Ah.  OK, well, that is certainly doable, though how small you can make it is ultimately limited by the size of the display.  How small do you want it, and how much are you willing to pay?

Please keep in mind that the current SC4-HSM is just a proof-of-concept prototype developed on a shoestring budget.  It’s more of an Apple-I than a Mac.  But you have to start somewhere.

Here’s a photo of an earlier version of the HSM using a seven-segment display instead of the current 128x32 pixel OLED, next to the current version for size comparison:



Is that small enough for you?
