Tri State Area

To make the coasters, I first design something on the computer that is related to the set I am making. For example, when I was making the New Zealand coasters, I did some research on their national icons. When I found something, I would search for a picture of it that I could use. I would then reformat it so it would look good on wood. Once I had 6 coasters, I would laser cut them. After they were done, I sanded the burned parts and sprayed it with a sealer that would make it waterproof.

Copying one code from a Raspberry Pi to another. Trying to set up a second hydroponics system.

#!/usr/bin/env python

import RPi.GPIO
import time
import sys

# The Raspberry Pi pins used to control the power strips
setPin = 3

RPi.GPIO.setmode(RPi.GPIO.BCM)


runTime = int(sys.argv[1])

timeUnit = 'sec'

try:
    timeUnit = sys.argv[2]
    if timeUnit == 'min':
        runTime *= 60
except:
    print("")
    print('Defaulting time units to "sec" (other option: "min")')
    print('> ' + sys.argv[0] + ' sec')
    print("")

    
#Set up the pin as an output    
RPi.GPIO.setup(setPin, RPi.GPIO.OUT)


print('')
startTime = time.strftime('%a, %d %b %y: %H:%M:%S', time.localtime())
print("Start pump at:", startTime)

#Turn pin on
RPi.GPIO.output(setPin, True)
print('on')

for i in range(runTime):
    time.sleep(1)
    if i%10 == 0:
        print( '{t}/{n} sec. ({p:.1f}%)'.format(t=i, n=runTime, p=100.0*i/runTime) )

#Turn pin off
RPi.GPIO.output(setPin, False)
print('off')
endTime = time.strftime('%a, %d %b %y: %H:%M:%S', time.localtime())
print("End pumping at:", endTime)

This is Blas’s icosahedra and tetrahedra set that was made as a math project. Then he made it for a present. Later on the Makerspace Business Club started selling them. A tetrahedron has four sides each side has a triangle face. With that in mind Blas decided to add puzzle edges to the sides of the triangles. Inside the big tetrahedra there are a bunch of triangle sides that are used for having fun and creating cool things. It is possible to make an icosahedra with the little triangles. Each edge of the small triangles have either one or two tabs for attaching one to another. Which means there are four different types of puzzle piece. They are fun to play with.
