This project has been adapted from an experiment by John Ridley Stroop, who published his work in 1935. Basically it is a “trick.” It is a trick in that you are required to answer a question at a “second level of thinking.” In our test we have three tri-coloured LEDs and below each is a […]

The ADIS16488 iSensor® MEMS IMU is a complete inertial system that includes a triaxis gyroscope, a triaxis accelerometer, triaxis magnetometer and pressure sensor. Each inertial sensor in the ADIS16488 combines industry-leading iMEMS® technology with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, and linear acceleration (gyroscope bias). […]

Description The MAX1720x/MAX1721x are ultra-low power stand-alone fuel gauge ICs that implement the Maxim ModelGauge™ m5 algorithm without requiring host interaction for configuration. This feature makes the MAX1720x/MAX1721x excellent pack-side fuel gauges. The MAX17201/MAX17211 monitor a single cell pack. The MAX17205/MAX17215 monitor and balance a 2S or 3S pack or monitor a multiple-series cell pack. […]

The MCP6N11 single instrumentation amplifier is optimized for single-supply operation with rail-to-rail input and output performance. Two external resistors set the gain, minimizing gain error and drift over temperature. The supply voltage range of 1.8V to 5.5V is low enough to support many portable applications. All devices are fully specified from -40 to +125C. Features […]

A few months ago I wrote a blog post about the chipKIT Basic I/O Shield and used Analog RBG Strips to demonstrate the the open drain FETs. This post is to give details on how to wire up the strip LEDs to the I/O Shield. You should already know how to program MPIDE before using […]

The ADE7816 is a highly accurate, multichannel metering device that is capable of measuring one voltage channel and up to six current channels. It measures line voltage and current and calculates active and reactive energy, as well as instantaneous rms voltage and current. The device incorporates seven sigma-delta (Σ-Δ) ADCs with a high accuracy energy […]

Designing a DC/DC converter that only consumes micro amps of current at no load can be compared to fueling a muscle car with lighter fluid – you may get it to work, but it won’t be easy. High efficiency at full load currents is commonplace in most modern DC/DC converters; however, achieving high efficiency when […]

Introduction This program is a simple combination lock that I designed for an old Sentry® fire safe that was given to me without any lock electronics. I created a front panel with a keyboard and microprocessor with a six-digit combination sequence. Details The LED flashes to show it’s alive after power is applied. The lock […]
