TV out cable for Smart Phones

-



Many phones have TV out facility but the cable does not come in standard packaging box.
We have to buy it additional. It would cost hundreds for original cables

 I have made a TV out cable for my Nokia N79 long back. Same trick could be applied for other brands once you know the pinouts of 3.5mm jack correctly.

All you need is
1) 3.5 mm HEADSET connector with 4 contacts. ( u can buy headsets of china mobile phones having 3.5mm jack for that)
2) An old AV cable used to connect DVD players with TV(costs only 40 for new)

The microphone contact of the 3.5mm jack is used for carrying video signals to TV (for nokia). Other two contacts are used for left and right audio channels. The fourth contact is the common ground for video,left audio,right audio.

The contact line designations starting from the tip of 3.5mm jack is
1--right audio
2--left audio
3--mic (video: in our use)
4--common ground

Guys take up your soldering irons and assemble yourself

Enjoy videos and movie files on your big TV screens directly from your nokia phones

I have tested it with N79 and 5800xm





An update. See the below pic for some other brand pin assignments

Any types of cable that connect one device to another are called AV accessories. Almost every type of home entertainment set up required AV accessories for function. If you want to buy the best quality AV accessories then you can visit our site. AV accessories WA

Bidirectional 3.3v 5v Level Shifter

Hi guys.. welcome to another simple DIY project... Lets make a level shifter, which will just shift a 5v data line to 3.3v or vice versa... Okie why we need such a shifter..  ? or what is this stuff actually.... ? We run around huge bunch of devices that run in various voltage levels.. for example Raspberry Pi runs in 3.3v, and its all GPIO I/O pins are at this level, even though we provide a 5v USB input. And so it is not tolerent to 5V input levels from another device or sensor modules connected to it over I/O pins using SPI, UART, i2C... whatever.... Another example is Arduino UNO which runs in 5V, normally is driving all its I/O at 5V levels.  So interfacing boards at different I/O voltage levels requires a level shifter. Simple voltage divider circuits can help for an extent.. but they dont provide low voltage  device protection or bidirectional shifting. Wait a minute ... Bidirectional... what is it ? Okie.. some communication protocols like i2C are bidirectional,

DIY Fixing a Laptop Battery

Hi Friends ,  DIY is always fun and awesome, and so welcome to another word of tech byte... This note is a collective scratchpad of troubleshoot methods and fixes i came across recently for fixing my laptop battery that went bad. Battery Model   : HP HS04  battery pack (4 cell , lithium ion, 14.6V , 2670 mAh, 41 Wh) Laptop  Model  : HP 15-ac635tu   (equivalent to HP G4 250 Notebook) The Symptoms Laptop Showed 1. Laptop charger goes on and off intermittently after charging up to more than 60% . The charger port LED goes between charging and not-charging frequently. 2. Once laptop is running from battery, charge percentage drops faster than normal, and once it reaches 23% , laptop shuts off immediately. On power in on again the charge percentage will be less than 15% and wont complete bootup to desktop. Faints instantly. Troubleshooting 1. Borrowed a laptop charger from my friend and tried 2 or 3 charge cycles. But still the issue     persisted.     This confirmed that

USB-UART console using old nokia DKU-5 datacable. (3.3v TTL)

-
Image
Hi all.. lets do another beautiful DIY device... It will be a USB-UART dongle using Nokia Data Adapter DKU-5. What is it ??? A USB-UART dongle mimics a serial COM on PC. So... modern PCs lack DB-9 RS232 ports , but has plenty of USB ports. So there comes a lot of needs while you want to connect some boards ( Embedded linux boards, android TV boxes, Raspberry Pi, Beagle Board, FPGA kits, router/modem, HAM radio (ICOM/BAOFENG)  ) to your PC for low level debugging or programming. Since UART being the simplest of communications, all these board have a 3.3v or 5v TTL UART header to be hooked up... This header may consist of a Vcc,Tx,Rx,Gnd pins at one of above TTL voltages. So what we need to connect here is a UART- USB converter. Ebay can help you with cheap converters.. But it doesn't have the beauty of a DIY. So what i need ?? 1. Old DKU-5 nokia data adapter (CA-42 also works, but i had a DKU-5 only) 2. Some wires , soldering iron, strippers etc.. By luck CA-42
