Arduino? Perhaps we need OurDuino…

March 31, 2015 | Arduino | By: Mark VandeWettering

It’s no secret that I’ve been a fan of the Arduino. More than any other board, it’s got me into hacking little bits of hardware and programming in the small, and has been part of numerous projects that I’ve tinkered together, and others that I’ve helped mentor young people with. It’s a cute platform for […]

Minor tweaks to Arduino Morse Sketch…

March 30, 2015 | Amateur Radio, Arduino, My Projects | By: Mark VandeWettering

Commenter Andy wanted a version of my classic code that could generate a tone instead of just blinking an LED. I mentioned that I had done this before, but frankly couldn’t find the source code, so I modified my existing program to implement the simplest possible tone: a simple square wave. Rather than using a […]

Tiny BASIC on a Tiny Display…

March 25, 2015 | Arduino, My Projects | By: Mark VandeWettering

Early in 2012, I posted a small version of Tiny BASIC that I had adapted to run on the Arduino. It is based upon code which was written by Mike Field, and based upon an earlier version of TinyBasic for the 68000 written by Gordon Brandly, which owes its roots to Palo Alto Tiny BASIC, […]

Using the Parallax PING))) ultrasonic distance sensor

March 24, 2015 | Arduino, My Projects | By: Mark VandeWettering

I intended to play around with some of the NRF24L01 radio modules I have around, but my brain didn’t feel up to it after a day of debugging. So, instead i dusted off a Parallax PING))) sensor that I’ve had around for a long time. I thought it might be fun to see if I […]

My version of minilife2 for the Arduino…

March 24, 2015 | Arduino, My Projects | By: Mark VandeWettering

Without a lot more explanation, I did a bit more work on my implementation of Conway’s life, reducing the overhead so I can implement the full 128×64 bit resolution of the OLED display. I also hardcoded an initial pattern: the classic Gosper glider gun. It runs at about 1.625 frames/second, so a new glider is […]

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 […]

My first try at an inexpensive 0.96″ OLED display…

March 17, 2015 | Amateur Science, Arduino, Development Boards | By: Mark VandeWettering

As my recent video showed, I have a lot of development boards. I also have a fair number of little boards that are useful to plugin to these development boards to accomplish various tasks. Yesterday, I received a little OLED board that I thought I’d try hooking up and let you know about my experience. […]

A 6M beacon using the NT7S’s Si5351 board…

March 9, 2015 | Amateur Radio, Arduino | By: Mark VandeWettering

This morning, the Tweeti-verse (I can’t believe I just used that word) informed me that Thomas, LA3PNA had constructed a VHF beacon using the Si5351, and I was tagged as somehow helping: VHF beacon with the Si5351. code: https://t.co/OkgZXKFSKc , video: http://t.co/hbZl9F76Aj based on code from @brainwagon @NT7S — Thomas S Knutsen (@la3pna) March 9, […]

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 […]

Task completed: Evil Mad Science ISP Shield soldered together…

February 24, 2015 | Arduino | By: Mark VandeWettering

Last night, the absent-far-too-often urge to fire up the soldering iron and make something hit me, so I warmed up the Weller and did this: Soldered one of @EMSL ISP shield kits together tonight, and burned a bootloader on 328. #babysteps pic.twitter.com/0vXo2Wewie — Mark VandeWettering (@brainwagon) February 24, 2015 I bought this kit quite a […]

FTDI-gate…

October 24, 2014 | Arduino | By: Mark VandeWettering

My hardware hacking friends have been all a-twitter (and all a-pick-your-favorite-social-platform) about recent actions by FTDI. In case one of my three or so regulars haven’t heard about this dust-up, here’s a brief synopsis. FTDI makes a series of chips which translate between USB and either RS232 serial or TTL level serial signals. These chips […]

Nifty Arduino/AVR hack: measuring VCC

In my previous article pondering sensors for my garden, I shamefully neglected a viable and interesting choice, the JeeNode

Pondering some sensors for my garden…

June 19, 2014 | Arduino | By: Mark VandeWettering

We’ve started a garden at our house in a pair of raised beds. I’ve been pondering about possibly creating a set of sensors to monitor the dryness of the soil in the beds as well as in the container that I have a dwarf Meyer lemon tree going in. I was trying to figure out […]

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 […]
