Homebrew FX Chrony display
- Thread starter DaystateRebel
- Start date
Rough draft based on ideas from the group. Once I get my little magnets I will post the file. I will also work on a battery backpack

I just dropped a new version for the TTGO T-Display that leverages the OpenFontRender library. I decided against Comic Sans 
When my M5Stick arrives next week I will build on @fe7565and @Hallyster61 's excellent work: improve the fonts, auto display flip and "rifle cant'
FWIW, this is just a fun hobby/educational project that I hope gets people to try their hands at something new - Arduino programming & 3D design printing. I really like some of the cases people are coming up with !

Nice upgrades. Some of my ideas/thoughts
The "connected" text is probably unnecessary
If we're not connected we're searching (@fe7565 this was your input, any thoughts?)
Pellet weight
I can see two ways of doing that
(1) just enter the pellet weight using the UI, increase/decrease by 0.1g per click.
(2) allow the user to easily update the sketch with a list of their own pellets and then select the desired pellet from that list in the UI. I'm thinking an additional .h file where you create a table of pellet name, pellet weight, caliber (optional)
I like #2 myself - you update the sketch with just the pellets you use. Preloading the thing with hundreds of pellet definitions would make selecting the one you want painful. This would also disincentivize buying a preprogrammed device, if you want to add your own pellets then you have to modify/build the code yourself so you may as well just buy an M5stick

Thank God and thank you Rebel...I decided against Comic Sans
I can't wait to see the new implementations on the M5.
It will help if I send you the lines with all the code for the screen alignments of the data on the display?
(Looking at your name, are you a Daystate airguns fan? 'cause I'm too)

I agree, is not necessary in my opinion.
Could be... but... what happen when you turn the M5 off?
Mmmmm... seems good, but the choice must be linked to a profile.
Just my two cents thoughts...
If you switch from one level of power to another you probably also switch to another type of pellet/slug.
Or if you switch to one type of ammunition to another the easiest way is to change the profile to one already prepared, as in the FX app.
Having the profile you need hard coded in your device would make the M5 not "flexible" but surely very easy to use on the field.
Just my opinion, as @fe7565 said, this is your baby, and you must have the final decision on where it will go.

Open source, have whatever font you want
Sure, I won't get my M5stick for a few days
For sure
It would persist in EEPROM like the rest of the settings so when yourn on again it would still be there
Assigning pellets to profiles, hmm, would that be a speed profile or a gun profile?

Yes. The font has a lot to be desired. The ESP32 should have enough power to push more defined fonts.

Cold be anything you choose, as in the FX app.
This is an example of some of my profiles for the Leshiy2. Very handy, all is in the profile, max velocity and pellet weight.

Nice low profile mount. Once you remove the module nothing to stick out or fold. And you can rotate the display at different angles.
Press fit or magnetic?

Yes, the “connected” display is not necessary. But I like the small red and green dots to indicate connection

This is so awesome!
I found this M5Stack module, which has improved on the earlier devices and also features a touch screen+speaker and MicroSD card.
I'm trying to figure out if the Heltec board can export a shot string, or email it to an email address like the FX app does.
@DaystateRebel - is that possible with any of the boards that've been shared here yet?
Thanks, this is very interesting, and it'll get me back into 3D printing!

I was not aware that it has touchscreen, but surely it does. That's great. The speaker is also good so it can announce the readings. Supposed to be a revised sound interface that improved from the previous. I know that the M5StickC Plus has a buzzer, but it's mousefart quiet and can barely hear it at 3-4khz which is the loudest you can get on it. The mic, for those who want to tackle that, can be used to wake up/sleep and for menu settings, etc with voice commands.
The SDcard is an easy way to export your shot strings, although that can be done over BLE or Wifi too. The battery is also 3x larger capacity (390mAh) than the M5StickC Plus or the M5Stack "Gray". Has the same improved PMU as the M5StickC Plus, so coding is easier. And has vibration, which could be handy when using the anti-cant feature.
The two things that are negatives for me, the price and the size. The price is reasonable for the features, but does everyone want those features? May just want a quick ad dirty speed reading which th much smaller M5StickC Plus can provide..

Press fit hard plastic case going into flex tube that stretches slightly to hold tight. Also no screws needed for the picatinny. It is flex filament and press fits/snaps on.

I agree - I have bought the Heltec board for now.
The M5Stack Core 2 is a very powerful board and can do a lot of things with the additional modules available for it. It's not too expensive, comparatively, and you're right, not everyone will need all the features. Perhaps sometime in the near future!
I would appreciate if someone could point me to how I can email/export shot strings, since that is more important to me than just the readout (for long term tests etc).

No, that would just be typical capitalist competition. FX sells a 250 bar 580cc reservoir for $350, while I bought my 300 bar bottle from another company for $150 and a valve from DC for $50.
FX could have easily protected themselves with a rudimentary encryption of the transmitted data. For whatever reason, they chose not to, so that's on them.
I just hate to see hard work get stolen. I've been there, and I don't like the feeling.

And that is a shame for a number of reasons. I hope he at least creates a modified MIT agreement so he can at least get attribution for those who adopt it for commercialization. But, who am I kidding; they will just steal it with not a care in the world.
