About

This site is where I post all kinds of random projects. Photos of small projects can be found on my Instagram.

I have a very theoretical job during the week, which I like to complement that more applied and simpler projects that take days instead of months/years. That’s why I build a CNC router during my master’s thesis, build a laser engraver recently, and also have a small metal lathe, a 3d printer, some welders, drill press etc. etc. with which I can very quickly turn an idea into a cool weekend project.

  • PCB business card goes global

    PCB business card goes global

    After my PCB business card was featured on hackaday.com, on Instagram, and even on twitter on a thread with Dave Jones from the EEVBLOG. (And I’m pretty sure they even mentioned the battery holder on their podcast The Amp Hour.) I was contacted by Antriksh from Payuta that organizes hardware security conferences such as Nullcon …

  • PCB business card

    PCB business card

    Motivation The main reason for designing this was that I came across another PCB business card that was poorly executed and very expensive to make, so I decided to make a better one. I wanted one that had Snake because Snake is awesome, and a two-player game that you can play with perhaps a potential …

  • A4988 stepper driver repair

    A4988 stepper driver repair

    2 out of the 4 stepper drivers I recently received arrived broken. A quick check with a multimeter showed that the potentiometers used to set the maximum current were defective. Without time to wait for replacements, and without this package of smd potentiometer on hand, I decided to just solder two 0805 resistors in place. …

  • TL smoother on Creality Ender 3 pro

    The effect of TL smoothers is very dependent on the type of 3D printer, in the case of the Creality Ender 3 pro there is a noticeable difference when adding TL smoothers on the X and Y axis, adding additional smoothers on E and Z had no noticeable difference and doesn’t really fit inside the …

  • Wood fineer clock

    Wood fineer clock

    I had some food fineer from another project, and wanted a clock for in my bedroom that automatically adjusts the intensity based on the ambient light intensity. I’ve designed the PCB so that 4 of them interlock, with 3d printed 7 segment dividers and wood fineer glued to that. The entire thing is driven from …

  • Electronic current sink (0-30A 0.11°C/W)

    Electronic current sink (0-30A 0.11°C/W)

    I needed a way to test a power supply I got from eBay, the issue I was facing was that it was a 48V7.5A power supply, so just hooking up a couple of resistors or bulbs wasn’t going to work. I figured this was a good excuse to finally make myself an electronic load out …

  • Decade resistor box

    Decade resistor box

    Inspired by an EEVBLOG post, I made a variable / decade resistor box. It consists out of 7 thumbwheel switches with resistors soldered across every position.

  • Dial indicator box

    Dial indicator box

    I found a beautiful Mitutoyo dial indicator on an auction site, however it came without a box so I made one. Machined from a sandwich of hardwood and beech, with soft foam to hold the indicator and magnets to hold it shut.

  • Wooden pen

    Wooden pen

    Some projects just present themselves. I saw a picture of a shopmade pen online, figured I could make a nicer one. Was looking for a project to do during the holiday and had a nice piece of walnut that I sealed in wax years ago. Couple of hours later I had the design ready. Not …

  • Pizza cutting board

    Pizza cutting board

    The idea for this cutting board came during one of numerous pizza dinners, where it’s quite difficult to divide a pizza into for example 7 pieces. The original cutting board was machined and filled with hardwood inlay. A few years later when I finally had my laser engraver working, I gave a laser engraved version …
