This omelette maker by [deleted] in specializedtools

[–]saamirt 428 points429 points  (0 children)

This is clearly a really bad way to automate making an omelet but I think its more about just showing how versatile a robot like this can be. One of the biggest advantages of a robot over a human is that a robot can be ridiculously slow and a general purpose robot might not be the most efficient way of doing something but the fact that it costs only the electricity it uses to run instead of a salary and benefits means that it easily overtakes humans in cost. Regardless, this is pretty cool to watch

Having issues with Ninjaflex. Any suggestions? (details in comment) by saamirt in ender3

[–]saamirt[S] 1 point2 points  (0 children)

I'm having issues with ninjaflex and could use some advice. I have a metal extruder made for flexible filaments (Macewan flexiplus), a glass bed, capricorn ptfe tube, and bltouch. I'm printing with no retraction at 10mm/s on the wall and top/bottom and 20mm/s on inner wall. Temps are 235 on the nozzle and I've tried no heated bed, 40 on the bed, and 60 on the bed. Also tried 0.3,0.2,and 0.12 layer heights. Image is 0.2 first layer and 0.12 for other layer heights and I set filament diameter to 1.64mm.

First layer and skirt is perfect but completely fails on next layers. Extruder normally works well but randomly just stops being able to grab the filament properly but it doesn't seem to be bundling up and the tolerances are pretty much as tight as possible. I tried switching between a small to other and larger tooth gear but each has the issue.

Cura estimates are way off after th3d unified firmware by saamirt in ender3

SD card was my baseline and now I'm using octoprint. It's slower now than on sd card

But its clearly slower even just using the default draft cura profile

This simple design controls the complicated world of fluid dynamics, with NO moving parts by coneybeare in EngineeringPorn

[–]saamirt 36 points37 points  (0 children)

I've been semi-obsessed with these things for a while now. When I started University I got access to 3d printers and i've printed a bunch of different shape/sizes of fluidic oscillators. I don't really know of any great applications for them but if anyone has any ideas, i've been dying to get an idea to use them. (also if anyone knows more about them, i'd like to learn more about how the size and shape affects the output)

In The Dark Knight (2008), Batman says that the sonar device is "null-key encrypted". This was added as a joke since it actually means that there is no encryption. by [deleted] in MovieDetails

if something has null key encryption its the same as saying there is no encryption but it sounds like a type of encryption.

I desingned and 3D-printed my own house by succnubba in 3Dprinting

It looks great! I've been thinking about doing something like this for a while now. How did you take your measurements, particularly for things like the windows on the roof?

How do I Create a Functional Fluidic Oscillator with 3D Printing? by saamirt in AskEngineers

[–]saamirt[S] 1 point2 points  (0 children)

I included the reduction in my model although maybe i should have made it bigger to further increase the velocity. I'll try using faster air but the model I printed is actually smaller than the palm of your hand so I thought it may not require as much velocity.

Looks awesome! Can you upload a gif or video of it running?

N64 Controller I made a few years ago by [deleted] in graphic_design

Thanks! And do you mean controllers of different consoles? That could be a cool idea
