An automatic dark sensor can be made using a PNP transistor(BC557).
As the ambient light falling on LDR decreases, the LED glows. The sensitivity of the circuit can be adjusted using the variable resistor VR1.
If this circuit does not work with 10K, use 100K.

Your website looks very informative, but why dont you incorporate the Joule Thief into your circuits? Any particular reason?
There is one problem in this circuit during the ligth transtion it gives flickring ( i am operating a relay). Please suggets if someone has done something to remove this.

You will find only some variant of Brew Central established on cups this
espresso maker brews: Ten cups, 12 cups and fourteen cups espresso
maker. Functions added to many programmed coffee brewers currently seem endless.
Coffee grinders are yet another crucial and integral part of making the best cup of joe
