To get those thin tactile buttons align w/ the original keys may be tricky. (09-22-2014 02:14 PM)hp41cx Wrote: Great!! Price ? Production ? This is a hobby project w/o production in mind. I am more of a electronic hobbyist than a calculator expert. There could be another 1-2 iteration of PCB cycles to perfect the design. So you are looking at at least a couple of months before I can make extra builds. I had made this other TI DataMath calculator which is similar, we (from a MCU forum 43oh.com) did a group buy project (kits) and the cost of components is about US$20, for the HP-25C, it should cost may be 50% more as the led bubble displays are costly (we need 3 sets for 12 digits) and the microcontroller also costs more. http://forum.43oh.com/topic/5537-group-b...e-display/ I am new to the forum so please let me know if it's not appropriate to post external content, etc. |
