The Hand Steadiness Tester is a game which tests the steadiness of your hand. The player has to take the ring from one end to another end without touching it to the wire. In this the player gets 4 turns. If the player touches the wire 4 times he has to reset the game & start the whole game from the beginning.
This project consists of IC 4017, a Buzzer, a Relay, some resistors, a Push button and 4 LEDs. There is also a PCB layout given. There are many types of Hand Steadiness Testers which are very simple. This New Hand Steadiness Tester is more advanced.

Kohctpyktop: engineer of the people, by Zachtronics Industries is the first game where you have to design integrated circuits as a challenge. You play the role of an chip designer and you have to design chips using metal, n and p dopped silicon. Check it out. [via]

David on Robot w/Lasers created a handheld gaming device using an ATMEGA32 and an 8×8 LED matrix. It’s currently running a breakout-style program he wrote and the self contained platform shows a lot of potential. Complete with directional pad and A/B-style buttons, it could be great for those interested in AVR learning and development. (perhaps along the lines of the AVR Butterfly) Hmm, but it could use a catchy name . . . AVR-boy? – nah, too obvious. [via]

This is a portable battery powered Rogue-like video game- The dungeons of Doom. The game runs on Atmega32 microcontroller. So it can be plugged to any TV set with NTSC decoder. AVR to TV interfacing is done with well known video DAC made of 3 resistors and is tuned to 75Ω TV input resistance. The whole project including 9V battery fits in a box for Altoid mints. Project source code can be downloaded here. Game code is far not complete, like only one monster implemented, also player inventory has no different weapons and items. But I guess there is still some fun to se some action on TV screen. [via]

Tim made a DIY handheld electronic version of the African board game Mancala, he writes:
Last summer at our annual family gathering, I learned the African game Mancala from my wife’s cousin Danielle. Actually, there are many variations that go by that name, so I learned the one she plays. The basic game is described on Wikipedia, but I don’t see a quick link to the rules we’re using.
I had fun exploring strategies for the game, and ended up proposing three heuristics that I thought could play a pretty good game by themselves, applied mechanically. I wanted to automate them so I could play against them, but never got around to writing the program.
A while later, I pulled out a two-line by 16-character LCD display that I had bought on impulse, and felt like using it for something. And I also wanted to try using the PIC18F series of microcontrollers; I’d used the PIC16F series before, but the 18s are a step up in features and architecture and I wanted to explore them.
It seemed like a fast fun project, and I got the basic form factor up and running in a weekend, and some simple playable UI code in another evening.
