But modify the circuitry? Hard to imagine continuing hardware support in that situation ... What I'd really like is some sort of dry contact type closure. If the unit is on, allow me to sense that via continuity across two pins. If the unit is off, continuity is lost.

This follows up on abdomen's suggestion that a basic IR controlled mains switch would be the simplest way of doing this - at least for those of us who are not gifted with either the time or the skills to go cooperised's route (and sadly I have neither). After a little searching I found a velleman project kit (some simple assembly required!) which offers an IR controlled 240V 5A relay. It is the K6713 available from CPC in the UK for £20 here http://cpc.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=HK00755N=411 (you may have to click on this link twice to get the right page) and info here http://www.velleman.be/common/product.Aspx?lan=1id=9356 . The next problem would be how to get the right IR code output from the IR blaster. There is a pronto ccf for the velleman IR codes from remotecentral.com, but I don't know how you could put these codes into the plugin.

Hi Andy Unfortunately not. The IR code in the firmware is implemented as a ring buffer of 50 32bit values. Each consisting of 16bit for high- and 16bit for lowtime. There is a 'process' checking this ringbuffer and sending out the IR bits (32bit values) accordingly. Each IR bit is sent in one of three modes: high-low w/ carrier, low-high w/ carrier or high-low w/o carrier. The modes are triggered like this: high-low w/o carrier (ITT): hightime = 1, lowtime = variable low-high w/ carrier (RC5): hightime = variable, lowtime = 0 high-low w/ carrier (NEC): hightime != 1, lowtime != 0 So for ITT mode the hightime always needs to be set to one. The firmware then set the IR Blaster output to high for about 20uS followed by the lowtime where the output is set low.

[slim] Re: Options for remote power on of non ir amp
Hi, I'm the friend of Max's who'll be building the PSU for his new amp. I thought I'd post my thoughts so far, having read through the options. Ideally, of course, the amp power should cycle with the squeezebox power, instantly and transparently - just as if the squeezebox contained a power amp of its own. Solutions involving another remote, or even an unused button on the SB remote, just don't satisfy my sense of neatness I'm afraid. ;-) The X10 route, though neat, is expensive; it's also overkill for such a simple application IMHO. In the absence of a geekport, I think I'll end up going down the IR blaster route, with different codes for switch on and switch off - I don't mind doing a bit of decoding, for example on a cheap PIC (the 6-pin 10F200 is 55 pence here in the UK). Can anyone tell me more about the IR blaster? How easy is it to send custom codes at custom baudrates? And how much of its functionality is in firmware? For example, it would be useful to disable the 38KHz carrier, since I'll probably just hardwire the IR blaster output into the PSU. Is this possible? For anyone who's interested, I'll be using an optoisolator and a triac to switch the mains supply to the PSU (it's a cheap, small and silent solution). The same trick would work for any mains-powered device, so I'll try to make the schematics available once it's built. Thanks in advance for your help.

For example, it would be useful to disable the 38KHz carrier, since I'll probably just hardwire the IR blaster output into the PSU. Is this possible? IR Blaster works like this: For each bit in an IR command the plugin sends a high/low time value (in microseconds/modulation) which tell the firmware to send for hightime and wait for lowtime. The firmware also applies the carrier during the hightime. But there is a mode for remotes that do not use a carrier. The format is called ITT and consists of 20uS hightime and multiple of 20uS lowtime.

Hi all Here is an idea to (mis-)use IR blaster output to trigger a relay. One could code a plugin sending out an IR signal constantly while SB2/3 is turned on. A little logic (timer) hooked up to the IR blaster output detects the signal and turns the relay on for a couple of seconds. If more IR signals arrive within time the relay stays on. As soon as the SB2/3 is turned off no more IR signals are sent and thus the relay turns off some seconds later.

Hi Max This should be possible with a 'special' IR file that only consists of one 'on' and 'one' off time (i.e. one bit). However the signal is always modulated with about 38kHz which means on the output you get a couple of pulses. The other problem you get with this approach is that SB and amp can get out of sync since you don't know if it's a 'power on' or a 'power off' IR signal unless you also decode the signal.
