In this case we see a geometrically approach, which doesn’t works efficient, because it required knowing how they behaviors together before, and I think it is not the ‘really behaves’.
To make the structure ‘really behaves’ I tried use kangaroo and the result works very well! As you can see I simply give the 2-set reverse UForce, and then they start to rotate until they found their equilibrium. That means 90 degree rotation. I was wondering what we can do to make a endless-rotation. I am mean 360 degree or more like this:
https://www.youtube.com/watch?v=4owFczeqqMQ
By the way, I try to give supports which allow a horizontal movement only (Just curious how we could keep the anchor-movement horizontally and in the same layer, for example like usual supports for compression ring…). I use the AnchorXYZ, but Kangaroo-Engine seems don’t accept its output.
So maybe some one knows a better solution?

problem later) to fit more shapes that are otherwise won't fit in.
On the example below horizontal rectangle couldn't fit in but its rotated analog could and thus was placed in.
Later, when placed shapes are used to generate frames, because of this rotation, the position of the starting points changes and because of the approach I use to generate the frames some angle values are attached to the wrong corners, this brakes the frame shape and looks like this (on the left the frame of sick shape and on the right the frame of the healthy shape):
Again, this happens because the angle values are assigned to the specific corners (points) and previously rotated shapes get these all messed up:
Easy fix, don't rotate the shapes, problem is, I've already baked a good number of them for later use. I'd like to avoid regeneration because it takes a lot of time and without rotation I constrict the algorithm even more.
Better fix, use a different approach, this is where I'd like to hear suggestions and kicks in a right direction. Please take a look at my definition. It works but I have a feeling like giving an amputee a job of sweeping the floor.

ns. but first allow me to explain what i'm trying to do: i have a serial device i want to talk to, but i have to do it using some sort of handshaking. for instance, when i send a command/data, i need to wait for an appropriate response before sending another. i have used andy payne's general serial components from firefly, but i don't think they'll work for what i want to do, and in general, i want to know how to do this from scratch. i'm using the pyserial library to do the comm, and i can get it to work within one script. here's an example of a working (mostly) port open/close script (x=input param for baud, y=input param for port name, z=boolean input param for open/close):
import serialmyPort=serial.Serial()myPort.baudrate = xmyPort.port = yif z == True: try: myPort.open() except: print "Something went wrong. Cannot open port." if myPort.isOpen() == True: print myPort.name + " is open" if z != True: try: myPort.close() except: print "Something went wrong. Cannot close port." if myPort.isOpen != True: print myPort.name + " is closed"
this all works well and good. here are my questions:
1) I can open the port and then close it. however, if i try to re-open it, i get an access denied error. it seems rhino is holding the port open, as i have to re-start rhino to get it working again. i read through the discussions and didn't see any definitive answers to this problem. any advice?
2) I'd like to share this port with other components (or at least break up the functions of opening/closing the port and read/write, not unlike how the firefly components are organized), but i have no idea how to share an object instance between components. i did see that there is a sticky dict and tried to add myPort to it, but i kept getting errors in the other component when i try to use the object's methods. for instance:
Component 1 Script:
import serial
import scriptcontext
myPort=serial.Serial("COM4", 9600)
scriptcontext.sticky['myPort']=myPort
Component 2 Script:
import serial
import scriptcontext
myPort=scriptcontext.sticky['myPort']
print myPort.read()
but i get messages like:
Runtime error (MissingMemberException): 'Serial' object has no attribute '_port_handle'
any assistance would be greatly appreciated!!

