I havent messed with one, but EBOS stands for electronic burst of steel, so it's similar to the drozd in that it has an electronic board and a solenoid hammer, yes? It'll need a modchip, or replacement board, of some kind. You need to ask Sergey about that, he designs these from scratch, and I know that he has done others besides his drozd board. He has designed some really neat ones for other bb guns, and some of those can probably be adapted, or he might just make one specificly for the ebos, if somone asked him to, and gave him the dimentions of it. In any case, that would be who I would ask first.

Sergey's board would make it work..... just no room inside for it.

Re: EBOS first step to full auto

I am just starting to read through old posts about the EBOS.

Any news out there about full auto mods? Rate of fire? Any new Youtube videos??

Re: EBOS first step to full auto

Scott,
I will follow this post religously.
I have been searching and searching for this exact info.

work on electric forklifts, so i am not new to electronics, but this gun has me stumped on where to even start.

its nice to know, someone else is out there looking at the same thing.

Rob.

EBOS first step to full auto

I'm sure my fellow EBOS owners are searching high and low for some type of info on full auto mods. There does not seem to much info anywhere on the design of the EBOS so I've torn mine apart again to hopefully start to shed some light on this. First of all, the EBOS uses a somewhat similar electronic design to that of the Black Bird. Two motors and a somewhat "typical" logic board consisting of optical sensors and an EPROM are used to control fire rates as well as "firing" the bb gun. Nothing unexpected or exotic there at first glance. My first thoughts about a simple mod were to use the Black Bird chip to obtain similar results. But, upon closer examination I discovered the EBOS uses a somewhat serious EPROM (for a BB gun that is). Umarex stuffed a PIC16F677 is this bad boy. Without confusing everybody, other than Sergey the Drozd God, by going into too much detail lets just say the EBOS uses a Ferrari's power plant and the Drozd uses an oldschool American V-8.

I'm out of time for now, but once I figure out the logic board schematic I'll post my findings. Then it's on to looking at the code itself that has been loaded onto the
EPROM.

Until then...............

Scott
