Hello! If you want to build your own 3D printer, look at the RepRap project: https://www.reprap.org/wiki/RepRapHowever, you do not need a 3D printer to recycle paper! You can make molds out of wood or clay even!

Awesome work! Thanks for sharing

Whoa!! Fantastic work, thank you for sharing. I'm so happy to see people picking up the project.I love the idea of the badge! Lets you have plastic-like forms and detail without polluting the environment after its single use.

I'm sorry to hear that!! I used an old blender from Cuisinart.

Yeah! You could probably apply a thing layer of wet pulp around a simple form (maybe a cone for potting plants) and slide it off once dry.

This is a fantastic find! Thank you so much for sharing.

Thank you for pointing that out!

Embedding seeds into the pulp objects would be awesome. Once your done using it, throw it in your garden and watch flowers sprout!

I haven't looked into casein, thanks for the tip!

Well said! I completely agree

Thank you! I'll be sure to check out rosemary oil, didn't realize it was also a preservative

Thanks Becky!

Thanks Becky!

Thank you! This is really insightful. I'll be sure to experiment and try that.

Thanks Becky!

The servo horn comes with the servo I linked!

Thanks!

Thank you!

Thanks!

Thanks!

Thank you!

Thanks! With grippers, the holding strength is more important, however I haven't measured this.

Thanks!

I guess it could be ¯\_(ツ)_/¯

Thank you!

Thank you, that may be a future improvement.

Thank you!

I designed this in 123D Design and printed the molds on a MakerBot Replicator Mini.

Thanks!

Thank you, but I'm not sure what you're talking about. Changing the durometer and air pressure can deliver more force, but with a given actuator, there will always be a consistent pressure-force curve. If I were to use a hydraulic fluid, it would transfer more force, but durometer and pressure would still have the same effect.

I like your idea, but there are a few issues with it (besides the fact that it's just not what I wanted to make). Firstly, if I were to restrain a balloon with a rigid frame, then it would not be a fully soft robot. Secondly, your idea would make it difficult to make an actuator that does anything but just inflate, as the rigid frame would forbid it from bending or extending. Lastly, although restraining wireframes sound like a good idea, the inflatable tends to inflate in all other directions, making it not so useful for restricting movement. Typically soft actuators with restraints have restraints surrounding them completely. Hope this clears things up.

Not very much point to it, it probably wouldn't improve it that much. I don't know what your refering to as "weird horizontal rotation" either. The holes in which the string runs through functions as a form of a pulley, so the motion is well allinged already.

I just said that in the previous comment.

There are a few possible limits to how many valves you can have. First off is power, you typically don't want to pull more than 1 amp through any Arduino. I'm not sure off hand of the current draw of the valves. The other limiting factor is control. You need enough pins and motor drivers to control all the valves. The best advice I can give for learning electronics is how I learned. Just build stuff.

No problem! Questions are how you learn. To have multiple controllable outputs, yes, you would need to add more solenoid valves. I apologize for the noise in the background, that was my 3D printer, not the pump. When running, the pump is not extremely loud, I can't give you an exact number however.

Exactly, unless you are using the check valve, in which the air is automatically kept in.
