joule thief 01 PUBLIC

Joule Thief circuit. CL have changed something in the simulator because this used to run with the sim set up as. Now, it does not show the exponential rise of V1 and does not start oscillating unless...

LDR switched LED 01 PUBLIC

Simple light operated switch turns LED on as light level reduces and off as light level increases. No filtering to smooth out light fluctuations due to passing shadows. Based on 2 transistor Schmitt...

LED multi string linear constant current sink 01 PUBLIC

DC Sweep doesn't simulate properly in CL for all values of R7. Time Domain simulation shows erroneous current spike at startup. See below.

LED multi string linear constant current sink 02 PUBLIC

An attempt to get the time domain sim of: LED multi string linear constant current sink 01 to work properly. It doesn't. Time Domain simulation still shows erroneous current spikes at startup.
