1st4bit

Mark Miller shared a wonderful project this week in our community that he made a few years back – a computer that can play tic-tac-toe against a human!

A blast from the past-TTL logic 4 bit computer plays tic tac toe against a human(me). I named it “Nibbler”
 I made this years back just to see if it could be done. I scratch built several versions of 4 bit computers, and made some simple programs to run motorized things. This prompted me to build this experiment to see if I could make a program smart enough on a machine with very small resources play a game and not lose. The larger computer was the first machine I built(actually rebuild/recreate as I originally designed this in the 70’s) which ran the game and the second smaller version was just used as a human input terminal.

 I played dozens of games against the machine, and each time it was a draw unless I let the machine win(to be sure it could).(read more)


Featured Community Project from the Adafruit Blog

This week on the Adafruit blog, we featured a great wearables project from Cynthia – a color sensing “smart skirt” with neopixels! Check out the Instructables here.

I love to sew and I’m on the LED bandwagon, oh, and it’s fashion show season. I created this skirt using neopixels, a Flora, a color sensor and an accelerometer. The color sensor takes a picture of whatever you put in front of it and translates that through the attached neopixels! I also attached an accelerometer so that when you move, the neopixels sparkle that color. Read on to see how I made it! (read more)
