o sensor Shield V5.0 - 2 standard servos (plugged into pins 9 and 10 in the sensor shield) - 7.5V wall power supply - USB cable to computer
I'm running Rhino SR 8 on a 32 bit Windows Vista machine I have Version 0.9.0014 of grasshopper (the latest) and Firefly_Build_1.0067 I have flashed my Arduino board with the latest firefly firmata (updated September 10th, 2012)
I have checked that I am using the "MEGA write" box I have got the right bits going to the right pins and I have checked that they all have "servo" ticked instead of "digital" or "pwm"
My servos and board work perfectly well with the normal Arduino software, but just not any longer with firefly since my computer was switched off.
The port shows correctly as COM 4 and opens fine.
When I move the slider to control the servos, the TX light is on and the RX light flashes, but no servos move... (everything works with the sweep example in arduino though, so I have eliminated power and wiring issues)...
Any ideas what might be the problem?
I've tried re-installing, switching off and on many times, changing cables, trying a different board (also doesn't work any more with the duemilanove), trying all pins on the shield, trying one servo without the shield, trying one servo with the shield, lots of googling, lots of searching forums, unblocking the firefly installation files in explorer, lots of things... I'm all out of ideas... And very confused as it was working just a few days ago... Am I just missing something really obvious or could there be an issue with the software at my end?…
edefining the axis variables, logarithmic scales, display thresholds, better marking management - or at least add contrast!
Hey Fred,
thanks for the feedback! This is a basic version, and personally I used a custom component to read and parse the history files from the canvas to be able to e.g. scroll through generations and solutions or display more solutions at once (via pathes, mostly requires modification of the initial setup) ...
but you are right. I would love to bring the solution's navigation directly into the rhino viewport but I think that would be a major hack .. unless you can give me a hint how to do that. the displaying and user-preference-handling are besides a re-entrant history, some more algorithms and parallelization the next things to tackle, but display is definitely one of the easiest, so ... soon! work will begin in january i guess, since the project then starts i hope - but it will start for sure.

an external test suite.
We have a lot of parameters we want to test with, so doing so in Rhino is cumbersome.
To this end, we've experimenting to run Rhino/Grasshopper with a number of ways:
- 1) Using the COM interface, to create Rhino, load grasshopper then run tests
- 2) Exposing Rh/Gh internals using WCF via a Rhino command, which starts off WCF, then run tests
- 3) Exposing Rhino/Grasshopper internals using .Net remoting, again via a Rhino command
We've tried -1) that seems to be a dead end, limited access to Rh/Gh
We've tried -2) that works but raises an error in the WCF server stating that RhinoCommon is not available (see attached image). I've tried copying dll's from the Rhino installation to the running wcf directory, but that does not help.
Todo -3) We've still got to try this method.
I've googled similar entries in the forums:
http://www.grasshopper3d.com/forum/topics/how-can-i-use-grasshoper-externally
http://developer.rhino3d.com/api/rhinoscript/introduction/external_access.htm
Does anyone know why -2) wcf fails or if .net remoting will work successfully.
Or indeed if there are other options to address our use case?
Many thanks,

the space that you are designing and your design intent. Just think about an atrium vs a museum. And now think of the atrium in two different climate zones. As a [lighting] designer you make the decision on how do you want the space to be, how the climate is and then try to take advantage of skylight and/or direct sunlight to achieve your design goals.
2. Yes. There is a watchTheSky component next to sky types which let you visualize the sky. There is also an example file that you can check.
3. This one again depends on your model. For your model I would suggest a minimum number of 4 for your final analysis. -ab is only one of the parameters. Check this slides by John Mardaljevic if you want to have a better understanding of radiance parameters and their effect on the results.
I also added the link to "Tutorial on the Use of Daysim Simulations for Sustainable Design" by Christoph Reinhart to teaching materials. I encourage you to at least read chapters 1 and 2 of the tutorial. Check pages 25 and 27 have two examples about selecting the parameters.
Great questions. Keep them coming.

evel in which each final branch contains a list of one number from each list in all its variations with the other two lists.
12
AB
xy
Becomes eight possible combinations:
1Ax
1Ay
1Bx
1By
2Ax
2Ay
2Bx
2By
Either I could immediately break into 8 branches or branch twice from 2 items to 4 items then from those 4 items to 8 final items. I keep trying grafting with all manner of tree components and *never* obtain a simple dual branching fractal tree structure. I barely even need a tree actually, but I'd prefer each final branch to contain a list I can pull each final value individual value out of rather than dealing with string extraction. This is all to eventually plug all these variations into a parametric mesh model that now uses three sliders, and Python script also to bake them all as OBJ files.
Crucially I also need to obtain the numbers to use as part of my multiply exported OBJ files. I can so far only get a single range to export as a series of OBJ files automatically but not the whole three list array of them.

