  Power and its power uptake
posted by zylesea on 28th February 2010


The eframe is working well with MorphOS 2.4 since a few months now. One of the main purposes of the project was to have a device that consumes very low electric power.
Over the last few years many things on other architectures have changed and improved a lot, too. But the eframe still is pretty competetive in the power uptake regard.
Usually it consumes a bit less than 30W, when the display is switched off the power uptake can go as low as 12W. With an exchange of the hdd with a flash memory the uptake should be able to get reduced once more.
Strong competitors are the Atom netbooks of course. They can beat the power uptake of the Efika on average usage, but the minimum value is still on par.
Not too bad, considering that the Eframe neither uses a mobile gfx chip nor a special power saving display.

Low electric power still is a power of Power!
  The Eframe does well on daily work
posted by zylesea on 23rd September 2009


In the meantime the Eframe has got a new housing and got several software updates. The system is running MorphOS V2.3 now and it works like a charm. I use the device on a daily basis as juke box, picture viewer, webterminal and mailer.
The new housing solved thermal issues of the first version, where the gfx processor and the inverter produced some serious heat that lead to some unstability of the system. But now everything works pretty nice and the system can run for hours and days without any problems.
This project is now rather finished (am working on some software though), and with the retreat of the announced 8610 and 5121 boards I guess the initial idea is no longer to pursue directly.
But the experince and evaluation I yielded with this project will help me with my future plans to develop multimedea display / POI systems.
  Kawooom - atom strike ;-)
posted by zylesea on 25th November 2008


Well, some years ago (IIRC 2005) I outlined a 5200B based device that was astonishing similar to the device class Asus introduced last year with the Eee netbook series (except processor and default OS).
Now Asus is going the AIO (All In One) route. Cheap iMac like devices. Stop: iMac like? No - It's rather like my Efika based Multimedia frame. Asus goal is to sell 5 Million AIO devices during the next two years as home multimedia devices and expects AIOs will take a 40% share in the overall desktop market within the next three years.Well, Seems I am right on track with my frame. And since I know the performance of Linux on the Atom (Eee 900A) and MorphOS on the 5200B (and on higher spec'ed devices) I am looking very forward to the availability of the 8610 based Efika. As multimedia media device that one together with MorphOS will have the power to blast any Atom based device away (aber sowas von!) .

Oops - Talking about Atom blasts: Generally I'd rather like to avoid any Atom blasts, but in case of that particular 'Atom' I don't care, but look quite forward. Kawooom!!!

  MorphOS 2.1 and a new housing
posted by zylesea on 2nd October 2008


MorphOS 2.0 on the Efika had some serious problems, but MorphOS 2.1 was delivered soon after. Now the system is running fine and relatively stable and does a good job.
Anyway, the case used now is not too stable and has a bad thermal concept. I just started to design a new case, this time more solid and with better features (the current one was a design study only). I'm yet undecided wheter I should integrate some new features (most likely an internal usb hub). The focus will obviously be on case quality and stability (to have it in a more robust condition to demo the system).
Hope to post soon about results of my latest efforts.
  MorphOS has arrived
posted by zylesea on 13th July 2008


Since a couple of days MorphOS 2.0 is officially out and my frame has gone to every day use. MorphOS on the Efika is really great - the system feels very snappy and the entire system quite polished. But now, used under stress and really frequent, I discovered some issues where the frame might be improved.
One of the biggest problems is the greater than expected heat dissipation of the gfx card. Using 3D (games, 3b blankers, but also Layers3D) does stress the radeon quite a bit and more heat gets generated than expected. Plus the gfx card is in direct neighborhood to the hard drive, which obviously does not like heat too much. I'll change the design quite is some regards.
But before I'll do that I am going to secure the non stopping picture supply for the frame and take many photos on Corse and Sardinia during my starting (on Monday) 3 weeks bike-tour.
  PowerDev meeting in Hörstel
posted by zylesea on 31st March 2008


I will go to Hörstel on beginning May to join the PowerDev meeting there. I am most anxious to see the 5121 board there, but also I am looking forward to meet some ppl there to get and provide some new input and/or just have some nice chatting.
  The wonders of low pass filters
posted by zylesea on 12th March 2008


I optimized some internal cabling, but was quite unsatisfied by the picture quality of the display then. But it's always amazing what a simple low pass filter can do. I am happy to have found a ferite and cable winding that filters away the disturbing high frequency noise.
  Plans for 2008
posted by zylesea on 11th January 2008


2008 has seen a couple of days already but I want to share my goals for 2008 with you.
To put it in a nutshell: I want to make a real product out of my desin study.
Currently I am working on material and methodical evaluations for a new frame. I did quite some research already, but still it will take me some time. During the next weeks I will build another design study (also based on the Efika1), the main design will keep the same, but it'll be better crafted and perhaps include some minor changes.
One of the next real big steps is founding a company. I will not do it "tomorrow" but soon. Fortunately with another product prototype (not computer related, but also electronic - even though *very* simple electronic (something with LEDs)) I do have a 2nd pillar for my company launch. But currently I am not able to spend as much time on these things as I would need to move it quickly forward, since I am in my last stage of my PhD (which I will hopefully have finished in summer).
  Energy uptake
posted by zylesea on 11th December 2007


At least I did some netto energy uptake measures.
The frame has currently an uptake of about 30Watt, w/o display this is 15Watt. I am not too happy with my ATX PSU it looses some power. The brutto energy uptake of the display is 15 Watt, but according to my previous measures the netto energy uptake of the display is 12 Watt, 3 Watt get burned at the PSU I'd assume.
Anyway, those 30W aren't too bad and I am looking very forward to the Efika2. My goal is to reach a netto uptake for an entire Efika2 based frame of <18 Watt (even better <15W).

  The frame in action
posted by zylesea on 12th October 2007


Well, I made some first pictures of the frame actually showing a bit more than the console output:



The quality of the photos is rather poor, because the light conditions were bad this morning wehn I took the pictures, but I guess they are sufficinet to get an idea about it.
Read more about it on my personal project webpage.
