Hi janosch, Appreciate the heads-up from someone who has been there before! Like you I was a bit surprised by how much the integration bled across subsystems. I like the egg analogy. > isolate the inverter and motor and make them believe

If you're interested then click the link in my first reply (which is to a newer post). The first video shows the working car reaching 8000rpm (about 80km/h) around six seconds after the accelerator was released. The second video

Hey! Post author here. I appreciate the insight from someone who's worked on this kind of thing formally, thanks. > Most likely what’s happening is that the creep torque is applying a constant small torque and the wheel sensors are

(Blog author here) You're spot on about the PLL stage, a few people on Reddit pointed the same thing out when I first posted it. Makes sense, although I still think it's interesting they added it internally to an otherwise (appare

I haven't tried any of their other products, but the iMX6 has a very large detailed technical manual (publicly available, not under NDA) and their Linux kernel trees are updated in public via git (presumably not everything is public bu

Freescale i.MX6 is a really nice platform. Shame it hasn't gotten broader traction, I think because it is moderately more expensive than its competition. Since May I've been using an imx6 based gk802 ($70 quad core "Android T

On the optimistic front, with a bit more digging I found this comment from Jerker Lindgren Götsten (Sony Mobile): http://developer.sonymobile.com/2013/06/13/were-opening-up-s... "The article was just a

Rather than "open sourced" all I see is "a bit open specced". Yes, the "hacker guide" has details of what chips are on the board, and how they are connected: http://developer.sonymobile.com/serv

I agree anyone seriously wanting to host that many photos will not want to split accounts, but FWIW statistics (current Pro feature) don't seem to be offered at all any more.

A number of things - the Z axis seems loose, the other axes skip steps (possibly the stepper drivers overheating), general issues with bed adhesion and warping. All common 3d printer issues, though some are exacerbated because I bought a ch

Google disabled access to /proc/config, which makes the process of building a vaguely compatible kernel all the more like guess-and-check. Is there really no .config in their GPL release? AFAIK compile-time config is a GPLv2 requirement a

FWIW I have access to an Eagle license but prefer to use Kicad whenever I can. In no small part because of the Linux app being clunky (also because Kicad is FOSS.) The annoying thing about using both is they're both similar-but-different in

Ah, right, thank you. I hadn't realised they weren't importing, just accessing. I'm not a feedly user so I don't mind but thanks for the link to the suggestion, good to see it's being considered.

by angusgr 14y ago
As far as I can tell Feedly has no OPML export feature, so if it eventually goes away it's a dead end for users. (Please prove me wrong, but I searched the site and also installed the extension to try and find one.)

I went and reread it, because I'd skipped the Nexus 10 section last week. At least the article describes the author's experience of holding the phone, if not actually using it. But I didn't feel my two questions were answered. The only part

I thought the suggestion was more that by producing just one variant for all markets/regions/carriers, Google/LG can leverage economies of scale to bring the overall price down. I haven't looked at the S3, but past Samsung models have had a

I totally agree that the Wired review wasn't all that it could have been. It did answer some of my basic questions though (like 'how does the battery life hold up?' and 'is it a lemon or not?') I can't really say the same for the Verge vide

A few weeks ago I would have largely agreed with the post, but recently I had a bubble-bursting experience. I'm currently in the middle of running an "Arduino for Beginners" workshop series at our local hackerspace. We have 25 attendees, 24
