I just want to clarify you that what you are looking at are Amps not Volts. Fuses only go by amps. The voltage will be displayed elsewhere on your Power Distribution block.

We're here to help you Tomy, not to criticize. :D

okay if you look at a power distribution bot we put it one that says 30A max and we firgured out that we put the poles backwards

In many dc devices, there is a diode placed across the power supply input, which is supposed to cause a short and blow a fuse if you reverse polarity. If you reversed polarity and had too high of a breaker, it may have just burned open the pcboard trace and possibly left the diode shorted as well. You may be able to remove or replace the diode, fix the trace, and be good as new.

i had my dad bring it to a guy that can make a computer for twigs and leaves. he said we blew a chip or something .... so that means we have to get a new one right?

Maybe not. Can you get any numbers off the component? Maybe take a picture of it? Depending on what the component is, you may be able to make a trip to radio shack, and with a little soldering iron work, fix it.

Per <R59> I think if it were repaired, it wouldn't be competition legal. In fact since it sounds like it's already been disassembled, it wouldn't be competition legal.

maybe i do not know but i was able to get the circuit board out and there are 2 chips on the front panel that look like they have yellow ink on them maybe that is the reason

Yes, it appears <R59> precludes it from being used for competition, but it would at least be able to be used for testing, and give the team time to acquire a replacement.

what do you mean we get a free one or what...?

Rule R59. Thanks for bringing this to my attention.

I agree with the rule of changing the configuration of the component, but simply opening the case forces you to buy new units to use in the competition? No. I do not agree with that.

We currently have an Analog breakout module with a blown 5V 3A regulator. Nothing against AndyMark, but they want $24.00 for a replacement. The faulty IC can be bought for $4.

If a local shop were to repair this module, then the part isn't legal in competition? No modifications were made to the circuitry.

An exception should be added to this rule. A team that declares a component was repaired, and has documentation that the circuitry wasn't altered from the original design should be allowed to compete with that component.

Again, I stress that opening the cRio, or one of those plug in modules is a terrible idea and is asking for trouble. These are too complex and should only be handled by NI. The same goes with the drivers station, the game adapter, the camera, Digital sidecars,and the Linksys router.

Everything else should be loosened a little to take into account for custom circuits. I may not want to use the analog breakout, but design my own interface with a 8 to 1 multiplexer on every input pin. This should be allowed. I have no intention of doing this, but just throwing it out as an example.

Re: Have you burned your reciver?
 
so with my team even if we fix it, we can not use it. and we have to spend $100 to get a new one?

Re: Have you burned your reciver?
 
Jim, you may want to pose your question to the Q&A. It may be legal to attach your custom circuit to the second 9201 modules - I do not know. It would be interesting though...

back to my problem do i get a free one or a cheep on or what...?

Not to sound rude, but... you did not follow the directions and hooked up your gaming adapter wrong and apparently wrecked it. Why would FIRST give you a free replacement for something that could have easily been avoided by simply following the directions they provided?

You can certainly ask on the official Q&A if you want, but I'm fairly certain they'll tell you to go buy a new one from Best Buy or somewhere else at full price. FIRST can't afford to give away spares to every team.

It no longer works. does anyone know how to fix it or where to get a cheap one?

In my country, if we burn some electronic equipment, you cannnot go to the regionals in Los Angeles, because we live so far from USA and we wait about 3 weeks to the package arrive here...
