Putting a capacitor in oil is definitely worth it. In an 1891 patent Nikola Tesla mentions that glass and mica capacitors are inferior for high frequency use and its best to eliminate air near the plated by putting them in a container filled with oil.
The inductance of this type of homemade ROLLED capacitor can be greatly reduced by using electrodes that span the LENGTH of the Al plates. When rolled, the winding naturally produces self inductance since the current must flow along the cylinderical turns (a natural inductor). By using wide electrodes along the plate length, the current in the roll travels in straight, parallel paths from top to bottom, instead of AROUND the the rollrd foil. GREAT VIDEO!!!
I disagree with the claim that using oil would be beyond the simplicity that the caps are made for. In fact, they don't even have to be fully submerged. With a few tsp of mineral oil between the mylar sheets, you could vastly decrease the effect of corona discharge. Just seal up the ends of the caps with tape to keep leakage to a minimum. Great video though, I expected lower quality with the number of views but this should really have many many more views.
Good video, you are absolutely right wire legs are a pain. Flat legs are the way to go. I found some 0.1mm aluminum sheet that worked very good, but may need to be thicker for higher current. The corona along the edge of the foil is due to the ridged mylar leaving an air space at the end of the foil. Rolled on a pvc tube helps get it tighter. I've had good luck with 6mil poly sheeting.
Nice video. The copper to aluminum contact will oxidize in low moisture too. It might be better to use tinnes or nickeled copper wire stripped long enough to privide a large contact area. I actually twist the wires with the Al foil instead of simply taping them on it.
Anyone tried rabbit wire mesh? it would distribute charge axially and longitudinally on a roll. I think you have to get away from Mylar too on cost grounds. There must be some kind of digital twin modelling can be done here?
even with the corona discharge eventually breaking the capacitors they'd be so easily replacable that it's a non-issue if you take it into account with any designs using this capacitor. just make it replacable in any circuit and you'd be good to go.
I connected 20 Maxwell 2.7V super capacitors in series and I want to spark, but with each spark the voltage decreases a little from the capacities, the total charger of these 20 capacitors is 55V DC and when I connect them in parallel Their output voltage is 2.7 volts, how can I connect them to get 300 volts output?
You can’t. No configuration would yield that potential. I’d recommend you look into the fundamentals of series and parallel circuits before you mess with anything close to 300V.
I’ve talked with him about it and yeah, it sucks. Ever since I had stuff happen with authorities, both of us have abstained from working with energetic materials which might be part of his rationale.
@@alekescalante2010 Ha! Well I can’t complain, they made things go smooth and uneventful to say the least. But yeah, HV is fun and capacitors are the unregulated pulsed power equivalent of energetics.
@@DBXLabsI'd love to hear the story of what happened with the authorities if you're okay with sharing? A lot of us who have dabbled in the energetic world have wondered what it would be like if the feds came knocking... It's why I had to give it up as well

AGREED!

Nice work. And congrats on getting to 4K subs.
I love your videos and your varied interests you delve into.
Thanks!
I love getting high and watching repeating all you said, I feel like a mad scientist
7:08 I think submerging the capacitors in oil might cause issues for the adhesive on the copper tape as well.
6:28 This is beautiful
Aluminium foil between thick glass sheets also works like a charm

How does it eventually break them?
New video, awesome!
Have you tried using the copper tape to tape wire legs to the plate?
Nice,6:50 looks like upside down lightning bolts
Can you explode bridge wire detonators using these?
it posible make one with papel and mineral oil as dielectric for CW multiplier?
Are you working on a spark gap teslq coil by any chance ?
Yep. It’s been in the works for several years now but a video on it should be out by summer.
How does rolling the cap increase the plate surface area??
THANKS MUCH!
That brings more opposite polarity foil surfaces together that otherwise would have been far apart if it wasn't rolled.
can your hv generstor produces ozone n electrostatic dischsrge?
How u know 17.1V is the safe limit for ur ZVS driver to operate?

Flat with compression takes the inductance out
PTFE sheet. Man it's expensive!
Didn't you have a furozane and furoxaine video, where that at
That would be ReactiveChem. Great channel although those videos might now be on bitchute.
@@DBXLabs Ooooo i see , you sound kinda similar so i thought it was you
You can also coat the edges of you plates with corona dope
Would some oil help with insolation. Oh you mentioned it, sorry. This one's for the algorithm I guess.
The ultraviolet light from the bright white discharges are bad for your eyes ,dont watch it without uv filtering eyewear
U hear reactive chem not feeling making content anymore.

@@DBXLabs well high voltage is a fun alternative and its what I started on. That blows big brother got involved. Biggest organized crime of them all.
