A few more notes on my implementation of Conway’s Life…

March 23, 2015 | Arduino, My Projects | By: Mark VandeWettering

I received a couple of email and twitter queries about various aspects of the code, so I thought I would add a followup to yesterday’s post. First of all, I received a query as to whether it was “open source”. Frankly, the code is so minimal and so obvious I didn’t even consider it worthy […]

Tiny Implementation of Conway’s Life…

March 22, 2015 | Arduino, Embedded, My Projects, My Stories | By: Mark VandeWettering

I had a few minutes, so I thought I’d try making a graphics demo that runs on the tiny little 0.96″ OLED display I mentioned last week. One of the first programs I ever wrote was an implementation of Conway’s Game of Life, having learned about it from Martin Gardner’s Mathematical Games column in Scientific […]

Discovered a new tool for embedded development: platformio

March 22, 2015 | Embedded, Microcontrollers, My Projects | By: Mark VandeWettering

I’m pretty old school when it comes to development. To me, writing code is something I like to do with vi (the editor that I learned three decades ago) and compile with Makefiles, especially for code that I do myself. In general, I prefer to do my development on either Linux or Mac OS too, […]

Replacing the LCD Panel in a Samsung 303C Chromebook…

March 20, 2015 | Hardware, My Projects, Stupidity | By: Mark VandeWettering

In what quite possibly might be the most boring video ever produced, I recorded myself changing the LCD panel out of my Chromebook. It’s 17 minutes of riveting youtube goodness. Skip down to the bottom if you want to watch. But here’s the story if you’d rather just read a paragraph. My wife bought me […]

A Big Bin Full O’ Development Boards at BrainWagon Labs…

March 1, 2015 | Arduino, Atmel AVR, Hardware, My Projects, Raspberry Pi | By: Mark VandeWettering

I have an odd obsession with small, relatively cheap hardware development boards. Over the last few years, I’ve acquired a bunch of them, from Arduino to Raspberry Pi to BeagleBone Black. I thought it might be nice to just do a short video showing what I have around. So I did. Here’s a little 25 […]

Another bit of programmable hardware: the WRTnode

January 2, 2015 | Computer Science, Hardware, Internet of Things, My Projects, Operating Systems, Raspberry Pi | By: Mark VandeWettering

I’ve got a weak spot for cheap, programmable hardware. In my junk drawer I’ve got a collection of Arduinos, Parallax Propellor boards, a couple of STM32 based ARM boards, and several Beagle Bone Blacks and Raspberry Pis. Today, another entry arrived: the WRTnode. I’ve only had it out of the box for a few hours, […]

Why are tiny systems so big?

August 31, 2014 | Emulation, My Projects | By: Mark VandeWettering

The last five or so years has been a remarkable period in computing. About five years ago, I began to fear that computing would be increasingly pre-packaged: that laptops and tablets would totally take over the market and the ability to find computers which were well suited for programming and experimentation would more and more […]

My programming career began with this magazine article…

July 25, 2014 | My Diary, My Projects | By: Mark VandeWettering

From tiny acorns, giant oak trees grow. Likewise, seemingly trivial events and items can affect our lives. As a kid, I had been interested in computers for a while. I think it must have postdated the appearance of the Altair 8800, which debuted in Popular Electronics in 1974 (I would have been ten or so […]

Some example python code to fetch weather forecasts…

July 8, 2014 | My Projects, Python, Web Programming | By: Mark VandeWettering

Need to get some weather information? The website forecast.io has a nice web based service you can use up to one thousand times a day for free. I was thinking of using it for an automated sprinkler application, but just to test it, I wrote this simple chunk of python to try it out. To […]

Two more pictures from my foamcore 4×5 camera…

July 8, 2014 | My Photos, My Projects, Optics, Photography, Photos | By: Mark VandeWettering

Here are two more photos I took at last night’s camera workshop. I wanted to take something slightly more beautiful than a selfie, so I chose the Luxo statue outside the Steve Jobs building at Pixar, and some white flowers from the garden. Both were taken rather late in the day, under partly cloudy skies […]

Making a simple RC switch…

June 14, 2014 | electronics, LED, My Projects | By: Mark VandeWettering

Over the last couple of years, I’ve spent a little bit of time making fixed wing aircraft from Dollar Tree foam. The results have been interesting and fun, but I’ve found that the need to find relatively large areas to fly means that it’s harder to go fly than I would like. On the other […]

On Computer Chess, including Stockfish and SmallFish

January 13, 2014 | Computer Chess, Computer Games, My Projects | By: Mark VandeWettering

Off and on I’ve been pondering some changes to my computer checkers program called Milhouse. Most of these changes have relatively little to do with checkers per se, but are just changes to the algorithms that are common to nearly all game-tree search programs. Since computer chess has always been more popular than computer checkers, […]

Visual Cryptography

November 20, 2013 | Cryptography, My Projects | By: Mark VandeWettering

I read an interesting article the other day. I’ll skip to the end to show you the result. Check out this pair of binary images: Not too fascinating, huh? If you print both images out on transparency though, and stack them together, you’ll get this… Hopefully that worked (with my limited CSS skills, I don’t […]

Deconstructing the Classic Atari Game: Star Raiders

November 17, 2013 | Computer Graphics, My Projects, Retrocomputing | By: Mark VandeWettering

Gasp, I know. It’s been some time since I posted here. A combination of life and work events have conspired to sap me of my usual exuberant energy for the nerdy, geeky pointless topics that I usually like to post about here. But nerdy, geeky, pointless endeavors do continue (even if at a reduced pace) […]

My Arduino bumper, with actual prints!

March 23, 2013 | 3D, 3D printing, Arduino, My Projects | By: Mark VandeWettering

Okay, our Replicator 2 went back online this week, and I decided to give printing my Arduino bumper another try. Since the last time, I have revised the program and code a couple of times. I was concerned that the various bits of solder protruding from the bottom of the board would need extra relief […]
