Relay for use with USB 6009

Hello
I would like to control a Red Hat solenoid valve with the USB 6009 (Very neat and economical multifunction DAQ!). The USB 6009 has some digital output lines specified as TTL. Can someone advise me as to a suitable relay for a 120V AC valve with a 6Watts power consumption?
Thanks John Brohan

John,
Here is the simple solution to your problem. You can tie two or more ports together which to get higher current capacity.Make sure you use the 4.7k pull up resistor after tieing them together.Then output all the tied ports together as if it is one port. In your case if you need 20ma you can tie-up 3 ports for 24ma capacity.
Warning!!!! You have to turn all the ports ON or OFF at one time otherwise it may burn the board.

USB portable ext. HD for use with MBP & FCE????

I've seen a 120 GB USB portable external Seagate HD for $117. Would this be usable as a scratch disk for use with my MBP 2.0 and final cut express HD 3.5. Are there problems with using USB externals? FW external hd's seem to be a good deal more expensive.
This may belong in the FCE forum but I thought someone here that uses an MBP might have specific experience with it.
Thanks.
Maurice

I use a Seagate 160GB 2.5" 5400 external as mirror/scratch partitions and it works OK however, if I'm capturing at high res I usually write to the internal drive (that's running at 7200) to avoid any frame loss ...

I bought one recently very cheaply to use for general storage.
I found that FCE 3.0 worked perfectly and have been using it ever since instead of my FW HD.
HOWEVER, before you dash out and buy one take note that I have only been tinkering around and experimenting with comparatively short projects of no importance.
I strongly suspect that if I made a long and complicated film I might suffer - so pay the extra and get a FW HD !
Incidentally for normal storage purposes the USB2 HD takes over twice the time to move files back and forth. So even for non-FCE use the Firewire HD is twice as fast.

Opening & closing a solenoid valve using ni usb-6009

Hi,
I am very new to labview so any help would be apprciated.
I am using the ni usb-6009 as a power source for my solenoid valve. The valve is 12vdc but because the max output voltage for the ni usb-6009 is 5v i have designed and build an op-amp circuit which will amplify the voltage. I want to create a vi that will give a +5v digital output when a push button is pressed and 0v when the push button is off. What would be the most efficient way of doing this? Thank you.
Solved!
Go to Solution.

How much current does the solenoid draw? You say that you are powering the solenoid from the USB-6009 so just converting the voltage from 5V to 12V will not work - there is a current limit of 8.5mA on the 6009 which will not be enough to power the solenoid. You will need to use an external supply that can provide sufficient current to drive the coils of the solenoid and then use a transistor circuit to switch on the supply from the digital output of the 6009 (which can't draw more than 8.5mA).
Once you've got your circuit right, you can use MAX Test Panels, the Data Acquisition Express VIs or the DAQmx palette in LabVIEW to control the digital output. There are lots of examples in LabVIEW on how to do this

Tips for working with USB floppy drives

I was just wondering if anyone had any tips on working with USB floppy drives in Archlinux.
One thing I've noticed is that trying to use mkfs.msdos on my USB floppy drive directly doesn't seem to result in a usable disk (it's mountable, but reports that I don't have enough space available to copy files), but if I use the command on an image file the same size as a floppy disk and then use dd to copy the blank image to my USB drive I get a disk that's perfectly usable. Anybody know what the deal is with that or how I might be able to successfully format a disk in fewer steps (other than keeping the blank images around and just using dd to format the floppies, haha)?
Also, I'd like to hear any other tips or tricks any of you have for working with USB floppy drives. They just seem so much more usable under Windows as opposed to Linux, and that disappoints me a little.

jmetal88 wrote:Okay, thanks guys. I haven't figured out the issue yet, but you're helping me narrow it down. I decided to run a df -h command after each try of formatting the disk this time. I tried the low-level ufiformat command followed by a mkfs.msdos on the device, using a 720k disk, and df -h showed 700k free on the file system. It's just not making the file system large enough (I believe the file I was trying to copy over was 710k or so). When I run mkfs.msdos on a 720k disk image and then dd the image over to the drive, df -h shows 713k free after mounting the drive. Any idea why mkfs.msdos isn't filling out the full 720k on the disk itself, but is on the image?
I would assume this happens because (as far as I can tell from skimming through the source over the course of a few minutes) mkfs.fat only applies floppy size heuristics to fd and lo devices -- your USB floppy drive is treated as a hard drive, and that leads to less-than-ideal default parameters. Run
fsck.fat -v
on the more spacious filesystem to figure out what options need to be set when you attempt formatting an actual disk. Or just make things easier by keeping newly-formatted blank disk images on hand so that dd and (maybe) ufiformat are all you need to worry about.

