Dave - "My God, it's full of stars! "
Desktop robots are becoming more and more popular, ie a companion that breaths the midnight "Rosin" solder flux with you.
I present Dave , who is of monolith persuasion.
Very loosely based off the HAL 9000 charater in the 2001 film.
His aim in life is to pulse a comforting multicoloured "Hello" star burst light beam.
He is a carbon based system ...... yes seriously the black tube is carbon fibre and hids some enameled wire down to his capacitor memory bank.
His top end houses a solarcell, plus miller engine, plus RGB led.
I have tuned the RGB leds to give a pulse effect.
Normal operation is ........ solar engine charges the capacitor bank - after a predetermined voltage the miller sends a burst of power (controlled by a secondary capacitor) to the RGB array. All the leds light (bright) , after 0.5sec blue switches off, after 1 second the green switches off and then the red lingers till the charge is depleted.
Even in cloudy conditions it is pulsing every 3 to 5 seconds.....
With incandescent light (ie the midnight oil type) he is a little more lazy.
Pictures speak more than words..........
Trivia :- Origin of the name "HAL" ....... just increment each charater and surprise-surprise ..
