Air quality monitoring for 3D printer

Hi everyone.
I'm trying to find sensors to monitor air quality which work with Labview.  The 3D printer we are using has a risk of contaminating the air with particles, fumes etc.  If I could monitor the air particles, O2 and CO2 levels I think this would be a good start to making the print room safe (and real time monitored).  If anyone is interested you can have a look at what we're doing here

Wes,
A quick search for "particle size monitor" found several devices which might be suitable. Particle Measuring Systems. Chemtrac. Dandong Dongfang Measurement & Control.  I have not used any of these but they will give you some ideas where to start. At least one of them communicates via RS-232 so intrefacing to LabVIEW should not be difficult.

  • OSX-software for USB Air Quality Sensor ?

    I'm trying to find MacOSX-compatible software to read the data-output of the iAQ 77-0900 Indoor Air Quality Monitor USB-stick by AppliedSensor.
    http://www.appliedsensor.com/products/indoor-air-monitor.html
    This product is sold under variuos names and brands, e.g. :
    Volcraft CO-20 USB
    MSR CO2 Air Guard USB
    Butterfly Indoor Air Monitor USB
    Dwyer AQStick model ASQ-1
    eNasco Indoor Air monitor USB
    FRAKTA co2-Air Gard USB
    Sentinel-Haus Institut RaumluftWächter
    ...but they all have only one piece of compatible software : AirMonitor for Windows-PC
    I've not been able to find compatible sotware for OSX, but a similar & compatible piece of software does exist for Linux :
    http://code.google.com/p/airsensor-linux-usb/wiki/About
    Can anyone help me to read-out the data from the Air Quality Sensor USB-stick from an Intel-Mac ?
    Thanks !

    Hi Sebastiaan,
    Thanks for your reply and your directions.
    I am not a developer, and I do not like messing around in the Terminal.
    So when I got an error-like warning when I entered the first sudo-command, I did not procede with your directions.
    But... if you give me a link where I can download the app you've compiled, I'm willing to test it.
    (I have xCode and XQuartz installed)
    Furthermore... I did do some other things that might be of interest :
    1- I found an MacOSX-compatible Java-app called "DataExplorer", that might do the trick, but I couldn't get it to run properly :
    http://www.nongnu.org/dataexplorer/#downloading
    2- I managed stand-alone apps using both WineBottler and WineSkin ; they both run, but refuse to see the USB-stick when it's pluged-in...
    3- I was also able to install the windows-app on WinOnX, but I get the same error there... the app runs, but it doesn't detect the USB-stick either...
    Thanks for your help !

  • I've got a MacBook pro 15' running 10.6.6. I want to use an external monitor for my graphic design work running Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing.

    I've got a MacBook Pro 15' running 10.6.6. I want to use an external monitor for my graphic design work using Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing. I also tried a Mini Display to VGA lead and that wasn't much better. I tried all variations of resolutions in System prefs - Displays but nothing helped. Am I getting something wrong? Thanks all.

    In addition to pixel density, you are up against the translation driver card in the TV.
    If you read the fine print of computer-resolution-capability in the TV user guide, you will see a chart as tall as the manual page.  At the top is the smallest resolution capable, at the bottom is the full use of the 1080p in the TV.
    Mac falls into the top 25% of the page, maxing out at 1366x768 often.  This is because the TV control card is expected to do too much of the work, but is not designed for computer-monitor processing.
    I looked at the resolution charts on 2 TVs before deciding to buy a 1080p LCD monitor that has a TV interface/connector.  Computer monitor first, TV second.  But the thing is only 27 in.  Good thing TV is not as important to me as it is to others.

