Frogs Forever?

Here's a neat video of bullfrogs clumsily catching prey in gorgeous slow-mo from the Vancouver Aquarium. They point out that amphibians are potentially facing a mass extinction, due to wetland reduction and chemical contamination. (Check out the crazy gender-bending effects of herbicides!)

Trapping water frogs

Hi my name is Werner I am from South Africa, and a very enthusiastic angler (freshwater). I wonder if anyone can assist me with regard to a cheap and simple way to  make  my own  frog trap to trap water frogs, as I use these frogs for bait when targeting catfish. Any ideas and assistance will be appreciated.

frog fingers/gloves?

Hi! i'm working on a frog costume among several animals for halloween, and the frog hands have me stuck. The plans are for a red eyed tree frog, so it needs 4 long digits, with slightly larger tips for the distal pads/suckers, and only a small amount of web between the digits. I don't think it will be a problem to settle for 5 fingers, I'm more concerned with length, shape, and the maybe the webbing. Any suggestions or ideas are appreciated. Thanks, David

What type of frog is this??? Is it poisonous? Answered

I found this frog in the garden and i was wondering what type of frog it is. (it might be a mutant from our pond cos it is really pouted and it has probably mutated the frog) I also want to know if it is poisonous. I think it is because when i poked it with a stick it went all fat and put its arms or flippers (what ever you want to call them) over its head and it can also stick to vertical smooth walls without falling and can hop up them with ease.can it change camouflage???( ps sorry that i couldn't get it on to its back cos it will just role over again. Also please tell me anything else about it to it you can. :2)

Frog operated music player

I have a pet tree frog, Slippy. He likes to croak along with certain types of music, like minimalism and hip hop. I think it would be great if he had a way to turn on some music by like, hopping on a switch. I think he could learn. I have some ipods and a tape player. I can get more if need be, but I can't blow too much on it.

Sample and Loop Frog (Bent toy)

Hey Folks, i ordered this frog at dealextreme. com.Its called a "Digitally Recordable Motion Activated Visitor Welcoming Door Chime Frog". Originally it is a toy that says "Hello" when someone passes by. You can use your own sample, simply by pressing a button to record it to the frog. Nice toy for circuit bending i thought. Here's what i made today. I added loop, pitch control, input and output jack and a button to start the sample manually. Okay it has still a few bugs, but it works. Hope you enjoy the video:

You can help save a rare frog from extinction!

First off, I realize instructables does not want pure advertising on their site through these forms. The voting is optional and I don't want this to be viewed as advertisement. If nothing else, I want to share with you our story in the project, and hopefully you'll see how awesome this is. We are doing something that no high school has ever achieved before, and I think it's more relevant to the site than some re-posting of a blog article. I hope that you take a few minutes and find out what the Frog Project is all about! Want to support the cause of helping endangered species, education, and advancing biotech in schools? Well, take 5 minutes and vote for our school to convince Khols' to give us 1/2 million $$! Unfortunately the contest is over, but we're going to go for a $250,000 grant for a Pepsi contest in November. If you become a fan of our page (noted below) you'll be updated. Check back in November! https://www.facebook.com/pages/The-AAEC-Frog-Project/128763967175416 ======================================================== Not convinced? Well, here's our story: You can help save a rare frog from extinction, and it is free! Kohls the dept. store is donating $500,000 to the 20 schools with the most creative need for the money. Your vote can help our school win this money, and best of all it costs you nothing! We are working on a project to try and save a rare frog from extinction. And we need the cash. At our small high school of 300 students, we are trying to completely sequence the genome of a rare Arizona frog. We hope to accomplish 2 things from this work. 1) We hope to rescue this frog from extinction. 2) We hope to train a new generation of students in modern biotechnology, and rescue the State of Arizona from last place in quality of education in the United States. The Chiricahua Leopard frog is currently listed as a threatened species. We have been working in conjunction with the Phoenix Zoo and Arizona Game and Fish to develop a genetic test that could aid in conservation efforts. We have already spent a year working on the sequence of the mitochondrial chromosome of this frog. Our school actually owns a DNA sequencer. We have made pioneering efforts in the design of genetic tests for this frog. Our students have presented 5 posters on our work at the International Plant and Animal Genome conference (PAG), quite an achievement for a high school. Our project was recently awarded one of only three heritage grants: http://www.gf.state.az.us/w_c/heritage_projects.shtml By the way, the other two Heritage grants were awarded to Arizona State University and Northern Arizona University. What we really wish to do is completely sequence every chromosome in this frog. This is a very ambitious project. Consider that the human genome project completed in 2003, cost $3 billion dollars and took 13 years. Our leopard frog is estimated to contain twice as much DNA as humans! However, we think that with appropriate funding, and new technology that has recently become available we can accomplish this task in 2 years! We wish to construct what are called “DNA libraries”, collections of broken chromosome fragments of known sizes. These can be sequenced quickly using NEXT generation sequencing technology. The Chinese genomic group BGI has agreed to cover the costs of NEXT generation sequencing, and genome assembly for our project (an estimated $1 million) if our school can come up with the remaining funds needed for the construction of the libraries. We need to purchase about $200,000 in new equipment, and extend our existing lab space. With the completed genome sequence, we would like to have a custom “gene chip” manufactured. This chip will have all the DNA of the frog physically printed on it. The chip allows experiments to be carried out without any harm to any frog. This chip could then be used to aid conservation efforts by the Phoenix Zoo and Arizona Game & Fish. It could allow the exact parentage of every Chiricahua frog that is discovered to be known. Eventually this technology will become the backbone of conservation work on all species, but at this early stage it is not possible for Arizona Game & Fish to raise the funds needed to generate a gene chip before it is too late for the frog. Our school hopes to be the first in history to carry out a genome project. We hope this will serve as a guiding light to other schools, and start a grass-roots movement in the conservation and education world. Help us save our frog! Here is the catch. Vote for us on Facebook, and convince all your friends to do the same (forward this message to them), or unfortunately the frog bites it! Everybody can vote up to 5 times for us. In this way YOU can help make the difference not only for this rare species, but if we can succeed you will help pave the way to help many others. https://apps.facebook.com/KohlsCares/school/32741/aaec-paradise-valley Regards, -Mike Dr. Mike Brown Science Dept.

