• Ammo Counter Mk3 – Collaboration with AmmoCounter.com

    I have partnered with Nathaniel of AmmoCounter.com to develop the ultimate ammo counter solution.  The circuit is a derivative of my MK3 design.  I am calling it MK3 SMD.  The new circuit is exactly as tiny as my MK3, but has modifications to allow the outsourcing of manufacturing.    In addition, with Nathan’s feedback I was able to put the finishing touches on some never before seen software features.  This is so awesome! Here is an official announcement from AmmoCounter.com  Nathan will be selling the MK3 SMD with my firmware, along with some fantastic accessories this year.  Check it out ~!

  • Mark 3 Ammo Counter

    Nerf, Paintball, Prop Weapons. This is the ammo counter you want~! The Ammo Counter MK3 is a remix of my previous ammo counter design and is now completely reprogrammable by you with no additional tools! There are 10 clip slots in memory, you can easily switch magazine sizes with a single button press. In addition, each clip slot can be reprogrammed by you for any starting value up to 99. Each slot will remember your selected fire mode, semi-auto, full-auto, and count up.Video tutorial: Coming Soon!Features:* Smallest Ammo Counter Circuit!* Selectable Clip Sizes* Programmable Clip Sizes (Default: 35, 25, 22, 18, 15, 12, 10, 6, 32, 99)* Programmable Fire Types…

  • Ammo Counter 2017 – New Design

    This is a small preview of the new ammo counter design I am working on.  There are two buttons on the face of the circuit that will allow you to select from preset modes, or add your own!  No more hardcoded starting count values!! More info to follow… The finished circuit will be about the same size as my previous ammo counters.

  • Ammo Counters – Researching Competition to Push a New Generation

    I have been selling ammo counters since 2009. After I made my energy sword, ammo counters were the most requested kit. Over the years, I have probably sold 200-300 kits. Back then, I easily beat out the lame old competition. However, sales dried up last year. I was busy with my EMF and NES projects so I didn’t look into it. Today, I searched around for new competition. Oh man. Things have changed. I think I still got them beat on size and price, but I need to work on my offerings to stay competitive. Old competition Hyperdyne: PR Counter Unit Bare bones / High Price. Can be made to fit…

  • Light Break Sensor for Ammo Counter

    I have offered ammo counter kits for nerf dart guns for a while now.  With a tweak to the ammo counter software’s min time between fire events and the addition of a photo sensor, you can install my ammo counter kit on a nerf gun and keep track of shots remaining in your clip even while full auto firing. What allows this to work is a light break sensor.  The part number I recommend is the OPB100Z.  It comes with an IR LED and a Phototransistor.  The LED creates a beam of light, and the phototransistor acts as a switch.  When the light shines on the sensor, the transistor conducts and…

  • DIY Ammo Counter

    Do you need an ammo counter circuit for your project and are bummed that you have to wait for a spot in my build queue to open up?  Fret not, here is a step by step how to make one from scratch! In this guide, I will detail how to build your own ammo counter for ~$25 and with only minimal soldering experience. Parts: Dual Digit Seven Segment 0.56inch ‘Common Cathode’ Display Adafruit Arduino Trinket Lever switches that fit in most projects You can use other arduinos or switch and display choices.  The linked ones were chosen for number of pins and size.  This project uses 16 IO pins from the arduino…

  • Ammo Counter – 5 years of Success

    Over the years I have taken pride in my ammo counter kit.  As far as I know, it is the cheapest ammo counter kit available.  I achieve my low price by my minimalistic design and versatility through programming.  Just 6 parts and custom programmed to meet your needs! The ammo counter kit is my longest selling kit and as the 5 year anniversary is coming up, I wanted to go through my records and count just how many.  I came up with the number of ~185 ammo counters sold since I first made them available in 2009. Year Sold 2014 25 2013 100 2012 25 2010 25 2009 10 Numbers…

  • End of life on Current ammo counters

    Stock has been updated in the store, when the current ammo counters are gone there will not be more. Pending redesign. Reasoning: I went to reorder display parts today and found that my display of choice is no longer being manufactured. The alternate display I’ve prepared is more expensive, I won’t be selling many of those. Looking forward: There are other cheaper and plentiful displays available, however they are not pin compatible with my current design of ammo counters.  A new design is mandatory to use these new displays. On the bright side: I am now offering LED holders in the store.  These faux chrome holders are for the 10mm…
