Full on picture of a canvas, that a robot spraypainted some abstract art and a cat on

A close up picture of some automated spraypaint art

After a request from the artist Jascha Müller, I got to work on building a spraycan gondola for my wall painting robot.

Read more about the build and the very first test run in my latest blogpost olivier.berlin/dot-bot-spra...

Electronic Kalimba – olivier.berlin

I wrote a blogpost about my Electronic Kalimba project. It is a 15 minute read but filled with lots of pictures 😄

A short video about my #opensource Electronic Kalimba project. With each iteration, the instrument gets more refined and I love the way it plays.

I got offered a location for some #robotic spray painting #experiments, and I am currently building a new painting gondola for my existing (custom) #drawing robot that can then also carry a #spraycan. The first pieces are coming together nicely and I am stoked to see if this works #arduino #maker

Here is a short timelapse of my cleaning robot Benjamin showing him randomly bumping around and cleaning my floor in the process. Just for fun, I let ChatGPT write all the code 😁

Picture of a seagull looking straight into the camera. Super symetrical face, beak just an oval shape. Standing in sand. Sea in the background.

Just a silly picture of a seagull I took last week #photo #photography #animals #beach #seagull #ostsee

I designed and built a simple cleaning robot, that can push a dust cloth (Swiffer) autonomusly through my appartment. It is powered by an #ESP8266 and only used components I had laying around. olivier.berlin/the-cleaning...

@bahn.de Danke, dass ihr den Halt der RE3 (3308) am Gesundbrunnen mal wieder habt spontan ausfallen lassen, und alle Menschen habt stehen lassen. Danke auch, dass euch diese Idee eine Minute vor dem Halt eingefallen ist damit niemand mehr umplanen kann. Zeit, sich ein Auto zu kaufen 😒

A crow holding a nut in her beak, sitting on a balkony railing, with the Berlin TV tower in the background.

Today, I played a bit around with a motion detection software on my iPhone, and I managed to capture some really cool pictures of crows. Here is one of my favorite, of a crow holding a nut in its beak. #Berlin #TvTower #Crow #Nut #Nature #Photography

An alternative key layout for the Electronic Kalimba Project, with the layout of a keyboard on top and a flipped layout of a keyboard on the bottom

I just designed an optional and alternative layout for my #opensource #esp32 Electronic Kalimba project. Since the lower PCB contains all of the electronics, the upper PCB can be replaced in seconds to a different layout. A keyboard arrangement was the most requested layout so far 🎹🎹 😁 #maker #kicad

A foto showing a finished plotted picture of animals that are artistically combined with food items. The image was plotted with the new gondola I designed for my Dot Bot project

I wrote a blogpost about my latest drawing robot upgrade. If you need something to procrastinate for about 3 minutes, feel free to check out this link olivier.berlin/dot-bot-gond...

Ich nehme mein Fahrrad tatsächlich oft nicht, da ich es extrem ungern draußen stehen lasse. Heute ging es nicht anders, dann müssen halt 2 dicke Schlösser mit und den Akku lass ich auch nicht am Rad... Mir wurde in Berlin schon ein mittelgutes Fahrrad im Innenhof geklaut, es hatte auch 2 Schlösser:(

A silver ring with a 3D feather, made in a lost wax casting.

A silver ring with a 3D feather, made in a lost wax casting. In the palm of my hand

The Blender view of a ring I got casted in stirling silver

I recently designed rings, and had some of them casted in stirling silver in a lost wax process casting by sculpteo.com. It is crazy that we live in a world where you design something in Blender, pay a few bucks and then get it delivered in the mail.

Today I worked on the nodejs websocket server that the Electronic Kalimba can connect to, to send its keystrokes as Midi over WiFi. I must say the delay is pretty usable!

Here is a WIP of my latest project, my E. Kalimba V3.0. It is a sandwich of two custom (hand solderable) PCBs, with 80 tactile buttons and lots of other stuff going on. Powered by an ESP32 controller, dual analog wave generators, battery powered, programmed with Arduino and everything open source.

Thank you for taking a stance. We live in strange times. I myself lost interest in everything spacex related, and even stopped clicking on most of your space news videos because I find Elon as a person completely insufferable. And I used to watch spacex launches together with friends on livestreams