t. So here we go!
1. Honeybee is brown and not yellow [stupid!]...
As you probably remember Honeybee logo was initially yellow because of my ignorance about Honeybees. With the help of our Honeybee expert, Michalina, now the color is corrected. I promised her to update everyone about this. Below are photos of her working on the honeybee logo and the results of her study.
If you think I'm exaggerating by calling her a honeybee expert you better watch this video:
Thank you Michalina for the great work! :). I corrected the colors. No yellow anymore. The only yellow arrows represent sun rays and not the honeybee!
2. Yellow or brown, W[here]TH Honeybee is?
I know. It has been a long time after I posted the initial video and it is not fun at all to wait for a long time. Here is the good news. If you are following the Facebook page you probably now that the Daylighting components are almost ready.
Couple of friends from Grasshopper community and RADIANCE community has been helping me with testing/debugging the components. I still think/hope to release the daylighting components at some point in January before Ladybug gets one year old.
There have been multiple changes. I finally feel that the current version of Honeybee is simple enough for non-expert users to start running initial studies and flexible enough for advanced users to run advanced studies. I will post a video soon and walk you through different components.
I think I still need more time to modify the energy simulation components so they are not going to be part of the next release. Unfortunately, there are so many ways to set up and run a wrong energy simulation and I really don’t want to add one new GIGO app to the world of simulation. We already have enough of that. Moreover I’m still not quite happy with the workflow. Please bear with me for few more months and then we can all celebrate!
I recently tested the idea of connecting Grasshopper to OpenStudio by using OpenStudio API successfully. If nothing else, I really want to release the EnergyPlus components so I can concentrate on Grasshopper > OpenStudio development which I personally think is the best approach.
3. What about wind analysis?
I have been asked multiple times that if Ladybug will have a component for wind study. The short answer is YES! I have been working with EFRI-PULSE project during the last year to develop a free and open source web-based CFD simulation platform for outdoor analysis.
We had a very good progress so far and our rockstar Stefan recently presented the results of the work at the American Physical Society’s 66th annual DFD meeting and the results looks pretty convincing in comparison to measured data. Here is an image from the presentation. All the credits go to Stefan Gracik and EFRI-PULSE project.
The project will go live at some point next year and after that I will release the Butterfly which will let you prepare the model for the CFD simulation and send it to EFRI-PULSE project. I haven’t tried to run the simulations locally yet but I’m considering that as a further development. Here is how the component and the logo looks like right now.
4. Teaching resources
It has been almost 11 months from the first public release of Ladybug. I know that I didn't do a good job in providing enough tutorials/teaching materials and I know that I won’t be able to put something comprehensive together soon.
Fortunately, ladybug has been flying in multiple schools during the last year. Several design, engineering and consultant firms are using it and it has been thought in several workshops. As I checked with multiple of you, almost everyone told me that they will be happy to share their teaching materials; hence I started the teaching resources page. Please share your materials on the page. They can be in any format and any language. Thanks in advance!
I hope you enjoyed/are enjoying/will enjoy the longest night of the year. Happy Yalda!
Cheers,

creating the structural frame, finding the endpoints, linking these endpoints with curves and afterwards lofting the surfaces between the curves.
The results were quite nice, however, the procedure is very time consuming and inefficient. There is just too much copy-pasting involved.
(see attached file: "Old Attempts.zip" )
Mesh relaxation:
I have later on used Daniel Piker's tutorials on Mesh Relaxation and realized that this might be the way to go.
The link to these online tutorials on wewanttolearn.net is:
https://wewanttolearn.wordpress.com/2011/10/22/mesh-relaxation-kangaroo-tutorial/
His tutorials, however, only deal with mesh boxes which are ideal cubes. He then joins them together in various directions, but it is under 90 degrees angle.
( see attached file: "Daniel Pikers Examples" )
What I would like to achieve:
I want my bridges to go in all directions and angles, not just under 90 degree angle.
Ideally I would like to make a square (polygon) follow a curve (which moves in all axis) at certain number of division points. I would then loft these squares into a mesh and use that shape as a mesh box. I would later use this mesh box and relax it the same way as Daniel Piker used the cubes in his tutorial. The anchor points are only the vertices of the squares which create the lofted mesh box.
( see attached file: "New Attempts" )
As you can see below this procedure works even if the curve is moving in all directions not only along xy axis. There are, however, many problems connected to it.
The problem:
Despite all the effort I cannot seem to come up with a design where I would be able to draw a random curve which would be the guideline for my mesh box and then apply this box to one definition in order to relax the mesh and create the shape that I want. Without this I am again forced into a lot of copy pasting as the final mesh box is made out of several sections.
Also is there any way I could make the final resulting mesh a bit smoother? Increasing the number of mesh faces is probably the only way, right?
Thank you guys so much for any potential help.
All best,
Luka

