A VERY FAST MARBLE SORTER

Hi everyone!

After the last video I got tons of suggestions to build a marble sorter and here we are. I would suggest you to try and guess how fast do you think this end up going before watching the second part of the video.

I must say that I had a contingency plan to make the "se...

A MARBLE CLOCK THAT (DOESN'T) DISPLAY SECONDS

Hi everyone!!

I've been fighting with the new marble clock a lot lately. In the rush of the moment, printing recording, assembling... is quite hard to realize what's actually going wrong and this video is a great example of that. After the last video I thought everything was A-ok and ready ...

BUILDING A MARBLE CLOCK THAT SHOWS SECONDS!

Hi everyone!!

Is evident that I lost my marbles and now I want to do it faster!! I'm trying to build a clock that can update every second and that, I can tell you that that comes with its own set of hurdles. 

At this point I'm pretty sure that there's someone out there with the j...

BUILDING A MARBLE CLOCK PT4. - NOW FASTER!!

Hi everyone!!

As I promised in the last video I tried my best to make the clock update minute by minute. It wasn't an easy feat as I dealt with many (expected) issues. As many of you will notice I'm still having lots of issues with the marbles getting stuck on the machine as there's about a...

BULDING A MARBLE CLOCK PT 3

Hi everyone!!

It took a while indeed but it works!! The "small" issue of the marbles getting stuck everywhere brought me to do one redesign after another which in the end took me to reprint every single piece on the machine but at least it solved the problem. In addition to reprinting every...

3D PRINTED MARBLE CLOCK PT. 2

Hi everyone!!

What was going to be a two video project seems that its going to be a three video project. I managed to get the marbles sorted and to display the time but marbles are marbles it seems and they get stuck here and there when I try to change the time so I'll need to make some "mi...

3D PRINTED MARBLE CLOCK PT.1

Hi everyone! 

I've always wanted to build a marble clock, in fact, I have quite a few design ideas for making one but I chose this one because I thought it was the easiest one (insert facepalm here). 

I decided to upload it as a two part video because it was taking forever t...

GIANT ROBOTIC HAND

Hi everyone!!

I guess once you have a few giant 3D printers building a giant rideable robot is just one step away, right?

I've been tempted many times before to build a giant robot that I can ride and this could be the first step. A giant robotic hand that I could put on the robot to ...

I MADE A COPY OF MYSELF

Hi everyone!!

The second part of the giant 3D printer is here! 

On this video I make the bed frame and the bed heater and put the printer to work with a scan of myself. I had a blast with this one and printing myself was definitely funny. 

Please enjoy the video and as...

I'M BACK!

Not that I knew that I was going to be away for this long but anyway...

I've been working on a new giant printer build for the past three months and this is the video of the first part. 

I started this build because lots of people asked for the files of the previous giant printer...

GIANT 3D PRINTED RC EXCAVATOR BUILD PT.2

Hi everyone!

I finished the excavator at last! This thing is lots of fun and very fragile. I, again, went too far and this thing is too big for this kind of design. I recon I could try a different design using the blocks to make an excavator at this scale that doesn't "autodisintegrate". 2023-02-14 14:55:37 +0000 UTC View Post

TESTING THE MIRANDA MINI BLOCKS WITH AN EXCAVATOR

Hi everyone!

Trying to build the Go Kart to race Matt Denton found a lot of flaws in the design on the blocks but I found even more things that could be improved. I had built the "mini" version of the Go Kart but I needed something with more "engineering punch" to do the final test to the d...

LEGO INSPIRED GO KART PT.2

Hi everyone! The second part of the Lego Inspired Go Kart build is here! This time I focused on the Miranda Blocks design and tried to make more sensible progress by testing the Go Kart Design with the newly created Miranda Blocks Mini. 

There's still a bit of work to do on the Min...

LEGO INSPIRED 3D PRINTED GO KART PT1

Hi everyone!

Last spring I tried Matt Denton's 3D printed Go Kart at Makers Central and I loved it so much that I challenged Matt to a race. He accepted so I have to make one now. 

I've been wanting to make my own building blocks for a long time and this looks like the perfect pr...

AT LAST, A 3D PRINTER WITH COREXY KINEMATICS

Hi everyone! I kept doubting until the last minute while designing the printer but in the end I caved and went for the corexy arrangement on the XY axis belts. 

It was easier to implement than I thought and harder to understand than I anticipated. I had to even make a prototype to wrap...

