This will have 3 parts: 1 is now completed, part two will cover the power management system + battery and 3 - joysticks. I structured my workflow like this because back then, honestly i had no ideea how all this should came together , i had no ideea how a power management system intimately worked , just had my (poor) programming skills ,basic understanding of electronics(still not improved much here
) and a burning desire of getting things done driven by actual cold hunger (for food ,not higher meaning etc) For f's sake, i didn't know how a FET worked , i had to learn this the paesant's way , googling "acts like an electronic switch" so this will make a better picture of how clueless i was
So, i designed the case (forgot - the case should by the same lenght as a wiimote- this was a challenge in itself , ended up missing one mm , i had to redesign it many times for that stuff to fit) -in the end turned up ok...ish
Here it is with a wiimote next to it ,now you know where i'm going with the concept:
Then, with the case ready, i started working on the battery. All i knew was i had to fit all these in the case\s dimensions:
Researched the Fet's, sourced one, basically now all i had was to program a Arduino to output 5v to controll the supply via the FET
Along the way,the program was getting bigger and bigger , now the battery could show the voltage, display a graphic bar , show the remaining play time, percentage,elapsed time and also got service functions like setting up the capacity(for correct calculations,should the battery cells should be replaced with different capacity ones), voltage cut-off for safety or improved game-time and sound on -off.All this was shown on a OLED display and controlled by a simple switch ,including Power On/Off. Satisfied and surprised a little too, i pet myself on the back, offered the same person a 6 pack an drank myselt into oblivion that same night. I was now at aprox 500 lines of code, this was shaping into a real operating system so i called it unapologetically A.N.O.S. (Absolutelly No Operating System)
As my A.N.O.S. was getting bigger
, also got his own voice thanks to a speaker i added for presses confirmation and also low-battery alarm
As it is now, it only alarms you on the remaining time page , at 10min left of power but maybe i'll change that , to warn on all modes, will see.
Well, good luck to me fitting all + 2 lipo cells on a 6mms thick enclosure!
Oh, thank you so much sir , it did! :
And that was the last sane thought i had, after that it all gone haywire.... stay tuned
