Hi group.
With all the computers being scrapped, there must be literally
thousands of useless HDD's dumped every week in the UK alone.
So, things to do with them.

I'm designing an eprom programmer, but realised that since i have
access to lots of old flash eeproms, it would be better for me to
change the design to support eeproms.
Apart from the lack of 12.5V vpp, are there any other things i should

WTF is this?  A dictionary gone berserk?

.NO is Norway, and that ain't no FBI place.  Totally weird.
Bizarre.  I've never seen nothing like it.

NiMH batteries usually have a capacity larger than alkaline, but on 9V they
only have 170mAH compared to 500mAH for alkaline. Even some NiCd batteries have
larger capacities than NiMH batteries. Why?

dear reader,
For this moment I am implementing designs in CPLD's(xlinx
xc95-series). I was wondering what is the main difference between a
CPLD and a FPGA?

 I have a set of Shure earphones that act up at times.  I am quite sure
that the problem lies in the jack.  My question is there are 3 leads.  I
have bought a new jack, but I really do not know where to connect these.  I
tried a local TV repairman and he said he didn't know.  The ...

Can't find this power diode's specs on-line. Its a large stud-mount with
what looks like a porcelain cap on the anode which then has a
multi-bundled-strands thick (6mm total width) attachment wires with lug.
The stud is about 7mm wide.

Anyone have any spare wire wrapping tools which they would like to sell
for a nominal fee?
I did have one for a short time, until someone decided to borrow it &
never gave it back

I have two power supplies giving 110V AC as outputs - I want to connect the
two together in some way so that give 110V output. Can someone pls tell me
how this can be donbe safely. I am trying to create a backup system so if
one fails I can remove one supply and still not disrupt ...

We need to do an assignment for one of our subjects Power Electronics.
I have got no idea what to do this on. Examples are : Power inverters, DC
motor controls, and so on.
We are currently busy with power diodes, power transistors, SCR's UGBT's.

I Have Panasonic TV MODEL TC-14L3T but main transformator fail, did
anyone get information about this,
Transformator Number : 34K406A
TNX,

I am facing a wierd problem and already spend two days
trying to solve it. Please help.
My curcuit is based on PIC18F458 MCU. Something went
wrong when I started experimenting with driving a DC motor

Has anyone tried out/own the Oatley Electronics electric bike? (about
$300) I wouldn't mind buying one but cannot get to see what they are
like because of location.

I've download the trial version of P-Cad and am busy fiddeling with a few
schematics.
I've read thru some of the tutorials but am still clueless on how you find a
specific component in all of the livrary files they give you.

I felt a small shock when I touched the USB connector from the Canon Pixma
IP1500 printer and the grounded PC case at the same time.  It's not a 60hz
AC type of shock but is felt as very brief pulses of approximately 2-3
pulses per second when printer is in off mode.  These pulses ...
