I need to get a daily time update via a serial connection to a
microcontroller in my device.  This is for use in a commercial application,
so I need something reliable - but of course cost is a driving factor as
well.

Do batteries get heavier as they're charged?

Here are some photos of speakers I have acquired...

Can anyone tell me what the value of R152 is on a
Teac EU3216F television?
It's a relatively recent 76cm widescreen tv,
R152 is in the main power supply input section,

I'm trying to read the data from a protected chip (Samsung K9F5608U0B
YIB0)... Does anybody know what pins I would have to use to monitor the data
coming from this chip while its running? and also what software/hardware I
could use to capture the data?

Dear aus.electronics / aus.hi-fi,
How're things?
A long time ago I bought some floor-standing speakers made from Pioneer
drivers - 2 x 12" woofers, 4" mid, 3" cone tweeter and 1" tweeter.

Gday,
I know those things are expensive, but where can I find them in Australia.
Either single or multiple channels ?
Thanks

Has anyone modified this unit for sound triggering?
There are many photos on Flickr using a sound triggered module that is US$99
and I am wondering if the circuit in Silicon Chip or more recently
republished in a UK electronics magazine would be able to be modified simply

does anyone know where I can get a compiler that supports the PIC18F1320
microcontroller? I specifically need one that runs under linux, command
line would be great. C++ or assembler, im not to fussed. free would be
even better, moon on a stick would be fantastic.

I have an inverter that puts out a nice 120v square wave. The inverters that
put out a pure sine wave are expensive. Does anyone know where I can obtain
schematics to build a square to sine wave converter fo my inverter? Thanks
in advance.

Hi.  I've been tinkering with the odd electronics project for a few
years now, but I'm stumped on this one.  I've constructed this circuit:

timing belt... does anyone know if this could be possible?? I dont know
much about cars, but have concerns as the engine died in shop.  Thank
