BrachioGraph

The world's cheapest, simplest pen-plotter. Python-powered.

Parts: ~€14. Build-time: ~1 hour.

I made a web site that prepares images for @evildmp's @BrachioGraph pen plotter for #raspberrypi: https://t.co/902TyH2vN9

Now it's easier than ever to get started with the BrachioGraph and create some funky robot art! 🤖♥️✏️

Coming soon to BrachioGraph: software correction for servo-motor hysteresis and mechanical free-play/lack of rigidity in the hardware.

In the second image, grid lines drawn forwards and backwards exhibit much less misalignment than those in the first, thanks to error-correction.

Understanding how the plotter's geometry affects its drawing area: https://t.co/pX5SbLsHOi.

Some interesting forms can be discovered, including a representation of Donald Trump's hair.

@christiank79 @christiank79 BrachioGraph will be attending PyCon Namibia https://t.co/mUR4KzJFaa, where its ancestor the PantoGraph made its first appearance.

I would say it’s the highlight of day 2 of @PyConNA: a cheap pen plotter by @evildmp

@CiccioSPICE Potresti aprire un issue a https://t.co/dUG030ZuMc; qualcuno forse avrà un'idea.

BrachioGraph worked very hard at PyCon Sweden, especially drawing beards.
