The same cannot be said for DSOs like the Rigol.

Learning to use one is quite tedious and you can never really trust
what you are seeing

Whilst an analogue 'scope

** That is definitely a wild overstatement.

Something TW is world famous for.


- the fact that sampling is at a *different rate*
with each step of the horizontal means the usable bandwidth is
constantly changing and there are strange artifacts from aliasing
too.

**That much is true. Vertical resolution seems to be still quite poor on
even high end DSOs. Analogue 'scopes rule here.


*** Yes, there is sometimes hundreds of times more information in a good scope trace than a grainy DSO screen - which always looks like noise to me.



What you see in never in real time, there is always a delay and even
when the input signal stops, the DSO continues to display it for over
a second.

**I just checked my 1054Z. I don't have the time or the facilities to
measure it, but I'd estimate way less than 100msec for both. The delay
is not noticeable.


** But it is long enough to completely miss contact noise when you operate a signal switch while rotating a good pot produces visible noise all the time.

I find the DS1025E near unusable for trouble shooting work.


**Which is exactly why I dumped mine for the 1054Z. MUCH better 'scope.
Picking up noisy pots and switches is a doddle.

Doesn't taking the starter out remove the ballast from the circuit?

With the ones I have you put a short in place of the starter, so no.

if you do that then you will get almost the whole of your mains supply
voltage across your ballast... hear a big bang on energisation... your
circuit
protection operating... and you will probably be the owner of an
ex-ballast.


Nope. That’s the way plenty of LED tube replacements do it.

i would suggest it's just left open circuit.... the ballast is basically
there to provide
the inductive back emf high voltage kick to get the gas to ionise inside
the tube...


Its actually there to provide a choke to limit the current thru the tube
once it fires.

Quote:
once it's struck the starter stays open and the ballast remains in the

(most of the voltage falls across the lamp) but doesn't do much except to
stabilise fluctuations in the operating point of the circuit


Thanks for that completely superfluous proof that you
have never had a fucking clue about anything at all, ever.

breaker

the lamp itself.

i would also suggest that fluoros are pretty energy efficient and my gut
feeling (based on experience) is that the cost saving wouldn't be worth
it.
i'd have to do the calcs to be sure of that tho. a significant factor is
the number
of times you turn them on in a day... as on start up they consume the most
energy...

Tell him if he doesn't want it, he can give it back to you,

IME, they have to decide what interests them.

Maths, logic problems are really easy stuff and may not indicate the
ability to do deeper work. books of puzzles might be all that they are
interested in.

Basically, they are only 5-6, just liable to be fanatical/absorbed if it
interests them.

It was started here, to our shame, but it got picked up in a number of
other countries.

Showing support by turning off efficient lighting, and burning
inefficient CO2 emitting candles instead, is a common theme.

Earth hour is, above all, a demonstration of ignorance.

**Well, not really. It was designed to make people aware of the problems
this planet faces and that we ALL need to work together to make a
difference. Certainly, turning off pool pumps (or filling in a pool,
like I did), or air conditioners will make several orders of magnitude
more impact on the environment than turning off some LED lighting, but
lighting is easy to see.

**The average Chinese citizen emits less than 25% of the CO2 than an
Aussie does. The average Indian citizen emits less than 10% of the
average Aussie.

Which nations caused the vast bulk of the human induced CO2 in the
atmosphere today?

Hint: It was not China nor India.

A: It was us in the West. It is up to us to demonstrate a willingness to
reduce CO2 emissions. To do otherwise, would be hypocritical.
