Engineering

Hey!

I've started this topic because I'm working on a wind turbine ( https://www.thingiverse.com/thing:3091350 & https://www.thingiverse.com/thing:3117435 ).
My main goal is to generate enough power for simple stuff like som LED lighting around the house, charging phones and such (running my printer on it would be an awesome plus though). So here my progress sort of.

I had some decent results as far as speed and torque so I didn't improve my pump one for now, and went straight to the electric one.

I tinkered with the blades a bit already since last upload, also did some extra math to make it work and it should be around 200 RPM with a windspeed of 3.2-3.5 M/S, in the perfect world ofcourse... This, however does not include the lift generated at the end of wings nor the drag.

But still, I'm going on.
I reckon to be able to generate some usable power between 800-1000 RPM, if i can get a motor suitable for it.
I drawn a simple planetary gear that increases 1/3, Printed and just works fine. now adding a 1/1.5 in the end to get at 900RPM (final gear file coming today)

Motor I was Thinking about:

Material:
White PET-G (mainly), Nylon (gears moving parts) PLA ( keep the cost down in non visual/constructive parts.
Carbon or/and aluminum tubes (Blade and general reinforcing)

My questions to you guys,
Is the motor right? Any ideas of improving gear system? tips in general!

I tried looking for RC specific groups but they seemed inactive if anyone has a better suggestion please let me know. If figured a forum of engineers would be able to help!

I want to have a carriage driven by a pulley on a cable or rope (550 para), I have the carriage design, arms and motor mount printed and tested with some old quadcopter parts I had laying around. Problem is the only motor I have is 2605 kv brushless so the thing either screams or doesn't move due to torque constraints.

I am pretty familiar with driving brushless motors with ESCs from a flight controller but other than that I am kind of clueless as to what motor I would need for this purpose. Maybe something related to combat robots that is slow and torquey? I have looked at the car brushless motors and they are still 1500 kv which is still moving really fast.

I have no problem going brushed or geared I just can't find any information on those. I think maybe because in the RC community they are antiquated at this point? Not sure, just trying to figure out how have a slow motor controlled by an RC transmitter! I didn't think I would be this lost lol.

Thanks for any information you can provide,

Elliott

I hope this is the right group for this question: Has anybody tried or has anybody experimented designing and then printing with PLA + electrical conductive filament like (http://functionalize.com) some simple PCB's? If yes, would you like to share your experience, design software used, printer settings, issues, etc? I am fairly proficient with Fusion and S3D (and other slicers). Currently own a modified dual metal head, glass print bed FF Dreamer.

if you want something built or you have a 3d printer you can use the desing and pay group to negotiate price and have something printed or print something or design a nice way to make some money
desing & pay found in the thingiverse groups a nice way to make money

I run a small vacuum forming co. I do a lot of reproduction inserts/blisters for vintage toys like Transforms, G.I. Joe and Star Wars. Each plastic insert I sell, comes with a card board backer. Each blister requires a different size, shape and creased for the card board backer. I know I could buy die for each one and use a die cut machine I am cheap and own numerous 3d printers and was hoping to be able to create my own dies.

Can anyone help me with this project? I’ve added some links so you can see what the inserts, card board backer and my idea are. Thanks for any suggestions.
