Hello Tumblr!

I think it should be finally time when I introduce myself, as I have a big project ahead y'all guys might like (so I'll have something to post about consistently)

There's some stuff I find important about myself:

I go by they/them

I'm a 20 yo, 3rd year student majoring in biotech

I work in two labs: one where we make stem cells to turn them into tissues, and the other one where we engineer med stuff (just got excepted here, really excited!)

I find exciting anything paranormal...

... and thus I am a big fan of related media, from TMA, WTNV and Buzzfeed Unsolved to Ghostbusters (please feel free to give recommendations!)

English is my second language, and I am a novice here, so please be patient with me and tell me if I do something wrong:<

So yeah, I think that's a good start and enough for an intro! I think I'll post something about Big Project a bit later (not that I expect someone to see this soon, but let's keep everything logically consistent).

I expect this blog to be something like an informal lab notebook, but who knows, maybe I'll post something diary-like here as well! So when you guys decide to make a Frankenstein-style movie about my life you could know when everything started to descend into madness :)

Uhhh, okay, that's all for now! Thank you for reading all of this, if you did, and thank you for being here if you didn't! That's okay, the text is objectively too long anyways

Very excited to hear back from you, Tumblr!

Portal's Still Alive melody on Arduino UNO

I was browsing through the internet and found a tutorial on playing melody on Arduino which would incorporate PWM signals to generate sounds. Naturally, I enjoy video games and Portal being one of my favorite. I search for videos and found a video which featured Still Alive on Arduino. The author of the script did some painstaking work on writing a directory of sounds that would make up the music that we are familiar with. 

I will simply show you the step by step process of implementing the code on to the Arduino.

The first step is to get the hardware necessary for implementing the circuit. This is a simple and straight forward tutorial. You only require:

- An Arduino Board (I am using UNO)

- An audio jack or a speaker with 2 wires (one for power and other for ground)

- And a 1K resistor to protect the circuit

You can connect the circuit as shown here

The Arduino pin 8 is used to output the data which goes directly in to the speaker or audio jack.

Here is my setup:

Once the hardware is all setup. Open the Arduino Software>File>Examples>Digital>toneMelody. Once the sketch is opened. copy this code over the existing code. Do not touch the Pitches.h file. That is a library used to generate tones.

That’s all you need to do to play Portal’s Still Alive on your Arduino. Enjoy!

I might use it!

Hi guys !!!

The most important part is the picture, but diary-like log - under the cut if you're interested

I'm not dead, I swear. But the pace of my university and work is moving me closer to that condition every day!

Which is why I've just procrastinated studying for tomorrow physics lab for two hours straight. My professor will kill me, but I've made a pretty picture on my new tablet and that is everything that matters. By the way, this picture is mostly for y'all! It's the one attached. I hope you like it. I certainly do, at least for now.

"But, - you may ask me, - dear Worm! Did you do ANYTHING besides drawing pretty pictures? Are you any closer to being a real engineer?"

Fair question! And actually, I did! It's not much - but it'a a fair work. I've learnt basics - how to make Arduino react on buttons pressing, how to make it light up different diodes; all this stuff. And I'm halfway through a beginners course, after which I can start learning libraries I need for this project. So yeah, I've been busy.

I think I'll write a new post after finishing the course :)

See ya there!

[worm-on-a-sin]

Quick note for myself: clear bird feeder for window glass with camera trap on it (based on infra red motion or maybe ultra sound distance sensor + microcontroller (something like mini arduino maybe?) + camera). Potentially should transmit pictures to some kind of cloud?

Won't tag it yet, have no idea if I'll every make it

Hi Tumblr!

Okay, as I promised, a first Big Project post.

Intro and sentimental stuff

Here's the deal: I have a gf, and her birthday is in June. And I really really really want to make something special. So, fact 1: I have almost unlimited access to electro-stuff. Fact 2: Portal (both parts) is one of her favourite games, and the only of her favourite games I've completed so far.

Combining these two, we get ✨gift idea✨: a paired portal lamp (I did somewhat of a sketch, it's on the attached picture. Unfortunately, it isn't digital, as I do not own any kind of tablet, but I hope the overall shape is still visible)

All of the comments are written in Russian, but I'll translate them below the cut and in future posts.

Anyways! The problem is: it's entirely based on Arduino. And I've never worked with Arduino IN MY LIFE. I know Python on intermediate level, tho, and I've worked with electronics before, so it's not all that new to me.

So, yeah! I'll post updates on my work, so if I manage to get this right anyone will be able to create something like this for yourself and your loved one! From my calculations, it shouldn't cost more than 20 dollars for both of them in currency of my country, but it obviously depends on your location. But if you study in university or know someone who works with electronics, they'll probably give you a lpt of this stuff for free, as it's found easily and in large amounts.

Below is more word-y description of the project.

How it should work

This thing is, ideally:

Turned on and off with 'portal gun' (which is basically a water gun with tech stuff inside). And maybe you can change the mode, turning it into clock, but I haven't decided about it yet

By default, one 'Portal' is orange and one is blue, but through the special server you can change the color of any of this, and the other one will change automatically on the opposite color (for example, if one's color changes to red, the other will be turned green with no manual interactions with it)

In addition, through the same server, you should be able to:

Set an alarm (which will change the brightness of the whole thing at the given time)

Turn it into a clock (I'll describe how it works in a different post, maybe, but there will be no digits or display there)

Refuse the connection with the other lamp and still do all of this things with only your one

Make the other lamp, if it's connected, blink a few times to get the other person's attention

And maybe something else, if I'll think of it later

So yeah, that's the plan! It should be pretty simple technically speaking, and quite cheap at the end. I'll post the scheme and how it will work a bit later, with my Github link for future code. But that's it for now :)

See ya, Tumblr!
