This machine is built using cheap materials and doesn’t cross 7$ to build. To build this you need some patience and 2hours of time. And you must be familiar with soldering and wiring since this involves a small circuit. Once it is built just plug in this device to your computer and run the required content to be written and it will start the job in no time. This I have called writing machine since it uses a pen to write the things. So let’s build your own writing machine.”
