final proyect

vectorial mesh to print

Due to these problems I have been forced to reduce the scale of the prototype almost in half, and delimit a bed at the base to prevent it from getting up.

This is the configuration

and the print process

to the final result

in this prototype, and with a certain scale, I have tried to simulate the cords of pouring of concrete. the company collaborating in the project (bemore3d) will use a 600 mm or 900 mm extruder depending on the type of concrete used. this depends to a great extent, in turn, on the setting time, the ambient temperature and the type of arid that is used in the mixture (a patent that I m afraid I can not detail because I do not have access to that information)

the pantheon in its real construction will have a wifi server. in its location there is no wifi signal, so the idea is to generate it within the pantheon itself with short range.The objective is for all visitors to have access to the web on their mobile phones, which is the real reason for the pantheon: the burial of "dada" digital poetry.

router example
ACTIVEPOEM. kinetic poetry from dada inspiration

given the rules of fab academy I try to simulate this wifi configuration with two tests with different components

esp2866 feather HUZZAH

first reading about : " you can program it like any normal Arduino or other microcontroller. And on top of that, you get Wi-Fi communication, so you can use it to connect to your Wi-Fi network, connect to the Internet, host a web server with real web pages, let your smartphone connect" so it seems to fit what I need

programming : semms to be programed in c, using LUA interpreter, using microPyton firmware and arduino IDE

there is different versions so I decide the adafruit feather HUZZAH because there is several components added: 3.3v voltage regulator the usb to serial connection and 4mb flash memory

cautions: runs in 3.3v !!!, so do not use 5V USB-to-Serial converter, or 5V sensors
The ESP8266 has one analog to digital converter, but it has a strange voltage range: 0 - 1V, voltages above 1V might damage the board
6 pins (GPIO 6 - 11) are used to connect the flash memory chip
The ESP8266 has a single analog input, with an input range of 0 - 1.0V. If you supply 3.3V, for example, you will damage the chip


then we need to download the usb drivers

silicon labs website.

however I read :"Boards with an FTDI chip should work right out of the box, without the need of installing any drivers." wich make me some confusing because Adafruit Feather HUZZAH board has it.

and here is the pin table

I connect the esp8266 and get a response

but in new connections I had again similar errors

// link to digistump // link to github 1 // link to github 2

so after trying to change the version I follow the instructions to delete and re install the package as possible solution

link to esp arduionocore forum

... but I delete all files of the esp2866 and re install with the same results



justification for use understanding that the policy of use of commercial boards of fab academy is directed to regulate its use only if necessary and occasional and as long as it appears in the work as a complement to the electronics designed and manufactured by the student, and contains a functionality difficult to grasp for this. So, and after having visited other colleagues' websites in this case, and following the instructions of my instructor regarding which boards are admissible and which are not, I refer to this model for my purpose of generating a reduced local Wi-Fi point.
