PSP 1000 Moddings USB charging By: Wesley



First disassemble your PSP all the way down to the motherboard, and remove the motherboard, here's a nice start...



Once you have removed the motherboard from the PSP turn it over. Here's the area on the motherboard you'll be working with...



The first point you will need to solder is at the USB port. Fitting the wire into the tight areas around the USB port is easier if you bend your wire a little so that it travels between some of the other components on the motherboard (as you can see above). Here's the solder point at the USB connector...



Next you will need to solder the wire to the power connector. Here's the solder point for the power connector...



Now let's test it out! Put your motherboard back into the PSP, hook up your power board, and insert the battery. Now hook up your USB cable like you normally would for data transfer, now look at your Power LED. Did it light up Orange like it does when your PSP is charging? If so then then that means that your new mod works!



Here you can see there's no battery in and no power plug, just the USB, and it's on and running...

Now put your PSP back together and enjoy it's new charging capability! You can also continue on to the companion tutorial for this mod, and convert your AC Adapter to a USB Charger!

Set PS1 Controller as PSP Controller by ACIDMODS

Soldering to the Powerboard

For the X [] /\ and O buttons, I found it easiest to solder through the vias on the powerboard. If you use 30awg wire you can run the wires under the board and poke the wire up through the holes, then just apply a little solder and trim away any excess wire. For the button bar connections it is similar, except these are blind vias, so you have to go through the top.



The picture below shows the connector pinout for the cable that links the powerboard and motherboard. A good solder point for the right trigger button can be found at one end of this connector, as well as alternative points for the other powerboard connections.




Soldering to the D-pad

I use a cheap ($15 at RadioShack) "helping hands" soldering clamp that is very useful for this type of precise work. It has a set of gator clips and a magnifying glass on adjustable arms, plus a soldering iron holder that I continually burn myself on.

To begin, clean the pins on the back of the connector with some rubbing alcohol. Next apply a little flux to the pins you are going to be soldering to. Because the pins are so small and close together, I decided not to add any solder to them directly, as it is very easy to bridge them with excess solder. So for each of the five points this was the basic procedure:

•   Strip a short amount at the end of the wire
•   Dip the stripped end in flux
•   Melt a small amount of solder onto iron tip
•   Touch the tip of the wire to the iron to transfer a small amount of solder
•   Dip tinned wire end back into flux again
•   Clean all excess solder f-rom iron tip
•   Hold the wire firmly in place against connector pin with tweezers
•   Carefully touch iron tip to the back of the wire (the flux on the wire and pin should help the solder bond quickly with the pin)
•   Hold the wire very still for a couple seconds while the solder cools
•   Inspect under magnification to ensure there is a good bond and no bridged pins

Once all the wires are soldered its a good idea to check everything again with a multimeter, then adjust your wires so they will not interfere with the fit of other components (picture 2). I applied a little superglue to the wires to secure them to each other and keep them in shape.




Soldering to the Power Switch

This may be useful if you have a broken power switch and want to send the On/Off/Standby and Hold functions out to an external controller or switch. The switch basically works like the other buttons and activates these functions by grounding pins 1, 3, or 4 to pin 2. The power on/off and standby functions are all activated by pin 4 when grounded to pin 2 (power off or standby is determined by how long the switch is held in position.)




Analog Stick Contacts

The joystick contacts on the motherboard can be wired to external potentiometers to provide analog input. If you aren't familiar with how this type of potentiometer based joystick works, here is a basic summary.

Potentiometers are variable resistors, inside them is a resistive material with three pins connected to it. On either end of the resistive material are the power and ground pins, these typically remain at a constant voltage. The third pin is called the wiper, this is just a piece of metal that can move along the resistive material (in this case the wiper is attached to the arm of the joystick). As the wiper moves closer to ground the voltage read from this pin approaches 0, as it moves closer to the power input the wiper voltage approaches whatever the supply voltage is. When the wiper is directly in the middle, its voltage will be half of the input voltage (in accordance with Ohm's law). By reading the voltage on the wiper pin, the psp is able to determine the position of the joystick at any time.

Two different examples for providing analog input are shown in this post, one using an MCP4251 digital potentiometer, and another using hardwired Ps1 controller joysticks. When looking at your PSP motherboard in the way it would normally be oriented while using the PSP, the analog connections are as follows:

  [[ ]  ]  =GND
[  [ ]]    =X-Axis
  [[ ]]    =+2.5v
[  [ ]]    =Y-Axis

The 2.5v supply to the joystick is not constant, but pulsed for approximately 200µs at 130Hz, this can be seen in the oscilloscope view below. These 2.5v pulses are only present when the running application requires input from the joystick, otherwise the joystick supply will be at a constant 0v.



Using a Microcontroller to Interface a Ps1/Ps2 controller to the PSP

The following code written for the ATmega168 microcontroller (should also work with the mega48 and 88) allows a Ps1/Ps2 controller to be used to control a PSP through wires soldered to the points shown in the images above. An MCP4251 digital potentiometer is also used to provide analog input. The benefit to this approach is that any Ps1/Ps2 controller can be used without having to modify the controller in any way, so wireless controllers can also be used. I still need to draw up a connection schematic and write a proper description of this, but for now here is the code.