A 1 SQUARE METER BED FOR THE BIG PRINTER

Hi everyone!

The Big 3D printer build continues and the next step was to assemble a heated bed to go on top of the bed frame that I built in the last video.

I decided to swap the mirror for a glass as I wanted to give it better looks and also to be able to show the four squares where ...

BIG 3D PRINTER BED FRAME WITH POWER!

Hi everyone!

In this second episode of the new big printer build I added the bed frame and the z axis motors and belts.

I was already worried about the rigidity of the frame and after reading all the comments I knew I had to do something about it so I added cross braces in three of th...

THIS TIME I ALMOST WENT TOO FAR

Hi everyone!

This one has been in the oven for a very loooong time, and it is finally time to bring it to life. This one is new 3D printer is going to be huge! The planned print volume is 1000x1000x1420.

It is going to have a moving gantry on top and the bed will go up and down. I'm s...

3D PRINTED DESKTOP CNC ROUTER

Hi everyone!

After using the Tiny CNC that I made back in January for a while I've been wanting to improve it and make it more rigid. The natural next step for that router would have been to machine the plastic parts in aluminium but I was sure that the rods and bearings were way more impor...

BIG 3D PRINTED TANK FIELD TEST

Hi everyone!! I've been doing a lot of work on the tank to get it ready for this field test. I think it looks very cool with those lights and I'm really happy about the new control panel, it does everything that I need. I wasn't that happy with the pedals that I designed a few months ago so I did...

The Giant 3D printed tank got a hopper!

Hi everyone! 

After getting the cannon working it was time to add a hopper to truly see what the fire power of the tank is. As you can see in the video it was an eventful process as I got tangled in a few improvements that even though weren't strictly related to the hopper, They made t...

THE ALGORITHM OVERLORD

Hi everyone, I've been talking recently with some savvy friends about Youtube performance and we've got to the conclusion that that dip at the end of every single one of my videos is making Youtube recommend my videos less than it should. (That graph shows how much people watches every second of ...

THE CONTROLS FOR THE TANK TURRET

Hi everyone! 

I'm right now recording the video where I install the hopper on the tank turret for an insane fire rate but I wanted to show you a peek into what's coming next for the tank. 

These are the first and second iterations of the design and as you can see I added not...

3D PRINTED TANK GETS A CANNON

Hi everyone!

The Big Tank project is picking up speed! I keep underestimating how much work is to make progress on this beast but I'm enjoying every second of it. In this video I added the cannon (at last) and added the tilt mechanism and the ball conveyor and ball revolver that feed balls ...

THE GIANT 3D PRINTED TANK GETS A TURRET!

Hi everyone!

After three years of waiting the end is near! In this last video I made a turret for the tank and made it spin very fast! Hopefully in the next video I'll be able to put a cannon in it so we can launch some balls. 

In this video I try a couple of things that I've nev...

I TOLD YOU I DIDN'T FORGET

Hi everyone!!

I finally got back to the big tank project! This was more fun than I even remembered.

Many of you may remember that the tank had a clamshell style cover, and it seemed like a good idea to me at the time but it had two 30 Kg gas cylinders to help with the lifting and thos...

3D PRINTED DESKTOP CNC ROUTER

Hi everyone!!

I wanted to try a few new tricks so I designed and built a new 3D printed CNC router. I also wanted to add a really small one to the line up that doesn't weigh a million tons as the CNC mill that I remade in steel weighs a ton, it weighs so much in fact that for now I can only...

I MADE AN ELECTRIC GUITAR THAT CAN'T BE PLAYED

Hi everyone!

In this last video of 2021 I built an electric guitar for the marble music machine. I got good advice from Carlos Anjuda from Anjuda Guitars the same that made the CyberBass for the MMX. 

The design is very intentional as I'm planning on automating the chords with a ...

A MARBLE MACHINE BUT PROPER SIZE

Hi everyone!

After the last marble machine video I started trying to figure out how to better solve the issues that I had already found and one thing led to another... and now we have a big marble machine.

The top half of the machine is just a place holder for a future structure (TBD)...

I MADE A MARBLE MUSIC MACHINE (for real this time)

Hi everyone! 

Do you know when you're sitting at your desk, you get an idea and think is going to be a week, two tops? And then you start designing and that alone takes a week and a half, and then printing everything takes another two weeks and by then you just are two far in to quit? ...