Injured Frog/Toad what do I do?

The frog/toad looks to be a American toad. It has a best described as a shaved head. It has a hole on the front of it's head that leads into it's mouth. It looks to be missing an eye as well. It seams to have an injured limb on it's front left. It has been alive for over 16 hours, it seams to have gotten better than when we first found it. We have fed it dried blood worms. We have not seen it eat them but they are gone from the make shift enclosure. I am worried that it may not be able to survive in the wild if we release it after it heals. That is if it heals. I just don't know what to do, please help. NOTE the water got the chemicals removed before we put it in there. We also tried to get the grass off of it by using water (again without chemicals) but we couldn't get all of it off.           We found out it has Toad Fly ( I think that is what it is called ). I am so glad It wasn't me who ran it over with a lawnmower the other day. I still feel sad for it though.

Memorizing stuff easily

Memorizing Method This was originally going to be my first instructable but I figured it would be better off as a forum thingy. This is a method that can help you remember up to 10 items. I learned this from one of my teachers and find that it is quite effective. All you need for this is a brain, the names of 10 items, very little rhyming ability, and some imagination. Rhyming words that that you need to know... ONE rhymes with BUN TWO with TREE THREE with TREE FOUR with DOOR FIVE with HIVE SIX with STICKS SEVEN with HEAVEN EIGHT with GATE NINE with LINE TEN with HEN How do you apply these rhymes to remembering stuff you ask, here’s how. With an example... say the ten things you need to remember are, computer, a grenade, frog, cow, ninja, thumbtack, phone, cereal, Kansas, and CD. Computer is your #1 item and BUN rhymes with ONE, soooooo, picture a computer in a hamburger bun STOP! Visualize this image for a moment, and then move on. A grenade is your #2 item, TWO rhymes with SHOE so picture a grenade in a shoe STOP! Visualize this image for a moment, and then move on. THREE rhymes with TREE, so visualize a frog in a tree or a tree frog STOP! Visualize this image for a moment, and then move on. FOUR rhymes with DOOR, word #4 is cow, so picture a cow stuck in a door or something like that, STOP! Visualize this image for a moment, and then move on. FIVE rhymes with HIVE, like a bee hive, so visualize a ninja fighting bees or something. Okay, #5 is the last ex. I am going to explain, you should be able to figure out your own images for the rest.

How to compete with neighbors' lush lawns and catch toads?

