From the post last week, you can see that I ran into a snag with the BlueFruit Feather board. It should be able to read the analog inputs separate from one another, but for some odd reason, taking a 3.3vdc reading on A0 would return 3.3vdc on A0 …

Apparently, in 1988, World Champion Gary Kasparov accidentally stalemated his opponent during a blitz tournament in Canada. Mr. Kasparov had a king, queen, and a bishop against Kiril Dimitrov Georgiev's lone king. The problem Mr. Kasparov was facing was that of time running out. In his efforts to move quicker …

Last week, when we looked at my code for the BlueFruit autostart, we came to realize that if it did not know that the truck was started, it would continue to crank, even if it was running. This is not good. Thinking about it, it seemed obvious that a simple …

Well, more specifically, suggestions, computer?

One of the cool things about having the built in JustChessEngine in my JustChess app, is the option to have the engine suggest a move for you. Of course, my engine has an elo rating below 300, so I'm not sure that I would take …

That's right! My latest project is to turn my BlueFruit Feather into a functioning autostart for my old '93 pickup. Looking back at my project prep posts, you will now hopefully understand what I was trying to test and learn from those experiments. The great thing about this project is …

There were several computer GUI systems invented already, but the first (to the best of my knowledge, correct me if I'm wrong) computer GUI that would highlight your move options after selecting a piece was that of "Daly CP". It was a …

A user of my open source app, JustNotes, made an interesting observation... if your note gets too long, you can't read it because it goes below the keyboard and you can't scroll it upward. You can read the bug tracker issue on my GitHub for the full story. This is …

According to legend, Gary Kasparov once checkmated via en passant in an on-line game. However, I couldn't actually find a detailed reference to that specific game. I was, however, able to find an article that expressed the only officially logged game in which an opponent was check mated via en …

I don't know exactly when it happened. I just know that it eventually quit working. It is one of those picture frame LCD panels with a slot in the back for a flash memory card. My lovely wife had purchased it for me a couple of years ago, and I …

Pawns can be scary things. They can en passant, they can form chains and islands, they can promote to the all powerful queen. Not to mention they can checkmate you. That's right. Even Magnus Carlsen has been checkmated by a pawn (vs. Tal Baron)*. So, if the current world chess …
