FPGA /Raspberry

The Raspberry Pi and other 'tiny computers' are really great! But an FPGA is best!

This is a nice example.. because it's kinda Open-Source.

Ternary/Analog Computers

I'm a huge fan of ternary and analog computers.
... They feel like a step toward quantum computing!

While binary logic has dominated computing for decades, I’m fascinated by analog and ternary systems. By moving beyond simple 'on/off' states—whether through continuous signals or three-valued logic (trits)—these architectures bridge the gap toward quantum computing. They offer a glimpse into a future where information density and processing efficiency are no longer bound by two-state constraints.

And, as far as I know, these can easily be implemented using a FPGA.