ur setup. Can you say what sensor you are using? Are you using an Arduino to write this ascii information to the serial port? If so, there may be some formatting code for the string that you'll need to do to get the Read component to function properly. I see that you were able to open the port and Start reading... so my first thought is that the data is formatted correctly....
All of the read components look for a specific character (in this case two characters) to indicate when it has reached the end of the line being read and should spit out the data. In this case, Firefly uses the Carriage Return (\r) and Line Feed (\n) to know when it has reached the end of the line. In arduino, these are automatically added to any line if you use the Serial.println("blah, blah, blah"); command. Notice, this is different from the Serial.print("nothing to see here"); command. This doesn't mean that you can't still use the regular print command... it's just you need to use the println command to indicate when you've reached the end of the line. Let's take a look at a simple example.
void setup() { Serial.begin(9600);}void loop() { int sensorValue = analogRead(A0); Serial.print("The value of the sensor is: "); Serial.println(sensorValue);
delay(20); // important to wait some small time so you aren't sending just a ton of info over to GH which will cause it to crash :(
}
The first print statement prints a string to the serial port... and the next one adds the current sensor value... and THEN adds the carriage return and line feed to start a new line. The nice thing about using these together is that you can concatenate any type of data you want. If you were to upload this sketch, you should see a sentence being printed to the serial port that says "The value of the sensor is: 512". I made up the number, but you get the idea. Notice, I also had to include a delay function. You don't always need this (there are other ways to go about this) but the important thing to note is that the loop cycle on the Arduino can run really fast. I mean... really fast. So, you wont want to send so much data over to GH, because this could flood the string buffer in the Read component and cause it to crash (eventually). It's a good idea to add some small time interval just to slow it down a bit. I should say that I've optimized the refresh rate in the next release so it's significantly faster... so hopefully this wont be as big of a problem... but hopefully that helps some.
Now... Why are you writing data to a sensor? Sensors by default are considered inputs... so I'm quite confused as to why you would want to send data back (if you are... then you need some way to handle the string data being sent from GH... this is the whole reason we built the Firefly firmata... it sets up the two-way protocol so you don't have to deal with all of that mess... If you're going to read and write, you're better off just uploading the firmata and using the Uno Read and Write components). Also, I'm not very familiar with the Hyperterm or Advanced Serial Port Terminal... but I will say that could get COM conflicts if you're trying to open the port with different tools. Anyway, I hope some of this helps you get up and running.
Cheers,
Andy

of a hack to push it to an android device, and you can't use labels, which is a very bad point!
...
I won't buy an Iphone!
The other is Control OSC. It looks rougher, but it has a lot of advantages to me.
+ Game of Life included!
+ you can use and update labels :))
+ Has a nice muti touch widget unfeatured in touch osc
+ You can script the interface using java script manipulation in gh, stream it to your dropbox and update in one "tap", as follows
Does anyone have experience with scripting interfaces for this software? I'm stuck already. I know nothing of java script to begin with. As you can see I managed to format the labels but the osc message I could not find a way, it stays untouched.
Just in case someone knows better, here are my "objects" (I said that right?). The userXXX are replaced in GH.
{ "name":"userName", "type":"Slider", "x":(xPadding + .11), "y": yPadding, "width":.82, "height":.082, "color":"userColor", "min":userMin, "max":userMax, "ontouchmove" : "var roundedvalue = this.value.toFixed(userFix); LbluserName2.changeValue(roundedvalue)", "onvaluechange": "oscManager.sendOSC('/userName', 'f', this.value.toFixed(userFix))",},{ "name":"LbluserName1", "type":"Label", "x":xPadding, "y": yPadding, "width":.1, "height":.05, "color":"userColor", "value": "userName"},{ "name":"LbluserName2", "type":"Label", "x":xPadding, "y": (yPadding + 0.05), "width":.1, "height":.05, "address":"/userName", "color":"userColor", "value": 0},…
to host the annual parade of Samba Schools during the Carnival festival. For the remaining 361 days of the year it stands empty and desolate as a massive dividing wall within its degraded urban context. Renovated in 2012 and now the future site for the 2016 Olympic marathon finish line and archery events, the Sambadromo is receiving renewed international attention, but it drastically needs to accommodate new types of programme and improve its connection with its surrounding context. AAVS Rio de Janeiro will explore ways to intervene within and transform the Sambadromo, with a potential focus on the VIP and Press Rooms ‘camarotes’, which were originally designed to house classrooms when Carnival was not taking place, and are now the site for over-commercialized, under-designed temporary installations during Carnival, and abandoned throughout the rest of the year. Teaching team:The teaching team will be led by Elena Manferdini, from Atelier Manferdini (www.ateliermanferdini.com), to teach and use advanced digital design and fabrication to generate iterative transformations in the creation of new micro-infrastructures. Computational and fabrication skills: The workshop will teach advanced computational design skills. A series of physical models will be built using digital fabrication techniques, such as laser-cutting and rapid-prototyping, that will be taught during the workshop. No previous digital or fabrication experience is needed.
