Interested in some prototype hardware? We're probably a couple of months from a real release announcement but I know some people want the new device for one reason or another. 19 devices left :-)

This is using the very experimental ColorHug2 hardware, but might be interesting for somebody in the future.
 
Another evening of hacking...

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?

+Patrick Outhier The "ColorHug Display Analysis" is a tool designed for the ColorHug2 (unreleased hardware) not the original ColorHug. Could you explain a little more about the systems that did not work with the LiveCD please? Thanks.

Ania and I spent last evening making the last ever batch of ColorHug colorimeters. We've now got 85 in stock, which should last the next 3 or 4 months. After that we're going to take a few months break, and then start working on the ColorHug2 colorimeter.

This isn't the fabled ColorHug+ spectrophotometer (which I'm still working on) but it's just a better colorimeter. The size, shape (and fingers crossed, price) will be the same as the original ColorHug, but we'll have a much more accurate (and expensive) sensor from MAZeT. The new sensor has proved itself in the prototype to be stable and accurate. The new device will, if all goes to plan also have an integral 1/16th degree temperature sensor and some much needed external DMAable SRAM so we can do things like latency, refresh rate and flash measurements with the new design, even if some features are not ready for product launch.

The best bit? This device shouldn't need a correction matrix for most screen types.

inviting the Osborne effect?
My Colorhug (no 888 I think) also produces a distinct red tint.

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 :)
Download a Live CD to try ColorHug on your computer, or fetch firmware and Linux client source code.

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.
