Nokia N900

Turn the phone over so the screen is face down.
Remove the back cover by locating the slit on the bottom of the phone and lifting up.
Remove the battery by lifting it out of the device.
Remove the two "L-shaped" antennas by unscrewing the following screws:
Four screw M1 .4x5.0
Two screw RF1 .4x4
In addition to unscrewing the screws, remove the B-Cover (which will fall right out without the screws).
You will now have two halves of the phone.
Grab the half of the phone that has the keyboard on it
Remove the keyboard by unsnapping the frame and then lifting the pad out from the device.
Place the key pad and cover to the side for the remaining steps.
Use a blue plastic opening tool lift the motherboard out of the back cover
Look at the bottom of the motherboard to find the USB Port
Once Located the USB Port ( Red mark)Remove it and replace it with new one.

Low-Side MOSFET Drive Circuits and Techniques - 7 Practical Circuits

Image
In many circuits, it is necessary to use MOSFETs for switching. In many cases, the MOSFET drive signals are generated by microcontrollers. In other cases, they are generated by ICs – PWM controllers, timers or any IC in fact. However, MOSFETs cannot always just be connected to the drive signal and be expected to work properly. Due to the construction of the MOSFET, driving it is not the simplest of tasks, especially for beginners. There are many users who regularly ask for help on MOSFET drive related issues or problems on different blogs, websites and forums. So, here I will show some MOSFET drive techniques/methods for MOSFETs configured as low-side switches. Before I head on to MOSFET drive, let me just tell you what a low-side switch is, in case you don't know. When the MOSFET (that you're using as a switch) sinks current, it is a low-side switch. The load will be between the drain and +V supply. The source will be connected to ground. Gate will be driven with respect to gr

Using the SG3525 PWM Controller - Explanation and Example: Circuit Diagram / Schematic of Push-Pull Converter

Image
PWM is used in all sorts of power control and converter circuits. Some common examples include motor control, DC-DC converters, DC-AC inverters and lamp dimmers. There are numerous PWM controllers available that make the use and application of PWM quite easy. One of the most popular of such controllers is the versatile and ubiquitous SG3525 produced by multiple manufacturers – ST Microelectronics, Fairchild Semiconductors, On Semiconductors, to name a few. SG3525 is used extensively in DC-DC converters, DC-AC inverters, home UPS systems, solar inverters, power supplies, battery chargers and numerous other applications. With proper understanding, you can soon start using SG3525 yourself in such applications or any other application really that demands PWM control. Before going on to the description and application, let’s first take a look at the block diagram and the pin layout. Pins 1 (Inverting Input) and 2 (Non Inverting Input) are the inputs to the on-board error amplifier. If you a

Simple MW Transmitter Circuit Diagram

Image
Today I'm going to give you a simple MW Transmitter.This transmitter can be operated with 9 v power supply.Here we have used common transistor BF494B.Here we have used MW antenna coil you can use the 8 ohm speaker to speak that means here the speaker does the work of the mic.To get the maximum result build this on a pcb and don't supply power without connecting the antenna.             Note:   Don't missuse this circuit            you can send signals up to 500M
