What type of caps are those? They look like the film/lytic things Ive seen on eBay. I've been wondering about those things.

As you can see in this pic:

those are PEH200YV447BM, a high quality, high lifespan, very low ESR and ESL electrolitic capacitors made by RIFA; you can found the datasheet here:

Ciao!

Liquid - macro shot. Looks like coffee or Cola.

Shit, that was dam close… But it is not so simple. You right in the fact that it is surface of liquid… In fact it is water in flat black jar which is exposed to mechanical vibrations (sinus wave approx 1KHz). At certain frequencies the higher harmonics creates very funny motifs and in case the light source is pointed from certain ankle these motifs can be photographed. I’m sending the original picture too…

2 Beefy stud diodes and 5 isotop diodes courtesy of rp181 (thanks!). These should stand up to a fair bit of power in my capacitor bank and will act to help block back-emf...

Also I have extracted some fluorescent dyes from glowsticks, and its a cool level of pretty. The vial on the far left is the hydrogen peroxide used to

I assumed coffee or cola because of an effect seen on the original. Your original posted image is larger than the unchopped one. When inversed again (back to the original colors) there "appears" to be an oily residue on the surface in the white reflections of the light source. Starbucks coffee has that "oily" look to it when black. The brown color also made me think coffee.

Coffee is still mostly water though... Do I win??? Lol...

@ aono
If you want a datasheet for the big ones, look at octopart.

Just added a Softale to my collections of HDs.

The Rocker C, wild bike and check out the 240 Dunlap on the back!

The Softale has no visible back shocks and the 96ci motor is rigid mounted, so the engine as to be perfectly balanced and the reason Softale’s are a bit more $.

Off to start waxing and ordering accessories. Life is good!


Cheers,
