Here’s a cool DIY on making your own CO2 system.

Carbon is the fundamental element that all life on this planet is based. Plants are no exception. Since plants have no way of getting to their food sources, nutrients have to be obtained from their surrounding environment. Plants use many macro and micronutrients, carbon dioxide (CO₂) being one of the primary macronutrients. In an aquarium the limiting factors are most likely to be (in order): light, CO₂, micronutrients (trace elements), and macronutrients. Micro and macronutrients are usually supplied in adequate quantities by fish waste and the addition of fertilizers.

4. In a response to ridiculously long mattress names: “They confuse us with silly product names (the Sealy Posturepedic Crown Jewel Fletcher Ultra Plush Pillowtop or the Sealy Posturepedic Crown Jewel Brookmere Plush?). They flummox us with bogus science (”pocketed coils”? “Microtek foundations”? “Fiberlux”?). And they weigh us down with useless features (silk damask ticking?). It’s like buying a used car, and almost as expensive—I’ve seen mattresses going for $7,000. What’s a consumer to do?”
   Yes, this is true, let’s just buy some memory foam and forget the rest.

I have been struck with the zzzzz sickness lately. I can get to sleep at night and feel like my whole
world is falling into (or needs to) the zzzzz world. If I start working out more often, this should be
better… (this flu is killing me!?!) Regardless, you can read about psychology today’s article on
how to get a better night’s sleep when you can’t sleep.

The biggest sleep robber of all, however, is work—the puritan ethic gone haywire in an era of global markets. To accommodate the relentless pressure for productivity, we’re sleeping less and spending less time in social and leisure pursuits; the resulting stress can steal away even more sleep. Consider this: We’re not only missing more shut-eye, we’re having less sex, too.

P.S. I have to agree, the last part should be more on top of our priority.

Wow, check this color organ out, it almost looks like candy.

The circuit itself consists of an electret condensor microphone feeding a two stage preamplifier with a sensitivity control. The signal is then split up into three channels with individual level adjustments. Each channel has it’s own filter circuit, so that they each respond to a different range of sound frequencies, one each for treble, midrange, and bass sounds. The signal is then sent to an LED bargraph ladder circuit, with red/yellow, green/white, and blue/green leds for each channel respectively. Two LEDs were used for every one shown in the diagram, and the LED resistors were increased to 1K to extend battery life. With high output LEDs there is still lots of brightness even at lower currents, so this works well to lower current consumption. As well, there was a single purple colored UV LED included that is on whenever power is turned on.

Wow, I’ve always thought of this as pure magic but here’s the reasons behind the non-contact
heating appliances.

When an alternating electric current is passed through a coil, the coil creates a magnetic field. The magnetic lines of flux cut through the air around the coil. If a ferrous material, such a solid bar of iron is inserted into this coil, certain effects known as eddy currents are induced to flow in the metal bar. This causes localised heating, and ultimately heats up the metal bar.

In an induction heater, the coil is known as the ‘work coil’.
