On calculators, Space Invaders and Binary Coded Decimal Arithmetic…

September 21, 2015 | Computer Science, Development Boards, Emulation, Math, Microcontrollers, My Projects | By: Mark VandeWettering

A couple days ago, one of my Twitter or Facebook friends (sadly, I forgot who, comment if it was you, and I’ll give you credit) pointed out this awesome page: Reversing Sinclair’s amazing 1974 calculator hack – half the ROM of the HP-35 It documented an interesting calculator made by Sinclair in the 1970s. It […]

New (more accurate) clock module…

May 22, 2015 | Arduino, Development Boards, My Projects | By: Mark VandeWettering

As I mentioned in a previous post, I was not enormously satisfied with the accuracy of the DS1307 clock module that I got from China. It was hard to argue with the less than three dollar price tag, but I was hoping that the accuracy might achieve 20ppm (less than two seconds of drift per […]

The “official” ESP8266 Wiki…

April 4, 2015 | Development Boards, Embedded, My Projects | By: Mark VandeWettering

This morning I’m still drinking coffee and waking up, but I was pointed at “the ESP8266 wiki”, which appears to be this Wiki page. Bookmarked mostly so I can quickly find it again. But it has some good information. If I haven’t teased you enough with this experimentation, consider these features of the ESP8266: It’s […]

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 […]

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 New Development Board: the ODROID-C1

March 14, 2015 | Development Boards, Raspberry Pi, Small Linux Computers | By: Mark VandeWettering

One of my recent posts highlighted the big pile of development boards that I have lying around. This week, I actually added to that pile in a couple of ways: I found a pair of Beagle Bone Blacks that I had misplaced, a couple of Propeller boards, and most significantly, I ordered an ODROID-C1 from […]
