Hi All,

I just wanted to mention a few important tips for MMC construction...


1.	Always make the strings individually selectable so you can get many
 different values of capacitance.

2.	Leave a small (~1/8")air space in between the caps in a string for
 air flow and to leave room if one fails.

3.	Be sure to leave a good distance (~3/4" or more) between the strings
 so if some are not used, that active strings will not arc to inactive strings.

4.	Put 1/2W 10Meg ohm (or some close value) resistors across each cap for
 safety and balancing.*

5.	Be sure the resister leads are actually wrapped around the cap leads
 so they will stay in place if the solder gets hot or the solder connection
 was not sound.*

6.	Remember that the whole cap is at very high voltage so it needs to be
 mounted away from metal and in a safe location.

7.	Perfboard, like DigiKey# V1011-ND, makes mounting the caps really easy.

8.	Do not connect the caps between strings together even though they are
 at the same potential.  This defeats the cap's self healing and value
 selection features.

9.	Even though the cap leads seem small, use heavy primary wiring and try
 to use brass or copper connections as with any Tesla cap.  Bringing the ends
 of each string to 1/4" brass bolts works well.

10.	Remember that even a small EMMC cap can be just as dangerous as many
 big oil filled caps...  The resistors go a very long way in making them safer
 but don't get careless.

11.	???  Others I have left out  ???

* People have gotten shocked by not doing these.
