anybody want a 5i22 at the qty. 5 price? ($342 vs $429)
or a 7i37T? ($65 vs. $79)
I need whatever it takes to get +-10 and encoders+io
the 7i37T is a screw-terminal version of the 16 input+8 output card
hte 7i33 is the encoder + analog servo interface ($69)
I'll take 'em if that helps your order
I don't think I need more units to get the discount - just figured I'd offer the discount to anyone who wants it
I think I'll be ordering for my customer, but I don't know for sure yet
ah ok, for the $10 it's not worth the trouble to go through you and have you reship
(qty 4 is about the same as qty 5, and they want 4, so I'll get one for myself :) )
I think shipping to you should be around $4 or $5 fora couple of small interface boards, and it's no trouble to do it
cradek: did you get anything but a 5i20 last time? I have one of the isolated I/O boards (ribbon cable, not screw terminals, on the output side) if that helps you
no charge for the inbound
I got the H bridge + encoder thing
hmmm. I have you down for the H-bridge and the isolated digital I/O card
not the servo interface
hmm I guess I got the isolated digital thingy
maybe I ought to wait to buy stuff. I should check out the existing wiring (once I get the docs) and plan a bit
cradek: I think you want the 7i33
the discount is much more significant on the 1.5M-gate FPGA card with 96 I/Os :)
analog servo interface
yeah - the 7i33 is going to be needed no matter what
I wish it had screws
yeah - that would be a very good thing
unfortunately, he's only got terminal versions of the 7i37 and the 7I42 - the two digital I/O cards
yay - looks like I'll be ordering the Mesa stuff
I love freebies
SWPadnos: the parport cards aren't available yet, are they?
I'll ask when I call
incidentally, Peter W sent me some SPI code, I'll be making a HAL/FPGA component with that for the A/D and D/A card I'm designing
I think it'll end up with 6 inputs and 8 outputs, all 16-bit, with a max update rate in the couple hundred KHz area
no takers on the 5i22 or 7i37T?
100kHz is probably faster than you can read it out with HAL anyway
guess not me
ok. order in, though I can probably add items for a little while (in case jmkasunich__ is watching ...)
the 7i43 is not ready yet - they only have prototypes
the 7i37T is sort of ready - they had a batch that got over-cooked or something, so they're a little warped
do you have a link for either of them?
err - www.mesanet.com , select parallel I/O - Misc I/O
the 7i43 is the first item, the 7i37T is listed along with the 7i37 - it's the same electrically, it just has screw terminal instead of the 50-pin ribbon cable for the outputs
is it the same price for the screw terminals?
nope - a bit more
the 7i37T is on the price list page
god - I suck at the internet
ok - I see - 10 dollars more.
yes, for a few dollars more
wow - that is a really good price compared to the pluto for what you get.
I think it totals a fistful of dollars
not that I can do anything with it until someone writes the firmware
well, it's mostly written. the VHDL and verilog code for the mesa and pluto FPGAs can be "recompiled" for the new device
the "only" thing that needs to be done is to recosntruct the pin constraints file for the new FPGA
(I put only in quotes just because even though this sounds trivial, it may not be)
SWPadnos: I want one of your analog boards when it's done :P
I'm not sure what the final cost will be yet. even without prototype PCBs and assembly, the components will probably be in the $150 range
I was probably joking :)
haven't unpacked the mesa yet.. not sure what I'll do with it :P
the :P clued me in a little :)
* alex_joni drools over ST31000640NS
looks pretty similar to the Hitachi 7k1000
they have the regular Barracuda 7200.11
but this is a Barracuda ES.2
anyways.. off to bed now
good night all
so - I got the stepper card to where it was befor it smoked. It seems as if one or more of the coils is energized all the time.

yep - 16 volts all the time on 2 of the windings.
the z axis was also fixed once before - very poor job
it actually is the l298/297 combo. so the current limiting should be working
hmm 2v on the ref for the z axis - .6v for the other 2 axis.
