We're a little crazy, about science!

The grant proposal

Well today one of my grant proposals is due. Technically it’s due tomorrow, but I always try to submit a day early. Why? Well, technical issues, I’m an anxious person, all that good stuff. This was an equipment grant and I did it at the request of my PI, it’s not the grant I want, but it’s a learning experience, or at least that’s how I’m treating it.

Exoskeleton experiments

Just a few of the exoskeletons we have in the main lab, two of them are self balancing the other two in the shot are not, but they all have different purposes.

Well let’s toss something else into the pile of “things I’m going to talk about, but can’t share the details because we’re working on a publication.” I’ve got yet another new project I’m working on! This is going to be so freaking cool and I’m super excited to start it. So let’s go over some of the details, at least the bits I can talk about. Eventually when all this stuff gets published, I’m going to have a ton to write about.

Experimental failure

Well that was a …flop. Today I had an experiment, had. There are a lot of moving parts when it comes to an experiment, especially in my line of research. Technology, can’t live with it, can’t live without it. Still, somedays I wish I was living in the future, one where I didn’t need to reset my router randomly. Then I would know for sure the singularity was close.

A wild collaborator appears!

A robot… in parts.

It seems like weird stuff just keeps happening left and right lately! Yesterday out of the blue I heard from a collaborator I worked with from the UK. It’s been months since we last spoke and he had some personal issues due to COVID, so I wasn’t actually sure I would hear from him again.

The Nyquist frequency

Parts to a wave (top left) a example wave (bottom left) and different examples of how waves change based on frequency (top right) and amplitude (bottom right)

A few days ago I realized I had never bothered to explain the nyquist frequency. Considering it’s been over a year now since I explained some of the frequency domain things that I do in my lab, I’m actually surprised I missed something so important. Well, better late than never today we’re going to explain the nyquist frequency and why it matters… to my work at least.

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.

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.

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?

Day 339: What will school look like?

School

Here in the US we paused, it was only for a moment, it wasn’t long enough, and not everyone did it, but we paused. Then just as quickly as we tried to adapt to the changing times we went back to pretending everything was normal. Beaches opened, restaurants opened, bars opened, we saw celebrations and parties and we ignored a single digit daily death count, which turned into a double digit, then triple digit, now we’re hovering in at roughly 1000 deaths a day from the pandemic.

Day 338: Feeling stuck, again

feeling stuck

I’ve probably mentioned this before, but I feel stuck. With the pandemic going on and the protests (Which are still happening!) I don’t feel like there has been any forward movement in anything I’ve been involved with. I hate feeling like this, it’s so frustrating especially when I feel like I’m drowning in work to be done.

Day 337: The end of summer mentoring

virtualconference

Still trying to get used to the idea of virtual conferences.

Well we still have a month of summer break left, but we do have the end of summer courses coming. In just a week we’re having our undergrad researcher conference (virtually of course). Everyone will get a 5 minute block to showcase their poster, talk about their experience, and get a chance to answer questions about the projects they worked on (another 5 minutes max). The whole thing will take three days to get though.

Wear the mask!!

I was up bright and early today, 4:30am to be exact. We had two experiments planned for the day, one first thing in the morning, the other in the afternoon. Being the dependable person I am, I was up and out on time, arrived here early and setup to get started. That’s when it all fell apart.

Day 334: 3D printing, my final summer class

Robot parts

One of the slides I used in my 3D printing course, this was the robot I designed and 3D printed (prior to assembly) for my Masters degree.

Well I got a chance to give my last lecture yesterday (virtually of course) on 3D printing. I worked literally weeks to get everything ready and it went off (mostly) without a hitch. The world of 3D printing is full of vast, multifaceted, and divergent technologies with more applications than I could possibly list in a single lecture. In fact, they offer entire 12 week courses on 3D printing, so I had to cram everything together into a nice 1-2 hour presentation, where to start?!

Day 333: Solid modeling course day 3

3D printer

My 3D printer still working hard, but I’m still having troubles!

Yesterday was the last day for my solid modeling class and surprisingly I got more questions than the previous days so that made me very happy. Today is my 3D printing course, so we’ll talk about how that went tomorrow (and push back our online 3D printing course by a day sadly).

Day 332: Solid modeling course day 2

Printer

Yep, still dealing with printing issues so I have the dual extruder on. Ugh!!!!!! 5 HOURS still left on this print. Why does 3D printing have to be so sloooooooow?!

Well yesterday was day 2 of my solid modeling course, today is my last day of the class. Unfortunately tomorrow is my 3D printing course and I still haven’t got my printer well behaved yet. I guess we get to see all the 3D printing troubles! In any case, let’s talk about how the class went yesterday and what I have planned for today.

Day 331: Solid modeling course day 1

20200715_134927

The dual extruder attachment, the current bane of my existence!

Well can’t complain too much about the first course. I’m used to people talking to me so it was an odd feeling talking into a screen with no one talking back. I had a few questions, but mostly the course was on how to think about solid modeling, so maybe not a lot of room for questions?

Day 330: I’m teaching this week!

Harbinger

I love mass effect, so I really thought this was a perfect header image for the post since I am… assuming control!

Well I mentioned it a few days ago, but it’s day one of four today. I’m teaching three courses on solid modeling and one on 3D printing * Shakes fist at 3D printer who keeps giving me problems * and I figure I can talk about how my classes go after the fact, but let’s talk about my prep for these classes so my students get the most out of what I have to teach them.

Day 329: More 3D printing issues!

Cat boss

My boss is not happy with the work I’m doing, you can tell since she didn’t want to look at me when I took this photo.

I’m giving a class on 3D printing this week and of course my printer decides it wants to throw a fit. So my print had to be stopped (18 hours in) and the printer needed a good talking to. It’s not the printers fault, maintenance happens, so let’s talk more about my poor FDM printer (Acronym defined yesterday).

Day 328: 3D printing… ugh

3D printing

Well it’s time, in a few short days I’ll be doing a marathon session of courses for the summer interns. I admit it I bit off a lot! I’m doing three solid modeling courses, so the basics, plus a 3D printing class. Today we’re talking 3D printing because, well it’s a headache even though the prints themselves can be worth the pain. I know if I can pull off printing what I’m working on now it will be worth it… I hope.

Day 324: Rewriting

edits

Today is a bunch of meetings and a bunch of editing. As I mentioned (or at least think I mentioned here), I had to meet with the senior author for the paper I’m working on and I got a lot of feedback, some of it was good, most of it meant more work for me. That’s the process though, write, rewrite, re-re-re-re…rewrite.
