Handheld Foldable Cyberdeck (CyberPlug 3.0)

My cyberdeck journey started because I wanted to build a portable computer where I can connect electronic sensors and parts directly to the computer. The first 2 versions had issues that made them unpleasant to use, so I designed the third one (hopefully the last one). Parts and functionality:

• Raspberry Pi 4 powered by 5000mAh power bank
• Rii K06 keyboard
• 4" IPS touch screen
• Internal breadboard soldered directly to the GPIO pins
• Hinges and magnets (10x3mm) which allow using the cyberdeck as a desktop or portable computer

This version has some significant advantages compared to the first 2:

• Easy access to the Raspberry Pi and breadboards through the back panel to change pins if needed
• Much more comfortable to hold
• Doesn't need a stand to use on a desk
• Can easily connect a second monitor
• Keyboard and power bank are easily removable if I need them somewhere else
• On a desk, the cyberdeck is still usable even without the power bank and keyboard if removed
