Re: Drozd Blackbird "Sergey's board - 2" (9-24V, 400-2000 RPM, Full auto, 4-12 m

Holy cow! I am busy for a couple of days and come back to find out DUBB is sportin' wood, and Cam has his board in hand ... that isn't sounding right...

You blink and look what you miss!! What does CB stand for? I was calling it SB-2 for Sergey Board 2.

Sergey- is that the same small 900 rpm board that I have?

I wish I could get a better recording of the sound, especially with the bigger valve. It's a deeper sound. The regular drozd valve sounds cool, too, though.

I wanted to do a video of the actual firing with the blackbird mag, but that was too much to do with just two hands. Yes, I was getting airshots with longer bursts and could hear the mag "filling up" after the air shots. In addition to making the new mag that will be able to do 2000 rpm in .177 and .236 caliber, I think I can make the Blackbird mag run at that firing rate with a couple of changes. But, of course, we'll have to see if that pans out.

Re: Drozd Blackbird "Sergey's board - 2" (9-24V, 400-2000 RPM, Full auto, 4-12 m

OK folks, here's my report on the new board. I tested at 12.6v and 16.8v yesterday using the Blackbird magazine, at 1100 psi. All works AS EXPECTED!!! Very nice work Sergey!!! What a sound signature 2000rpm has! Pretty cool! It sounds to me like my pneumatic air hammer or impact wrench.

I went though testing without using a jumper wire to increase voltage to the mag motor. The Blackbird mag cycles perfectly to 1400 rpm, in all modes. At 1600 rpm, I began to get intermittent air shots. 1800 rpm to 2000 rpm, I got lots of air shots. I found that 1600-2000rpm works good in 3-5 round bursts. I could actually hear the feed trying to catch up!! I EXPECTED this to happen folks. THIS IS NO FAULT TO SERGEY'S NEW BOARD!


As with TBK and my own testing of our prototype mags, we had to find the right motor with the right rpm to voltage curve, to make them feed correctly. The Blackbird motor, as suspected, MAY need to be swapped out. BUT, I have not tried the jumper wire for direct battery voltage to the mag motor yet. And to anyone experimenting with this new board keep in mind I would NOT recommend any much voltage above 15v to the Blackbird's motor!!

Be SURE to review Sergey's first post in this thread. Very important info to keep in mind! I just want everyone to be aware that this new board is experimental for finding the right voltage, and maybe the motor. Now we need to get the feed right! Sergey's new board works EXACTLY as he said it would. In fact, it actually works BETTER than the mag motor provides (without the jumper wire). Sooo, ....Don't be disappointed, you now know the facts!

In conclusion, I HIGHLY recommend this new version for the circuit board. A new era has begun for the Drozd!!! Let the experimenting commence!!! :smash: :rotflmao: ---Cam

Ok Folks! The Sergey CB#2 is installed!! WOW!!!!!! A new sound signature will be noticed now!! COOL!!! Great work Sergey! Your board works flawless as usual. And it dropped in replacing your Sergey CB#1 board exactly. All my control buttons lined up perfectly! Fantastic, my friend!

Here it is #2!!:

I think I'm getting a stiffy! I can hardly wait until I get mine, I already love that sound. Well, that used up my good idea for this year. Don't want to overload my braincells, they have both been working too hard!

You can use on-board 15 volts voltage regulator or by-pass it. The jumper position determines what you get at the mag output. It's described in the very first post in this thread.

Off-topic: this small 900 RPM board is going soon to a Drozd owner from Southern Russia whose gun needs a new board.



It'll be installed on top of the stock board. The user will have to remove the original chip and solder 6 or 7 wires connecting the small board to motherboard. The second board not populated with components yet is for another airgunner from this forum.

Very cool TBK! Tempting, tempting......

I forget, what is the max direct voltage Sergey recommends to the mag, 16.8V? At that rpm, short burst are fine.


