Craig, How is the process of deploying the gumstix clusters? Any schedule plans? I'll take a few days off for the new year holidays, but I'll be back soon. Until there, if you have news, please share. It has been a while with no one commenting on that matter. :-) Cheers, Alexandre |

Sorry -- this is pretty much my fault. We have one cluster in the hands of the UK site operator (who happened to be visiting San Francisco so I just handed it to him in person). The other two (Berkeley and Brazil) haven't been sent out yet, because, well, I guess I didn't get around to it yet :( That's a pretty lousy excuse, so I'll try and get them shipped out this week.

Hi - it will be full-steam-ahead on the one we are building - from next week... hardware/software/net set up may take a week though :-( Happy New Gummy Year everyone!

Hi, We're making up the power & case for the gumwad - so far we think we'll run them all from one regulated 4.5V mains adaptor (any reason for 5V?) and a bunch of plugs (2.3mm is the digikey one on the Wiki but is it really? RS sells 2.1 or 2.5mm plugs here!) I have an ethernet switch which will allow them to all be plugged into one wall socket which will be in our DMZ. Physically I like the idea of mounting them packed vertically on their long side but there are issues with the mounting holes.. I'll see what the workshop says. I think six will emit enough heat that they don't want to be enclosed completely. Any ideas? Cheers Kirk ps: next step is how to build a native compiler! - http://www.ecs.soton.ac.uk/~km |

RS sells 2.1 or 2.5mm plugs here!) 4.5V should work fine; if you could go down to 4V or even 3.6V you'd probably get a lot less heat generated on the etherstixen. As far as plug size, I think it is 2.3mm -- but I suspect that if 2.5mm fits it'll hold in place just fine. The socket is spring-loaded so probably has room for an extra 0.2mm in there. > I have an ethernet switch which will allow them to all be plugged > into one wall socket which will be in our DMZ. > > Physically I like the idea of mounting them packed vertically on > their long side but there are issues with the mounting holes..

The etherstix probably will get warm -- I think if you could make a "chimney" hole at the top of the case, and a reasonable opening on the bottom as well, air flow through would be sufficient to keep things cool enough. Again, lowering the supply voltage would also help here. > Any ideas? > Cheers > Kirk > ps: next step is how to build a native compiler! That part should be pretty easy -- make gcc_target should work in the buildroot. Then distcc *ought* to be easy, though I haven't tried it yet. C |

yep - saw that one Gordon - I've ordered some right angle per-made 2.5mm from RS - we don;t use Digikey so much here - it will save space AND soldering :-) looks like 5V though - or a variable PSU which is less reliable (I think)...
