ah that's neal. yeah i'm deeply impressed by neal's entrepreneurial spirit. the pengpod 700 and the 1000 went down extremely well. he's now doing a crowdfunding project for the A31-based "uber"-tablet. i didn't want to alarm/discourage him, the fact that he's trying _at all_ when so many others are going "yeah it'd be nice IF..." is just amazing in itself... _but_... the A31 should instantly ring alarm bells for anyone not just in the free software world but even in the business world because it has powervr graphics. allwinner have now learned that lesson because the A31 even 6 months ago was considered to be a flop... but they've already taken that in their stride and moved on. > And the KDE plasma tablet is about to be announced (so I hear).

Probably a couple of months or so, so > definitely not 'available today'. that'll be me doing the hardware for that. i screwed up the revision 1 _and_ revision 2 so am having to do revision 3 myself. this is probably a good thing because no matter how good any 3rd party designers the fact that so much of the design information is in my head means that bringing anyone else on-board is just... well... we already screwed up rev1 & rev2 :) anyway, yes: i can't say "how long" either. i should be done the rev3 PCB layout within a day or so. if anyone knows anyone who can do PCB board design reviews i reallly need help here, even just basic advice (which at this stage is all that i can expect). factory's already alerted to expect the gerbers. buyers underway for components. case manufacturer received early prototype, expecting PCB... so many details. then after that we need to do the firmware! the design is basically using an ATSAM4S (not an STM32F as originally planned). that has USB2 (unlike the STM32F103) and it has a dedicated PIO port up to 48mhz which can be used for anything up to a 720p CMOS camera (woow!). the ATSAM4S will handle camera, backlight, power management, RTC and so on. any spare pins i've brought out to an optional 24-pin header, which includes one more USB, I2C, 2 DACs, 2 ADCs, 5V and an SPI port. there's a bit more from the multiplexing of the ATSAM4S but that's basically it. anyway anyone who'd like to follow along, it's all here: http://rhombus-tech.net/community_ideas/kde_tablet/news/ > I'm holding out for one of those as it has been designed to be > free-software all the way through and (mostly) open hardware. ... and you already have one of the very first EOMA68-A20 CPU Card samples so you'd only need the chassis, yaay :) next up will be a laptop, and that's easier than it looks. the hardest bit - the PCB design - will basically already have been done by then. i'm already designing the rev.3 PCB so that it can take a 9in (ipad) 1024x768 LCD, and it also has a SATA and an Ethernet connector on it. but that's a way off. l. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
