UNTESTED just a basic interface plate for this cheapo screen https://www.aliexpress.com/item/QH86-1-44-Inch-1-44-Serial-SPI-Resolution-128X128-Driver-IC-ST7735S-True-Color-TFT/32803895039.html

you will need an 0805 resistor, normally about 10ohm

just watch the pin numbers on the screen!!!

Sinclair Scientific Calculator Emulator V5 - r6 - RC1 (FULLY TESTED)

By ArduinoEnigma

2 layer board of 1.98 x 3.94 inches (50.2 x 100.1 mm).
Shared on April 11th, 2018 01:17

A very accurate emulator. This version has a keyboard and display circuit that is the same as the original calculator, download SinclairScientific5 from github to make it work.

Uses an Arduino Nano or clone.

RKO/RKN are 4.7K, this is just a path to ground for the ADC.
R1..8 are 1K, smaller resistors makes it brighter

Buttons are standard 6x6x5mm.
You can also use 6x6x4.3mm to make the keys a little harder to push, like the original calculator.
For more accuracy, use blue for numbers and white for everything else.

Uses 3 displays type: 2352B / 2352BS
https://www.aliexpress.com/wholesale?SearchText=0.25"+RED+7+Segment+display+3+Bit

Power Switch is:
https://www.aliexpress.com/wholesale?SearchText=L8.5*W3.5MM+3P+2T+Mini+Toggle+%2F+Slide+3mm

Power comes from a 4 AAA battery holder attached with double sided sticky tape to the back of the keyboard, The width of the holder should be 50mm or less

4 M2 hexagonal standoffs keep it off the table.

The Trump

By AverageMaker

2 layer board of 2.57 x 2.21 inches (65.2 x 56.1 mm).
Shared on April 10th, 2018 19:56

A comical add-on board for the Raspberry Pi. Once assembled with LEDs, resistors and a switch, you can program the second LED to light up whenever the American President sends a tweet (like a warning to the world). If you’d rather not know, use the switch to turn off the script (with the 2nd LED as a script on/off indication light). “Make PCBs great again!”.

More details, BOM and some example code here: http://averagemaker.com/2018/04/the-trump.html
