We're a little crazy, about science!

Neuralink: Beyond the hype

The sewing machine like robot that is the linchpin for neuralink.
The sewing machine like robot that is the linchpin for neuralink.

Brain machine interfacing, as someone who does research in the field and is getting a PhD in a brain machine interface lab, I think I’m qualified to comment on the progress neuralink. There’s a lot of hype out there, curing disease, ending paralysis, a world where we are part of the machine and the machine is part of us. Is it science fiction, or is there more to it?

Fact or artifact

Does it belong in a museum though?

A new turn in the saga of my data processing. There has been some concern that the artifact from the stimulation is causing the thing I am seeing in my data. There are arguments to be made for both sides, but let’s go over what that could mean for me.

Path planning

One would think that the pandemic would put a lot of things on hold. Unfortunately (here in the US anyway) that isn’t the case, it just makes things harder to do because everyone expects you to perform at a higher rate now that you’re not commuting to school… how the hell that works is beyond me.

So much data

This has basically been my progression in this project.

Well I’ve processed (poorly) about half of my data. Now, when I say poorly I just mean the visuals for it are garbage and I need to tweek the sizes and things to make it look nicer, but the idea is that I’m more interested in finding something than I am in making it look pretty. I’ve processed two of four of my subjects and well I’m excited!

The after

I’m trying to remain calm. I am an objective observer in the world of science and whatever the result, I will NOT let it cloud my emotions. I am neutral and I will remain that way… oh who am I kidding, I DID IT! Two years of planning and convincing people this would work. Then last night I had my first result, and it was a relief. It was a small step, but one I was afraid the data wouldn’t let me make.

Into the unknown

Time to cross that bridge…

Today is going to be a somewhat anxious day for me. It’s the day I get to crack open my data and see what spills out. There was a process to get to this point of course, it took me about a week, but today with just a few clicks I’m going to see if I have something or if my idea was never meant to be.

How to 3D print… yourself!

It’s hip to be 3D…?

Ever have an MRI or a CT done and thought, “I really wish I could do something with that.” Well you’re in luck! Today we’re going to do a quick rundown on how to take a medical scan and convert it to a workable 3D model. Something you could 3D print for example! As with everything else I do around here, this is done with free software so the only limitation is your access to medical scans, but we can get into a work around.

3D Print… yourself!

It’s hard to tell the scale from this image, but you’re looking at a full sized copy of my spine. Yes, full sized as in big, really big!

You know what’s boring? Going to the doctors office and getting an MRI. You sit there forever! Of course a CT scan is faster, but there’s still a lot of waiting involved and in the end, you get to see a quick glance of the images captured if you’re lucky. Where’s the fun in that? Well I’m here to help you do something with that information. Useful? Maybe. Fun? Definitely!

School is coming…

3D printed spinal column still in parts getting ready for cleaning and assembly.
Did I mention I 3D printed my spinal column (as in a copy of MY spinal column)? Because I did. I’ll post up an explainer how later, but here it is in pieces waiting for me to have a few free moments to clean and assemble it. In the meantime, this is the teaser image for it.

With classes about to kick off I’m left wondering what will be different for me. This term I’m doing the safe thing and taking a single online course. The rest of my time will be focused on my research and doing what I need to do to be ready for my PhD proposal defense (the step I want to take this fall term. So what am I doing to get ready?

School and COVID-19

School being cleaned in preparation for students return. This is security theater, it spreads from student to student more readily than from desk to student.
This is security theater, like taking your shoes off at the airport, it does nothing to keep you safe. Instead it makes people feel better, in this case the school for letting your children spread this virus without a care.

School, I would like to consider myself a lifelong student, but formal instruction is a little different than learning on the job or via the web. With classes starting, my stress seems to be slowly ratcheting up. Oh I’ll be fine, I’m taking an online course this term, I’m worried about everyone else.

A busy day!

Yep I use this image a lot, but it’s such a great representation of our labs work!

Well I didn’t plan for it, but today is a busy day! I’ve got a lot going on at the moment so not a lot of time to write. Let’s just talk about what I’ve done and have left to do so I can get back to it.

(more…)

Process the data!

This is what raw EEG data looks like. Seriously, it’s a bunch of squiggles. However, we can make sense of it and we can even write some code to make sense of it in real-time so you can control things with your brain!!! <EVIL LAUGH>

It’s a process… that’s for sure. So you’re a scientist and you collect a ton of data, well now what? We’re talking about me of course. I did it, I collected a ton of data and now I need to do something useful with it. This is the part I wish I could skip over and get to the part where I get all the cool results, but I guess we’ve all got to start somewhere.

