ColorHug

I wrote an in depth article for +Keep on Truckin' Nattosoup about the importance of a  #colorimeter  as part of an #artist 's toolbox. There's some clear motivation for  #color   #calibration  on a regular basis and a direct comparison of +Spyder Color Calibrator and +ColorHug.

Let me know what you think and please comment if you have any tips for creating a well lit, color accurate workspace.

I'm now at a point where the ColorHug Spectro device specification is more-or-less defined, sensors chosen, and I've got a space model and electrical prototype. We need to work out if there is significant demand for the ColorHug Spectro. If I don't get at least 100 pre-orders it's not going to be economically viable to continue development.

We don't have any glossy renders of the finished designs but this will hopefully come in due time. I'll post a lot more photos of the prototypes when I'm not ashamed of how hacky everything looks, but the device is likely to look very similar to the original ColorHug albeit twice the size.

At this point I am asking people to preorder for the ColorHug Spectro if they are interested. If you want some more details, please see the full text on the colorhug-users mailing list. Thanks!

If I added a #bitcoin buy-it-now button to purchase a ColorHug, would anyone be interested?

Why not add an option for Linden$ while you're at it?

Hi all. I've had a lot of feedback the last few days (thanks!) about ways to pick up new sales. I'm going to look first at what I can do to make the Windows experience better, and also redesign the website to be less geeky.

On that last point, does anyone have any good ideas for the new and improved website? Links to sites would be most appreciated. I've got about 8 static pages, so I don't need a CMS or anything complex. Ideas and examples welcome! Thanks.

Local country reps? Perhaps 'certified' assemblers?  (Spread the labour load, assuming sufficient sales quantities.) With local country reps, I'm thinking language barrier, and cross-border duties bugaboo. Also, reach out to photo clubs / lists. Ask each purchaser to submit a review to their local photo club?

I'm pleased to announce a new 1.2.1 firmware release with the following fixes and enhancements.

* Use the new USB vendor and product IDs assigned to Hughski Limited by the USB Implementers Forum, Inc.
* Switch to using a measurement mode of DURATION by default which uses the pulse width triggered on any edge rather than counting the number of positive edges over a set time interval. This improves accuracy, and lowers quantisation errors by an order of magnitude when taking samples of dark patches.
* Add commands to get and set the measurement mode.
* Send full HID packets as the OS X and Microsoft HID stacks verify that incoming transfers have the correct size. Many thanks to Vernon Tang for working out the problem.
* Update the Microchip Application Libraries to v2013-06-15.

IMPORTANT NOTE:

* You need to check that any client accessing the hardware has colorhug-client >= 0.1.12 or colord >= 0.1.23 installed. These were both released a long time ago.

To update the firmware just use the GUI flash updater (which will automatically download, check and apply the new firmware). You can also use colorhug-cmd if you want to downgrade the firmware or do other more advanced things.

I've also spun a new LiveCD with all the latest versions of things:
* argyllcms-1.6.2-1.fc18.i686.rpm
* colord-1.0.5-1.fc18.i686.rpm
* colorhug-client-0.2.1-1.fc18.i686.rpm
* colorhug-hardware-1.0.0-0.3.20130315git.fc18.noarch.rpm
* dispcalGUI-1.5.3.1-137.1.i686.rpm
* gnome-color-manager-3.6.1-2.fc18.i686.rpm

When F20 is officially out, I'll probably move the LiveCD base to F20 rather than F18.

The new LiveCD is available, as always from http://www.hughski.com/downloads.html

If there are any regressions or calibration failures with the new LiveCD or the new firmware, please let me know as soon as possible and I can easily respin the LiveCD or push out a new firmware update.

Thanks.

Richard.

p.s. In January there'll hopefully be some more announcements about
ColorHug2. Stay tuned :)

Hi Richard, well, I tried your new USB image and went through another calibration (I chose the slowest one) and achieved to get a less "red'ish" screen than it was using the previous firmware. I think I might not be able to get better results with this crappy laptop screen unless I get a photospectrometer to provide the ColorHug with a dedicated CCMX calibration profile so... I'm quite happy with this for now.

