okay so here is the basic ins and outs of it Currently i am modifying a Wii u console to be a single screen hand held unit that has full functionality of the original console with some added capabilities.
I have absolutely no experience in electronics, fabrication, engineering, or design just a strong curiosity on making this project work.
but no one had exactly what I was looking for.
Included is a basic and i mean basic top design and my progress thus far.
Progress to date...
1. Ripped apart an old Sony vio laptop and harvested the screen from it (not much else was useful)
2. Located the appropriate mcb from eBay and purchased along with recommended speakers.
3. Purchased GISSARAL 35000mAh Power Bank Portable External Battery Charger for Surface Pro 4 Book Pro 3 Pro 2 RT. and removed cells from original housing.
4. Purchased alternate fans to remove heat from enclosure once built 2 of Cooler Master Sleeve Bearing 80mm Silent Fan for Computer Cases and CPU Coolers.
5. Removed and broke down original Wii u console from its enclosure & removed original heat sink(see picture for reference) for modification later.
6. Wii u Has been modified to run Wii U Backup, vWii Backups, GameCube Backups, and several retro arch emulators.
7.Other items purchased include longer cable to place optical drive to the right of the console motherboard as opposed to stacked on top, and a short 90 degree to 90 degree
HDMI cable to be plugged into the console and monitor while in handheld mode.
8. Broke-down pro controller
In the end the modified console will be able to be plugged in to the wall outlet(for power) and HDMI output to the TV and played as the original console(CONSOLE MODE),
and yet be able to be unplugged and ran off of the internal power bank at aprox. 4-6 hrs of battery life(untested)(Portable Mode). While in PM it will also have a kickstand to allow
local multiplayer and to accommodate vwii functionality as I will have a sensor bar built into the front of the console
What still needs to be done...
1. Construct a case most likely out of walnut, or possibly out of resin cast & make appropriate vents, slots, and holes for all components
2. Wire Fans to console motherboard via original fan control port, either both fans to the port or one to the port one to a 5v usb plug not sure if the stain on the system is too much (again not an electrical expert).
3. Modify the heat sink to allow clearance of other components and to keep build thickness to a minimum.
4. Add copper heat-pipes to dissipate heat from heat sink to fans (this step will include "fusing" copper heat pipes to the aluminum modified heat sink, no clue how to do this).
5. Add spdt to cut off power to monitor, and power bank while in console mode.
6. Solder direct power from powerbank to console motherboard pins under power plug.
7. De-solder AV/ Wii sensor plug to allow for direct solder of sensor bar to console motherboard.
8. Move power bank control board from one side to the other to allow charging access.
9. Hard wire power for pro controller from console front usb
10.Split Pro controller components and extend out buttons half to one side ( Left stick, directional pad, Left bumpers), and the rest to the right of the console build( Right stick, Right bumpers, A,B,Y,X, Select, home, Start, Power)
can theses be extended? can they rotated? or remapped the buttons somehow(see pictures) should I place the whole board on right and only extend the left stick to the left side of the build.
this is really what I need the most help on and I am open to suggestions, I'm really hoping someone can help me with this
I will add more pictures later if people require.
Update # 1
After alot of thought and tinkering I have tested the pro controller pin out and had what I would say is success.
I was able to connect wires to the face of the pro controller board and duplicate up, down, left, right, a,b,x,y quite simply by touching tinned wires to the separate contact points
and then back to the other end of those wire thus completing the circuit.
My hope is to be able to solder wires to each of the copper button points and extend and duplicate the plates configuration wherever I want in the new housing once built
#2. Wire Fans to console motherboard via original fan control port... Done!
I have decided to only wire the one directly to the console MB and wire the second one to the power bank 5v USB.
#9. Hard wire power for pro controller from console front USB. Modified!
I have decided that because the Wii U pro controllers have an 80hr. battery life I will leave the battery pack in and instead create a way to occasionally charge up the pack externally. skipping any extra strain on my internal power bank that is already running the console, monitor, speakers, and fans.
#10.Split Pro controller components and extend out buttons half to one side, and the rest to the right of the console build. Getting there!
can theses be extended? yes. can they rotated? yes. or remapped the buttons somehow(see pictures) no need to.
at least for me I think I've got a solution for these problems it would seem they can, or in at least my primitive knowledge I can make it work.
I had a thought to sync joy-cons from the Switch(Via MyMateVince's method from YouTube) and have them slide onto rails into the case housing but nixed the idea simply because I like the parts on the pro better and thought the joy-cons might cause me more issues on down the road... plus they are $80 and I'm not willing to spend that when I have other options right in front of me.
Worked on the layout of the whole portable and I have included (See pics)
as always help me I'm fumbling in the dark. I am always willing to take advice or help from those who know. Seriously please comment if you have anything add method or experience wise.
Update # 2
Okay so its been a few days and I've re-thought a few things.
Having the pro controller built in is a great idea but it breaks down when actually trying to use portable functionally, in that you have to use the game-pad to navigate and select content initially, and then switch to the pro controller setup
for this reason I have decided to include the game-pad in the design of the original build essentially having a "DS" type look.
I also came across a post on gbatemp I believe, that outlined a way to modify and remove the optical drive and converting to an all digital library, which is something I think I will attempt as I really dont have any need for the optical drive and it
will also help to reduce total weight in the end product.
Today I did some amazon shopping and picked up a few odds n' ends
1) new thermal pads for the CPU,
2) four 9 inch flat copper heat-sink tubes,
3) thermal epoxy to bond heat-sinks for better thermal dispensation
4) the kill switch to cut power between portable and console modes, 1NO1NC SPDT rated for 5A and 30Vdc (Wii U only requires approx. 15V and I believe 3A)+(the other components)
5) a spare after market pro controller to use for parts,
6) square copper pads to put on the end of the heat tubing for greater surface area at the point of the fans
7) and a larger battery for the actual Game-pad itself
I also determined which pins on the under-side of the Wii U motherboard are needed to hard wire the sensor bar while in vWii mode. This location is important because I will need to de-solder the sensor bar/ composite junction and solder just the sensor bar back to
the motherboard. also that connection is bulky and redundant as I am running audio/video via HDMI.
I am also brainstorming whether I should use low profile USB to hold my digital content, or wire a USB to SDXC card reader and use SD cards more like the switch game carts.
If you have any input or features you think I should include that I have overlooked please feel free to post, and let me know your opinion. Currently at the time of writing this the switch scene is on fire so my console build is slightly obsolete but ehh who cares.
