Audacity saves the day

Sorry mate, I don't get that. Maybe I'm too old, or my sense of humour is limited.

Here's the real thing, recorded with audacity:
jlittle's typing session

Praise due to audacity, I've never tried to record audio before, but from ignorance to lousy recording took 5 minutes. and less lousy (had to change "from Built-in Audio Analogue Stereo" in PulseAudio Volume Control to "from Monitor of Built-in Audio Analogue Stereo") in 10 minutes. Google found tutorial recording computer playback on linux quickly. It was fun, things worked.

The song uses a lot of cow bell.

That's rather inconsiderate of them. They've a few versions on there though https://www.youtube.com/watch?v=FgOQtSOZP24

That's only the tip of their censorship iceberg.

True. In some ways it makes me sad that google owns youtube but in another way it has been a rather lengthy source of amusement to see such a massive company trying and continually failing to turn such an unordered mess into something sensible and profitable.

One of my favorite YT channels is "Cody'sLab". He just got his first "Strike" for a video on how to make gun powder from urine. That vid has been cited by the Science channel and a host of other big names but it apparently doesn't matter. There seem to be a herd of Snowflakes running around tagging any videos they don't like or don't understand.

I find myself unusual in that I like computers to communicate with me with sound, especially if I make a mistake typing and the computer knows it's wrong. In this case most computer sounds are far too long, I want a sound as quick as my fingers.

Audacity to the rescue, I cut a cowbell sound down to a tenth of a second, years ago now. Love it.

Because everything needs more cowbell...

Never mind youtube, he should be more careful with that sort of stuff in case it falls foul of some law. I heard one guy on a science channel was demonstrating what happens if you put dry ice in a sealed bottle. Result was an explosion. He got reported by a neighbour, annoyed at the banging and turns out he'd made a film of him committing an offence in his state for making an explosive device and got arrested. If I did that over here (UK), i'd risk having armed police kicking in my door and be on anti terror charges.

O good grief ,,,what scared little rabbits our society has become ,,,,,,,,,,,,,,we (us young teenagers ) used to make similar things with baking soda and lemon juice, you can do a week rocket with that...M80 confetti bombs (role it up in news paper with longer fuse attached ) and acetylene BOMBAS with milk jugs . wont tell how (one of us rolled up his paper fuse like a straw instead of tight and solid and it wint off as he lit it ,riped his cheek open from the corner of his mouth almost to his ear ) but it is ridiculously easy ...this was all under 15 years old.

16-20 we would play army in a gravel pit type area right behind the condo project we lived in in the Maryland suburbs of DC with M1 carbines and mini 14's ,,,,,if the ground got strafed next to ya you were considered dead ...wile the games were on you could hear it plain as day in the condo project and we would come home with them(the rifles) slung over our shoulders like it was nothing. late 1970's

Aaaaaa those were the day's

VINNY, about 1969 I was teaching physics and chemistry at a midwest college. The frat houses were tasked with removing a string of tree stumps so that construction work could begin on a new dorm. The 20 or so kids were using axes and shovels. Roots from the trees made shoveling nearly impossible and the dirt and small rocks in the dirt made chopping the roots nearly impossible. These trees had a diameter of about 1m. The biggest was about 1.5m. After a day of effort they had pulled one stump out of the ground.

I drove to a Construction company in Council Bluffs, IA, and purchased 50 lbs of 40% Ammonium Nitrate based dynamite and a dozen electric blasting caps. Cost about $35, IIRC, and I used my credit card to pay for it. No questions asked. I returned to the college campus and in about an hour blew ALL the old tree stumps out of the ground. Using a post hold digger I had the kids dig a single hole about 4" in diameter at a 45 degree angle to the center of the tree, underneath the roots. (Advantage roots do not have a tap root). Depending on the diameter of the tree I put 3 to 5 sticks in the bottom of the hole, wired up the fuse, and filled the hold with mud. From about 100m away I touched the wires from the dynamite across my car battery and each stump rose about 10 to 15' into the air and come down right next to the hole created by the explosion. The kids loaded the stumps onto pickup trucks and hauled them to the dump.

Each explosion was loud and around the 3rd stump a police car drove up. The officer got out of his car and sat on his hood. He watched one stump get removed and then got back into his car and drove away. Never heard a word from him. (It wasn't illegal do remove trees with explosives in town back then.)

It was no big thing, and nobody cared. Never heard a word from the college administration after I initially told them what the problem was and what I was planning to do to solve it. A year later a concrete form for the basement of the new library building broke and spilled a couple tons of concrete. The wall was good, but the hardened spillage was interfering with the placement of plumbing and wiring inputs. It took only about 450g of 90% Nitroglycerin based dynamite to shatter the spillage without harming the wall. What I had to be careful of in handling that dynamite was contact with the Nitroglycerin, which dilates arterial walls and causes rapid drops in blood pressure.

Ten years later, laws had been enacted preventing me from purchasing those explosives without a federal license. A farmer came in asking for help to remove some stumps on his farm. I took some KNO3 and sugar out to his farm, mixed them, stuffed the mixture into holes drilled into the stumps and stuffed them with the KNO3+Sugar mixture, packed the remaining hole with damp earth and lit the fuse. Worked like a charm.

Urine contains Urea, which oxidizes in air/water to form Nitrates. You can force it to mainly NaNO3 by using NaOH pellets to neutralize the Nitric acid formed by the oxidation. Those salts are water soluble and after filtering the solution through coffee filters one can let the solution evaporate. KNO3 is more soluble at 100C than NaNO3 and less soluble at 0C by a factor of 6, but if you use lye to force it then you can use the molecular weight to compute the weight ratio of NaNO3 reacting with C6H12O6 (sugar) to form Na2CO3, CO2, H2O and N2, by balancing that equation.

OK smartie pants ,,,,you win

ya nitrates can be fun ,,,,,,,,at that same condo project ,,I had a job helping out the maintenance department ,,,,,,,one winter we were spreading deicer on the sidewalks we had ran out of rock salt and started using fertilizer I was waring the standard brown cloth work gloves that were damp/wet and got saturated in the fertilizer ,,,,,wile on brake I was smoking a sig and it burned down to between my fingers ,,,the gloves started burning like a firecracker fuse and I puled them off real quick , kicked snow over them and stomped it down , to my surprise they kept burning and burned right through the snow .

ANFO anyone ? and of course Audacity to record the bang ,,,,,,,lol

Nice fuse, VINNY!
Easy to make, wasn’t it!
