1  Hardware and U-Boot firmware / Hardware / Re: How to power SheevaPlug with AA batteries? on: October 11, 2010, 03:05:29 PM
We've got the solution on paper to use a 7.2v 26000 lithium ion cell (off the shelf product) with charger that will run a unit for around 12 - 15 hours.

We've also developed a 10 inch touchscreen version of the plug(tethered currently) which is available to order and can have either a guru standard or a sheeva inside. It's not a light weight tablet tho... more a rugged slab - hence the products name 'the slab'.

no we cant solder it on.

Our problem is not trying to get it cheaper.. we need the main board to have a lower profile and the addition of a sata port and second ethernet is not an option as it adds around 15mm onto our new designed product.

The flash memory is too slow and only has a number of data rewrites until it degrades so no the facility on the board is not suitable.

Having a version and then a 'plus' version you'd expect the base version to have a similar spec , and the sata connection makes the onboard memory a bit of a waste of money as most would boot from hdd. further the fact that the plus version has 2 memory sockets you'd have expected at least 1 on the 'standard' version.

the cost factor between guru and sheeva is the jtag. for less than a few usd the standard could be a whole lot better. and to be honest i'd pay the extra..

so far from discussion with resellers everyone is buying the plus 5 units to every 1 standard therefore making the standard a waste of development expenditure..

We've abandoned the plugs psu for a 5v 2amp cisco plug psu and rewired the power cable to a dc jack socket

Not being funny but as they are skrimping on component features on the guru instead of spending a few dollars more you know that the psu is awarded to the cheapest manufacturer, and having examined the craftsman ship and bakeolite board - the decision to dump the psu for a nice cisco off the shelf POE 5v PSU was a no brainer.

The cisco psu costs around 8 USD or 5.

It appears that Globalscale are not putting on a 20 cent part on to the board to allow memory expansion on to the standard version of the guru plug. - NO SD card wsocket as it's 'optional'.

As a company thats invested thousands or dollars/ gbp into product development to create a range new devices my level of frustration and anger with this penny pinching attitude is off the scale currently. Why they would develop a new standard product and not feature the same as the sheeva plug is beyond me.

Our designs are suffering from globalscales stacked USB plug instead of 2 x mini  usb( a more sencible option i'd suggest, and only offering the memory socket on the SATA version adds over 10mm on to what should be a 30mm deep product.

Whilst we all understand unit order quantities for bespoke development - but not putiing a surface mount memory socket on a board thats already got it on the PCB is ridiculous.

This is not going to be a TV but will playback small 600 x 480 video and testing thus far is fine at that size. Most who have contacted me since the initial post are looking for a graphical display not a full screen media streaming device, and thats essentially hat we're doing with it. So nope we aint playing DOOM3d on the unit.

We're not using Mimo as it's not rugged enough. GlassFilm Glass touch is pretty awful on the Mimo.

Yes it has touch and we have sourced and could fit a webcam if we wanted. We're also finalising the 10 inch and possibly 19 inch version and personal projector version.

The Plug needs more ports tho... as we dont want to throttle the USB. Maybe this might get Globalscale to give us more?

Okay, now dont all shoot me now.... but heres what we've managed to drum up from our tiny brain cells... If any of you want a neat little unit like this get in touch as we will be selling some in the next month..

Knowing the costs involved with all this stuff the $200 will be a lot of BS down to the fact manufacture of such a device will be about that kind of figure. If it's touch it'll not be as tough as demand dictates either.
We've been looking at the toshiba tablet due out q1 this year and the bottom line is the battery fails the market demand.
Marvell could be more accepting to us asking for items like more usb ports, on off buttons and built in wifi. Perhaps if we had this a lot more would be developed sooner.

Nice new pic of the plug on the design ideas competition however the new image shows a very different config on the board layout... Please dont say thisis a mod that's about to be launched(we've designed our stuuf around the old board.

 2Ghz power - the processor is 1.2 is this a new processor upgrade....Why cant we have more ports than power??

POE is possible as it can draw up to 2.something amps...

If you need a POE adaptor I recommend the Cisco 5v POE unit...

You also need to look at the other USB devices being loaded into the unit. Using NIMH is more economical and will give longer life than other cell types but you need to take care if you are planning on recharge plus power. Nimh battery protection is harder to source than Lithium Poly cells etc.

Hi all,

Dev on the plugs going well btu we've hit a question... anyone know how to add an on off switch on to the plug that will safe shutdown or 5 second press kill the unit?
We have got a reset but we really need a power switch option or some ideas on how to do it?

Call me dippy but the instructions state to extract the tar and then put the USB into the plug.... As there are issues with windows and the linux file(dostounix) format I changed it to expland the tar using the plug..

i'm still getting

/runme.sh: line 19: ../scripts-linux/openocd/openocd: cannot execute binary file

Can someone explain this process a little clearer.

Guys many thanks for all the support so far, we're opting for the 740 and have had the many ideas. To that effect and to share a little we're doing 2 or 3 case designs for the product that we can offer for OEM use. They will all be metal cases profiled for the 740 and the sheeva plug, we are also considering a 15" Touchscreen as well. If this is of interest PM me or get intouch via our website. 740 Case Prototypes are around 3 - 4 weeks away.

Have you had success with the webcam or the touch yet?
