GRASHOOPER A tool for generative modeling that allows you to create parametric models, parametric architecture in Rhinoceros 3D environment Interface plug-in The process of modeling in Grasshopper is the creation of an algorithm. At Grasshopper the interface, it means that we write the script text, and we connect years and we set some options. The algorithm consists of the initial data or parameters and the sequence of actions with them. As a result, geometry and related information (volumes, areas, markings, sizes) are generated. With the help of noses and parameters, geometry can be changed, you need to change the value of one year and make a shift, and all geometry will be rebuilt. Thus, in Grasshopper we create not only a model, but the logic of its behavior. Once you have created a script, you can reuse it and edit it further. In this model, the task was to build a geometry dependent on the point of attraction. Attractors in a rectangular node You can add an attractor to a suitable site in three ways: drag the element onto the agent chart or use the drawing mode, in which case the graphics editor will select the shapes suitable for setting the attractor; or select the node and add the attractors by clicking the Attractors button … in the node properties. The created geometry is easily changed by changing the parameters of the code components.
Introduction: This is about what it takes to get things done. Every project has a life cycle and the hardest of all the stages is the materialization – the manifestation of the physical project. This is the true challenge and test of a makers worth. Working on the realization of great ideas requires tools and manpower. In this instance both were equal to the task of realizing Elena and Ivan Mitrofanova’s project “Green Spark” Tools:

Introduction: BCI feedback induces cortical plasticity, a basis for prompting behavioral changes, improving cognitive performance, ethics aside – neuromarketing … and on the surface test your concentration skills through gamification. In about a decade or so, interfaces like mindwave could be the obsolete versions of advanced wetware.

Test of user interface – Mindwave

The market for neural interfaces is relatively young and the relevant technologies are still growing. At the moment these user interfaces look more like prototypes  rather than the final product. It is envisaged that the technologies would evolve into more user friendly interfaces which would seamlessly interface man with virtually any networked platform. The potential for these items is colossal, however for now we have to be satisfied with the clumsy software on the phone which cannot really performs quite as seamlessly as it should.

Challenges: Create a tile with your own drawing using cnc machine

IDEA


  The idea was to create a panel of Soviet hruschovka with its typical inhabitants.
 

DESIGN PROJECT

In the beginning, the base unit with clear dimensions in the sketchpUp was designed, exported to 3dsMax, where entourage and staffing – curtains, grandfather, cat and flower were added. Later, the model was exported to stl.

PREPARING WAY

To create a tile it was necessary to prepare a path for bits in the CNC machine. The path consists of two parts: draft and finish. Rough removes large masses, has a big step, but it works roughly. Pure has a smaller step on all axes, but takes much more time. When creating a path, you need to upload a file stl, specify the thickness of the material, and also the bit for the finishing and roughing path, then in the final path, you can choose the way to create the picture in the last step: one-way, two-way, radial and ect.

Neuro-technologies

within the Technologies class we visited the amazing space opposite the LABA space, where scientists investigate the features of the human mind and consciousness by special devices, including software of mobile phones.
   
The picture demonstrates my level of mindfulness and concentration, which is evidently about 0. It’s pretty funny, because if you strain, the level grows noticeably and you can `blow up the barrel` (like in a computer game). Being a cheerful and tired nature, it was hard for me
   

Thus, wearables are being designed to improve not just physical health but mental well-being as well. Meditation apps in tandem with consumer EEGs like InteraXon’s Muse  aim to help users build concentration and self-regulation skills. Even general-purpose fitness wearables are starting to include mental health and training applications. Jawbone (through its subsidiary BodyMedia) has secured patents that consider physiological and contextual factors. These are also systems that focus on improving learning and skill acquisition across the extended workforce through online interactive platforms and cognitive simulation models. Human capital-intensive organizations such as AT&T and Accenture, and start-ups such as Applied Cognitive Engineering, are developing multiple applications in the area, and securing relevant intellectual property rights.

TOWER – GNM

Assignment Parameters:
The assignment was to construct a tower using press fit laser cut modular pieces with a dimensional 
limit of 150mm on the length. 