I am in the process of attracting and catching a toad for an Instructable. There's a few problems with that, but none so big as this: Toads like moist environments. It's a fact. My yard - dry as the Sahara. Well, maybe not that dry, but compared to my neighbors' lawns, it is. My neighbors have nearly constant sprinklers, pools, buckets of water (or as I like to call them, mosquito farms), and always-on exterior lights. In case you don't know, that's nearly heaven for a toad/frog. I go out at twilight/dark to find a toad, and I hear them everywhere - except in my yard. I'd go get one from my neighbor's lawn, but that'd be trespassing, and for a dumb reason. Do any of y'all know of a way that I could turn the toads' attention from my neighbors' lawns to mine? I can't do anything major, like building a pond, but any little things to bring them closer to my home would be good. Thanks, and if I can get a toad, expect to see an iBle coming from me! (Note: substitute frog for toad if you want - it's just that toads are more terrestrial and would in theory be easier to catch.)

Cat Scan - patches available

From Tumblr, via Animal New York, via Notcot, comes The Cat Scan. It's cats. On scanners. It's weird, yet somehow obvious.  The blasted animal has fallen asleep on your scanner again, so why not try and teach it to sleep elsewhere? What's the oddest thing you have ever scanned? UPDATE I've decided to arbitrarily award patches to any scans people upload. Rules: It must be something you've scanned yourself. If it was alive at the start of the scan, it must be alive and unharmed at the end of the scan (ie don't hold frogs still be pressing down on the lid). International entries are absolutely allowed.

GameBoy Advance overly saturated screen... How to fix? Answered

I got a GameBoy Advance a few years back, the Nintendo DS of last decade. It worked great for about a year and then (I think I may have dropped it) it started displaying the colors on the screen way too brightly! Nothing else was effected, but the screen looks as though it doesn't know what "dark" means. All of the games I try to play are way too lightly-colored, to the point that I can't see any details at all. As you can see, I try to play Frogger's Adventures: Temple of the Frog, but I can barely see where I'm going because the screen is too saturated. Oh, and another thing: After the screen started doing this, I dropped it once more, and it switched back to normal for a time, but then after 30 seconds, it flipped to the higher saturation again. This would lead me to thinking that something is broken inside... Is there anyone out there who knows of this problem, and perhaps, knows how to fix it? Thanks, Win Guy

Chemcial Question for Taxidermy Related Project

I am quite interested in the articulation of the bones of animals. I plan on using small game (squirrels, frogs) to begin with, and I will probably donate them to my Biology teacher, since she loves skeletons.The process of defleshing and whitening the bones of the animal is fairly straight forward - soak the carcass/skeleton in chemical baths and take it out when it's done. The chemicals needed for the process are what's going to be hard for me to obtain.I need a 0.3% solution of sodium carbonate. Sodium bicarb is extremely easy to come by, but I've never seen sodium carbonate. I've heard it is used to raise the pH in pools, so I'm guessing a pool store would carry it. But, would it be possible (practical) to make it? Is there a way, using household chemicals, to produce sodium carbonate? I don't need very much.Secondly, I need a 20% solution of hydrogen peroxide. I only have a 3% bottle. I've heard H2O2 is some pretty dangerous stuff. Again, is it possible for me to buy/make it? Would freeze-purifying it work?Thanks for any help, and if I get this to work out, of course it'll all be turned into an Instructable.

Back from the Big Peach

Back from Ole Southey, The Sweaty Apple, Ted Turners Bidet. Yep, talking about Atlanta Ga. and thanks to the interweb I can annoy millions with my travel log.If you like you can check out my pix, I took over 1400, but didn't put all of them online, sorry about the low quality and the image tag, I get tired of finding my pix on other's pages.So my wife and I stayed in an inexpensive best western in midtown, alright hotel, great location, thin walls.We visited the Ga Aquarium, we were underwhelmed, perhaps spoiled by multiple trips to the Shedd Aquarium we were disappointed in that it took only three hours to tour the whole facility, TWICE. The whale sharks are cool, but the cafe is to be avoided, the "burgers" I ordered still had ice in the middle.The Atlanta Botanical Garden is an absolute jewel, I've visited dozens of gardens and this one tops the list, the highlight being the Fuqua Conservatory where you share the environs with poison arrow frogs, along with an outstanding orchid house.The High Museum, is hard to judge, we visited the special exhibits only, it was interesting to see a Rembrandt in person, and the Annie Leibowitz gallery was nice.The Fernbank Museum of Natural History, this one I sadly say, pass on. I LIKE dioramas and natural history museums, but without the Imax movie, it would have taken 45 minutes tops to see the whole thing.Finally the Zoo, a must visit, be sure to visit on a week day, Atlanta seems to be populated entirely with soccer moms witha sense of entitlement and double wide strollers. The zoo has pandas, but the red pandas have greater charm and charisma to them, and you don't need a special ticket.FoodThe only restaurant we dined at worth noting was the South City Kitchen, the food was so good you'll mourn that you will never eat that good again, the She Crab Soup and Catfish Ruben are delicious.And Weissenheimer hambergerler, PM me, Okay ?

