The Raspberry Pi, and the WiPi USB dongle, with questions about power…

February 6, 2013 | My Projects, Raspberry Pi, Robotics | By: Mark VandeWettering

I’m having lots of fun with my Raspberry Pi, and I’ve decided to launch one of my crazy spare-time projects: inspired by this article detailing the construction of RUDEBOT, a kind of mobile tablet robot, I decided to build a robot of my own. But, anything worth doing is worth changing and adapting, so I […]

More OpenSCAD tinkering…

February 3, 2013 | My Projects, Robotics | By: Mark VandeWettering

The other day, I was at Harbor Freight, and picked up an inexpensive set of digital calipers. While goofing around, I decided to try to reproduce an object using OpenSCAD. I had just received a pair of motors from Pololu. They look like this: I sat in the editor, and set to work measuring. I […]

Tinkering with OpenSCAD…

February 2, 2013 | My Projects | By: Mark VandeWettering

It seems like I might have access to a 3D printer, so I thought it might be fun to see what I could design. I thought using OpenSCAD, a scripting based 3D modelling software that can generate models in STL, a fairly simple but flexible format that can be printed by lots of printers. I […]

What’s today’s Mayan Long Count date?

December 14, 2012 | My Projects | By: Mark VandeWettering

I wanted to know. I read up on the Mayan calendar. It was easy to code up in Python: Today is 12.19.19.17.13. In 7 days, the right most place will roll over, and the date will be 13.0.0.0.0, starting a new b’ak’tun. Or the world will end. Enjoy!

Some small experiments with Arduino sound…

November 29, 2012 | Arduino, My Projects | By: Mark VandeWettering

Last year, I spent a little bit of time to create a set of blinking Christmas lights that I could mount in a hat. It was powered by an ATtiny13 and mounted in an Altoids tin. While setting up my Christmas tree last weekend, I found them, and they still work. In case you missed […]

Simple code implementing the SmoothLifeL cellular automata…

Without further ado… if you want code to implement this: You can download this this zip file. Do with it what you will.

Crazy programming experiment of the evening…

October 11, 2012 | Computer Science, Games and Diversions, My Projects | By: Mark VandeWettering

I was struck by the lunatic programming muse again today. While reading my twitter feed, I encountered a description of SmoothLife, a generalization of Conway’s classic Game of Life. Instead of being implemented on a grid of discrete binary values, SmoothLife is implemented over a continuous, real valued field. What’s kind of neat is that […]

Making headway on the Axon…

September 16, 2012 | My Projects, Radio Controlled Airplanes | By: Mark VandeWettering

Earlier today, I tweeted: Okay, all major parts assembled.Now I just need the innards from Hobby King… twitter.com/brainwagon/sta… — Mark VandeWettering (@brainwagon) September 17, 2012 But I figured you guys might like some additional details. As I mentioned before, I decided to build a clone of the Axon, a nice light FPV platform designed by […]

Maiden Flights of my F-22 Foamie…

September 7, 2012 | My Projects, Radio Controlled Airplanes | By: Mark VandeWettering

Mark H. over at Eastbay RC and I finally got together to test out my first attempt at scratch building a radio controlled aircraft: an F-22 inspired “foamie”, which an aircraft constructed entirely from EPP foam, hot glue, a couple of short carbon fiber rods to stiffen, and hot glue. Did I mention the hot […]

It’s quiet… too quiet…

September 3, 2012 | My Projects, Radio Controlled Airplanes, Rants and Raves | By: Mark VandeWettering

I received my second email inquiry yesterday (yes, two whole emails) asking me why I hadn’t been posting to brainwagon lately. It’s gratifying that both of my readers would each send me a note asking if things were all right, so I thought rather than addressing you each separately, I could double my efficiency by […]

Minor progress on my F-22 RC flyer…

July 29, 2012 | My Projects, Radio Controlled Airplanes | By: Mark VandeWettering

Okay, I haven’t made a lot of headway, but I did at least print out the pattern for my F-22 and cut the pieces for it. It’s literally the very first time I’ve done this, so the pieces aren’t perfect, but they aren’t bad. Witness: I basically made the patterns by printing out the pieces, […]

My OpenBeacon is on the air…

June 4, 2012 | Amateur Radio, My Projects, QRSS | By: Mark VandeWettering

Sometime last week, I got my Etherkit OpenBeacon kit in the mail. Like many of my projects, it was probably destined to sit on the shelf for some time, but in a fit of personal productivity (for a loose definition of productivity) this week I cleared a few hours of my time and got it […]

The Beaglebone: an $89 Time Machine…

May 28, 2012 | Computer Science, Emulation, My Projects | By: Mark VandeWettering

At the Maker Faire, I splurged for a little bit of computing hardware called the Beaglebone. It’s an $89 ARM based computer that runs at 700Mhz, and includes a MicroSD card slot and Ethernet, as well as a USB connector. I wasn’t sure what I was going to use it for, but I frankly can’t […]

A Tale of Two Gadgets: the TonidoPlug 2 and a Bus Pirate…

March 30, 2012 | Hardware, Microcontrollers, My Projects | By: Mark VandeWettering

A few days ago, I mentioned that one of my servers had died. I spent some time thinking about how I would replace it. I like having a 24/7 hooked up to the Internet to serve as a file drop and a place where I can use SSH to connect to other devices on my […]

Lunch with Ken Boak, the Nanode, and the evolution of the Arduino platform

January 3, 2012 | Arduino, Hacking, Microcontrollers, My Projects | By: Mark VandeWettering

Today, through a bit of serendipity involving twitter and the web, I managed to have lunch with Nanode designer Ken Boak, who happened to be on an unrelated visit to the Bay Area this week. We exchanged brief messages for the first time a couple of weeks ago, as I was intrigued with his idea […]
