Fresh hacks every day
[Jason] has been hard at work on this Arduino-based low-res gaming platform. He even had a fab house deliver circuit boards to pull everything together. It's a little small in his hands, and the graphics are limited to the 8x8 pixels provided by the display. But it still looks like a lot of fun and the code was written to make adding new games quite painless. The board hosts an ATmega328 which … [Read more...]
This is the back side of [Dmitry Grinberg's] 8x8 LED matrix pendant. He had seen the other projects that used a 5x7 grid but wasn't really satisfied with the figures that can be drawn in that confined area when each pixel has only the option of being on or off. His offering increases the drawing area and includes the ability to display each pixel at several different levels. He's using an … [Read more...]
[Greg] is really working on a small scale with his LED Matrix backpack PCB. It's a toy that he designed as an activity. He constrained himself to a board which would exactly match the outline of an 8x8 bicolor LED matrix package. What you see here is the side of the PCB which will be facing the underside of the LED dot matrix module. Let's call this the top of the board. The underside has a … [Read more...]
[Bill Porter] is helping a friend out by designing a simple security system for her home. It relies on Xbee modules to alert a base station when doors are opened, or a pressure mat is stepped on. The door sensors are quite simple, and you're probably already familiar with them. One part mounts to the door and has a magnet in it, the mating part mounts to the jamb and has a reed switch that … [Read more...]
[Retro Brad] has come a long way with his 8x8 gaming device which he calls Super Pixel Bros. The newest rendition has a fab house PCB and freshly rewritten code. The game is still played on an 8x8 LED matrix, but it looks like he's sourced a version with square pixels, which is a nice touch since he was inspired by the block-based Super Mario games. Also new in this version is the character LCD … [Read more...]
[Daniel] wanted his child to stay in bed until a semi-decent time each morning. The problem is the kid doesn't know how to read a clock, so [Daniel] built him a clock. Yeah, doesn't make much sense to us either, but we've used our own shaky premises for projects so who are we do judge? He used a bi-color 8x8 LED matrix as the clock display. What caught our eye is the point-to-point soldering he … [Read more...]
A lot of thought went into [Patrick Mccabe's] Pong gaming console build. He used components we're familiar with; an Arduino as a controller, 8x8 LED modules as the display, and potentiometers (with fancy knobs) in project boxes as the controllers. But every step along the way he took care to build this cleanly and robustly. Even the MAX7219CNG drivers for the six LED modules reside on PCBs from a … [Read more...]
