 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Build a "programmable calculator" ;-) Everything it does: connecting a RP2040-LCD with a keypad. Programming is up to you!

I like it. :) They don't come much more programmable than that. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

+1 Add a IR LED and/or RF module and you have a customizable remote control for multiple devices. Could be very handy. |

Add a BT module then you can use your phone as the keyboard. Erm, but there's already a calculator on my phone... :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Good ideas! The box is large enough to build in all these ideas. My primary reason to setup this calculator is the game "Hare and Hedgehog – Game of the Year 1979". There you have to calculate the number of carrots to move from a starting field to a destination field. Even better would be a calculator which tells you how far you can reach within 2 or 3 or 4 rounds or what will be the "best move" to reach the final destination as quickly as possible. So I will use it as a "carrot-calculator" & "gaming-advisor"  -andreas |

I wasn't entirely serious about the BT.... :) However, after further consideration, it might then be possible to use it as a numeric pad. A JDY-40 controlled by 7 or 8 GPIO pins could control another one connected to relays or something. Some fancy soldering on little connections though!

Maybe have a look at the Elektor kit |

34 quid +carriage +VAT and it's inferior as it's Pico-free! :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
