Eye See You!

 The eye works!

I printed all the new components which I redesigned and glued it together. I mounted the servo to the back and did some brief programming to get it moving, and it WORKS!! Check out the video below:

A video of the aperture rotating by itself!

I'm so impressed, this honestly blew me away and I just started laughing. I am genuinely shocked that I got it working so well. I was fully prepared to abandon this part of the project and make the eye static, but nope it works perfectly. 

The bad news is, the eyelids are quite complex. I have only just designed the eyelids, very much as an afterthought. Have a look below:

Highlighted in yellow is the lower eyelid and the support arm

I've really struggled with this because the eyelids and the servos and support arms all have to rotate side-to-side with the rest of the faceplate. And I tried several different designs, and they all collided with the centre bar (shown in the foreground in the above photo) when rotating. Either that or they were too flimsy. So eventually I flipped the servos round so that they are pointing out, and that allowed for a much more reliable - and chunky - servo arm for the bottom eyelid. Bad news is, it's only supported from one side, so I've had to make the lids themselves very thin to keep the weight down, so that they don't wobble. That would look rubbish. But the eyelids are printing now - here is Dawn, cracking out the eyelids!

Dawn is my 3D Printer, an Ender 3 v2. She's a good girl, if a little temperamental.

She's already printed the front faceplate:

The white faceplate is quite big.

This will be glued on at a later date, but I want to paint it first I think. It's all very exciting, to see this design come together. But this front faceplate was quite big on the build plate, so I am really concerned at how I am going to print the main body. I'm currently reviewing the model to see how I can slice it up to best print it and fit it together. Currently it isn't going to fit.

I've ordered two more servos for the eyelids so hopefully will be able to get them moving tomorrow!

Hello World!

 Hi all! AmazingOomoo here. I don't know how successful this blog will be. It's my first time doing a blog because my life is not usually interesting enough to read about. But if you are here from Reddit, hooray!! The Background So I love a good project. And often my ideas for project come to me all of a sudden and then I just have to do it. I'm very impulsive. Much like starting this blog, the idea just came to me whilst I was on the toilet. When I am concentrating at work, I tend to put music on, but I find music with words very distracting as I end up focusing on that instead of reading or writing which is what I am supposed to be doing. So I put video game music on. Uncharted, Tomb Raider, and my favourite at the moment - the Aperture Science Psychoacoustic Laboratories album, from Portal 2. Listening to it really got me in the mood to play Portal 2 again, and on my 2nd playthrough I thought "I wanna make Wheatley." I just suddenly had to have one. I have a lo...

An even BIGGER update!

 A lot has changed in the last few weeks! I'm sorry I didn't update sooner. More on this later!! So. From my last blog, if you read it, you will know that I got the EasyVR shield working, detecting my inputs and displaying this on the screen. Well now he speaks!! Check out the below! (You might not be able to see this video if you don't have HDR enabled. Sorry!) Electronics I've really struggled with my EasyVR and my Music Maker shields stacked atop one another, and eventually I ruined my EasyVR trying to change the pinouts. There's two teeny tiny resistors on the back that you can allegedly move and re-solder in order to change the pins that the EasyVR uses. I needed to do this because the Music Maker shield and the EasyVR use the same pins - 12 and 13. (The Music Maker uses several more, but the EasyVR only uses two). But doing this was a bloody nightmare, I don't think I really have the equipment to do it because they're so small, and I burnt the board an...
