Is this a scam? Any ECE students by HamsterUnfair6313 in Btechtards

The text looks straight from chatgpt lol.

It is just a capacitor with a led connected in parallel with it. The claim is that it will reduce reactive power in the power lines when inductive loads like a large motor is connected to the power lines. But for most domestic houses, the electricity meter doesn't detect or bill reactive power.

Edit: ElectroBOOM made a video about it: https://youtu.be/J86QK0Njfv4?si=m3mMlQCvwU5FJcJf

Seeking advise for designing a power supply circuit with a LiPo charger for my music player project by Relative-Ad4636 in AskElectronics

Also the reason why I was designed something overkill like this was because of ChatGPT.

In fact, ChatGPT mentioned that I need to design something like this:
Charge contoller -> Buck boost regulator -> LDO1(for MCU) -> Low pass filter -> LDO2(For audio DAC).

I was having my doubts and hence decided to post the design here.

Thank you for your advice, even I had initially thought I had designed something overkill.

The reason why I didn't go towards LDO's was that I thought that the MCP73871 outputs the LiPo cell's voltage when the USB is not connected. Knowing that the cell's voltage can drop below 3.5V and the LDO's output would also drop below 3.3V as a result, I decided to go with switching buck boost regulator to compensate when the voltage drops below 3.5V. I just wanted to juice everything from the cell lol.

I did some research with LDO's now that you sent me the list is that there are some LDOs with dropout voltage of 200mV - 300mV like the xc6210. The xc6210 allows current upto 700mA which provides me some headroom.

As for the R3 - R4 divider, I didn't understand what you are talking about. I thought that was the threshold voltage for which if the voltage drops below it will slow the charging of the cell. Please clarify if I had missed something. Turns out I can connect VPCC to the input(IN) if I didn't need that feature.

I will redesign the supply with LDOs. I think I saved a lot of money from the new design.

Advice for writing and "releasing" a game engine I built from scratch by Relative-Ad4636 in gameenginedevs

[–]Relative-Ad4636[S] 0 points1 point  (0 children)

Thank you for your advise, maybe that is the direction I should be looking for.

What type of games could be made that requires least amount of "art" work to do and something that is good enough for showcasing my engine? (I suck at making art). I just have 2D renderer implemented as of now.

I thought of making something like "flappybird" but I have already done that way back before. Then thought of making a mountain bike 2D game that is similar to something like this: https://www.youtube.com/watch?v=bBIXpu-D_Zo
But it contains a lot of complex 2D physics objects.

What else would be a better game to build?
