I just wrote a blogpost about a project I did a while back when I developed an autoclicker, to solve some crosswords https://olivier.berlin/crossword-auto-solver/

My last creation is online. I got carried away while designing a weight. Here is the blog entry https://olivier.berlin/3d-printable-grandfather-clock-weight/ and here you can get the model for yourself 😀 https://cults3d.com/de/modell-3d/gadget/pine-cone-hollow-screwed-together-fillable-grandfather-clock-weight

@darekpages I plan to refill Edding permanent markers with their refilling ink. The ink however is quite sticky and dries fast which prevents me from using motorized syringes. What I learned from my previous plots is that my pens use ~1 g of ink per hour of plotting. And when I refill them after one hour, I get a noticeable color change which I don't like. And refilling more often is tedious. So this is my overengineered solution 🙃

To refill my pens during large plotting projects, I designed and built a tiny peristaltic pump. It only moves ~1 ml of liquid per minute, but even that is way too much. I only need 1ml per hour. But a good thing is that pumped liquid remains in the tube which means I can power on the pump for a few seconds every few minutes. The pump runs on 4V DC and consumes ~30 mAh.

This weekend, I added the ability to my drawing robot to understand gcode, the file format that is most commonly used for #CNC machines, #lasercutter and #3dprinting. Here is an image that was prepared for a laser cutter. Also it is the first #plot that did not use a thick Edding marker but a fineliner, and I must say I am impressed by the precision of my bot that currently has a drawing surface of 3.5m by 2m (and a max surface of 7m x 7m).

Another wall plot by the dot-bot. #plotter #maker #art

@falko and I designed, 3D printed, build and programmed a wall plotter from scratch which can now plot things as big as an entire wall. Here is the latest test picture.

Ok, next try. @falko told me that I need to provide more information. I designed and built a 3D printable, working replica of the Titanic's engine from old blueprints that I found in books and on the internet. She was meant to be printed at an scale of 1:75 and run on a small compressor but I couldn't get her to run due to friction issues so I reprinted everything at a scale of 1:37 and now I can hook up my vacuum cleaner to the exhaust and she just flies.
