Definitely one of my better Jubilee GIFs.

Work update: We built a really cool microscope and took some beautiful 🧠 pics along the way.

Working with this crew has been an absolute delight. The banter, puzzles, and joyful whoops we've shared together have given the journey a "Mars mission"-level feeling of excitement.

How do you image the large and the small at the same time? We developed new 🔬 technology to image centimeter-scale specimens - including whole mouse brains 🧠 - with diffraction-limited resolution and without sectioning. #mesoscale #imaging

oof, circumstances were such that I almost fell for this! But my real PI would've totally gotten the Peano-Baker Series.

Honestly kinda bummed I didnt get a reply, even something random from Wikipedia.

new video, this time playing around with air assist and nozzle designs on a diode laser cutter: https://t.co/vyV49DJtjZ

And with that, we've made a rugged "five bar linkage" leg by mixing imprecise hand tool processes with precise CNC'ed parts!

[Sonya Vasquez @Poofjunior]

Since it's engineering week, how about some prototyping design patterns? Let's talk about fabricating the "center post" and "foot" of this five bar linkage robot leg. Here, the center post constrains the angle of the foot as the leg travels around its workspace.

[Sonya Vasquez @Poofjunior]

The foot attaches to the carbon fiber "leg" with a shoulder screw and a sandwich of thrust bearings. Shoulder screws are great for pivot points. The bushings and thrust bearings (blue, bookended by 2 washers) together form a low friction, high-force joint for the pivoting foot.

Nowadays, I'm working on having a healthier relationship to my work, my projects, and the blurry line that separates them. But for now, it's time to make space for cozy Sunday mornings with tea to get my brainwaves back again.

As my ol' college prof used to say, happy hacking!

[Sonya Vasquez @Poofjunior]

I'm simply stoked to say that Jubilee, my open-source tool-changing machine and first grad school labor of love, is now a kit via Filastruder!

[Sonya Vasquez @Poofjunior]

Jubilee was built @Machine_Agency and refined over ~3 years. Kit-izing Jubilee has been a collab between the folks at @Filastruder, @LukesLaboratory ,@MandalaRose4, and @LDOMOTORSJASON, not to mention the plethora of feedback from people chronicling their experiences on Discord.

@Stefania_druga @XandaSchofield I appreciate the bump Stef! I have a looong way to go before i am visiting professor material, but i am shooting for it in my lifetime.

[Sonya Vasquez @Poofjunior]

@frikkfossdal The project is running SPI data over a long wire, noise-free (*hopefully)! This is the sn65lvdt41 on a breakout board, which turns single-ended logic levels into differential signals. The complementary chip, the sn65lvdt14 converts it back on the other side.

The heat shrink tubing labeler makes for some great circuit, uh.. grooming, for special occasions.

[Sonya Vasquez @Poofjunior]

@RudyHouque Not a Brother, but otherwise, yes! I made these on a Rhino Dymo 4200 with some heat shrink tubing cartridges. It kinda blew my mind that you could do this, but it's super handy for sanity checks and example layouts.
