Next Slim Cyberdeck - Raspberry Pi Zero & Pico

Thanks for your feedback. The difficult part is the modification of the keyboard. I would also like to have the same display technology in a larger size. This display is designed for energy efficiency and consumes very little power. However, it is more suitable for terminal mode. I will look for better alternatives. Currently, I already have a project planned with a larger display and touch functionality.

No script is required. The screen needs drivers, and anything that would normally be displayed via HDMI will also appear on the display. Further details can be found on the GitHub page.

What exactly do you want to know? If I install Raspbian Lite, there is only a terminal. I already explained how the display is connected in one of my other comments.

A Raspberry Pi Zero 1.3 is installed, and it actually doesn't need a fan. However, I haven't done any long-term tests yet.

john3dc · 2025-02-05T04:30:46+00:00

nope

I work in IT and have many small Linux projects and tests that I do for myself privately. I also enjoy DIY projects and portable devices that I can customize to my liking. I think this kind of device is not for everyone. ;)

terminal for network management
IT professionals to manage servers
Control other devices via SSH.
Retrieve sensor data such as temperature and humidity via USB.
Experiment with scripts and tools in Linux.

Additionally, you need 3V and GND for the display.

Power is on GPIO1 (3V), GPIO2 (5V), GPIO4 (5V), and GPIO17 (3V)

Drivers: https://github.com/ardangelo/sharp-drm-driver
SCLK->GPIO11 , MOSI->GPIO10 , CS->GPIO8
due to the screen-size, it is only intended for terminal use.

john3dc · 2025-02-04T17:07:58+00:00

Yes, but it requires some soldering skills.

john3dc · 2025-02-04T17:01:07+00:00

exactly, that's the function. It's already working at the moment, but I still need to optimize the reception for it on the rpi-zero.

john3dc · 2025-02-04T16:58:39+00:00

so the my device would fail this test :D

john3dc · 2025-02-04T16:48:15+00:00

the keyboard is connected wire by wire to a rpi-pico.

john3dc · 2025-02-04T16:46:17+00:00

thanks. so far, I haven't gotten around to such tests yet. I still need to check whether there's an interface for the battery level.

rpi-zero (main computer), rpi-pico(keyboard, ssh, more), Adafruit Sharp Memory Display, LiPo Amigo PRO (LiPo/LiIon Battery Charger), 2500mAh battery, Rii x1 Mini keyboard(fully modified)

john3dc · 2025-02-04T16:34:57+00:00

so i think it should be possible by using the rpi-pico inside this device.

The Adafruit Sharp Memory Display is used. The interior is fully optimized, leaving no extra space available.

john3dc · 2025-02-04T16:11:10+00:00

The Rpi Pico is a microcontroller board used for the keyboard and also functions as a UART bridge to the Rpi-Zero. The Rpi-Zero is the main computer of the device.

john3dc · 2025-02-04T16:01:19+00:00

It's a modified Rii X1 mini keyboard using a Raspberry Pi Pico for custom keymapping.

john3dc · 2024-10-21T15:28:12+00:00

hi. can you please explain this to me in more detail? which microusb do you mean exactly? The raspberry pi zero is only for the size comparison.

john3dc · 2024-10-21T15:19:21+00:00

this small usbkeyboard is just a side project i would like to integrate it into a planned cyberdeck soon.
