@all   

All the new posts has a lot of new territery to catch up on, some of it is real good food to digest

However, I got troubles at my end, I seem not to be able to get a complete download of all the information people post, and I am not able to make PMs, even to myself.

Has anyone else noticed this today?

Also, on P546, 2 photos would not show up in their designated places on the screen, and only half of a circuit came through, I'm missing some info.

This makes it very difficult to follow the discussions.

Im on Dialup, 4Gig CPU, with 2Gig of RAM so this should be in the right ball park power wize.

I only noticed these hickups after the new forum web change cutover last week.

I am open for suggestions HELPPPPPP  lol.

Please see the attatched photos

When photographing TV or computer screens, bear in mind that the screen forms
in 1/25 th of a second. The shutter speed should be EXACTLY 1/25 or a multiple
of this (i.e. a longer exposure).

Next to impossible.

The next best thing is a tripod and a slow exposure of a second or so, hoping
that the camera can alter the iris accordingly.

since the cap has the ability to diliver more power faster i would imagine having the cap in parellel with the battery may be increasing the frequency. considering this is a self regulating curcuit IE when enough current has been built up it releases through the led its a self resetting thus it doesnt matter how much or how fast you can deliver current its allways going to max out at the same level here. but if its able to bring the curcuit to its activation point faster then perhaps its also increasing frequency?

hard for me to tell considering i dont have a scope. if someone feels up to it they could test this.

More base capacitor tests. This is with 5 turn base coil. Next post will be with 2 turn base coil.

More base capacitor tests. This is with 2 turn base coil. Last post was with 5 turn base coil. This circuit will light neon with only 3 mA.

This particular thread's been on fire since day one, so apologies if someone has already left the answer to my question....

Anyone know any links for advice on Earth Batteries?  And where can I buy supercaps from?  I'm in Russia at the mo, so i need a company willing to send them out here.

Thanks to everyone for their superb contributions to this great topic.  Pat on the back for the whole lot of us, and a special thanks to all the regulars...you know who you are
