Maker and classic calculator fanatic Alex Garza has launched a equipment to construct an emulator of Hewlett-Packard’s basic HP-15C and HP-16C calculators — software-selectable, and each working atop a Microchip AVR128DA microcontroller: the PX-VOY.
“The PX-VOY is a DIY calculator equipment that faithfully emulates the enduring HP-15C and HP-16C,” Garza explains. “Each high and backside panels are reversible: one aspect labeled for the 15C, the opposite for the 16C. Embark on a enjoyable and academic expertise by constructing your individual calculator. Superb for electronics fans and followers of basic HP calculators, the PX-VOY presents each a rewarding mission and a strong device.”

Garza first demonstrated the equipment earlier this yr on the Museum of HP Calculators discussion board, the place followers of the HP-15C and HP-16C — the previous HP’s first so as to add assist for advanced numbers and matrix calculations, the latter geared toward programmers with assist for hexadecimal, decimal, octal, and binary representations with a phrase measurement configurable from one to 64 bits — expressed their admiration for the design. Like Garza’s earlier kits, the entrance panel is a PCB that makes use of copper and silkscreen layers for labeling soft-touch keys which poke by means of cutouts — with a bigger cutout for the show, a low-power monochrome LCD with a 250×122 decision.
The brand new design upgrades on its predecessors, although, with a shift to the extra highly effective Microchip AVR128DA microcontroller — “quicker,” Garza explains, “extra storage, and nonetheless eight-bit” — and features a serial port for communication with a desktop machine. “The [serial] format is appropriate with the SwissMicros internet decoder/encoder,” the maker notes, “and must also work with Pierre’s Excel decoder/encoder.”
The PX-VOY is obtainable to order on Garza’s Tindie retailer, priced at $99.99 as a equipment of elements or $124.99 totally assembled. Extra info is obtainable within the mission’s thread on the Museum of HP Calculators discussion board.