Relativity and why E can't really equal m²

See this topic as something that should be in our now deeply missed random fun section.Everyone learned in school that there was Albert Einstein and we have to thank him for bringing humanity into the next evolution.At least in terms of understanding the universe, quantum physics and things like this.Over the years I developed my own funny theories on why Einstein was so stunned that his calculated energy output from the first nuclear test was off by a factor of about 4 - meaning his calulations were at least 4 times lower than the real thing....The official story about this "mistake" is something like this in a destilled and drastically simplified way:"We did our best but this totally new terrain, theory got corrected by real world test.We now know how to factor all this in correctly for selfsustaining nuclear reactions with a critical mass."The real explanation with all calculations and so on was document of about 200 pages....The inoffical story about the first test and the corrected results was a bit longer and personal.Nicola and ALbert had a long hate-love relationship.Similar interests and theories got them together, diference in the opinion what can be put into our current math system for calculations and conflic of used terms got them apart.But like every good couple they always got over their differences and corresponded again - sometimes with a year or two before they were ready to talk to each other again.In this story Nicola had massive arguments with Albert about the required, sustained and released energy levels for Gadget - the first test of the Trinity series.To give you an idea why it was so hard for both to understand the other or to accept the other's calculations:Einstein based all his theories and what we use today when it comes to math.Tesla however prefered his own mathematical system, one he promoted and got into every day use in many US schools at the time.In simple world it was based on a big circle, I like to call it the circle of math.Almost all of our natural constants (that were known back then) were present as lines, multiplication, squre roots and more were as easy as following the right lines and pathways indicated on this circle.Both system, ours and Tesla's provided the exact same results, the later however without any need for additional "notes" along the way or complicated formulas.And even worse when it came to energy.Back then science alrealy knew there is more than what our laws of physics state and what we know.And what we could not really understand and only proove in theory is now as common as butter on your bread.Thinks like quantum mechanics, quarks or the fact that you can't observe a light particle on a quantum level directly, only as its sum....Tesla however already had "a higher understanding" on how different energies interact and how get from one form of energy to another.Like his tesla transformer, the radio transmitter and so on.While we had no clue at all Tesla already studied the ionosphere, he had different name for it though.For him it was obvious that it is not just a reflective barrier for radio waves but that it also has a very energy potential on its own.Either way the argument was the Albert only factored in the mass of the nuclear material, the explosive forces from the ignition and the corresponding implosion.Basically everything we could see, explain or theorise about back in the day - and it needed to be possible to claculate it somehow to match expections.Nicola made the claim that during the explosion also a lot of electromagnetic energy is created together with what he called a break in the fabric of the universe.Not only that but the electromagnetic shock (we call it now EMP) is not really a single thing but spread basically over the entire know frequency range, including visible light.The visible light claim was confirmed during the test by shadows burnt into walls....You can clearly imagine how good old Einstein must have felt seeing his good friend being dead serious about things he could not have the slightest idea about.After all there never was any test before and certainly none with Tesla present...How the personal story between the two continued can be found online if you some digging or if you prefer in a well stocked library - yes they still exist as real place ;)What was mostly left undocumented, at least for public eyes was the implications from the Trinity test series.That Tesla really was onto something even if the smartest man on the planet could not understand a single word of it became painfully obvious.At least for Albert....In his later theories you can find the influence the revelation of finally understanding why his calulations were of and most importantly understanding what Tesla meant by the fabric of the universe.E does not really equal mc² for quite a few reasons.Firstly because it is based on the assumption that nothing can be faster than the speed of light.So did our best to measure it, cheated by making definition of light speed and meter based on the same thing.I mean: If you take two "unknown" variables to create a result and then use the result to finetune the input- how accurate can it really be?....Today we long know that there things travelling much faster than the speed of light, for example gravimetric shockwaves when a distant star goes booom.We detect these "gravity quake" now so we can aim our big telescopes to where it happened and see it in "realtime" once the light arrived long after the shockwave.And if you dare to re-do the original calculations for Gadget and factor in that a gravimetric shockwave travels about 4 times fast than light you get an idea why Tesla already knew all about it.What came out of all the offcial calculations and theories is well known.What is missing from E=mc² was never officially published by Einstein...Applications for the possible damage to what Tesla called the fabric of the universe.We are trained to only use our brains in two dimensions.A bit of it comes from our evolution as since the dawn of time we prefered creating a flat image over creating a sculpture with similar details.Some people though can use their brin in three dimensions with ease, like when a really good sculpture artist say "The sculture is already in the rock, I only need to remove what is covering it."And sure enough every color or texture detail of the rock ends up in exactly the right spot to make the result perfect.Musicians are quite similar, a lot of them have no clue about notes or how read them to create a nice tune on an instrument.Some only need to hear a song once and can repeat it on all instruments they play like they studied the song for years.Others hear the vocals only and create tunes and melodies from it that not only match voice act but also reflect on the mood, the feelings.In some really good songs you only need to hear the instruments and can almost imagine what the singer would sing to it...A very few can do similar with math, we like to call them a genius because we can not imagine a complex and long number as a series of meaningful images or emotions paired with colors - for example, as there many more ways to deal with numbers...People like Einstein realised after the Trinity tests that the EMP and corresponding electromagnetic effects are too strong to be measured by anything unless it is from a great distance.That means, like lumen per area, the strenght of the electromagnetic effects increase exponentially the closer you get to the source.Still... No big deal right?Well if you dare you make a frog levitate in a magnetic field, won't be a healthy experience for the frog but it will levitate.You can look these frog experiment and corresponding scientific explanations up online if you are bored enough one day.The point is: If a frog can be excluded from gravity in a magnetic field of suffient strenght, orientation and other features, then what else can "float"? ....Or more to the point: Why exactly does the frog float if he is not magnetic enough to begin with?....We have no problems visualising or imagining the shockwave from a big explosion like Gadget.High speed films show us that there would be an expanding perfect sphere, only object like the ground limit this experience, but you see it nice in underwater explosions!What most people can't even begin to understand is how a shockwave of which the EMP is only a small part acts, travels or what effects it migh thave.Unlike a normal shockwave we have something like redox reaction happening.The explosion creates an unimaginably strong electric impulse, a bit like all lightning strikes in world feeding into a single lightbulb at the same point in time.For argument sake lets say is almost indefinately high.However, like in an ignition coil this impulse creates and equally strong electromagnetic impulse.And since the entire reaction at this point is far from over we get a harmonic resonance and feedback system.Imagine a second you stretch around the globe as a band and then you cut a mm off it - that would be about the timeframe for the most intense electromagnetic field swinging around at all sorts of frequencies.And during this very short period of time a bubble is created that expands what modern sciensts now call the space - time - continium.Same name as in the movies but this time based on quantum theories and such things to explain gravity.An awful lot of energy is trapped inside this bubble and once the initial reaction is over the electromagnetic impuls disappears and only the normal reaction from the explosion continues.The bubble however does not pop or disappear, it implodes.All this energy is compressed basically to a single atom size and released.Sadly this energy has no visible effect, nothing we can observer with our eyes or instruments...Again we use quantum theories to explain what must happen to find way to it "visible" somehow or to find way to really measure it.Gravity sensors are a result of these theories and developments and now part of basically any good GPS satellite or space probe.Some fancy phones have them too.What would actually happen if we would have found a way to affect the space time continuum in a very controlled way?Without explosions or such bad things, just by using simple technologies.Now I would have to explain things in at least four dimensions, which means most readers would shut off now.Using five would be insane, I know :(So let try to ignore how things work fr real and do what every good scientist does: simplify to make the imagination work in just 2 or 2.5 dimensions.Put a cork on a pond a throw a rock in it.It moves, mostly wobbling on the waves but it moves away from where the rock was dropped.If it could be "anchored" at the right spot between two crests of the wave it would move with it, like a surfer on a good wave does.A craft that creates our field from the inside and in a neutral configuration would create a perfect sphere.What would that mean for the craft and those outside observers?At a first glance nothing until you realise the craft has no mass at all.You could lift a 5 ton vehicle with your little finger and flick away like something you found in your nose.Unlike our suspended frog the craft would create a field bubble where gravity diverts around it.Gravitity is the driving force of the space time continuum.Without it there would be no time, without time there would be nothing.If you would be inside the craft and be flicked away by a finger you would only realise it if you looked out of window or onto a screen showing the outside.As the craft does not exist in the normal space time continuum, so to say, the same non existing effects of things like acceleration, g-forces and such can't apply for what is inside either.Well, at least until you reach the wall, the suddenly all is stopped and has to enter our normal continuum again.You would be mince meat on some wall inside what is left from your craft...Increase the field strenght to overcome inertia of smaller particles and even air molecules or dust particles are diverted around the field.Nothing though that would rival the mass of the craft in a significant way, like flying into a solid wall or mountain....A modfied field geometry allows to affect the shape of the bubble.To keep it in two dimensions, imagine a ping pong ball as the field that you press into some slime, or similar fun stuff.Start moving it and it forms something like a wave in the front and something like a wake on the other side.Our field can shape the bubble so that our space time continuum would look quite similar - if we could see it instead of theorising about it.As result the craft now moves in our normal continuum without having and appearent form of engine.The bigger you make these "waves" with your field, the fast you go....And suddenly those impossible movements in the sky that are always dismissed as a hoax or weather balloon make a lot more sense.Be it a Scalar drive, the Fluxliner, VR7 and derivates, they all use garvity as a propulsion system.Fair enough you might say, but what does mean in terms of where we might have been already since almost one hundred years....A gravity based drive system in the sience fiction section has many names.Warp Drives of course comes to mind first.But also FTL drive or Jump Drive.Just because gravity waves are much faster than light already means lightspeed is not really a limit and hasn't been for a very long time.Why do you think superconductors were first developed by/for the military? ;)With no mass it is only a matter of the avilable energy how fast you can accelerate and what top speed you can reach....Or to be precise: How effiently you can create an insanely strong electromagnetic field.Make you wonder what else came from understanding what things like a Hedron Collider can do...With an estimated energy output equal to truck sized generator you could make it from Virginia to Mare Tranquillitatis in about 10 minutes.Make it 30 if you want to get out and stretch your legs when you are there.Some now say "I don't care who or why someone goes to the moon."But what about those who think climate change is real and how we produce and use energy plays a big role in it?Let alone those actually considering that fossil fuels might run out one day....If you have a gravity drive then you have a very neat way to create almost limitless, clean energy.....I leave it up to what it would mean if everyone and everything in our world would have access to free and virtually unlimited energy....Isn't it good that all this is just a nice story and that all is just fiction with no relation to reality?But if E does not equal mc² then how relative is our reality really?

