Adding an instructable to the Deconstruction Group

Hi folks - The Rabbit Hole team here from the Deconstruction... We uploaded an instructable for the Deconstruction group from the Rabbit Hole team - rather than do this a million times (and not see it in the group), is it awaiting moderator approval?

What the BLEEP do we know?

How many have viewed the movie or read any of the books enititled: What the BLEEP Do We Know? [ What the BLEEP link]I just viewed the shorter version of "Down the Rabbit Hole", and would like to have some opinion on whether it is worth my while to veiw the extended (6 DVD) version of it?

Life size Pokemon in a toy Pokeball could be possible!

Oh how I cried when I realised that I would never catch a Pikachu. I should probably collect my used Pokeballs... Anyway, I was out in the woods looking for wild Pokemon, when I had a eurika moment, (I had actualy fallen down a rabbite hole full of moss), for some strange reason I thought of those auto pumping whoppie cushions (probably the spongy moss) and then realised: If I could create a fabric Pikachu or buy an inflatable , I could fill it with foam then scrunch it up as small as possible, and put it inside a Pokeball! I think it might work, so I'll give it a try!

The FootHold Snare

One day, you might find yourself lost in the woods while camping! One day, the stock market will crash and are YOU ready to survive? Traps and Snares are one of the most important things while surviving. Blake Alma, the founder of The Art of the Outdoorsman once said, "A trap is as someone else hunting for you when you can't, it is truly your best hunting buddy!" This is so true. Unlike fishing poles and firearms, traps and snares work when you are sleeping! Hence, learning how to make a simple snare indeed helpful and lifesaving for it is an art of an outdoorsman! Let's get started on this foothold snare. You need: A shovel, 550 lb. test paracord, and bait. Note: There are laws regarding trapping. Step 1: Digging your Hole Picture of Digging your Hole I hope you got a good shovel and back! You will need to dig a hole 2 to 3 feet deep. Yes, I know it is a true pain, but it can save your life or get you free food! Diameter of your Hole: - Raccoon/Opossum/Mink/Groundhog/Large Rabbit (6 inches) - Coyote/Fox/Bobcat (8 inches) - Animals under 550 pounds/Deer/Small Elk/Very Small Bear/ect. (12 to 18 inches) Step 2: Camouflaging After digging your hole, add leaves, thin sticks, tree bark, or grass over the hole. Do not put to much "camouflage" over the hole or else you may prevent the animal from falling down in the hole. Step 3: The Snare Wrap the paracord around a stick or you finger making a small loop. Tie the small loop, and pull your finger out. Make sure the knot is very strong. Put the other end of the paracord through the small loop. You should then have a giant loop, known as the snare itself. Make the loop's (snare) diameter slightly smaller than your hole's diameter. Tie the snare extra line around a tree, sapling, or log near by. Make sure it holds. Place the snare itself over the hole, on top of the "camouflage". Step 4: The Path of the Least Resistance Sense the animal has plenty of ground to step on, it might be hard to get him in your hole. Hence you need to create a the path of the least resistance. You need to make him limited to where the animal will step. Make a path to your foothold snare using leaves, sticks, logs, and grass. Make it easy for the animal to walk through. Like us we want to walk on a nice smooth sidewalk, not on a beaten trail. They want to walk on a path with the least resistance, they don't want step on pointy sticks. They want to step were the feel most comfortable. That is way you need to make a path to your snare, so it will step into your snare! Step 5: Baiting your FootHold Snare Picture of Baiting your FootHold Snare Place your bait two to three feet ahead of your foothold snare. Raccoon and mink like fish. Opossum like processed meat like hot dogs. Groundhogs like sweet apples. Coyote and fox like meat. Deer like deer feed (duh!). How it works: The animal will smell the bait and take your path of the least resistance. While walking up to your bait on the path, he will step his foot in the hole. It will pull his foot out of the hole and continue walking. (When we pulls his foot out the snare comes out with him.) Then the snare tightens around his foot, making him trapped.

