Hi, so I am trying to design a PCB that uses a 3.7V LiPo .

Taking into account how the voltage of the LiPo changes as it charges and discharges , I opted for a Buck-Boost Converter in order to ensure I always have a stable 3.3V. Perhaps this was not the correct choice , do enlighten me.

Online, I see a lot of guides for Buck converter LiPo charging help and Boost but I cant find it for Buck-Boost. So I've turned to Reddit for some clarification.

I want to know how any or this specific buck-boost circuit may affect the LiPo charging circuitry , E.G.

Are there any additiona

Saw a sizeable escort of two older range rovers on Mayo Avenue going towards south field lane .

Escorted by 3/4 police motorcycles and a large police suv?

Any idea who its for?

Im starting as an EEE in sept 26 , I'd like to know if UCL have anything available to engineering students in the format of a "makers space".

To be used in a way that is semi relevant to the course/ totally relevant to the course. Somewhere where students can exercise their hands on ambitions outside of delegated lab hours.

E.g. Access to soldering stations , electronic components , 3D printers etc.

Thanks.

Hyperfixation based arguments are ruining my relationship

Hi so to paint the picture, me (19M) and my gf of 3 years (18F) have always had an extremely close emotional bond. We have a lot of love for each other and an overall healthy relationship . Our friends and family on both sides are supportive as a result .

But theres always been issues linked to my autism that have created tension in our relationship. Empathy, me not knowing how to deal with overstimulation etc .

We have worked on these together and its what led me to actually getting a diagnosis in the first place. And these issues I found real solutions and coping methods for and we are all good with them now!

However, recentl

Hi guys, as the title suggests

I have cut open a usb c cable which is plugged into the wall with a 5V 10W charger plug .

Ive wired the LEDs VCC with the 5V of the usb C by twisting the wired together .

Same goes for both USB and LED GND which I have unified with the arduinos GND.

My leds are the 1m 60led W2812B which at full power are 18W , I did not expect to run them at full power but I expected this method would be sufficient to run it at the brightness I need. (Approx half)

In testing without the usb C as power , it worked and I was able to program 3 of the leds on the 1m 60led strip in a test run where everything was connected via a breadboard and i was using my arduino for pow

I want to drive the width of China and I want to do it in approx 30 days or less. Google says China is about 5500km wide of course dependent on where we start from but the general idea is west to east ending it in a big chinese city near the coast e.g. Shanghai .

The things I need advice for :

Which border to begin at e.g. (Pakistan , tajikstan etc)

Supplies

Car Hire

Danger zones or general areas to avoid etc

Hope somebody has any ideas.

I applied to 3 colleges , I was accepted by my 2nd choice college (2nd best) , but I have an interview to my 3rd choice (3rd best) college , is there any point in going now that I have been accepted by a better college , and that I don't want to go to the 3rd college anyway . BTW I have also done my 1st choice college interview.

I am in my mid teens and i frequently go to the gym . I came back home after a push day and I was quite tired so I laid down on the sofa . The next morning my mum started interrogating me about why I was tired (probably thinks I am lifting too much) . After that she started shouting at me threatening to cut my membership if I ever came back from the gym again tired , and banned be from going to the gym 2 days in a row . This makes no sense whatsoever because how am I supposed to do excercise without become tired???!?!!?? For reference , the most weight I lifted yesterday was 40kg on the bench for reps to near failure not total failure and that was only for 3 sets , everything else was less
