What do I need to start getting into electronics?
A 4x4x4 LED cube (just so I can know the fundamentals before jumping into an 8x8x8)
A stereo (I have 2 car speakers that are just laying around, I'm hoping to turn them into something useful)
Touching up my benchtop power supply (I built one out of a computer PSU but it looks.... not good)
A high-power LED flashlight (my mom is into photography and saw a post about using an LED for an improv light source--the pictures turned out great, so I want to build one that has enough brightness to be used in a real photoshoot)
An LED visualizer (This is one of the more daunting ideas I've had, I realize programming will be a bit difficult... I was hoping to use RGB LEDs and a microcontroller to handle the logic)
I have a bit of experience in coding, nothing too impressive, but enough where I feel that I can grasp at least the programming of an Arduino (which so far looks user friendly and relatively simple [to me]), and on top of that I've been into computers and done a bit of tinkering with electronics before and so I know the basics of resistors (and LEDs together), capacitors, relays etc. Any advice would be greatly appreciated :)