  • New iMac as a monitor for XP Bootcamp on an old Air

    Hello all -
    Need your assistance getting an accurate answer on an Apple related issue. Trip to the Apple store (including speaking to 5 employees, 2 of whom were genius bar staff) did not provide the clarity/certainty I am after. More on that later.
    I have a work issued 11 inch Air (running XP via Bootcamp). I cannot boot the Apple OS, nor make any changes to the XP environment.
    My Air is an "older" model: 11 inch with mini-display port, not the "spark" firewire port, but same size of course.
    I am thinking about buying an iMac, which would be dual purpose...second computer and monitor for my Air. But I am unsure if an iMac will do this smoothly with my Air (or which model can or can't do it).
    Let me tell you what I have done:
    - two visits to the Apple store
    - conversation #1 (yes, it will work...21 or 27 inch...no mention of firewire or mini-display issue, no issues with XP on Bootcamp)
    - conversation #2 (yes, but 27 inch only....it is ok that Air has mini-display and is using XP via Bootcamp)
    - conversation #3 (yes, but you need to buy an old model iMac that still has mini-display port, not firewire)
    - conversation #4 (no, it will not work with Bootcamp with any configuration)
    - conversation #5 (yes, will work with any 27 inch model...use mini-display to VGA (from Air), use firewire to VGA (from iMac), and then use a male-male VGA to connect the two
    Apple has a knowledge base article on the topic, which offers yet another view. However only speaks to 2009 and 2010 models. I am unable to find a similar entry for current iMac models.
    Using a 27-inch iMac (Late 2009 or Mid 2010) as an external display
    Apple won't test any of this at the genius bar (well, the genius I had - conversation #4 above).
    Any thoughts?
    Thanks
    Dave

    Are you talking about the Thunderbolt port on newer Macs? If so, see http://support.apple.com/kb/TS3775 & http://support.apple.com/kb/HT4617.
    It appears you cannot use Target Display Mode with one of the newest Macs unless the other Mac also has a Thunderbolt port, & that only Windows 7 supports Thunderbolt, not Windows XP.

  • MacBook Air with MiniDP as external monitor for 27" iMac

    Hi,
    I just found out, that the new iMacs can be used as external displays for MacBooks with MiniDP.
    Now I'm considering to buy an 27" iMac, but I've one question:
    As my MacBook Air is much slower than an iMac, I was wondering if I could get my MBA (or any ohter MB) in Target Display Mode, with the Command/F2 key combination?
    I know about ScreenRecycler, but I want something that works right out of the box;)
    As you can connect 2 iMacs together and use either one in Target Display Mode, I hope the same will be possible with an iMac and an MBA
    Thank you

    You can put the 27" in target display mode to act as a monitor for the MBair but the reverse is not true. You can't make the MBair a monitor for the iMac 27".

  • Can I use my Imac as a monitor for my Macbook Air?

    Can I use my iMac as a monitor for my Macbook Air?

    Without any knowledge of the year machines you have it's impossible to answer that question. iMacs adn MBA's have been around for many years now so we have no idea of the exact specs your machine have. Remember when posting you need to be complete and paint a picture for us as we aren't there to look for ourselves. Your question should be  posted something like:
    " I have a 2011 27" iMac and a 2009 MacBook Air, can I use the iMac as an external display for my MacBook Air?"
    BTW what you are referring to is called Target Display Mode. Apple does support that on some 2009-2011 iMacs. You can find additional information at:

  • Print quality tip for Epson printers with wifi

    Just wanted to post a resolution to a print quality problem we were having with an Epson Artisan 730.
    I discovered that if we cnnected via wifi the printer driver used offered much lower quality and fewer options then we were used to under Snow Leopard.
    When I connected via USB the print dialog offered addtional options and more control over quality and color management.
    Seems very strange to me so i thought I would point it out.
    Jeff

    I just had to go into system preferences for the printer and click on the printer and then click on sharing preferences and type in my computer name.  Then turn off the computer and turn it back on again and the printer now WORKS.  Amazing.
    That solved the same problem for me also.  I had already gone into Time Machine and put back the old Epson files that were changed by the update, but that didn't fix the problem.  Typing the computer name fixed it.

  • IMac 6,1 as monitor for Macbook Air 11'' ?

    Hi everyone,
    I have an old iMac "core 2 duo" 2,16 24'' (also know as the iMac 6,1), with OS version 10.6.8 which is getting old. I would like to use it as a monitor for my Macbook air 11'' (with the latest Yosemite).
    1) Is it possible?
    2) What do I need?
    I know it is possible with newer versions of the iMac but I'm not too sure mine can do the "cmd + F2" thing. And before buying expensive cords to link them, I want to be sure it can be done
    Thank you very much for your time and your help!!

