Isn't it a part of a microwave. We had things that looked very similar in room last year (like 10?) and they told me it was part of a microwave.

Yeah, that's a magnetron.
His new robot won't just retrieve your food, it will heat it up on the way.

Looks like a microwave magnetron.

*edit* oops someone he beat me to it *edit*

She's absolutely right. It's a magnetron.

So, what do you need that for?

A microwave works by exciting the h20 particles in the food creating heat.... so soldering is out.....thats why you cant heat a potato chip in the mircowave

Microwaves also excite silicon carbide, thats how microwave crucibles work. A portable metal casting robot?

A death-ray?

Re: pic: Secret part of my newest vexbot
 
Microwaves are built so that the magnetrons will not turn on with the door open, because the radiation is harmful to humans.

That being said, I'm going with Cody's death ray guess. ;)

Not enough H2O in the air :(

There still should be enough water in the battery soln. to cook the robots... ;)

Actually, we've been using microwaves for line-of-sight radio relay communications for quite some time now. Any time you see a radio tower that looks like the picture below, it's actually a microwave radio relay tower. Usually they are painted red and white.

(Actually, it was a technician who was servicing a magnetron that noticed that microwaves "cook" things, as his peanut candy bar became the first microwaved food. :yikes: )



So here's the question: is Tytus developing the world's first Vex space satellite? :eek:

First, I gotta try that. :) Second, if microwaves excite H20 then why the reaction with metal?

It seems like any bot safely using a magnetron would be rather large for a vex bot. Unless it's not made to move, but make you're existing microwave more awesome.

metals reflect microwave and raido waves a microwave oven produces a frequincy of 2.45GHZ the wavelegnth is between 12cm and 13cm. thats why your microwave oven at home has a perforated peice of metal in its window. becasue microwaves can't pass through it.

Re: pic: Secret part of my newest vexbot
 
You realize that this will omnidirectionally broadcast high power microwaves, right?

:ahh: i hope you wear your lead apron around this thing. along with anyone else in a 50' radius.

by the way, how on earth are you going to power this? they usually take 700~1500w input. (Thats 75~125 amps at 12VDC :yikes: )

just my 2 cents, but, i think this might be a baaaad idea....

This will be interesting to watch - over the internet.

Maybe he'll just use it as ballast.

Maybe it's supposed to be puzzling, like my laser. (Maybe I'll use that on a robot...)

Newest Vex bot? Oh... My. No Tytus, I do not believe this abides by the "Mostly Vex" rule you were asking about in the 1902 Vex Competition thread. However, I do believe your robot would damage the field elements pretty well.

We're talking about Tytus here. He has a history of not good ideas and bad outcomes.

Burn
A Tad Over The Speed Limit
Waterjet 1
Waterjet 2
Waterjet 3

And there you go. Have I proven my point? There was one more where he got branded on his arm but I didn't have time to get it.

no this has nothing to do with 1902's vex competition. i know better than to beam microwaves at a bunch of kids and sterilize the future of first.

Well actually... it could be. But I don't think so. I just had this information bottled up in this empty brain of mine and was looking for a place to use it. I told one of my coworkers about his experience with the waterjet when we were looking through a magazine and saw an ad for a waterjet.

I have a lot of useless information that is just waiting to be used.

I Saw this on Engadget today, looks remarkibly similar, and really really, sounds like something Tytus would put on a Vex bot, Researchers create Microwave Drill/Deathray

mabye later, not this time. here's a hint. It has to do with mobility

Steam engine? Seems a little inefficient, if that's what you're doing, but boy it would be cool.

not even close. the microwaves are not used for heating.

Not Likely unless it's used for an outside vehicle. Reason: The reciever of a RADAR must be turned off during transmit (except a noise radar). If it is not then the receiver will be burned out by the transmitted pulse. The 'on-time' for the reciever is long enough that the pulse would already be past it in the confines of an indoor arena.

I, too, am interested in what he is using it for. The magnetron cavity is tuned to a specific frequency (in the case of a microwave ovens magnetron..its the natural frequency of water). So for him to not use it for heating is....interesting, And probably means that that magnetron was never intended for a microwave oven.

Tytus Gerrish 25-08-2006 11:49

Re: pic: Secret part of my newest vexbot
 
it is tuned to 2.45GHZ just like a microwave oven. however supplying different voltages to some magnetrons can produce diffrent frequinces

OW! :ahh:

i think he needs to go back to chip sweeper status in the machine shop ;)


i have done stupid stuff too, gotten cut on and endmill, ripped my thumbnail with a tuning-fork-looking skate wheel folder, ....

but watch yourself around hot stuff :)

Re: pic: Secret part of my newest vexbot
 
Before we get too crazy here, the microwave used for communication is a relatively low power device connected to some high gain, directional antennas. Most are not harmful unless you choose to climb the tower and stand in front of it. Radar installations create more power than these in the picture. For those of you who are RF inclined, the brass cylinder sticking out the top of the magnetron is actually a 1/4 wave antenna used to couple energy into the cavity of the microwave.

Please Tytus, tell me you were careful when you extracted the device from an oven. There is some really high voltage capacitors that can hold a charge for quite a while that are connected to the magnetron.
