Wolfram’s Mathematica can run on a $5 Raspberry Pi zero. While it may be painfully slow, it does open up opportunities to use Mathematica in low-power, remote-sensing applications. This blog post is a first in a series highlighting the design challenges I’ve encountered (and in some cases overcome) building Mathematica on Pi (MoP) devices. (Hey, I think I just created a new acronym.)
This is a short post to show off my first attempt at PCB milling. I’m a member of the Chicago Innovation Exchange. Well, I was, but now it’s no longer CIE but the Polsky Center, or maybe the Polsky Echange North, I’m not sure, but that’s what happens when someone invests $35 million in your incubator; you change your name. The center provides me access to a pretty swanky fab lab equipped with (among other things) an X-carve CNC mill. I recently completed my training on the machine and I wanted to put my skills to the test.
I’m late to the game, but I bet I’m not the only one. It turns out that there’s a very easy way to set up your old (version B, and presumably version A) Raspberry Pi as an FM radio transmitter. Here’s how I did it and what I used it for.
Do you ever wake up too early and can’t get back to sleep, so you decide to mess around with your Raspberry Pi, only to find out that the SD card has been baked and the operating system doesn’t load? This seems to happen to me more often than I’d like (both the waking up early and the baked RPi). There must have been something in that instant coffee (didn’t want to wake my wife with the noise of the coffee machine) and Italian Sweet Creme flavored creamer (instant coffee tastes awful without it) because I was able to come up with a reasonably clever solution to my problem this time.
I’ve been a little quiet lately; some of that was end of the semester and family activities, but part of it was that I’ve been trying to put the finishing touches on a new project. I now think that OMIS – the open millifluidic inquiry system, is ready for display.