    Unfortunately your iMac is too old to use Target Display Mode Target Display Mode: Frequently Asked Questions (FAQ) - Apple Support
    You might look at Screen Recycler http://www.screenrecycler.com/ScreenRecycler.html it may or may not meet your needs but it's worth a try.

  • Print quality preference for HP 6500

    The default print quality preference for the HP 6500 seems to be "medium" which obviously uses more ink. how does one rest the preference to "one star" or draft quality print?

    Please read this post then provide some details. What operating system?

  • Using 27'' iMac (2012) as extended monitor for MacBook Air (2012)?

    Hi all, I'm trying to find a solution how to use my iMac as the extended monitor for my MacBook Air. I saw the video on YouTube >> http://www.youtube.com/watch?v=8bVOssjlsGY << but I am not sure if it is real or fake. I have checked the forums here and other sources, but I haven’t seen any official statement about the possibility to use thunderbolt cable for this purpose. Do you have any experiences with that? Or can you advice please?

    Yes, you can use the 27" as a monitor with Target display mode.  Just attach the two with a Thunderbolt cable and press Command F2 on the iMac.  It will become a secondary monitor for the MBair.

  • When i ask my macbook air to print it tells me it is looking for my printer it takes several minutes before it finds it and then prints, why is that as my wife is connected to the same printer in the same way (bluetooth) and hers prints straight away

    As per my question, when i ask it to print it tells me it is looking for my printer this takes several minutes before it prints.  my wife is in the same room using an imac also using a bluetooth connection to the same printer and hers prints immediately.  why is this.

    Perhaps you could try this to resolve your issue:
    *How to Reset the Printing System*
    1. Open System Preferences > Print & Fax
    2. Move your mouse over the Printers list
    3. Hold down the Control button and click the mouse (or right click if supported).
    4. Click "Reset printing system ..."
    5. Restart your Mac
    This will remove your print queues but not your printer drivers. So you will only need to add your print queues again.

  • 'Maximum' Quality Setting for Previews

    Dear Adobe,
    Aside from 'Low', 'Medium', and 'High' settings for standard-size previews, please add a 'Maximum' quality setting (equivalent to 10-12 quality setting for JPEGs in Photoshop).
    As standard previews are generated for imported images or for new edits on images already in Lightroom, sometimes low quality JPEG previews are generated. These previews exhibit color banding & macroblocking artifacts typical of JPEG files (especially in dark areas). Since these previews are used in the Library, Slideshow, Print, and Web modules, it's pretty darn annoying & distracting to stare at low-quality renditions of our images. Switch to Develop module, and a fresh new image is rendered on screen; therefore, these JPEG preview artifacts are not visible in the 'Develop' module.
    Two fixes to this problem:
    1.) Add a 'Maximum' quality setting for previews that Lightroom generates
    2.) Fix it the Aperture, Bridge, iPhoto, 'every-other-software', and your own 'Develop' module way: display the precached preview first, while rending a fresh view of the image in the background... display that when it's ready.
    Here's a forum where I've discussed this previously:
    http://www.adobeforums.com/cgi-bin/webx?128@@.3bc33a73
    Here are examples of the low-quality previews generated by Lightroom (when 1680 'High' setting is used for previews):
    http://web.mac.com/rishisanyal/iWeb/Homepage/Macroblocking.jpg
    http://web.mac.com/rishisanyal/iWeb/Homepage/Library.jpg
    http://web.mac.com/rishisanyal/iWeb/Homepage/Library_vs_Develop.jpg
    And if you are using a well calibrated monitor, then look at the macroblocking in the black wool coat in this image (please use a color managed viewer, else the coat will just look black and you won't see the blocking):
    http://web.mac.com/rishisanyal/iWeb/Homepage/Lightroom_JPEGblocking.jpg
    We photographers have discerning eyes. It's painful to see this terrible renditions of our precious images... and to have to switch over to the 'Develop' module *just* to get a high-quality rendition of our image? And meanwhile watch slideshows with low-quality versions (previews) of our images?
    Sounds pretty unacceptable to me.

