Took forever to make (next to a dayjob and various kids birthdays), but it feels most “complete”: Split Flap Electronics Beyond Prototypes (WiFi, OTA Updates, Web UI)

Not everything in a split flap display should move. Made a video about how to remove a very specific kind of visual artefact:

One of the parts I’m rather proud of: back panel cabeling. Video on the topic:
Are PCBs the better Cables - or how to wire (or not) a Split Flap display.

Figured I might also ship some code: play.flipforward.de
Probably the best „digital“ split flap display out there. With sound.

There’s a lot of „imposter syndrome“ in all of this, a lot of being clearly outside of my comfort zone, outside of my normal domain. Makes me even prouder to have my first “talk over” video done:

Came up with this idea of writing more blog posts and being a little less self critical in the process. That also means "going out there" more, but since I average around 5 reader per week, that's still a very safe thing to do. Proud of this one:

Hey, if you’re looking for someone with experience in meticulously designing a PCB to notice after everything is done that it won’t fit with the hardware constraints? Happy to chat 😀

Every once in a while I take the train to “the office” in Düsseldorf.
Not a single time has this thing been on time, and while the delays are not something that impact me, it’s mind blowing how casual a whole organisation can be in regards to quality.
It just doesn’t matter.

So I got myself a new garmin, went for a run and fucking broke my foot.
This has got to be the least lucky purchase I’ve ever made.

I built a ridiculous 1000 pixel display that takes an hour to draw an image and I'm now asking the internet to draw on it (what could go wrong?)
Please submit some 40×25 pixel art at kilopx.com!
