The LM337 IC is designed to be a constant current regulator. The advantage of using it vs a LM7805 is that one can run at much lower currents with the LM337. In my generator, I use an LM337 with a 330 ohm resistor, and that regulates the current to be 200 microamps (0.2 mA). Running this for 24 hours makes very high quality CS with tiny sized particles (barely perceptable Tyndall effect) along with the ions.
LM337 regulators are available from a number of electronic supply houses - I get mine from Jameco. They are not carried by Radio Shack. --Steve Y. ----- Original Message ----- From: "Marshall Dudley" <[email protected]> To: <[email protected]> Sent: Thursday, November 10, 2005 8:51 AM Subject: Re: CS>Ole Bob's Constant Current CS Generator > What current?
