Frugal Glass v2

“One never notices what has been done; one can only see what remains to be done.” -Marie Curie

I must say it’s the case with Frugal Glass. I’m unimpressed with the performance of the current version–the eyepiece assembly is heavy enough to pull my glasses sideways, it blocks vision out of one of my eyes, […]

RTC Setup

One of the features I wanted to implement was the ability to keep time without a network connection. To do this, I needed a realtime clock. I found one at SparkFun that was flexible enough for my needs, based on the popular DS1307 chip.

After a bit of Google-probing I found another article […]

Jasper Modules, Part 1: Camera

Writing Jasper modules isn’t exactly fun. Jasper is an open-source interface for many speech-to-text and text-to-speech engines. It also provides a conversation interface. Jasper modules can be standard – which wait for the user to initiate contact – or notification – meaning they monitor a stream and report back every now and then. For instance, […]

Jasper & ALSA

I just spent the last day configuring Jasper with ALSA. Jasper is a suite of Speech-To-Text and Text-To-Speech engines with a nice(ish) end interface. ALSA is the Advanced Linux Sound Architecture, a utility for playing and recording .WAV files.

I was having issues with Jasper – it was throwing an IOError -9997 in one of […]

Video glasses & Pi: just add solder

I’ve been tinkering around with these video glasses from Adafruit. There is a cable inside that seemed to have exactly what I need – a cord that runs from the glasses’ 2.5mm TRRS jack to the Pi’s 3.5mm Composite Video TRRS jack. But when I plugged it in, the screen flashed for a […]

Project Week is here!

Time for Project Week! Project Week is an event at my school in which we students (and some teachers as well) take the second week (the week before Spring Break) of March off to take a deep dive into their interests. This is well planned out, sometimes starting in January, sometimes in November.

This year, […]

SparkFun: BadgerHacked

Every year, Austin (Texas) has an event for makers, tinkerers, and other nerds who like to build. It’s called SXSW Create. This year, I was manning a booth with The Robot Group. Sparkfun Electronics was giving away these little badges:

They gave you a bag of parts and […]


This piece of code was made possible by Trey German, Robert Wessels, and Cathy Wicks of Texas Instruments. Without Trey’s knowledge and Cathy’s encouragement, I wouldn’t have been able to make this program. Robert is the one who told me about this project.

When creating 430AlarmClock, I adhered to my usual […]
