More ESP8266 Experimentation: Giving it the Boot…

April 4, 2015 | Arduino, Hacking, LED, My Projects | By: Mark VandeWettering

Got a chance to play around a bit more with the ESP8266 tonight. I dug out a nice little dual output power supply board that I had got from tautic.com with the hope that it would eliminate some of the erratic behavior that I had observed before. Sadly, that didn’t seem to solve my problem. […]

Not all is easy-peasy with the ESP8266, with a short addendum

April 3, 2015 | Arduino, Development Boards, Embedded | By: Mark VandeWettering

Okay, after I did my quick video record yesterday re: the ESP8266, I continued to play with it a bit more. And, it must be said, I had a little bit of difficulty which I thought I would write up so that other people who are experiencing the same issues might be able to comment, […]

First electrons for the ESP8266…

April 2, 2015 | Arduino, Development Boards, Embedded, Internet of Things, My Projects | By: Mark VandeWettering

In the telescope making world, we call the first time that a telescope is used to look at the sky “first light”. I’ve decided to call the first time I load some code onto a new development board “first electrons”. A few weeks ago, when I did a video that illustrated some of the bucket […]

More on Arduino v. Arduino…

April 2, 2015 | Arduino | By: Mark VandeWettering

Make just published this interview with Arduino founder Massimo Banzi about the internal schism that’s currently embroiling the Arduino community. It is true that this represents only one side of the story, but it does seem that at a minimum, Arduino SRL (represented at http://arduino.org) has copied much of the Arduino LLC website without credit […]

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 […]
