make up a laboratory from scratch
 
Hi to everybody!

I need some of your important suggestion!
I'm willing to built in my house a little laboratory with all the necessaries things and instruments.

i would like to know,, according with yours diy's experience, what do you think is really needed.

Just skipping the obivious tools as screw drivers, tighter...and so on and so forth.....

i would like to hit the spat with an oscilloscope and other instruments that are really needed to be able to built your own project and stuff.

I would like specifically to know if it's possible to have an osilloscope and ... i don't know,....for instance something that measures the tdh+N (....with an output module to plug to the computer with a software...) and if those modules would be as effective as a dedicated oscilloscope.


I aware for your responces.


Thanks in advance.


Best regards,
Stefano.

My suggestion is that the first thing to have is a high quality and complete multimeter. I own one Metrix X56 (to sell) and two Metrix X57. I don't even use all the functions but some are very nice for audio work : peak, RMS, dB, Hz, Ohm, Farad.

yes i do agree!

How much for one of those?


I have seen on pass lab's section a similar post....about the distortion analyzer.
I didn't really understand if an external module for the coputer would be consider as effective or not.
I just fond UPV analyzer that looks great!

Does anybody have other ideas?

Hello all,

Have a look here : http://bas.elitesecurity.org/mojiprojekti1.html
This site was made by one of our member Dr. Boraomega. You can find nice schematics as function generator, THDmeter, frequency counter or something like that.

Regards.

how about a circuit simulator
 
you might wana get a circuit simulator

circuit maker
multisim
orcad
superspice

they real help out alot
and are high accurate save alot time
student edition are good

when build circuit get a bread board and junction wires

do you know how to make circuit board
thier alot ways go about it

if you look for a muilti meter true rms

A Variac is mondo important and i have a nice Fluke 189 Multimeter. When looking for RMS readings, make sure they state the frequency range the meter is accurate for. most meters are only accurate for 60 or 400hz rms and not for higher frequencies.

A bench power supply that is adjustable and regulated.

definitly a good scope. and a signal generator, function generator if you can.


This is where i would start for a lab.

The function generator and the distometer of Maxs's link seem to be very similar to those published by Ian Hickman in Electronics World.

My most useful instruments are lab power supplies (home made, two 0 to 30 V, 1 to 3A, and two +/- 15 V) a little function generator (for most work, very low distorsion is not needed) and a scope.

Look around for an old FETMETER , I bought 2 for about $10 each. Unlike digital meters they are good for measuring AC volts up to 100Khz, (digital meters give inaccurate AC volt measurements above approx 5Khz)

Also
signal generator
Dummy loads
An old speaker for testing that you dont mind blowing(just in case)
A descent bench light (often overlooked)
lots of cables/leads for meters & scopes
cables with alligator clips at the ends
An old scope is allways nice to have.
A handheld (digital) scope is great, I use it for the AC Voltmeter & freq meter, the actual scope display is too low res to be any use for audio.

If you are building a space to work in, can you add a fan to vent air outside when necessary? :D

Lots of outlets to plug your equipment into!

I've got a whole bench full of stuff,and only one power-strip to use.. 6 outlets just isn't enough,I need 6 more! Swapping plugs around,and trying to figure out which one is for the function generator is a hassle,in the middle of a project.

Then you realise you just unplugged your soldering station,and now have to wait for it to warm up again. :xeye:
