I recently acquired a few interesting large capacitors.
5 that are 7,900 uf 350WVDC
2 that are 490,000 uf 35 WVDC (max surge 40V)
I am hoping they are not blown, I think they were replaced because of an upgrade in which the replacements have to be larger so these were discarded.
No need for warnings... these are seriously dangerous toys when charged.
to give a nice feel for how different.
a disposable camera at max is around 160uf or so (350volts)
A commercial flash unit for a DSLR can be 10 times as much so that you can take many pictures before waiting for a charge. 1600uf
you would need around 3000 disposable camera capacitors to match the uf of just one of the large caps... (but voltages are not equal).
discharge that with a screwdriver and it will not be pleasant...
I wonder what great hobby project one can use one or more of them for.
and just to limit the list to something a bit more reasonable
(as I live in an apartment)
no sasquatch stunners
no rail guns
no tesla coils
no emp pulse
no Jacobs ladder (already done it)
no shrinking coins...
ok.. I know... took out all the best fun ones...
but really, how suitable are those for an apartment?
I also have a collection of some motorized micrometers
so what I thought of was using a 1amp laser, and pulse it at much higher power, and perhaps make a micro CNC machine.
[my day job is an applications developer for research computing so the software and such is not the hard part for me, the hardware and such is more so]
this CNC would not be able to work on anything larger than a postage stamp given the micrometer travel distance.
how long could one run led lights off of something like that?
use the cap as a battery with a high cycle life for some solar cells I have laying around?
I have some weird spare parts that are always looking for a project.
a nice collection of small vacuum arc gaps...
well, be interesting to hear what comes up
if ideas are interesting I may take a picture of the strangest parts for doing things and then see what comes up... but no promises, life has been very busy lately..
