Step 2: Preparing the Paper Cutout

So, to start with, let's prepare the paper cutout.

The first image is the very simple paper pattern needed in this project. I have the paper pattern prepared by pepakura designer 3, a very handy software for preparing paper pattern. Although it's not a free soft, they offer a free viewer that can display and print their special .pdo files.

For this paper house, you can just download the .jpg file and have the pattern printed onto a thick A4 sheet (around 190 gsm). There are two house in one sheet just in case anything bad happens when you cut out the pattern.

Pay closer attention to the second photo and you will see that one window was not cut out. That window was left there in order to make the inside of the house darker, creating a better contrast when the light is up. Instructions on how the holes on the two roofs are cut out will be found in step 4. 

A dummy house shows how the lower layer of the roof is connected to the house's wall, as well as how the house is flattened. The missing upper roof will be glued onto the trapezoidal flat region of the lower roof later on but, don't do that now as we will still need to do some circuit connection on the roofs first. 

After having an idea of how the house is to be folded, you can now use the pen cutter to create the fold lines along the dotted lines by carefully cutting just a very thin surface layer of the thick paper. This scribing action will aid forming the house's shape as you pops it up from a flat pattern. Note that if you wanna do a mountain fold, you scribe the upper surface of the paper. and if you wanna do a valley fold, you scribe the back side of the paper.  In this model, only two lines on the lower roof and one line at the door need to be scribed underneath. All other lines are scribed on its upper surface.
Hehe, using a light to power a light; the first image was my very first thought. <br> <br>The next images show my next thoughts - if you could include a pummer circuit, your house would become an automatic solar-powered night-light.
Admirable hobby - undoing. Now, for an encore, turn the fan and generator toward each other for a typical perpeual motion (energy) machine. <br> <br>Wikipedia: East Anglia is a region of the United Kingdom of Great Britain and Northern Ireland at the level of NUTS 2 for statistical purposes. <br>NUTS 2?
No idea. We're rural, with relatively high unemployment. Maybe that's it?
Yes! What can possibly be more useless than a solar-powered torch? I find this project quite random too but I still pushed forward this for it simplicity. <br> <br>As for the circuit... Never though about this but, woot! Thanks! This will certainly add more usefulness to the whole idea of solar-powered lights. Let's see if i can design something with that. Thanks, man!
You're welcome.
<p>How quaint! I could get my team of estate agents to go and do this for our next team bonding day! It'll be a great project so thanks for sharing!</p>
To AmyLuthien<br>Not harsh at all...if he's going to do something it might as well be useable!!! And for YOUR information, the color can't be change!!!!!!!!<br>---------------------------------------<br>From: AmyLuthien<br>Date: Feb 19, 2013. 12:04 PM<br>Subject: https://www.instructables.com/id/Solar-powered-pop-up-paper-house/<br><br>Being a little harsh, don't you think? If you can't see it, change the color yourself, or put on your glasses, yeesh.<br>
Well, low lineweight can be a pain for those who are not used to doing papercraft.. Another .jpeg with higher lineweight is added just for you if you fail to see the lines. I am quite sure that photoimpact or programs alike can do the trick but it's not really that troublesome for me to make another version anyway, so, here you go. <br> <br>------------------------------- <br>FYI: <br>- The color can be changed, of course. So can the lineweight. <br>- I did my 5 houses with the original .jpeg file, so.... maybe it's the printer / ink?
No! Not the printer ink....everyone hasn't got YOUR amazing capabilities!!! <br>Doesn't really matter anyway.....
At first i thought it would be a house that literally pops up using motors or something. XD
Now that is a brilliant idea ! There are tiny electric motors about 5mm diameter, that run on a very tiny current, like those used in mobile phone vibrators.<br> <br> So now just devise a method whereby the motor shaft reels in a cotton thread that automatically pulls the house up into its final shape when it is taken out of the envelope. &nbsp; Easy enough. &nbsp;<br> <br> That will provide a really impressive effect !
Any chance that we could do that with a spring of some kind instead? I know that there exist some very weak springs...
Thinking quickly off the top of my head, possibly some kind of wound rubber band mechanism like in model planes, slowed down by smart grease for dramatic effect.<br> <br> Remember &quot;way back when we were kids&quot; the DIY tractor toy with a cotton reel, rubber band and pen ?<br> <br> So maybe a small card tube or matchbox, the rubber band going through and fixed at one end, with a matchstick through the other end, could be developed to create a small motor ?<br> <br> Perhaps the house is taken from the envelope as flat pack, and a tab is then pulled to activate the mechanism ?
Hmm, to me, it would make more sense to scribe on the INSIDE of the fold, since that's where the paper is going to bunch up when you make the fold. <br> <br>That's what I do when I do leather work, scribe the INSIDE of the fold so that the leather doesn't bunch up in that area when I make my folds. <br> <br>The way you say to do it seems a little counter-intuitive, to me. But leather, of course, is thicker than paper, so maybe it doesn't matter as much with the paper.
Thanks for pointing this out. I am not experienced in leather but I assume &quot;scribing&quot; refers to some kind of material removal in leather terms, does it? Here, by scribing, I am referring to just cutting apart a very thin layer of a sheet. Then, when folded, the outer layer, supposeingly in tension due to fold, will burst out to release such stress instead before the inner layer bunches up. <br> <br>I suspect that for leather, a clean surface is much desirable. Leaving a burst outer surface of a fold is very much not desired and material removal of some kind might be performed on the inner layer instead, I assume. But for white paper, bursting out is almost invisible, yet easier to perform. So, for paper, I tend to cut open the outer layer of a fold to prevent bunching. <br> <br>Hope this addresses your concern.
I'm curious about the pop-upping feature. Can you show that in a pic or -even better- a video? Cool project! <br> <br>Y.
Added the 7th step for the pop-upping feature but, again, I suggest you to go for either pop-upping or just a paper house since the LED might crush the solar panel if you flatten the house too hard.
Thanks, looks nice! I see how the LED and the solar panel might clash with each other. But the (un)folding of the house looks pretty cool :-)
Er... Yes of course. I got some extra cutouts in my workplace. Maybe I can take some more photos / video of the pop-up version of this when I am back to work on the 14th.
So I was thinking you could make a slightly bigger house and embed the guts of the really small solar lawn lights in the roof so it lights up at night. I think they are $1.50 at walmart and they have a stubby AA battery in it. I would do it but I have another flashlight hack ahead of it on my to do list. It&rsquo;s all yours this week.
I guess it's not hard to tweak the design a bit and go with an on-the-shelf panel. Thickened wall made out of cardboard or plastic board of some kind will also allow small LEDs to embed into and the house could lie completely flat. (but now the house is even thicker just by its wall thickness <br> <br>I like the circuit that allows the house to light up at night a lot though. Will certainly go for it when time allows.
Oh,wow. 1,455 views and 7 favorites on first day. Great job!
It's my first time posting an entry onto instructables or any sites of its kind. To be honest, this view rate is a bit... scary. Wasn't expecting all this at all...
Great. Now its 5,546 views and 27 favorites. Isn't this a new record?
It's my personal new record : p
Hello Alvin, <br> <br>What can I say. <br> <br>Nice job. I can just see these sitting on the shelf at Christmas at Radio Shack as stocking stuffers. I hope this gets featured. <br> <br>Lux
Nice work and photogrphy. Your intro (and step 6) photo is awesome.
Thanks! (special thanks to the iPad mini I used to take those photos as well
That's a simple and nice paper house. <br>I saw that it is your first project so I wanna say Welcome to Instructables.
Thanks for your warm welcome : )
Cute little house!
