A MEMS microphone exploded on me earlier, oh well, at least I got to take macro-shot now :3

(pardon all the dust on there 🙈)

I think I have teased this already, so here it is:
Proudly presenting “ligra”, an open source projector/projection (LiGra – Light Graffiti) platform, allowing you to broadcast your messages, your logos, your artwork, whatever you need others to hear, to whoever sees it! :3

With ligra I wanted to explore image-projection and especially projections on the cheap, so I went to my local flea market and built a platform around old camera lenses. You can find two of them in the wild at #GPN22

Almost exactly the same picture except the foreground, ligra is now heavily out of focus and the background is in focus. It is set behind an out of focus railing. The main subject is a white wall, framed in its enormous hall and pillars. It is glanced in purple red light, red light is coming from various sources in the image. There is a large white projection on the wall, it says “kein mensch ist illegal”. The projection is textured and has print marks, but no distinguishable pixels

Newly assembled boards,, 🥺

Backside of the same PCB in the same location. It shows the fog-artwork on the back as well as various labels, solder joints and connectors. The title of the board says “foxtruder [working title]”
Scenic closeup of a row of leds, two buttons and the front edge of the esp-32. Two big red capacitors are visible, blurring into the soft bokeh. Three green terminal connectors are also blurred, but visible

omg, I love when an idea turns out just as expected. Say hi to my new audio-monitor stands :3

Photo of the monitor with 3D printed legs and a wooden sheet on top. An oscilloscope rests on the board. A pink flag enters the frame from above, everything sits on a white table
Profile view of the earlier assembly. One can clearly make out the symmetrical legs and the wooden board being in parallel with the table. Inbetween the slanted monitor rests
Wide angle view of my desk with two monitors, the left one hosts the oscilloscope, while the right one hosts a computer monitor. Inbetween a laptop and a keyboard are visible

Mein schöner Lemon Lime Drachenbaum bekommt seit einiger Zeit regelmäßig braune Flecken. Ich hab die ersten Blätter eng am Stamm weggeschniten, aber nun geht es weiter. Der Baum hat sechs kleine Stämme und mindestens zwei sind betroffen. Gegossen wird das Bäumchen so, dass es eher trocken steht. Die Flecken sind durchgehend verteilt und nicht an den Spitzen konzentriert.

I never really published this, so here it is. Whenever I need a vertical USB-C power receptacle that is flush with the PCB, I use this tiny 90° adapter that I designed. It hosts a power-only type-C connector, 2 5.1k resistors and a 4.7uF MLCC, if needed.

It’s super easy to assemble and adds almost no cost. The matching footprint is in my KiCAD library allows for a super sturdy mount. I love to use these vertical connectors :3

(If you are curious about the projector, will open source it soon 🙈)

Closeup of the USB-C receptacle with no cable plugged in. Its opening is recessed in the board, the connector is otherwise invisible. There is a green terminal connector to the left. The board has a lot of ray-like printed structures, a beaker with an orange substance is blurred in the background
Closeup of the backside of the PCB, showing the mechanical connection of the USB-C vertical connector. It is soldered down with three large fillets. It is a very small PCB, hosting the receptacle on its back side
Top down photo of the backside, the USB-C receptacle is also soldered down on this side with two fillets, the board hosting the connector also hosts two resistors

boop 🥺

An assembly of two PCBs, a white one with four large LEDs and a green one at an angle. The leds are initially turned off. A hand enters the frame from the left, booping the top left LED with the pointing finger. All four leds immediately turn on and shine UV light into the camera. The hand disengages for half a second and boops it again, the LEDs turn off and on accordingly. The hand disengages again for a longer bit, followed by a gingerly, short boop, ending the video. There is a plush-snoot in the right top corner of the frame and three more assemblies in the top-Center to left half.

Hardware design is actually all about finding capacitors that match your PCB in color.

Booked an Interrail Pass to travel to #emfcamp, a hacker camp in the UK! #emf2024

Getting excited! 😆 This will be the first time I use the Channel Tunnel!

I would never accidentally be off by a decade when ordering heat-shrink tubing, why do you ask?

Ever wondered if you could use a 3D printer hotend as a fog machine? @vidister and I did, now we don’t :>

A 3D printer hotend on a plastic tablet, illuminated by a white and purple spot. It is attached to a syringe. After a few seconds a hand joins the frame, pressing down the syringe. Immediately a strong stream of fog emerges from the hotend, being glazed in purple light, filling the frame
