Amp and USB Chargers

This is a good article that explains how USB charging works. Basically, avoid cheap chargers. For any reasonably good charger, the amperage of the charger doesn’t really matter so long as it exceeds what the device requires; that is, use a charger with at least 0.5 Amp if the device requires 0.5 Amp (what the original charger uses). Thus, it’s OK to use my 2 Amp chargers on most of my mobile device so things charge faster!

WiFi Tether on HTC EVO 3D

Owned my HTC EVO 3D (rooted, stock rom) for almost half a year already and I have not gotten WiFi Tether working until now based on this post. I’m currently using version 3.9 Beta 9. To get tethering to work, I need to enable MSS clamping and Routing fix under Menu > Settings per this post. Yay! I can now tether when I’m away from home.

Access or stream remote files on Android using EStrong File Explorer

I currently use AndFTP to download files remotely using the ftp or sftp protocol. For local file access, I use something like ASTRO File Manager or Linda File Manager. I recently discovered EStrong File Explorer, a file manager that lets me access both local and remote files. You can access or stream remote files directly without downloading it first. That is, you can select an mp3 file and play it with your favorite music app directly. It is like the remote server is mounted on the device like in Linux which makes file access feel seamless. Too bad streaming movie files like XviD is a little laggy with MX Video Player or Rockplayer Lite even when the server is on the local network.

Offline maps for GPS on Android without a need for a data connection

To follow up on my recent post about Navit, a cross-platform map and GPS program that you can use on your laptop when on the road, I did a search for map/GPS programs on the Android platform that do not rely on a data connection. Like I mentioned in my previous post, I sometimes travel to locations where I do not have cellular signal (like in the mountains), which render Google Maps and my phone’s default navigation software useless. GPS signals are usually available as long as I’m outdoors (based on my personal experiences), so I hope to rely on a device with a GPS receiver with maps stored on it.

For the Android platform, I discovered MapDroyd and CoPilot from this thread. MayDroyd makes use of OpenStreetMaps like Navit and tangoGPS, and hence is free. CoPilot costs money.

To store map data on my phone, I’m going to need to buy a bigger micro SDHC card (32 GB?) since the entire planet data is over 6 GB and the Americas is over 2 GB.

Send and receive your phone’s SMS through Instant Messages

I read this post and found out about TalkMyPhone, an Android app that let’s you send and receive SMS messages from any instant messaging program such as Pidgin via the jabber protocol.

It comes in handy as I don’t like having a long conversation via SMS when a computer is in front of me; I can multi-task on the computer like I usually do without having to take my hands off the computer keyboard.

My setup is as follows:

  1. Register for an account on jabber.
  2. Make sure that this account is friend’s with my gmail gtalk account; done by IM’ing the gmail account from this web app (didn’t work in Pidgin).
  3. On my computer, sign on to the jabber account from 1, eg, through Pidgin.
  4. In TalkMyPhone’s settings, set to notify the address from 1. Leave the default setting of unchecked “Use a different account” (the phone’s google talk account will communicate with the account from 1).

I really like it, but I have a feeling it will eat up battery pretty fast. Since I’m in front of the computer, just keep the usb port plugged in for charging. Enjoy!
