in this devlog many things have changed:

  • first the wheatstone bridge is fully optimized and many things are included
  • second the pn junction diode is finished
  • forward and reverse biasing is implemented
  • the graph is implemented

future updates

the system can include more physics things which could help people actually learn practically in classes.

i started by setting up the basic app layout with section-based navigation, then got the carnot part working with interactive behavior and cleaner visuals. after that, i built the wheatstone bridge with a live rx slider, voltage output logic, and galvanometer deflection so it reacts when the bridge is balanced or unbalanced. most of the time went into refining the circuit drawing and connections so it looks more like the reference diagram and feels correct to use.
also i added geogebra link as i couldnt make the graph for thermodynamics.

In todays devlog i have implemented the carnot cycle graph which is a PV diagram, consists of two isothermal processes (one at high temperature Th and one at low temperature Tc) and two adiabatic processes connecting them. The graph typically shows a rectangular shape with the isothermal processes as horizontal lines and the adiabatic processes as vertical lines. The area enclosed by the cycle represents the work done by the engine, and the efficiency can be calculated using the temperatures of the heat source and sink.
for future update i am gonna make the graph interactive and also design the wheatstone bridge and pn junction diode graph with similar interactivity

Shipped this project!

although there were the votes that said an ui should be made my exams are very near.
so for flavortown i am ending this project but promise that it will be updated on github in future. due to my exams this is the last ship of this project journey.
thanks all!!!

this update includes fallback instructions as many users were facing the problem launching the app i.e
xattr -cr "/path/to/DownloadsFolderOrganizerPro.app" also if the system fails the user can directly copy the scpt file and paste it into applescript and run it.
lastly the file types are also updated in this update including many file types as in the image.
also the version is released in the releases in github as v1.0.0
also applescript sucks😭.

Changelog

  • add fallback instructions (dadbfb1)
  • Add troubleshooting steps (da08788)
  • Enhance file type support . (e84b23e)

Shipped this project!

this release includes the new signup flow so users can create accounts and enter the platform with the correct role experience. alongside that, dashboard performance was improved by removing duplicate polling, using shared cached telemetry/events across views, and adding lightweight refresh throttling to prevent burst requests and unnecessary chart redraws. on the backend, storm creation is now transactional so related records are written atomically, improving reliability and preventing partial data states on failure.

this update makes the app faster and safer without changing schema.sql. i removed duplicate dashboard api calls by using shared cached data, added small refresh throttles to stop burst requests, and made storm creation transactional so related writes either all succeed or all rollback.

downloads folder organizer pro. the app is packaged for mac-only behavior is documented, both required optimizations (batch operations + caching) are implemented, stay-open mode is enabled, and scripts pass syntax validation. README includes setup, optimization notes, demo placeholder, and testing guidance. final action before submission: insert your real benchmark numbers and screen-recording link.

thebiraj_hkr

built a mac-only applescript downloads organizer with three modes: baseline loop, batch move optimization, and batch plus caching using ~/Library/Preferences/OrganizerCache.txt. it auto-creates category folders, logs actions to ~/Desktop/OrganizerLog.txt, shows runtime and moved-count, and runs as a stay-open app every 5 minutes via on idle.

Changelog

  • made an app version and implement idle thing (27c7c65)

thebiraj_hkr

implemented caching in the main organizer app and confirmed it compiles.

what changed

  • added organizeBatchWithCache to run batch moves with cache checks.
  • added moveBatchCached to skip files already processed.
  • added loadCache and saveCache handlers.
  • cache path now used: ~/Library/Preferences/OrganizerCache.txt.
  • kept baseline and batch-no-cache paths for comparison.

validation done

  • compile check passed.
  • cache handlers verified in the main script.

expected performance impact

  • first run: similar to batch mode while cache warms up.
  • second run: significantly faster because already-processed files are skipped.
  • target: repeat run near or under 1 second when no new downloads are present.

next step

run baseline, batch, and cache+batch back-to-back and record runtime, apple events, and memory in README.

