We Haecksen love to make cool, fascinating and fun stuff with tech. And so we will at the CFC. Do you already have ideas for our Test Environment?

I recently discovered that diagnostic plugs in cars were more or less standard (OBD2) and that you could buy a plug reader for like 30 bucks. I also discovered that some OBD2 prometheus exporters exist.
So now basically my new project is to have a server in my car, like a RPi. It would srcap the OBD2 data locally and backfill it into my home prometheus database whenever the car gets into my home wifi range.

My partners espresso machine had an electrical fire last month.
Decided to fix it myself and long story short, $65 in parts and a trip to Autozone she has a working espresso machine again.
Makes me wonder if I could help others locally save money by helping them repair things.
Side note I was very happy to see Autozone still has their DEI in place. I checked before going because no company who shuttered DEI is getting a penny from our pockets.
Emil (@greenem) bastelt momentan mit anderen Kindern an einer Tetris-Lampe. So ähnlich wie die bekannte von getDigital, aber komplett selber gebaut, und am Ende soll sie mehr können.
Ein bisschen zum Verlauf seines Tinkering-Projekts gibt es in unserem Forum:

Und wer auch in unsere Gemeinschaft einsteigen will:
Finally finished the replacement of the old 8-bit board with 32-bit v 4.2.7 silent board on my Ender-3. I don't know how does the motherboard affect the silence of the 3D printer, but the difference is staggering. Before it was like a column of tanks riding through town, no all I can hear is the fan ... 
Looking soon to follow with the installation of CR-touch. I really need to step up my 3D printing game, have fallen behind a little bit in recent years ...

10. 10 varieties of flowers?
rev. 4 of cups
rev III. Empress
I am lacking energy today, at the very least. Maybe there will be more flower varieties the next day!
A technical question about SPI. I'm looking at a machine, that has 5 SPI peripherals and a controller. The same CS signal is connected to all of the peripherals.
Am I correct in my thinking that if I would want to reshuffle the devices without access to the firmware in the controller, I'm basically out of luck since it pushes data to all the peripherals with the expectation that the first one takes its piece, forwards the rest to the second and and so forth until everyone has had their share?
Okay everyone... should I blow away my #Pixel 8a with #GrapheneOS or buy a #fairphone ?
FairphoneFairphone 5 with /e/OS by MurenaEverything that makes Fairphone 5 a great choice, now with /e/OS, the privacy-focused Android alternative from Murena.

took few weeks to get back to it, but I routed banksia, now with grove connectors, optional 6 button shape. PoE etc, well.... maybe...
pls feel free to roast my routing, it's weird I'm sure. the 5V/3.3V pours are a bit funky. ground plane not shown. 4 layer boards are fun!

made my first actual useful thing in #FreeCAD today! v1.0 seems to be a pretty huge improvement since I last gave it a go. kudos to all the devs. also thanks to https://www.youtube.com/@BrodieFairhall for the tutorials.
This is gonna be a TPU foot for Comrade the 3D printer, because the paving slab I have her sat on is a bit too small to fit her regular feet.

New video! Replacing the broken fan in my ZD-915 desoldering station and performing some upgrades.

Hey hey HEy I spent today designing and laser cutting a box to fit the fan and filters and adapt to my 75mm pipe.
this thing is gonna work super well! Just put together the box and spun up the fan and there’s so much suction.
Now I just have to buy some air filters. It’s designed to take Toyota car cabin air filters, which are super cheap (literally like $10), rectangular, available with activated carbon media, and fit the fan size great.
The filter will just slot right in the top here (will be the side in operation)
Continued thread
This baby is gonna be the centre of my DIY open hardware soldering fume extractor version 4.
Going to design a laser-cut box that adapts to any generic inlet pipe and fits off-the-shelf rectangular air filters.
Replied in thread
and that'll do for today on the Banksia project.
tomorrow maybe some routing?

I have started another Project…
This time a PCB to throw together a bunch of cheap sensor modules with an ESP32 board and an e-paper display as a little air monitor and misc function box for various rooms.
Temp, humidity, eCO2, VOC, radar presence, ambient light.
with some buttons and an LED on the front too so I can use them as an automation trigger.
Wall mounted, with a nearby USB providing power, because to hell with batteries.
Anyway I need to wrap up some other things before I get to that!
Like filling that hole in the living room wall.
