The Ikea Chicken Coop

Ikea has served humans so well with its affordable home furnishings, but what about the chickens? Urban chickens want some of that Scandinavian style too and who are we to hold them back? That's why Aaron Bell and wife Corinne created this new chicken coop that is largely made from four different Ikea items. Check the link below for more details. Ikea home for chicks via make

Light Sensitive Chicken Coop Door

Hi, I recently started keeping my own chickens and have really enjoyed the whole experience. The chickens were all really friendly and provided hours of amusement. Until a few weeks ago I had 4 of our feather friends in a nice Coop. That was fine until one night, for the first time ever, we forgot to close the door to the coop. Unfortunatley the fantastic Mr Fox must have been casing the joint for some time and siezed his opportunity. Three of the chickens were nowhere to be seen, the fourth lay dead under our rhubarb. So why am I telling you all this sad tale? well, I have stumbled accross a solution to this ever happening again. On Ebay I can purchase a 'VSB Automatic door opener', but it'll cost about £100. This is also not ideal as by current door for the coop opens horizontally not vertically, which would mean replacing the door. I'm also concerned that the light unit will be underneath a roof with this design, so it may close prematurely, leaving the chickens trapped in the yard. I'd like to have a go at making my own automatic closer for the coop, possibly solar powered (with a rechargeable battery) that could be mounted to the side of the coop. I don't mind adapting the door to make a vertical opener, if that makes the project easier. The specs for the bought units are: Compact geared motor with steel gears ensuring extremely long life. Battery life now 3 to 4 years with an HS sliding gate or 2 years with a 1.5-kg sliding gate featuring a 50-cm lift. Dorkeeper operates considerably more quietly now. Thanks to 40-kg breaking strength, the rope can hardly break any more. Electronic shutdown of motor within one second when the sliding gate is blocked.Once the blockage is removed, the sliding gate will be opened within three minutes. The strain on the batteries is virtually negligible. Tensile force: 200 g to to 3 kg, with idler UR on the sliding gate (pulley) 6 kg. Does anyone have an ideas how to make something suitable/similar? I have included photo's of the coop showin the current method for closing (Metal foding arm)

Large Boston-Area Cooperative Fabrication Facility Seeks Members

A friend writes:Need to do some machining? How about electronic assembly? Want to join a community of other people who are doing the same sorts of things?A new collaborative fabrication facility is starting up in Somerville, and it's seeking additional members. This will be a nonprofit enterprise, supporting the rental of space and buying additional high-end tools via memberships. A membership gets you access to three different spaces:o A 2500-square-foot wood- and metalworking shop in Union Square, with industrial-sized table saws, lathes, mills, drill presses, grinders, sanders, MiG and TiG welders, and so forth.o A smaller fab shop in Davis Sq with smaller and/or lighter-duty versions of some of the same tools, for smaller projects.o An adjacent space for hacking electronics, soldering, hanging out, using computers, etc. This space is likely to have a darkroom as well.The current plan is to have the two smaller spaces available 24x7, and the larger space available all day and evening but probably not overnight.This venture is just coming up; the spaces will be available for use around Oct 1, and tours can be arranged beforehand. We've had several introductory meetings to tell people about the space & will likely have another one soon if there's additional interest.We're already mostly at the number of members required to break even; additional memberships will help pay for higher-end stuff like lasercutters and so forth. If this turns out to be so popular that the shops are likely to be too crowded, there will be a waiting list for those who sign up too late.Membership prices currently range from $100/month to $1000/year, with various amounts of storage on-site if desired. Membership prices for those who join after the introductory period will likely be higher, to help support buying more expensive toys.Some early pictures of the larger space are below (taken during a tour a month or so ago); not every tool that might appear in the pictures will be there when it opens, and there will be significant improvements in the space sometime soon, but it should give you an idea. The other two spaces don't have photos available yet (in fact, we're currently doing demolition & remodelling in one this week).http://flickr.com/photos/27076997@N00/sets/72157603801290559/https://www.new.facebook.com/album.php?aid=144093&l;=31aac&id;=769825583More info:http://willoughbybaltic.squarespace.com/http://willoughbybaltic.squarespace.com/new/big-changes-at-wb.htmlTo sign up, go to:https://mgarniss.wufoo.com/forms/member-application/

Universal Nut Sheller

Today's feature is the awesome Universal Nut Sheller. Designed by Jock Brandis of the Full Belly Project for a women's coop in Mali, this tool dramatically increases peanut-shelling speed from 2 lbs per hour (hand-shelling) to 110 lbs per hour.  Since roughly half a billion people in the world rely on peanuts as a primary protein source, this nut sheller has the potential for serious impact. The machine is simple to make, relatively inexpensive, and can shell pecans, pine nuts, neem nuts, shea netus, Jatropha, and other nuts as well as peanuts.  Molds and metal parts can be ordered from the Full Belly Project. Check out the 2005 video introducing the machine to Uganda: Check it out, and get inspired.  What can you do to help people in developing countries?  We need more ideas, the simpler the better.

