It seems that things on here aree getting a bit....wellll.... limited. Ok, a posting on here for a flashing dog collar (or on one of the many newsgroups)
...while silly, got me athinkin'. anyone want to try a design challenge for the worlds longest LED flasher circuit?
Simple....easy cheap parts is the main reason why I picked this subject. We could actually post pics of our circuits working...and occasionally check back to see whos lasted longer. Yah...the worlds greatest Hi-Definition TV design would be more challenging...but even guys without a lot of design and practical experience could get in on this one.
NO DEDICATED LED FLASHERS ON A CHIP like the long discontinued 380whateverthehellitscalled chip, and no SOLAR CELLS for recharging. Maybe we could even say that it has to be able to run off of a single AAA cell... or 1, 3ag button cell...but im looking for more input on that detail from y'all.
Maybe a challenge on the longest to keep a ultrabright white led continually lit from a specific number of batteries???.
Anyone else have any ideas on a circuit that could be used in a design challenge that would use junkbox parts...let us all know!!
Ill actually stick my neck out and say that Ill send a trophy to the winner.
anyone up fer a good ol-fashioned simple design challenge?

Well Robert...there are quite a few beginners that read this Board. Maybe you could enlighten us all, and post a design that would remove the gigantic Pickle from YOUR ASS!...and then design another piece of equipment that would remove the Pickle from the Pickles ass. This would seem to be a fairly important thing to design....HURRY! TIME IS OF THE ESSENCE!Robert Reed wrote:Sorry, but I regretfully have to decline your offer -- I am too busy designing useful and sensible circuits.

Hey...I just attempted to get some sort of interesting thread going with the less"seasoned" members of tjhe group. Go back and re-read your posting and see if you dont sound just a bit POMPOUS in your reply.... jackass.Oh...and GOOD sarcasm doesnt just repeat what the person originally said.Robert Reed wrote:Bigkim , Now that sounds like a useful and sensible design, but before I get started, there are certains parameters I need to know such as - HOW BIG IS THE PICKLE NOW RESIDING IN YOUR ASS! Since you mentioned time is of the essence, I am assuming you are in quite a bit of pain.
Besides...why are you even responding????...arnt you far too busy with your IMPORTANT design work. In the time it took to re-post...a IMPORTANT designer such as yourselfcould have designed a nuclear powered flasher.

I could do a month with a LED that has a built-in flasher....I was thinking more along the lines of months, if not years.....Chris Smith wrote:My last simple one ran for over two weeks straight off two AA Nicads and a 555.
And I didn’t even try to save on energy.
Slow down the pulse, drop the voltage,... and a month would be nothing.

Hi there,
I did a test once to see how long i could get out of a High Brightness
Green LED (because i had that one laying around) but it could have
been a while LED too.
I connected it to a 9v battery via resistor and it ran for 39 days,
until which time it was still lit up but i considered it too dim to use
for anything useful.
The 9v battery wasnt even new, it was used ha ha.

LEDs vs Bulbs, LEDs are winning.

I was an amateur back then, and my cells were used pulls from silicon valley.
All 5000 of them.
All I needed from the experiment was the battery life, not the flashing led experiment.
Based on the discharge of the 555 and circuit, I got well past the predicted 40 hours by quite a huge factor of 8 times.

How about a pickle powered LED flasher using dissimilar metal electrodes shoved up the pickle's a$$? You could make as many cells in series as would be appropriate by slicing up the pickle into separate cells.dyarker wrote:wrong forum, pickle picking would be "Robotics"
lighten up guys
er, a pickle powered photonic puppy pulser...as it were. Of course, sour pickles might make the puppy pucker!
Lately I've been spending my spare inventive energy developing a design for an automatic water hose powered playground swing. But that's mechanical design and this is an electronics oriented message base.
