I have the following problem, I need to convert the linear range from
0 to 5 Volts in a measure of weight (from 0 to 9999 tons) displayed in
a 4 -1/2 digit 7 segments) display and I was wondering if a Voltmeter
rightly tuned could do at job.

This is my first post to this group so i hope you will bear with me..
I recently purchased a Tek 7704A scope(embarrasingly cheap)...The only
problem was that it was not working..Having used tek scopes many many
years ago I decided to attempt the repair..Found a shorted cap in the

I  am very interested to know how a cordless portable soldering iron
works with just three AA batteries.
What is the diameter, length,and resistance of the heating coil?

Anyone have a manual for the VU Data 5110 Semiconductor test set?

Anyone know where I can download a manual for this?
Thanks.

Dear Potential Ham Radio Enthusiast,
Recently the international body that regulates the radio spectrum removed the
requirement for knowing morse code to get a 1.8-30 MHz amateur radio license.
If you are interested in ham radio then I urge you to contact the FCC

I have a Yokogawa DL1520 DSO with GPIB interface.
I've got this project where we have to store the waveform captured by
the DL1520 as a file on the HDD of a PC which can be used by other

I'm starting to learn electrical
engineering (from "The Art of Electronics") and I want to get a
'scope. I'm considering a Tektronix 465 or 475 from ebay. Is it worth
considering? I want a scope that's as versatile as possible, but I don't

does anybody know where one can get a charger for Li-Ion Cells? Not for
entire batteries.There are so many cool gadgets for NiMH and NiCd, but
there's nothing for Li-Ion.
Any suggestions?

where would I find something like this? I know National makes current
sensors, but where do I find a hi-precision voltage sensor?
Any suggestions greatly appreciated.
Ole.

Looking for a service "product support" manual for this 1990 vintage
spec analyzer.  Haven't been able to find one at the "usual sources".
Would like to borrow, copy and return.

I just inherited a Tektronix 533 oscilloscope and it's cart. I don't
