USB-C powered 8"display for the Apple IIc with STL files and build plan

[ArjenCNX]

​

Hi there everyone,

Recently i have spend some time to make a 3D printable display for the Apple IIc, and today is the day to share the design as all is finished, assembled, tested and so on.

I am sharing the STL files so you can print the design yourself (or send it to a printing company) and a simple guide on how to assemble it.

The Display used is a 8" Eyoyo screen with an IPS panel that performs well, is bright and has lots of contrast. its also very cheap, so affordable for most people.

Provided are:

- STL files for all parts
- assembly guide
- parts list

Parts used:

• Eyoyo 8” LCD monitor S801H for the LCD display and the driver
• Generic USB-C PD sink PCB (https://www.amazon.sg/Trigger-Module-Charge-Charger-Delivery/dp/B0BY8H5MS1)
• RCA cable with minimally 20CM cable
• 2 strands of standard electrical cable ( Red+Black)
• 2 hex keys 3mm (need to be cut to size)
• 8X M3 12mm screw
• 2X M2 screws 15mm
• 2X M4 screws hex head 40mm
• Inserts melt-in type M3 2X 10mm
• Inserts melt-in type M4 2X 10mm
• Inserts melt-in type M2 2X 10mm
• Filament Polar filament PLA retro platinum PLA or equivalent
• Spacers nylon 20mm diameter M4 hole 1mm thick (needed to hold the display and as thrust bearing)
• Double sided tape (the foam type, ideally 3M)

If you need any guidance, or you want to share improvements, please ask/add/create!

I hope someone will enjoy this design, it was fun to make! This will allow, in combination with a USB-C power adapter for the IIc to run the whole set off a single power bank (provided it supports USB-C PD) power consumption is around 4W for the display, and 8.5W for the computer (+7W when the disk drive runs)

Nice! Did you happen to note what actual lcd panel the Eyoyo display uses? I've been eyeing that one too for a color SE/30 project as the HJ080IA-01E I bought is a bit too dim for my taste.

Let me check, Unfortunately there are no markings on the screen, but in my experience its quite bright, i don't have the tools to measure it but by looking at it i would estimate it to be about 350 nits or so. If you don't like the brightness of your current panel, there are some things you can do, you could check the LED driver and replace the current sense resistor with a slightly lower value to increase output (consult the LED driver datasheet to select the correct value/resistor) and i have done upgrades in the past with generic backlight LED strips, this works wonders for laptop displays that still rock the old CCFL tubes, you can double the brightness without too much fuss and lower power consumption.

I actually looked into replacing the resistor, but I couldn’t even manage to figure out which on to change on the driver board (pcb800099) . I got ahold of the panel spec sheets so know what the backlight wants for full light. It should be 300 nits, but juding how dim it is I really don’t think it’s driven right.

This is neat. Is the rotating part attaching to the base compatible with the IIc Monitor Stand? That would be even better

This is a very nice design and nicely executed. Well done!

the stand snaps in place with the grooves on the top of the Apple IIc, so it cannot slide around but is also not fully clamped by it, making sure i don't damage the sometimes fragile plastics of the casing. (but im not 100% sure if that answered your question) i never had the LCD display for this unit.

Thank you Sir!

No, my question was whether it's mountable on this original stand for the original CRT

Ah, that's right!~ i forgot about that one i didn't make it for this, i doubt it will fit, the mid-section of the LCD bevel hinge is 140mm wide, i suspect this is wider then the CRT hinge. potentially quite easy to adapt though (if someone wants to do this, just let me know)
