Counting the days till I mount my rare Hengstler...

Nice!!!!

[I'm Batman[501st]]

Nice. Could take a while to get to your preferred number. Lol!

[TK bondservnt[501st]]

wow.. I never thought the counter I sold you actually still worked!

[usaeatt2]

I'm considering installing a microswitch within the trigger group and wiring up an RC car battery so the counter increments every time I pull the trigger...

What do you guys think?

[usaeatt2]

wow.. I never thought the counter I sold you actually still worked!

 

It didn't.  I took some tinkering to get that old coil working again.  I actually hit it with 110V a few times to "loosen things up".  I'm a control systems engineer.  It's what I do!!!

[gazmosis[501st]]

what voltage runs the counter system? Can the number rotation be run with minimal voltage??

[usaeatt2]

It's a 24V counter, but it works down to about 15V.  I was thinking an RC car battery.

[gazmosis[501st]]

You can get a 15 V battery small enough to fit into your gun body or the magazine?

I don't know...  The coil can't have much draw for the split second it's energized - I wonder if something like below would have enough amperage?  I must try and see...bwaaaahahaha!!!

Wow... I totally like where this is heading!

[TrainWreck[501st]]

Wow!

Hey Aaron, very nice video! It remindes me of the day when I received and tested my own counter. Loved the click, click, click ...

 

Not sure if you really need 15 V or more. Have you tested this? Mine also worked with a standard 9V battery (which would eventually fit into the magazine slot?!), but for sure our counters are different...

[usaeatt2]

I'll have to give that a try. A single 9V in the magazine would be the way to go for sure. I tried a half dead 9V and it didn't work. Looks like I'm going to buy fresh batteries after lunch with my Mom!

50 days, really?!? Why does it take you so long? 

[usaeatt2]

I hope it doesn't take 50 days!!!

[hairball[501st]]

Cool, that would be a great mod. :-D

[usaeatt2]

Update:  I tried Tino's suggestion with a brand new 9V battery and no luck.

They made Hengstler counters for different voltages (the coil impedence varies depending on the voltage spec).

Based on a photo in Tino's build thread, his counter is made for 12VDC and has an impedence of 52 ohms.

Tino's will work with a single 9V battery.

My counter is made for 24VDC and has an impedence of 154 ohms.

Mine will not work with a single 9V, BUT I tried two 9V's in series (like shown above) and it WORKED!

 

By some stroke of luck, two 9V batteries will just barely fit inside my trimmed magazine.

So close, in fact, it looks like it was planned that way.

I've got a plan for running the power wires that will make them look like the coiled wires from the power cells.

 

Looks like my plan to have a functional "shots fired" counter just might happen...

 

[T-Jay[TK]]

Wow Aaron, did not expect that you've got enough space for two 9V batteries! Sorry to hear it didn't work with one. The spec sheet you posted was exactly the information I was looking for to share here but had no luck finding it.

 

In case you really want to go for a "shots fired" counter, don't forget to block the reset button .

 

Good luck for this mod.

[hairball[501st]]

im sooooo doing this mod :-D

 THIS.... THIS is awesome!  Looking forward to seeing it.  It makes perfect sense though, if you're going to do it!
