Day 341: Solid Modeling – Week 7

Lamp Render

If you’re following along you’ve made it to week seven! This course is taught using FREE SOFTWARE so if you ever wanted to learn how to solid model, this course is the one for you. If you’re just joining then you can find all of our classes listed here in our Solid Modeling for Beginners category. They are in reverse order, so start at the bottom. Today we are setting aside our lightbulb for a moment to create something to put it in. I’ve given up keeping what we’re doing a secret (since I always put the final product in the header image anyway). So with that let’s get to it!

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 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.

Light bulb render

Finishing our bulb today!! Wooo!!!

Welcome to week six! As always, this is a free class using FREE SOFTWARE. If you want to learn how to solid model, but couldn’t afford fancy or expensive software, then this course is for you. We’ll be taking things step by step so you (hopefully) will be able to follow along easily. If this is your first visit to my lovely series, then I would suggest you start at week one, which you can find in our incredibly helpful category Solid Modeling for Beginners. Today we’re going to finish our project from last week and make a super neat light bulb!

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 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 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 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 327: Solid Modeling – Week 5

Light bulb render

Okay everyone, I had a bright idea for our sphere… get it, get it!?!

Wow, week five already! As per my usual intro, this is a free class using FREE software so if you ever wanted to create a 3D model, this is for you and all you need is internet access to use the program we will be using. Now if you are just joining you’re going to want to start at week one, which you can find all the posts in the super lovely Solid Modeling for Beginners category. We finally did it, last week we made something cool looking! Today we’re going to expand on that and use what we learned to create another awesome thing!

Day 326: Review: The state of spinal cord research

Figure 2 from and yet it moves

Facilitation of stepping-like volitional oscillations using non-invasive transcutaneous electrical spinal cord stimulation in SCI subject. (A) Position of the participant in the gravity-neutral apparatus. (B) Biphasic electrical stimulation was delivered using unique waveforms consisting of 0.3–1.0 ms bursts filled by 10 kHz frequency that were administered at 5–40 Hz. (C) EMG activity of right soleus (RSol), right tibialis anterior (RTA), right medial gastrocnemius (RMG), right hamstrings (RHam), right vastus lateralis (RVL), right rectus femoris (RRF) and angular displacement in the knee and hip joints of both legs during leg oscillations with a voluntary effort alone (Vol), stimulation at T11 (Stim), and Vol + Stim are shown. (D) Schematics demonstrating the approximate location of transcutaneous electrodes above the lumbosacral enlargement, in relation to the location of the motor pools based on Kendall et al. (1993) and Sharrard (1964).

Well it’s been two weeks (roughly) and my PI asked specifically that this week I do a review on the state of spinal cord research, with emphasis on the spinal cord stimulation work I’m doing. So this review is going to look slightly different, namely it has a rather long references section (15 total). If you find this research fascinating I recommend “And yet it moves” (reference 5). It’s long, but open access and worth the read. I’m a little bias though, my Co-PI is one of the authors. In any case, I had two weeks to write this, so hopefully it is a good dip into what we know about the spinal cord and a lot of what we don’t. Enjoy!

Day 320: Solid Modeling – Week 4

Finished Rocket

We’re making something a little more exciting than a cube today. Yay!

Welcome to week four! For those of us just tuning in, this is a class for solid modeling using FREE software, so if you have internet access, you can do this too! You can find the whole course in the handy Solid Modeling for Beginners category. Last week we introduced a whole lot of navigation tools and helped you get situated into the world that you’ll be able to model in. So let’s get started by doing a quick recap of the past weeks and hopefully you’ve done your homework because we’re using that part today to make something more impressive than a cube.

Day 318: The why.

parts

With everything going on it’s been tough to write about just one topic. When I started 365 days, I started it with the intention of highlighting my struggles and trials through one full year of my PhD with the idea that I may (or may not) keep going for the duration of my PhD process. Then COVID hit, Black lives matter protests took off (finally), and I had the realization that I, like most people, am more than just my studies.

Day 317: Mental health and you

neural symphony

I scream it loudly from the mountain tops, I suffer all the fucking time from mental health issues. I do it because staying silent doesn’t keep me from feeling them and it does nothing for others who are suffering. Yes, it’s embarrassing to talk about it because it feels like a taboo, or something you’re making up, but that’s why we need to talk about it and why you need to keep track of your own mental health.

Day 316: Internships in the pandemic

Distance learning

For those of you not in academia, summertime means we get interns in the lab to learn about how research works in a real-life setting. We typically have them help with things that require basic skills, but lets them see how research really happens. This year, we are doing everything virtually thanks to COVID-19. This is a great thing because it really means we’re doing what we can to stop the spread while still giving students a chance to experience research.

Day 313: Solid Modeling – Week 3

 

Sketchup planes

This course will all be taught using free software so have no fear, you can do it too! For those just joining us you can find all the posts in this series in the handy Solid modeling for beginners category. For the past two weeks I’ve been going over best practices. The reason is the tools are straightforward to learn, but how we use them is what separates someone who is learning from someone who is a pro. I have had some thoughts about what I wanted to cover this week for that reason, but this week we’re making something and by me we, I mean you! First, let’s do a quick recap of what we’ve learned and we can get started.

Day 311: When voting isn’t enough

Gerrymander

Rawr! Beware, the Gerry-mander!

I’ve been debating about writing this post and it’s just been rattling around in my head for the past month or so. Voting can change the course of history, frankly we saw that in the 2016 elections, but we also saw something else. Your vote doesn’t matter and that isn’t by accident. But wait, I just said voting can change the course of history, so how does it not matter? Well for that we need to go back, way back.

