Pi Wars 2024 - Dynamometer
For Pi Wars 2024 we are using RTClib-lite board. (team blog) This is semi-open hardware/software solution for controlling differential drive robots. It's having ao. good working odometry on board, enabling deadreckoning. This configuration has proven itselfs already multiple times (like many RoboRama tournements) as a high quality robust drive platform. But driving a robot precisly […]
Pi Wars 2024 - Distaster zone
Ever heard about Pi Wars? Pi Wars is a non-destructive, Raspberry Pi-based robotics competition with both autonomous and remote-controlled challenges. It takes place in-person over a single weekend and features teams of school students, families and hobbyists as well as solo roboteers. The event open to anyone on planet Earth! I joint a small group in The […]
Core XY printer
Currently there is a hype in changing a FDM printers into a multi print head system, like ZGE Mark2. With my Ultimaker 2+ this is quite challenging: A core XY setup could be organized different, so one side of the printer is completely open. The next challenge: After many design iterations, it was time to […]
Dual material/color printer
Ultimaker 2+ printer is a great tool to own. The printer still always works. But it lacks a second color (/material) option. The 1st generation UM2+ printers were already prepared, supporting a second extrusion train: heater & feeder. Also the Marlin code is prepared for this. So adding steppers & heaters is quite straight forwards. […]
DLP printing
August 2013: A while ago, I was inspirited by a nice movie from Oliveira Jose about a DIY SLA 3D printing device, working with a (modified) DLP beamer. I had still a lot of questions, on how this process was working. Finally after reading a building blog on instructables by Tristram Budel, I decided to […]
CNC milling
For a while ago, I wanted to create a big cnc router. So I needed some tools to build this. Therefore I bought the HBM250, which is a mill-turntable combination. Because that combination is not very handy, I bought an additional XY cross table, for mounting the BF16 mill. Later I also bought some stepper […]
Lasers & Galvo's
Laser shows are cool, so why not build my own? There are a lot possibilities for building a laser scanners. It's all about speed and accuracy. Some people use galvo meters, some others use speakers. My first attempt was to use the computer speakers and control this with my soundcard & a text-to-wave-file-converter. But unfortunately […]
