Title: Tablet sounds..........
Post by: martin on May 27, 2013, 09:59:49 AM
I'm still fettling a small touring caravan, and rather like the idea of some decent sounds for when I'm away from home, to which end I've fitted a rather nice Alpine 95 watts a channel amplifier driving a couple of Wharfedale Diamond speakers - I'm getting a very reasonable sound out of it when fed from a netbook, except that if I run the computer powered by a switch mode power supply, there's some rather annoying background interference in the quiet bits (curable by unplugging the power supply and running off the interior batteries).........This has got me wondering - the netbook draws some 32 watts from the 12v supply, so the question is, would one of the new el cheapo tablets do the trick, use less power, and do the job? (keep seeing ads for sub-40 jobs these days running Android) - this sort of thing (which has been offered for considerably less from time to time) - http://www.ebuyer.com/494729-busbi-tablet-pc-111019 (http://www.ebuyer.com/494729-busbi-tablet-pc-111019)

Martin good morning to you,

A couple of thoughts  2 thoughts in one morning must be a record

1. I have a chum who was after a 'cheap' tablet he told me after much research that
http://www.amazon.co.uk/Pipo-S1-Capacitive-Accelerator-Compatible/dp/B00A8KZ1LU/ref=sr_1_2?ie=UTF8&qid=1365010360&sr=8-2
offers the best bangs for bucks, you could probably find cheaper if you shopped around.

2. If you just want to listen to music how about a cheap mp3 player you can buy really cheap on flea bay or amazon.  A simple interconnect from the mp3 headphone socket to the back of you amp perhaps the aux  or tuner input and away you go, my old phillips mp3 runs this way for a full days work between charges.  I love audio books whist I am pottering away.

at 32watts a tablet will run... forever from your 12v house batteries :-)

I would guess you could make much larger energy savings on the amp front than the sound source.

- funnily enough, I wondered about that so put an ammeter on the amp - at 1 amp it's surprisingly loud and fruity, at 2 or 3 it's party level! (Its only a 13 foot caravan) ralph:
I had though of the cheap MP3 player route, but thought that if I was spending money I could go for a tablet (ideally one that'd play from an exterior HDD).......

We had one of those cheapo Android 7" Tablets, about 100 a year ago, about 70ish now. The tablet was fantastic value and does most things quite well, but and quite a big BUT is the battery life is appalling when playing music, but what is worse is that when the thing is charging everything especially the touch screen becomes very unresponsive and erratic. We ended up getting a Google Nexus 7 for 159 which is just better all round, there is even a docking cradle now that has charging and audio ports, I think. The Nexus however does not have any Micro SD card slot for additional storage, although there is a 32Gb version at 199.

We have 32 GB version  nexus you can also put up to 20000 mp3 tracks on the cloud for free but you would have to be in  a WiFi hotspot to listen.  It just seemed to be worth the extra dosh would rather buy just the once, ereader at the same time.  Main reason for purchase.  Different level of expenditure than simple music player. Depends on what you want.
For general listening we use iPod interconnect to HiFi  but mp3 player gives more than satisfactory results, for very little cash.
