Efika.org is online !

It's a new website dedicated to the EFIKA book and all related information and translations.

It will be the Powercollaboration.org companion for this project.

Hehe, nice! :)

Geit

Seems an interesting idea the one about the book.

I've setup a page at the gentoo-wiki:

http://gentoo-wiki.com/Efika

Some of the info is gentoo specific but most applies anywhere. Maybe you can find something there of use.

very interesting, just found this PSU link off there

anyone know of a UK supplier of these perhaps?.

Uk supplier: http://www.mini-itx.com/store/?c=10#p1835

Hi.

Considering that they are quite expensive per piece, but get cheaper in quantity, maybe we should find out how many people need them and then we can buy them in quantity?


Best regards,
Johan

Yep, I have a blog... PurpleAlienPlanet

Matt has been working on this and we are considering an offer in the PegasosPPC Store.

R&B :)

thanks nixnut.

as usual, the UK retail ripping off the consumer 8(
£52.88 inc. VAT, but at least its available and in stock so thats a plus.
(currently 1 USD = 0.507374 GBP 1 GBP = 1.97093 USD)

in store, BBRV, as in, order the full package (if we find, or have some cheap injection molded basic [cube]case or converters made as well sometime +)EFIKA+PSU for an all-inclusive price and shipping type thing ?.

did he find any near (perhaps a small hack or drilled hole etc)EFIKA to standard frame converters/adaptors ?.

For those who want one in France :

65€ ... I guess I've no choice but buying one ...

Thanks for all those very interesting links :-)

yes, thats the cheaper £39.95 inc. VAT one
Plugs directly into the motherboard ATX connector. This new 80W version generates up to 80 Watts of power from a 12V supply, at over 96% efficiency. Apart from the maximum power output, all other specifications are the same as the original 120 Watt version.
I.e
An attached cable harness provides two HDD and one floppy/slimline optical drive power connector. Cable lengths: from board to 12V DC connector is approx 25cm (9.75"); cable harness is approx 40cm (15.75") long.


it seems to have the advantage that its able to power
3.5 drives and floppy but needs 12v as input were the other can take anything from 6 to 26V.

but as 12V is car battery standard all round the world perhaps thats a better option and you can get cheap solar panels at that 12v rate very easy.

iv not looked into it properly yet but you would need larger (or more smaller)panels at the 12v rate to supply the required hourly rates to your battery pack for 24/7 use.

if your just going to use standard car battery power then its not a problem.

for the adventurous/Experimentation, theres also the PEM fuel cell
"
The fuel cell uses a Proton Exchange Membrane or PEM fuel cell. PEM Fuel Cells utilize the energy from the electrons given up by hydrogen ions (or protons) during the reformation of water across the membrane to run the car’s motor. The fuel cell is "reversible" meaning that it can both split water into hydrogen and oxygen, and combine hydrogen and oxygen into water."

Double - cell PEM electrolyzer stack, for production of hydrogen from distilled water.

they do prototype industial units too so it could grow into a commercial self contained unit if your looking to grow the markets for better power cycles per hour for powering the likes of low power EFIKA, wireless MESH networks etc.

ill leave it upto someone else to find and post a super small wind turbine/battery pack just big enough to power an efika and/or a mesh wireless router.....

(sorry i cant seem to revert back the width since i put that large picture in , and i forgot the syntax for enclosing long urls, this will do perhaps?)

Popper:
Fix your link with proper BBCode. Then
I will read your post.

Thanks.

Perhaps at those prices you may want to consider ordering on from a store in .nl or .de. I've seen them here from picco.nl for € 55,- (incl.VAT) that is. Shipping from the Netherlands to the uk would cost an additional € 15,50. Total of € 70,50 would be about GBP 48 I think. German webshop mini-itx.de has them for €49,50 but shipping is €24,95. Germany is big, so possibly a better deal can be found. The UK is part of the EU so at least you wouldn't have trouble with customs or taxes.

talking about the store, i just noticed
http://amigakit.leamancomputing.com/cat ... e8f4f012f0
£133.99 Inc VAT ,in stock ;) how many did they get, i assume a regular order will be made if it takes off,no PicoPSU-60-WI 6-26V DC-DC ATX power supplys though perhaps they might get some or bulk buy.

also ,anyone know what is needed to use the
IRDA
for communication via infrared
with speeds from 2400 bps upto 4 Mbps
port?.

does a pre-made hi-grade (or simple 4-in-one even)infrared handset and/or keyboard exist that had all its buttons codes pre-set in an existing infrared (server) app ?, i assume there is something we can install in linux at least to use it?.