Caring for a toad with a broken and infected arm? Answered

Last weekend I found a toad with his arm trapped in a mousetrap.  I don't know exactly how long he was there, but I discovered him when I heard this shuffling sound from the back of my garage and heard flies buzzing.  Upon investigating, I found poor Toady.  The flies had already laid eggs on his wound.  He was trying to hop away attached to the trap.   His arm is clearly broken.  He didn't have significant blood loss, but when I first opened the trap his tiny bones were visible at the injury site. I put Toady in a small bucket lined with moss and vegetation, along with adding a little bit of water, and covered the bucket with a dishtowel.  I used cotton swabs dipped in saline to clean the wound and applied antibiotic ointment (Neosporin without painkiller).  I also tied a thread slightly above the injury site to act as a tourniquet and prevent further infection, and possibly allow for his limb to naturally come off. Below the injury site is swollen, discolored and infected, growing a fuzzy fungus.  I've been checking on Toady every other day (I wasn't wanting to stress him out too much with frequent visits), cleaning his wound and infection and applying antibiotic ointment.  His arm is clearly dead weight and can't be salvaged.   I've put various bugs, slugs/snails and worms in there with him but I haven't seen him eat.  I put a june bug in there, and the june bug ended up trying to climb onto him but Toady seemed to try and squash the bug with his chest and then hopped over the bug to the other side.  Maybe the beetle is too big for him.  I haven't checked to see if the other goodies I gave him are just hiding under the moss. He doesn't appear to be losing or gaining weight.  He gets stressed whenever I visit, breathing rapidly and either trying to make himself look larger or do the opposite and huddle down, despite how careful and gentle I try and be around him. I'm worried about predators and infection if I were to release him now.  What should I do/not do?  I think I'll try Craigslist here to see if there happens to be an experienced amphibian owner with the proper supplies to care for him.  I doubt any vet here would be able to do anything, and I don't have the money to do so. Is this toad a male?  I thought he was based on his size since he's on the small size, but perhaps it's a youngster?  He doesn't make any noises with me, but I'm not sure if it was him chirping in his bucket or a nearby toad.  I know there's several right in the immediate vicinity.

