I’ve been having some problems configuring the optimal fan speeds on my computer. Part of the issue is that I have no way of seeing temperature changes while I’m using full-screen applications. A little help from Wolfram, a Raspberry Pi and Adafruit’s LCDPiPlate got me the information I needed.
I wanted to see if it would be possible to create a makeshift remote sensing device using Wolfram on the Raspberry Pi. Toss in VNC and some earlier code that I’ve written and here’s what I came up with.
I finished off the year right, with a limited edition Goose Island Stout.
I received an Arduino Uno for Christmas this year, so my Dad and I spent some of the holiday time doing some projects. His job was to get a circuit built implementing a 74HC595 Shift Register and my task was to set up some RF communication. Dad completed his project before I did, but as I’m on vacation all this week, I was able to finally get something up and running.
Just a short message to announce that I am working on a voice recognition system for the Raspberry Pi that has less overhead than some of the currently available options. More can be found in the Readme file of the github repository and I’ll be updating this system over the next few days.
Quite a while back, I used Jasper to create a speech recognition periodic table fun fact program. That was before my website was revamped and I lost the original blog post. (Well, I do have it in my backups, but it’s not really worth reviving at this point.) I do have a video showing the results, however:
I’ve started to revisit this project, and here are my first thoughts…
I’m no longer going to use the phrase like getting water from a stone, because it is probably easier than getting sound from a Raspberry Pi! Here’s some notes on how I’ve coaxed a few notes out of my Pi.
Is it time for you to do a science fair project? Are you looking for ideas? You’ve come to the right place.
As one of my ‘loyal readers’ has pointed out (thanks Nick), the schematic in the MagPi has the LED in the wrong way. Be sure to connect the negative side of the LED to Ground and the positive side to GPIO25.
Wolfspec 2.0 – Spectrometry with the Raspicam
This post is a reprint of an article I wrote on my earlier website. I’ve tried to update the links and images, but may have missed a few.
I recently purchased the camera that attaches to a Raspberry Pi and thought about how one might be able to make a spectrophotometer using the camera as a ccd-like detector. This work is still in progress, but with relatively few steps, I was able to get an instrument up and running (and even calibrated – sort of).
