Apr 05 14:47:48 <HydraulicSheep> Hey Pac23. Just a quick update. I am currently disassembling a Casio fx 82
Apr 05 14:48:02 <HydraulicSheep> I have read some relevant documents about membrane keyboards
Apr 05 14:48:13 <HydraulicSheep> But would like to get more firsthand experience
Apr 05 14:48:23 <HydraulicSheep> I will post direct findings in the next few days
Apr 05 14:48:44 <HydraulicSheep> (regarding how to interface the keyboard with pocketbeagle)
Apr 05 14:49:21 <HydraulicSheep> In the meantime, this document (http://users.ece.utexas.edu/~valvano/metrowerks/Lab08d.pdf) discusses debouncing and interfacing with membrane keyboards
Apr 05 14:51:34 <HydraulicSheep> In prototyping, my process will likely involve soldering jumpers to the outputs of these buttons and connecting these to headers on the pocketbeagle
Apr 05 14:53:46 <HydraulicSheep> This will either require cannabilizing the existing PCB or buying a new PCB built to handle the rubber switches
Apr 05 14:54:29 <HydraulicSheep> If necessary, they are surprisingly affordable online (e.g. https://www.alibaba.com/product-detail/Custom-PCB-Membrane-Switch-Keyboards-With_60742775844.html?spm=a2700.7724857.normalList.61.15977afbkaOZ8O). I am able to bear this cost
Apr 05 14:55:16 <HydraulicSheep> But I will report back with further detail soon
Apr 05 15:58:54 <Pac23> i have tried cannibalizing the existing pcb but the way its integrated its difficult
Apr 05 15:59:26 <Pac23> i love your intiative though,do update the doc with the new findings
