Hi kingbob

Great write up and thanks for sharing the project with the community.
Are you able to post the codes for this.
This is something which I have been thinking about but am not very good with coding.
Any help would be appreciated

The 2 hall effect sensors i used are capable of detecting 9 different magazine sizes between them (and only using 2 inputs in the arduino). Thats more than enough for all the nerf magazines: 6, 12, 18, and 18, 25, 36 drums. But yes could add a 4 bank dip switch accessible from outside somewhere. But the magnets i used were like $3 for 50 on ebay, and only takes a few seconds to add one to a clip.

 

Btw if anyone wants the Arduino code for the circuit above, happy to share.

please do share the code (pastebin it - I assume at least 100+ lines of code)

Source files here:

Rapidstrike: https://drive.google...iew?usp=sharing

Stryfe: https://drive.google...iew?usp=sharing

 

They're pretty much the same, but the Stryfe version is setup for a switch for the trigger counter. The Rapidstrike version is set to use a hall effect sensor and magnet for the counter. Both have the code for each, but commented out the non relevant part. You'll see when you look. They'll work in any gun, i just differentiate them by how the trigger counter is activated.

 

Its pretty well commented so you should be able to work out whats what, where to change pin assignments, timings etc. 

Its currently only setup for a 6, 12, or 18 magazine. But you can easily add 25 and 36 detection. 

 

Its also sensitive to the direction of the magnets (north or south) so test before gluing any in place.

 

You'll also need the LEDControl.h library from here: https://github.com/w...ontrol/releases

If you dont know how to install a library, info here: https://www.arduino....Guide/Libraries

 

 

Any questions, happy to answer, and any suggestions, happy to hear!

Just a micro lever switch, some pics on the first page.

Ok, just a momentary switch. Did you happen to have a wiring diagram for the entire thing? I don't think I saw one on the front page.

Without wanting to sound insulting, if i still need to provide an Arduino, a power source, a counting mechanism, and trigger mechanism to make your counter work, then what does your counter actually do?

No worries!

 

Its a base kit to build a modified blaster that includes a dart counter. I also provide circuits, arduino code and setup instructions. The Arduino is available from a lot of sources so I chose not to supply it. 

 

The following variables keep me from providing a one size fits all solution. 

  • Blaster type (Semi or Auto trigger)
  • Internal or external installation 
  • Modded battery source

And once those things are determined all the other parts can be sources by the buyer.

 

Let me know if that answers your question.

Occurred to me i never posted a pic of what my Rapidstrike ended up like. I ended up adding nerf sights, and made a suppressor out of some pvc pipe from a hardware store. 

Put a 9 LED flashlight on the right hand side, which just has a rear mounted pushbutton switch.

Put a laser on the left hand side, which has a momentary switch on the grip in just the right spot for the thumb. (Its the red dot behind the motor switch).
