A Retro Handheld Console As They Used To Be Made

Before there were Nintendo Switches, there were Game Boys. And before that there were all the successive generations of Game Boys and other consoles right back to the Game and Watch, and then those handheld Simon and Space Invaders games of the late 1970s. These devices typically packed a 4-bit microcontroller and an array of discrete LEDs, and movements in-game were simply created by alternate LEDs on the game field being flashed.

The TeleBall from [sv2002] is a handheld game in the vein of those early handheld games, in that it features a matrix of LEDs as a screen on which it can display simple games. So far it plays Breakout, and Tennis for Two, which might seem odd were it not for its built-in radio for two-person play with two consoles.

Inside the TeleBall is an Arduino Nano, a Maxim display driver for the LED matrix, and the familiar Nordic Semiconductor RF module. Control is via a potentiometer, and everything sits in a smart 3D-printed case. Everything is open-source, so should you wish to have your own you can head over to the project’s web site and grab all the files. You can watch it in action playing tennis with two consoles in the video below the break.

The original Tennis for Two created in 1958 was an oscilloscope game using an analogue computer, and is credited as the first video game created purely for entertainment purposes. If you’d like to see a recreation of it, we covered one over a decade ago.

Business Card AVR Board Updated

Evil Mad Scientist Laboratories has updated their business card AVR breakout boards to version 1.1. We suspect the changes will probably make them even more popular. The boards are designed for the ATmegaXX8 family of microcontrollers. The center has all 28 pins labeled while either end has a prototyping area. An in-system programming header is also provided. For the new version, both prototyping areas have been increased to accommodate DIP14 packages. The holes for the microcontroller are now larger so that they can hold a ZIF socket. Finally, the power and ground traces have been expanded. We’ve always like the versatility of these boards, as demonstrated in the Tennis for Two project, and can’t help wondering if these updates were made to facilitate another project.
