** CSLR Challenge 114 - Centred Composition

Go to last post
Two really fun shots, jgb! This challenge is different from the mini-challenges in that you need to post your shots in the gallery, here:
http://www.pbase.com/cslr_challenge/cslr114_centred_composition

To do that you need to email to this address to get the password:
passes[at]imageattic.net. Please replace [at} with an @

All the instructions and rules are here: http://www.pbase.com/cslr_challenge/faq

You will need to be quick as this challenge ends tonight and the images need to be in the gallery a couple of hours before the voting starts or the voting booth may not see them.

Please do make the effort to enter them though, it's a fun and friendly group and you will learn a lot! Welcome! Sharon

Re-reading that post, I see that it was not very clear at all.

....to post them in the Galleries and I'll do it for you.

I meant to suggest this last night but forgot.

I'm not sure that you can get the password within the next 4 hours.

Either way works for me.

Nice shots though.....interesting.

Best Wishes, Traveller
 
....everything's tough.

I need to stop being a winer....lol....and get back to work.

There have been some serious upheavals at work of late making me question my willingness to remain with this company. I guess I've just been feeling sorry for myself and being a whiner too :)

Onward and upward!!!

Where does the time keep flying? I added an entry to Eligible, but I'm really not satisfied with it. I'm afraid I won't have time to do it properly before the deadline. So I decided to just upload what I had.

I still use an analog TV (or actually, I use analog again, since I had cable for a while but cut them off when they raised rates and discontinued my favorite channels at the same time).

Anyway, for best reception, I plug the cable into a potato. What you see pictured is the result when there is no analog signal to pick up. That is what will happen when analog signals are discontinued next year.

I like some of the symbolism in the photo, but I also recognize that most people will probably not get it. It's a "for me" picture.

Or is that the result of having one connected to the cable feed as it's growing? I always new that stuff would cause mutations! Reminds me of Zappa's "I'm the Slime" in a way :)

It's as if you may be showing what could happen to any of us who are exposed to the signals emanating from that cable....

Good! That was part of what I was trying to show. I may have to do some more experimentation, but I think potatoes respond similarly if simply put in a cool place for several months. I am curious, though, how much of an effect the electronics have, though. Obviously there is some potential for an effect or else the potato would not work well as an antenna (it works MUCH more effectively than the amplified antenna I got at the electronics store).

There's still some time left to get the shots posted into the appropriate gallery.

Thanks for participating!

And here I thought I was being original! Here's how I came up with the idea. I got frustrated that my antenna wouldn't get me the results I wanted, seemingly no matter where I pointed the arials. So I disconnected the cable and shorted it out with my finger, a trick the cable guy told me about. That gave an instant picture but only as long as I was shorting the cable with my finger.

The original idea was to discharge any static electricity that had built up. But then it turned into using myself as an antenna. Soon I discovered that shorting out the cable wasn't required. All I needed to do was to touch the inside wire.

Well, watching TV while touching the wire gets old pretty fast, so I decided to find an alternative for myself (the wire touching role, not the TV watching role). That's when I decided on the potato. It worked perfectly.

a dry, non-conductive skin to prevent the center conductor of the "F"
connector from being shorted to the shield. So a spud should do
nicely!

From my shorting experiments, I would say the connection between inner wire and outer shield is unimportant.

I guess I should try it some time.

I would have thought that shorting the shield to the inner conductor would kill any signal. Perhaps it has to do with the impedance of the "short".

But, reading the chain of experimentation that lead to the potato being used, I see that the potato is actually a substitute for the TV viewer.

So when we use this technique, we're the couch potatos and the other one is the antenna potato. Or should the antenna potato also occupy a couch while in use? And if so, does this improve reception compared to other potato locations?

Clearly, more experimentation is going to be required!

...all over the place!....lol

But, you're down to 22 minutes I believe.

Give me the dates taken and I'll pop them in.

... about the terminating 'resistance' that the finger or the potato presents to the cable. I acts as a terminating resistance of somewhere around 10K to 50K ohms ( ...not taking into account capacitive and inductive effects ...) which then allows the shield to become part of the transmission line rather than act as a simple 'shield'.

i.e. the cable becomes a 'long wire antenna' which in itself is quite an effective 'multi-wavelength' antenna, presenting some gain over a simple dipole arrangement..

But... that's just my view on the subject... I have played with antenna feed systems for years and the more one reads about the phenomena... the more one realises that it is rather a magical and obscure science that is very much more complex than it seems.

The more I read, the more I realise how little I know about it!

Anyway, I find your experimentation really interesting Victor you seem always to provide an interesting and different take on the theme.

Great stuff, thanks for posting this.

Regards Bob (VK3WS)
