#ADAFRUIT TRINKET SCHEMATIC DRIVER#

During output week I did get a stepper stepping using my version of Neil's bipolar stepper driver but mine was a little inconsistent and I wanted this machine to be as reliable as possible. I milled and stuffed the circuit boards at home using Clank with the exception of the stepper drivers. What parts and systems were made? What processes were used? This is not included in the BOM but you can find info about that here. Depending on access to 3D printing services, this could add considerable cost.ДЄlso, I used the clank PSU to supply 24V to power the stepper motors. Something significant that is not included are the 3D prints which were done on the ABS printer in theДЄrchitecture shop. Some of these parts I purchased, others were from the fablab What materials and components were used? Where did they come from? How much did they cost?ДЄ bill of materials for basket buddy 2.0 can be found here. I designed and programmed the interface shown in the video in OpenFrameworks. I designed the two circuit boards used in the project though the schematic for the microcontroller board is heavily based off of one from Jake found here. Modules two and three was based off of the z-axis of Clank. The design of the feed mechanism is based off of the filament feed on a 3D printer. Some of my early ideating was also inspired by the D.I.Wire in terms of the overall design and in thinking about a machine that transforms a linear material into something that can be Most notably for me is the collaboration between Aranda/Lasch and Terrol Dew I haven't seen a machine with this functionality before but there has been some previous work that applies computation and digital fabrication to basket making. Rattan is a natural material made of climbing palms. This is a machine for measuring, marking and cutting lengths of rattan, which can then used to make baskets. The basket shown in the video was programmed in OpenFrameworks based on sine and cosine functions. The Basket Buddy 2.9 interface was written in OpenFrameworks. With the AccelStepper library would be nice. I wrote this without the use of libraries, though going forward, adding acceleration and The arduino sketch is attached at the end of the page.

The stepper drivers are made by Pololu and run on the A4988 chip. In addition to the microcontroller board, I also designed and fabbed a board to house the three stepper drivers. Motors so that ended up not being an issue in this case. I broke out all of the free pins on the SAMD21E18A but ended up only needing 6 of them to drive the three stepper Is convenient but there are only pin mappings for 6 pins in the Arduino core for this board, which is not so convenient. This board is compatible with the Adafruit Trinket M0 bootloader, which The machine is controlled by a SAMD21E18A board based off of a schematic from Jake found here. All three modules are afixed to the top plate of the plywood housing. Each of these modules is driven by a single stepper motor. The machine can be understood in three modules: one for measuring, one for marking and one for cutting. To see how the project developed you can view my Final For my final project I made a machine for measuring, marking and cutting.
