It's rating would be 10 watts. 100 amps X .1 volts drop.

Lefty

And another joke ruined by proper labeling, darn.

A 0.001 ohm resistor.



1/4w or 1/2w?

Finally got everything dusted off and started testing. No idea what i'm going to do with it yet. Will probably make an arduino environmental monitor for it. The little 8+1 port switch is just for testing purposes, I need to rewire all the jacks into that room before I move my 24 port gigabit switch in there. The orange on the top is about 300 feet of fiber optic cable, with six media converters.

Just saw this on HardForum:

Woo, progress!

Also, target shooting, hunting poorly, competition shooting, and fun.

Could you get a humidifier instead? Then you could just use the arduino to turn it on and off.

It's not like you can't use that up and get more.

Wizdum, when's coyote season?  What's legal for coyotes in Maine? Night vision? Claymores?


I'm not sure on that, Coyotes only became a problem recently. I believe any kind of shooting is illegal at night, for safety reasons (basic firearm safety, if you can't see whats behind your target, you don't shoot). You are allowed to shoot "nuisance animals" anywhere on your property though. If you just want to shoot targets you have to be 300' from other people's houses, unless they give you permission.

Also, there are restrictions on the "recreational use" of explosives. You can't do anything that violates noise or environmental regulations (no blowing up trucks unless all the fluids have been drained). Homemade claymores may be classified as an "explosive device" which is different from the recreational use of explosives. Real claymores are not legal in the US.

This is what bothers me most about firearm and explosive regulations in the US, they are so convoluted its very easy to do something illegal by accident. You can buy a hunting rifle, put an adjustable stock, heat-shield with quad rail, and new pistol grip on it legally, but if you then put a $10 plastic vertical fore-grip on it, it becomes an illegal weapon. Commercial fireworks were also banned here for about 20 years, but black powder was still legal. Kids just made their own fireworks instead, resulting in more injuries.

A well-regulated militia is by definition not a state sponsored army.
By who's definition?
Not your finest legal minds, it seems, who consider them an irrelevance, or an inconvenient truth.
The guys in Somalia on the backs of Toyota technicals, with NSVs, they're well-regulated, right?

Quote
It is not the right of the militia to bear arms, it is the right of the people.
But you need a well-regulated militia to maintain a free state?
That's what the amendment says.
If they have no right to bear arms, what do you give them?
Loofahs?

Somali mercenaries are in fact a well-regulated militia.

I did not say that the militia did not have the right to bear arms. The second amendment gives the people the right to bear arms. The militia is made up of the people, so they still have the right to bear arms. There are many well-regulated militias in the US if you know where to look.



I've followed this thread on-and-off but it is quite distasteful to me because this is such a great community and the divisiveness, especially on off-topic subjects is detrimental. I have hesitated to comment up until now; this will be the first and last. AFAIC, everyone is entitled to their opinions, and that includes the hoplophobes. This thread serves no purpose, no minds will be changed.

I just hope that we don't have to keep threads about Nerf off the forum and website.

I don't know, I'm kind of impressed at the civility in this thread. Usually people are cursing at me and calling me a baby killer by now.

That's just sophistry: Clearly, the "well-regulated militia" and the "free state" are meant to be seen as Good Thingstm - the colonists had not just spent two years fighting the well-regulated militia of a free state; in their eyes, they had just fought the brutal armies of a tyrannical oppressor.

Depending on who you ask, it is any able-bodied citizen, so 75%?
75% are reservists? That's impressive.

A well-regulated militia is by definition not a state sponsored army. Its purpose is to protect the people in the event that a tyrannical government attempts to use its military on the people.

The well regulated militia is separate from a citizen's second amendment rights anyway. It is not the right of the militia to bear arms, it is the right of the people.

What percentage of US arms bearers actually are members of a well-regulated militia?

Depending on who you ask, it is any able-bodied citizen, so 75%?

I'm a fan of the Penn and Teller interpretation anyway:

Would you be able to use something like an ultrasonic sensor? I'm not sure if it will give you an accurate reading bouncing off water.

or any other way i can overcome the problem?

Perhaps a new router? I've got an inexpensive Netgear 614 that works great. There have been previous similar discussions concerning internet connection loss. If you search the forum for ping and similar terms you might find them.

I agree. Something like the Ubiquiti Edgerouter Lite is a nice solid router (though probably overkill for a home environment). I have also heard good things about certain Asus routers.

If you keep pinging random servers, they may end up blocking you. Using something like NTP might work, or going to a basic website like google.com and checking the first line of the page for "<!doctype html>"

I don't think the misfortune of 100 or so people
Can we just get a level here?
You're equating the slaughter of children and the effects on their families and community with, say, not winning a lottery, or losing a bunch of keys?
A "misfortune"?
Wow. Callous just got a whole new meaning.

I was simply using the same terms the person I quoted was using. Sandy Hook was a tragedy, yes, but they were hardly the only children to die that day. People were murdered all over the world at the exact same time, no one is saying what we should do about that.

Do you need a BATF license of some kind to get black powder? 

Nope. Anyone can buy it. In Maine, we can set off up to 40lbs of it at once "for recreational purposes". If the police see us, they may ask if they can stay and watch, thats about it.

You can't walk down the street without getting your image transmitted somewhere at least a few times (per minute?). I wouldn't think many should take issue with transmitting a numerical approximation of a thumbprint. 

I think a good argument could be made that if someone wanted to keep their fingerprints "personal", then they would make an effort to not leave them everywhere they go...on everything they touch.  smiley-roll

I agree with you, but a lot of people don't:

No way to zoom in, good suggestion though. I am not on a tight budget for this project $200 is not a problem for this one. The conditions are clean, no need for error corrections or anything like that.

I'm thinking you might need to add a few more zeros to that for this level of accuracy. Quite a few materials expand more than 0.01mm when the temperature changes.
