Well, actually it's the Supreme Judicial Court, or SJC.
As a young ham, myself and another member of our club were rebuked for what we thought was a clever workaround to a persistent jammer. We came up with a list of repeaters, assigning a number to each. When a jammer would come along, we'd simply say "meet me on number 4" and we'd QSY to that repeater to continue our QSO.
At a subsequent meeting, one of the OM officers of our club told us to knock it off as it could run afoul of the "codes & ciphers" prohibiting of part 97.
In the old days, before computers went solid state, smoking on startup was often put down to worn valve-guides.
Damn... I think Americans call them "tubes" -- in which case the joke doesn't work
Because honestly no one in medicine cares. There's not just one single environmental source of Cryptococcus, pigeons for example are known carriers. Getting rid of these trees is not going to prevent Cryptococcus infections anytime soon. What will prevent them is getting the HIV in the infected properly treated on a combination antiviral regimen so their own immune system can prevent the infection in the first place.
Worst that can happen? Well, since this is basically a roll of the dice as to what happens?
Pain originates as nervous system signals. Wouldn't it be great to permanently switch the pain centers to on in these quadriplegics with no recovery of motor function? And someone else already brought up cancer.
Don't ask, "Well, how can it possibly get worse?" Because it can always get worse.
There is almost no difference between say a $250 helmet and a $1000 helmet other than the graphics.
Sure, the super-cheap $50-$80 helmets can be seriously lacking in safety but almost anything above that is fine if it fits your head and has the features you want (fit, noise, venting, etc).
Worth it? Meh, probably not.
I wonder how much it would cost to simply take a regular helmet and some Chinese electronics off eBay to make the same thing. I'm guessing significantly less even including your time to build it.
I mean you're looking at less than $100 in raw parts for GPS + Arduino + HD Camera + display controller/OSD. Not sure about the HUD part but I believe it's just a projection on a small piece of glass, probably also less than $100 in parts by itself not to mention alternative hardware implementations that might be cheaper. Add $300 for a decent helmet, wire it up and you're done.
Personally I think I would find the HUD hardware incredibly distracting. Not the HUD itself mind you, but the stalk that sticks up in front of your eye. I would rather it be projected on the visor even if that means it's not always available (eg. when the visor is up).
