Thought 47: Fireworks Producing Notes

Well, it is almost the Forth of July and it is time to break out the old fireworks. For some this means going to a fireworks show with a local orchestra to play while the explosives go off in time with the music, or at least relatively close to it. Well, here's the new idea: Create sound wave chambers for the fireworks such that they produce their own notes. Then time the launches and explosives to create music in the sky. The sound would be produce similar to how a pipe organ works, only using the explosive forces of the firework to produce the expanding air. The rocket tube could serve as the resonating chamber for the explosive and produce and in air note. Now string together a bunch of these and you can play perfectly synchronized music/light show, all with crazy explosives and physics.

Anyway the test plan is to get some PVC pipes of varying length and throw fire crackers into them. I know it's a small test, but I am not exactly a pyrothechnitian, but I pretend I am once a year.

You're. Doing. WHAT?

At our HOUSE?

Oh, this can only end badly. I think you've been watching the redneck neighbor children blow up coffee cans while they stand on them.

Thought 28: Rise Above

Sometimes the world makes you feel helpless. You think you can change the world and the harder you push the more it pushes back. Sometimes it moves a little, sometimes the little bits add up and you find you CAN move mountains. You just have to keep your attitude high as that IS the thing you can change. No matter bad things look just keep the attitude up and things will begin to get better, slowly, but surely. Heads up, stay positive, we're all in this together!

Thought 49: Clone of Your Own

Skit: "A guide on how to clone oneself" [name] Here. Have you ever found yourself needing a second set of hands [examples of hard tasks], but the help just doesn't quite understand you. Well have I got the perfect solution, a clone. With a clone, for better or worse, at least you'll exactly what kind of help you've got. But, [name], I do not have a expensive bio-science lab with cloning tanks. Well then have I got the cheap home-grown-clone-kit for you, and I already know that it works, but more on that later. If you're like me, you come home filthy at the end the day and need a bath, which is where incidentally I do most of my best thinking. One day it struck me, one of those running down the street naked ideas, that I was wasting all of those skin cells and bits of hair at the bottom of the tub. If only there were some way I could utilize those cells to make a clone of myself. What I needed was an organic filter to capture all of that lovely biologi...

Thought 16 - Kid Power

In response "Thought 14 - Perpetual Cat" sugarbumkin said, "The same theory could be applied to balloons tied to kindergarteners at recess. I like it." Well this got me thinking... Clothes with that are laced with MEMS generators. A MEMS generator is a solid state electronic circuit that generates low level of current though passive motion of the environment. Things like temperature change, acceleration, and even Brownian motion are converted to power using a MEMS generator. So, now we have attached them to small free moving bipeds of pure energy. How do we get the energy back. I figure that we isolate the playground into a large battery configuration where the children are running around on a conductive plate that makes contact with the heels of their shoes. They will run around with a super capacitor in addition to the MEMS, when their feet touch the ground the super-cap is discharged into the conductive plate underneath them. I do not think that the childr...
