I wrote the code for my frc robot: github.com/FRC1360/Offseason2024 . It's UNFINISHED but the bare bones before testing are there (because my design team is taking forever and I still managed to make this on my own before them...)

Absolute madness. But the ECS is done! Hopefully it plays out great long term. The code is fine, a solid 7/10. Insanely easy to add entities with components through builder pattern. Can easily query with a lot of query params, also supports mutability. Wooo~!!! An example system to add velocity into position was also added. I like it so far. But it could definitely use some improvements. I learnt a lot about sparse sets, entity component systems, and especially rust's stupid borrow checker. Also wrote some unsafe code. github.com/sweattypalms/ferrumc/tree/ecs

Short Film Script I wrote a short film script about a killer with special abilities and a confrontation. I actually filmed a part with my friend but think that we're not going to continue working on it. :( Github Repository: github.com/nik-lmao/hackclub-arcade/tree/main/short-film

for both learning about how the minecraft bedrock api works, and wanting to better track playtime than available in the build in realms timeline, i wrote a plotly/dash python app that displays playtime data in a viewable format any realm one main pain point was trying to make the x-axis scale nicely to not have too much information when zoomed out, but still show the hourly data when zoomed in to a specific day github.com/caburum/minecraft-realms-playground

day I stopped counting of #arcade summer: I had lots of work this week outside of arcade projects so I only logged a couple hours but I'll just post the completion of yet another project, MacroPed! Why use two limbs while coding and have your other two jut sitting there wasting space? Make them useful by putting macros on the floor. This pico-based mechanical switch macropad lets you do that with a bunch of configurations for cad, vim, browsing the web etc. I wrote a couple keymaps but you can add your own too. (PRs more than welcome!) find out about it at github.com/Devnol/MacroPed

Finished a <https://angad.me/projects/hello-time/|blog post >that I wrote for one of my projects, Hello, time?. While writing the post I also spent a while debugging the project itself as timezones weren't being handled correctly. I didn't want to publish the post when the project had a major issue. Thus, I fixed the issue and then came back and finished the blog post.

I made a bunch of small changes to my portfolio website and wrote up an "About Me" page! I'm really excited, since it seems like the homepage is fully functioning and it is very responsive on mobile as well. Now I just have to finish my "Experience" page and add a contact form. Repo is located at github.com/commonkestrel/portfolio. #arcade

Day 21 of #arcade summer: Yesterday and today I didn't do much, I tried starting building something with #blot but I kinda left it in the middle: A little generator for putting different kinds of borders around a post-it note for decoration, like you can do in pages in Word. Did a solid and a dashed line but not much else. Then I remembered I had another old project in the backlog, A pico-based macropad for your FEET! (Trust me it makes sense). I had designed and ordered some boards last year using the OnBoard grant, wrote some basic code and did most of the 3d modelling but left it at that. In this coming week I've left I'll try to make some progress in that front and try to finish it all off. Today I designed some bridge things to align all the footswitches together in a sort of arc on the floor so you can easily access them like you would with keys around the home row of a keyboard.

Today, I completed the installation functionality for my desktop wrapper of "croc", a file-transfer utility. I wrote it in GoLang, like the original package but with the added Wails library to access HTML/CSS/JS bindings for the design. Currently, it only has the ability to install croc, but eventually I will integrate the rest of the functionality that croc provides into the app. You can look at the source code here: www.github.com/CrazeXD/croc-desktop

I wrote a brainfuck interpreter in Go: codeberg.org/gregorni/gofuck This interpreter is incredibly simple and simply evaluates one character after another. This means it takes a long time to execute more complex brainfuck programs. I went on to write an optimizing interpreter that evaluates all code before running it. This means it is substantially faster. codeberg.org/gregorni/gofuck-optimized In the demo video I compare the normal interpreter against the optimized one.

slackbot ship! I was about to start on a new project this morning (yes i made this whole project in one morning) when I realized; I am so going to just reimplement the same framework for building and running my slackbot :skull-ios: so i made a reusable template that allows me to just forget about that setup and get to the fun part of making a slackbot more quickly! I wrote pretty extensive docs which is very unlike me so enjoy! github.com/kcoderhtml/slackbot-ultimate-template

I wrote an API for a website to host Minecraft servers. This is an 'alpha' release, at a functional milestone (to ensure I don't go over the limit of banked hours for #arcade). There are currently no provided binaries in the GitHub repository. You will have to follow the guide on how to use it. You may notice the small front-end in the src/main/resources directory, but it is more like a placeholder and the actual front-end is still under development by @Tristan-U078RF4CWHG. Pretend it doesn't exist. Here's a demo on the usage of the API:

I tested electronics (electromagnets and stepper motors) for my "replac3d", a 3D printer build plate replacing robot. I wrote some code for controlling a TMC2209 stepper driver with just the step and direction pins, and also soldered some wires (in my scraps). More info is in the project's README. If you are interested in this project at all, feel free to DM me! The repository contains the README, .STEP and .F3Z (Fusion360 Archive) files, and for the electronics and code in this ship, videos with the electronics in sight, as well as the .INO file for the motor control.

Slack Member Scraper This project was first for an leaderboard for the arcade. But because the api now needs authorization 😞 here are the slack scrapers i wrote 🙂 github.com/iambodha/Slack-Member-Scraper Hope this is useful to someone else 🙂

3.1 / 3 Blot Artwork: Seaside Serenity My artwork is an ocean scene consisting of many trigonometric and randomized patterns. The main features of the scene are the waves, the sun, and the clouds, each of which have variables which can be modified or randomized. For the waves, the frequency, phase shift, number of waves, and interval between the y-coordinates of each wave can be found in variables at the top and randomized with a randInRange(min, max) helper function which I wrote. For the sun, you can randomize the radius, and for the clouds you can randomize the size of each circle creating a cloud. The waves are sine waves drawn with startY + 3 * Math.sin(frequency * (x - startX) + phaseShift). I had a lot of fun working on this project and I can't wait to build a Blot machine and have my work drawn :) github.com/hackclub/blot/pull/584

Day 129 || 15 of #15-days-in-public! Today I worked for what felt like five hours on getting my microcontroller to decide to send IR signals. Finally after lots of googling & almost giving up, I figured out how to send signals! After I got that working I wrote some calibration functions and determined the number different colors of my lights could display (19863 or 27^3). Then I implemented some interpolation functions so I can smoothly transition between any two colors with as many steps as I would like. Here is the code if you would like to try it on your LED light strips: github.com/evan-gan/RGB-light-strip-controller If you want to learn more I recorded a video with details (it's to large for scrappy but you should be able to view the link)

I got a party tracking module working in MCProxy. It uses the hypixel mod api along with a wrapper I wrote for it in typescript (the first publicly available one at github.com/TBHGodPro/Hypixel-Mod-API-JS) along with the lunar client apollo server-to-client api with also a wrapper I wrote for it in typescript (also the first publicly available one at github.com/TBHGodPro/LC-Apollo-JS) and merged them with MCProxy so you can keep track of your party members with a simple indicator, even through walls! github.com/TBHGodPro/McProxy/commit/074e55cc39f1c42c8d9839a96bfee50aae9f756a github.com/TBHGodPro/Hypixel-Mod-API-JS/commit/19657ef612e55f692017aae2517f5e88e4c5d52e github.com/TBHGodPro/LC-Apollo-JS/commit/25647aa2325bc573127afc7d23d87b5c717e541a