Hardwiring a Ps1 Controller

As an alternative to reading and interpreting data f-rom the controller, it can also be modified to act as a set of independent switches with parallel output. This will result in the controller no longer being usable as a playstation controller, so it is only recommended for controllers which are already defective. The following image shows the pinouts for rewiring a Sony SCPH-1200 Ps1 Analog Controller for a point to point connection to the PSP, with the addition of a modified right analog stick (A2D mod) to mimic the X, [], /\, and O buttons.



The Ps1 controller and the PSP differ slightly in the way the analog stick is grounded, so some simple modifications will need to be made to the controllers PCB for it to work. This may involve cutting traces, desoldering components, or bridging points with additional wires. It’s difficult to be specific here because Sony seems to change the PCB layouts on their controllers a lot. What is important is that the pins on the potentiometers (3 on each) are wired and grounded according to the diagrams above. Keep checking all of the pot pins with a multimeter, and make any necessary modifications until everything is correct.

The points labeled A1, A2, and A3 on the left analog stick will be wired to three of the four contacts on the PSPs Analog nub or the motherboards analog contact pads. The remaining contact should be grounded with the other buttons. So, when looking at your PSP motherboard in the way it would normally be oriented while using the PSP, the analog connections are as follows:

  [[ ]  ]  =GND
[  [ ]]    =X-Axis (A1)
  [[ ]]    =+2.5v  (A2)
[  [ ]]    =Y-Axis (A3)

The wiring of the right analog stick shown in the diagram is optional, and allows it to perform the same function as the “Razor Nub” on the PSP. This will require some additional work beyond just rewiring the solder points, to make the potentiometers function like simple momentary switches. You will need to desolder the right analog stick, remove the potentiometers, and cut away part of the conductive track inside them. This is all much easier than it sounds, and TimmyDX has made an excellent video tutorial on how to do it.

As I mentioned earlier there were many different hardware revisions to these controllers, so yours may not look exactly like the picture, but the basic ideas here should be applicable for most Ps1 analog controllers. I think it is safe to assume that the pin order on the ribbon cable connector should be the same for all Ps1 controllers which use the membrane button contacts, but I am not 100% sure of this. The early Ps1 Analog controllers have the button contacts on a solid PCB, in which case these pinouts do not apply.

The Hack is Back: OS X Fixed To Run on Atom Netbooks

When Apple dropped support for Atom processors in OS X 10.6.2, effectively killing Hackintosh netbooks, we knew that somebody would fix things. We didn’t know that it would happen so fast.
Just over a week after the update, Russian hacker “Tea” has made a patched kernel specifically for the Atom CPU. Simply copying this to the root level of your drive and rebooting should make everything work just like it did in 10.6.1. Of course, if you are suffering the endless gray screen on boot that characterizes the problem OS, then you’ll somehow need to get into the hard drive from the outside, perhaps by booting from the DVD or USB stick you used to hack your Mac in the first place.
Tea himself didn’t actually test out this kernel (which is the very lowest level of the OS) on 10.6.2, but some brave (desperate?) folks at the Insanely Mac forums tried it and it apparently works fine.
My Wind Hackintosh is still running the previous version of OS X 10.5 Leopard. I see no reason to update it, especially with all these shenanigans.

Abuse iPhone gets Polished to Perfection


The iPhone is a beautiful piece of hardware but a few months in your pocket along with those keys and coins is enough to scratch it up. Now, instead of toting a clawed-out piece of hardware, you can apply some elbow grease and restore it to near perfection
Hack n Mod has posted a cool tutorial on how to give an abused iPhone a fresh out-of-the-box look.
To fix scratches on the back,  you need to gently dry sand it, then add some water to wet sand and polish it with a 3M Headlight Lens Restoration Kit. The detailed step-by-step pictorial offers information on what grit of sandpaper to use and how to get the mirror-like finish.
The only catch is that the Apple logo at the back is erased in the process but that’s a small price to pay. And it’s not like anyone can mistake the iPhone for another phone–whether Apple’s logo is on there or not.
Fixing scratches on the display is a little more tricky because it involves getting a replacement top layer but that’s available on eBay for $10. Just follow the instructions to open up the front cover and its simple enough to do.
The technique doesn’t apply to just the iPhone. You can take any scratched-up phone and polish it to get a new look.