Partitioning an ext. HD for use with Time Machine HFS+/FAT32

Hi, I hope that this question is not already answered somewhere - I did a couple of searches but couldn't find the answers I need.
I'm setting up an external LaCie 500GB HD (USB 2.0) for a friend, in order to use it for Time Machine backups (one partition) and as a non-backuped "data dump" (music / films etc.).
My plan is the following: Partition the ext. HD into a 200 GB HFS+ Journaled partition for use with Time Machine, and a 300 GB FAT32 partition for data (FAT32 to ensure the interoperability with PCs).
I have a couple of questions (apart from if you think the proposed setup is good in general):
1. The Time Machine partition would be used to back up a MacBook with a 120GB HD - in your opinion, is 200GB too much/enough/too less space?
2. In general, does Time Machine work with partitions on ext. HDs as seen in the setup I propose? (or should I use a drive with only one partition?)
3. are there any possible problems I might run into when partitioning a drive into two different file systems as HFS+ and FAT32?
4. Is it OK to use the Leopard Disk Utility for this or should I use another application?
thanks a lot for your answers!

Hi,
Could you please share the answers you found?
I'm going through a very similar situation...
Thanks!
Beto.

Best hard drive for use with Time Machine

Hi,
Has anyone determined what the best external hard drive is for use with Time Machine? Is there a particular one that works exceptionally well with Time Machine, or is it much of a muchness?
I'm looking for a Firewire 400 & Firewire 800 drive that STAYS ON all the time, and doesn't automatically spin down or spin up like the rubbish WD My Book drives do.

I can't tell you if it is the "best" hard drive for you to use with TM, but I'm quite happy with the 500 GB Buffalo Technology DriveStation Combo TurboUSB I bought recently. It is quiet, quite inexpensive for the capacity (I paid about $120 for one on sale at Fry's), & completely compatible with OS X & TM.
Best of all for me, it automatically powers down when my iMac sleeps. It also spins down after a time if the Mac's Energy Saver preference "Put hard disk(s) to sleep when possible" is checked; otherwise it remains spun up until the Mac is put to sleep or switched off.
It comes with "Turbo" USB & Memeo "AutoBackup" software, neither of which I installed. (The box didn't claim these extras came in a Mac version but both Mac & Windows versions were included on the CD.) Out-of-the-box, I reformatted the drive with the Apple Partition Map scheme & two partitions, a 160 GB one for cloning my internal drive & the rest for TM. The drive works perfectly for both uses & seems quite fast, as one would expect from a 7200 rpm SATA drive.

Compatible External DVD/CD Drives for use with MacBook Air

Hello all,
I'm after buying an external drive and was hoping we could put together a list of compatible drives as I've read on other forums that not all are compatible.
Please no links as they tend to expire but rather just list the make and model of the drives.
Thanks,
Jompet

It sounds like the features are working through the USB connection rather than the wireless connection since it is still not seeing the networks.
Everything points to a hardware failure since the steps provided through the private message did not work and the wireless test showed it had failed. Sorry.
You do have some options at this point.
If it is under warranty, either standard or extended, you can contact HP support at 1-800-474-6836 to have it serviced under warranty.
If it is out of warranty, you can still contact HP support to find out all the options and the cost of each option. However, it is my opinion that this money would be better spend being applied towards a new printer.

Hi Robert and welcome to Apple Discussions,
There are adapters available that convert micro cards into fullsize ones.
You will also need a USB card reader if you do not have one.

Internal SATA DVD burners for use with Encore

I want to buy a SATA internal DVD burner for use with Encore (on Windows XP). I've carefully reviewed the list of Adobe approved Encore-compatible DVD burners and the list seems to only include IDE and external (USB/Firewire) devices. Is there ANY SATA internal DVD burner that is certified to work with Encore?

Not that I know of, but since they appear as normal IDE devices, the procedure should be very much the same. It's more a matter of how reliably the driver for the burner translates the commands, I'd guess.

Laptop options for use with PrE 11 (£500 ish)

Hello,
I'm currently looking to buy a laptop that will allow me to edit various video projects on the move using Premiere Elements 11 (may upgrade at some point). This will serve as my main editing device until I upgrade my desktop, then serve as a portable editing station as I will be at uni next year as well as traveling a lot this year. I do a mix of animation and live action short film work using 1080p footage from my Canon 600D. I am currently looking at the £500 mark, I know it's tough to get a good editing laptop at that price, but I'd rather not spend much more. Currently I have found 3 options, and was wondering if anyone had any advice. The aspects of each laptop I am concerned about are highlighted in red
