MS Xbox One Controller common failures

I get myself intro repairing Xbox One Controllers. I going to write some of my experience about repairing this thinks. Most common problem is the analog stick of course, moving part are the weakest point of any device. You can buy a replacement part for a few buck, but actually you need only the variable resistor part. You can clearly see what is going wrong here, the conductor layer are broked on the left green resistor. If you want cheap fix this stick you should only replace the faulty resistor.

Disassembled analog stick

Another common failure is the board-to-board connector.You can find 2 different pcb inside the controller which are connected by this way.The problem come up when the solder joints cracks.This is because the upper pcb get different kind of forces under in use. The solder joints give up and crack and can't conduct any more.

Broken connector

I attached more example here.

Angry player XD

And here is an interesting thing for the end:
I tested out this controller and it shorty come up that the analog stick not work at all.This was not a potentiometer issue rather that a broken trace on the main board.This was be an angry player or something, but jesusss... How much force does it take to bend and broke the mainboard !!??
On this picture you can see I run a jumper wire to short the broken traces.

(Technical description: The 5K pot of analog stick get 1.8v and acts like a voltage divider [because it is ].Here the pots are gets nothing. The voltage regulator which is creating the 1.8v is working fine. So the voltage can't supply the resistor because the broken trances)

Jumper wires solved the problem

JBC AD2950 Display Backlight Mod

I really like my JBC soldering station, perfect and robous tool. I usually just put the handpiece back to its holder, and after a few minute the station will activate the hibernation mode (no heating). This is a great feature because you don't have to turn on and off the station, but sometimes, for example when your 2 years old daughter start exploring your lab this can be dangerous. If you let the iron in hibernation mode, it is start heating very quickly (5 sec. from room temp.) as soon as you pull the handpiece out of its holder. Fortunately, my daughter dropped down the handpiece in time, and she don't get burned, but this was a terrible mistake as a dad because things could be happen much worse than in my case. The problem is when the soldering station is turned on, you don't get enough visual notification about it. The display are saying "hibernation" of course, but if you tired or you are in hurry, you probably miss it, and you will forget to turn it off.

PCB Plotter a.k.a. Direct Ink To PCB

The simples method to manufacturing PCBs at home is the toner trasfer method.But the laser printer is the most important a part of this technic and the laser printer is expensive stuff for only printing some PCB / month. The cheapest method to manufacturing PCBs at home is using alcoholic pen and drawing the traces with your own hands . But our hands resolution or the precision is not enough in most case. The PCB plotter machine with CNC controlling are the solution of this problem. I spend my last weeks to build this PCB plotter machine from 2 CDROM driver and a floppy driver. The parameters: 38mm*38mm Workspace (enough in most case) 0.0735 mm / steep (in halfsteeping mode) Parts that is used: As I said : 2 CDROM and 1 Floppy driver 3 * L293 Dual Full Bridge Motor Driver IC Power supply of course ATMEGA88 and USB2Serial bridge Some wires and pin headers The full cost is about 15$!! The manufacturing flow I using Eagle Cad for design the circuits and o

Razer GreenSwich issue in BlackWidow keyboard

Recently, I got a used Razer BLACKWIDOW Ultimate 2014 mechanical keyboard with the fancy Razer greenswitches inside. The keyboard looks awesome and I really like the illuminated keys too. I'm not a person who likes the lound, clicking sounds that this switches are make when you press them down but I decided to give it a try. Sadly, the smile in my face went away as soon as I plugged the keyboard in and started typing on it. Every second or third character was doubled or missed on the screen of my computer. Something was wrong for sure with the keys, this issue is called scattering by the way. Actually I know that before I bought the keyboard and this is why I was bought it. There was nothing left, time to investigate the source of this issue. After a few phillips head screws I got inside the keyboard, and I desoldered some of the failed switches. The switch itself was easily disassemblable, 2 securing on each side. The problem was obvious after I looked inside the switch, corrod
