Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int

How to migrate Django from SQLite to PostgreSQL

Dump existing data:

python3 manage.py dumpdata > datadump.json

Change settings.py to Postgres backend.

Make sure you can connect on PostgreSQL. Then:

miklobit

I had this really small problem today. I wanted to migrate one of my small django apps to use postgres, just to make everything easy to manage. Sqlite3 is perfectly fine for the amount of load, however I am really much faster at administering postgres than I am on sqlite3. So I decided to migrate the stuff over.

I tried a few approaches, but what ultimately worked the best and the fastest fo rmy particular problem was to do the following.

Use original SQLITE3 connection in settings.py
1. python manage.py dumpdata > dump.json

(I read some things here about some options you can pass, at the end what just worked was the following)

2. Change DB connection string in settings.py to POSTGRES