Leaving China and Taking a Part With Me.

My time was short, it seems my time is always short. Groggily I was pulled from bed the day after the Maker Faire. Spending the night at Eric's place was so wonderful, it was my first nights sleep since leaving America a few days earlier. We loaded Eric Pans car with gear and headed out to pick up a 3D printer. 3D printing technology is booming in the states, nearly every hackerspace in America has a Makerbot and design firms have Shapeways to turn to to get their rapid prototyping. But elsewhere in the world these things are still fresh! Sharing tools is something I love to do because you never know where people's creativity will take them. You never can know all the problems in the world, but all the people know all their problems! One of my missions then is to share low cost and open technologies to people I think can make awesome use of them! The night before after the Shenzhen Maker Faire all the Makers were invited to a gathering. Beer, frogs on skewers and peanuts were all provided free of charge. We ate, drank, wheeled and dealed. Wiess Tech is a filament company in Shenzhen and they have started noticing that more and more of their customers were 3D printers. Especially DIY 3D printers. So they've begun to make Makerbot replicas with some modifications. And there I was - I wanted a 3D printer to bring with me to Beirut and they wanted… Well, I wasn't sure. The language barrier between us was strong. Somehow Eric and I convinced them that it would be a good idea to give me a machine, and perhaps I'd pay them back when I got to the states. At this point I was at $244 dollars and dropping and I couldn't even afford the incredible hackerspace price the company was offering of $500 dollars! They agreed, and that's how I found myself rushing off to their head quarters the next morning before catching my ship. But first. We must go to Seeed Studio to buy a cup of coffee from the robotic tweeting (QQ) coffee machine in their break room. Hahaha! We headed out to Wiess Tech and on the way there we drive by construction zone after construction zone. Aparently Shenzhen didn't exist 30 years ago, and now you can still see the signs of a rapid expansion. Everything here is growing at an incredible pace, and apparently even maker culture. We arrive at Wiess HQ, which is housed in a 30 story complex decked out with multiple confusing entrances, cafeterias and dual elevators for the odd and even numbered floors. After spending a bit of time wondering how to get to floor 22 and circling the building, we found ourselves face to face with a small crew of about 8people. A few people managing papers, a secretary, some of the marketing team, and one guy sitting at a table putting together Wiess Tech versions of the thingimatic. After speaking with them we find that they also sell a machines based around the Reprap project, one of the earliest open 3D printing projects and have in the works a few models of their own designs. I'm excited to see how Weiss Tech bootstraps itself off of open sourced designs and starts producing their own versions! I hope to see a whole new generation of better, faster and cheaper machines that stay open! Go Weiss Tech! Heading out to take a 3D panorama from their deck Eric rushes and tells me that my ship leaves in 20 mins and that the time is now. After an awkward moment or two talking about paypal and me giving them advice on staying open we undo all their packing (too bulky) throw the machine into my luggage and run. In the car Eric and I discuss the future of Chinese makers. It really seems this is just the start of something much larger. It's an exciting time, his company is building great products, more Chinese companies are looking at open source technologies and more people are calling themselves makers. Perhaps it's through Maker culture China will be able to become more than the King of manufacturing, but also participate in producing quality designs and solving serious problems. Leaving China, the baggage handlers on the ferry were rough handling Adriana, my 3D printer, and it really cut deep. But as I watched Shenzhen bay slowly recede, I knew the next time i came back, again, everything would again be different. This is the pace of China and yet it seems softened by the fog falling over the rolling green hills. +Bilal Ghalib

Question on using a Peltier/TEC device for air temperature control - Help please.

