One way is to use something like this https://www.pololu.com/product/2842.

I love the DIY flavour of your solution! Congrats on getting it working.
I can recommend the Pololu voltage reg's too; I've used them on a couple of projects and they're great - small, efficient, stable and relatively inexpensive.

Thanks for the pointers. I'll let you know how it works out (in probably another couple of months!)

3v from 5v can easily be achieved with a voltage divider made up of a 3k resistor and a 2k resistor. Connect the 2 resistors in series between gnd and 5v. The voltage across the 3k resistor will be 3v and similarily 2v across the 2k resistor. Because the current drain of a microbit is a few milli amps and a voltage divider uses no power. This solution will only cost 10p
