Are PC and hub ports short circuit protected? |

This made me wonder about the first circuit agian, and I double checked that D+ and D· were connected correctly there, which they were. But I had managed to switch ground and VBUS. No wonder the USB cable became slightly warm while connected · it short·circuited the USB port... Fixed this and the first circuit worked too.

Step by Step Procedure to Build Electronic Circuits/Circuit

So let us now get into designing a simple AC,DC regulated power supply circuit to drive a LED. Steps in building the circuit. Step 1: Circuit Designing. To design a circuit, we need to have an idea about the values of each component required in the circuit. Let us now see how we are designing a regulated DC power supply circuit. 1.

Automatic Window Blinds Controller (PICAXE) : 16 Steps (with

I designed and built a modified circuit of the blinds controller for a friend to use with window shades! Two motors were used (One for each window shade)! They were simply wired in parallel! I used an IR detector and the PICAXE remote control feature with a universal remote controi set up to send the required Sony codes!


An automatic gain control circuit 38 is used to set the correct operating levels and thus the distance between the transmitter and receiver antenna for proper operation. The standard pulse generating circuit 44 produces a signal with a setable pulse width at a repetition rate determined by the incoming signal from the conditioning circuit 36.

Controllable Power Outlet - SparkFun

The control board is fairly straight forward- The coil within the relay requires up to 80mA- This is more than a GPIO pin can handle (20mA by default) so we use NPN transistor as a controllable connection to ground-


The microcontroller based automatic changeover consists of power supply circuit consisting of step`down transformer, rectifier (full wave bridge), filter capacitor and the voltage regulator(all ___
