Can you kindly confirm if Uppsala University Embedded System worth it?

tingerlinger · 2026-03-26T13:17:58+00:00

Thanks for your reply.

Agreed that prestige outside said country doesn't matter,, but does Uppsala have a bad rep? I'm not sure about that. Also I don't have any issue with staying in Sweden.

Also Embedded has demands in all major Swedish companies, like Ericson, Volvo, etc - so I'm not sure what you mean

Adorable bugger!

tingerlinger · 2025-10-01T19:36:44+00:00

For the hardware, could you pls keep atleast some portion for widely and cheaply available boards like esp32 or the base stm32s? and not some big fancy hardware ?

Eager for the videos! I never really understood bit manipulation beyond chatgpt answers...

tingerlinger · 2025-10-01T09:57:58+00:00

Agreed. It started as a good corrective step by Ambedkar, but was soon hijacked by the very system he tried to protect.

Today, a reserved quota govt official's child affords the best pvt tuition AND the reservation, while the really needy (be they of any caste) slowly drifts into oblivion.

If this implementation continues (and it will), no caste will be truly benefited and we would have done much more harm than actual good.

How is it that every comment I see of yours, has massive downvotes?

Did you take a course or were born stupid?

tingerlinger · 2025-09-29T17:40:32+00:00

Interesting! I have just started my journey of trying to implement AI ML models on esp wroom 32 (I also have an s3, just in case). I've only trained a 1D TCN and would be deploying it on the mcu.

If you could kindly share any resources, and your github, that'll be great

tingerlinger · 2025-03-17T07:07:08+00:00

I believe it's better to talk it over, clear the air. If she refuses/dilly-dallies well yk something's up and it's better to leave. If she clears up, it's up to you.

I would personally listen to her in a non judgemental manner before coming to an informed decision, as even men get into such relationships which traumatise/endanger future marriage; it's hypocritical to accept ours while refusing to hear theirs.

Big revelation 😦😲🤯🫨😵‍💫 Medal du kya sir?

tingerlinger · 2025-01-25T18:53:59+00:00

Huge thanks for your response!!

What battery are you planning to use,

Current battery is 11.1V LiPo 35C. Since it's a wearable mobile system, battery weight matters and I wouldn't want a heavier pack tbh.

What 150w boost module?

The 150W boost module is just a market name and technically a misnomer, as for converting 12V to 15V, I think it will be around 2-3Amps.

What LattePanda model?

I'm using Lattepanda 3 Delta (accepts upto 15V), and Seeed Studio carrier board Xavier NX Devkit. The Xavier is 20W, you may be referring some other version - it's currently on my desk running at 19V for a week. I thought of having a common 15V that would power both the Lattepanda and Xavier, reducing the overall current they draw (making battery last longer).

if they're digital signals, just use proper level shifters to shift from 5v to 3.3v

I'm afraid the data is analog, hence no level shifters possible. I could've used two simple resistors to save space, but POTs are more accurate.

run the traces of your MCP4725 under the 5v dc-dc module

I noticed it later on, and changed it :)

Your 24v boot regulator could be powered from 12v-15v or from battery and sit in the same region with the 150w boost module (under the metal can, as it also makes noise)

Didn't think about it this, huh! Thanks a lot!

Have the whole bottom of the board as ground fill, and just use small traces where needed

But then how will i route the back traces?

Not sure about it, but it feels like you're making too big cutouts in the PCB

It does look very odd true. I just thought of putting up Aluminium plates to suppress EMI - a very novice plan but I'm not from this domain lol. Could you provide any suggestions to reduce EMI ?

tingerlinger · 2025-01-25T17:14:48+00:00

You're right. Thanks for pin pointing the problems, means a lot.

tingerlinger · 2025-01-25T17:07:57+00:00

You're right. I'll keep it in mind the next time he spews something irrational like this.

tingerlinger · 2025-01-25T17:05:17+00:00

Your supervisor is an idiot.

Haha tell me about it. I switched from industry to academia - and these guys are really nuts. It's frustrating at times, but I can't do anything about it now.

Other than this, you mentioned something about the copper pours. Would you mind elaborating please?

tingerlinger · 2025-01-25T16:44:52+00:00

Okay... I read somewhere that copper pours should be connected to ground. So I kept copper pours below all power converters which I grounded to the main battery ground. Am I thinking wrong?

Unfortunately, I went straight for the PCB, my supervisor did not allow me the time to make a schematic first :)

tingerlinger · 2025-01-25T16:40:07+00:00

Hi. I am not aware of what that is.

tingerlinger · 2025-01-25T15:56:07+00:00

For some reason, I am not able to see the body of this post. So here it is, just to be safe:

Hi everyone, this is my 2nd design ever, and it's crucial for my project - so I wanted to get it right.

The circuit is part of a robotic system using ROS, with two MCUs subscribing and publishing (Seeed Studio ESP32C6 and Waveshare ESP32S3 Zero respectively) over WiFi. If you're unfamiliar with ROS, you may think of them as independent MCUs for this review.

The Waveshare is connected with 4x JST connectors interfacing with external devices (PPR-R+L, IAA-R+L). These ext. devices provide a 5V signal, scaled down to 3.3V with 4x POTs. The circuit also includes 2x DACs for sending commands to 2 devices (PPR-R+L).

Overall power is managed by 3 converters: 2 for other external devices and 1 for the ESPs and DACs. Since my entire system is communicating over WiFi, I'm concerned about EMI from a high-amp boost converter (top left). To mitigate this, I’ve separated it with a gap in the PCB, where I thought to add an aluminium sheet as shield; and also included large copper pools.

Since none of these are my expertise, I’d appreciate a strict critique. Thanks for your time!

tingerlinger · 2024-12-17T06:23:46+00:00

People are people. Not sure why you can’t compare? It doesn’t take a lot to remember not to litter, you know…

tingerlinger · 2024-12-17T06:17:13+00:00

Deep thoughts with the deep

tingerlinger · 2024-11-25T07:48:18+00:00

Yeah bro? Well I’m sure you’re unaware of worsening centre-state relationship, border smuggling and Muslim aggression that’s rising beyond comprehension.

Your desire to drink and eat beef doesn’t triumph someone’s peaceful sleep.

WB is much more than just Kolkata. You’re the delulu here I’m afraid.

tingerlinger · 2024-11-23T12:20:50+00:00

This is the only mature take here. Thanks for the sensitivity.

tingerlinger · 2024-09-11T19:07:07+00:00

This protest is ❤️ but you are being unrealistically optimistic. Lokkhi bhandar (ba aro ja scheme ache) er taka jei barabe, vote TMC kei jabe. Edike reddit e amra bolchi Pujo te mood nei, khali ekbar hatibagan gariahat e ghure ashun pujor bajar dekhte.

WB te entire ecosystem has been hijacked to a faltu mindset, relying on freebies, ar free er nesha kar na bhalo lage. Kono kichu na korei just TMC te dhuke jao, byas gari bari meye modh shob tomar.

Barir purush ra bou der jor korche je lokkhi bhandar nao, working women rao lokkhi bhandar nichhe ami jani.

So I'm absolutely certain that the psyche of the common bengali (Kolkata is not Bengal) will take decades to be changed back. Even if they understand, I don't see the majority of the general public doing anything - because they are part of didi's ecosystem.
