Indoor “solar pendulum” with delayed early morning auto-start and with
extended action till the late evening.
This toy has been inspired by Youtube users “lidmotor” and “smartcreatinos2010″ and others.
The basic electronic circuit is adopted by solarbotics toy “solar pendulum”.
But there were made some improvements around this.
The toy consists of following parts:
a) Homemade DIY solar panels from solar cuts
b) big capacitor 4 Farads / 5.5 Volts unit (Golden CAP)
c) constant current source 0.5 mili Ampers
d) self starting, synchronised low frequency oscillator
e) many turns of wire in inductance (air coil)
f) repulsing the neodym magnet pendulum
How does it works:
Early morning after sunrise daylight produces only small (cca 1 – 2 mA) current in solar panels.
Whole this current “flows” into big capactior unit.
But the voltage on big capacitor unit is not enough to start oscillator and the big
capacitor unit is slowly filling by this current. It lasts approx 2 hours.
When the voltage on big capacitor unit is above 1.7 Volts, the constant current source
allows to supply 0.5 mA to oscillator. Oscillator (with period of 9 seconds)
switches on/off the inductance (coil) and the neodym magnet on pendulum is “pushed”
and pendulum starts to move. Moving of pendulum synchronizes back the
oscillator and the “pushes” goes more and more frequently.
When the day goes on the light on solar panels produces more current.
Some of current is consumed immediatelly by oscillator (and pendulum), the rest of current
is accumulated in big capacitor unit. The volatage on capacitor unit goes
to 6 Volts and is limited by Zener diode (not to go higher).
The volatage on capacitor unit varies from 0 to 6 Volt but the constant
current source gives only 0.5 mA to the oscillator. Pendulum moves and is in
After sunset solar panels produces almost nothing, but big
capacitor is full of energy.
Then starts the dark phases of pendulum. Energy from big capacitor unit
is enough to supply the oscillator approximately 4 hours in the dark.
At 24:00 clock the voltage on capacitor unit drops below 2 Volts
and current source is not able to supply the oscillator and the
pendulum moves less and less. And finally the pendulum stops.
Early morning whole cycle starts again.
