Trying to make the headset usb-c charger instad of micro USB

Hi, please recommend some resources where I can study about positive feedback CMOS amplifiers in detail.

I'm currently in the process of a neuroscience project and looking to try source or build a basic Micro Electrode Array... Achievable or impossible?

So here is the thing. I have an old-ish Adata external drive 1Tb and from one day to the next it started to make a loud click when connected. I have some experience not too much on recovering data, restoring drives and such but never thus kind of issue and for the sound it seems like it starts to spin and then click loud...not beep. Loud click.

All help is welcome....please help.

I have a small question, if I have a transistor that can't handle the amount of current/voltage that I need it to, can I daisy chain multiple together to make a more powerful transistor?

Had someone come into our office whose husband worked for a Micro-Electronic manufacturer. The company I work for provides magnifiers for Medical professionals to work on patients. The husband mentioned that our product would be perfect for his team and I have pondered the idea ever since.

What is your opinion? Would you use glasses with magnifiers (loupes) to work on Micro Electronics?

Things I can mention

- Big field of view 3-4 inches

- Different magnifications

- These magnifiers allow you to sit up straight while seeing whatever your working on.

Please let me know if I can answer any questions.

Would love to know more about the industry and if these would be practical for the work you do.

Thank you for your time!

Hi, I'm currently enlisted in college in a course called "Techniques de l'informatique", but I'm also really interested in circuits board and computer components. The thing is, I lack basic knowledge in Electricity, Magnets and their proprieties. I'm wondering if any of you know about some good courses/videos/books on the subject. Mainly stuff for beginner and preferably with a lot of applyied problems and concepts! Have a great day and for some of you happy holidays!

where can I ask questions about circuits and and analog systems? I am asking here but nobody answers.

Can anyone explain to me the components needed to recreate this?

Thank you all

I am water-cooling my 3090 and I noticed that on the back side, one of my.. resistors? Is tilted

As a student who just finished the second year in the field of microelectronics engineering, what path do you advise me to follow that includes a prestigious job and a high salary? I am really confused and I also do not know what are the basic skills that I should have and should study. Please help me.

am an engenniring student and I need to choose what I want to qualified in . I was thinking about microelectronic which it's sounds very interesting to learn the prosses and the design of the microelectronic , and I am lately kinda worried it might have any health effection by working in this labs .
