Hiding christmas calendar gifts in the garage, then letting the kids figure out my #3dprint hints

Funny how I seem to have forgotten the good ol' scale #modeling kits with glue and sprues. How about combining #3dprinting and glue, to get the best of two worlds: #3dmodel whatever you want, and don't worry about printer limitations.

Nerd tip: Stumbled over some third party #printable shrink tubes for my old #labelprinter and gave it a shot. Turned out to work wonders. It's just about perfect for #electronics #prototyping #breadboard #esp32 #shrinktubing All wires neatly labeled with signal names from the #schematics 🤩

If all you have is a #3dprinter then everything begins to look like a #3dprint job.

Did a angled mounting adapter for a closet rod in #freecad #qcad ...

Project weekend! PCB part placement in #KiCAD, alignment of the assembly in #QCAD and step-to-dxf exports in #FreeCAD.

My front panel "hat" for a #raspberrypi 5 is coming along.

Done! You can get the model as a STEP file on my GrabCAD profile: https://grabcad.com/library/usb-a-connector-b13-7-vertical-1

Advancing my #FreeCAD skills. This is the hardest #3D modeling challenge I've taken on so far, using the sheet metal workbench to create the shield for an USB connector for a #KiCAD #electronics project.

Gotta say, this was one of my nerdiest debugging sessions in a long time — it ended up in my #electronics lab.

Sometimes, setting breakpoints and inspecting variables just doesn’t cut it.

When something’s off with the #i2c bus on a #raspberrypi, all bets are off until you break out the hardware tools.

The oscilloscope solved the mystery instantly: an overly long delay between writing the address and reading the target register was causing the peripheral to time out.

Planning to use a #raspberrypi as the primary processor in your next #electronics project? I just discovered that there are loads of handy interface extenders out there.

They let you place sdcard slots, RJ45 plugs and USB ports anywhere you like.

So, no need for premade enclosures that hardly ever fit your exact hats and needs.

A dust pan only has one single job. Still, it must have been far too complicated for whoever designed this one, so I had to amend it. Now, the dust ends up INTO and not UNDERNEATH the pan 💪 #DIY #3dprinting