I want to have some control over the temperature inside the Orchidium I'm designing and I thought it might be cool :) to use a Peltier Device (device aka module) (Peltier aka TEC or Thermoelectric Cooler). I find I need a lot of help! (Please!) Alright, this isn't a completed Instructable, it's a plea for help, and maybe if the subjects lie in some of your fields of knowledge then we can all enjoy and learn from it. So, the Orchidium I'm designing is an acrylic case 24"W x 18"D x 30"High. It's to grow species orchids indoors in a microclimate, with LED grow lights, proper humidity, air movement and temperature control. (Of course, other critters would like the case, too: poison dart frogs, newts, carniverous plants, etc.. But I'm going to call it the Orchidium.) I've got it all pretty well planned out so that it can be built for a very reasonable price (yes, including the LEDs) and still be aesthetically pleasing and real purdy, too. All planned out EXCEPT FOR THE TEMPERATURE CONTROL. I was looking for some way to cool my case and I stumbled across Peltier devices in eBay. They are CHEAP, costing about $5 or more, depending on the Wattage, etc. The eBay sellers intimated that all you have to do is plug them in and the device gets ice cold. Later, with diligent web-study I learned that actually ONE SIDE of the peltier gets cold, while the other side gets hot. Also, you MUST attach a heat sink and fan to both (?) sides of the peltier. Also, that these devices are not ready to be plugged in; you must attach a DC power supply to them. Oh, another trick that these miraculous devices do is reverse their hot & cold sides when you reverse the polarity of their juice. Ideally, I would like a Peltier device with heatsinks, fans, a thermostat and a DC wall transformer attached... the Peltier/heatsinks/fans would measure about 2" x 2" x 6" and would be mounted in the sidewall of the Orchidium. When the temperature is 65-85F degrees the orchids are happy and the device is Off. But when the thermostat senses the internal temp going over 85F it turns on the Peltier, cold side inside, and so the inside of the case doesn't go up to 90-95F like mine does now; it cools the case a little. Conversely, for someone with chilly orchids or sneezing newts the thermostat would switch the Peltier to hot-side-in to heat the Orchidium a bit. The retail cost for us to buy a Peltier device, 2 heatsinks w/fans and a DC transformer is cheap... roughly $30. The thermostat might be cheap, but I don't know enough about what's needed. If it's too expensive then the Orchidium can do without it. I was hoping I could find an off-the-shelf Orchidium cooler/heater. No such luck. These miraculous Peltier devices are still practically undiscovered -- relatively speaking. People want to use them to cool their computer chips but are hampered by condensation; my orchids welcome condensation. Pathetically, it seems the most common use for Peltiers now is to cool/heat the little boxes on your car seat... they plug into your cigarette lighter and keep your 6-pack cold. Come on! You folks at Instructables can surely help me figure out how to best make an Orchidium cooler with this barely-discovered and poorly-utilized device. I started out a few weeks ago writing to many of the Peltier manufacturers around the world in hopes they might help me in choosing which of their modules I might purchase for my Orchidium. None of them was any help. They wanted to know how many million Orchidiums I planned per year. They told me my basic plan was hopeless or inefficient cost-wise. A Swedish company wanted $800. An American company wanted $500. Some other company wanted $5,000 to $8,000. I wrote back and said I could get a Peltier on eBay for five bucks. The Swedes snottily claimed that their Peltiers were very high quality. No. No way is any svensker Peltier $795 better than ANY other Peltier in the known universe. They both get cold and grow ice crystals on one side. I just need to cool the case A LITTLE BIT, like from 90 to 80 degrees Fahrenheit. I am not trying to make a refrigerator or freezer. The case (Orchidium) is large, at about 7.5 cubic feet, and there is practically no insulation. Acrylic provides a little insulation, that's all. The temp of the interior of the case is derived from the ambient room temperature of your house... and the lights... which is why I designed it with LEDs. There is a constantly-operating muffin fan inside the case to provide air movement for the plants, but it does not provide any evaporative cooling since it's a closed case. So, first off what size Peltier do you recommend... do you think a 40 Watt would be enough, or what? Next, the placement. I envision the Peltier device mounted vertically through a hole in the side of the case. It might be a plan to mount it in the ceiling, but remember that the LEDs take up most of the ceiling. Next, the heatsinks. I confess I'm not totally clear on this, but I "think" that 2 heatsinks-with-fans may be needed, with one sticking out the outside and the other inside the case. I went ahead and got 2 heatsink/fans from Newegg for supercheap ($1 after rebate), but they aren't really what I want. They're actually shaped to fit some AMD chip. What I think I need is a copper heatsink with a flat bottom a little bigger than the Peltier, and fins... and a heatsink fan attached... and some way to attach it to the Peltier, and through the case to the other heatsink. See? Simple... well it should be but I can find nothing. Next, the power supply. I know it has to be DC, but I don't know which brick to get. I did find a bunch of DC or AC Wall Transformers for sale at alltronics... around $10 or so. All that stuff would be enough... at least to test the cooling power. But if we want to go whole hog then the icing on the cake would be thermostatic control of the Peltier. Well, I throw that out in case one of you is sharp in that field.