Haa Haaa! Great clip!

I wouldn't recommend much higher than that. Especially on very long bursts. I have run that voltage fine, but I also don't do over 50-60 shot bursts without a break. 12.6v is what I normally use for the BB mag. Testing will prove today whether 2000 rpm will hold up. Seems like TBK's test was working! I'll be starting the trial test at 12.6v, then I'll go higher to 16.8v. Check back later!! ---Cam

HA HAAA HAAAAAAA!!! WOWEEEEE!! That's amazing!! Thanks for the "peek" TBK. I'm all giddy with excitement now!!

Hey, what are you talking about with the video quality?? That's WAY better than mine! I can hear everything very clearly..... What camera model are you using?

You can do more videos with that for sure! Keep 'em coming.

So, tell us the news. How is the Blackbird mag holding up to a sustained burst? Are you getting occasional air shots like I expect? I really can't wait to do some testing! ---Cam

P.S. It's nice to hear your Real voice!

Re: Drozd Blackbird "Sergey's board - 2" (9-24V, 400-2000 RPM, Full auto, 4-12 m

Ok, I couldn't just stop there. I'm really short on time for the next several days so I hooked the Sergey Board 2 to my BB solenoid so I could at least let 'er rip a few times until I can get the board installed.

I was running through a standard paintball tank at about 850 psi with about 13 volts to the SB-2. P was 8 and RPM was 2K. I am operating the board with one hand, and holding the BB with the other.

I filled the mag with Daisy bbs, turned on the board and poked the "go" button. 2000 rpm was rippin!!
The first thing I noticed was the sweet sound of 2000 rpm. Its not as thick a sound as the earlier test with my larger Magnum valve, but very pleasing anyway. A "short" burst is 6 rounds. I was shooting into a cardboard box and it was more like drawing on the box. The rounds hit very close together at that firing rate.

The second thing I noticed was a bit of muzzle climb.

In summary... This thing rocks!!! Way to go Sergey! I need to do more testing and hook it up to my new electric magazines. I can't wait to put together some more projects with this board. I believe I will need another board or two. I do need to get the mini board I just got put in a gun first.

I think this board with .236 caliber in the Magnum will be the shizzle.

I tried a video with my camera... it blows. But, you can watch the numbers go really fast! The sound isn't good.



The sound in the .amr file is better if anyone wants to do the conversion.

I recorded a couple of bursts using my drozd magnum firing the valve only. It is FAST!!!!

I made the recording with a blackberry and it is in .amr format. Does anyone have a converter for .amr to .mpg or wav and want to convert the file for me? I can't install a converter on this computer.

Of course not. 1 in 4 U.S. bills tests positive for cocaine, and dogs can smell that through anything except a metal can. And furthermore, they put tags in our currency, now, so they can count it if you ship it, go through an airport with it, or with their sattelites, if you put enough of it in one place as to draw their attention to it.

Also, try to re-solder pin 2 of the microcontroller. You'll need a soldering iron with really sharp tip. If it's a difficult task for you just send the board to me, I'll repair it for free.

Dubb, there is a small resistor on the bottom side of the board, try to re-solder it (both ends) or replace it with another 1206 or 0805 5-30 kOhm resistor. If you don't have SMD resistors or don't feel comfortable soldring those small parts solder a non-SMD resistor in parallel with SMD one and see if there is any difference in display behaviour.

