Game Show Buzzer System V3

Game Show Buzzer System

Game Show Buzzer System

I built Game Show Buzzer System V2 earlier this year, and I had someone who wanted basically the same thing, so this is Game Show Buzzer System V3 with a few very minor tweaks. I’ve added LEDs into the control box so the host can see which player buzzed in.

Once again the control box plugs into a computer via USB and can send keys, keystrokes, USB MIDI data, or serial data. Each button plugs into the control box using a TRS cable. We used 6 foot but you could easily get 10 foot or longer if needed.

For this one the client will be using Resolume VJ Software & Media Server and each button is set to send a different MIDI noteOn signal to trigger a video to play. Like any game show if you hit your buzzer first you get to answer the question! In discussing functionality I explained how we usually have a “lock out” time before another button press will be recognized. The client thought a three second delay would be fine…

But! I mentioned we could always adjust that in the firmware later if needed… Also, I added a reset button directly on the control box. This would allow the “host” to press the button to end the lockout period. This is sort of a future-proofing feature.

I think if I were building a deluxe version I would add a control to set the lockout time… something like what I did for the Tradeshow Video Player Controller perhaps. But also, am I getting ahead of myself? Since I haven’t built it yet I will say “No” but then…

Also, this could be used as a standalone system without a computer. It’s less exciting, as there is no sound or video triggered when the button is pressed, but as a bare-bones quiz game system, it would work fine. If you do want sounds it would be trivial to plug into a computer via USB and use QLab or LeMIDI for those.

I started working on a four button version of this, but now I’m thinking I might want to just build the deluxe version and hope that someone might want to purchase it in the future.

I’m also considering different button options, as these are nice and big but they’re also fairly expensive. We could use The Button or any other button for triggering things. (But yeah, people certainly like hitting that big button!)

Game Show Buzzer System V2

The name “Game Show Buzzer System V2” is a misnomer but I’m gonna go with it… See, I’ve built more than one “Game Show Buzzer” type of system since the original post but they were not documented here for various reasons… Anyway, this is a system I designed quite a while ago but just recently had someone actually want, so I built it.

See, typically I sell one (or more) of the Big USB Buttons or even these Survey Says Buttons, but this system doesn’t use multiple individual self-contained buttons, but a control box you can plug multiple buttons into. This specific system has just two buttons but the original design had either three or four, though doing up to six (or even eight) buttons would be trivial.

The control box plugs into a computer via USB and can send keys, keystrokes, USB MIDI data, or serial data. Each button plugs into the control box using a TRS cable. (That’s a 3.5mm Stereo Cable for you non-nerds in the crowd.) The TRS cable has three connections (Tip, Ring, and Sleeve) which is perfect for a button and LED.

The trick is in the code… meaning the programming is whatever is needed. For this specific build we did a USB MIDI noteOn for each button, followed by a five second lockout so no button could be pressed for five seconds. I’ve done systems where the “host” (using the control box) can reset the system, say for instance if the person/team who buzzes in first gets the quiz answer wrong, so that another team can try to buzz in and answer. Lots of possibilities, again, the magic is in the code.

I’ve built enough of these that I really should formalize things and come up with a system where you can choose the components and features and then place an order… It’s still sort of a custom thing (code always is anyway) but I think I have it down enough that a base system is in order.

Anyway, this was another fun project, though it was a bit rushed (got it built and programmed in a matter of days before it needed to ship) so there are a few small improvements I’ll be making next time.

PICO-8 Favorite Games

I’m going to start off saying I have very little history as a “gamer” when it comes to knowing what the classics are, what came before, and what things are based on. (I don’t even know all the genres.) In many cases I didn’t even read up on these games, I just grabbed the carts and started playing.

All of these games can be found at the PICO-8 web site. I’ve provided links to each below. I play them on an Anbernic RG35XX handheld console, but you can play them on the desktop or in a browser.

