I found some additional info about STi5518: Overview The STi5518 is a highly integrated single-chip decoder, designed for use in feature-rich mass-market set-top boxes. It integrates a high performance 32-bit CPU, a dedicated block for DVB/DirectTV transport demultiplexing and descrambling, modules for MPEG-2 video and audio decoding with 3D-surround and MP3 support, advanced display and graphics features, a digital video encoder, and all of the system peripherals required in a typical low-cost interactive receiver. To cover the needs of DVD-capable set-top boxes, STi5518 integration options include a CSS decryption block, a Dolby Digital audio decoder and Macrovision copy protection. An ATAPI interface support is built-in, supporting the glueless connection of standard Hard Disk Drives. In this way, the STi5518 is ideal for set-top boxes featuring trick modes such as live TV recording, pausing and time-shifting. The STi5518 is backward compatible with the popular STi5500 set-top box decoder, allowing easy migration from the previous generation. The high level of integration in a single PQFP-208 package makes the STi5518 ideally suited for low-cost, high volume set-top box applications Features Integrated 32-bit host CPU @ 81MHz 2 Kbytes of instruction cache, 2 Kbytes of data cache, and 4Kbytes of SRAM configurable as data cache. Audio decoder 5.1 channel Dolby

I can't know what's is wrong. I suggest you to test the connections very-very carefully.

IC2 is correct but IC1 is: 8765 1234 You measure pins as the folowing image indicates. Also you can search the net for datasheet of the IC you are using.

MERRY CHRISTMAS

Check here: http://www.sony.co.jp/%7Esemicon/english/90230.html There are many datasheets for CXA series but i can't see the CXA1110AS/B you are searching for. Maybe there is a suitable.

That's great News!! I split it in a new Topic so it will be more accesible.

Also here is a circuit on how to use it:

I was amazed when i read it also.. but i haven't try it yet. Maybe because it's glossy paper the toner doesn't stick well on paper and it's transfered to the copper when you iron it. Send him an e-mail and ask if this method really works. Don't forget to inform us!

Hello Here is the datasheet of this IC: Download It's a voice record/playback IC Hope that helps you.

Here is also a list of DC to AC converter and UPS circuits, so you can take some ideas! http://www.epanorama.net/links/psu_dcac.html

MP answers you exaclty what you needed :D ! I give you some nice links also: Uninterruptible Power Supply (UPS) FAQ http://www.jetcafe.org/~npc/doc/ups-faq.html DC to AC inverter and UPS Page http://www.epanorama.net/links/psu_dcac.html

There are some solid state relays that at rated at 25A or 40A. If you find a relay of that amperage everything will work nice. Check this as a reference: http://www.aeonelectric.com/aeon%20electric/ssr/ssr.htm

I made a little research about USB to IDE project and what I found follows. Many semiconductor companies have chips that do the conversion between IDE and USB and simplify the way you can connect an IDE device on USB, but you will need to draw your own schematic according to the datasheet and the application guides of each company. Here is a list of chips that do the work for you: IC

You just install it and it runs as system service. So there must be a problem with your connections. Just recheck carefully.

Today i received a report from a user from Argentina that build this power supply and it worked in his first attempt. Also he made the following modifications: "Replace R2 and R3 with 1/2W resitors, R2 heater, R7 with 10W resistor and R1 with 2-3W, C1 for 4700 uf, P1 is a many-turns wire-potentiometer (10 turns), and P2 is a "cermet" single-turn."

Here are some instructions to build a ground plane antenna suitable for FM transmitter: http://www.geocities.com/tomzi.geo/antenna/antenna.htm You can also use some other kind of antennas like dipoles. Here are some links with instructions: http://www.kyes.com/antenna/build.html http://www.kyes.com/antenna/antennadex.html Also check the attachment! Antenna_instructions.pdf

Hello Staigen You can freely upload them in a file (zip or anything else) here in forum like a message's attachement. The max allowed size is 1MB, hope you don't need more. Make a reply and under the message box is an "browse" button. Add the file there and click "Post". Wait some time to upload the file and then you message will be readable all over the world :D !

If you are searching a single chip H-Bridge rated at 3A/55V you can try : LMD18200T Datasheet LMD18201T Datasheet L6203

Right, you use the same 4 diodes to build the bridge. Here is the datasheet of 1N54XX: http://www.onsemi.com/pub/Collateral/1N5400-D.PDF The 2A diode means that the diode must be 2A or more. The 1N54XX are 3A so it's ideal to use them. Also the RAX GI837U is an alternative diode or bridge rectifier that seems to be hard to find it.

Are you ready to build it :o ?? Here you will find some great Hight Voltage Power Supplies using a TV's transformer: http://www.geocities.com/CapeCanaveral/Lab/5322/hv2.html

It's just for educational purposes :D ! But... it is used also to ionize your room.. so you don't have to buy a commercial ionizer to keep your room's air fresh ;D!

Great work EDY !! You won an ION MOTOR CONTRUCTION GUIDE ;D : Ion_motor.pdf

I suggest you to visit the author's site here: http://home.maine.rr.com/randylinscott/ and email him with your questions. The transistor tester is here: http://home.maine.rr.com/randylinscott/nov97.htm Don't forget to post the results and what caused the problem!

History of the Link Designs The Original 2 Phone Link Design is the updated version of the very first Link circuit that I designed for Silicon Chip magazine here in Oz, back in 1996. It was a bit hardware heavy, (nd therefore expensive for what it would do) having two heavy duty relays and two by two transistor oscillators, for ring tone and ring impulsing. These items have been replaced with optocouplers and an NE 556 dual timer chip, as per the rest of the Link cicuits. It provides for basic communications between two phones only, and there aren't even any numbers to dial. This being the first cab off the rank back in 96, there soon followed some requests for more phone extensions, and so the second Link design was 'born' and published in SC mag in June 1997.This version needed pulse dialling to access more than two handsets, and this was where the 'fun' really began. Trying to use phones that had been designed back in 1964, with garden variety '$2.00' off the shelf electronic chips and 50 cent components, proved a headache for me at first. After I learned a few tricks (mainly correct biasing, filtering and timing techniques) the rest became rather simple. After that second success, the need for an outside line materialised, and this was accomplished by using the 'recall' buttons (usually used by PABXs to access the outside line or special functions,) built into those old 800 series dial phone handsets here in Oz. While this would have worked for some, I couldn't guarantee to a worldwide Internet audience that the wiring would be the same in handsets availabe to them, and so another approach was needed. Remote control applications were also a consideration, ande were more easily achieved with DTMF than with dial pulsing techniques. Dialling a special access code (like a '0') to get the outside line obviated the need for an extra hard wired button, and saved on wiring, reducing the arrangements in the more advanced pulse dial Link from six wires for each handset, (two for speech and dialling, two for ringing the buzzers and two for the recall button) down to two wires for the next DTMF version, the A2B+1. Modifying this circuit again for internal use only, has produced the Link 4+0, which will be the last in the series (for now, anyway.) there are crosspoint matrix CMOS chips that can be used in conjunction with PIC processor chips to go beyond the limitations of these simplistic circuits, but I'll have to leave that area to more knowlegable people that I. Thanks once again Mike, for helping me get these designs on the Net, and I do hope that many people out there in Cyberspace will use them for their own needs, without all the hassles I went through to get this far.
