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.
There are a number of websites out there that take advantage of the lens of a low-end laser pointer, using it as a macro lens for phone cameras and such. None that I found, however, mentioned that the lens is just the right size to fit inside a Lego...
It's been a while since I've been inspired to make some cupcakes. My wife reminded me that I had a nice holiday table display for cupcakes so I decided to give it a go.
In part 2 of this series, I demonstrated the basic use of custom defined characters. Now I want to exploit the custom characters to make a fully customized display. It isn't going to be easy because we've got 8 custom characters and 32 character spaces to fill. In the end, we see the limitations of this setup (or more precisely, the limitations of me writing the code for this setup), but hopefully end up with some useful tools.
This year, I spent a lot of time combining one of my favorite childhood toys (Legos) with science and electronics. To commemorate, I decided to build a Lego Christmas village filled with blinking and flashing LEDs. My wife added a little bit of a twist by getting me the Lego Star Wars advent calendar, so the holiday scene became an eclectic mix of toys, science fiction, and electronics. Oh and I threw a Raspberry Pi in there for background music.
The Raspberry Pi (model B) has only 2 USB ports, which makes connecting a mouse, keyboard and WiFi dongle challenging. In the end, many folks go for the powered USB hub solution, but I find that there are times I want to slim down the wires and components that I'm carrying, and I'm always carrying my iPod touch, so why not take advantage of that?
Back in the day when we didn't have mobile devices to occupy our time on the trip to our family vacation destination, we had to entertain ourselves with pen and paper. I liked Mad Libs back then, and have recently been thinking about how we can use the same idea to teach kids about science projects.
In part 1 of this series I showed how one can create some basic functions to direct text output from Mathematica to an LCD display attached to a Raspberry Pi. In this part of the series I will focus on building custom characters. Before that, however, I'd like to take a brief look at how the functions in lcdlink behave when incorporated into Mathematica's dynamic features.
I'm interested in determining some of the specifications of my home-made digital microscope. I got a hold of a microscope reference slide and thought that I'd use a little bit of Mathematica to learn something about my instrument.
