Here is a simple and incredibly fun USB hack where you turn an old CPU into a hot plate for your coffee, tea or some liquid fragrance [in a dish].
This very useful USB hack can be done in 4 steps.
Step 1) Tools and Materials
1. A dead CPU. (Ofcourse you can use a working one but it wonâ€™t be feasible.) 2. A USB cable 3. A Fan grill with screws. 4. Any box (I used a wooden tie box cover) 5. A rotary Tool (the best tool ever invented) 6. Epoxy 7. A creative artistic mind…[continute]
Step 2) The Idea
A CPU will still have some working electronic circuits even if it stopped functioning probably. And this project will use the heat generated by running some Volts in the CPU through a USB cable.Â First things first. Be Very Careful. Connecting a malfunctioning CPU to your computer may and will damage your computerâ€™s ports or even worse. If you donâ€™t have enough…[continue]
Step 3) The Steps
First, prepare the base. You have to find a thin box or a box cover to use as the base of the plate. I used a tie box cover made of wood because it has the same thickness as my laptop. Now put the CPU over the base you picked and mark a square to drill with your rotary device. The square must be a little bit bigger than the CPU. The reason behind the bigger hole…[continue]
Step 4) Preparing the hot plate
locate the ground pins in your CPU and that can be done by reviewing the CPU data sheet or simply by the devastating trial and error. Cut the USB wire and pass it through the hole you made previously in the base. Strip the USB cable and locate the black and red weirs (black wire = ground, Red wire = +5V). You can cut out the white and green data weirs for more space…[continue]
