well um i'm here.. an entire week early :) long story, but having booked the train tickets and hostel, nobody actually told me i was on the wrong day because of two separate and unrelated pieces of confusion / misprints! i decided rather than go back home to simply stay a week, having brought everything - soldering-iron, ruler, pliers, scissors, laptop, the works - with me all this way. 15kg suit-holding bag on wheels.... and in my infinite wisdom i decided that it would be an interesting … [View More]

libre laptop 3d print run 90% done
by Luke Kenneth Casson Leighton 18 Jan '16

18 Jan '16

holy cow there are *twenty five* separate parts in the laptop's casework. that's just nuts. if someone had said to me, "yeah you're gonna be making a 3d printed laptop, you'll need to do it in 25 separate parts" i would have said, "naah, you're having a laugh - surely it doesn't have to be that complex" which in the past has been my cue to run like hell from any project whenever someone uses the phrase "surely it doesn't neeeeeed to be as complex as alll thaaaat"... :) anyway i'm nearly done … [View More]

laptop casework, jz4775 cpu card, fosdem 2016
by Luke Kenneth Casson Leighton 15 Jan '16

15 Jan '16

hi folks, right. i've moved on to re-printing the 3d casework of the laptop, most of that will be in higher-temperature ABS. i'm about 50% the way through that, so another 2-3 days and i'll have an assembled prototype. some bamboo 1.5mm plywood panels are arriving from a U.S. supplier (the only one in the world that sells online 1.5mm bamboo!) are arriving shortly. the jz4775 cpu card, it turns out that digikey sent the wrong PMIC. bizarre story: the ACT8600-QJ162-T became popular in the … [View More]

EOMA68-jz4775 first usb-loader hello-world success
by Luke Kenneth Casson Leighton 06 Jan '16

06 Jan '16

http://rhombus-tech.net/ingenic/jz4775/news/ yippeee! the jz4775 cpu card didn't blow up, instead it announced itself on the usb bus, and i was able to modify a CI120 usbloader i found, to upload a UART0-based "hello world" program. next phase would be to initialise the DDR3 RAM, then compile and upload u-boot into DDR3 RAM and execute it. all very exciting

EOMA68 A20 Libre 15.6in Laptop prototype PCBs, first fully-functioning boot
by Luke Kenneth Casson Leighton 04 Jan '16

04 Jan '16

http://rhombus-tech.net/community_ideas/laptop_15in/news/EOMA68_Libre_15.6i… hardware all fully-functional, despite drawing too much power during the audio test. power is currently hard-wired to a temporary location that will be sorted out when PCB3 is replaced with a board that uses the TI bq24196 - a much better PMIC that is properly compliant with the USB-OTG Power Specification. this is really exciting as it will not be long before a fully-assembled prototype is up and running. l.
