Hi Dats, I think the street lamps look very nice.  :thumbsup: Are they scratch built or store bought? If store bought what company makes them?

Cheers,
Rich S.

How are you doing, Rich?
Anything new on the Long Valley Industrial railroad?

About the street lights, my brother in law bought through eBay. And he gave me 5 of them. They are really cheap....I thank.

I'm posting this from my cellphone. Hopefully the link works.

Please keep me updated on the Long Valley, Rich!!

Hi Dats

I think I can see your problem with the lights. Solving these problems is what makes modelling fun doesn't it?

I was thinking that a solution might be to drill a large hole in your baseboard from underneath using a hole saw of 1"-2" diameter say. At least then it would be easy to poke your skewers through.

I've seen lamp poles similar to yours on EBay and wondered what they were like. Yours look pretty good and they are quite cheap so I'll need to give them a go as well.

Hi Dats, Thank you for the info on the lights, I may have to add some to Long Valley. The Long Valley Industrial Railroad has been selected to help break in a very special locomotive. The full public announcement with photos will follow later this week.

Rich S.

Hi Webbo

Thank you for the idea.
I'm contemplating with spacing of the lamps now.
In other words I'm not doing anything!
I like the generic looking of the lamps.
It doesn't disturb scenery much. (less obvious.)
And it made out of metal tubing.. I think.
I tested if it works and was fine. Let's see if it still works after my wiring work!

Hi Rich!

That sounds exciting!!
A very special engine?
I can't even guess what it is.
I'm definitely looking forward to seeing that!!!

I'll be back when I poke three more holes on my extension.
The Bamboo skewer tool is working well. Amazing!

Dats, Oh no, what did you do to your wife to make her so mad. Maybe you need to spend some more time in your Closet to let her cool down  :laugh:

He put three more holes in his extension!  :o

I have to say Dats, the layout is coming along nicely.  :thumbsup:

Hello

:'(     :veryangry:  This was my dramatization of "when I forgot our anniversary".
Have I ever forgotten our wedding anniversaries?............yes.

Ok, I made three more holes.
And street lights are up.




The poking machine at work!!



Now wiring.
I need a lot of help on this. My electronics knowledge is extremely limited.
Let me tell you what I know about electronics so far.
Thunder lightning is some kind of electric......the end.

Do you think that I can still light those LED up?

I'd like to connect those LED in the most simplest way possible.
And I'd like use AAA batteries.
Also I'd like to connect them is "series" wiring.
But before that, this is "series wiring" right?


My brother in law said the lights are 3v maximum and 3v is too bright.(I'd like to light them up dimly. I think that's more realistic.)
And AAA said 1.5v.
If I connect them in series, do they light up with one AAA battery?
It came with resistors too.

Can I connect this resistor on "+" before LED's?
 :help:

if you go series you'll need the number of leds x 3   volts to get them to work at full tilt,if you go parallel you'll only need  3 volts to get  them at full .personally id go for parallel,use 2 AAA batteries and try that 620 ohm resistor to see how they look,if there still to bright id add another resistor in series ,if to dim  2 try resistors in parallel

Hi Dats

You've got to be a bit careful in wiring up LEDs to make sure you don't blow
them up. Here is a wiring diagram that I think should work:



Power is supplied by 3 batteries wired in series i.e. + terminal to - terminal in a row. I suspect you'll need 3 batteries as LEDs typically need a starting voltage of around 3V depending on their colour. Three batteries will give you something like 4.5V which should be plenty. Your resistor which is essential needs to be wired in series as shown. No current limiting resistor resistor means high current through the LEDs = shine briefly for a fraction of a second followed by a puff of smoke. The LEDs are all wired in parallel as shown with the LED anode (red wire probably) connected to the + end of the battery. If  the LEDs are wired the other way round they won't work, but nothing horroble should happen.

If the lights turn out to be too bright, then you can add more resistors in series. If too dim, then you could reduce the resistance, but I wouldn't go below 200 ohms to start with.

If you have a 12V power supply on your power pack, you could use that to power your lights.

Am looking forward to some night time shots in the Closet with the lamps working.

Hi themadhippy and Webbo

You guys are geniuses!!
Thank you very much for your help!
Both recommend parallel wiring so parallel it is!!
One unimportant question: why do you need to connect a resistor on negative? You know, after the electric already went through those LEDs?

I'm planning to scavenge a battery box from my daughter's old junk toy which she doesn't even remember that she had one.
Let me dive into her junk toy pile now.
I'll get back to you after my scavenge hunt.  :dunce:

Hi Dats

The resistor could go on the other (left) side of the circuit just as easily (i.e. connected to the positive end of the battery). But, you most certainly need the resistor on one side of the circuit or the other unless you would like to buy some replacement lamps right away.

Thank you once again for your help, Webbo!!

You mentioned replacement.
Eh.... That would be...eh..impossible.
When I was using my poking machine, I enjoyed it so much that I made those holes a little bit too wide.
So, the lamps were wobbling and I super glued them on the sidewalk..... :-[
What was I thinking?
I was thinking about only the poking actions. Not for unforeseen future events.  :-[
Well, dumb happens.(quite often.) At least I was enjoying the super poking action though.

As you know I don't know anything about electronics so I decided to wire exactly as the drawing. (Thank you again, Webbo and themadhippy.)
I should've paid attention on science classes 40 years ago.
(My favorite topics were lunch time and recess.)

I haven't found a battery box yet and even if I find one, how do I know it's wired in series or parallel?  :hmmm:

By the way Webbo, can I get away with only two AA or AAA batteries?

The Closet Branch-Dumb happens enjoyably™

Dats

Hi Dats, since AA or AAA batteries are both rated at 1.5 volts, placing two in series will give you 3.0 volts. If you place those two batteries in parallel you'll only have 1.5 volts but you'll double the current output from the batteries, which could over load the LED, so be sure to place them in series. I believe you said the LED lights work are rated for 3.0 volts? So two batteries should light the lights. I believe Webbo mentioned if you use 3 batteries, you'll need the resistor to limit the voltage to 3.0 volts so you don't let the magic smoke out of the LED's  :laugh: But by using 3 batteries you're giving yourself a little extra as a reserve.

As for the poking action, yes I did get a good chuckle from your explanation of events  :smiley-laughing:

 

Cheers,
Rich S.

Hi Dats

LEDs weren't even invented when I was in school so paying attention wouldn't have helped. LEDs are a bit different from devices such as resistors. They need a minimum voltage (the forward voltage Vf) to pass current in the forward direction and being diodes won't pass current in the other direction. According to Mr. Google "Standard red, orange, yellow and yellow-green LEDs have a Vf of about 1.8 V, while pure-green, blue, white, and UV LEDs have a Vf of about 3.3 V". In other words, if your lamps are red then 2 AAAs providing 3V will be enough to power them, but if they are white, you will need 3 AAAs (4.5V). The resistor is there to stop too much current passing through the LED.

You could always try the experimental approach on one of your lamps to see if 3V is enough, but make sure you have that resistor in the circuit.

The battery box could be wired in parallel or in series. If the batteries go in so the + on one is next to the - on its neighbour, then I would guess that you are looking at a battery box wired in series. If you have a voltmeter you can stick batteries into it and look at the voltage of the output.

I would think that supergluing the oversize holes is lots of fun as well so you are a double winner (the delights of poking and gluing).
