I like Interactive Fiction. I've made a few in French. Well done. I don't have a TI84+ but it must be cool to program and play that!
You can present your work on this forum too http://www.intfiction.org/forum/

it's an amazing story!  ;D

I've installed your android version, it looks cool. I'm sure it should be easy to port it to Pico-8.

The original concept is indeed rather strange: the main character fight men with tampons, yet they want people to have a better understanding about tampons.  :banghead:
And for a game about tampons, I find it lacks blood!

I find it cool anyway to find girls who are programming stuff.

and I don't know how are other men about this, but I don't have anything against women's period, I just find this natural, so women don't need to be shy about this.

I've made a little video to present the board:

I've ordered the PCB. I've made a little error on it which I noticed too late, but it shouldn't be a big problem and could be fixed. I hope there are not more :)

Some more sound examples:

- http://picosong.com/HUGM/ (Xenon / Spectrum)
- http://picosong.com/wseMn/ (Cauldron / Amstrad)
- https://soundcloud.com/memento-somniare/sidarduino-test (C64 SID synth)
- http://battleofthebits.org/arena/Entry/Underground+Water/26509/ (personal creation, for zx spectrum)

In addition this board has:

- a low pass filter
- arduino nano
- SD card reader
- Midi DIN-5 connector

I'll sell the PCB card alone (if it works as expected), for a cheap price like 3 or 4 € without shipping , and also some complete kits and assembled product (should be below 20 € without shipping)

The github project:

A picture of the PCB:

well, it was long, but I managed to draw to PCB. My friend didn't do it for me, instead he helped me much with advices and corrections. I've used Fritzing, and now I understand better how it works.

The PCB is almost ready for production, I'll send it very soon. It will feature:

- AY-3-8910 emulator (on atmega8), driven by the arduino nano.
- It can replay sinclair, atari, amstrad chiptunes from the sd card
- it might be possible to use it as a (very simple and dirty) AY synth! The avray creator helped me for this, for sending simple notes, I just need to code the synth now, I'll reuse parts from the sid synth)

- Sid emulator (on arduino)
- it can replay some sid files, from the arduino memory, which is limited (so tunes will be cut). I'd like to find a way to stream the tune from the sd card, it's probably possible
- it can be used as a Sid synth (see previous messages)

- 1 bit music player (on arduino)
- it can get music from the arduino memory. 1 bit music don't need much memory so this time a whole song, even a complex one, can fit in the memory. It might be possible to stream data from SD if the 1-bit music engine chosen is the same for all the songs.
- it should be possible to create a 1-bit synth, but I don't know why. Probably not an easy task.

- Mozzy synth (see https://sensorium.github.io/Mozzi/ ), which can output fun FM sounds and many other effects.

There will be also room for adding light sensors and use the whole thing as a noise box...

I'll also post the PCB sources (if it works as expected)

I think I'll keep my raspberry pi which has more possibilities...

Cool. I'm not that found of physical copies because digital versions are enough for me, but it reminded me how cool your music was. I've put the whole discography in my bandcamp basket, I'll probably order it soon so I'll be able to listen to it in my car! At the moment I'm listening to "Theola the One", it's so epic!  >:D

You music is really great! It's full of spirit and very enjoyable to listen to. The only thing which could be improved is the sound in my opinion. It rather sounds like general midi stuff (I don't know if it's the case) and lacks deepness. You might try to use some panning and effects on it. Overall, it sounds ok, but I think it could be much better if you work on it further (I'm generally more sensible to the notes than to the sound so it's ok for me)
#9
It's not the best handheld device and the keyboard sucks (especially when it comes to the "d-pad"), but you can plug a cheap usb snes gamepad in it so it's rather ok.

Hey, I've made a METAL song (Doom/Death)! I hadn't recorded anything from my guitars for years (more than 15 years, at least), so here am I back on tracks:

that's very cool and very professional looking! Good luck with the software.

Mass production means you're gonna sell some of those, right? :3

yes, of course I plan to sell this thing, either the PCB alone, or as a kit with all the parts.

Now for something completely different (but still related to Arduino):

Shiru from the 1-bit forum has released a port of his Octode 1-bit engine to the Arduino plateform. It was originally written in z80 ASM, and it was rewritten in C / Arduino code. It's not exactly the same, but still pretty good. Here is a quick recording I made (of a rather strange tune I must say):
http://garvalf.online.fr/index.php?page=blog_2017-02-12

It's very easy to set up, just upload  in the Arduino IDE the sketch in attachment from the first post there http://randomflux.info/1bit/viewtopic.php?pid=1147 , connect pin 7 and ground to a speaker, and you'll get 1-bit music!

Forget this, and try by yourself. If you need some help, just ask. And if you make a song good enough, I could even record it from my megadrive ;)

New songs (very different in sound!):

https://soundcloud.com/memento-somniare/khaos-nyx (American elite don't want you to listen to this. Made with picoloop)

https://soundcloud.com/memento-somniare/harmonie-des-spheres (Classical, made with MuseScore)

https://soundcloud.com/garvalf/danse-dhiver  (Black Metal elite don't want you to listen to this 'cos it's obviously rawer than their own music. 1-bit tune, for Fairchild Channel F, a console released in 1976 (like me)). It's a new engine made by Utz (Irrlicht Project), this genius.

I didn't know crazybus. Now I regret I do.  :banghead:

You're a good composer, I don't know why you wouldn't do something at least equivalent to Thunderforce IV!

Which page said this about megadrive? The deflemask one? Honestly, I don't know everything about the megadrive engine, but I think it's quite simple to use.

I'll have a look at pocketmusic

and another new song (for gameboy), this time an Irish Jig I've tried to composed in a traditional way: http://battleofthebits.org/arena/Entry/The+walnut+jig/24112/
