Joule Cell Rechargeable Battery by Gosh!

I know most electronics now comes with rechargeable batteries. However, most remotes are still powered by batteries. Although these batteries aren't expensive, they can still add up.

As for me, I'm playing Fatal Frame on my Wii (I know its old, but I WANT TO finish the game) and my wiinote eats up AA battery like a hungry monster. (Say, about 2 every 2-4 days)


SO I started searching online for an "solution" and I finally found the Joule Cell by Gosh!  They cost SG$1.90 per box!!


Joule Cell

NiMH (nickel metal hydride)1.2V AA Size (Comes with AAA size too, but the AAA ones I got was slightly rusty and defective ... but I'm too lazy to go down and get it change)
Charging Current: 5V/1100mAh
Charging Time: 8.5 hrs
LED Indicator: Red for charging; Blue when done charging 


In the box, they included a USB charging cable with 2 micro USB outputs and of course 2 AA batteries. (This cost SG$1.90!)

 In the picture above, I compared it to the usual AA battery. It look almost e…

Using Karaoke Microphone on your iPhone!

I guess its no secret that I'm always relying on the mic on my earphones to sing on singing application. However, I recently discovered that we do have some spare microphone lying around that we hardly use.




So I did some research online and discovered that its possible to use them with my iPhone and sing with them! There are a few ways to do this, the more expensive way (by getting a cable that connect the mic straight to your phone) or cheaper way by using adapter.

It's obvious which way I chose, right?

Anyway, here is what you need:

1) Microphone and XLR Cable (obviously) - $0.
If you already have a microphone, you probably have these already.

 


 2) XLR to Mono 3.5mm TRS - $1.

I'm no expert with these audio jacks and their segments. However, I realised that only those with one line will work. 

3) An audio split that works with iPhone. - $2.



Note that the number of lines should be as the photo. (3 lines) And you should get one that work with iPhone!


The audio split will have a connector for audio and one for microphone.


The setup is very easy.


You just need to connect the microphone to the XLR to 3.5mm adapter and then connect the adapter to the microphone connector in the audio split.

Then connect the whole setup to your phone jack and it's done!

If you want to hear the output while you sing, you can connect your earphone to the audio connector in the audio split.

As you can see, this setup cost about $3 only. (excluding the microphone because I already have one)

If you're wondering how it sounds, well I must say, it's very sensitive and you might need to sing in a quiet place or it'll capture a lot of the environmental sound.

I don't know about other people who can sing professionally, but I don't like how I sound with this setup. Although I like how I can have more control over that mic when I sing (like controlling the distance of the mic from my mouth) and there is little to no pop even when I blow into the mic.

Basically, there are pros and cons to this setup and it's up to you to try it or not.
