thanks also, alex
heh - I just simulated a spindle using stepgen in velocity mode hooked into an encoder block. seems to work quite well.
the accelleration set by the stepgen makes it act like mass of the spindle
* skunkworks is sure there is an easier way ;)
skunkworks: whatcha doin?
I need to make a shift comp for shifting the Kearneys transmission
But I don't want to do it at the machine - so i need something that acts like the spindle
imaginary cordless drill?
you need a virtual shift comp?
skunkworks: I'm confused
to write the comp - I need something that 'acts' like the spindle so I can see if it is working correctly.
what SWPadnos said...
yah, what I said
right - I think I have it working though - for what I need. stepgen in velocity mode -> encoder. that way I get velocity and counts. (I plan on using counts to see how many rotations the spindle motor has turned - that is all I have for the initial gear shift)
toss in a small value sine (on the input) if you want ti simulate noise/speed oscillation
pcw_home: did you see this? http://www.electronicsam.com/images/KandT/conversion/servo/x-zservo_mount.jpg
Yes, quite a retrofit pulleys dont seem parallel though, cant quite see which motor ls connected to which output shaft
hmmm. actually, the noise should be added to the output
of the limit3
(yep or the hf noise would be filtered out)
Not sure what you would call a slew rate limited filter (its not linear)
pcw_home: the pullys where not in the correct position in that picture.
put pretty close
I wonder which of your product can be used as a replace of 5i20 on pci-less motherboard
Does it have PCIE?
but I don't know for sure (money decides)
If it has a one lane PCIE conn a 3X20 will do bu its expensive (we will have cheaper PCIE cards later this year)
The new 510 atoms have a mini-pcie connector If I get off my butt and make a cable adapter (minipcie -->cabled PCIE) those would be nice for cabled PCIE as well
skunkworks: I figured as much

Hey Guys, google docs has a new drawing feature. You can either publish or share and LIVE edit a drawing between multipli people, and save as PNG, JPG, SVG, or PDF
good evening from Germany

In respect to HVAC and duct work.... You have a floor register which is the pretty grill ting you cover the duct work that's roughly 4"x10", what's the thing called that it connects to?
One end is a 4x10 opening, the other end is 6 or 8" round
Hmmm, looks like it's called a "Stack Boot"
boot|sleep is now known as bootnecklad`
Isn't that whats used to melt the onto laser prints :-)
(melt the toner)
pcw_home: that would be "fuser"
This is what I was talking about http://www.homedepot.com/Building-Materials-Heating-Venting-Cooling-HVAC-Parts-Accessories/h_d1/N-5yc1vZ1xglZapt7/R-100209803/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053
comps are cool!
I think I have the initialization sequence working for the transmission

With a 110mm diameter x 100mm long iron casting, I wonder if having a core for the middle will actually cost a lot more than just making it solid and boring it out.
andypugh: your video is cool.
The eccentric turning one?
it turned out well