I did all that, already. I went over them all with the wirebrush on my dremmel tool, which also ensured it wasn't solder splatter from anything I did, which was nothing more than wires to replace the battery contacts, and 2 more to the jack for the mag. But whatever it did, was done, already, I was just looking for culprits, after the fact. I didn't really find anything. Sergy's soldering and his work in general, is top of the line, and flawless. Although everyone who is human, by deffinition, makes mistakes, Sergy's are in all likelyhood, extrememly few and far between. I made a mistake myself, once. Having 3 different jobs to do on identical cars, I accidently did a brake job on the wrong one, and ate it. I still came out ahead that day, and even on that car, since the lavor was more than te parts were, and car that got free brakes didn't care too much. I just had too damn many Honda Accords in front of me that day, and I was in a hurry to get them done, is all. It happens, but rarely. That was the only time. Few and far between.
I hate Honda Accords. I thought that the Sarurn SL2 was a much better car, and for a lot less money, and had the benefiet of NOT being the most likely car to be stolen, in America. #2 is a Toyota truck, if you were wondering. People want what they think everyone else wants, or has, and don't know nearly as much about cars as I do, since I made my living working on them, or they would all want Saturns, instead. MUCH better car, and more reliable, too.

I know exactly how you feel about that. That was my plan, since I am the same way. I had an issue back when I was into installing modchips in Playstation 2's. In the end I was glad to learn that it came down to the chips disabling the read-error stops, and ignorrant users who don't take care of their discs, and weren't smart enough to figure out that if it isn't reading the disc by now, it is never going to, and were willing to wait as long as it took to blow the BA5815FM IC that handled laser function. Good to know, I quit doing them entirely. Other than that, I just like to know how the user screwed it up. Working on computers is all about how the user screwed it up, and finding ways to prevent them, or at least preparing for that eventuality. An ounce of prevention, as they say.
And I really want to know how I did it, too. I did not reverse polarity, I know for sure, since I appearantly did once, and had to replace that diode you put there to protect it from that, and I went over everything I could, and never found any clues. It's bugging me.

I don't know what the hell I did, but my display went out. Mostly, anyway, it flashes randomly, every now and then, but nothing that means anything. The amazing thing is that the board still works 100% othwise, everything works except the led's

Send it back to me for repair, I've never heard anything like this before so I'm curious what it can be.

When I did the 21v and back into the stock phaze of my "modular mod", I don't know what the hell I did, but my display went out. Mostly, anyway, it flashes randomly, every now and then, but nothing that means anything. The amazing thing is that the board still works 100% othwise, everything works except the led's. And I cannot for the life of me figure out what I could have done wrong to piss it off like that. I intend to send it back to Sergy, not to complain, or anything, but I really want to know how I managed that, and if I were Sergy, I would, too. I just have to work out an arrangement to pay the return shipping, I don't excpect Sergy to fix it, I broke it, and it still works, as-is, I don't care about the display, other than wishing it was blue. But since I found a way to screw something up, which is really hard to do to Sergy's boards, I feel obligated to let him figure out what I did, so he can learn from it. When I get my 2000 rpm board (I get #5!!), I'm sticking the old one back in the box, and sending it back to "it's source", along with return shipping to get it back. It still works, after all.


Yeah, I'm gonna do the same. I just need to be more sensitive about how I say things here. You all know me. I never, ever mean any disrespect! Especially about Sergey's engineering. His is "world class"!! And I certainly couldn't be more impressed with his amazing circuit board!!

In my experience, the secret to happiness is learning to sort out the occasional good idea from an endless body of bad ones.

I'm a Toxic Agent on a dangerous mission so secret that even I don't know what it is, and if I did, I'd have to kill myself!

Shame on you Cam!!! Stop scaring off my customers! Tell them what's happened to your board. Or just send it to me for repair before you damage it completely.


I SO publicly apologize Sergey! I would NEVER put down your AMAZING engineering!!!!!! I feel like a real ASSHOLE that my words came out wrong!! I meant to say that It's ABSOLUTELY MY FAULT that I shorted Sergey's board! I'm in the middle of testing for a new prototype magazine and I accidentally crossed the wrong wires.

Sergey's circuit boards work absolutely FLAWLESS!!

I Can't Say better words that Sergey's board is the BEST tech out there ANYWHERE to advance the world of BB machineguns!!!!!!!I cannot say enough about my good friend Sergey!!!!! So sorry! ---Camracer
