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 first lessons I learned in consumer electronics is that version 1.0 is the “can we?” release. Version 2.0 is effectively a do-over of 1.0, where we fix all the obvious problems we didn’t fix and the new obvious problems we didn’t predict. Design school has their own version that boils down to […]
A few years ago when buying Moogfest tickets, I noticed that in addition to the “VIP” ticket option there was another choice, “Engineering/VIP”. Not only do you get VIP status, you get to do something nerdy and take home hardware so *of course* I go for that upgrade. The project turned out to be assembling […]
A few months ago, while teaching in the Spring, I applied for a F/T position at CMU HCII working on a research project and signed a 1-year contract. However, I’m writing lots of code at work and by the end of the day I really haven’t felt like working on warifuru. I’m learning caffe, openpose, […]
