[Chris] has been hard at work building his own version of Simon called [Nomis]. Although [HAD] has featured an ATiny Simon clone before, the article does an excellent job explaining how the system works.
The ATTiny85 is used to control this game, which, for now is laid out on a simple breadboard. A PCB version of this game has been ordered from [Seeed], so be sure to check back to see the results of this forthcoming upgrade. It’s really cool that this kind of small scale manufacturing is available to the masses.
A parts list is provided as well as a code overview and schematic. To see it in action, check out the video after the break. There’s an explanation at the beginning, but skip to 1:55 if you’d rather just see the machine in action. The game can reportedly run until a 100 “move” limit is reached. This was arbitrary, but it should be enough for most people! Continue reading “A Little Simon Clone Named [Nomis]”
[Alan Parekh] and his daughter [Alexis] just premiered their entry in the Avnet Dog Days of Summer contest. It’s a game called Karate Chop that is basically an electronic Simon Says. The video after the break shows a demonstration of the device. When switched on it’ll play a little tune and start cycling the LEDs on the front of the case. Players interact by breaking the infrared beams in the two cutouts on either side of the case. You need to keep your hand flat to do this, which is where the name comes from. There are four different game modes which are selected at the start of the game. There are two difficulty levels of a Simon Says game which shows the player a pattern in light and sound, then watches for the user to repeat that pattern back. The other mode that [Alexis] demonstrates is a reflex game which requires the player to quickly react to randomly illuminated LEDs.
The circuit is built on a breadboard hiding behind the front bezel and uses a PIC 16F1827 microcontroller to drive the game. The case itself is made from laser cut MDF and plywood. We’re not sure how much time [Alan] spent on the case, but we think it looks wonderful. If you’re planning to participate in the contest you better get rolling, the entry deadline is tomorrow.

[Simoninns] is hoping to compete in the Sparkfun Microcontroller Contest with this cool little Microsimon instructible. The parts list is pretty small, at around 20 components. At the heart is a PIC 12F683 microcontroller. The whole project is very well documented with schematics, PCB layouts, code, and great pictures. This is a great project that you could put together really quickly and is a perfect introduction to charlieplexing. We find that, especially when teaching a new person, games are often a good project to learn from. The interactive and competitive nature of the finished product usually keeps people interested a little longer. You can catch a video of it after the break.

[Simon Inns] designed a circuit board to retrofit an original Simon electronic game. This hack is immediately a win because he made sure that his design required no modification of the original case. The new PCB has many improvements. It moves the device from using 2 D-cells over to a 9 volt battery, the incandescent bulbs were out swapped out for three LEDs per button, and the use of tactile switches makes the buttons a lot more responsive (but does require a bit of modification to the colored button covers). Under the hood there’s a PIC18F2550 controlling a serial LED chip and handling input monitoring and sound generation. The video after the break is safe to watch at work, there’s no swearing involved this time. Continue reading “The UltimateSIMON”
[Fridgehead] modified his Simon Says game to include a dirty word for each lighted button. This is a real good way to teach kids to swear and to get child protective services to pay you a visit all at the same time. The hardware has been modified to use an Arduino in tandem with an ISD audio chip. These chips can record and playback sound. Although [Fridgehead] could have made it say anything he, choose four words you won’t say in front of your mother. We should warn you not to play the video after the break if you’re at work or it’ll be your boss that comes after you, not your disappointed mom.
