20 Band Audio Spectrum Analyzer

iPod touch

I found this tutorial on www.pyrofersprojects.com, it teaches you how to turn your iPod Touch (and iPhone) into a 3.5G iPhone! This is suitable for beginners as it involves no hacking at all of the iPod, and only a simple registry edit on the Windows phone.

What You Need
1) An iPod Touch or an iPhone.
2) A Phone/PDA with Windows Mobile 5 or 6.
3) A SIM card.
4) Download and install the free PHM Registry Editor onto the Windows phone. You can get it from www.phm.lu/Products/PocketPC/RegEdit/

After doing the procedure you don’t have to worry about the PDA, it will stay hidden in your pocket and only act as a mobile access point. This is a nice hack but it has its limitations, you cant really make a voice call with your iPod Touch because it doesn’t have a microphone. You should use a normal phone for that as it’s much more sensible for voice calls.

You can even use the PDA phone in your other pocket if you don’t mind looking like a complete dork holding a PDA to your head. Pyrofer also said that he successfully used MSN Messenger using the great web based messenger service, Meebo. It also allows you to use Aim, Yahoo and Google Talk, although he didn’t tested those yet. If you want to try this hack click the Link to visit de webpage.

USB Chocolate MP3 Player (2GB)     Although this mp3 player is presented with this name “chocolate” it’s not related to Samsung. Chocolate being such a common word, you can’t really brand it so the guys at usb.brando.com.hk offer for sale this cool mp3 player. It’s fashionable and stylish and it weighs only 12g. It only has 5 buttons (volume up, volume down, play/pause, forward, and backward). The mp3 player also has 4 color leds that blink in a cool way. Being available for only 39$ it’s accessible to anyone who likes it.

 

 

Here are some of the features:

  • Support MP3 and WMA playback
  • 4 Color LED
  • Tiny & Light

high definition earphones     These days its all about high definition, high definition audio systems, high definition video systems, etc. So why not have high definition on your mp3 player? The guys at XtremeMac offer you a product that I’m not entirely sure it is high definition, but certainly it will offer you a great quality. These earphones are fully compatible with ipods, in fact they are mostly for ipods. The package contains :

  • 1 pair of FS1 High Definition Earphones
  • 2 sets of pliable foam comfort sleeves (Small & Large)
  • 3 sets of flanged comfort sleeves (Small, Medium & Large)
  • Earwax removal tool
  • Zippered travel/carrying case
  • Instruction manual

 

 

 

And the specifications are:

  • Transducer: 10mm, Future Sonics MG5 Proprietary Miniature Dynamic
  • Input Sensitivity: +/-112dB @ 30Hz/1mW
  • Connector: 3.5mm (1/8″) standard stereo mini-plug; 90-degree angle
  • Noise Isolation: +/-25dB (using foam sleeves)
  • Impedance: 32 ohms
  • Frequency Response: 20Hz-20KHz

If this got your attention you have to prepare yourself to pay $149.95 for these earphones. They are not cheap, but their quality should make you buy them if you like high definition audio. Check their website for ordering details. Link

made-in-china-led     These days almost every project needs a led or two, projects based mostly on led’s may need more. So what can I do? I go to my local store, or I order from an online store, the parts that I need for the project. The bad thing is that most of the parts are made in China. I don’t have any problem with China. Is the parts that don’t work as they should that worries me. For example the LED’s I used in the earlier project “Changing the Ceiling 5w lamp from a car with 5 white LED’s gave me some trouble. I mounted all led’s correctly on the board but surprise, only 2 of them were working when I tested the circuit. The other 3 led’s were working backwards, so I had to take the project apart and mount them incorrectly so they can function properly. This is not too pleasant when it happens. So be careful if you’re using made in China parts and your circuits don’t work, you might want to check them.

I don’t really know if I need it to do this modification on my car… the 5w lamp was ok, but my 5 led circuit its more than ok, so don’t start this project unless you really need it or like it because your ceiling lamp is just fine as it is. Here is the schematic of the circuit, I’m not going to attach the board to because it’s a pretty simple circuit diagram so I didn’t design it with eagle; I did it by hand.

As you can see its composed of 5 white led’s, 5 resistor’s for current limiting a capacitor for a nice smooth turning off effect and a diode that doesn’t allow current to flow back to the car from the capacitor. The capacitor can be removed if you don’t like the smooth turning off effect or you can adjust its value to obtain the desired effect. I used 6900 uF and I have about 3 seconds of light after I switch off.

From the next picture you can see that I used 3 x 5mm LED’s and 2 x 10mm LED’s, that’s only because of what I had available.

You can use whatever dimension and color you like. From the picture you will also notice that I attached the capacitor with wires so that I can place it in a space behind the circuit (because the capacitor is large I don’t have room for it on the board). About the resistor’s I used they are 680 ohms and were calculated to fit my LED’s. It will probably work well for any LED I suggest not to use smaller then 680 ohms resistor, because you will burn your LED’s. If you would like to recalculate your resistor value based on your LED’s and voltage you can use this application http://led.linear1.org/1led.wiz . You will have to take in consideration that your car’s voltage may vary from 12 v to 14,4 v so make sure you cover this variation.

On the next picture you can see the 5W lamp socket. I’m going to connect my circuit to the lamp’s socket connector. In my car you can see that the casing its all plastic so it wont be a problem of isolation. But if in your car you place the circuit near metal parts you have to make sure that none of the board is actually touching the metal.

After doing that you can place de cap back over the new circuit with LED’s and its ready to go.
