Replace a rotary

Replace a rotary switch with a potentiometer

Microcontroller-based products sometimes require rotary switches. As many microcontrollers have an onboard ADC, it is easy to replace the rotary switch with a low cost potentiometer, when a rotary switch is too expensive or unavailable. Although digitizing a potentiometer setting to act like a switch requires only a few instructions, an immediate problem is that

MAKERLISP MACHINE – AN EXPANDABLE EZ80 CPU CARD RUNNING BARE-METAL LISP

Classic computing on modern hardware: an expandable eZ80 CPU card running bare-metal Lisp. The MakerLisp machine is a portable, modular computer system, designed to recapture the feel of classic computing, with modern hardware. The machine centers on a 2” x 3.5” business card-sized CPU, which can be used stand-alone, or plugged in to a 2”

Use a Momentary or Tactile Switch as a Pushbutton Switch

Just a Moment Tactile switches (a specific type of momentary switch) are everywhere and they are especially popular on DIY  electronics and microcontroller boards because they are well suited to act as a boot option or reset switch.  Particularly, momentary switches are switches that don’t save their state when you depress the switch.  That is,

MINATURE OPTICAL GYROSCOPE IS SMALLER THAN A GRAIN OF RICE

MINATURE OPTICAL GYROSCOPE IS SMALLER THAN A GRAIN OF RICE

Gyroscopes are present in virtually any modern electronic gadget. They re used in a host of techs, like cell phones, vehicles, drones and wearables. The gyroscopes used presently in our phones will most likely be MEMS-based. Caltech, has gone some extra miles, by successfully developing a new type of gyroscope that is 500 times smaller and 30
