The Morse Quest game in semi-darkness to show off the dit-dahing light.

2024 Tiny Games Contest: Morse Quest Goes Where You Do

September 2, 2024 by Kristina Panos 10 Comments

Do you know Morse code already? Or are you maybe trying to learn so you can be an old school ham? Either way, you could have a lot of fun with [felix]’s great little entry into the 2024 Tiny Games Contest — Morse Quest.

This minimalist text-based adventure game is played entirely in Morse code. That is, the story line, all the clues, and the challenges along the way are presented by a blinking LED. In turn, commands like LOOK, TAKE, and INVENTORY are entered with the slim key on the lower right side. A wee potentiometer allows the player to adjust the blink rate of the LED, so it’s fun for all experience levels. Of course, one could always keep a Morse chart handy.

The brains of this operation is an Arduino Nano, and there’s really not much more to the BOM than that. It runs on a 9 V, so theoretically it could be taken anywhere you want to escape reality for a while. Be sure to check out the demo video after the break.

2024 Tiny Games Contest: ATtinyBoy Does It With Tiny Cartridges

August 31, 2024 by Kristina Panos 3 Comments

What is it about tangible media? There’s just something neat about having an individual thing that represents each game, each album, each whatever. Sure, you can have a little console with a thousand games loaded on it, but what’s the fun in that?

Enter the ATtinyBoy. [Bram]’s entry into the Tiny Games Contest is based on the ATtiny85, and the whole thing is smaller than a credit card. In fact, each little game cartridge contains its own ATtiny85, with the pins broken out into headers.

That is, although the schematic is based on [Billy Cheung]’s gametiny, which uses an ATtiny85 as the brain, ATtinyBoy’s brain is divided among each of the games.

This certainly checks a lot of boxes when it comes to contest rules and requirements, and it’s just awesome besides. We particularly like the custom box that holds ATtinyBoy and all his distributed knowledge. If you want to make one of your own, the schematic, code, and STLs are all available over on IO.

A mini Cyclone game consisting of an Arduino, an LED ring, and button, plus a scoreboard on a 16x2 LCD.

2024 Tiny Games Contest: Mini Cyclone Tests Reaction Time

Round and round goes the red LED, and if you can push the button when it overlaps the green LED, then you win. Cyclone is almost too simple of a game, and that’s probably part of why it’s so addictive.

Want to make one for your desk? All it takes is an Arduino Nano R3 or comparable microcontroller, an RGB LED ring with 12 LEDs, a 16×2 LCD, a buzzer, and a momentary push button switch.

Interestingly, there aren’t successive levels with increasing speed, but each round begins with a randomized speed value. Of course, this can all be easily changed in the code, which is modified from [Joern Weise]’s original.

This is a tinier version of [mircemk]’s original project, which uses a 60-LED ring and does contain levels. As usual with [mircemk]’s builds, this project is mounted on their trademark 3 mm PVC board and covered with peel-and-stick wallpaper. Be sure to check out the demo and build video after the break.

Don’t forget! You have until Tuesday, September 10th to enter the 2024 Tiny Games Contest, so get crackin’!

The blind maze -- a box with three buttons and three light-up panels that indicate walls.

2024 Tiny Games Contest: Blind Maze Is Fun For All

August 29, 2024 by Kristina Panos 5 Comments

If you think about it, even difficult mazes on paper are pretty easy. You can see all the places you can and can’t go, and if you use a pencil instead of a pen, well, that’s almost like cheating.

However, using a pencil is pretty much a necessity to play [penumbriel]’s Blind Maze. In this game, you can’t even see the maze, or where you are. Well, that’s not exactly true — you can “touch” the wall (or lack thereof) in front of you and to the sides, but that’s it. So you’re going to need that pencil to draw out a map as you go along.

This game runs on an Arduino Nano and a 18650 cell. There are three LEDs deep within the enclosure, which is meant to give the depth of walls. But, even the vision-impaired can play the Blind Maze, because there’s haptic feedback thanks to a small vibration motor.

