Title: Custom Raspberry Pi 500, Rasp Pi 400 inspired-CODE NAME: GIZMO
Post by: JKnightandKARR on Jun 18, 2024, 08:43 PM
I want to make a custom ver of the Raspberry Pi 400, Raspberry Pi 500 unless I find a better name, only replacing the Raspberry Pi 4, 4Gb with a Raspberry 5, 8Gb, which I got the w/active cooling option.

I found an RGB keyboard, it's by RedDragon and it's the K556 RGB, I have a wired Steel Series mouse. I am going to put the Pi 5 into the middle of the case, and use 3 USB Ext cables and one Ethernet Ext cable, and a GPIO extender, most likely won't ever use that, but never know. I have an old aluminum full cookie sheet from work I am going to make the case out of, hopefully by cutting it out in 1 pc and just bending it. Also will add at least 2 sets of GPIO ports, 1 in case of a hat use and another if I need access to pins while using a hat.  I found a way to expand the GPIO port, GPIO Expander (https://tutorials-raspberrypi.com/expand-raspberry-pi-gpios-with-i2c-port-expander/)

  Right now, been figuring out the best material to make the base under the keyboard with.  Thought 3d printer, but would have to make in like 3 parts n glue together, also thinking of like sheets of thin balsa wood or other thin wood.  Then I need to make a quick PCB for the GPIOs, 2 ports, so can use hat in one, and still have unused pins accessed on other port.

I got a Red Dragon Devarajas keyboard https://redragonshop.com/products/devarajas-k556 from Micro Center for like $20, how good can it be right??...... downloaded software onto my desktop, and plugged it in to check the lighting options....... BIG MISTAKE!!!!! As NOW my Raspberry Pi 5 needs a new keyboard, cause I will be having WAY too much fun playing with the lighting, which includes effects like pushing a key and colored ripples go out to the edges of the keyboard! lol So going to look for options that will give me control of the RGB lighting from the keyboard or from Linux. lol

Edit: I just figured out that it HAS BOTH software and keyboard control of the LEDS! So going to get a 2nd one for it!

Well 2nd keyboard in hand, however, i am having issues taking it appart to move the cable, it it could, so will have to make keyboard slide into the case and have a small top at the very top, so a cable isn't sticking out just to go back inside. Will also use the 6 side holes for its screws to secure keyboard to the case, just need to get longer screws.

  Small update,  After looking at a video on the keyboard, there are 3 screws on each side, as well as several on top, which is why I couldn't remove the case, so I need to remove all the keys, and then I can disassemble it to relocate the cord, and fill that hole.  I can make the new case addition out of something and screw it to the bottoms before putting the top back on, so that helps alot.  Still thinking on what to make the case with...

How's this project coming along? I need to get the photos up for my R-Pi 5 Computer System (https://savagecircuits.com/r-pi-5-computer-system/). I also found the code for the Pass Counter Demo (https://savagecircuits.com/pass-counter-demo-bs2/), so I should be able to get that going. But, thought I would see where your project was at.  ;)

I know...being a newlywed, you've probably got other things on your mind right now.  ;D

Well, here is Ver 1 of the case.  So far all I've done is map out the case and raise up the keyboard 30mm to make plenty of room for inside airflow, which I need to figure out a plan for that...  Probably going to make the case longer to add stuff behind the very top row of keys for an RGB JKnight logo, GPIO ports, not sure what else.

No I had not even looked at anything Raspberry Pi since i got the 5. Interesting. Makes me want to rethink my design n add a built in monitor.

I've not done anything really, been busy with stuff, but I have been thinking about how I want to make it look and finally know how to take the keyboard apart to do whats needed..... just involves removing ALL of the keys..... lol As well as I got meterial to make the case, and a mock up case to check for fit.