ace when I start running Galapagos/Octopus (below is "room orientation optimization" shared at http://hydrashare.github.io/hydra/viewer?owner=mostaphaRoudsari&fork=hydra_1&id=Room_Orientation_Optimization&slide=0&scale=1&offset=0,0) It may take quite some time to see some results. That's fine for the above simulation. But my real challenge is, when I am going to optimize room dimension with respect to ASE and sDA calculations, either Galapagos or Octopus goes wildly and never come up with a solution. I believe the time-consuming calculation, especially sDA with higher -ab numbers, trigger the lag a lot? Any suggestion/trick to improve it?
Most importantly, based on your experience, for example to optimize window/exterior shades sizes and achieve ASE<10% and sDA>55% (LEED v.4 requirements), Octopus (due to its capacity of multiple objectives) is the only choice? Any other approaches within grasshopper?
Many thank!

used of 180 being for the northern hemisphere and 0 for the southern hemisphere.For the optimal tilt, to my knowledge, they are mostly based on correcting location's latitude through a single formula.TOF component is more sophisticated. It essentially replicates the Solmetric's Annual Insolation Lookup tool.What it does is that it creates a grid of points. Each point represents the calculated annual insolation on the surface (PV module, SWH collector, facade, any kind of surface) for a single tilt and azimuth angle.Each point is then elevated according to the annual insolation values. The mesh is created from that grid of points. The portion of the mesh which is the highest, represents the optimal tilt and azimuth angles. So the higher your "precision_" input is, the more points in a mesh you'll have - thus the more precise final optimal tilt and azimuth will be.For the diffuse component of the annual incident solar radiation for each point the Perez 1990 modified model is used. Direct is from classical cosine law, and Ground reflected component from Liu and Jordan (1963).So TOF component calculates the optimal tilt and azimuth based on annual incident solar radiation, not AC energy....…
giornata inaugurale sarà dedicata alla free-lecture introduttiva finalizzata alla realizzazione di un modello d'architettura complesso attraverso l'utilizzo di comandi e tecniche avanzate di rappresentazione con Grasshopper (plug-in parametrica di Rhinoceros) e 3dsMax. Sarà illustrato inoltre il potenziale di V-ray per 3dsMax realizzando un rendering concettuale. Durante il mini-corso dell' openDAY verranno mostrate le caratteristiche e le potenzialità degli strumenti per far luce sui nuovi valori assunti dalla modellazione 3D. La modellazione 3D sta interessando un pubblico sempre più vasto inserendosi in una nuova fase di ampia disponibilità per conoscenze, software, hardware di prototipazione e modelli. Pur mantenendo tutti i suoi valori già noti la questione si è talmente ampliata fino ad interessare norme giuridiche (diritti sui modelli ,concorrenza con offerte di servizi apparentemente simili, informazioni deformate e onfusione nei media) Makers University[http://www.makersuniversity.com], in collaborazione con parametricart, vi propone un punto di vista ampio e sintetico su queste tematiche.
Al termine della free-lecture, sarà illustrata l'offerta formativa [CLICCA QUI] di parametricart riferita ai corsi che si terranno nei mesi di Gennaio e Febbraio 2013 inseriti all'interno della più ampia programmazione della Makers University. SONO PREVISTE TARIFFE PROMOZIONALI PER COLORO CHE SI ISCRIVERANNO AI CORSI durante l'OpenDAY.
La lezione e la presentazione si terranno nel nuovo spazio co-working il PEDONE.

la corretta comprensione del software che di livello specialistico per un confronto diretto con alcuni aspetti fondamentali dell’ architettura e del design.
Attraverso l'utilizzo di Grasshopper rivoluzionaria plug-in di Rhinoceros, si insegneranno nuove tecniche di modellazione parametrica.
Grasshopper, permette di esprimere al massimo le qualità e le potenzialità della modellazione Nurbs abbandonando in parte l'interfaccia classica di Rhinoceros. Quest'ultimo infatti viene sostituito da un menù a tendine dove vengono collezionati nodi utili alla composizione di algoritmi risolutivi.
La plug-in Grasshopper, dimostra come il linguaggio del computer stia diventando un reale strumento progettuale.
Il corso si svolgerà nei seguenti giorni: Sabato 26 Ottobre dalle ore 10.00 alle ore 19.00 Domenica 27 Ottobre dalle ore 10.00 alle ore 19.00 Scadenza preiscrizione per Grasshopper: 23/10
Contenuti
Nella prima parte del corso attraverso degli esercizi base si insegneranno i metodi di esplicitazione degli algoritmi generativi. In queste ore di lezione si illustreranno, attraverso fasi operative, i seguenti argomenti:
Suddivisione degli algoritmi in parametri e componenti;
Tipologie di dati comptiili con Grasshopper e loro combinazione creando definizioni minime;
Funzioni matematiche e logiche;
Data flow, liste e filtri di esclusione;
