Anybody know what this IC is at all ??
Need to get a replacement but can't tell what it's number actually is.
All I can tell is that it's some kind of switch mode controller.
It's out of my Sony KZ-32TS1E 32" Plasma TV.
It's on the main PSU pcb (PSE-324).
This is a not Sony's own...
Spring Connectors.....
Hi All,
Remember the old Tandy(Radio Shack) electronic project kits you could buy years ago ?, well I am after a number of those spring type connectors that they used to use for my current dev kit constructions.
Anyone know of any supplier for these at all in the UK...
Hi All,
I've got to drive a BSS138 FET Gate from an external source, via 2-3 feet of wiring, and inside a machine consisting of a couple of noisy mains motors and their mains wiring etc.
Originally I didnt bother with any Gate protection but found spikes were blowing them whenever the mains...
Hi All,
Has anyone used any of the Astec/Texas Instruments Point-of-Load Switching Converters sucessfully at all ???
I am currently evaluating both the Astec ATHk12 and Texas PTH12020 Modules (Almost Identical) which are 12V Input, 1 to 5.5V Output (adjustable), 18 Amps maximum output...
tda5051a ic
Does anyone know where I can buy the Philips TDA5051A Mains Signalling Modem IC in the UK at all (in quantities less than 10) ???
Cant seem to find anywhere that sells it !
Alternatively, how could I obtain samples of this IC, do you just email Philips and ask for them ??
Thanks in...
Hi All,
I am about to get hold of some old Siemens phones to have a play about with their Internal Modems via a PIC or AVR.
I've read that the 35 series have all(?) got internal modems but I am wondering what the difference is between the C35 S35 M35 versions, and the C35i S35i M35i...
Hi All,
I'm interested in trying to override the Rugby clock time transmission over a very small range (approx. 10 metres). Anyone know if this is possible at all, or has anyone actually experimented with this signal.
The actual digital part of the signal is no problem, but the RF/Antenna...
I*A*R for AVR Problem...
Hi all.
Am currently using I*A*R C compiler for AVR AT90S8515 and have a problem.
When I call one of my routines with for example the line:
lcd_print("This is a test message");
I am finding that the compiler is using up 1 byte of RAM for every character in the...
Hi all,
Just using the IAR C-Compiler for AVR for the first time, and I simply cannot figure out how to access a single bit of say PortA.
If I write for example PORTA=0x01 this is fine as its on the whole port, but if I write PA0=1 I keep getting an error "PA0 is undefined" even though I...
AT90S8515-8 at 3.3v ???
Hi all,
Atmel specify that there AT90S8515-8 AVR device will run as low as 4v, but my question is will it run at all from a 3.3v supply if run at at lower speed maybe ???
I know the AT90S8515-4 will run fine at 3.3v as it is specified as so, but I only have access...
Hi all.
I am presently trying to use Protel for home use. The problem I have though is that when I print out the PCB on the laser film, it dosent print out any holes, ie, DIL socket pads are just solid pads. I need the hole on the printout as this is used to guide the drill when doing it by...
That ERA-50 device from Mini-Circuits really does look the buisiness.
My only problem is that the minimum order they stipulate direct from themselves is a joke when you only require a few devices like myself.
Does anyone therefore know of a supplier for these devices in the UK that accept...
antenna tx radiometrix module
Anyone out there know any easy way of boosting the output of the Radiometrix 418Mhz TX2 modules at all, either through modification of the module or by additional circuitry. The standard output is only 1mW.
I am also after the circuit diagram for both the TX and...