A new chapter and a look back

We’re looking forward today… while looking back too. I did a big thing! I finished my 365 days of academia goal, it felt too big to do, but here we are. So what’s next? Well we’re going to talk about where we are, where we were, and what’s coming, so let’s get to it!

The end

I fully and completely wanted to die. I like starting stories of my life off that way so you set your expectations low and your pity high. I wanted to die and I tried to kill myself the best way I could think of, obviously it didn’t take. Today is the end of my 365 days of academia project and I feel like looking back, way back. If you feel like reading a super depressing tale, then this is for you!

Day 364: The lazy goals

An old photo, but one that I think came out nice.

Awhile back I made some goals for myself. They weren’t your normal everyday kind of go get em’ goals, they were what I call lazy goals. That’s right as a full grown adult I reserve the right to have lazy goals. I even check them off on a list, seriously. You should too, it really does help remind you to take a break.

Day 363: Solid Modeling – Week 10

Dancing tree

This has nothing to do with today’s post, it’s just the most cursed thing I’ve created in SolidWorks.

All good things come to an end. It’s week ten and officially our last post in this quick run through. As always we use FREE SOFTWARE to do this, so if you’re just joining in you can find the  full course in the Solid Modeling for Beginners category and you don’t need to spend money to learn. Since this is our last post I wanted to do something a little different today, let’s get started!

Day 362: Experiment two

Just a giant case full of the equipment I borrowed from my university for experiments. Pretty sure the school’s office staff thing I was robbing the place though.

Well today is going to be a quick recap of my experiment yesterday. This will be just as much for me as it is for all of you. While I can’t go into the experiment details (since I’m working to publish this) I can give a pretty good overview like I did the last time around.

Day 361: Accidental history

Impostor syndrome
Art by: xkcd

Ever wake up one morning and realize you’re exactly where you wanted to be. That you’re in a place you never even dared to dream you could reach because, well it was silly to think you could accomplish something like that. Dreams that big weren’t meant for people like you, so you didn’t even bother to think you could get there. Yet… here we are.

Day 360: Second experiment

Computer

The computer I use to process all my data, even with this it takes FOREVER to finish processing.

Well tomorrow is my second experiment. To be clear, it’s technically the same experiment, just a second person, so maybe it would be better to call it trial two? In any case, while the last one went (mostly) well, there are a few things I’m changing to make this next one even better. Sometimes when you prep for an experiment, you don’t realize what you’re forgetting until you can’t do it, so we’re correcting that this time.

Day 359: Car problems

Engine

Thought it was the PCV valve, but nope…

Well if things weren’t bad enough as it is with my own little world, we get to add car troubles to the list. Dealing with issues like this during normal times isn’t so bad, besides the bill that is, but this isn’t normal times. Nope, we’re dealing with a pandemic, school is about to start, and to top it off, I firmly do not have the money to fix the damn car, what’s a guy to do?

Day 358: One small step

Dream big

Sometimes are points in life that you can clearly define as the before and the after. As a child sometimes those points are simple milestones growing up, starting a new school for example or moving to a new town. There is the before and the after. As you get older those points become few and far between. For example, you started a new job. Unless it’s your dream job, you don’t really think of it as one of these points and everything just blurs together. Thus the bar seems to get higher and higher as we age. Today I had one of those points.

Day 357: Thoughts from the lab

Case

My giant very suspicious case full of equipment from my school lab.

Well today is a busy day! I’ve got a lot going on so hopefully by the time you read this I’ll have all the setup taken care of. Working in two labs seems like a fun and interesting way to do experiments and it is! It’s also a huge pain.

Day 356: Solid Modeling – Week 9

Lamp render

This week we’re giving our lamp the finishing touches, including the plug! I decided mine needed a table top to sit on this week, but you don’t need to do that if you’re not feeling it.

It’s week nine! Welcome, to my little solid modeling course. As usual, we’re using FREE SOFTWAREĀ to do this, I feel that everyone should be able to learn if they want and this was the easiest way to do that. If you’re just finding my little series, you can find the full course in the Solid Modeling for Beginners category. For everyone else, we’re finishing our lamp today (for real this time!) and next week is the last week in the course! Let’s do this!

Day 355: Nostalgia for the unsentimental

Memories

One of the oldest photos I still have, it seemed appropriate for the post today.

To say I had a whirlwind of a life would be an understatement. Until my mid-twenties I moved at minimum once every two years. Not just moved across town, as in moved states. To be fair, as a kid it was bouncing between a few states. It wasn’t until adulthood that I started moving further away. Oddly enough, it wasn’t by choice, life just seemed to get in the way of staying in one place long enough to settle in.
