I counted the squares on the cutting mat and guessed the dimensions of the tinfoil strips, it's roughly 3 x 25 cm, so an area of 75 cm squared. Didn't expected 2 nF of capacitance at all, quite surprised! Thanks for the video, really informative: I appreciated that you showed both the entire building process and you took the time to make all sorts of measurement, the most interesting to me being capacity since I would like to assemble my own for fun and exploration and I wanted a ballpark figure to know what I should expect out of it
We made Leyden Jars when I was a kid in science class. I did this years ago but just on my own, no plans. I used all sorts of insulators and conductors, sadly back in the 60s I had no way to test them other than an old Heathkit VTVM to see if low voltage A.C. would pass through. The one you made with the double stick tape and shrink wrap was a thousand times better than mine were. An interesting video especially with all the test gear. BTW I received my pcb to build the capacitor tester, now to get the parts. Regards, Tom
I have never tried a Leyden jar. I would love to make that sling that you hang a kid in and load him up with static electricity and watch the gold leaf fly around but I doubt that would be allowed these days. Have fun with the capacitor tester kit an be sure to let us all know how it comes out.
All I remember about the Leyden jar was we used our moms Mason jars and only managed to spread a V shaped piece of foil. Yes I'll let you know how I do with the cap tester. I'm trying to assemble all the parts. Do you know if Mouser sells to individuals or wholesale? The parts list has Mouser part numbers, it may be easier to order from them directly.
Check the videos on youtube from CE Manufacturing showing how they make capacitors, and their videos include the process of forming the capacitors after assembly. They set a high voltage variable power supply to the rated DC current value of the capacitor and ramp it up at the current limit, topping out slightly above the intended operating voltage. (540 volts for a 525 volt rated capacitor) In their case, the current setting is about 1.3 A.
Soak the paper in an electrolyte to increase the capacitance. About 3 or 4 teaspoons of baking soda dissolved in a cup of distilled water. Then it will be much more useful. You have to figure out some sort of can to put it into so the liquid doesn't just leak out or dry out.

Cool. Have fun an keep us informed .
and a BIG Plus ,Sir, to increasing knowledge of electronics!
Thank you. I have some ideas that will make it better.
thank you bucimara.

@@thomasheckhaus205 yes mouser sells retail 1 piece at a time. That is the easiest way.
GREAT, thanks.
@@thomasheckhaus205 your welcome. If you have any problems finding the parts give me a holler at aervblog@gmail.com
Thanks so much,very informative...
Glad it was helpful!

Excelente instrumental 👌
Gracias por su aporte, saludos desde Argentina 🇦🇷👋
Thanks for watching. I have been looking into how to make a better cap. It needs some electrolyte also.
Check the videos on youtube from CE Manufacturing showing how they make capacitors, and their videos include the process of forming the capacitors after assembly. They set a high voltage variable power supply to the rated DC current value of the capacitor and ramp it up at the current limit, topping out slightly above the intended operating voltage. (540 volts for a 525 volt rated capacitor) In their case, the current setting is about 1.3 A.
Thanks. I will check it out.
How to increase the capacitance and how to charge it?
Soak the paper in an electrolyte to increase the capacitance. About 3 or 4 teaspoons of baking soda dissolved in a cup of distilled water. Then it will be much more useful. You have to figure out some sort of can to put it into so the liquid doesn't just leak out or dry out.
@@AERVBlog So soak the paper before u start gluing foil?(ty)
@@AERVBlog Can i let it dry
@@TobyCharlesThompson no. It has ro stay wet. That is what happens to old caps. They dry out and reduce in capacitance, usually due to heat.
@@AERVBlog oh ok
would be nice with a bit of commentary
What do you mean?
