content: Hmm, I don't get this. Why drag (and potentially damage) a working scope on a charity run? What's the point of doing this?Why don't you do the mud run without the scope, sell the scope and donate that extra money from the scope to the cancer fund too?Or donate the scope to a school or similar where it helps educating kids in electronics?

content: I think it is a great opportunity to drag an oscilloscope with you, but not a bench scope. I think it would be great to take a portable field scope with you. Something like a Fluke 123 style scope. Could be a great testament to the possible durability of an instrument like that, and then with a follow up review and teardown of the scope.

(Yeah, I know that a large percentage of current Discovery's audience have no idea on how a oscilloscope looks like, let alone works)

content: Do you have a slingshot so you can shoot them 100 foot or so. Tie them together so the get roughly the same treatment. Rope with a rope to put them under water. Possibly a drag test.Teardown (just case removal) to see water penetration. Can you hear them before and after. I wonder how the mics will hold up.Should be fun anyway. Do take a non-waterproof one as well to see it die a horrible death.

content: Rigol have said they want to be involved, any suggestions on how?One idea is to simply donate gear and have a 99cent ebay auction, the proceeds of which go to the charity.Having a hard time thinking how Rigol gear could be used at the event apart from just dragging it through and destroying a scope or something for kicks.Problem now is I'm running out of time to get gear and decide on something...The angle is really mostly about the Discovery Channel now, but I'd also want a footage I can put on my channel as well that is at least interesting to the EEVblog audience?

content: - I think teardowns after the fact are suitable for the channel.- A scope is a pretty big thing to drag along but... If you had a hard waterproof case or not it could survive and be used to show what's needed. Of course the scope could be damaged but that's TV. Call it the Fedex / UPS crash test. Auction or give away the scope after, maybe even repair it.- A Rigol arm / headband and free stuff for the audience may be all that's needed for the on site crowd.

content: Quote from: Chris_PL on November 22, 2014, 12:19:41 pmThat's a possibility!Yes, I foolishly will be running in the clean room lab suit!I've had it all taken up from it's XXL size, so kinda fits me a bit better now.If the heat doesn't get me, the weight of the mud caked onto the suit might just do it.NEWS: The Discovery Channel have just said that they can't make it, some screwup with the Visas or some such.That actually makes it a lot easier logistically for me now, as I only have to worry about getting my own footage.But it's a bummer because that would have been fun, and my brother-in-law Phil was going to ride around in the 4WD with them recording them recording me. So that would have made for some nice behind the scenes shots.I'm still waiting for that rugged mobile phone to test, and have ordered a Kein Tools MM500 rugged meter to take around and I hope that gets here in time but I won't count on it.I was going to use a JVC waterproof camcorder on the run, but it went missing in the mail. Well, was signed for by someone who doesn't work for my storage unit company, and has since vanished.So all I'm left with is a cheap SJ4000 action cam to shoot this with because I have lost both of my GoPros.So it's all coming along nicely!

content: Bunny suit fan ventilation may help to ward off heat stroke. May I suggest a cheap computer type cooling fan and a battery belt. The battery belt is something I've often seen mobile video crews using to power their shoulder mount video cameras in the past. The fan could be tie wrapped to the belt and to one of the holes you cut in the suit. The holes other than the one for the fan could be small slits to let air in to be exhausted by the fan. I realize that the fan is likely to clog with mud eventually, but it may operate long enough to get you through this.
