aiiii
I'm a dinosaur, great stuff IC

Re: It begins
 

Excellent! Look forward to seeing this produce results and evolve.

Re: It begins
 

Someone's got money...

Looking forward to see it run!

Re: It begins
 

Thank you

And Bill, if your a dinosuar your a damn smart one :p
Without your guidance and advise Id still be in phase one and have wasted three times the money on antiques as I did before you started to clue me in :p


someone worked 3 x 16 hours back to back shifts at Conoco per week for 6 months to pay for it too :p
(passing up far more lucrative but irregular freelance)
only when you factor in the buying power on ebay did it make any sense whatsoever :p

and bigben2K thank you as well, your posts here where vary helpful ;)

Re: It begins
 

Are you doing testing for HardOCP?

Rattle FrgMstr's coiffers.

Re: It begins
 

Bill can correct me if I'm wrong. However, I believe the reason he's so "smart" is because of practice. He's made lots of mistakes already. Smart comes from learning from when you were stupid. Even better is when you can learn from someone else that already paid for the lessons.

Re: It begins
 

yup, experience is the accumulation of errors
but a point of semantics (wonderful stuff, almost as good as philosophy)

'smart', if we use the IQ version, relates directly to the rate at which info can be 'absorbed' from written text (well documented, don't argue)
- so I am very smart; YET yesterday, having the same source data as TM, I was unable to follow simple instructions
- so I do not break my arm patting myself on the back, plenty dumb with even simple instructions

smart in my book is learning from someone else's errors; here again I'm not too sharp,
I have to make the (obvious) errors myself to 'internalize' them [also just what children do to the dismay of parents, "experience does not transfer"]

re the subject at hand - testing, I have bought SO MUCH CRAP over the last 6 years it is incredible; inadequate, obsolete, unsuited, broken, whatever
- no free lessons, particularly for the self-tutored; now I know professionals in the field I can querry, so my errors are fewer and smaller in scope

so yes Brian, for us 'smart' kind of equates to experience + comprehension
for 'stupid' examples speak more loudly than words; consider politics and religions
- but note they both are stupid only for the masses, the leaders live quite well Thank You

Re: It begins
 

now thats dedication.
looking forward for your cal runs.

side note:

- the keithley DAQ cards have a larger latency than the NI's that can limit fast aquisition. a friend of mine picked that up while trying to make a control system for an inverted pendulum. not really that relevant as the rate required is not very high, but just a heads up. given the choice, go NI.

- the Fluke (damn that's ancient) is not loggable, however, you could "hack into it" and output the signal to the display. Or use a webcam and a visual aquisition :D.

Re: It begins
 

well the switch speed for the 2700\7708 is 3ms which is fine for the measurements Im looking at logging,
Ive actually got the scans set at 1 sec, and its internal memory buffer will do 55,000 readings
of course with the computer I can poll it and write to disk indefinately

on the control side I was going to use the NI PCI-DIO-96 ;)

I bought that Fluke before I knew what the hell I was doing, but its reasonably useful as its own "remote" unit

step 2
wire up and log multiple thermocouples

http://images.dr3vil.com/files/default/MultiTC.jpg

cant seem to get the ExcelLINX plugin working properly,
its hardcoded to GPIB1 or 2 and my DMM is on GPIB0 so I keep getting a configuration error
(the above is again the Keithley runtime only from the scanning side)
scale is C with a little lighter and water bath action

Time to wade into the IVI and VISA configuration documentation for configurations....again :p

Re: It begins
 

update: was canned by Kyle when I couldn't get repeatable results, at issue was having the thermocouples directly wired into the the DMM, making it impossible to swap out components on the case without seriously moving the sensors, also was doing "whole room" gradient heating putting all the equipment through the same stress testing.

been working on the test chamber, and rounding out the other test suites, just landed a DegreeC ATM-24 and this time the test chamber is up as well as having a sheilded and "pluggable" interface between the DMM and DUT.

I'll be "mapping" the "test case" (likely one of many platforms I'll eventually have,this one a Chenbro XspyderIII) for a proof of concept and to solicit other case and turnkey cooling solution reviews

now aligned with TechPowerUp and W1zzard

Re: It begins
 

Too bad ya'll couldn't work it out.

Let me know if you'd like to have your own forum on the WBTA, to present your testbench. Open or read-only, your choice. PM me for details.

Re: It begins
 

actually working with W1zzard has some distinct advantages ;)
we are currently working on putting together an underwriter program for the lab.
I have to round up the sponsors, but he sees the value of that.

I would like to post a worklog over there if you don't mind thanx ;)

Re: It begins
 

You're all set:
http://wbta.us/forums/index.php?board=37.0

Yeah, I need sponsors too. NordicHardware has no budget, and they're in Sweden...

Re: It begins
 

thanx ben I'll start with mirroring my TechPowerUp worklog ;)
