I like the way it hiccups when it lifts the pen 
this is just what we want for our paper calendar with the webcam in the space

That’s a very cunning arrangement of servos to do the drawing. Love it.

It’s a posh version of the one we 3D printed in November 15 !
Very cool

! That is AWESOME. Want.
i’ll dig out the files - its 7 pieces on the 3D printer, 3 x £3.00 small servos and an Arduino Nano - £5.00
The pen is a standard 50p white board marker
I can put the code on GIthub if you want to make one

Yes please!
OK, will dig out the 3D and Arduino files
The original idea was to hang it over the top of a white board I have in my office and let it draw in the corner but the little bugger kept dropping the pen on my head…

Hi All
Anybody else seen the Penman, a turtle drawing robot for BBC Micro in 1985.
Video https://www.youtube.com/watch?v=mR8enP09RPI
Review http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=5345111
Controlled by a 6803 (a 6800 CPU with 2 Kbyte RAM), apparently 50 mm/sec with 0.07 mm accuracy, with commands akin to HPGL or G-code over RS-232.
The three-point-turn method of drawing straight lines is astonishing: just visualise the trigonometry involved!
Kind regards,
Jonathan.

Through the haze of my memory, there was definitely some logo, driving a turtle, at school when a kid. One thing I’m clear on: no it didn’t involve that kind of trigonometry =]
Only slightly more on topic, the Jack in that video is a legend in my world, part of the now (twice) defunct BERG.
Totally - and I instantly saw the design DNA from Berg’s little printer when I saw this…
