Wow! I like the µCalc design very much.
But I really miss a piezo for the key click. Click not beep! I hate beeping keys.
If I use a calc the keyboard feedback is important for fast and secure usage. I am a long time HP48SX user.
I think there is enough room for a small piezo.
If you sometimes think of selling the µCalc I would prefer to buy a DIY kit with pcbs and parts.
Thank's for your always inspiring EEVblog!