Materials:
Modular patterns were restricted to 3 patterns or modular units.
Laser Cut plywood

Modular Units for Tower Structure

Pre-Design - Conceptual approach:
The concept was based on attainment of the maximum height without compromising the structural 
integrity of the tower frame. with these two parameters as the basis, it was evident that 
additional stability could be attained by the use of a cross-pattern of "beam" structures. 
Horizontal elements were left out. 

Iterations and Re-Design:
In line with the initial concept of simplicity, there were few iterations between the initial 
design and the final version.

Assembly of Tower

Fully Assembled Tower

Troubleshooting:
The initial design had stability issues due to the initial proposal of framing the beams using 
continuous interlocking. This made the initial design heavy. Whereas the interlocking pattern 
was maintained for the base in order to keep the structure stable, the interlocks were discarded 
at the subsequent upper levels, making the structure lighter and allowing for attainment of 
increase height.

Cutting & Assembly:
Cutting out of the modular units was done using a laser cutting machine.
The cutting process took about 45 min.

The Team

Credits:
Whereas the final product was a product of active team work on the part of all team members, 
the cutting work was conducted under the guidance of the course supervisor Ivan Mitrofanov 
since at the time non of the team members could conduct the cutting works independently.
Class : Technology

Software : Arduino IDE

Equipment : Arduino UNO Board, HC-05 Bluetooth Module, Breadboard, Jumper Wires, Fan

Challenges :
  • Making proper connections from Arduino to the components.
  • Understanding the Rx and Tx connections from Bluetooth Module to Arduino.
  • Programming the code.


Approach:

To advance with our projects here in Shukhov Lab, it was necessary for us to learn how to operate and program the Arduino boards and perform basic activities. In this project I was trying to work with an Arduino and bluetooth module setup for controlling a DC Motor (A fan in this case) using a smartphone.

  Process: First it is required to assemble all components together and make the connections.

 

I have initially connected the bluetooth module to the breadboard and made necessary connections to the arduino board using male-male jumper cables.

 

The connection for the bluetooth module are as follows:

BLUETOOTH    –           ARDUINO

Txd  –  Rx

Rxd  –  Tx

Gnd  –  Gnd

Vcc  –  3.3V

 

Next I connected the DC powered fan to the arduino and connected it with GND for the negative terminal and PIN-8 for the positive terminal.

I chose pin 8 here because I have activated it in the code using the statement (int ledpin = 8;)

The connections to the arduino board are shown on the image below:



Finally we upload the developed code to the arduino board.

*NOTE:
  • It is very important to disconnect the Rx and Tx cables from the bluetooth module before uploading the code or it might display an error.
  • Always disconnect the arduino power source before making any wiring changes to avoid short circuit.
  The code which I used can be found below:

char val;

int ledpin = 8;

void setup() {

pinMode(ledpin, OUTPUT);

Serial.begin(9600);

}

void loop() {

if( Serial.available() )

{

val = Serial.read();

}

if( val == ‘H’ )

{

digitalWrite(ledpin, HIGH);

} else {

digitalWrite(ledpin, LOW);

}

delay(100);

}



  I have also downloaded an application on my phone, from which I can send signal to the Bluetooth module.

It is necessary to download this app or a similar app. You can download one from the link below:

https://apkpure.com/arduino-bluetooth-controller/com.giumig.apps.bluetoothserialmonitor/download?from=details  

After uploading the code, I disconnected the power from arduino board connected back the Rx and Tx cables and plugged back the power source into the arduino (it can be from your notebook’s USB or via 5V power adaptor)

Next I opened my bluetooth settings in my phone and paired the device with bluetooth module HC-05.

*NOTE: 
  •  In case of password prompt, use – 1234
  •  Typing H on the bluetooth app activates signal and typing anything else switches it off.


Then open the app (arduino bluetooth controller) and select the device (HC-05) from the list of paired devices and connect with the switch or terminal modes as shown below. In my case I have used the Switch mode and set the parameters for ON button as “H” and OFF button as “X”. Otherwise you can manually use the Terminal mode.



The fan rotates on sending the signal “H” (ON) and switches off on sending signal “X” (OFF) successfully.

It is demonstrated in the video below:
