@freemo did I mention it will be open source with everything online

@Co Even better.. the hardware too?

@freemo sure! I will be using an arduino uno and I will experiment with LCD displays and of course I will design the rest. Any recommendations for a cheapish lcd for the uno thats got a fair resolution (think TI-84 PLUS CE)

@Co Nice! Excited. Is it going to have a full CAS?

@freemo sorry im not sure what CAS stands for

@WreckageBrother @freemo AC-130 imbound

@Co Computer Algebra System... it is wha seperates a typical calculator (which tends to just do operations on numbers) to a more advanced one like the TI-89, where it can do symbolic manipulation (integration, solve for x, solve ODE, etc)

@freemo oh yeah thats on the wishlist not that it won't be a pain hand implementing it, but it should teach me a fair bit and thats why I'm doing this and to be a showoff(classic me). Also if you have the time or anyone else does when I start im going to post a link of the proj here and feel free to join in!

@Co I dont think a calculator would be all that useful without it... its also why i wouldnt go with an UNO.. a good calculator needs good processing power. Personally I'd throw a raspberry pi or other SBC in there and then use existing CAS libraries behind the scenes.

@freemo what language you reckon i should use but I will definitely take the suggestion so probably a low profile pi 2/3 if that

@Co Whatever language you are most comfortable with that has a CaS .. R is a shitty language to work in but it is meant for math stuff, so you may find it a good choice here. Python has a CaS library too.

@freemo definitely got to go with python, I have been self teaching myself algorithms and machine learning specifically with it (even if I am reading ISLR)

@Co python will probably work and be easy enough... numworks calculator has a python interpreter in it that is kinda cool.

I'd suggest you play with the python CaS libraries availible to you first before you get too far along just to make sure they will be a good solution.

@Co and no, off hand i cant think of a cheap LCD that is a good enough size.. im sure there are plenty and ive used some, just not sure what they were off hand. I need to check which one im using on my ROES project.. it is a little small but close.
