Step 7: Arrange compasses

If the table were a square or rectangle I would have arranged the compasses in a grid, but since it was a circle (to match the circular form of the compasses themselves), I had to come up with other arrangement options.  After fiddling around with them for a short while I was able to find something that worked well - concentric circles.

Arrange the compasses as tightly as possible working from the outside in, getting the final few in place takes a bit of a massaging, but once they all go down, it's a nice symmetrical tight fit that can adjust to whatever size circular table that you have.

<p>This Instructable clearly has direction!</p>
Awesome Ible.....
What about adding wheels so you can turn it and all the compass arrows turn
<p>Very neat project! I love the simple and subdued look of the table. Have you considered putting small magnets in the bases of the coasters? It could be a fun way to visualize magnetic field lines! </p>
Check out step 9 - the coasters have rare earth magnets embedded right into the bottoms.<br /><br />Thanks for the feedback!
<p>Finally finished my version! Thanks for the inspiration.</p>
oh wow! That's so cool
Interesting project, thanks for posting it. I originally thought it would be a table with a homemade compass under it, but now I see it is 500 compasses lol. Have you tried making your own large compass?
Here is my version I made for the Vancouver Maker Faire 2012 <br>http://www.abluestar.com/blog/wp-content/uploads/2012/08/IMG_4790.jpg <br>
That looks awesome! Did you modify an exiting glass top coffee table? I'm so glad that you decided to replicate this project and post a picture of the finished tab. Seriously - nice job.
This is the perfect idea for my woodworking class! Thanks!
Neat ! &acirc;€&brvbar; <br>I also like the music playing on your video : very 50's !!!&acirc;€&brvbar; cool.
This is fantastic Noah, great video too!
I saw this on a TED talk about the importance of sabbaticals, I wonder, are you that guy or did you both come up with the same idea ? I heard about an interesting phenomenon of <a href="http://en.wikipedia.org/wiki/Multiple_discovery">Multiple Discoveries</a> in <a href="http://www.youtube.com/watch?v=nR-klTa1y54">a recent talk by David Wilcock </a>
:D awesome! at first i thought it was a giant compass as a table :P
Great Job!!!!
This is just outstanding. Top marks for thinking - as wiggins said below - hilariously big. I'm a total sucker for Epic Scale Silliness combined with good craftsmanship, so this sir, is a WIN XD
Hilarious. Well done.
Dude, that's a lot of compasses! You'll never get lost!
Fantastic! We're going to make one the nature center where I work, to help teach kids about the earth's poles, and orienteering, etc. Also, it's just a great toy for kids to play with!
aaaaand: we did!
Nice table! Looks good. <br>After calculating the cost of the compasses, I can totally see why you arranged them that way
That is FABULOUS! Great use of the 'Ible.
I agree with Muller....Want, want, want, want!
mate that is totally AWSOME!!!!
Nice project. Where can you find cheap glass?
Ok thats just plain cool. I am going to have to do one of these one day.<br><br>as for sources of compasses? go a little nuts and even smaller compasses<br><br>http://www.dealextreme.com/details.dx/sku.4519<br><br>$2.54 shipped for 20 of them. figure what? 1500 of them for this project? $190<br><br>would also be cool to use different compasses IE one in the center much larger or spaces around to form a nice pattern<br><br>here are some of the cooler ones I found.<br><br>http://www.dealextreme.com/details.dx/sku.35475<br>http://www.dealextreme.com/details.dx/sku.11880<br>http://www.dealextreme.com/details.dx/sku.11896 (this one is big 6.3&quot;)<br>http://www.dealextreme.com/details.dx/sku.2834<br><br>More expensive but much larger and &quot;nicer&quot; for a larger version of this table?<br>http://www.rinovelty.com/index.cfm/fuseaction/products.detail/item/AMCOMPA/18pc_bulk_compass_set<br><br>18 of them for $26 just rip the compass itself out.<br><br>These are one of my favorites more money ($1 a pop but also much larger at 2&quot;)<br>http://cgi.ebay.com/60X-New-Plastic-Compass-Key-Rings-Wholesale-/380302127478?pt=LH_DefaultDomain_15&amp;hash=item588bc5f176<br><br>best deal (same ones used here)<br><br>http://cgi.ebay.com/Wholesale-Lot-20mm-Small-Mini-Compasses-4-survival-kit-/130461497769?pt=LH_DefaultDomain_0&amp;hash=item1e601c79a9<br><br>48 for $15 so 500 would cost about $165 you might be able to wheel and deal a better price ordering that many though.
144 for $8&nbsp; on <a href="http://www.orientaltrading.com/ui/browse/processRequest.do?demandPrefix=12&sku=39/37&mode=Searching&erec=1&D=mini+compas&Ntx=mode%2bmatchallpartial&Ntk=all&requestURI=processProductsCatalog&N=0&y=0&Ntt=mini+compas&Dx=mode%2bmatchallpartial&x=0&sd=Mini+Compasses">Oriental Trading</a>
you might find your project in a bit wider perspective in <a href="http://www.dunneandraby.co.uk/content/projects/70/0 ">dunne &amp; rabys placebo project</a> from 2001 which includes amongst others a compass table.<br> <br>
I would love to do this project... But unfortunately I dont have the time (or patience) to do it... =(
That's really cool. Just when I thought I couldn't get any more lost... XD
So all together how much total money was used to make this project?
Not what i thought it was, but still clever! Being old and feeble, I thought it was a table where the top was a compass and pointed North via the coasters. Not as much fun as Noah's table, but just one compass instead of a gazillion--that is how many compasses are needed for this, isn't it?
how much did all those cumpases cost???
do the math 1 for 20c, he need 500, 500x0.2 or 1/5 of 500 is 100. it cost somewhere around 100 bucks.
ouch thats really expensiv for a table
&nbsp;lol awesome video, i bet he ALWAYS knows were hes going :) awesome &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;North East South West = Never Eat Soggy Waffles, but thanks to ur post, i can eat soggy waffles and STILL KNOW WHERE IM GOING!!! isnt that AWESOME?!?!!?
North, East, South, West<br /> Never eat shredded wheat.<br /> Our teacher taught us that in school, and I still use it to this day lol.
NEWS stands for north, east, west, south .

