what is a Makerspace culture?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino senses the environment by receiving inputs from sensors and can control lights, motors and actuators.
what is the difference between arduino and Raspberry Pi?
An Arduino is a microcontroller motherboard
It is very easy to use
Raspberry Pi is a general-purpose computer, usually with a Linux operating system, and the ability to run multiple programs.
features of arduino
Operating Voltage: 5V
Input Voltage (recommended): 7-12V
Input Voltage (limits): 6-20V

what kind of plastic do you use in 3D printing
The plastic used is called PLA, it is manufactured using renewable raw materials such as cornstarch. PLA is the easiest material to print
PLA is biodegradable
In general, PLA filament settings have an optimal printing PLA temperature range from about 185C to about 205C
ABS Plastic is a copolymer of Acrylonitrile, Butadiene, and Styrene, and generally possess medium strength and performance at medium cost.
Acrylonitrile Butadiene Styrene
a petroleum-based non-biodegradable plastic
this product contains no toxic chemicals
ABS has a strong resistance to corrosive chemicals and/or physical impacts
3D printing materials and more
some materials used in 3D printing
ABS: (Home printers)
Resin: (Multiple options)
gold and sliver
even food can be printed with Foodini
retail price is $1,300
Foodini is a 3D printer for foodstuffs. Its Florida-based makers are hoping their time-saving device becomes as ubiquitous on kitchen countertops as the microwave oven has become
some interesting objects you can 3D print
An artwork, by Dutch artist Diemut Strebe, has made a replica of Vincent van Gogh’s left ear. It is not made of plastic, but living cells derived from tissue supplied by van Gogh’s great-grandson.
Robotics is an interdisciplinary branch of engineering and science that includes mechanical engineering, electronics engineering, computer science, and others.
types of robotics
Domestic or household robots
Hobby and competition robots
other types of robots by locomotion and kinematics
Articulated robots (robotic arms)
Single wheel (ball) robots
Three and more wheel robots
Bipedal robots (humanoid robots)
other number of legs
Mobile spherical robots (robotic balls)
There are six main types of industrial robots: cartesian, SCARA, cylindrical, delta, polar and vertically articulated. However, there are several additional types of robot configurations. Each of these types offers a different joint configuration. The joints in the arm are referred to as axes.
what is the difference between a machine and a robot?
Originally Answered: What is the difference between the robot and the machine? Machines can precisely repeat predetermined motions. Robots can do that too, but they can do even more. Robots can be programmed (given instructions) to perform many tasks.
to make the exact size for your project
set up the lazer cutter
design simple shapes
or more complex designs like Silhouettes and scans
beginners start cutting on cardboard
later cut on wood and other materials
how accurate are lazer cutters?
New laser cutters have positioning accuracy of 10 micrometers and repeatability of 5 micrometers
This process is capable of holding quite close tolerances
what cant be lazer cut?
Emits chlorine gas when cut
Emits chlorine gas when cut
Melts / Cyanide
burn / smoke
Coated Carbon Fiber
Emits noxious fumes
The laser is not designed to cut food
HDPE/milk bottle plastic
Catches fire and melts
what is makerspace
a place in which people with shared interests, especially in computing or technology, can gather to work on projects while sharing ideas, equipment, and knowledge.
