Installed a couple of particle detectors that count particle sizes of 1.0, 2.5, and 10.0 microns. Looking at these values along side CO2 and tVOC in the kitchen is one functional test. Last night I used Alton Brown’s “Election Night Steak” recipe, and on the printed copy I’ve written “only cook in summer” because of […]
For the past few weeks I’ve had sensors in my studio (2nd floor) and kitchen (first floor) and data collection has been interesting. Some things I’ve learned looking at the data I’ve collected. I’ll post some images to illustrate these in the future, but just wanted to share my notes with other people. The best […]
Digging through sensors I already have, I discovered that my Sparkfun Qwiic Ideation Kit came with an Environmental Combo sensor that can detect temperature, humidity, CO (carbon monoxide), and VOC (volatile organic compounds). The list of VOCs is long but NO2 is in the list. What’s Qwiic? It is a standard from Sparkfun for I2C […]
Let’s start by saying the thing nobody who loves cooking wants to hear: Gas stoves are bad for the environment and for humans in the kitchen and we should stop using them. Yes, I know they are magic tools for controlling fire. For decades I’ve passed on renting an apartment or a house simply because […]
Starting a new category because I’m starting a new project and it needs a home. For several years I’ve been teaching “Making Things Interactive” at CMU’s IDeATe program with all assignments turned in on the class blog. It’s basically “Arduino 102” where we take what people learned in an intro to physical computing class and […]
It’s that time! As I did in previous classes, I’m posting all my notes and students are posting all their assignments to the class blog.
One of the main features of warifuru is a set of tools to help people who use laser cutters for their job. Tools like optimizing layout for the fastest cuts (aka 2d bin-fitting) or patterns that determine the best power/speed for etching a given media by making a big-ass etch grid. Then I found deepnest […]
