Tut: Modded N52te, 2016 Edition

Modded N52te 2016 Edition


Introduction:

I know N52te is quite old already.
I know it is quite hard to get your hands on N52te nowadays.
I know there are other alternatives already and some of those even have cherry switches.

But I don't care. My N52te is starting to be a little worn out and I thought instead of doing hot glue fixes I would make a completely new modded one. I still had one N52te in unopened box, so why not. And as I have said, I never write anything twice. So that's why there is a new evolution this time also.

Here are some key points:
- Complete custom PCBs where needed with through hole preferred design.
- Custom redesigned 3D parts for 3D-printing.
- Near zero dremel usage for more "real" product look.

If you are still at least a little interested about modded N52te, make your voice heard on this thread. This is the last thread I will make about this, and after I'm done I won't revisit this anymore.

Cherry conversion

1. Requirements

You need to buy the following parts:
 - Custom PCB [link]
OSHpark is probably the easiest place to order these, but it is not cheap for this size boards ($47.80). I ordered mine from china for under 20 / 5 pieces. I can give gerber files and info about the shops if you want.

 - 3D printed frame [link]
If you have a 3d printer you can try to print these yourself. However I highly recommend you to not do it. These were not designed to be printed with filament printer. I ordered mine from i.materialise.com. Printed as polyamide and dyed black. All the dimensions seem to match, so I can recommend this to others.

 - x14 Cherry MX switches.
The switch type whatever you like.

 - x14 Diodes.
Pretty much any basic through hole diode like 1N4148 will work. I accidentally used zener diodes, don't do that yourself...

 - (optional) x14 3mm LEDs.
Any color you like. Check the current and voltage ratings for the leds. You will need those to calculate the correct resistors for those.

 - (optional) x14 resistors for the leds.
Use some resistor calculation tool to calculate the correct resistors (like this: http://ledcalc.com/). The supply voltage is 5V and the leds are connected parallel.


2. Open the N52te and remove the key board

There are screws on the back. One is under the thumb key rubber pad and another one is under joystick rubber pad. The rest are visible without removing anything extra.

Desolder the 10 wire ribbon cable that goes to the keypad pcb. After all this you should get this part off of the device:


NOTE: do not cut the ribbon cable like I did. You need it full length.

You got it? Good, now trow it away, because we are going to replace it.


3. Solder the diodes (and resistors)

Solder the diodes and resistors to the pcb. If you dont need the diodes, then dont solder the resistors. There are markings on the board. If you are in doubt, check the pic.
Important note: The legs of the components can not be longer than 1mm on the front side of the board. Otherwise those will hit the frame.



4. Trim the printed frame

You can skip this step if you ordered the parts separately.

I have made a version where the frame and bottom parts are connected with struts. This is because usually there is a minimum price for a single print. This makes it cheaper to print.

The struts are in red on the render:



5. Place switches

The switches are installed "upside down". Meaning the leds are on the top. If the holes are too small, use a file. Holes on my print were prefect size.



6. Combine these two parts together

You should be able to fit these 2 together now. Make sure you press these together completely. If you didn't trim the legs of the resistors and diodes short enough, this is the part where it will be a problem.


7. Add leds

Next put 3mm leds to the switches. Cathode is on the right side, which I guess is also the opposite to the regular way. The max length for the legs is 2mm here.



8. Solder the ribbon cable

After these steps you should have something like this:



Make sure it fits inside the device before soldering the ribbon cable.

Next you need to solder the ribbon cable to the pcb. It is attached the same way as on the original board.
NOTE: On the picture the pads are through hole, but on the design I will give those are SMD pads on the backside. These are in my opinion easier to solder.

Here are pics of my tests:



9. Close up the device

Now you should be able to close the device. Polyamide is quite flexible, so you may need to press the case parts a little to get everything fit.

Cherry conversion can be done without changing anything else inside. For joystick I planned a separate teensy, which would then require external usb hub.

I have designed a clone teensy (with wireless capabilities) which would replace N52te main board, but that is something I am not even sure I can get to work. However teensy 3.2 has enough pins for complete control of the device, so I can make a wiring diagram for those that truly want to deal with annoying wiring.

I'm interested in this thread.  I just recently acquired a n52te and have been reading the old analog joystick mod.  Bought some teensy boards years ago to start a project but never got to it.  Hopefully I can savage those.  Looking forward to the tutorial.

I dropped the extra button on the top. This made it possible to model the whole side as a one part instead of two. The printed models are not as shiny as I would have hoped.

The custom joystick cap is modified cap from the steam controller. It is same dimensions as a xbox 360 cap.

Why don't you do your own thing? Will the base plate and cable still be N52te?

The casing and arm rest are the only things left in the final version. No cable since its wireless.

There aren't enough things wrong with N52te. If I made my own version, it would not be that much different from N52te.

If you make the whole thing you can sell them. I'm sure a lot of us on here would buy one.

Still it would be different and it would be yours. You could kickstart to mold the plastic, Obsiv would surely help you. People cant build this with a long gone keyboard.

You are past Mods.

how much pesos for a w11ce crafted piece? ;)

N52te's in acceptable condition or even new are harder to find than diamonds, unless this mod doesnt work with the new copycats from razer i dont see myself having the chance to go for a mod lol
