Hello,
I am interested in learning electronics and love audio systems. My goal is to take a project-based approach to learning electronics. Hopefully, backing into electronics from a high level to a low level by studying the components will prove effective. If I'm setting myself up for failure, please let me know (I appreciate constructive criticism). I'm decent at soldering, but my skills with high density, tiny components is limited.
I did some research regarding the required components for a stereo, but I'm not certain if I have everything. Online vendors assume a certain degree of knowledge (which I don't have) about the other components such as power supplies and transformers. I have inquired with various vendors and either did not getting a response or they don't know what's required to build a complete system (which seems strange). I'm hoping I can get feedback on my parts list and anything I may be missing.
My ideal stereo system (e.g. a boombox) would include multiple inputs such as a CD Player, Bluetooth for streaming and USB interface for mpeg files. Below is a components list that seems to be favored by many on the internet given the sound quality and low cost.
Other than speakers, does it look like I have everything to build a basic stereo with an external input (e.g. CD player)?
I believe I need a power transformer, correct?
Can this system be run off of batteries (for a portable system)? If so, any suggestions on what I need (e.g. rechargeable battery types, etc.)?
I'm assuming that I will need crossovers for my speakers, correct? Any suggestions?
Thank you for your help.