How to build a thatch roof for chicken coop from giant canes?

I have an unlimited supply of massively invasive canes (Arundo donax) growing on my property, and my chicken coop needs a roof.  Anyone have ideas on turning canes in their natural state into roofing material?   I will start just experimenting with weaving together lengths of cane, but some experienced advice would be very welcome. EDIT: Traditional thatching appears to involve attaching bundles to each other by essentially sewing them with wire or flexible blanches.  I'm thinking this is a specialized craft precisely because the techniques are not entirely improvisable. concerns:  weather proof materials (aside from canes, fixtures that will not rust/mold/decay) technique of attaching bundles to rafters? peak of the roof?

Bottled light in the Philipines

There's a novel, simple idea spreading in the Philipines - using bottles of water as skylights. The concept is staggeringly simple - slum dwellings are dark, and need light, even in the daytime. Though they have electricity, it is the most expensive in the area, so they can't afford to use powered lights. Instead, they use water. A two-litre bottle of water, with a little bleach to prevent algal growth, is set into a section of metal sheeting, which in turn is set into the roofs of dwellings, workshops, even chicken-coops.  The water-bottle refracts the light in all directions, instead of letting it shine through in a single beam, and provides as much illumination as a traditional 60W bulb. OK, so this is old news to some people, but it's new to me. For more information, have a look at the Litre of Light website, or just have a poke around Google and YouTube.

Arduino light controler based on preset time and light intensity

I want to build an Arduino based controller for my chicken coop that will turn on the lights at a prescribed time in the morning (while it's still dark outside), then turn them off during the day (using a photoresistor) and then turn them back on when the sun sets and then finally turn them off again at a prescribed time so my hens can sleep. I have an Excel file with the lighting cycle times that is specific to my global position that is designed to maximize egg production from my hens that I'd like to use to control the on and off times of the lights. Can anyone point me to specific recommendations on which arduino board to use, and how to set up the timer and photoresistor properly? Thanks!

3 Float/Reed Switches Controlling a 16 Pixel RGB LED Ring via UNO

Good evening, My latest project is for a level indicator on my chicken coops water supply.  I am using an Arduino UNO, 3 reed float switches and a 16 pixel RGB LED Ring (adafruit Neopixel).  I have the switches at 3 different positions in the water tank. I am wanting to light the RGB LED ring a different colour depending on which switch is closed.  The bottom one red, the middle orange and when at the top, green. I have the LED ring working.  I also can have the switch working on its own.  But not controlling the LED. I have no idea what to do next.  I am thinking that i need to get the switch turning the LEDs on.  Then I can start thinking about using all three at once. I am hoping someone can help?  It seems a simple task for the arduino to do but I am very new at this so I'm struggling a little bit. Thank you all in advance.

Light sensitive/remote pet door battery powered

Hi all i have scoured the site but cant seem to find a project that i need, and would therefore benefit from any help and advice on how to build an light sensitive automatic door opener for our chicken coop. it seems an obvious project to me,, hopefully one not too hard that i can do with your help. we have a barn thats too far away from the electricity, so it needs to be self powered by battery. i can look into trickle carging the battery by solar seperatley i am sure on the site. but, the wife is sick of having to go each night and shut the chucks in to keep them safe from the fox, and then open up every morning. we were wondering if we could use a standard light sensor you find on the cheap security lights at the DIY store, that would trigger some kind of motor or catch etc to slide or raise a door. then if possible, to do the opposite when the morning comes. if the LUX sensor is not possible, then maybe on a timer, or even posibly remote. i need help and advice on the whole thing, as i have no idea on what type of mote, (if i need a motor at all) i need, will it burn out if it has power all the time?, how to stop it? loads of questions i cant even think of support with your answer would be appreciated. thanks in advance

