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
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 …

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
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)
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
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.