Well, I have a decent idea what I want todo on this. It's been named Gizmo after my little buddy Gizmo, my sweet little Miniature Pinscher. I'm doing both images and links to images, as I've had issues with photos not working for who knows why.... I've colored it to make it easy to see everything.
(https://jknightandkarr.altervista.org/Computers/G1.png)
https://jknightandkarr.altervista.org/Computers/G1.png (https://jknightandkarr.altervista.org/Computers/G1.png)
In this image, the Gizmo and JKnight logos are going to be RGB LED, the keyboard will just drop into the top and will be held in place by 6 screws on the sides, and by ledges in the inside.  The keyboard RGBs can mostly be controlled from the keyboard using Fn+ arrow/6 keys above that.  Will have to see if Linux can use the drivers for full RGB control.  There's going to be 2 GPIO ports for using hats, and should access to pins be needed while using a hat or multiple hats, if access to them is needed, so far I can't locate anything to expand the GPIO port, so using ext cables and pin headers should something be found later for easy changing.

https://jknightandkarr.altervista.org/Computers/G2.png (https://jknightandkarr.altervista.org/Computers/G2.png)
On the back I've got access to all the normal ports, minus the PCIe, Cam/Disp 0/1 ports, which can be expanded later if I want to use them, I outta see if a MicroSD card extender is available to make access easy.


With this, adjustments can be made as needed, such as reset button, power switch, fan power supply, etc.  I'll add vents and some fans to aid cooling, as well as allow WIFI n Bluetooth access, as the body will mostly be metal.

There are microSD breakout boards, such as this one from Adafruit (https://www.adafruit.com/product/254), or this one from SparkFun (https://www.sparkfun.com/sparkfun-level-shifting-microsd-breakout.html). Admittedly, the SparkFun unit lacks any meaningful way to mount it, though they both provide level shifting. But I have seen these breakout boards used to relocate a microSD card to the back of an enclosure before.

The one I have, shown above, is by Redragon and is the Devarajas mechanical gaming keyboard.

I wouldn't even know how to use those since the Pi already has a built in card slot on the back. Maybe theres extension cables of some kind?

Well, the 2D plan of sorts is done, so I can lay out all the lines onto an old full-size cookie sheet from work. then just gotta cut out and bend. Probably have to learn brazing to hold it all together.

Round Panel Mount Micro SD Card Extender

Description

If you need to add a panel-mount connection that extends a micro SD card, this Round Panel Mount MicroSD Adapter Plug is the easiest and fastest way to panel-ify your project. The adapter is about 30mm in diameter, so you can drill a hole in your wood, plastic or metal with a common hole-saw or bit, no special shapes or filing required. Un-screw the plastic nut, insert the plug and re-attach. Ta-da! Now you have a microSD extension cable!

It's designed to easily attach to a panel up to 16mm thick (or 0.625"), or as thin as a few mm. Perfect for adding extra storage to your project enclosure! We like this plug in particular for its solid body and 'forgiving' plastic lip that hides the drill hole.

Please note: We did test this with a microSD card reader and it works very well but many devices use the mechanical removal of the card to detect when the media has changed. Since this extender end stays plugged in, there's no way for the host to know you swapped cards. What that means is that if you have an operating system where you cannot 'force' the rescanning of the SD card, it will not realize that its changed. This may be OK, especially if you're using it for, say, a boot SD for Raspberry Pi that you would shut down between swaps, or a 3D printer where you can tell it to reload or reboot.

The way I've seen it done is that the breakout board is mounted in the desired location, and wires from that board go back to solder pads where the original socket was. I know, it's a bit ambitious, but people do it.

If the CD line is used, that's where the breakout board has the only advantage.

3 pcs plastic vs trimming, bending, making holes, and brazing jobs...

Do you, at least, have a sheet metal break? Missing that would make things much more difficult. I have seen people make their own jury-rigged break, but that would be a bit difficult too.

Created a 3-part model for the case, I've got keyboard supports built in, and all parts are 3mm thick, not inc the 6mm thick supports.  I just have to lay out all the holes for cables, ports, and the upper text, which I have to try and figure out how todo.

Hmmm, that could do the job - never considered that before. It would seem to me that you'll need two pieces, one for the edge of the workbench (desk, table, etc.) and one for the top of the sheetmetal.

