Hello, I'm fairly new at electronics and wanted to see if I could build a little pummer. These little guys seem simple enough, charge during the day, light show at night. The nocturnal solar engine I'm trying to build is the simplified D1 ( http://www.solarbotics.net/library/circuits/se_noct_SIMD1SR.html ). I'm having some trouble so I tried to build the circuit excluding the capacitor and solar panel since I'm using a power supply to troubleshoot.
So I have the 2n3906 emitter connected to the positive of the power supply, its collector connected to the positive lead of the LED. The base of the 2n3906 is connected tot he collector of a 2n3904. The base connected to the collector of another 2n3904. The base of that 2n3904 is connected to the negative lead of the LED. The emitter of both 2n3904s are connected to ground.
For testing shouldn't the LED light up with a consistent voltage running through the circuit? Is it possible to use 3 volts for the power supply?
The circuit isn't very clear, the Q1, Q2, Q3 are not labeled. Can someone help clear up the circuit? Really want to build this little guy to be my companion.
I hope this was the right place to ask this, thanks for the help and sorry if it is in the wrong section.
