Re: pic: Night & Day
I wonder what the difference is on the digital output of the dig. sidecar between the victor pwm VI and the jaguar pwm VI. If someone could check this with an o-scope that would be pretty cool.

Re: pic: Night & Day
I wonder if the Jaguar has to be calibrated like the victor. First thing we should test is if the 'neutral' of the Jaguar is truly 127. There's a 'calibrating a victor' thread around here somewhere and I won't have a chance to even ask our team to do it until Tuesday.

Re: pic: Night & Day
Calibrate, With it's mini-computer like size, it should calibrate and program itself. LOL

so, that means we wont have any delay?(it uses wifi to communicate with the OI right? so does this mean it will have a faster reponse then the victors?) |
Re: pic: Night & Day
Looks pretty cool. I can't wait to get to try them out with the new control system
|
Re: pic: Night & Day
The only downfall as stated earlier is its size compared to the victors. Now that you get an actual pic side by side, that has huge ramifications on the amount of additional space you need to run them.
At least they are CHEAPER for now...........:cool: |
Re: pic: Night & Day
The cheaper price will remain throughout the 2009 season according to Luminary Micro if you use the proper link. See post here for info: http://www.chiefdelphi.com/forums/sh...&postcount=102

Re: pic: Night & Day
I was thinking about it, the size isn't toooo bad. Life is fun of obstacles, finding a path around them is all the fun.
|
Re: pic: Night & Day
How much more does the Jaguar wiegh then the victor?
|
Re: pic: Night & Day
I have to say, I'm not too thrilled about having to pack these suckers into our robot... In the past, electronics have already been a squeeze. We shall see, though.
On the plus side, it seems like it will be slightly harder for us to drop shavings and chips onto the H bridge, and fry them! This is good, because high school students seem to have an impressive ability to fry any electronic system you put in front of them... |
Re: pic: Night & Day
Jaguars and Victos weigh approximately the same. I know from holding them and comparing; there is no noticable difference unless you put it on a very accurate scale.
|
Re: pic: Night & Day
I simply cannot get over the size difference. I'm really not a complainer, but having controls aspects adding more weight, and taking up more space, on the robot is not exactly something I am looking forward to. I guess we'll just need to not put as much mechanical stuff on inorder to make weight and size.
|
Re: pic: Night & Day
It depends on the limits this year. I'm sure they'll take the new system into consideration when making the rules this season.

I suppose they could add to the length though. |

Re: pic: Night & Day
Oh, my bad. I misread the post. I thought he meant weight limits.
Well, as stated above, plan on cleaning up your electronics nicely this year, and you should be fine. |

Wow, I guess he did. It's time for me to go to bed..... :rolleyes:

The size of the jaguar is a very real concern for us, regardless of how much better it's performance may or may not be. |

Re: pic: Night & Day
I imagine we'll see more 3-D layouts for electronics this year. The first layout we'll probably try is an upside-down "T", with the Jaguars on the vertical part.
|
Re: pic: Night & Day
I got our kit today, and i saw the pro and the con of the jaguar
Pro: good performance, SURPRISINGLY LIGHT WEIGHT!!! Con: looks even bigger in person (at least i think) |
Re: pic: Night & Day
Can someone actually weigh the two and post?
A .1lb difference may not be noticeable by holding them, but could easily be an entire pound on the robot. |
Re: pic: Night & Day
Yeah, I'd like to see some actual weights too.
|
Re: pic: Night & Day
If no one gets to this I can do it Wednesday.
|
Re: pic: Night & Day
Victor: 101.1 grams (.223 lbs)
Jaguar: 166.5 grams (.367 lbs) Ecck! :eek: (on the flip side the jaguar's do come with nice little stickers!) By the way, if anyone else wants to know the weight of anything I be glad to measure it. Edit: Updated with correct weights. |

IFI lists the Victors as .25 Lbs, even then, it's a good deal heavier. |

Re: pic: Night & Day
what about the weight of the old power distribution block, maxi fuse panel, and other fuse panel combined vs the weight of the new PD board

I too was struck by how much bigger they are in person than I was prepared for from the pictures. They're huge. |
Re: pic: Night & Day
Well, it seems that my scale was off, so I calibrated it (the wonders of analog technology). These weights are hopefully more accurate.
Victor: 101.1 grams (.223 lbs) Jaguar: 166.5 grams (.367 lbs) Sorry about that! |
Re: pic: Night & Day
150% larger,
150% heavier, lets just hope it performs more than 150% better =) |

at least i have had no problems with them. I would actually say that installation is a little easier since it is bigger, and they have also performed great so far! (u can probably spot the pro and con of that second sentence i wrote) |
Re: pic: Night & Day
I think burmeister forgot that area is the square of length. So the length is 150% larger... but the area, well....

Re: pic: Night & Day
Yesterday we figured out a nifty space-saving way to mount these, and I'll post a pic tomorrow night once I put the memory card back into my camera so it will save the picture :rolleyes:
Take a 1/16" wall angle aluminum piece that has 2.5" legs (hard to find I know, we had to cut metal meant for another purpose to get it), drill holes that are far enough up and apart so that a Jaguar can be vertically mounted to it. Then, mount the Jaguars back-to-back on the mount -- but -- rotate one of the Jaguars 180 degrees on the axis that's normal to the mount plate. This will put all of the motor outputs on one side and all of the power inputs on the other. Then, using either a 3" #8 bolt & nut, OR a #10 2" machine screw, you can screw the Jaguars to each other. For a production mount piece, you can mill out unnecessary metal from the middle and still maintain the rigidity. WARNING: A #10 machine bolt will thread the inside of the holes. We haven't done shock testing yet with this setup, so YMMV for longevity of the mount. Other than that, your power distribution block will need plenty of room on each side! This isn't room for wiring, no, it's room so that you can horizontally put a tiny screw driver in the slot in order to take a wire in or out. You can't do this from the top of the PDB, nor really effectively at an angle. The PDB was the single deciding factor in the majority of our preliminary electronics layout. Could someone point us to an effective tool that has a flat 90 degree tip, to alleviate that problem? |

Every time this thread pops up I get Cole Porter in my head.

Re: pic: Night & Day
When I saw pictures like this on CD I thought that they were going to be like GINOURMOUS, but they really are not that big, and they feel like there construction is of much better quality, like it is a "top of the line" type product. I actually like them, and don't really mind the size, because they pretty much are equal in weight.

I'm not too excited for these until we can use the CAN features, and see how the nifty built features actually work.

And, as stated somewhere in one of these threads, it's an awesome engineering challenge. Where's the fun if it were just a puzzle? ;)

Re: pic: Night & Day
Im going to touch on a few points here.....