If you want to play in hard mode, there’s a hidden paperclip-accessible switch that turns off the LEDs. This way, you have to rely on hitting the walls with your head. Be sure to check out the video below.

A Lunar Lander-meets-Flappy-Bird game where you must rescue puppies from a Moon base, on an OLED display.

2024 Tiny Games Contest: Save The Stranded Puppies Of Moon Base P!

August 19, 2024 by Kristina Panos 4 Comments

Usually, if something is tiny, it’s probably pretty cute to boot. [Luke J. Barker]’s lunar navigation game is no exception to this unwritten rule. And as far as contest rules go, this one seems to fit rather nicely, as it is tiny on more than one level.

Moon Base P (for Puppies) is built upon a XIAO ESP32-C3, an SSD1306 OLED display, and a single button to keep the BOM tidy. In this riveting side-scroller which sort of marries Lunar Lander and Flappy Bird, the top bar is always yellow and displays fuel and such, and the bottom is a rough, blue lunar surface over which you must maneuver your lunar lander. Keep pressing the button to stay up and avoid mountains, or let off the gas to cool the engine.

Fly that thing over the terrain, avoiding stray meteors and picking up free fuel, and then land gently at Moon Base P to save the stranded puppies. But you must keep flying — touch down anywhere but where you’re supposed to, and it’s game over! Once you’ve picked up the puppies, you must fly them safely onward to the rescue pod in order to win. Don’t miss the walk-through and demo after the break.

Zero-dimensional PONG game built on a perfboard.

2024 Tiny Games Contest: Coming At Ya With Zero-Dimensional PONG

August 18, 2024 by Kristina Panos 5 Comments

A decade is a long time to carry around a project idea in your head. Fortunately, the Tiny Games Contest happens to coincide with [Senile Data Systems]’s getting back into ATMega programming, so they can finally make their zero-dimensional PONG dreams come true (and have the chance at great prizes, too, of course).

If you don’t already get what’s going on here, zero-dimensional PONG takes 1D PONG and turns it on the short side. Imagine the light coming toward you, then moving away toward your opponent, and you have the basic idea. So, how is this done? Pulse-width modulation controls the brightness of the LED, and, well, you have to be pretty fast, although there is a small margin for the inevitable error.

In the video after the break, you can watch [SDS] play themselves using a red/green LED. Player one must press the button when red is fully lit and green is off, and player two goes when green is fully lit and red is off. The cool thing is that this game uses sockets, so it can use any LED. There are nine difficulty levels to control the PWM speed, so one can really test one’s reaction time.

If you want to build one of these, you’ll need an ATtiny2313 or something similar, a couple of buttons, a display, and the optional but fun buzzer. The well-commented code is available through [Senile Data Systems]’s site.

A small physical version of the game 2048, played with LEDs as numbers and tilt for input.

2024 Tiny Games Challenge: It’s 2048, But With LEDs

August 17, 2024 by Kristina Panos 8 Comments

Remember the game 2048? You slide numbered tiles around on a grid, combining them until you have one tile with a value of 2048 (although it’s possible to go higher). Legend has it that 2048 was created by a bored teenager in the space of a weekend to see if he could program a game from scratch.

It only took a couple of weekends for [David] to get Tiny2048 up and running. In this version, each RGB value represents a number value, and input comes from a rudimentary gesture detector — tilt it this way and that to move the LEDs and combine the ‘numbers’. As you might imagine, it was a bit tricky to use colors to represent numbers, so each one had to be sufficiently unique.

[David] says that the LED matrix is a string of WS2812 LEDs in a grid formation, controlled by an ESP32-S3-MINI-1. Although this may be overkill, [David] broke out a bunch of IO at the top of the board so it can be used in the future as a dev board. Be sure to check it out in blinkenlight action after the break!
