DIY portable 12v/5v power supply.

Do you have a nearly dead UPS battery, a bundle of wires and $15? Why not to combine them into the PSU which will provide you both +12V and +5V to power almost full range of gadgets?

Check my post here for details. 

Unofficial GitUp Git2 Android app.

Seems like GitUp experiences some kind of problems creating Android application for Git2 action cam control. Moreover there is even no estimated release date stated at the moment. So I decided not to cool heels anymore and write my own code.

Here comes GitApp - an unofficial Android appliction for GitUp Git2 camera (actually can work with any Novatek based cam). It already can start/stop video recording, take video snapshot and open live stream from Git2 camera. Now it's in early beta status and I will release it as soon as I add some more features. Stay tuned!

Hacking Novatek firmware.

Just managed to unpack Novatek NT96660 .BIN firmware  file. It can contain one or two separate firmwares combined into one file: one for uITRON OS and one for eCos OS. Seems like one is for realtime user interaction and the other is for camera controls. Stay tuned.
