Correction on the purposed PV LED circuit.

Yes, I made a mistake on the circuit I popped out of my head.

+---------+---+----------+---------+ | | | + + | 3V bat--- | | - - | 10K | ^ Vf 50 >| ___ | + Sch PNP |- -|___|-+ === | /| | GND | | | | | | +-------+----------+ .-. | | | | | | | | | | 47 | + | '-' | | | | | - | | | --- 3 Volt PV | V -> | | | - | | | | GND | | | | === | + GND | +------------------+

And don't ask me how to invert the PNP around in that program. I gave up trying..

I forgot in the last circuit about the emitter lifting .

Yes, JF, I made a mistake.. But In any case this will work with a

3 Volt PV.. and a 1N5817 type Schotty will work for this. How ever, since it's obvious that a single PV isn't going to do shit to aid in charging or supplying power for a solar device like this, it's only assume that a multi-cell unit would be in use.

The original posting was to simply use a PR, (Photo Resistor) to switch. I am offering both here with one device.

"Mirror" perhaps? (second button from the top on the right side of the schematic area)

Petrus beat you to the punch by noting that the PV array could be used
as the light/dark sensor, consequently eliminating the need for the
LDR.

Why is your scheme better?

It can charge the battery?

Jesus. I don't know what Petrus did, all you did was attempt to pull him away from anything other than your idea. He only wanted a simple solution. I offered one that can also help top off the battery at the same time. Like me, I offered, not shoved it down his throat.

what a putz.
