I decided that if I was going to get into electronics I better do at least one project using an altoids tin. Also I really don't have a good power supply (an atx supply with a mess of wires doesn't count), so I figured I'd make a portable power supply with some common voltage rails. + +Thus, this project was born. + +## Main Goals ## + +Battery powered PSU with common voltage rails (for me at least). + +Must have features: +- 5v rail. +- 3v3 rail. +- Battery and a way to convienently charge it (USB) + +Wants: +- 12V rail. (I don't know why) +- 5V USB output (as a phone charger) + +I also wanted to learn about switch mode power supplies, so I used two MC34063s, one for the 5V and one for the 12V. (EEVBlog's tutorial was INCREDIBLY useful). 3v3 works better as a linear supply because you don't have to drop too much voltage. + +Li-ion charging is also a new thing for me, so this will be a learning curve. + +That's really it, most of the specific relevant information is on the schematic. I haven't finished the layout yet, but that's coming soon. \ No newline at end of file
