Weather plotter

thingiverse

Here's our take on the plot clock, plotting the weather or anything else you like using API addresses. Our lightweight design is modern and sleek, allowing you to see the action inside the plotter through its rounded surface. The paper wrapped around the construction will slide across the front showing the things written on it by the plotter. For instructions in how to assemble and calibrate the plot clock Follow the link http://www.thingiverse.com/thing:248009. We've made some small modifications on the height of the construction and adjusted the size of the pen holder (arm) so that it fits the pen we've used for our version. We recommend that you adjust the size in a manner that fits your own pen. Instead of using a pen and an eraser, we have used a stepper motor and a paper roll. The stepper motor is calibrated to move every time a symbol is written and every time a message is done. We've made some additional clips, so that the paper will be tightly held down to the surface of the writing station. We've used and modified the arduino-sketch code from the plot clock so that it will not only write the time, but as well plot the weather using an api address and write whatever tweet you send to #machatronics. In addition to the basic code we've made a library with letters that the servo motors can interpret as movements. We developed this system in collaboration with IBM in the DTU course Design of mechatronics to get an introduction to cnc based technologies. We've used their IBM software from http://nodered.org to communicate with a NodeMCU(esp8266) which allows us to basically write whatever we want from an api address and onto paper with the plot robot. All electrical wiring is led through holes in the back into a box on the back, where the nodeMCU is placed. Our design is based on a simple system where everything is mounted to the back of the construction. To minimize the use of bolts we've developed small "T" shaped pieces to mount the pieces to the back part.
