Hello all!
I proudly present IV and IV7 - probably the best RPN calculators I have built so far.
They are based on arduino hardware (avr atmel328) and are programmable (900 steps, FORTH-like).
While IV has an OLED-display IV7 tries to represent numbers and text (yes that's somehow possible) on an 8-digit-7-segment-display.
