Embed Subtitle into Output VDO with AviSynth

If you want to embed *.srt subtitle into output VDO by using AviSynth:

1. Download VSFilter from http://www.animereactor.dk/aegisub/
2. Extract vsfilter.dll to folder C:\Program Files\AviSynth 2.58\plugins\
3. Add these commands into *.avs file:

LoadPlugin("C:\Program Files\AviSynth 2.58\plugins\VSFilter.dll") TextSub("filename.srt")

If audio and video are not sync'ed together, use these commands to split them, and then adjust audio delay.

V = DirectShowSource("video.mp4",fps=25.0,convertfps=true) A = DirectShowSource("audio.aac", video=false) AudioDub(V, A) DelayAudio(-0.500)

Induction Cooker

I've just bought an induction cooker from BigC. It's Hanabishi HIC-20EA 2000 watts, 1700 BHT.
My sister bought another induction cooker from Lotus for only 900 BHT. It's AJ brand. Sooooo cheap (T_T)

You can find more information about the induction cooker from Google.

Power Amp Class-D (part 2)

I went to Baanmooh today gain.
At first I am going to buy two of Power Amp Class-D 20W
But I saw this, Power Amp Class-D 12+12W, 690 BHT.

12W+12W CLASS D Specifications 1. 12W/CH, 8 Ohms Load at 15 Vcc 2. No Heatsink 3. 32 Step DC Volume 4. Vcc 8-18 V 5. Imax 2 A at Po 12 W 6. Shutdown 160 uA

It uses digital volume control to adjust both level simultaneously.
So there will be no noise generated when the volume got dirt.

No pop/click sound generated when turning on/off power switch.
(The same as 20W.)

I have measured its power consumption:
- No sound, 15 mA
- Playing at normal level, 25 mA
- Driving SubWoofer speaker, 125 mA

Modify Car MP3 Player (part 2)

Oops! I did it again... errr... I mean I bought it again.

A Car MP3 Player, 220 baht, with a new circuit design. (But the same crap sound quality)
So I added an antenna and 2 capacitors to add more treble.
Now its sound quality is better than some radio stations. ;-)

- Antenna, use thin wire about 36 cm. long.
Then soldered at ANT label.
(I forgot to take the photo)

- Use 2 small 0.0068uF capacitors, then soldered into the space as shown in photos.
(I found only the big one from my spare)

- Use cutter to cut the plastic filter between LCD display and infrared receiver.
(Don't know what's that filter for)
