🛠 I make open-source hardware for home automation at & share them on YouTube My Tweets are mini progress journals 🔌 📝

I still cannot believe that I can:

- look at a world map and tap anywhere to zoom in at street level

- instantly access any song, book, movie, tv show, or podcast ever made

- have any conceivable question and get an immediate answer or video explanation

- take a photo or video wherever I am and add it to my massive, searchable, always accessible personal archive

- video call anyone in my life, at anytime, no matter where they are

- watch live sports on a little wireless glass rectangle

- type out these thoughts and have them read by thousands of people, all over the world, a few seconds later

I always use CoPilot to generate Git commit messages for code.

But, today I was pleasantly surprised that it can create a commit message on KiCad schematic and layout changes too! Because these files are also based on text 🤩

[Sayanee @sayanee_]

Love mine too 🥰

This is fun! I wasn’t sure what was going to come out of the chatgpt memory feature, but if you left it accumulating memories for many months it seems to be able to get a pretty good sense of you from all your queries and over time. I saw other versions of it too, e.g. “tell me something I may not know about myself” etc. Mix of fun/interesting, maybe slightly unnerving.

(At each query the model has the opportunity to write down notes about you in text, and these memories you can view delete or just disable)

@erikengheim With LLMs, it's even easier for parents now. I have been appending all the kids' questions to ChatGPT/Claude AI as "Explain it to my 4-year-old ..." and then "Give me the adult explanation now"

[Sayanee @sayanee_]

@stefanjudis Yeah, I always do it. Write a failing test in TDD or leave a small task unfinished at the end of the day to restart tomorrow without having a blank mind.

The psychological effect is called Zeigarnik:

@cloud_balma Currently, I am using ChatGPT to generate code and home automation ideas or even summarise technology history 🙂

[Sayanee @sayanee_]

#ChatGPT has become my therapist, holiday planner, video analyzer, historian, and initial template generator for code.

I can't quite get that same effect with DALL-E 2 yet, but it's all about learning effective prompting right?

Which type of Generative AI do you think will have a bigger commercial impact: Generating images (e.g., diffusion algorithms, stable diffusion) or text (e.g., LLMs, ChatGPT)?

☠️ #TearDown of the "Freestyle" projector by Samsung!

It won a best invention prize, so it must be good:

It embeds a full computer and #sensors for auto keystone and it was unclear if they could be #repurposed, so opening it seemed necessary 🔥

@tferriss @NoahRFeldman Would love more episodes on a deep dive into current events!

I too have been stepping back from consuming the news all the time to maintain a healthy mind and cut down screentime.

Thanks for what you do 🙏🏻

I took my first step into the world of 3D printing with an electronic enclosure with KiCAD and FreeCAD 🙋🏻‍♀️

I share all the steps in this video:
https://t.co/k2adAVrDAR

🔢 parametric design
🎛3D model of the PCB
🔌 connector slots
🎐ventilation holes
🔩 screw lugs

[Sayanee @sayanee_]

FreeCAD + KiCAD integration has been rad ⚡️

I should have done it from the start to get the correct fitting when making an electronics enclosure. Next on to fix shift those connector slots!

[Sayanee @sayanee_]

The 3D printed box has arrived 🎁

Very happy that the connector and PCB fitting works for my first designed case! Waiting for the M3 self-tapping screws to arrive now 😌

[Sayanee @sayanee_]

Neat! I guess this will also work for 3D printing electronics enclosures.

[Gavin Nelson @Gavmn]

There's actually a formula for this if you wanted to go a step further —

inner radius = outer radius - distance between outer and inner edge

@matseng Wow! I met him at Maker Faire in Singapore in 2014/2015 I think. Inspired me with Dangerous Prototype work!

I am just trying to delete some old Glacier instances I created 9 years ago and am paying $0.09 per month.

Maybe I shouldn't bother and just pay ~$50 for my entire lifetime 😅

[Jason Lengstorf @jlengstorf]

Every month I pay AWS $1.43 and I have zero recollection of how or why but I’m too lazy to dig through the AWS console to figure it out.

[Sayanee @sayanee_]

@shannietron @ntt @PCBWayOfficial Thanks! Yeah. in the end, it's all about trial and error and it's my first case!

It's for the outdoor use case, but I won't be using it for hours and days outside exposed to the weather.

I'll go with Resin then.

[Sayanee @sayanee_]

@avinash_pudale Thanks a lot! I indeed wondered how to create a separation plane with those bends for the slots.

[Sayanee @sayanee_]

@avinash_pudale Links, please :) Would love to know more about what is Subshape!
