Hello all:

I am in the process of doing the "final" round of modding on the Infinus.

I am using:
- OutOfDarts Krakens for all motors, driven by (and, except for the flywheels, braked by!) IRLB3034PBF N-channel MOSFETS.
- 3 buttons on the foregrip and 2 above those for quick mode changes.
- 5 more buttons on the left side, below a 1.6" LCD display, to support GUI menu-based setting changes.
- And a small OLED display in the place of the stock Red/Yellow/Green LED to give on-the-fly info, including ammo capacity.

I am expecting 10DPS at 100FPS with the stock flywheel cage. Once I print my custom cage at the local library, that should go up to ~200FPS.

Here's my WIP "Final Version" of the code:

Here's my pin assignment spreadsheet:

And here's the wiring diagram:

Anyone spot something I missed? As far as I can tell, it will work fine.

If anyone has any suggestions as to the most memory-efficient way to write the code, please let me know.

Here is a link to the chronobarrel if you want one:

It would run you $14.99 + tax & shipping.

 

I saw it in the release news, and then the video review by coop772, and was instantly sold. I used it to test all my other blasters, in addition to calibrating the Infinus. It's a very good, cheap, non-external-light-dependent chronograph, with the bonus ammo-counter (count up and down modes!). I usually leave it just on in count-up mode for an entire game, and then look at it when I'm done. It's usually up around 1100 rounds or so. Highest I've ever seen is 1357.

 

The one problem with the current voltmeter wiring, though, is that it is always on! It alone will drain the battery in about 2 days! (based on its current draw and the capacity of the battery) I'll be adding an external switch to the main power loop when I do my next upgrade round, to curb the draw when it's not in use. It will also make it easier to upload new code, as I used pin 13 (led_pin on this board!) for the mosfet gate, which flashes when uploading, leading to some annoying revving when changing code settings!

 

Edit (2/4/19): Did the power-loop mod. It now has a switch on the cosmetic side of the stock, below the battery compartment.

I've got this to monitor the voltage:

It's a voltmeter from OOD, that I just look at in between rounds. So far, I've only gotten down to 87% charge (according to the Accucell S60), even after a full hour of warring, so I think it's pretty good in that regard.

 

Here's how the battery fits in:

I didn't even know when I bought it!

 

As for the video:

Hope that works!

 

Thanks for taking the time to read my posts!

 

Edit: I'm still working out some of the bugs produced by my upgrade, as I've been rather busy with finals coming up. The loader isn't operational at the moment, pending a code upgrade, and the velocity is a WIP.

Pretend that you don't see those!

As of now, with the stock cage, I am getting ~130 FPS at maximum efficiency settings. I have set the value down in my test program to 30 / 255, or 1.41V, to get 70FPS. The motors get hit with 1/20 sec of 6V every time the pusher returns to keep them from lagging.

 

I am thinking of two press switches on the right side of the AFG for mid-battle fire-mode and velocity selection. If that happens, I'll be adding a 1.6 in x 1.6 in OLED display to the left side, above the trigger guard, so I can have the blaster relay information to me.

 

I have 2000 EKIND waffle head darts on my christmas list, so I can actually use this to it's full potential without welting people! The on-field velocity selection would allow me to crank it up with waffles, and drop it back down with vinyl tipped darts to keep the blaster "safe". That, and the ability to suddenly engage at unexpected ranges, are more than enough reasoning for me!

 

Anyone else starting to get the feeling of an FDL, just with brushed motors, and the dart-loading feature?

I have a custom-designed flywheel cage on order from /u/Jack-Dapper on Reddit. See here for more details.

 

As usual, bring on the questions! I honestly enjoy answering them!