Year-to-Data, March 2014

Tl;dr: Check out this pie chart that shows the distribution of projects published in 2014 by category. The outer ring shows the channel within the category that had the highest volume of entries, along with the year to date project count. Do you ever wonder how the projects on Instructables are distributed across categories? I did, too. In a tenuous-at-best connection to the Pi Day Pie Contest, we made a pie chart showing where all the newly-published projects have been categorized since the start of 2014. That outside ring shows the most popular channels within the category, along with a project count for each. Some quick observations: (1) There isn’t as much food as I would have thought. It seems like people are posting food ALL THE TIME, but apparently the overall project volume is coming in via other channels. I guess we’re just getting a lot of good food entries that are being featured more often. The quality of authors’ food photography is getting very good, and the featuring team may be featuring projects under the influence of hunger. (2) Contests drive some (but not all) project builds. Since the start of the year, we’ve run paracord, organization, electronics, and crafting contests. And, wouldn’t you know it, those are the channels receiving the bulk of new projects. Even without a special contest, the Toys channel received an outsized number of projects, so we’ll see what happens later this year when we run a few contests around toys. (Pro-tip: Start stockpiling LEGO and KNEX pieces.) (3) Technology and Living make up just over half of the site’s new content. Sure, the robot has a strong preference for electronics projects, but we’re seeing a lot of great craft projects coming in as well. Either way, an army of hot-tool wielding* makers are creating some really cool stuff. (4) This community may be a little paranoid, but we’re prepared. Paracord and survival projects account for almost all of the outdoor projects we’ve seen so far this year. If I’m stuck in a rural farmhouse surrounded by zombies, I want some of you all right there with me. If you’re worried about the imminent collapse of civilization and are concerned that Instructables won't be around to help with the power out, you can buy a book of some of our best homesteading projects. You’ll be sitting pretty with a chicken coop and some rain barrels while everyone else gets punched over a can of soup. (Don't get punched over a can of soup.) (5) Did you notice anything interesting? Sound off in the comments. I've got some 3 month pro memberships to give away to insightful commenters. :D *or hot, tool-wielding authors.

How to use & wire relays, speed controllers, timers, micro switches, etc. with a DC motor.?

I would like to use a 110 volt, 1/2 hp (more or less), DC ( or AC ) reversing motor to move and close a horizontal, heavy (approx. 200 lbs.) fabric, thermal, curtain blanket and then to move and open back the blanket in a greenhouse. There are very expensive commercial greenhouse systems that exist to perform this task. Since I have a hobby greenhouse that is 30 ft. wide by 80 ft. long by 13 ft. tall, I need a much more affordable system. Horizontal wires or very large monofilament fishing line  (spaced 12" to 18" apart)  will run the length of the greenhouse at approximately the 8 ft. height. These wires or lines will be used to support the blanket and for it to slide on (the blanket will have grommets or similar devices used on a shower curtain to  keep the blanket running straight, etc. ) when mechanically closed and reopened. My idea is to use a DC or AC motor to perform this task with modifications to work in the greenhouse. The motor will consist of the 110 volt, 1/2 hp (more or less), DC or AC reversing motor, that will be connected to a small cable drum spool on the motor shaft, The motor  can be attached at one end wall of the greenhouse at 8 ft. high below or above the blanket and at the other end of the greenhouse also will have a cable drum spool with a pipe for rotation an be appropriately attached to the end wall. Attached to these 2 cable drum spools would be say 175 ft. ( 2 x 80 ft. plus initial amount on spool) of say 3/8 inch aircraft cable. The curtain blanket will have a say a 30 ft. long 1/2 inch or so horizontal metal bar or pipe attached to it on the leading edge. The aircraft cable will be attached to the blanket bar or pipe.The other end of the curtain blanket will be attached to the non motor end wall. As the motor turns the 2 cable drum spools  by wrapping and unwrapping the aircraft cable, the attached curtain blanket will be pulled the 80 ft. length of the greenhouse in each direction. What I want to accomplish is as follows:                                                                                                                                                        . 1. Be able to slowly, if possible, (say over 20 - 30 minutes) close (move forward) the blanket with the motor at a preset time in the evening and for the motor to stop when the blanket is fully pulled to the motor end of the 80 ft. greenhouse. 2. Be able to slowly, if possible, (say over 20 - 30 minutes) reopen (move backward) the blanket with the motor  at a preset time in the morning and for the motor to stop when the blanket is fully pulled back to the non motor end of the 80 ft. greenhouse. To accomplish this, this reversing DC or AC motor will need to reverse direction to reopen the blanket.                                                                                      3. The shaft of a motor will probably be too short to clamp a cable drum spool to. How do I attach the spools?                                                                                         4. What is best to use a DC or AC motor? I tried extensively to research on the internet how to accomplish the above, but everything described similar processes in vague and technical terms of using various types of electromechanical timers, electromechanical relays, limit switches, microcontrollers, MOSFET circuits, transistors, arduinos, bridge rectifiers, etc. I have no  knowledge of all of these electronic devices and am totally confused. However, I am pretty good at say basic home electrical wiring. The closest thing on the internet to what I am trying to accomplish is an automatic chicken coop door, but not enough specifics for my project. I need some very, specific steps, specific products and where they can be purchased to be able to accomplished this. What type of motor, types of electronic devices, etc. Also, since it appears I will need a timer, a speed controller, relays or limit switches, etc. how in the world to  wire these to the motor in laymen terms. Thanks so much for anyone that can help me!!!
