BUILDING A HOVERCRAFT #3 - DOUBLE IMPELLER!

To reduce the torque needed on the motors I switched to smaller impellers and a double impeller configuration. Each impeller blows in a different chamber inside the chassis so the efficiency is not reduced. Unfortunately, with free time I made two mistakes, one trying foam inside the front part of the chassis, the other one, the inner tube skirt, that thing is too stiff. Next week I'll try to improve that, even if it is not the definitive solution as I'm planning on putting a finger skirt on this thing.

In case you want to know the hardware use in this episode:

ZOP Power LiPo Battery 11.1V 6000mAh 3S 35C

RC Quadcopter Propulsion System - EMAX RS2205 Motors + LittleBee 30A ESCs + Propellers

 

I've been able to keep the weight and plastic amount down on this one, so I think this will be a great project for anyone with a CR-10 or similar to try once it is finished. 

 

I'm still planning on releasing the Fusion360 files once it is done.

This project is requiring almost all my printers every week. If you are interested you can check them out here:

CR-10 - A reliable workhorse.

Anycubic Mega I3 - The Ultrabase is like magic

CR-10 Upgraded

Tevo Tornado 2017 - Really impressed about the hotbed, things really stick to that.

I hope you enjoyed the video, Thanks!!!

 

 

 

BUILDING A HOVERCRAFT #2 - PRESSURE!

In this installment of what it seems to be a series I switched from the propeller to an impeller to see if I can get any pressure on that air cushion. It seems that I mounted the propeller backwards on the first episode and that is why it didn't work in the first place, but this impeller thing is too fun to let it go, so I'll keep on trying to see if I can make this work properly. The motor and the ESC where working too hot because I was asking for too much torque on that little motor made for speed. Next week I'll try to amend that.

In case you want to know the hardware use in this episode:

ZOP Power LiPo Battery 11.1V 6000mAh 3S 35C

RC Quadcopter Propulsion System - EMAX RS2205 Motors + LittleBee 30A ESCs + Propellers

 

I've reduced greatly the amount of plastic on this thing, everything is now a hollow hull with nothing on the inside. All the walls are 1.6mm thick by design which makes it very light in the end. 

 

I'm still planning on releasing the Fusion360 files once it is done.

This week again I've used almost all my printers to make this project because of the amount of parts that I needed, If you are interested you can check them out here:

BUILDING A HOVERCRAFT #1 - LEARNING

I've been asked a lot to make a hovercraft so Gearbest sent me these so I could do it. Those are very nice little motors and work great so If you feel like it, take a look here:

ZOP Power LiPo Battery 11.1V 6000mAh 3S 35C

RC Quadcopter Propulsion System - EMAX RS2205 Motors + LittleBee 30A ESCs + Propellers

 

I've spent around 70€ only in plastic in this project but this thing could crash into a wall and the wall would break, I need to redesign everything so it is much lighter. Also I'd like to do it in only one piece. I've realised that I need much less space Inside than I previously thought so I think I can make it smaller but still powerful. It'd be great If I could do it so anyone with a CR-10 or any other printer of similar volume could print one. 

 

Before anyone asks, I'm planing on releasing the Fusion360 files once it is done because it'd be great to see people making one of these. I think I can make a good enough hovercraft so, we'll see. 

This is how the thing should have looked like if this design worked. I had to put this here before I delete it in an iterative design frenzy.

#8.9 CABLE CHAIN SUPPORT - BUILDING THE BIG 3D PRINTER

I've received many complains about that cable chain hanging hunky dory, so I've devised an insurmountably clever solution, behold the cable chain tray!!

IVANMIRANDA.COM TRAILER

A small trailer I did for my channel, you know, because you have to have a trailer...

#2 THE STRUCTURE - BUILDING THE BIG 3D PRINTER

In this one I show you the basic structure with which I plan to build this printer. Something like this is what I use in other projects based on the same profile.

#1 HISTORY - BUILDING THE BIG 3D PRINTER

The first chapter of me ending up building a large 3D Printer from scratch. I hope you enjoy this series as much as I did.

IOT DRILL PRESS CONVERSION LIVE VIDEOS

This is my first attempt at a live video with a not so successful ending but a very fun thing to try. Here I leave all the separate videos because the stream kept being interrupted because I forgot to switch my phone to wifi... yep.

IOT DRILL PRESS CONVERSION

I converted my drillpress to do a little realtime online game, what could go wrong with an IoT drillpress?

DIY BIG DIGITAL CLOCK

Using the neat WS28912B leds and an esp8266 I made this 3D printed digital clock. It is a tad bit more than a meter wide and it sets itself on time via the internet. It connects to a nist server on the internet and requests the time to the server, neat uh?

MECHANICAL FLIP-DOT DISPLAY

As weird as it sounds, this is a dot display where every dot is moved by a servo which flips it 180 degrees. Each dot is white on one side and black in the other. This is good for nothing, it is not scalable nor useful but it has been lots of fun to build.
