This is my 2016 competition entry. I've enjoyed participating so far, thank you Bitbuilt for hosting this opportunity. All the builds are looking great, good luck to all the participators finished and still modding!

June 19: Cut up an original DMG case and super glued the 3DS pieces in.

June 19: Lather it in epoxy

June 23: It’s a tight fit. The 3DS sliders basically rubbing against the batteries.

June 25: Relocating the NAND took a few hours but the rest was standard.

July 1: Primed

July 12: Mounted the controller pieces in the front case. I used magnet wire for this as the batteries are basically touching the front half so I will have to keep this tidy.

No Spaghetti wires.

Transistor for the volume minus button sync mod. Thanks to Aurelio for helping me with this during my first Wii portable.

The trimmed GC controller and the audio amp.

Stacked two transistors on top of each other to make the low battery indicator. The potentiometer is adjusted so it turns on at 6.2v which I found is the perfect setting for the Panasonic batteries.

The LMAO trim. I opted on using an SD card reader instead since it is low profile and fits nicely right on top of the motherboard.

I wired it up so that way the motherboard can be removed very easily from the case. The fan sits tightly in that box I made which holds the motherboard in and keeps it from shaking around. Now I don’t have to secure it permanently which made it very easy to do work on it.

I didn’t have room for the typical heatsink/fan setup so I got this method from ShockSlayer. It is essentially just a metal fan stuck on the Hollywood and a tiny chunk from a GC heatsink stuck on the Broadway. It draws in air from the back of the case and pushes it out right through the top. I used a plastic screen covering the ventilation cut. Being a stupid small cooling setup, naturally it is not as efficient as a typical setup. However, shown from the IR scans, the outside of the case peaks at a safe temperature. The IR camera detects radiation so it is like x-ray vision. The white heat spots on the case are where the regulators are located on the inside. The Ti regulators are rated for 185F so the temperature is in range. The batteries remain cool and all the heat is located at the top of the case, away from your hands too. This picture was taken 3 hours into Melee.

The Wiiboy rev2:
-LMAO trimmed Wii
-4 voltage regulators. 1v, 1.15v, 3.3v, and 5v (just for fan)
-6800mah Panasonic batteries
-3.5” screen
-3-way on/off switch for charging and wall power through same jack
-Switching headphone jack and speakers
-Double-tact modded shoulder buttons
-Z button made using actuator from clicky tact on top of soft tact from an original GC controller
-Volume minus doubles as sync button (why clutter a small case with buttons that are not used often)
-SD card reader (running off 3.3v)
-Low battery indicator active around 15 minutes left

Dang, nice! Glad you finished, hope I can too :P
Well I finished the wiiboy rev1 really early on so I started this soon after to improve on the shortcomings in the original design. but yeah, not a lot of time left until it's over!

Looks awesome. Glad to see the LMAO trim get a definitive portable showing what it's capable of.

Eventually I'll be testing that heatsink/fan setup myself, but in the meantime Gman's results are very promising!

I love the LMAO trim, it isn't all that bad to do really and it's powerful for sure.

Well done! Excellent frankencasing and paint job. The internals are neat, and seeing the LMAO used is nice as well. Having 4 cells is a nice improvement too. Im sad to see the GC style buttons go, but the DS ones look nice. Cool fan, looks like the same one in SS's for sale post a while back.

Also, nice fan grill ( ͡° ͜ʖ ͡°)

So what I'm getting from this is you can do away with the 5v reg if you are okay with the usb to sd card reader that can run on 3.3v, and you plug your fan into 7.4?

Well most likely your fan will be rated for 5v, but most will still be efficient running from 3.3v. You can always just use an AMS117, no need for another Ti reg in most cases. The AMS117 can be bought in bulk for pennies each. I would still recommend using a USB port since their are more options and uses

Wow. Beautiful.

Love the clean look, and the fact it's a DMG. All so nicely finished, I love seeing clean internals and neat layouts.

This is very nice, I like everything of it! The only thing that I think that you should have done is using a shielded wire for the video line :)

I've seen the effects of interference on previous portables that really needed it. However this design did not demonstrate any symptoms of interference on the video or audio so I didn't bother with using thicker cables.

Why thicker?

Shielded wires = thicker. Compared to nonshielded wires. That's my interpretation.

Yeah. And regardless of how thick they are, it's just one wire. Hmm.

I'm agreeing with you. And I'm saying, even if they were thicker, it's just one wire, so it could have easily been included. I guess he really must have no interference whatsoever.
