And private property or not, the OP is most likely going to need an FAA waiver to launch such a large rocket (over 3.3 lbs total liftoff mass or more than 125 grams of propellant mass).
The best advice is to join NAR or Tripoli, find a local club and launch with them. The club does all the FAA paperwork, and can help you get certified to whatever level you want.
Analog plotters were at one time common items in engineering labs, as well as chemistry labs where they served as output devices for chromatographs, spectrometers, etc. HP pretty much owned the market, and they moved an overhead pen over a stationary sheet of paper, which was held down to the bed by an electrostatic charge. A typical unit shown here:
His next phase prototype should have a 10-20 HP IC engine (lawn tractor motor, etc.) for the prime mover, and the output shaft of his device needs to be connected to a dynamometer/load absorber of some type.
Can he still control it with the small DC permag gearmotor he appears to be using?
I was offered a job with a mid-level defense contractor when leaving school (mid 80s), but decided against it on moral grounds. I know a few others who made similar decisions, but unfortunately not enough of them...
Yes, but the Apollo/Saturn V center building was only completed in 1996. Prior to then, the rocket sat outside (near the VAB), and suffered severe damage from the salt air and weather exposure. The rocket was cosmetically restored prior to the opening of the new building.
Interesting. Do you need to extract the THC from the weed and put the extract into a filter cartridge (essentially making hash oil), or do you just stuff a bit of bud into the e-cig near the heating element? Does it taste like weed when you smoke it?
Sure, and when the investigation shows that nicotine is a toxic, addictive drug, the ALA will then claim that a total ban is justified.
This crusade against e-cigarettes reminds me of what happened to MADD. They started out with a laudable goal (reduce drunk driving fatalities), but once they largely ACHIEVED that goal, they shape-shifted into a neo-prohibitionist organization which seems to be working toward the criminalization of DRINKING, not drunk driving. Witness the calls for ever lower BAC limits, which could have some people "legally drunk" after a single beer.
I have to question that chart somewhat. It shows heroin to me much more physically harmful than amphetamines, which flies in the face of reality.
People can (and have) managed to remain addicted to opiates for many years at a stretch, with the only physical problem being chronic constipation. Witness all the doctors and nurses who use opiates for years with nobody suspecting a thing. Assuming pure drugs are available and clean injection practices are followed, a heroin habit doesn't necessarily lead to physical ruin. Addiction, yes, but physically this class of drugs isn't all that toxic.
OTOH, just about everyone who develops an addiction to amphetamines ends up destroying themselves in pretty short order. permanent neurological changes and deterioration of many organs are widely seen in amphetamine abusers.
Where did it come from, and what is it supposed to represent?
It's probably just cause I'm an electronics geek with a fondness for "hollow state", but that thing sure looks like the business end of a "magic eye tube" to me.
For those who have no idea what a magic eye tube is:
Something as simple as a dslr camera requires millions of dollars in testing to ensure that the device won't cause problems in vacuum or in zero g, etc. It even goes so far that NASA produces its own battery charger for the camera instead of using the commercial charger that ships with the model.
NASA would need to be sure that any lubricants used on the camera's moving parts (yes, even DSLR's have them) will not outgas if exposed to vacuum, or freeze/liquefy when exposed to the wide temperature variations experienced in space. The same would go for components like electrolytic capacitors, batteries, etc, which might rupture and release toxic chemicals when exposed to a vacuum.
The battery charger most likely needs to be customized in order to make one that can plug into the 28VDC or 400/800 Hz AC power systems typically used on spacecraft.
, due to it's illegal status. Smoking is the method of consumption that gives the user the maximum effect from the minimum amount of pot. This is important when dealing with an illegal commodity that costs hundreds of dollars per ounce.
If pot were legal, the costs would be more in line with what it is, a dried herb. This would allow users to ingest it in less efficient ways, such as putting it in food. Someone eating a brownie under your bedroom window isn't going to annoy you that much, is it?
Unfortunately, unlike adding poisons to alcohol products, there is no government regulation requiring the use of this stuff in antifreeze. Such use is completely voluntary, and since it costs a few cents more to add, most manufacturers don't bother.
They studied men who already HAD the disease, and allowed it to progress untreated to see what would happen.
Still completely unethical, and one of the more atrocious chapters in US medical history. But claiming that the patients were intentionally infected with syphilis by gov't docs is simply wrong, and gives ammunition to those who would deny that the whole thing ever happened.
OTOH, the government did intentionally inject people (including mentally retarded children) with radioactive isotopes to see what the effects of nuclear fallout would be.
Actually, we don't "poison" antifreeze with ethylene glycol. Ethylene glycol is used because it makes a good antifreeze.
Unadulterated ethanol would be perfectly usable for most industrial purposes. But the government mandates the addition of other toxic substances which serve no purpose other than making the ethanol unusable as an intoxicant. That is the key difference here.

This is just a bigger lens kludged onto an iPhone. Epic fail....
as the OP's assertion is pure bullshit.
As is the one about psilocybe mushrooms being toxic...
Actually, he was forced to move his work out to the NM desert because of opposition from his neighbors in MA.

It seems to me a magazine publishing such an article would be exposing itself to significant damages.
In the particular case of QST magazine, it would also piss off their single biggest advertiser, Icom.

I agree.

You could drive it with a small DC motor with an electronic speed control, as shown in the prototype.

In that it is non-addictive, and just about impossible to die from an overdose of, yes.
And Armstrong and Aldrin didn't land until the 20th, either...
Was I the only one here who saw those in the headline, and was expecting a bunch of Viagra jokes?

Sold under the trade name "Bitrex". Just a tiny amount of this stuff makes the antifreeze so bitter that kids and animals won't drink it.

Care to share the structural formula for that one, before you head out to claim your Nobel in chemistry?
