Install web failsafe u-boot for WR703N


What is u-boot?

Moving Caption

I was playing Diablo 3 these days and I found it’s hard to read the name of the objects on the ground ’cause they are moving as I moving, so I wrote this small program to test my idea. (BTW, Diablo 3 sucks, not that big different from Diablo 2 and I’m wondering what is Blizzard doing in so many years…)

DIY shutter release

This is a idea/plan that I want to do.

Lately I brought a Canon 60D, and it’s cable shutter release is using 2.5mm audio jack which is a quite common and cheap so I decide to make one or more cable shutter release/s.

From the tip to the cable, there’s three contact point. Normally there are Left | Right | GND, as using on the 60D, they defined as Shutter | Focus | GND.

Things to do:

1. Build a manual shutter release;

2. Using Arduino as a controller so time-lapse photography will be much easier.Done

So far for now, I’ll update when I make something new.

Update: After installed the MagicLantern firmware to my 60D, it got the intervalmeter function, so it no longer need a outer controller to do the clicking.

Warcraft III Resolution Changer

This is a simple little program that make the Blizzard Warcraft III to fit your current screen resolution. Will you can do this by using the regedit yourself to modify the key: “HKEY_CURRENT_USER\Software\Blizzard Entertainment\Warcraft III\Video\” but this tool is much easier.

The program is in Chinese and I don’t want to change it but you can still pretty easy to use it since you only need to push one button(with the [确定更改] sign) once. If you really wanna use other language, please download the source code here: https://github.com/zhujunsan/Warcraft-III-Resolution-Changer

The program itself is at HERE.
