Working on a small Raspberry Pi Laptop. So far I have stripped the pi of all of its large connectors. I have the USB hub wired directly to the pads. The wifi adapter and dongle for the keyboard are also stripped of there case and soldered directly to the connections.

I have a 7″ screen I will be using for the display. Looking into HDMI switches so I can use an external display.

I finished this project last year for San Mateo Maker Faire but never made a video….TILL NOW!

Been awhile since I last posted but I am pretty much moved into my new place in Houston and getting back to my personal projects.

Assembling the front half of the case. Using size M2 sheet metal screws to attach the PCBs to the case. Holes are tapped with a 1.5mm drill bit before hand. For those that know the PSone screen accepts 7.4V then converts it down to 5V in some areas with a 7805 linear regulator. I removed the 7805s and attached my 5V switching power supply to the pads which dropped the power draw of the screen.

The back side houses much more parts. Batteries, switching powersupply, NES Top Loader PCB, speaker, amplifier, and volume control are all housed here. There is no hotglue in this portable. Everything is mechanically held in place. Some electrical tape is used to insulate parts but that is about it.

The button on the right is supposed to be for an internal MCU (like a MSP430) if I ever want to add more functionality to the portable.

I have some extra space between the front pcb boards and the rear pcb boards inside the case. I will be able to slim off about 1/8″ – 3/16″ off the thickness on the next case.

Like all portrait layout portables the top is a bit top heavy but it still has a good balance because of the thickness of the portable. The controls are laid out in the exact same dimensions as a real NES controller so it feels really nice. It has enough battery power to go for about 10 hours at max volume. I will need to tweak the audio amp a bit however as the volume is a bit soft. Should be able to adjust it by changing two resistors on the SparkFun amplifier board.

Check out the NES Top Loader project page for more details.

The case I designed and Chris printed showed up today. This is the prototype case. I had to make some slight tweaks to the design to get it ready for the final version.

You can download the files on the NES Toploader project page and check out the progress of the portable.

After a bunch of hacking and cutting of the board I got the electronics done. It has 5000mAh of 7.4V lithium power which will run the portable up to 10 hours. The 5″ PSone screen has been hacked to the bare minimum. I removed the 7805’s that power screen and ran the 5V rail off the switcher power supply I made to increase the efficiency. The PSone screen is LED modded as well.

When decided to use a separate sound amplifier as the PSone screen was to greedy on power and did not boost the volume enough. I am using a Sparkfun audio amp that uses the TPA2005D1. This is a very low power audio amp that reproduces sound very cleanly. It is a very efficient audio amp.

I designed the case in AutoDesk 123D which at the moment is free to download. The case will be 3D printed by my friend Chris Kraft.

Here is the prototype case right out of the 3D printer.

The prototype case with all the parts inside. I had to make some slight tweaks to the design. The updated 3D files can be downloaded below.

It turned out really nice. This is essentially the largest thing Chris can print on his 3D printer and it did a great job!

I finished the bottom completely. It has the slots and holes for the power switch, volume slider, headphone jack, and power adapter.

I am working on the logo for the front. Here is the idea so far.

Let me know if yall like it.
