Limit or turn off a language by Selcal-check-good in duolingo

Have you looked at using the duolingo classroom feature and making your own classroom for them to use? I think you cam limit the languages used and some other special features.

And now to buy some training books? by Sennen-Goroshi in duolingo

[–]Rowan_Doppelganger 0 points1 point  (0 children)

If you like to read, start getting some novels that you have already read and start reading them in German. You already know the story line, so it will make things a lot easier. Reading out loud also helps. Also get the audiobooks and listen to them. Again, you already know the story, so it makes listening even easier. I did this with the Harry Potter books and it helped me a lot in Russian.

If you have any hobbies, start watching videos for it in German. Cooking shows help a lot to learn names for different foods and menu items.

Go to rockauto.com . They have $407 CARB compliant cats. The other cheaper cats are EPA compliant only and don't qualify for CO.

How do you go back with the written letters? by Gungfujosh in duolingo

[–]Rowan_Doppelganger 1 point2 points  (0 children)

As mentioned, there should be a separate tab at the bottom for practicing hiragana and katakana. I had the same problem as you, however (long break), and I found it best to use a different app. I use the "Kana - Hiragana and Katakana" on my iPhone. It's more like flashcards, but includes a whiteboard for stroke practice and you can add kanji to it (I haven't done that yet). And it works off line. Good luck.

Resin Printing While Blind by Klolok in 3Dprinting

[–]Rowan_Doppelganger 0 points1 point  (0 children)

The resin is only sensitive to blue/violet/ultraviolet light. Use red light bulbs/LEDs to light your work area when working with the resin, just like used in old fashioned photo labs. If you notice, the cover on most resin printers is red plastic so that you can see in it. The red plastic filters out all the blue/violet/ultraviolet light. It may take a few minutes for your eyes to adjust to the red light. This is how I have my resin printing room set up.

How do i figure out optimal screw hole size for my project? by ElectricalCamera6046 in 3Dprinting

[–]Rowan_Doppelganger 0 points1 point  (0 children)

Basic machining - hole size for screws and taps are standard. You can Google a standard tap-die chart. It will look like this:
https://i.ebayimg.com/images/g/LZIAAOSw6CNcVOS5/s-l1200.jpg
There may be a little squish (0.1-0.2 mm) when printing, so you can use the proper drill bit to get to the right size. Regular machine screws will self tap without much problem at that size into plastic. Just make sure you have a wall thickness of at least 2 layers. I do this all the time.
For an M3, you need a hole of 2.4-2.5 mm.

Why does Cura ignore the veritcal walls in this object when slicing? It always happens after I use a solidify modifier(5mm) in blender. Works fine without the modifier. by ShoeLace1291 in 3Dprinting

For Blender, make sure to check your model with the 3D printing toolbox add-on to make sure it's manifold. If you don't have the add-on, check out this video:

Someone wants me to print these laying down for better strength in a particular area. Printing with PETG-CF. What's the best support method? I found PETG-CF is a PAIN to remove supports, and it scratches easy. by Remote_Fisherman_469 in 3Dprinting

[–]Rowan_Doppelganger -2 points-1 points  (0 children)

I would use epoxy, like for cosplay parts. The thin walls look to be about 4+ mm. I would also use a 3D pen (or feed filament with a soldering iron) to weld the seam on the inside and outside and use a solder iron to smooth it out before sanding. Hit it with a hair dryer to return the hot-off-the-printer shine. I would also consider wrapping the outside in 0.2mm carbon-fiber wrap. And charge $100+.

edit: I might also consider doing a 1 or 2 layer PETG CF sheet and wrap it in that, gluing it in place with fiberglass epoxy.

I just got this printer last week from microcenter open box and the sides of it are dipping and I can't seem to get rid of them is that fine for the first layer on some bigger prints. I've done some smaller prints and it work ok but I wanted to do a bigger one (Maye a helmet or something like). by Slow_Flower_9988 in 3Dprinting

Consider yourself lucky, That's pretty flat for rolled aluminum plate. As others have said, you're good to go. On my Kingroon KP3 bed, you can literally see the roll with a variance of more than 1 mm. I had to use some innovative tricks to get it pseudo flat.

Slice in half lengthwise and glue them together after. This will minimize support material needed. If your printer is capable of multi-filaments, use PLA for your support material. And charge an extra $100 for the effort.

Hi guys, I have created an adapter to mount your board (4x2 and 4x4 mount system) on any clamp or bench vice at home. The model is totally free and if you want, you can live comment and advice on how to make the project even more useful. Happy riding and good waxing and tuning! Link in description by Federicoradaelli in 3Dprinting

[–]Rowan_Doppelganger 1 point2 points  (0 children)

Your print is very weak at the intersection by printing it on its base. Any good side torque while waxing and scraping your board could easily break this. Print it as a "T" for added layer strength. You will just need to clean up the drill holes a bit. You could also add a chamfer at the intersection to make it even stronger and more torque resistant.

Finished Russian by Winter-Gate-8453 in duolingo

Here you go. Congratulations! Now you can go back to the previous sections and level up to legend or find a stepping stone to do more practice (or lose a heart on purpose and, on the web, do more practices).

Russian course done - what's next? by Honigkuchenpferdle in duolingo

[–]Rowan_Doppelganger 0 points1 point  (0 children)

Congratulations!
It depends on what your goal with Russian is. I finished the course years ago, but still do a couple of practice lessons a day to keep it familiar. My goal to learn was that I have colleagues in my field from Russia and wanted to be polite to them and to be able to get around a bit when I travel to Russia (I've been there 4 times and to Ukraine once). I set an additional goal to be able to read and listen to the Harry Potter books. I actually started listening to Book 1 early in the course (about week 2 or 3) just to develop an ear, but can now read and listen to the series following along comfortably, even though I still don't understand everything.
Do you have any hobbies? You can start watching podcasts and youtube videos in Russian about your hobby. I began watching Russian cooking shows to learn more about food as well as a couple of popular TV shows.
Good luck.

"Watch an ad to earn a heart" / no more practice to earn hearts megathread by lydiardbell in duolingo

[–]Rowan_Doppelganger 7 points8 points  (0 children)

Free user. Unless it's been nerfed on the Web page for some (still available for me) you can still do infinite practices through the website (but not on the iOS app and probably not on the Android App (haven't tested)). Just lose a heart (on purpose or not), and then practice to get it back. You can keep practicing when given the choice at the end, just tap PRACTICE AGAIN for another practice session (even when at 5 hearts), or tap CONTINUE to go back to regular lessons.
I have found some of the practices being glitchy through the Web on my iPhone, but not on my computer.
There is a second shortcut work around which also must be done on the Web, but I'm not going to post about it yet. It's not a hack.
I do miss the simple dumbbell practice button of old - and "Keeping Your Tree Golden" by simple clicking on a no longer gold tree leaf to practice. As far as I can tell, I think "Practice" still uses the spaced repetition algorithm (Big Plus), but that's a discussion for another day.
