  • 1:57 lol "and the pen - is are in there" lol

  • The Asian population, Hmong mostly, just 2 blocks west of me, Stockton Bl..commercial stuff..about 1-2 miles of nearly all Asian stores. I might find a variety of 'imported' electronic stuff like you found. I like to buy USA when I can, but the eectronics is mostly pacific rim (as they seem to call it) Copper wire? yes, the 'wire' gauge. and I see some of the steel wire with copper coating, a tad cheaper than solid copper, I see it in cheap stuff a lot. can't take much current though.

  • @dougspair

    I like to by American also but there are some things that aren't even available here. I marketed a small socket tester and I couldn't.'t fin an American company manufacturing piezo crystals.

  • Hey there you are again, ! I got some sort of message from NathanCinematography but couldn't figure out the youtube 'subscriber' deal. Where are you located? USA I kind of assume? Here in Sacramento, Calif..we have a variety of $ stores, near my home is RC Country (radio control) hobby shop, huge, still has the stuff we use for actually 'making' things.. Sacramento has a very large Asian population..I might find some interesting 'imported' electronic stuff. Just my 2 cents worth.

  • @dougspair

    I'm in Ohio. The radio control club I belong to is the CMAC Corsair Model Airplane Club. The F4U Corsair was manufactured in Akron as the story goes.

  • Very nice! ... If i may say, those 5 mm long LEDs are hard to fire up. I dont know why but i think you would get better light from a standard 9 millimeter long LED.

  • @iluzyon1

    Actually the diodes I'm using are salvaged along with the rest of the parts from solar garden lights. We have what is called a Dollar Tree store here and they are, naturally one dollar. For that price you get a nice thick glass solar cell, a Joule thief circuit and a battery. The diodes are very good for this type application because they will run pretty bright at 1.8 volts and probably only 3 ma. Thanks for your comment though.

  • Great Video --- As for the LENGTH of the 2.5 thou inch DIAMETER coil wire,... that would be given by:

    R(Ohms) = PL/A (measurements in meters) R=507 ohms, P = 1.7E-8 ohms (Copper constant) L = length in meters.

    So: R x A = PL or (RA)/ P = L

    And: WIRE Dia. inches, 2.5E-3 or thousands of an inch = 6.35E-5 meters dia.

    Then Cross Sectional Area: = (Pi d²)/4 = 3.16692E-09 meters

    Length = (507 x 3.16692E-09) / 1.7E-8 = 94.44878379 meters

    Length = 309.8713379 in Feet

    Steve. Ha, now I'm gonna have some fun. I prefer the SWAG method for figuring most things out. (Sophisticated Wild Ass Guess) Kidding. I'm impressed with your knowledge and have to admit I was never very good at such calculations. I use conversion tables to help me with most stuff. Being a master of reference is a useful tool. Buy the way this is interesting: The wire is extremely flexible and is steel with copper plating. How weird is that? 1 US dollar per roll.

  • @DadHav --- Thanks for more detail on the copper coated STEEL wire material,... this will then affect the Roh (P) value as the constant I gave was for normal copper wire at 9gr / cm³. ;-)

  • @DadHav --- Hi,... as for the SWAG use, we in Europe generally use SWG (Standard Wire Guage) --- and when winding motors ... if this helps ...SWG 46 = 0.0024 inches = 0.061mm or 0.0000061 meters.

  • The project is just too cute for me ;-). The Clock is good idea, IMHO.

    best regards!

  • @cest73

    Hey Old Pal. You must really have anything to do if you're hanging around here.

    Ha, Kidding of course. Good to see you're getting caught up and catching up on things.

    Take care.

    John

  • @DadHav ,

    Hi, contrary to Your assumption, i have quite lots "TODO"s so I miss on them hanging around here :^)

    ;)

    Take care.

  • I like this. Can you say comprehensive?

  • nice video, glad I subscribed :) cheers

  • Nice toaster cell. :) Love those solar bobbles, have a mini luckycat running for months. They sell all types on ebay but more expensive than the $1 store. Wish I had a store like that where I live..

  • @Wavefront101

    Actually the store is called Dollar Tree. They have a website but I haven't seen these on the site. Maybe if you ask.

    John

  • @DadHav Thanks for the info, I checked the website, and they do have it there. Just typed in "solar" in the search bar and it comes up. Amazing that they're only $1 each.

  • @Wavefront101

    Yes, I see that too. Maybe I'll check into getting some more. I'm gonna try a mini Mendocino motor with the Magnetic Ring suspension.

    Thanks.

    John

  • a blessing to see what you've done/replicated here...you are an invaluable resource to this movement...thank you for sharing, much love and aloha

  • @haggardhagi

    Thanks but Rusty at LidMotor was the inspiration for the fun little oscillator.

    John

  • @DadHav how modest of you, however your participation is what is truly appreciated here. The quality and clarity is also appreciated.

  • Hi John, how are you? Congratulations on the cool video, you like minimal tension, very interesting.

  • @Roda537

    I'm OK friend. Thanks. Yep, no matter what it involves it's minimal tension for me. Being heavily medicated helps too. He he.

    John

  • Great Video! I have one of my own crystal cell designs that still powering a LCD clock since October. Lidmotor was testing my stove top crystal cell with his penny oscillator, I don't know if its still running but it was interesting and fun project. You can check out my channel for some of my crystal cells, I'm now working on making a 5 foot tall crystal cell that I'll post a video of in a few days.

  • how many led can you put in parallel off the output? very cool video, thanks!

  • @ken25taylor

    I only plugged three in that I could fit. That might be about it for this little cell. Remember this isn't like the transformer circuits that you see people using to light up strings of Christmas tree lights.

    Thanks for watching Ken.