Laptop is Dead. How to Troubleshoot the problem by LaptopRepair101

In this post I’ll explain how to troubleshoot a dead laptop and find the problem. The following troubleshooting tips are not model and brand specific, they should work for most laptops.
Let’s take a look at two different scenarios.
Example 1. The laptop is absolutely dead.
When you plug in the power adapter and press on the power button, there is no signs of life at all. The laptop will not make usual noises, LEDs will not light up, the fan will not spin, the screen is blank and black, etc… In short, the laptop is dead.
What you can do in this case?
1. Make sure the wall outlet is working and the laptop DC adapter is getting power from the outlet. Try another wall outlet.
2. Test the laptop DC power adapter, make sure the voltage output is correct. You can test the DC power adapter with a voltmeter.
3. Let’s say the DC adapter is fine and the adapter outputs correct voltage. In this case unplug the power adapter from the laptop, remove the battery, wait for 1-2 minutes, plug in the adapter and try turning on the laptop again.
OK, you tested the adapter and it’s bad. If you decide to replace the original DC adapter with a generic one, you’ll have to follow this rule:
The voltage output on your new adapter has to be exactly the same as on the original adapter. The amperage on the new adapter could be the same or higher.
If nothing helps and the laptop is still dead, apparently the motherboard is fried or there is a problem with the DC power jack. It’s possible the DC power jack is broken and the motherboard is not getting any power from the adapter. In this case you’ll have to disassemble the laptop and replace the power jack. Check out this guide for fixing laptop power jack.
Example 2. When you plug the DC power adapter and press on the power button, the laptop starts making normal noises, the LEDs work properly but noting appears on the screen. The laptop will not start.


Troubleshoot dead laptop

First of all, take a closer look at the LCD screen. Look at the screen under bright light. It’s possible that the image is still on the screen but it’s very faint. If that’s the case, check out these tips for troubleshooting laptop with backlight failure.
Connect external monitor
If there is no image on the laptop LCD screen, test the laptop with an external monitor. Connect an external monitor to the VGA port on your laptop and turn the laptop on. You can toggle video output between the internal LCD screen and external monitor by pressing Fn and F4 keys simultaneously on HP laptops, Fn and F5 keys on Toshiba laptops, Fn and F7 keys on IBM laptops. Other laptops may use different key combinations.
Let’s say the external monitor works fine but the internal LCD screen has no image at all. If that’s the case, your problem could be related to the LCD screen or the video cable. Also, make sure the video cable makes good connection with the motherboard and the LCD screen. Try reconnecting, reseating the cable.
Test external video
In my case, both internal and external monitors were absolutely dead. Neither of them had image. That means the problem is not related to the LCD screen or the video cable. From my experience I know that this problem could be related to the laptop memory.
Replace reseat memory module
Try reseating the memory module, maybe it’s not making good connection with the memory slot. Try cleaning contacts on the memory module with pen eraser. Try moving the memory module into another slot. Try replacing the memory module with another known good module, it’s possible that your original module is dead.
If you have two memory modules installed you can try removing them one by one, it’s possible that one of the modules is bad. Try installing different memory modules into different memory slots.
In my case reseating, swapping the memory module didn’t help. I was pretty confident that my problem is not memory related and I moved on.
Remove hard drive DVD drive
Try removing battery, hard drive and DVD drive and turning on the laptop without these components.
Disconnect display
Also, try turning on the laptop with an external monitor when the video cable is unplugged from the motherboard. If the laptop start with video on the external monitor, apparently there is something wrong with the laptop display panel.
Remove laptop components
In my case removing the hard drive and DVD drive didn’t help. Unplugging the video cable didn’t help either.
I continued taking my laptop apart piece by piece and tested it after each step.
I removed wireless card, modem, disconnected the keyboard but it didn’t help.
Test laptop with external monitor
I still wasn’t able to boot the laptop with video on the external monitor.
Disassemble laptop
Finally, I disassembled the laptop and removed the motherboard.
Test laptop motherboard
On this picture you see my final test. The motherboard has been removed from the base and I assembled basic barebone system on my bench.
1. Motherboard. Like on most laptops, in my case the video card is integrated into the motherboard
2. CPU with heatsink and cooling fan.
3. Known good memory module.
4. The power button board witch I need to turn on the system.
5. Working DC power adapter.
Still cannot get any video on the external monitor. The system turns on, the cooling fan starts spinning but there is no video.
At this point I’m 95% sure that the motherboard is dead. CPU failures are not very common, so it must be bad motherboard.

Preparing The Cable
 




















Peel off some of the orange insulator. About 3-4 mm should do. Under the cover, there are eight wires in following order: GND, DATA1, DATA2, GND, GND, DATA3, DATA 4 and GND. Ground wires are not insulated.





















Because the two wires in the middle are both GND, they have to be soldered together to pin 4 of the connector. That is because the connector only has seven soldering pins.

Position the peeled wires on the pins so they can be soldered easily back to their places. NOTE ! I recommend using soldering assistant because soldering those thin wires can be just plain hell. Especially if your hands tend to shake a bit









































Position the cable on table / soldering assistant so that the connectors are as shown in the pictures (proper connector orientation in both ends are highlighted in the image with white color)





















Put the rubber coating back on and attach it to its place with small drop of super-glue or epoxy. If you want to have a strong cable or just want to make sure that the solders hold, I recommend that you cover the soldering pins with hot-melt glue as they were in the beginning.
