I'm having a house built through a builder and i missed the Sparkies
when they were on site (i was told they were going to turn up on a
different day) and i was going to ask them to run a cable to the rear
family room for a 8.2kw cooling/9.1 kw heating spit-system air-con and

All,
To go along with another newsgroup entry, I, too, have been pulling out
some of my unused electronics-related books & magazines.  They are from
college and second-hand, so articles may be missing and they may be marked

Does anyone know the difference between the HGTP7N60C3D and HGTP7N60B3D
IGBTs.?
Thanks in advance.

Can Anyone tell me if the CA3162E is compatible with the 74HC4511
Im talking about the 4 data lines that go from chip to chip. ABCD - 0123
Normaly the CA3162 is used with the CA3161 but I was hoping to us the
74HC4511 instead as Ive got loads of them.

Hi People.
I am looking at a particular application. I want to build a currency
counter. The device will be based on optical technology. What I want
to do is, "look" at the side of the stack of banknotes and from there,

Going through my garage, I found a stash of old data books from the 80's and
90's: Burr Brown, TI,  National, and others. Considering most of these can
be gotten on CDs today, are these old paper books worth keeping, or should I
recycle them?

I'm sorry if this is the wrong area for this, but I'm new to this, so
please bare with me.
I'm looking for a circuit for a differential OP-Amp, that is caperbile
of working with a mic of 5 Ohm with an output level of 1.4-4 uv ?

I have a neighbor with one of those large 500W+ barn lights. I do a fair
amount of astronomy from my property and it can loom quite large at night.
He seems interested in helping but yet has not taken any steps about
reducing the light. I would happily pay for a motion detector. ...

Anyone have a circuit for a manually-adjustable, or even automatic regulator
to control a car alternator?
Application is deep-cycle battery charging using 3-5HP small petrol motor.
