The HP-01 wrist instrument looked like a digital watch but was smarter than many pocket calculators. It performed more than three dozen functions to manipulate and interrelate time, calendar and numeric data. With six interactive functions (time, alarm, timer/stopwatch, date/calendar, calculator and memory) the HP-01 had 28 tiny keys that the user operated with a stylus built into the bracelet.
The HP-01, code-named “Cricket,” was not a successful product for HP. It was too bulky and heavy, and HP sold it though upscale jewelry stores. But miniaturizing the math functions was quite an engineering feat, and when HP discontinued manufacturing the HP-01, its inner workings were destroyed so no one would copy the extraordinarily small package engineering. The HP Archives has a few of the remaining elements.
The HP-01 currently is one of the most sought after collectibles in the antique electronics market, often fetching two or three times its original price ($650 for the silver color, $750 for the gold version).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
