The first day of the project started with a focus on getting TF-IDF set up and connecting the data to the format that scikit-learn expects. Also, a brief diversion to start with small data before going to the big data approach.
Project Concept: Supercharging Evernote Building
I'll admit it. I'm a document hoarder. For years I've been collecting and tagging notes in Evernote as I'll read through them to save for later. Can I use that hoarding to learn better?
FormaK Week in Review 2023-01-13 Building
It's been a little while since I last wrote about Formak ( FormaK Under The Hood: Optimization for scikit-learn integration , Sat 08 October 2022). Since then, I've been busy adding functionality to FormaK and I've also been improving the tooling for the project, inspired by Boring Python: code quality. The latest piece of functionality is the C++ code generation. The PR is in progress, but the initial experiments have proved out that the generation pipeline is feasible and able to be integrated into bazel.
CPU Modeling: First Order Latency and Data Dependencies Building
This post is a new episode in a miniseries focused on modeling the workings of a CPU to use for generating optimal code. This post focuses on taking a sequence of instructions and simulating their results while respecting the latency of each instruction execution and data dependencies between instructions.

I Love Bazel, I Hate Bazel Building
I love Bazel. It's one of those satisfying tools where computer science algorithms and data structures fuse with good software practice to create something that's satisfying on many levels. It knows how to minimally rebuild things. It knows how to hermetically build things in a repeatable way. I also hate Bazel.

Restomod Day 28 Building
Two more iterations on the battery cover / side skirts
Restomod Day 27 Building
Iterating on designs for a more "aero" replacement battery cover and the rear bumper
Restomod Day 26 Building
Today was focused on quickly iterating to getting a functional rear bumper designed for extra airflow.
Restomod Day 25 Building
Today was mostly focused on how the rear bumper fits on the body
Restomod Day 24 Building
The first order of business for the day was printing the new aero front bumper. The end result was somewhat flimsy and didn't print well, but it's a great start. It's probably the least manufacturable of the part designs by traditional methods so far, making it perfect for 3D printing once the print is dialed in.
Restomod Day 23 Building
The first round of chassis dyno printing is done. During initial testing I noticed that the car did not track straight, so I added guides to some of the rollers so that the car would be encouraged to remain centered on the dyno and not roll off into the sunset when I wasn't looking. It also makes higher speed testing more boring (in a good way) where the car has less of a chance (but still a chance) to jump off the rails and drag around higher voltage cables.
Restomod Day 22 Building
The parts for the full chassis dyno arrived. After an initial print on the rollers and the bearing housing, it looks like the design is mostly ready.
Restomod Day 21 Breaking
Today was mostly a breaking day. The printed half-shaft design melted itself apart after some high voltage testing for a couple of minutes, so it's going to need a redesign.
Restomod Day 20 Building
Electronics time! Today I got the bench power supply hooked up to the fully running chassis that lives under the '05 Mustang.
Restomod Day 19 Building
The suspension work continues! The rear design is now printed in a high-shell configuration. This leads to (mostly) nicely aligned filament.
Restomod Day 18 Building
The suspension work continues! The rear design with very short arms plastically deformed after the first flex, so I ended up changing to a more complicated design with longer arms. The new design should also allow for equal length and thickness arms on the front and rear designs.
Restomod Day 17 Building
Today focused on simplifying the suspension with a printed design. There's nothing fundamentally wrong with the existing XMods suspension, but I do think there's room for improvement. For example, the existing suspension limits its own range of motion and has relatively poor ground clearance. Also, I've taken it upon myself to replace most of the front clip with printed parts now that I've gone off the deep end and printed the uprights.
Restomod Day 16 Building

Pictures from Day 11: Replacing the axles to enable using metal sleeve bearings
Restomod Day 10 Building
The triumph of the day was proving out the concept for creating custom wheels. The center hub uses a D-shaped drive and is sized so the wheels snap-fit into place.
Restomod Day 9 Building
Today's focus was on replacing the wheels for the XMods. This has two purposes: I've wanted to play around with printing my own wheel designs and I wanted to experiment with replacing the wheel axles to see if I could reduce slop in the wheels that comes from a loose fit between the axles and the hub.
Macro Lens Shots Building

Restomod Restoration Aspirations Building
One of the more complicated restorations that I'll need to complete is reviving the older shorter chassis for the Mitsubishi Lancer Evo and the classic Ford Mustang.
Restomod Day 8 Breaking
One aspect of reviving the XMods parts that I have involves figuring out what I need to fix to get the shorter chassis running again.
Restomod Day 7 Breaking
The wheel mounting design leads to some slop in the location of the wheels. In taking apart the mechanism, it appears that the slop comes from the plastic bushings not locating the driveshaft precisely.
Restomod Day 6 Building
The latest design has almost all of the features that I'm looking for, with support for some more interesting customization to go beyond the style of the original bumper.
Restomod Day 5 Building
Before and after pictures, the design is almost a good fit. There are some spacing issues at the wheel well but visually the layout and the headlights are close to the original style.
Restomod Day 4 Building
The first attempt at curvature got close, but the dimensions didn't line up with the hood as expected.
Restomod Day 3 Building
With the first prototype, I focused on getting something that would fit the 3 mounting points on the standard body.
Restomod Day 2 Building
With the first prototype, I focused on getting something that would fit the 3 mounting points on the standard body.
Restomod Day 1 Building
I recently dug up a box of parts for XMods, 1:28 scale RC cars with customizable chassis and bodies. Along the way I've started to document what I'm working on. The first project is going to be replacing the front bumper of the 2005 Ford Mustang.

I decided to go for the full-break method of investigating the electronics, and while it worked out well to start, it's looking iffy going forward.
Tearing Down a Quadcopter: Part 3 - Reading a Circuit Board Breaking
My background in electrical engineering involves the first 4 chapters of an electronics textbook I read on my phone when I had internet connection and power in town while hiking the Appalachian Trail. What can I figure out about how the circuit board works for the quadcopter?

Mechanically, it's in shambles. What's left in the rubble? I dive into the electronics to figure it out.
AT Hiker Plays Firewatch: Day 1 Building
I've had the game Firewatch for a while, but I just started playing the game today. What makes the game particularly special to me now is that I spent last summer hiking the Appalachian Trail. Many aspects of the game bring back memories from that experience which I think is kind of amazing. This probably will spoil some of the game for you if you haven't already played. Day 1!
Tearing Down a Quadcopter: Part 1 Breaking
This has been a back burner project for a while; I'm now finally taking the time to take apart a quadcopter I've had for a while to see what goes into making it tick (and see if I can't mess with it a little bit too)
