Charcoal is made by burning (cooking?) wood in an oxygen-starved environment.
I took a tea-leaf tin (bought in Tokyo many years ago, sad to see it go), and punched a small hole in the lid. For my first test I used cuttings from a blackcurrant bush that has been left to dry outside for a few seasons. I looked for fairly straight pieces, cut them with garden shears to fit in the thin, and put the lid on. In the evening, I made a fire in the wood stove, and placed the tin in the flames. I just left it there until the next morning.
The result turned out really great, and I especially liked that all the fine delicate details of the twigs stayed intact, even most of the bark stayed in place. I was also surprised that none of the twigs snapped. Even the thinnest came out perfect!
What’s next? You can see my first test drawing towards the bottom of this page, and I’ll update this page with other drawings later. I’m especially looking forward to testing charcoal made from different trees and shrubs, to see if there are differences.
Update: If you are an artist and want to test my charcoals I’d be happy to send you some. Send an email to email@example.com. I’d love to get your feedback on how they work compared to commercial drawing charcoals.
Now, I don’t want a car that only looks dangerous.
I want the car to be fricking dangerous!
So no rubber spikes or decals with nuclear waste symbols. Just real, nasty, rusty nails and junk, placed to cause maximum damage if it crashes into you (or explodes). And perhaps a tiny coil gun cannon, or a grinder of some kind, or a flame thrower?
This is going to be awesome!
Autonomy with arduino. If you move, it will hunt you :)
Long range fpv. 4 km?
Run the engine on methane.

This has been on the todolist for a few years, but today I finally got around to building my first drawbot using Arduino. I wanted to make something that was light, minimal and portable, that can be added to any flat surface with a gluegun. I use small steppermotors with bobbins (from eBay) and thread from a sewing machine to lift a coin with a sharpened charcoal-stick though the center, and a solid metal picture frame as a base.
Version 1.0: Running Polargraph Controller software
The machine is now running the Polargraph firmware, controlled via serial from a Processing app on my laptop. It took a bit of tinkering to get the firmware to run with my steppers and drivers, but once it was up and running it worked pretty well.
Run the machine on grbl firmware and test other controllers.
Testing a variations of pens and paper.
Build more machines! Some of the motives I’m working on takes up to 12 hours to draw, so to increase the learning curve I would love to have at least a few more up and running.
Vi ble invitert til barnefestivalen Juba Juba for å holde vårt Postapokalyptiske figurverksted av gjenbruksmaterialer. Festivalen ble en stor suksess, med publikumsrekord for figurverkstedet, nydelig vær, og masse unger (og voksne) som lagde tusen morsomme figurer, mutanter, økokriger, romskip og rare greier i to hele dager. Tusen takk til arrangørerene for invitasjonen, vi kommer gjerne tilbake neste år!

Ye. Det er ikke så ofte jeg brygger, og en av grunnene er at det blir litt mye mikkmakk med å lage oppskriften. Lat skal man være. Så jeg har brygget et par øl der jeg har tatt ting litt mer på sparket når det gjelder spesialmalten og humla. I stedet for å finmåle, så brukte jeg måleenhetene “en neve” og “en hånd” på dette ølet. Og godt ble det, spesielt flaskene som fikk stå lenge, med fine florale toner og flott balanse.