A Hat on Time
This game is a blast. It’s a platformer, of which there are many in the PICO-8 world. This is one where you don’t die, or… you do die, over and over again. Unlimited lives! I love that. You need to jump (and swing) over pits and around ash clouds(?) and it’s got simple graphics and minimal colors and it all just works. There are times in this game I get stick and think there’s no way I will go further, but then I figure it out! (Or try 50 times… unlimited lives, remember?)
I give it 8 out of 8 bits!

Barp the Balldragon
First of all, I’m still on the first level! I’m pretty bad at this one, but it’s so damn cute. Barp has some platform work to do, but besides running and jumping be “barps” (burps?) balls at the little creatures who are blocking his way. I’ll keep going on this one or give up. I’m not sure yet.
I give it 5 out of 8 bits!

Captain Neat-O in the Time Nexus
Hey, another platfomer! This one is a rich world with a lot of ground to cover. It’s a tough one, with a lot of creatures and obstacles to get in your way. I’ve put in a good amount of time on this one and more than once I’ve gotten stuck and a little frustrated. It is a fun one though, so I’ll probably keep going.
I give it 5 out of 8 bits!

Feed The Ducks
Okay, this game is wild. You are a cat (bonus points there) and it’s called “Feed The Ducks” so I guess you need to feed some ducks. This one did confuse me a little but I eventually got it. It’s a weird one, but also unique, so it’s a lot of fun. I’m still a little confused by it even after I “won” so I am sure I’ll do it again.
I give it 7 out of 8 bits!

ISOL8: Build & Isolate
Supposedly ISOL8 is an original arcade game inspired by old-school games like *Jezzball* and *Qix*. I have no clue so I’ll believe that. You press the two buttons to make vertical or horizontal lines dividing the screen or sections of the screen based on the lines you’ve made. You need to isolate all the bouncing balls. This is a timing and puzzle(?) game, and it’s a fun low-stakes play.
I give it 7 out of 8 bits!

Murder, Death, Chill
I asm typically not a fan of shooting games, but this one is just so simple and (well, short when I’m playing it) I fire this one up pretty often. You basically move left and right a bit and have to keep shooting (either left or right) when the bad guys come at you. It sounds so simple, and it is! Sometimes simple shooting is all it takes for a good game. Super fun shooting effects dress up the otherwise simple background. (Note: My screenshot is terrible, but the game is not.)
I give it 5 out of 8 bits!

Upward
All you can do is jump. Straight up. You can’t even move left or right (on your own). The graphics are simple, the concept is simple, but it just works. This is another game where timing is critical, and you need to map out your moves before you make them. Oh, besides jumping straight up you can also suicide yourself to start over on a level, which I’ve done many, many times. It gets progressively more difficult, so it’s a great challenge with such a minimal game.
I give it 6 out of 8 bits!

Thanks for reading! This was a fun list to make. The goods news is, I have a lot more games I really like! That means there will be a part two coming soon!

TIC-80 Retro Fantasy Computer

As awesome as PICO-8 is, it’s always awesome to have alternatives, and one of the alternatives to PICO-8 is TIC-80. While PICO-8 is described as a “fantasy console” TIC-80 is a free and open-source fantasy video game console for making, playing, and sharing games on a limited platform that mimics the 8-bit systems of the 1980s.

I somehow stumbled upon TIC-80 after I got GarlicOS installed on the Anbernic RG35XX, since it can run TIC-80 programs/games. I downloaded a bunch, and some of them were not good, and some just ran really, really slow, so unplayable, basically. But the ones that do work, work well! And some of them are a lot of fun. (Note: the not running well or fast is due to the RG35XX specifically. Things work fine on a desktop computer.)

TIC-80 being an open source project run by a guy in Poland in his spare time isn’t quite the powerhouse that PICO-8 is, but there’s still a lot of goodness there.

Since I messed around with writing code for the PICO-8 I figured I should do the same for TIC-80. And yes, it’s a sweet sweet retro feel to coding things. It’s like using an Apple ][ (or maybe a TRS-80?) circa the early 1980s. (That’s probably what the 80 in TIC-80 is for.)

Just like PICO-8 you can play games in the browser, you can write your own games (or demos, programs, whatever) and if you’re of a certain age and messed around with computers 30 to 40 years ago, this stuff is heavy on nostalgia and just plain fun.

