Tri State Area

I recently added everything I make to the Makerspace Business website. That includes coasters and ornaments. The link is below:

For Makerspace, I needle pointed (which takes a lot of precision) and I made signs with the laser cutter for the place where my uncle and I hike.

I tried making a sticker for my camera flash. I was going to put a smile face on it; however the face was too small and weeding ruined it.

For the past couple of weeks I have been choosing a different part of a 1984 Vespa engine to work on every day. After I choose a part I take it off to learn about it. After fiddling with it enough, I can usually figure out what it does based off of my basic knowledge of engines and how they work. Once I have figured out the function, I inspect it to see if there is anything that might be impeding its ability to do its job. I clean whatever might be in the way and put the part back on to the engine. So far I have finished the carburetor, the combustion chamber and the muffler. It doesn’t appear to have any major issues, just a whole lot of grease that needs to be cleaned.

I have been working on two websites: the first one being the website for the Makerspace Business Club, and the second one being the macro-invertebrate log for the ITEF grant. Neither of them are done yet, but the both of the websites are up and (more or less) functional.

Too set up your stepper motor you first need to make the circuit. You can connect the motor straight to the raspberry pi if you would like. I used this link. Make sure you know what GPIO you use for the four inputs.

Next, you need to set up the code. I used the link below for the initial code and then modified it to specific uses I wanted the motor to do. You will need to put parentheses around all the print statements.

I wanted to control two motors, direction and how many rotations the motor spins for. For that use the code below.

from time import sleep
import RPi.GPIO as GPIO
import os
import random

        self.time = 0.001

        GPIO.setup(IN1,GPIO.OUT)

During the interim last week, I made snowman ornaments in Makerspace Business. I made a basic design of three overlapping circles, and then designed a hat. I then had to figure out how to make an outline that cut out, and if I did it the way I am used to, I would end up cutting out three circular shapes with an oblong piece missing. So I had to make arcs on the outside, about 1/8 of an inch away from the snowman, that would cut out. I then added the words and finally printed it out on clear acrylic and on wood.
