This is it.
Up until now the only people who were able to see data coming out of the seisMeowmeter was myself and anyone else I showed it to. Today, all that changes. Now you too, can see a stream of seismic data in the Calgary area!

Seismic Sundays 6 – We Have Data!
So between having to deal with an insane work schedule and fighting with an unruly microcontroller, I’ve managed to finally digitize the output of the seismometer:
Seismic Sundays 5 – Fail
Take a look at these two waveforms pulled from a UART line with a logic analyzer. Notice anything interesting?
Seismic Sundays 4 – Circuit Analysis
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)
Seismic Sundays 3 – Debugging Woes
First, I have to admit that I messed up building the conditioning circuit. The first RC network after the first op-amp stage should have had a 6.8kΩ resistor. I accidentally used a 68kΩ resistor instead.
Seismic Sundays 2 – Old Haunts and Bode Plots
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.
Seismic Sundays 0 – The Beginning
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.
