Weekly Overview
#

The early to middle part of the week was productive, but I struggled with consistency toward the end. Still, it’s a solid starting point, and I aim to be more consistent next week.

Summary
#

  • Study:

    • - Embedded Systems
    • - Artificial Intelligence(AI)
    • - Semiconductors

  • Side Projects:

    • - AI TTS App: Start work - R&D, Planning
    • - Nalnda: UPI integration in the android app.
Reflections and Remarks
  • Embedded Systems:
    • Continued reading the book: Making Embedded Systems by Elecia White, Chapter 2.
    • Learned a lot about how to design software, hardware, or a complete system in general.
    • Learned a lot about how to think of design at a very beginning stage of a system. How to create different type of system diagrams to represent the system and refine them over time.
    • How to think about coupling and cohesion in a system, what modules to merge, what modules to keep separate, etc.
    • Never thought of these things before. This is a very good book. I especially like the way the author explains things.
  • Semiconductors:
    • Learned a lot about semiconductor basics, remembered some things I studied in the 11th grade.
    • Read some blogs on how to get started in this domain. I especially liked this one.
    • Watched some videos on YouTube and the whole thing feels like magic. Very exciting.
    • Bought the domain: semiconductors.blog, might start a blog as I learn along. Not sure yet.
  • Created Idea Submission form. Use this form to submit your project Ideas. Will later check and evaluate which Idea is worth implementing and work on that. Great way to keep all Ideas in the same place. All Ideas from the filling of the google form are then added to a google sheet.
  • AI TTS App:
    • Was reading some articles today morning on various domains I am interested in. Wanted to hear them in audio format. Thought of using TTS to convert the articles to audio, but the basic TTS engines sound very robotic. So thought of building an app that can convert text to speech using AI voices which I can run locally on my machine and won’t cost too much money like ElevenLabs subscription.
    • I am sure there are some tools that do this, but I want a tool where I can just paste the link to the article and it will fetch the article, and read it using human like AI voices, without costing too much money. Because I think(and I might be wrong) that simple AI voices could be done using smaller models which will still sound good and cost less or no money at all. Maybe like the open source models. Anyways, it will teach me a lot of things and get me started with AI based projects.
    • Started to learn about basics of LLMs, what are tokens, etc. Very basic stuff. Will learn more as I go along.

  • Study:

    • - Embedded Systems
    • - Artificial Intelligence(AI)
    • - Semiconductors

  • Side Projects:

    • - AI TTS App: Scraping, Cleanup
    • - Nalnda: UPI integration in the android app.
Reflections and Remarks
  • Overall, not very productive day but still got some work done.
  • AI TTS App:
    • Started building the app in rust for some reason: I guess I felt like writing some rust today after more than 2 months.
    • Here is the flow: User provides link to the article -> It reads it in a human like voice.
    • Built a simple cli and scraping tool in rust to get useful article content out and did some research on various TTS models, will integrate it tomorrow.
  • Nalnda: UPI Integration
    • Did some codebase study of the existing react native app and built like a small test screen in it for the UPI integration. Need a UPI merchant ID: waiting for it. Will do more after I get the merchant ID.

  • Side Projects:

    • - AI TTS App: Continue work
    • - Nalnda: UPI integration in the android app.
Reflections and Remarks
  • Pretty exciting day.
  • Explored a lot of projects, AI tools, models, etc. I was missing so much. Will explore more AI.
  • Embedded Systems: Not much to report. Continued to learn about system design, like it so far.
  • Did not get time for semiconductors today, actually I just procrastinated. Will do better tomorrow.
  • AI TTS App: Did some more cleanup, etc of the raw content.
  • Nalnda: Will take 2 days to get the UPI merchant id, so waiting for that.

  • Study:

    • - Embedded Systems
    • - Artificial Intelligence(AI)
    • - Semiconductors

  • Side Projects:

    • - Vibe coded Calculator android app for Indus AppStore
Reflections and Remarks
  • Mixed day overall. Some good, some bad. Trying to reduce the procrastination.
  • Vibe coded a react native calculator app, landing page and privacy policy for the same to release on Indus AppStore. Its in review. Hoping it gets accepted soon 🤞. Checkout the website here.
  • Explored so many AI products today. Man this domain is huge. Would love to build some products in this domain. Will take time to learn the basics first.
  • Embedded Systems: Finished chapter 2 now. Boring part is over I guess. Looking forward to Chapter 3, where I get to learn some hardware stuff. Really excited.

Reflections and Remarks
#

  • I haven’t been very productive the last three days, but I’m not giving up. As they say, it’s a marathon, not a sprint.
  • Did some small changes in the Nalnda website.
  • Made a landing page for semiconductors.blog. Just a simple landing page which features an email to get in touch. Still don’t know what I am gonna do with this website. If I have to guess as I learn more about semiconductors I will do some good writeups on the website. But still can’t say for sure. Maybe I end up selling it to someone. Let’s see.
  • Something amazing happened over the last 2 days:

    • I started watching some George Hotz interviews, him jailbreaking the iphone, and what he is doing in self driving cars with comma.ai.

    • I came across his blog post on AI Coding, which gave me a lot of hope. There was one line in the article that really stood out to me:

      Some people go as far as to believe that perception is reality and that truth is a construction. I hope there’s a special place in hell for those people.

      Something about this line resonated with me and made me feel good about programming again. Lately I was feeling very demotivated, because of all the AI doomsday talk.

    • This has also made me very interested in AI, I will learn more about it and try to build some stuff.
