If you want to make this project, keep in mind that I had some mistakes during making this project: 1. i forgot the resistors for LEDs, you should use resistors for LEDs to save your battery charges for long time. 2. Those solar boards are each 1.4V with 350mA current rate which are not powerful enough to push the charges into batteries, you should use 3 or 4 of them. In the next project I explain this more with correct practical examples. 3. Calculate and install a resistor for USB charging input because we are not allowed to withdraw more than 500mA of current from a USB out put. 4. Batteries are not for ever, you should install them in away to be easily replaceable after a year or 2, max 3 years. 5. Make it beautiful with a good carpentry and design, do not make as ugly as I did, you better drill the HDD platters and install LEDs directly on the surface. 6. if you use this project for study only, you should use a white plastic board, not a transparent plastic board that I used, it will disturb your eyes during study. 7. an advance project of this type with very correct engineering calculations and circuit installations would be coming soon, you better make that one if you really want to make one.
