  • First off, it looks good as it is. Well done! Also, it works and that’s the important bit. Some things which help me:

    • use equality constraints instead of repeating measurements for radii and lengths
    • fillets can be added after creating the main shape, this simplifies the sketch
    • if you know this will be mirrored, draw a quarter and mirror the extruded body in part design (you could use multi-transform here)
    • use formulas, spreadsheets or reuse named distances if you want to change things later
    • make extensive use of the Part Design workbench but sometimes dabble in another workbench because when they click you’ll unlock a new set of combinations and turn FreeCAD into a sort of swiss army knife

    Congrats on your first model 👏



  • It is similar in its out-of-this-world feeling but vastly different in what it aims to cover. Both feel like impressive tools from different timelines.

    Vim is a text editor heavily focussed on efficient modal movement and text editing. This gives it some weird keys to press but it’s very efficient in manipulating text. NeoVim seems more extensible than Vim but I have no experience with it.

    Emacs is more like “a system for augmenting the human intellect”. It is a Lisp interpreter which allows you to change the system to your needs. Emacs often predates other tools and so default keybindings and naming are often good but weird. It treats most of what it supports as text so it feels like a text editor from a distance but aside from coding and writing prose, you can use it as a mail client (mu4e, gnus, notmuch), to browse the web as text (eww), as a second brain (org-roam, denote), to play Tetris, as a chat client (erc, ement.el), it can even be a window manager (exwm) and much more. It’s like a suite of applications, maybe?

    Vim users gradually try to get Vim keybindings into all of their applications for fast text editing. Emacs users try to pull everything into Emacs so they have a fully programmable and consistent environment for all their work. A cozy space. Although the debate never cleared on preferred keybindings of Emacs vs Vim, evil mode does bring Vim keybindings into Emacs. Both have a steep learning curve and last you a lifetime.





  • There is a standard connector which existed before big screens landed in cars, the OBD2 connector. Dongles are cheap and you can read the output from your phone or computer. Some dongles support bluetooth. The connector is mandated in some markets and I guess that makes it less interesting to add a redundant interface inside of the car. It’s fun to try if you’re interested. Manufacturers can extend the error codes IIRC.

    Tesla has a service mode on the display through which you can scan the car for faults, run a battery test, … It is password protected but the password is publicly available.





  • I run e/OS on a FP5. I ran e/OS on a Essential PH-1 before and going back to a phone with Google installed just didn’t sit right with me. I did not feel like I could trust the device even after trying to toggle as much of the creepy spying off. As if there’s still someone probably looking over your shoulder because you configured something wrong.

    It is not perfect, but it is easy to use and full-featured. All regular apps feel great and battery life is good. I still use specific Google services (such as the calendar for work) but no specific Google apps. I guess Maps is the biggest challenge now but alternatives are good enough to get around with.

    You can run Android apps. Not sure about payed Android apps. I try to install FOSS apps through the integrated f-droid store if they’re available there. Installing app store apps sometimes fails because Google blocked the installer. I could install everything so far when needed (including banking apps and specific apps for the vacuum cleaner and such). Sometimes the Android app store apps don’t update for a while and I don’t notice.

    I don’t use Murena’s services but self-host Nextcloud. Based on the information they send I think they’re doing a great job for their size.

    I flashed the FP5 myself with a beta of e/OS when it was just out because the other phone was broken and (again) I did not feel right with the spying demon in my pocket with native Android. You could flash your device too.

    It’s comfortable on this side. If you have further specific questions, shoot.



  • It’s very interesting to scroll through and I could easily find my way in it. It is also very fast. Thank you for sharing.

    I have the tendency to lock everything in place and fixate it based on some logic. For example: I would constrain Sketch010 for PocketGlandHoles so each of the holes is exactly the same distance. Lack of experience makes me want to have a parametric model so I can move things around until I make up my mind. Looking at this file however, it may be better to just model again when things change.

    I’d love to have another peek if you screw up with this approach or if you’d have a finalized version.


  • I’d love to see the FreeCAD files and possibly see the progress too. Looks like a good project to learn from.

    I’ve only seen my own (sometimes messy and slow) FreeCAD files and I also don’t get round to publishing anything either. Last time I made an enclosure I made a mess where it became slow because a lot was recalculated based on the position of the components and it had some curved surfaces. I do remember making clips (did not work well) and a ridge (that held up a bit better). Would use screws next time like you’re doing here.