Oriental trading company sells those little compasses for $7.95 for 144! http://www.orientaltrading.com/ui/browse/processRequest.do?demandPrefix=12&amp;sku=39/37&amp;mode=Searching&amp;erec=2&amp;D=compasses&amp;Ntt=compasses&amp;Ntk=all&amp;Dx=mode%2bmatchallpartial&amp;Ntx=mode%2bmatchallpartial&amp;N=0&amp;requestURI=processProductsCatalog&amp;sd=Mini+Compasses
how did you mesure the table to that when you put in the magnets they lined up perfectly with out leaving gaps<br />
You could just measure the diameter of one compass, and make sure the table has a multiple of that diameter.
&nbsp;i vote you mount large magnets in the coasters!
Now make the whole table a single big compass. LOL Good work.<br />
That would be pretty sweet.&nbsp; <br /> <br /> I wonder what the limiting factor is on a giant compass.&nbsp; <br /> <br /> The friction on the rotation point, the strength of the earth's magnetic pull, the weight of the needle itself?&nbsp; <br /> <br /> Anyone have any experience with very large scale compasses?<br /> <br />
The big limiter is friction - even the compasses you used are balanced on a pin-point (if the table ever gets a big whack, some will come off their pins - be careful).<br /> <br /> You could try the ancient floating-needle trick - make a huge compass rose on a sheet of light foam, float it on a pool under a sheet of glass.<br /> <br /> At the N&nbsp;&amp; S points of the rose, inset magnets arranged to act as the ends of a bar-magnet.<br /> <br /> What would be the point, though?&nbsp; Once you place the table, it will turn, settle, and never move again.<br /> <br /> Instead, I would randomly set neodymium magnets into the sheet of foam, with randomly-facing poles (you can get cubic magnets), so that the foam disc with twitch and turn as magnetic objects are placed on the surface.<br />
&nbsp;the foam would be drawn to one side of the pool and not rotate, ok last comment here. I made a few little mistakes in the descriptions of the huge compasses i have made<span class="Apple-style-span" style="color: rgb(61,61,61);">, the best giant compasses I have made used rare earth disc magnets aligned along the north south axis, they were balanced and hung by a filament, the simplest of which consisted of a single 2&quot; diameter 1&quot; thick neodymium iron boron disk attached to a fine thread with electrical tape and hung from the ceiling, I have used smaller safer : ) disks stuck in the ends of a length of rigid tubing and suspended similarly, various configurations and materials all definitely did some strange things besides aligning themselves north/ south, the strongest were perturbed by passing cars and most of the others responded in unison even when separated a great distance e.g. 40 feet or more, to periodic oscillations that, I have no concrete explanation for but, I think may have something to do with the field produced by the electrical system in the house&nbsp;. &nbsp;</span>
how long did it take you to collect 500 identical compasses? :Plol
