  1. This is an unofficial 'heads up' for anyone interested in working in central Virginia. The position is not officially open yet, but when it does open (hopefully in a few days) we are going to need to act fast. For now, just PM if you are interested. LabVIEW skills are important, but we also need someone with excellent 'general purpose' technical abilities. You will be the jack of all trade and master of them all. Everything from electronics to hydraulics, RF, analog, and digital - you name it we do it. I really can't give to may details on the web, but this position has been one of those 'dream' jobs for me. Hopefully it will be for someone else now as well. Good luck! John
  2. Hey, I've been on LAVA for years and just noticed your avatar for the first time. (Hello, my name is ...) I think that is the best one on the forum!

  3. In hind site, I could have grabbed the latest Device Driver DVD from the Developer Suite. (dooh!) Still... 311MB for a USB - Serial converter? Then about 20 minutes for installation time? Is it really necessary?
  4. Am I missing something? Do I really need need the entire 311 MB NI Serial software just to install drivers for the NI USB-232 device? I know it comes with drivers on CD, but by the time I ever get around to using the hardware I've purchased, the drivers on CD are out of date! (perhaps I am just spoiled now that Windows 7 automatically finds and installs drivers for so many of the other devices we use)
  5. Just got around to reading this. As a former Canadian turned American I find this absolutely hilarious!
  6. Ok ok. I did it. Now following @lavag and @niweek on twitter! didn't make it to lava bbq tonight. Anyone else left behind?
  7. At the LAST minute the trip was approved! so I am writing this from the bar at the Iron Cactus! wonder where everyone else is? (maybe if I was on twitter I would know?)
  8. I STRONGLY recommend Single Board Systems for their top quality hardware and excellent support. You will not go wrong using them.
  9. I had given up all hope... then I heard a rumor... now I am crossing my fingers... (the suspense is killing me!)
  10. Depending on your time/budget constrains it may be sufficient to max out your computers memory (4GB), and eliminate unnecessary programs from running. (How much memory are you running right now?) Either that, or upgrade to a 64bit machine with 8GB or more of memory (you would have to use a 64bit version of LabVIEW). However, there really should be a way to overcome your problems without throwing hardware at it.

    AC Power Meter

    You may be in the range where you need to use a Current Transformer (CT). Essentially a device that outputs a voltage directly proportional to the current. You can then use a relatively inexpensive voltmeter to monitor your current.
  12. The circuit you are describing would look like this ... ------------|>|------------- | . . . . . . . . . . . . . | | . . . . . . . . . . . . . | ------------|>|------------ | . . . . . . . . . . . . . | | . . . . . . . . . . . . . | ----------- (-8V+)-------- Then, one diode may break down before the other.
  13. Perhaps its my Canadian roots, but I'm loving it!
  14. We use a very similar mouse here at work. Once you get use to that scroll wheel, all others seem very cheap and limiting. The keyboard looks great!
  15. Hi Veronica, LAVA is perhaps female friendly and Canadian tolerant, but I'm not sure if we should tolerate someone from McGill! (I'm from Queen's and could resist the chance to bring our friendly inter school rivalry onto LAVA! )