Day 310: Review – Interfacing with alpha motor neurons in spinal cord injury patients

Figure 1 from the paper showing EMG recordings and the transformation using deconvolution to motor neuron spike trains

Spatiotemporal spinal maps of ipsilateral a-MNs. (A) Experimental set-up for ankle plantar flexion. (B) HD-EMG is decomposed into a-MN spike trains using a convolutive blind-source separation technique. (C) The spinal output to generate the neural drive to muscles is estimated from the a-MN spike trains.

The world is on fire, we’re protesting for a future, but today I have my review paper due so instead of writing about my frustrations I’m going to share my review. Today we’re looking at the effects of trans-spinal direct current stimulation (tsDCS) on alpha motor neurons and how we can determine that effect using electromyography. It’s actually a very cool paper, the work is well done, and it’s open source so you can read it if you’re interested.

Day 308: Don’t be ableist

trump water

Believe it or not, there are some people who can’t even lift a hand, much less hold a glass of water.

For those of you just tuning into my corner of the internet, I’m a disabled vet. If you looked at me most days you wouldn’t know it, but not all disabilities are visible and my TBI, back issues, shoulder issues, knee issues, chronic pain, chronic fatigue, memory problems, PTSD, aphasia … I could keep going, but you get the idea. My disabilities are (mostly) not visible. So today I have a very simple request, don’t be ableist.

Day 307: COVID19 and BLM or why you should wear a mask

statue

Despite the media blackout the Black lives matter protests are still going strong. To say I’m proud would be an understatement. Unfortunately with all the protests going on people are claiming that COVID19 isn’t as bad as people said it was, or that the protesters should stop because of the pandemic. The critiques all miss the point, this one simple trick will slow the transmission and it really works.

Day 306: Solid Modeling – Week 2

part 18

We’re back again with week 2 of solid modeling for beginners! For those of you just joining in, you can read the introduction (pre-week 1) in this post. You can also find all the posts in this series (including week 1) in the Solid modeling for beginners category. Solid modeling isn’t too difficult, but it does take time and it does mean you need to learn to think about objects in different ways. Week 1 did a great job of introducing this type of thought process and today we’re going to continue from where that left off. Let’s just dive right in!

Day 305: Trump, Godwin’s law, and history

Screenshot of Mike Godwin's tweet saying, "By all means, compare these shitheads to Nazis. Again and again. I'm with you."

Straight from the man himself, this is a very real tweet by Mike Godwin (Here).

Godwin’s law states simply “as an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1.” Coined by Mike Godwin, Godwin’s law is often invoked when talking about Trump or the horrid state the so-called US democracy is in. Here’s the catch, the law was suspended by Godwin himself when talking about Trump and company, for very good reasons.

Day 303: Police food fight

steakshack

Well here’s something I never thought I would have to write about, the food is all right. Contrary to reports by police, no one is poisoning their food. In fact, every time a new story comes up regarding tapered food and the police it turns out the officers involved were (surprise!) lying outright. There are strangely so many of these incidents that it’s hard to keep up with, what is it about police that makes them think it’s okay to keep lying?

Day 301: We mourn the loss of a beloved… wendy’s

Wendy’s burns

Rayshard Brooks was murdered by police. Murdered isn’t quite a strong enough word for what the police did, but we’ll go with it. He was murdered. I don’t know the man, but I can tell you he had three daughters and a step son. I can also tell you he was murdered for being responsible. He was murdered for celebrating his daughters 8th birthday. He was murdered for doing the right thing. But today we mourn the wendy’s that was burned down.

Day 299: Solid Modeling – Week 1

Full render

Welcome to solid modeling for beginners! Each week I’ll post some new and exciting things so you can try your hand at solid modeling. It’s easier than it looks to get started and once you do, you’ll be able to create amazing things that you can 3D print, plans to build something really cool, or maybe you just want to create some art! You can do anything you want with solid modeling, that’s the beauty of it! Let’s get started.

Day 297: Solid modeling classes, free for all!

Teaching online

Luckily teaching my course online makes it easier, not harder!

Today marks the start of my summer class. It’s a small group and while it doesn’t directly have anything to do with brain-machine interfaces (frankly none of my research in the lab does) in the age of commercialized 3D printing knowing how to solid model is an important skill that can be applied to basically anything, yes even brain-machine interfaces! Best of all, you can learn with us for free (software included)!

Day 296: Review – Spinal Rhythm Generation by Step-Induced Feedback and Transcutaneous Posterior Root Stimulation in Complete Spinal Cord–Injured Individuals

Black and white diagram showing the front and back of a human with the the placement of electrodes over the lower abdominal area and  separate electrodes over T11-T12 of the spinal cord a third image to the right shows the side of the spinal column with spinal cord to depict the location of the back electrodes with relation to the spinal cord

Transcutaneous posterior root stimulation: Paravertebral and abdominal skin electrode placement (this is just a portion of figure 1 of this paper.

Normally I’m somewhat excited to post these, but with everything going on you’ll have to pardon my lack of joy. However, it’s been two weeks so I need to review another paper so I’m sharing it here as well as sending my PI a copy. The study is a few years old, but it’s open access so you can read it if you’re interested. Transcutaneous spinal cord stimulation (TSS) is one part of my research in case you couldn’t tell from all the spinal cord and TSS studies and posts. I find it interesting and it gives me hope that we can help a whole lot of people living with spinal cord injury. Anyway give it a read and get out there and protest for a better world.

Day 293: TERF is NOT a slur

TERF

The I’d march with you… if I weren’t so busy discriminating against you defense.

Sex, gender, depending on who you ask it’s very simple or infinitely complex. I’ll give you a hint the science is settled and it isn’t as simple as people who shout, “but biology!” would want you to think. Sex and gender are most definitely a spectrum, it’s literally what the biology tells us and if you disagree, well then quit trying to use science as a defence for your shitty opinions.