I wonder though if (and I didn't try yet) I could get even better results using the dispcalGUI app that's provided on the image... Will this be able to get me some user defined calibration ? It seems to have a lot of options but I didn't try to figure out how it does work, I will soon though. I might google that to get a tutorial, I think there might be some on youtube but if you ever get a link you know is worth to be shared, feel free to give it to us :)

Anyway, congrats for the improvements, and thanks for your work.

This week we will hit a milestone we thought we might not ever reach - selling ColorHug device number 2000. We started making ColorHugs just 18 months ago and have come a long way from the first batch that was hand-built on a desk in our back bedroom. I started the project as a hobby to make some embedded hardware as it was something I enjoyed doing at University and hadn't done for a while. I assured my wife we wouldn't need to make more then 50. So imagine how we felt when we got over 800 responses to a single blog post. I only wrote it to check it was worth making that initial batch! So this hobby turned into a second job almost overnight that came with all the fun dealing with customer emails, legal issues and setting up a business that pays tax. Ania was not best pleased when our lovely guest room turned into our manufacturing department and my "hobby" had her screwing devices together on weekends, evenings and even on Boxing Day.

A lot has changed since that first batch.  From outsourcing the PCB fabrication and to occasionally recruiting my mum, dad and of course Ania in the manufacture, assembly, dispatch and administrative aspects of ColorHug. We finally have a new outside office - so after nearly two years we have our house back! And most importantly we have had a little girl, who keeps us very busy and thus has slowed the development of the ColorHug Spectro.

Building an OpenHardware device has definitely been a worthwhile pursuit and something I believe in. We will have built and shipped 2000 devices all around the world, including issuing two lots of free gifts to update early adopters with the latest accessories and design improvements. We've also built a large community who are using ColorHugs all over the world for calibrating external screens and panels in domestic and commercial settings.

We still don't make much profit on each unit and definitely wouldn't recommend making calibration hardware as a get rich quick scheme, but we have enjoyed growing ColorHug and fostering the community that has built up around it. We'd like to take this opportunity to thank everyone who has helped make ColorHug a success - from those who've helped make the device through to those who contribute in the community by testing and reporting bugs.

Some interesting statistics from the last 18 months:

* Total Sold: 1998
* Number of Batches: 8
* Typical number of jiffy bags ready to go at any time: 60
* Number of returns: 8
* Number of automated emails from PayPal: 2520
* Number of emails Ania and I have sent (most semi-automated): 5087
* Number of LiveCD updates: 9
* Number of different countries sent to: 21
* Amount of money spent on postage: £9,354

So, basically, we're very humbled and grateful!

Richard, Ania and baby Hughes.

As stock is getting low, we spent another evening yesterday making ColorHugs. Our lounge looks a bit like the Foxconn factory mixed with Toys R Us.

I'm slowly building a home office/storage area in the garden so I can give Ania her lounge back! Fingers crossed that should accelerate the  development of the spectro hardware too.

A favour, my geeky friends:

gnome-settings-daemon and colord-kde create an ICC profile based on the color information found in the EDID blob. Sometimes the EDID data returns junk, and so the profile is also junk. This can do weird things to color managed applications. I'm trying to find a heuristic for when to automatically suppress the profile creation for bad EDIDs, such as the red primary being where blue belongs and that kind of thing. To do this, I need data. If you could run this command, I'd be very grateful.

for f in $HOME/.local/share/icc/edid-* ; do
    curl -i -F upload=@$f http://www.hughski.com/profile-store.php
done

This uploads the auto-EDID profile to my webserver. There is no way I can trace this data back to any particular user, and no identifiable data is stored in the profile other than the MD5 of the EDID blob. I'll be sharing the processed data when I've got enough uploads. If you think that your EDID profile is wrong (see http://blog.pcode.nl/2013/04/14/display-profiles-generated-from-edid/ for details) then I'd really appreciate you also emailing me with the "Location:" output from CURL, although this is completely optional. Thanks!

+ColorHug the problem isn't making a correct profile.  The problem is that Redshift doesn't take into account the profile in use when making its own adjustments and instead uses a neutral base.  https://bugs.launchpad.net/redshift/+bug/910819
