ColorHug

Shared publicly  - 
 
 
For the last couple of years I've been working on an OpenHardware spectrophotometer design. This allows people to measure spot colors, for example measuring paint or ink swatches. I spent a good chunk of last night learning OpenSCAD and now have some actual designs for the new enclosure. I've got one huge prototype that's working really well, but there's still a lot of work left to do.

From a physical point-of-view it will look a lot like a "chunky" version of the ColorHug2, with a few more holes in the bottom to illuminate the sample with a broad-band illuminant and also an optional UV source. This means we can profile the florescent properties of paper, which is a major failing for a lot of the spectro hardware that exists already.

This device isn't going to be cheap, but it will be open hardware with all free firmware and drivers. See this page for more information: http://www.hughski.com/colorhugplus.html

+Ian Tester I already have all the punches for mini-USB, tooling for this kind of thing is super expensive. The illuminants only add a few pounds to the price, the biggest component cost by far is the sensor itself; in one-off quantities the sensor alone is £300, so I need to buy a large quantity in one go to actually make it possible to do sensor+everything_else+NRE+postage+risk for £300.

+ColorHug thank you so much for your answer! I am very sorry to trouble you again, but you are the best one to know. So if I were to calibrate R+GB LED Back lit screen  I should be fine? Does it work well with IPS and PLS matrix based screens? Yes I would be using dispcalGUI. Currently aim is to calibrate Dell XPS L502X, Lenovo Y50-70, Asus Zenbook ux305, Samsung 27" S27D FHD, PLS and possibly a Dell Precision M3800. Would Colorhug 2 handle it without the need to do with cmmx files etc? Thank you so much for your time!

Everything has arrived for the first proper batch of the ColorHug2. The new PCBs are black and look stunning. I've spent over £8K on this batch already, but there's already a small waiting list for new ColorHug2 devices and everyone that I've shown the new high speed sample mode to has been quite impressed.

If you're interested see http://www.hughski.com/colorhug2.html for more details. It should be a couple of weeks before the first populated boards start coming back and then Ania and I have a lot of devices to assemble.

Yes needing CCMX and having to go choose one without having any idea was a big flaw.

+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.

Just submitted my talk to #LGM about ColorHug Spectro, an OpenHardware spectrograph that might actually happen.

There are 20 original ColorHugs left in stock. When those are gone, we'll be switching 100% to ColorHug2 production.

As I know a few people have deployed CH's into production environments, this might be the last chance you get to purchase a spare :)

I also have one that I can sell - I am from Poland if anyone is interested. I am unable to get it working properly, colors after calibration are pink, I have tried a few times and have given up...

I've only got about 10 ColorHugALS modules in stock. I'm in two minds about making another batch of these devices.

I don't actually make any profit from them whatsoever (I've been sending out free ones to relevant GNOME developers), and I probably only sell one a week. I've not actually received many bug reports or feature requests, although I do see from the LVFS that people actually use them as new firmware is being downloaded fairly regularly. I could easily spend another evening making another batch of 50, but I'm wondering if it's worth my time...

You caught me. I only did a very short test when receiving the device but never took the time to do some more testing and giving feedback, sorry. (I'm working mainly on CentOS 7 and not Fedora 23.) However, I just did that, and gave you feedback by mail. As summary I really like the device, but it's too fast/sensitive for me. I guess some averaging over a longer period of time (for example 2 minutes) would help.

1000 ColorHug2 PCBs just arrived. It'll take a few weeks to get everything built, tested and packaged up, but still exciting!

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 :-)

Just purchased the ColorHug 2 for testing.  Sounds fun.

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.
