Every new spray test results in more stunning results. The #DOT-BOT is slowly getting really usefull as a tool. #Maker #3dprinting #maker #arduino #esp32 #KiCad #Fusion360 #art #spraypaint #graffiti #mural #plotter #electronics

www.youtube.com/watch?v=K-Vm... Here is a short video of the sprayday nr 2. It shows the #DOT-BOT, my 100% custom large scale wall plotter project, when it sprayed a huge mural in a basement in Berlin. #Arduino #ESP32 #Microcontroller #Plotter #spray #pain #art #maker #3dprinting #diy #software

In only 3 days, the next painting session is planned. Not only did the motors change, but also the gondola got a huge upgrade. Now the gondola rotates around the spray cap to eliminate a source of distortion. Also stencils and a waste tank have been added for finer lines. #dot-bot #robot #art #maker

The enclosures for my new motor controllers for my 100% custom large scale spray painting wall plotter are ready. Everything looks super clean and neat. Really proud here 😊 #maker #3dprinting #plotter #kicad #arduino #robot #hardware #art #motor #stepper

I designed new motor controller boards in #KiCad for my #drawing #robot called #Dot-Bot to add support for closed loop stepper motors. For large murals, it will be critical that lost steps are caught and no errors can accumulate. #maker #esp32 #arduino #art #painting #soldering #stepper #motors #diy

I spent the last couple of weeks working on the new software of the #Dot-Bot, and it is becomming really good. Here is my latest test, a 3D torus I rendered out in #Blender, converted in #Inkscape and plotted on my 100% self designed wallplotter. #arduino #maker #esp32 #art #robotics #plotter #code

The next big step in the #DOT-BOT journey are improved stepper controller PCBs. The new optional support for closed loop stepper motors will allow us to move the #spraycan much more agressively, without ever loosing steps!

Approximately 20k lines of code later and now my 100% custom wallplotter can draw any complex shape in a continous motion. The optimisation was nessesary to have a constant color application when using csns with spray paint. #arduino #esp32 #maker #3dprinting #esp32 #art #diy #kicad #tech

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... #3Dprinting #microcontroller #arduino #esp32 #esp8266 #CAD #KiCad #art

I wrote a blogpost about my Electronic Kalimba project. It is a 15 minute read but filled with lots of pictures 😄 olivier.berlin/electronic-k...

www.youtube.com/shorts/GuW2J... A short video about my #opensource Electronic Kalimba project. With each iteration, the instrument gets more refined and I love the way it plays. #software #KiCad #3Dprinting #soldering #maker #music #Kalimba #electronics #diy #esp32 #arduino #homemade #synth #midi

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

youtu.be/P5jRbbhXeXA 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 😁 #maker #3Dprinting #arduino #esp8266 #programming #creating #cleaning #robot #robots #ai #chatgpt

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... #maker #3Dprinting #robots #Arduino

@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 😒

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

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

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... #cad #3dprinting #3d #maker #plotter #art #creativity

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. #3dprint #3dprinting #blender #maker #3d #design

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! #Synth #Arduino #ESP32 #coding #maker #pcbdesign #KiCad #3dprinting #music #prototype www.youtube.com/shorts/hanz_...

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.