    So, I'm pretty much convinced now that the problem with low-quality LR previews seems to be mostly isolated to the previews that LR generates after you make edits in the 'Develop' module.
    Upon first import, this image looked fine in the 'Library' & 'Slideshow' modules. After making some edits (color, tone, etc.) in the 'Develop' module, I ended up getting this hideous preview in the 'Library' & 'Slideshow' modules:
    http://web.mac.com/rishisanyal/Lightroom/07-0310_BandingBlocking.jpg
    You people with LCDs will be able to see the JPEG artifacts better than those with CRTs, since LCDs tend to be sharper.
    So, the obvious question is this:
    Does LR, when *re-generating* previews for edited images, ignore the quality-setting for JPEG previews (which I have set to 'high')??

  • Managing colors for perfecct printing not working

    Hi all,
    I think I have tried everything and all my prints look exactly the same (different from what is on the screen) so if anyone could help, it would be great! (This is a thank you pic for all the people who came to my wedding!). In all the of pictures, it seems like there is too much yellow and they miss some of the saturation.
    For this specific shot, the camera was a Digital Rebel XT. My printer is a Canon IP4300. My screen was calibrated with a Spider Express2 using a gamma of 2.2. Oh, my screen is a 23'' cinema display.
    First try:
    I used the Spider2Express color profile for my screen, in aperture I setted the color profile to system managed and in the printer setting, I disabled the color correction in the color option tab.
    Second try:
    screen color profile: Cinema HD
    Aperture profile: system managed
    disabled color correction
    Third try:
    screen color profile: Spider2Express
    Aperture: Canon IJ Color printer profile 2005
    disabled color correction
    I also played with the black point compensation and it didnt change anything in the output.
    Also, when I play with the onscreen proofing I cant see any changes between these profiles: spider2express, Cinema HD and the oen from the printer. If there is one, it is too small for me to notice.
    Finaly, the print preview all look exactly as what was on the screen.
    I really dont understant where the problem can be so any help would be great!

    Hi Alan,
    I'll give it a bash to help,
    firstly you'll have calibrated your monitor with the spider express and it'll have created a profile. Your display should be set outside of aperture to use this profile. Go to system pref's, displays, select the colour tab and select the profile spider created. This gives your display the profile to use in all applications.
    Next If your using photo paper there may be a profile for the printer / paper combination from the paper manufacturer, check their web site. I use Ilford and have downloaded the profile for my Canon i9950 & classic pearl and installed it. This profile then appears in the view, proofing profile within aperture. You should not really use on screen proofing untill after you've made all your image adjustments and then finally use on screen proofing to check for posterisation and colour saturation.
    So now on to printing, Perhaps the profile you've downloaded suggests a default paper type to use such as (seeing as it's a canon printer) photo paper plus glossy or photo paper pro and if to use black point compensation or not. We need to keep these settings in mind when we enter the print menu. Best thing to do is copy the sample single image preset and rename it to the paper type and size your using. Then in the print settings for that newly created profile you'll see a button for printer settings, select it and you'll be presented with another menu for printer settings. In the 3rd drop down menu form the top select colorsync, color conversion = standard and quartz filter = none.
    then select quality and media from the 3rd drop down and select the recommended paper type in the profile you downloaded (it's normally photo paper plus glossy) and change print mode to top quality photo.
    Next again in the 3rd dropdown select colour options and set colour correction = none.
    Next go to special effects and make sure no options are selected and click done.
    You're back in the print menu, select the paper size you are using and the orentation. In the colorsync profile select the profile name for your paper and you may click black point compensation if required. Note the gamma setting usualy set at 1, and your print resolution, I normally have use best DPI selected. Now save this as the renamed paper type you copied at the start.
    Next is to run off a test print making sure you select this new paper settings in the print window and see how it looks. If you notice it's a little dark go back and adjust the gamma to say 1.15 to 1.20 and try again. Don't forget to save your adjustments.
    As you use different papers and sizes you create these settings and just simply select the required ones for the print size / paper type your using at print time.
    This is how I work and it gives good results. Also if your getting dark results all the time consider reducing the lumanance of your display from a recomended 120 / 140 Cdm to something less like 90 / 100 cdm. The apple displays can run a little "bright" for printing giving the impression of dark prints when compared to the screen.
    Best of luck
