Oh, wow, I am blind. Totally will add to classifieds. Thanks m8.

Hi guys, doing a big cleanout. Found a box of myco gear that could use a new home. includes a hawkins 5L heavybase PC (worth ~$60) in good working order, only used a number of times, some clamp-lid containers for cakes, and a thermostatted digital heating controller for incubation using a box-in-box design. Also contains some sterile syringes and needles. Pickup 4157/QLD, or happy to get a quote on shipping. Offers by PM please. Cheers, S. PS: Mods please feel free to move thread as appropriate, I haven't been here in many years, could not find a myco trade forum, just seed/plant exchange. Im happy for the thread to go there if its more relevant though.

ahem. flying spaghetti monster. and dont any of you lie, we can all agree on that.

flying spaghetti monster.... ..just saying.

I think so, potentially. However the amount of mass gained by increase in energy is so small that mere convective forces would probably dominate.

I think what is happening is that both mass and energy are conserved, but both general and special relativity indicate that mass and energy are interchangable via Einsteins equation. Consider this, for a chemical reaction to take place, some element/molecule must change energy state, otherwise no reaction would take place. This difference in energy can be observed, and also calculated. The difference in energy can also be computed as a function of mass via E=mc^2. I'm not sure what you mean by "sharing electrons retains their energy level", because I would tend to think that depending on what type of bond, and the associated nuclei involved that the bond would contain different energy. Consider a single bond to a double or triple bond. The sigma bonds have a different energy level to pi bonds. It is entirely possible to promote sigma electrons to a pi electron state and vice versa, which change their energy level. Regarding nuclei, a famous quote: So it appears that while mass and energy are conserved, they are only conserved when considering both. Also, hot stuff rises because of a decrease in density, but it's important to consider that density is just mass per space. A decrease in density doesnt make something have less mass. According to E=mc^2, the increase in kinetic energy can be considered as mass. So while the object's density decreases, the object's mass increases.

Do you study physics as a profession? I do appreciate the smack upside the head - sloppiness is not something that should be tolerated under scientific rigor!

I totally agree - perhaps i miscommunicated. As you say, energy, nor mass, is created, nor destroyed, merely converted, to which I totally agree with. I define over-unity as a practical element, not a thermodynamic one, ie, systems upon which sustaining the conversion of one type of energy or form (be it mass to energy or vice versa) is fully sustainable by the system itself. It would be a direct violation of fundamental thermodynamic laws to suggest the concept of overunity in a thermodynamic respect, so yes, it's a loose/practical definition. That said, in the end, regarding this topic, we are concerned about praticality, no? Also I was just about to prepare a typical noodle-800-page-defense to some of your statements, also the hot stuff weighs less than cold stuff, but you know, i'm totally okay with being proven wrong (rather, to be educated), and, you just did. Awesome, thanks. Perhaps I can use this as a defense as to why my yeilds in the lab are so low Just pointing out i did say that perpetual systems bear little significant use (if obtainable) - implying that they, currently, may or may not be obtainable. They're interesting as a theorem, but currently appear impractical, and perhaps currently "impossible" other then on paper (it is easy to define a closed system with no losses, but in reality this is not achievable with our current understanding of physics or engineering) Man, haven't been on this forum in many many years, come back and learn something pretty rad. maybe I should frequent more often.

Just putting a few definitions out there... May seem obvious but a lot of people get tricked up. Perpetual motion is merely 100% kinetic energy in a system recycled throughout the system. It bears little significant use (if obtainable) as it can only effectively store the same amount of energy put into the system. So it is pretty much limited to a battery. Once the energy has been removed from the system, it will cease to operate. Perpetual anything pretty much relies on the same concept. Neither of the above, according to current physics understanding, can exist. The simplest perpetual system would be thermal energy trapped within a container that possessed insulation that worked infinitely well, such that no energy was able to be lost. However, this is fundamentally different to systems which have an energy input, but the energy obtained is greater than the initial energy put in. These are 'overunity' based systems. Overunity systems are real. For instance, fossil fuel. Less energy is required to pump fossil fuels into a combustion system and ignite it than is seen at the output, which is why your car continues to run and supplies excess energy. These systems do not 'run forever', they merely have a source of energy of which is able to be accessed with less energy than the sum of the energy in the system.

Hi, selling some glassware: 1x 500ml erlenmeyer, ground glass joint and drip sheild (offers $10+) 1x 1000ml flatbottom flask, B24 ground glass joint (offer $30+) 1x B24/B19 400mm leibig condensor/stillhead combo, with silicone/glass (offer $40+) 3x 1000ml boiling flasks (no ground glass joints) (offer $10+ each) all as good as new. none have been used for anything illegal, or even remotely dodgy. In fact, the only thing that's actually ever been used is the condensor, and that was used for water distillation, like once or something. The rest of the time this stuff has been sitting on a shelf. I have no desire for it. prices not including postage. Private message offers please.. cheers

a ) My sent items folder is permanently empty b ) I generally receieve duplicate emails saying "xyz has sent you a new personal message", sometimes 3.

Unless someone changed the settings, as far as i know sent items were always saved... though i havent been on here in a long time. possible it's been changed. generally = the last 15 messages or so. didn't do it before that. might be the other person's machine but if they sent it twice i'd expect two messages in my inbox. i dont get this, just one message from them, and two from the shaman australis bot.

requesting a check on these weird dudes i found outside. Leucocoprinus birnbaumii ??