Great idea.

I wasn't sure what this question was in reference to. I looked back and may have missed it, but didn't see a reference to 3mm. So, why am I replying? Well, I did want to point out that all of the stock material I have for my laser cutter / engraver (basswood and acrylic) is 3mm stock. That all comes from xTool. The stock I use in my Acrylic LED Signs (https://savagecircuits.com/buffalo-bills-acrylic-led-sign/) is 2mm, which required me to construct a better shim for the bases.

P.S. - Most people I know use 5mm stock, which I don't have at the moment.

Just what I think might be best. Not too thin or thick.

Well, I did want to point out that all of the stock material I have for my laser cutter / engraver (basswood and acrylic) is 3mm stock. That all comes from xTool. The stock I use in my Acrylic LED Signs (https://savagecircuits.com/buffalo-bills-acrylic-led-sign/) is 2mm, which required me to construct a better shim for the bases.

P.S. - Most people I know use 5mm stock, which I don't have at the moment.
Thank you, this seems to confirm that Joe's guess is accurate - at least accurate enough for me to use as a starting point when I start designing my own cases.

So, 3mm to 5mm looks like a good starting thickness.

Quote from: granz on Aug 20, 2025, 12:49 PMWhere did you come up with the 3mm wall thickness? Is that a standard, or is it something that you came up with on your own? One of the things that I want to print is cases, and I'm trying to come up with measurements.
Just what I think might be best. Not too thin or thick.
Thanks. OK, that seems like a pretty good starting point for my experimenting.
I litterally just gave a quick thought and figured less then that be flimsy, and 5 might be too thick.

That's where your experience comes in - you just thought about it, and came up with (what seems to be) a pretty good guess.

Granted, 3D printed enclosures aren't quite as rigid as a injection-molded polystyrene or ABS case, but they seem quite solid to me. You may remember the ones I posted that have the LCD cutouts and mounts? They were ~3mm thick.

As for the 5mm stuff, the people I know that used that were building custom clear PC enclosures. I haven't talked to those people in many years, but for a short time, I was fascinated with the clear enclosures. Then I realized you could see all the dust (bunnies) over time. LOL

Ha, yeah, it's not normally a good idea to see dust bunnies inside a computer.

One client that I had, manufactured metal finishing products (think world's biggest sandpaper factory!) One of the computers, out on the manufacturing floor, needed work and I started to open it up. I immediately closed it back up, and took it outside along with a few cans of compressed air. The dust inside, covering the motherboard, was over half-an-inch thick. When I started blowing the dust out, several people came running to see where the fire was! :o

My computer repair horror story was from a customer that had dogs, cats and birds in her house. The PC / Desk sat right next to the bird cage. When I opened the case, the entire inside was crammed with hair and feathers. The CPU fan was completely clogged, as was the power supply. Disgusting!  :-[

Ugh! People can be pretty disgusting with their PCs.

Another job that I had (I was a database application developer, but was the only one who knew how to repair the things) I was walking through the office, and heard: hiss, hiss, hiss... I looked, and one of the girls had a hanging plant directly over her monitor (CRT.) She had just watered the plant, and it was dripping directly into her monitor!  :o

I grabbed the power cord for her monitor and unplugged the thing, and then explained to her that she was about to electrocute herself, or start a fire. She was suitably unnerved, so I took the plant, and moved it away from any electronics devices, and made her wait until the next day for her monitor to dry out.

On side note, are the leds on the ethernet ports connected directly to the data lines?? Not required, but was thinking of grabbing ethernet port off of old system, and wiring the leds up, just for status needs obviously.

On the finished case, it's going to take longer, having printer issues,, plus I gotta really think how to place everything inside, cables creating some issues. lol, and my resin printer isn't big enough to print my case, but It will somewhat be in a case.

Well Gizmo is feeling more done, I know its nothing more changed then a background, but it makes it look better. Picked the background, took photo of Gizmo, and removed everything else, layered him over and made the text using Photoshop tools.
