We’re almost done with this stage of the project! (I think…). Admittedly, this part has taken me longer than I initially anticipated, mainly because I wanted to spend a bit of time trying to figure out what the heck was going on with the circuit (circuit analysis isn’t exactly one of my strong points…yet)

For the next few posts, we will be going into the nitty gritty details of the conditioning circuit. I want to spend lots of time at this stage for two reasons:
- Analog circuits and analysis have never been my strong points and this is a great way to change that
- The last thing we want, is to work with erroneous data caused by poor design of the conditioning circuit
Today, we will be briefly looking at the circuit and focusing on its behaviour.
What you see above is the first breath of the seismometer – which is currently detecting my foot taps.
Welcome to part one of the Seismic Sundays series! For the next 3 to 6 months, I’ll be attempting to make a seismology station that sends data to a web server for anyone to see. Today’s post won’t have anything technical on it. I will just be talking about what I plan on doing.
I’m really interested in aviation and lately, I’ve been toying with the idea of making a glass cockpit. This is a big project and most of my time will probably be spent on it. There are a lot of different systems for the glass cockpit like an IMU, an MCU to take in sensor data, a display for showing information and much more.
I’m starting off the project by working on understanding GPS. I’ve managed to make my own (albeit bulky) GPS receiver that shows coordinates, speed, altitude and heading:
Things have been busy.
The Sound Revolver (SR) was accepted to make an appearance at the Vancouver Mini Maker Faire but before I went there, I thought I would do a couple of things. One, go to Calgary to visit an old friend and fix his Nintendo and two, visit a class of grade 3/4 kids and talk about the SR.
A little while ago, I added a couple of new “firsts” to my lists. One was buying something from Etsy and the other was finally buying something from Adafruit. I bought a messenger bag from CrawlSpace Studios through Etsy and I decided that having just a bag would be a bit boring, so why not add some electronics to it?
Notice: The Sound Revolver (Augmented Music Maker) now has its own project page which you can find here!
I have mentioned before that I am really interested in musical interfaces. I have also been working with openCV a lot lately and (naturally) I wanted to merge the two concepts together. A while ago, I came across the reactable, a really neat synthesizer that makes use of blocks you place on a special table top to create sounds. I really loved that idea of augmentation and I wanted to make something similar.
I haven’t come up with a name for this project yet so I’ll use AMM (Augmented Music Maker) as a placeholder name for now.
Edit: Thanks to a wonderful class of grade 3/4 students, the official name for AMM is now “The Sound Revolver.”
The Freshest Instru-mint Whistle (FIW) is a proof of concept for a project I had in mind for a while as well as the opportunity to do something useful with the PIC32 Starter Kit I bought earlier. I did a blog post of my thoughts on the starter kit earlier found here
Merry Christmas everyone!
For the holiday season, I bring to you a project where I have some fun with a stuffed toy robot and openFrameworks.
