This project has got several functions as follows:
1. it is an LED desktop light while studying or can be used as monitor light.
2. it is a pen holder on des-top.
3. it is a cell phone stand, or holder and a cell phone USB charger, it charges the cell-phone as soon as you connect the cable to your cell phone.
4. There is a hidden flash drive that has no way to be detected by the computer, unless you trigger the LDR sensor by an external single LED flash light. The flash light generates a small signal on the LDR surface and that small signal is enough to BASE Biasing of the transistor to allow a significant current through the relay coil and turn on the positive DC source for the flash-drive.
A PDF map and detail, with calculation of this project is available and you can download them for free.
