I have Gunner2's prototype circuit board.
I will shortly be doing a video/photo tutorial of the install. Next phase is testing. And then a video of how it works. All is coming along. Soon it will be available. Stay tuned!! ---Cam

Hey Cam.... Been a while but with the warm weather i am here to use the out doors. This is awesome. I have been hoping for a full auto mod for a long time. I had a great "barrel extention" made for me for the ebos. Looks like a real steel MP5 can. Looks great made out of steel ( should have used aluminum) because that is what the company uses. Anhway forgive me if i ask a question that i may have over looked .... What is the status on these boards ?

Hi Cam,
Damn ! Wanted it to be a surprise. Was planning to ship one to you unannounced. I have five boards ready. Shall do the preliminary testing soon. Made the holes and cutout in the shell. G2. | ||||

Thanks Guys.
The PCB design is all done, except need to make a selection on the display and pushbuttons and their location. Looking at a smaller display and better buttons. Not long for the board , after its testing , to be available. G2.. | ||||

HA, I knew this was a good idea! Congrats on the progress, gentlemen, very nice work, indeed. Now here is a modboard you can sell, and you have the market all to yourselves. I'm thinking that totalh would be interested, and he has the market for it. He could deffinately move EBOS mods, if anyone could.
I like the breadboard prototype. How far are you from designing a final pcb for this?

Thank You Cam.
One has to use the Google Chrome browser for the video to work. Don't know about other browsers. Or there is a special CODEC for the video. I have been at it on several fronts. The circuit /PCB is ready (on the PC). It is designed to be plug and play, but still needs the cutout and holes in the case. Mind if you could send up the exo-skeleton. Then I could decide the display size/location and button locations.Got some more testing to do, with the small motor in place. Then I shall update the video in natural light so the display is clearly visible. Also will add another outlet to control a feed motor for the magazine. Regards, G2 | ||||

Congratulations Gunner!!! That's great news!
How long until you have the final circuit board done? We'll have to look at the locations to put control buttons and the best spot to put the display. I'll take a look at what to do with the bb feed and pass some ideas to you. ---Cam (BTW, your video link is not working.)

The EBOS is now FULL AUTO !!
BURST FROM 1 TO 10 , FA RPM - 300 TO 900 (OR EVEN 1K) SHAKE THOSE JOINTS LOOSE. The florescent light screwed up the display on the video. As always- Thanks Cam. Next is the mag. feed mod .  Found out ,the above link and all else with PB works well in Google Chrome.  Thanks , G2 | ||||

As you pointed out, it serves to lock the breech loader and enable it only when the trigger is pulled.
And it seems to nudge it upwards when needed, though that's done by the two springs. Thanks for the how-to on posting pics. G2... | ||||

I just took out the small motor and tried all ROF and burst modes. It works perfectly without the motor!
....So that small motor must have something to do with What??? I'm confused. It seems to be a "vestigial organ". Actually it MUST be there to nudge the breech block back up into position. "A helping hand". ??? I did not notice any "air shots" in any mode although.As for PB, once you have uploaded your photo there, Hover your cursor over the photo. A pop-up will open and there should be a "Share" option. Click it. Another pop-up opens click on the folder tab for "Get Link Code". Scroll down to "IMG for bulletin boards & forums" Highlight and copy the code in the box for "Full Size". Come back here and paste the code into your reply window. Now all you will see is a line of code, but when you submit your reply it will be a photo on the forum. One other helpful hint. At the bottom right corner under the reply window, there is a little square you can "check" for "Preview". If you click that square and then "Submit" your reply, you will be able to see what your reply/photo will look like before you make it public. If all looks good, just click "Submit" again. All Done! LMK if you have any issues with PB, we'll get you posting photos in no time!

Thanks Cam,
I would take the motor from its socket out. since sliding the plastic lever off the shaft may make it loose for further use. I do have a PB account. Shall go in there and look for the code. G2... | ||||

The "shuttle" or bolt DOES move back with each trigger pull with the small motor disconnected. It just does not fire off the valve, and thus no bb fired.
You want me to remove the "lever on the shaft and the tiny spring"? and try again? Just want to be clear. I have NO problem working with you on this! Just tell me what you need me to do anytime!  I'll look at it again this morning bro! The photos we upload here, most of us use Photobucket. It is a free photo/video sharing site. All you need to do is upload your photos from your computer files to there, then there is a code to copy on PB that you paste into your reply window here. I can walk you through it when you are ready. It's really simple. Just set up a free account with them first. http://photobucket.com/ ---Cam

Hi Cam,
When you say does not fire, does the shuttle attempt to move backward with a trigger pull ? When the small motor is off/ disconnected, the lever on the shaft along with the tiny spring locks the breech loader from descending, kind of a safety. Here ,in tests it works just fine, without it. the only difference is i have it out of its place. I know its a PITA, but if you could try the same, with it out of its place and disconnected and fire actual shots thru. PS, how do you post those big pics ? G2... | ||||

Ok G2, I gave the gun a test with the small motor disconnected. The gun does not fire without it connected. I have determined that it controls the valve cycling. ---Cam

Hi Cam,
With the lever and spring attached to its shaft , there is no way it can turn, i have scoped it out and all it does is a little nudge to push the breach loader upwards as the shuttle retracts. | ||||

I will try it out today and let you know.
What do you think the small motor does?? Is it there for a timing purpose? ---Cam

Hi Cam,
I was looking at some early posts of yours on a mag. feed motor build, Pretty neat i say. We need something on the same lines, only smaller. Also can you unplug the small motor and fire a few shots and tell me if there is any difference in performance. In my tests here it did not seem to make any. | ||||

Guts!! The 1 to 10 and Full auto is a given, also the burst rate. The 400 round hopper is ok , have to come up with a mod to fit a feed motor somewhere , a small motor with a screw feed. | ||||

Ok, cool Gunner! See, you know now how important it is to see the full workings! Glad I sent it ALL to you!
 I agree with the "recoil" aspect. It is not an efficient system by any means like the Drozd. Making it full-auto and select fire should be able to be done. As for a choice between the two if only one can be done, then go full auto! I would think both can be done selectively, am I wrong?? It is really just a matter of building a bigger hopper to keep the bb's flowing. Lots of experience with the Drozd and it's technology here! ...adaptable? Why not! I think there will be a whole world of electronically activated firing mech's to come real soon. Look how far airguns have come in such a short period of time! This year, mark my words now, will be amazing for auto-firing airguns. No joke there! ---Cam

The working of the gun has been analyzed and some conclusions made.
The circuit itself is pretty simple, no problem there. But there are limitations , the way the gun is designed, and this will never bring it anywhere near to a Drozd. The ROF , may be able to push 1K , a little early to say , i can confirm in a few days. Full Auto- there are two choices. Full auto for 24 shots, or a feeder mod , like in the Drozd. Looking for ideas in this area. In the gun , there is a heavy shuttle that is driven backwards by the large motor. It has a CAM that drives a Breach loader downwards , to load a single BB! and as it reaches the end of the stroke slams open the air valve , motor is turned off, ball is sent down barrel, Spring pushes Shuttle back, another spring pushes breach upward to load next ball , helped with a nudge by the small motor. It will work with the small motor disconnected . Need to test that though. This design , i feel was made to give one that heavy recoil feeling when firing, which it does well. Tests ongoing. | ||||
