Samba Server on Android Media Player

I recently bought an Android-based media player: the Minix Neo X5. It came with the original firmware, which had issues playing the MTS video files that my digital camera produces, so I promptly upgrade to the latest ver 011 of the firmware. That solved the MTS playback issue, but the firmware itself was not very stable and hang quite frequently. So I promptly installed Clockmod Recovery, followed by the CWM version of Finless V1.2b. Now everything is fast and stable!

Next, I needed an SMB server on the media player so that I can manage its content from other PCs in the house. Surprisingly this turned out to be harder than I thought given the hackish nature of Android.

SambaDroid was quite easy to install and work with. Unfortunately, it does not support files > 2GB in size. This is quite a major limitation given than many media files these days are > 2GB in size.

Samba Server turned out to be a dud. Despite having root access, I couldn't set it up so that it is accessible by other Windows PCs. I even performed some registry hacks to enable legacy NTLM without any success.

I had partial success with Samba Filesharing (V1.0.6) and it supports files > 2GB, but I could only get it to work occasionally after a lot of coxing. Turns out it does not yet support Jelly Bean, so the app crashes the other 99% of the time, even with the samba-rc hack.

With no other candidates to try, I tried hacking into Samba Filesharing to see if I can make it work better with JB. Armed with adb shell,  I found that the Android version of smbd and nmbd are found under /data/data/com.funkyfresh.samba/files and can be started by running:

> sh ./samba-rc restart

But the app itself interfered with the operation of the daemons. Perhaps it is trying to control them and ended up crashing/killing the daemons. Anyway, the conclusion is that there is a fully working version of Samba included with the app. It's the app itself that is incompatible with JB. The app is a wrapper that receives events so that it can start smbd and nmbd when the network is up, and kill the daemons upon user request or when the network goes down.

So what I ended doing was:

1. Install and configure Samba Filesharing. This properly configures samba-rc and smb.conf.

2. Perform adb pull /data/data/com.funkyfresh.samba/files. Then update samba-rc by adding a single line.

3. Uninstall Samba Filesharing. This gets rid of the app itself so that it does not interfere with the daemons.

4. Manually create /data/data/com.funkyfresh.samba/files via adb shell.

5. Zip up the files and upload via adb push. The zipping is necessary because adb push can only handle individual files. Then adb shell and unzip.

6. Perform chmod 0777 samba-rc smbd nmbd.

Then I try to manually execute sh ./samba-rc restart. This started the smbd and nmbd daemons and I was able to connect to the shares from another machine.

Now this left the problem of running the script when the machine starts up, after the network interface is brought up. The simplest way I found was to use Script Manager. There are probably other ways (eg. via DHCP hooks), but I am lazy and went with the simplest method that worked.

I am sure Samba Filesharing will eventually be updated to support JB fully. There is a very active thread here on xda-developers for this purpose. But in the mean time, if Samba Filesharing does not work directly on your device yet, I hope my experience here is of some help to get it working on yours.

Cooling mod for the X96 Air #2

Previously, I added a USB cooling fan to the X96 Air TV box . The problem with this mod is that the fan is always running, and it runs at full speed. Ideally, the fan should kick in only when the CPU temperature is above a certain threshold. It would be even better if there is a way to control the fan speed. Dan McDonald left me a comment pointing to his project on Github . He basically connected the fan to a USB relay that can be controlled by Python script. His project inspired me to make a similar mod that would make use of the spare D1 Mini boards I have lying around. The plan is to hook up the fan to a MOSFET (2N7000) and control it via PWM. Here's the very simple circuit: The code simply reads a single character from the serial port (0 - 9). 0 will turn the fan off, while 1 - 9 will generate a proportional PWM to drive the fan, with 1 being the lowest and 9 being the highest. Here's the Arduino code: #include <Arduino.h> void setup () { Serial . begin ( 9600 ...

Installing and customizing CoreELEC in X96 Air

I previously installed CoreELEC on another TV Box ( Ugoos X3 Pro ), which unfortunately died after only 9 months during the summer (due to the unit overheating, which I learned is a common problem for cheap Android TV boxes). So this time I purchased a X96 Air  (4GB/32Gb) and had to do the whole thing again. So this is a note-to-self in case I ever have to install CoreELEC again on some other device. Installation of CoreELEC is simple enough by following this guide . Basically, it involves downloading and writing the firmware to a microSD card using usbimager . Then insert the microSD card, reset the unit and hold the reset until the logo appears. The unit will then proceed to boot into CoreELEC. First thing is to connect to WiFi, then enable SSH. This allows me to login via ssh and execute: ceemmc -x from the terminal. This writes CoreELEC to the built-in eMMC storage, after which I am able to remove the microSD card and reboot the unit into CoreELEC via the built-in sto...

DC-DC Buck Stepdown Converter for ESP8266

I am working on a project that requires a step-down converter from 12V to 5V, that will then power a WeMOS D1 Mini. I saw this new mini buck converter based on the usual LM2596 MP2307 , so I thought I'd give it a try. Unfortunately, it didn't work. Although it is supposed to be able to supply up to 1.8A, the D1 Mini was not able to boot up. The 5V pin was being properly supplied, but the 3.3V pin measures at only ~1.3V. So I had to go back to my usual LM2596 module, which is much larger, but works to power the D1 Mini with a 12V source. Here's a great review of the mini buck converter I found while trying to figure out how to make it work. The fact that it has high quiescent current (~60mA) is also mentioned in a few other sources.
