Build a Drawbot from Two CD Drives and a Raspberry Pi #piday #raspberrypi @Raspberry_Pi
Donald Bell over at Make posted about this great tutorial for a drawbot!
You may not know it, but your old computer CD ROM drive is a treasure chest of useful components. Inside you’ll find stepper motors, rare earth magnets, bearings, and coils. It’s enough futuristic-looking greeblies to construct your own Star Wars prop, or maybe even your own portable CNC drawbot.
To prove the point of what can be done with a few repurposed CD ROM drives, Norbert Heinz popped open a pair, stacked them perpendicularly, wired up their stepper motors to a pair of H-bridge driver boards, and controlled his new creation with a Raspberry Pi.
The result is a CNC Pen Plotter that can move on an X/Y axis. To take it further and add the ability to have the pen automatically lifted from the surface (on the Z axis), Norbert added a simple servo to lift or drop the lightweight metal arm that attaches the pen to the unit.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE.
