Legality of older spikes
My team has a bunch of 554's donated old spikes sitting. I also am wiring a light panel (red, white, and blue LEDs in the respective shapes) using 3 spikes.
These spikes must be old... they are smaller than the ones they make now (not by much), and my knowedge from my previous team tells me that they are older than 06. they are a better fit for the wiring board we are using... and i think they look cool! they are true spikes though... my questions: 1. are they legal or must I use the newer, larger spikes? 2. do they behave like newer spikes (in code, spec. labview)? |

If they are available COTS for any team to purchase from a VENDOR, they are legal. If they are not, then they are not. |
Re: Legality of older spikes
someone of better experience should answer this for you but i think they would be legal.. but the programming may not be the same. I'd also be in fear of burning more fuses.
best of luck in the long run 2057 <edit> the spikes would only be legal if they came in a past kit of parts i believe. look at the rules :) </edit> |
Re: Legality of older spikes
There were two types of the older spikes. If I remember right, here's how the old ones worked.
Spike kind #1. (I think these were blue) When off, both M+ and M- are tied to ground. ![]() Spike kind #2. (I think these were red) When off, both M+ and M- are tied to 12V. No picture of those... You can tell they're the old kind because they have no sleeve for the PWM cable to go in. You can imagine how much of a headache this was for teams. I remember we glued ours in place. The current generation of Spikes are still blue, unlike their Victor counterparts. ![]() Someone may correct me. I'm going off of my memory. Speaking of old Victors... we're using the old red labeled 884 Victors this year because our electrical guy likes the sound of the fans more. But as far as Spikes go... the blue ones are still legal. Red ones are not. |
Re: Legality of older spikes
Team#2057-Vegas, you are mistaken. Whether or not something was in "old kit" has no bearing whatsoever on its legality now.

Re: Legality of older spikes
yup. the first one is it. we have like 4 or so... off being tied to ground is actually a good thing for what i am doing with it...
and they are legal? if so, then very cool! i like the retro look! the no shroud issue i will deal with if it becomes a problem. they also gave us a whole IFI control system... one of the victors is the old kind with the shiny red foil text; the rest are blue like the newer non-vex ones. but they all are 884, not the ancient 883's . it is mounted on a IFI kit chassis. but the mechanum wheels are AM and the controller is custom hand soldered... It was very nice of them... it is very fun to drive around... |

Re: Legality of older spikes
There is not a distinction between the old style Spike and the newer style Spike except as described above. Likewise there is no real difference between the Red Label and Blue Label Victor 884. (There was some confusion during the transition of the labels.) However, if one reads through the manual you will find no mention of a requirement to use only Victor 884 or jaguar speed controllers this year. The rules have been relaxed for the use of any controller as long as the command is generated within the cRIO where it can be controlled by FMS.

Re: Legality of older spikes
Doesn't <R48> come into play here?

I would highly recommend following the blue box instructions to get this old style Spike approved as a power regulating device for this year before basing your design on it. |

Re: Legality of older spikes
I will do that.
WAIT- I am using them for a LIGHT. team update #8 allows using spikes OR any other relay for Lights. does that mean that for my intentended use, this thread is a moot point? |
Re: Legality of older spikes
In response to TU #6, I am not so sure. Please standby.

Re: Legality of older spikes
re-reading the update, i see that it refers back to the relays allowed, being spikes.
IIRC, the only difference between the old blues and new spikes is the plastic. they seem to have the same "guts" |
