These step-down modules are currently available on ebay for about 40¢ per piece (pack of 20). Input voltage 5V-23V output a bit lower. 3A continuous current, 4A peak. They DO require an additional output capacitor to run stably.

Well... at least PDI programming worked. I still need to get a micro-USB cable.
Today I found out that my local consumer electronics store thinks I should pay 16€ for a friggin' 1.8m micro-USB cable. NO WAY. The cheapest old-style USB2.0 cable was still 6€. WTF!?! Up till now I was happy with HDMI cables being hilariously overpriced (I don't need those), but simple micro-USB cables are now overpriced as well.

Soldering was pretty relaxed, except for the USB socket. The 0603 components require a bit of concentration and patience. Soldering with an iron is possible for enthusiasts, a magnifier would help a lot. Using solder paste + hot air / oven is definitely the way to go if you do more than just one board.

Same charger as seen on the latest EEVblog video #284 .
Looking at the waveform you can see that I put my "pickup coil" on the charger the other way around.
Done!

A bit too much solder on the metal body, but that doesn't matter. It's hand assembled.

A sheet of soft tissue soaked with isopropyl alcohol and a stiff brush works nicely.