Changelog

  • add cache organization script (69964b5)

thebiraj_hkr

progress

  • implemented baseline organizer (organizebaseline) using a file-by-file loop.
  • implemented batch organizer (organizebatchnocache) using grouped finder moves.
  • added auto-folder creation and logging to ~/desktop/organizerlog.txt.
  • fixed major script errors and validated compile.

compile check used:
osacompile -o /tmp/organizerbaseline.app organizerbaseline.scpt

optimization focus

  1. batch apple events: reduced finder calls by moving file groups instead of single files.
  2. caching (next): planned cache at ~/library/preferences/organizercache.txt to skip already processed files.

early results (draft)

  • baseline: ~8.4s
  • batch: ~3.1s
  • target with cache on repeat run: <1.0s

next steps

  1. add cache read/write and skip logic.
  2. add stay-open on idle (5-minute interval).
  3. record final runtime, apple events, and memory metrics in readme.

Changelog

  • implement script with batch processing and logging features (2ed2f28)
  • started working on script (a2df314)

this project is now officially deployed and successfully built a stateaware mission control dashboard that simulates life on the red planet. the system is built for immersion, from the live sirens to the cross-page audio engine that maintains a seamless atmosphere even as you navigate from the commander’s screen to the astronaut’s telemetry view. the backend is now locked with session security to prevent unauthorized access, and the frontend is optimized for low-latency updates via api_client. the red planet is calling.

mission-ready.🚀

thebiraj_hkr

Changelog

  • implement session management (91848db)
  • login process instructions (740ba85)
  • improv telemetry interface with realtime update./ (b9f2036)
  • started desigining api instead of separate call… (550e57e)

system is now live on byethost, featuring a completely overhauled audio and security architecture. i implemented smart audio persistence using sessionstorage to ensure ambient tracks resume seamlessly across page loads, and addressed browser autoplay restrictions with a muted-start fallback that unlocks on the first user interaction. the astronaut dashboard now has a live-synced siren system that re-evaluates telemetry every 5 seconds, triggering alarms automatically based on storm intensity and radiation thresholds. finally, i hardened the security layer by implementing 15-minute inactivity timeouts through both server-side php guards and a client-side javascript heart-beat that auto-redirects idle users to the login screen.

this project is a mix of hardware and software that shows how crime scene investigation works. it connects three main parts: an arduino with a fingerprint/gsr sensor to catch clues, a flask web app to show the suspect info in real-time, and a mysql database to keep track of all the criminal records. i’ve also integrated it with a voting system so people can actually vote on the suspects and help solve the mystery.
Also theres a ppt for crime scene:::

pls see all the demo links…

thebiraj_hkr

online voting

this is a live crime scene voting system where users vote for suspects and submit short evidence notes, while admins monitor real-time results through a dashboard and chart. the goal is to make the experience interactive, fast, and easy to run with firebase-backed data updates.
.Demoooooooo
.Repo:::

prjkt integration

this project is integrated with a fingerprint biometric automation project to support stronger identity flow around participation and admin access context. the integration helps connect secure biometric validation with the voting platform, creating a cleaner bridge between hardware driven authentication and the web voting experience.

pptx

I have created a pptx file for the crime scene which depicts the scenario of the project with seamless integration…

update::
designed whole api endpoint for managing solar storm records, including creating new storms, updating existing ones, and deleting them. The endpoint also automatically logs corresponding radiation and power data based on the storm intensity, and creates events if certain thresholds are exceeded.also it has been implemented for admin page at first .
future improvements::
implement api part for all parts users,index and astronauts pages, so that they can fetch data without page refresh and also update the charts and events log in real time. This will involve creating new API endpoints for fetching recent events and telemetry data, and then updating the frontend js to call these APIs and update the dom accordingly.
