Looks for Range

Looks for Range (1/11)

  1. Could even use the same system on the bullet feeder... Sure the dimensions is not similar?, and you can't get it working on the steel tube. (You must have top sensor on the cone before the steel tube) But, it's just a matter of different dimensions on the sensors. (if needed)
  2. BTW, my first system is now shipped to the US and is up and running as it should!
  3. Could even get a foot pedal to turn it on/off. So you can keep your hands where it matters...
  4. You can see my solution here: Sure, it's still noisy but you are left in peace for 10-20 rounds before hell breaks loose again.
  5. You can use a micro switch at the bottom, and a timer relay that will run for as long as you state. Actually you should find a relay that has DC input and AC output. Like this one: https://www.ebay.com/itm/DC-12V-To-30V-DC-250V-AC-0-60S-Delay-Timer-Switch-Adjustable-NE555-Relay-Module/202512350212 Instead of getting a hard time adjusting the microswitch I would have used a inductive sensor. (Ring sensor) But instead of NO "Normally Open" you need a sensor that's NC "Normally Closed" NO = No output voltage when no signal. (No metal in front of sensor) NC = Output voltage when no signal. (will send signal to relay when no metal is in front of sensor) Actually the micro switch must also be NC so it will send a signal when there is no brass. (Most has both options on the legs)
  6. Yes, the problem will be that every case falling down the tube will trip the switch. As you state a timer will be a solution to do this a simple way. That's why the Arduino makes it so smooth. The coding will make the system fill the tube all time even if I change caliber. Here is a manual way of doing it: https://www.youtube.com/watch?v=sw7d2fwG8hI
  7. Well, strange enough I seems to use more primers than reloaded rounds. Or, they tend to be left in the machine due to out of bullets or powder...
  8. Well, to put it simple I did it this way, Because I can!
  9. Here is a pic how I mounted the Arduino, with the relay inside the case feeder.
  10. Here is the IR Sensor So, 5V DC will do just fine like a USB charger to run the sensor. Then you can use what counter you prefer. Sensor is NO. (Normally Open, output 0V) Maximum range: 10 cm Minimum range: 2 cm Sampling rate: 390 Hz2 Minimum operating voltage: 2.7 V Maximum operating voltage: 6.2 V Supply current: 5 mA3 Output type: digital4
  11. First, you need to do some wiring on the 110V/230V system. Then code an Arduino using a PC and wire up the sensors to get it working. To me it's not complicated but you need some technical insight. Playing with 110V/230V is not good if you do any mistakes. Besides that, the rest is simple to do. (I think) For cost eBay is your friend. You will need the following: A 12v DC power supply. To drive the sensors and the Arduino 2 inductive sensors. (I use ring sensors, so I can slide them outside the tube.) 1 Solid State Relay DC/AC version. 1 Aduino Uno + a long USB cable. (So you can update the Arduino code if needed) 1 resistor, and some wiring and tape. 1 screw terminal Cost, not sure but maybe I have used about $ 80 or so. Biggest cost is the sensors. I'm off for a couple of days, but I will see if I can post some video later of this.
  12. Hi, here is a picture of my ammo counter. Using an Arduino, a Digital IR sensor and a PC. The reason for doing it this way, is that most counting systems never count actual rounds reloaded. My sensor triggers on reloaded rounds down the chute. The software is programmed by me as well. Seems to work as intended, but I need to do a lot more testing...
