Making Art using 220V

I have a rol of printer paper that was used by an old 8bit computer. I forgot which one, one out of my collection.

Fractal-like ‘art’

I dont think it is thermal paper, maybe the printer uses electricity just like the movie clip you see below. (Well .. not using 220V directly on the paper maybe) 🙂

Having fun at our old place during moving to Hilversum.

3D Printing

In 2012 I started with 3D printing, I didn’t have my own yet. So it was done using shapeways.
April 2019 I ordered my own, a Creality CR-10S.

Specs

  • Build Volume: 300 x 300 x 400mm
  • Layer Thickness: 0.1-0.4mm
  • Positioning Precision: Z-axis – 0.0025mm, X & Y-axis – 0.015mm
  • Nozzle Temperature: 250°C
  • Printing Speed: 200mm/s
  • Filament Diameter: 1.75mm
  • Printer Weight: 9kg
  • Printing Filament: PLA, ABS, TPU, Wood, Carbon fiber, etc.
  • Input Support: SD card/USB
  • File Types: STL/OBJ/G-Code/JPG
  • Supports(OS): Windows/Linux/Mac/XP
  • Printing Software: Cura/Repetier-Host
  • Frame & Body: Imported V-Slot Aluminum Bearings
  • Power Requirement Input: AC110V~220V, Output: 12V, Power 270W
  • Output: DC12V, 10A 100~120W (Support storage battery)
  • Working Condition Temp:10-30°C, Humidity: 20-50%

Problem with this 3D Printer is the lack of a thermal runaway detection. My solution is a MQTT/Nodered warning system which plays an alarm and uses a shelly to disconnect the power.

Software I Use – see other posts

  • Openscad
  • Cura
  • Meshroom
  • Blender
  • Sketchup

Hardware

  • Octoprint on a raspberry pi – (with Octoscreen)
Octoscreen (image from internet) I’m using a faytec touchscreen monitor
  • Octoprint monitor
Little display on my desk which monitors the progress

I’m using a filament sensor like the one in below picture

It used to be a DIY thingy using an arduino. (below)

Hints and tips

  • Use painters tape against bending of the glass, it will warp because of the heat.
  • Use 3D spray to fix model to base-plate.
    (I used a gluestick before)
  • Always think of model placement, less support the better.
  • Try to remember which fill-in is the best for your purpose.
  • Calibrate distance print tool and glass using printing paper.
  • Know your printer, make a lot of test prints when starting.
  • Learn / read about 3D printing finishing. Sanding/smoothing/melting.
    I’ve got some smoothing liquid (print coating) , a dremel and below tool
  • Use a print model to test your leveling

  • Learn how gcode’s work!

3D printed a stone

Why? Because i can

While on holiday in New Zealand i made photos of a rock i found on the campsite we where. Nothing special about the rock, but it was a nice subject to try to replicate.

So i took many many pictures of the stone from all sides.

Imported those images in meshroom and convered it to a 3D stl object.

Welding course

Over a period of a few weeks i did a welding course, where i learned to weld with : Mig, Tig, Stick and Gas

I only did point welding, way back in school.

After the course i decided to buy a stick welder.

Password fun and tips

See my other bofh page

Never ask me to reset your password, i you are to stupid to remember or not using a passwordsafe … I WILL give you a new password, and you WILL remember not having to ask me again. 🙂
On this day i drew some example pictures for colleages.

Okay .. now some tips to create uniq passwords for every site in you head.

NOTES! .. CNN example uses google as secret key ..

Own made clock

We made our own nerdy clock.

We took a big clock and covered the backplane with modeling grass.

It took about 5 containers to fill the backplane enough to get it nicely filled.

The lettering near the pictures are the RGB representation of the color used in our office.

Lets see if you can decode them all. (use password clock to view solutions!)
