I am looking at USB interfaced PC O-scopes and was wondering if anyone has
experience with either PICO or Link in a 100MHz dual scope configuration.
I have access to plenty of equipment at work, so this is to fill my home
and/or hobby wish list.

Has anyone succeeded in creating a thermometer using the LM355z
temperature sensor?   I am keen to use it rather than the popular
ds18b20 because of cost and the calibration facilities it provides.   I
just have not seen any circuit diagrams around.

Anyone know where I can find a cheap small color camera (stills or video) to
interface w/a microcontroller.

Does anyone have a circuit for an interface suitable to connect an
Australian telephone socket to a pc soundcard?
I want to try the VRS software on http://www.nch.com.au/vrs/index.html

I am in need of a few ZIF sockets to house 8-pin surface mounted chips
(serial EEPROMs).
Any ideas where I can buy those in Australia?

I ran a amplifier via  a fuse on the speaker and while the audio was loud it
wasn't as loud as it should be, I took the fuse out (soldered over it) and

At about 6:50 this morning whilst having breakfast I noticed a burst of
interferance on the radio (FM). It went on for about 20 secs - enough

minutes later upstairs in the bathroom I noticed my watch had stopped

I have a M27C512 chip that I need to copy, however, it seems as though
there is a copy protection on the chip.  Is there an IC programmer
that lets you make a 1 to 1 copy of a protect IC chip.
Every time I try to do a read from the chip, all it reads is FF FF FF.

electronics! Any help would be much appreciated.