(The image above shows Continuous Factory and below shows Sonic Mini. You can play them both in your browser!)

PICO-8 definitely has some advantages over TIC-80, but if you prefer open source, are bothered by some of the limitations of PICO-8, want to use something besides Lua (TIC-80 supports Lua, JavaScript, MoonScript, Ruby, Wren, Fennel, Squirrel and D!) TIC-80 might be worth checking out.

And of course if you just want to play games, then just do that as well. Grab a handheld console that can run them, or use the browser or desktop software. Hey, it’s free/open source so all you really have to lose is your time. (Open source joke some people might actually get.)

While PICO-8 has splore to explore games TIC-80 has surf. Just launch TIC-80 and type surf and you can browse all sorts of games and programs. Are there as many as PICO-8? Nope. Not even close. But hey, that’s okay… Like I said, it’s always good to have alternatives.

PICO-8 Game Development System (and Ecosystem!)

So the Anbernic RG35XX (and GarlicOS) sent me down a rabbit hole of searching for games, and somehow I came across PICO-8. The simplest explanation is that PICO-8 is a fantasy console for making, sharing and playing tiny games and other computer programs. To expand on that, it’s a virtual machine and game engine created by Lexaloffle Games. It is a fantasy video game console that mimics the limited graphical and sound capabilities of 8-bit systems of the 1980s.

One of the reasons I got the RG35XX is that I wanted to disconnect from the computer and phone and just focus on something (in this case, playing games) and while playing Tetris (again) and discovering (for the time) all sorts of old Game Boy games is a blast, PICO-8 is something special. These are my observations about PICO-8 and games made with it.

PICO-8 games tend to focus on game play and not flashy graphics. Some games are simple, some are complex. Some are recreations of old games and some are new (?) ideas that haven’t been done before.

There’s a community of people sharing what they make. I wanted to say “people” and not “game developers” because while people who make games might be “game developers” I think there are also just regular people who like making games and sharing them and might not think of themselves as “game developers” in the traditional sense of a “software developer”. The Lexaloffle BBS is basically a feed of “hey, here’s a new game I finished, or I’ve been working on, or my progress so far” and you can check stuff out.

You can play the PICO-8 games in a web browser, and they all seem to be free of ads. You don’t need to visit an app store, pay for a game, give it permission to read all sorts of information about you… you don’t even need to sign up for an account or enter a credit card.

I started doing web development in the mid-1990s and “view-source” was how we learned things. PICO-8 has view-source! You can click the little ‘code’ button and see the code. You can copy and learn from the code, and modify it, and fix it, and… it’s refreshing to be able to do that.

`For the RG35XX there is not an official way to run the real PICO-8, but there’s Fake-08, which has the goal of making PICO-8 games run on platforms that aren’t officially supported. So you won’t see Fake-08 for Windows, macOS, Linux, Raspberry Pi, or for the web. It just fills the gaps left by Lexaloffle.

As you may have guessed when I mentioned the view-source thing above, I have already dabbled with writing code in PICO-8. I don’t know that I’ll ever actually release anything, but hey, it is bringing fun back to programming for me. (For anyone who has written code for themselves/for fun, and for others/for work, you probably know what I mean.) When I was a kid in the 1980s I tried writing an adventure game on the Apple ][+ completely in BASIC. It was fun at first but quickly became frustrating as the lines of code added up and what I wanted to do surpassed my programming abilities of the time. I could probably totally write that game with PICO-8 today.

I should mention that the Anbernic RG35XX may not be the ideal handheld console for PICO-8 games. There are handhelds that can run the official version of PICO-8 (instead of Fake-08) and you just need to load the Raspberry Pi version onto the device. (PICO-8 is $15 for the official runtime, but if you consider you get access to thousands of games it seems like a deal.) Some handhelds also have wifi, which means you can run splore which is basically a browser (or “app store”) for games. You can also run splore in the browser or desktop version of PICO-8 and it’s the best way to check out a zillion games to see what you like.