Can't Fully Add Instructables to Our Group

Hi there instructable wizards! I'm the admin for a somewhat new Instructables group and we're having trouble adding our Instructables to our group. We found two ways to attempt to add an instructable to a group - Go to the group page (in our case The Rabbit Hole) and on the right hand side press the +add your Instructable Or - Go to your Instructable and on the middle right there is a Add Instructable to "Group" button Either way, if someone uses these options, as one of the admins, I get an email saying that a new add request has been submitted, but then when I follow the link to the admin page, there are no pending instructables to approve. I've tried this many times on Windows 7 in FF, IE and Chrome...also tried it on Linux in FF When I visit the URL I see the image included here:   It says 12 items found, displaying all items. 1 But willschm and another member of our group have already submitted new projects that should be in the pending section Also noticed that something considers that I have added an Instructable to the group because I can't attempt to add it again from the group page thanks fro the help!

1 Arduino + 3 or 4 LM35s?

I am a total beginner, having logged about one hour here (the last hour). Does this sound OK for a first Arduino project? I want to sample and log the temperature outside at the surface and at depth for a total of 4 readings to a depth of around 50cm (20"). The reason is to consider if I should provide my daughter's pet rabbits with an underground burrow as relief against the next heat wave. It seems a nicer option than running a swamp cooler all day. Though I suppose I could use an Arduino + LM35 to turn on and off the swamp cooler :) It looks like I can do it with 4 x LM35s, an Arduino One, some sort of data storage, a 9v battery and a bread board. Any recommendations for if I should use WiFi or an SD card for storage? My guess is the SD card is simpler to programme and maybe less of a battery drain. It seems I just need to hook up the data out of the LM35s to the analogue ports, then loop over the inputs and write the outputs to a file somewhere. And calibration too. Any pointers on how to turn the LM35s into probes that can be buried in the ground? I was thinking I could bind all the probes onto a dowel, dig a hole and bury it. How to extend the LM35 pin outs? Thanks in advance for any suggestions.

I want to learn how to build a vacuum tube guitar amplifier

I have a slight issue that I am sure a lot of you do too... I have a million interests, hobbies, and maybe even some borderline-diagnosable passions. My problem is, I am 40 years old already, and I do not have years left on Earth to become a full-system level electrical engineer, a full-stack software engineer, and a master carpenter... just to name a few. So, I am looking for the best resource that you guys can suggest for where to start so that I can learn how to build a tube amplifier along the lines of a Fender, Marshall, Vox AC30, et cetera. of course, I do not aspire to revolutionize, or even evolution-ize guitar amps, and I also do not aspire to build some esoteric masterpiece copy with three independent channels, each with a separate EQ, a foot-switch, and multiple ins/outs. I just want to build a simple, 1-channel amplifier that has enough power to produce a very clean tone without distorting, but has a gain, and a master volume so that it can be "pushed" to produce a distorted sound. I do not care at all if it sounds "good." I just want to do it, and I do not want to have to spend 2 years going down a Nikola Tesla rabbit hole trying to learn every theory of physics, electronics, etc. I just want to learn how to construct the circuit(s) and not electrocute myself by being dumb. So, don't get me wrong... I want to learn the right way! Just looking for a good resource. has dozens of books with titles that all sound the same. Does anyone know of the quick-and-dirty-bible for this?

Looking for a Gear Set for 3D printing

A little over a decade ago I spent a large amount of time playing with lego technics. These mechanical legos had a set of gears with them that you could arrange in infinite variations and I loved them (still do.) What I would really like is file with a standard set of small gears that I could easily place into a 3D model and design around just like building something out of technics. The difference being that I get to design the parts connecting the gears instead of using lego bricks. These gears would ideally range in size from 5mm to 30mm diameter and would ultimately be used to make 8 inch or smaller robot things. Now, the obvious solution is to just make them, Inventor has a generator and they can be drawn in almost any program. The thing is that, well, it is over my head. I've used a lot of Sketchup, but am just getting into Inventor and 123D. Also, it turns out gears are incredibly complicated. I've looked at the diagrams and between the pitch diameters and diameter pitches and pressure angles I get lost, I'm not even sure where to start. On top of that, in my research I haven't found any kind of standard like there are with screws and electrical components; one can't just call the robot store and say "gimme some A5 gears good sir." So my questions are: 1. Is there a simple standard for gears? Specifically small plastic gears like those found in toys and clocks. 2. Do you have any advice on how I could go about creating my own "standard" set of small gears, like most important factors or common pitfalls, a magic button? 3. Am I going about this in a weird, round-about, wrong way? I'm learning as I go with 3D modeling/printing and I often fall down rabbit holes, this may be one. How would a professional engineer who is designing a toy go about choosing or creating his gears? Thanks in advance for any insight you can lend. These are the lego technic gears that are so dear to my heart
