Open Wave Height Logger
OWHL – The Open Wave Height Logger OWHL is a project originally dreamed up by Jarrett Byrnes and Ted Lyman at UMass Boston. Early on they contacted me for my thoughts on how to accomplish the goal of making a cheap, long-life pressure sensor data logger that could be used to record ocean wave heights…

Arduino code for MS5803 pressure sensors
I have recently been developing a library for the Measurement Specialties MS5803 line of digital pressure sensors. These sensors are available in several different pressure ranges from 1 to 30 bar, they are submersible if installed in a proper housing, they communicate via I2C or SPI, and they cost around US$35. It’s fairly straightforward to…

ATtiny84 LED display and heater project
Here’s a little project that uses an ATtiny84 microcontroller, programmed with the Arduino software, to build a thermostatically-controlled heater. It allows the user to choose a temperature setpoint, and then displays the current temperature using an Adafruit 4-digit 7-segment LED display over I2C. The youtube video below demonstrates part of the project, where an ATtiny84…

Using Arduino tide predictions
In the previous post, I outlined some Arduino code to generate tide height predictions for a NOAA tidal reference station. Now let’s do something useful with this newfound functionality. In the experiments I run, it’s useful to keep intertidal animals like snails and limpets on a natural tidal cycle. In addition, some animals like high-shore…

Tide height prediction with the Arduino
A collaborator of mine, Dr. Jeremy Long at SDSU, approached me with the idea of building a system to recreate rising and falling tide heights in his aquaria. One of the keys to making this work was having some way to specify what the tide height should be at any given time. While there is…

BBQ controller, version 2
I have recently started using an Arduino microcontroller setup to control the temperature in my electric BBQ smoker. It displays the air temperature and three meat temperatures on an LCD screen, while the temperatures can also be viewed over my home wireless network.

Book Review: Practical Computing For Biologists
The book Practical Computing for Biologists aims to teach you all of those little tidbits about using computers that they never find the time to expose you to in graduate school.
