Thanks for the clarification! As I said, this is my thesis project for my BSc in Computer Science, but I’m definitely considering a more electronics focused masters, especially given the fact I’m already searching for a job in the field of embedded systems/low level stuff. Might be a good piece of paper to have in the future :)

Thanks, I just submitted a new order for a kit of assorted ceramic capacitors. The comments in this post have been really helpful with regards to the capacitor question, I feel I understand it more now. You people are lovely :)

Ive got one (not the one you mentioned) which is quite good. I don’t think its quite at the level of the one you said, but it should be decent.

If that’s the case I’ll turn this into an exercise. I’ll make a simple testing circuit once I’m done with my thesis and see how many I can save. Worst case I get some practice. Best case I get a set of switches for free and recycle. Most likely I’ll fry some, save others, and have a stock of spares and some experience. Thanks!

I wouldn’t call myself skilled by any means, but I have some experience with it, and have some tools available (flux, wick, etc)

Thanks it actually was quite helpful to understand why I need to use such a capacitor for my chips! (Until towards the end he started getting really deep into it and my eyes glazed over)

Am I correct in assuming that my project and the chips I use do not really require me to put 3 or 4 different value capacitors in parallel instead of just one? Also, he mentions that its a good idea to use this technique on all chips, so would there be a downside to me placing a (or more) capacitor on the Vcc pin of all 3 of my chips (RTC, LCD display, Bluetooth) even though their datasheets might not specifically mention requiring them? Basically, if I have the capacitors, is there a reason to not put a decoupling capacitor on the Vcc pin of any chip in your circuit?

As for the RTC’s 32kHz clock as you can see from my diagram I didn’t connect it to anything. I was under the impression that it was unnecessary for my purpose after looking at the datasheet. Am I wrong?

I see. A new question arose from reading your reply. Theoretically, if I were to put e.g. 2x1uF electrolytic (or any type) capacitors basically in series next to the power source of a chip, does that increase reliability or is there little reward for it?

Ok, I might be dumb, but I dont get the text on the top of the meme. Anyone care to explain?

Yes, I’ll probably just be doing this on breadboards, but there is a chance I might eventually move it to a PCB (assuming I learn that part of KiCAD soon enough and have enough time to order PCBs before I need to submit). In either case, the power source of the entire system will probably be some holder/rack (not sure what they are actually called) for several AA or AAA batteries. Basically it will need to be something that a theoretical consumer would be able to replace easily - the batteries that is.

Do the problems outlined in your and other’s comments about these types of capacitors in this application also present from regular batteries, or are they usually not high voltage enough to cause problems?

I think I understood what you mean, but I’m not entirely sure about the last part:

but reducing voltages spikes caused by high frequency electronics they don’t do much

In this situation, would the RTC module be the high frequency electronic, or would the arduino be it (capacitor to protect the RTC from arduino’s power supply??)

The datasheet just has this:

DC Power Pin for Primary Power Supply. This pin should be decoupled using a 0.1µF to 1.0µF capacitor. If not used, connect to ground.

But if it really is OK to use an electrolytic one given the polarity is correct, then thats still good. Ive been looking on online stores for 1uF ceramic capacitors and I couldnt find any.

No worries! Heres a link to their forums if you want to give it a peek for research

/e/os is a degoogled os, so not out of the box. Im not sure if you can opt to install them yourself later (why would you though) and i dont want to put any of that crap on this just to test it. The closest to a google thing it has is gApps, which is an open source implementation of google services.

Second this! Got mine from murena a couple days ago and its brilliant

I switched because of neovim, and got used to it. I was never the kind of guy to press caps to type capitals, always just kept shift pressed down with my pinky, so i basically never used the caps key anyway

Commenting because fellow caps-esc swap enthusiast, and I would like to know the answer as well

Could you elaborate on what you mean please?

Edit: I seem to be getting downvotes, so Id just like to clarify, I wasnt being smart or sarcastic in any way, just genuinely didnt understand what the comment OP meant xD

Dont go period. Even before this situation I was actively opposed to it. What people seem to conveniently forget is that the US didn’t suddenly become a fascistic empire overnight because of the election of one man. Its been like this, just less “in your face” about it. Most people only seem to care now because now there is a big negative effect on the USA itself as well as other western countries, but previously while it was some south-east asian, or middle-eastern, or south-american (you get the point) country most people conveniently turned a blind eye and just consumerismed.
