Brainchild Solar Engine Package
This proprietary Brainchild Solar Engine powers many of your Solar Robots. It can also be used to convert (from battery) several commercially available toys within or slightly above the voltage range of the Release Voltage Mechanism.
Converting the "HEX Bug" or the "Tomica Bit Racer" allows you to enjoy these toys without ever needing another battery! Simply remove the batteries and attach the motor wires from the Brainchild Solar Engine to the correct leads in the battery compartment on the "Hex Bug" or the "Tomica Bit Racer". Presto, you have a toy that will work endlessly if sufficient light is available to charge the capacitor.
We estimate the "HEX Bug" can walk about 2 kilometers in a day in direct sun...how far will your bug walk?

How does it work?
There are four options for completing the solar circuit on the back of the Brainchild Solar Panel. The package here contain electrical components for the Solar engine circuit.
The difference with this circuit to others is with our selection of components, they have been experiment and tested to let the voltage charge up to 4.5 volts in the shortest time possible (like a couple of minutes under a 25W desk lamp) without damaging the electronics. To get an idea of the power available from this solar engine see the Tonado Bot on this website and for future turbo charged upgrade with the same circuit see the Combat Robots in action on this website.
The beauty of this package is that It is a complete package with minimal fuss, just solder the parts directly behind the solar panel and attach the motor wires of your toy to panel and you will have a very powerful freely available electrical source for your toys or robots.
(Note: capacitor will be charged to 4.5V and released, if you are not sure about whether you toy can take the voltage, you should buy the motors Ref:EM01 on this website which have been tested with this circuit and you can freeform your own solar robots)
- Voltage Trigger System: When the solar panel has charged the capacitor (a device which stores electricity} to a threshold level of 4.5 volts, it will be release power to the motor and drive your robot/toy. There is no need to turn the robot on or off as the charging is continuous and when the threshold is reached the energy is discharged and the toy will move according to its function. This works with the Tornado Bot, Yo Bot or other commercially available toys.
Solar engine circuit diagram
Brainchild Solar Engine Package contains:
- 1 - Solar panel with proprietary printed circuit on back
- 1 - 3904 NPN Transistor,
- 1 - Diode
- 1 - Voltage Trigger (If you are purchasing the solar panel by itself and will be applying it on a HEXBUG, please specify on your purchase order, a Voltage trigger for less that 3 volts will be provided in the package instead)
- 1 - Small capacitor for timing the voltage trigger (Black)
- 1 - Main storage capacitor (blue)
Complete instructions are included.
Advantage over the LED Trigger Solar Engine:
This system of solor engine is much more stable than the LED system because it is not so much depandent on the motor that you find. It will drive nearly all motors.
Plus because the circuit has a diode in it, it will save the electrical energy charged by the solar panel without using it up on an LED. It will accumulate untill the voltage is high enough to be release.
We found that the LED circuit is also very much determined by the strengh of your light source, meaning that under low light situations the above circuit will work but the LED circuit will never work because it has not reach the LED release voltage because the LED is using it.