Hi there, I'm looking for someone with a playstation 2 with a modchip. Im looking for a quick job to be done, involving mailing a CD-R with a homebrew app on it and a memory card. All that needs to be done is to boot the PS2 with the memory card supplied and it will install some software to the memory card - nothing will be done to your PS2! Then just mail back.. If anyone could manage this, please let me know, i'd cover postage both ways + gift/money

Chemoffice costs a lot of money for a reason. while i have sympathy for those who cannot afford it, this is still blatently illegal, people can get it on torrents if they need to, but SAB is not a warez site dude.

the human eye is so weird and tricky.. you can really do a lot of sneaky things with it.

my values were using std 5mm led arrays. they are actually a LOT less efficient than the 1W luxeon leds and such. in fact my numbers show an extra 17% light using 1 watters. lumen output doesnt have a wavelength, but since plants only need blue and red generally, i did it against my blue leds @ 6000mcd or so. realistically the integral area of intensity*wavelength is removed with led's narrow range - one more reason they are efficent - no intensity is wasted on the green band for instance. you could calculate % of light wasted in green range on HPS and it'd be a fair bit.

actually i did them anyways out of curiosity. using factory direct leds, for standard 5mm leds, 1W and 10W leds, leds dont even come close. and when they do, it requires about 1200 watts to emulate a 430w son-t-agro... stick with proper hydro gear. it'll still be a lil while yet before leds can do it. ill redo some numbers comparing the periceved lumens to the plant given HPS distance to led distance but i have a feeling it still wont be that good. edit: wow, the power of the inverse square law! okay, i can compete with a son-t-agro 430w (500w rough power) for a 3x3foot domain with 300W power draw. amazingly, leds win. (wow just got it down to 256W).. I'm about to get into TC so i want in indoor grow area, so i'll build one soon and if it's good, i'll fabricate some LED PCBs and power supplies to sell to members in this forum if they want. (i have the facilities to produce these led arrays).. those ones going on ebay seem okay but are a bit of a ripoff, and have no PWM function for dimming..

that's cool tst.. to confuse us more, we must also take into consideration that the point source of a HPS/MH is totally different to an LED. LEDs ratings are in mcd, millicandela to candela. It cannot convert properly to the HPS/MH rated measurements of lux (lumen per m^2 @ 1m, useful for surfaces) or lumen itself, which is a rating of useful light which. Leds are sold wilth millicandela ratings which is a measure of intensity, and to get to lumens or lux you need to take into account the 3 dimensional angle/profile that the led emits. The unit is called the stearadian, and is, as it says, a stereoradian, an angle in 3dimensions, and generally looks like a cone unless you have a really strange lens on the LEDs. As the intenssity is spead over this cone-shaped profile, intensity is distributed leading to a lower luminous insensity expected (since lumens are candela per stearadian). From lumens you then move to luminous area, (lux) for a useful representation. If anyone is interested, i -may- do the sums for a theoretical led array to of a given size to compare to hps..

looking for spore print to id with, able to pay $$. if you have many types i may be willing to trade a brand new set of 0.001 (yes 1mg) balances for a fair bit. message me with species and cost please ps. i have 0.001mg balances still for sale, enquire by pm.

using leds in an array requires some calculation, unless you are buying modules, in which case, read the manual. 12v cellphone adaptor would be okay, given you are allowed by your system to input 12v, and the current was enough to sustain the led's total consumption. white leds arent used because plants pretty much only use blue and red (into orange) spectra usefully, so you're wasting light. the current problem with leds is intensity. leds are less intense than a HPS or MH. i did some theory for hydroponics peoples on replacing a 400w son-t-agro system (1m^2 plant area) with a standard ballast (draws into the 500w range) with leds, and the wattage was about 100w less but the amount of luminous intensity was significantly lower. plus the cost was much much greater. that said leds last a lot longer and are cooler so you can get them closer to plants. imho after lots of looking into this, leds arent ready..........yet.....soon..

Unfortunately they dissapeared - without a trace, oddly enough. That said it was a whle after the photos were taken next time i will snap up some open shots.

So like, just as I walked out of my last uni exam this little bird chirped in my ear and somehow I was able to understand what the bird was saying, and he said: "There's a Brisbane EB meet soon!" Anyone wanna shed some new light on this?

the mouth is designed to break stuff down, which is why anything you put in there generally degrades pretty fast. i believe the test targets residue of a particular oral "unprotected route" such as smoking meth/weed, smoking mdma or aqueous mdma. I'd really like to see what happens if a "clean" person (test negative) had 3 mdma pills and a marinol tablet rectally, and see if that showed up on thier tongue. alternatively i could swab your tongue for the usefulness of your last post

unless the officer cuts your tongue and samples blood into the test i can't see how this affects anyone who digests things in capsules or swallows whole pills. I mean, this is really an attack at smoking as a route of consumption. Bombing pills whole (not suggested) or recapping in vitamin caps would prevent any of the drug from being found on the tongue. Also, weed could be activated by boiling in alcohol and put in caps as an extract too. I mean, it's all good unless you get the stuff on your tongue right? Let them waste thier money testing our tongues..
