You post pics but first uploading them to a site like "Photobucket.com" then you can share them. The "img" full picture link code seems to work well on this site. I'd like to see how you installed the board. Did you take pics during the install? Does it come with the buttons and the red screen material that I saw in some other photos?

hi to green dots and kofa2, to answer your questions the board took about three weeks to come but that was over the easter period including the bank holidays. In UK drozds come with a stripped down board and no switches so this board is a huge improvement for me, also being able to adjust the pulse width can increase fps in longer barrels which i think is why i didnt see any improvement in increasing the pulse 0ver 6 on a standard barrel. The shots selector works perfectly as does the rpm selector and what is great for standard mag drozd is that every shot fired is counted in the display so no wasting air on an empty mag. I did fire a few shots using my 18" tgms barrel which is damaged and got an average of 750 fps with one freak shot of 830 fps i think what i realy need is a good quality hpa bottle and reg from jds but i am trying to buy a blackbird and accesssories on the other site at the moment so i will have to wait and see. How do you post pics on this board?

Dear KOFA2.
It's 580 FPS with 6 ms pulse duration setting. Original boards generate pulses that are 6.5 ms long. With the new board you can set it to 3...15 ms to compensate for low batteries/pressure. Please watch this video: http://www.youtube.com/watch?v=W8A0CiuWs3M (figures are in MPS). | ||||

hello aussie189..... i've been following the progress of the BB with great interest & while i'm an ancient & still use the drozd w/co2, which suits my needs, u have me puzzled..... before sergey's board u had 585fps & w/the board it's 580; aside from more bells & whistles what performance improvement has the new board brought?...... stay well and keep at it..... pops

Greetings and Good Evening Aussie189. This indeed great news. I believe you are the first to report on tests with the new board. It works! My board is about 2 1/2 weeks away.The BIG QUESTION IS ,your gun is it a regular older drozd or a Blackbird? Please report back. In your dry firings,did the gun cycle well ? Did all the features work,eg burst fire 1-10. Also how long did your board take to arrive from when Sergey sent it? GD. PS. Welcome to the forum.We are all here to help.

Hi everybody, I ordered a board from sergey which arrived about a week ago, the board looks very well made and i love the blue light. before i fitted it i took an average chronograph reading with my old board and set up which at the moment consists of the standard barrel a second hand hpa tank and reg outputting about 800psi and four aa duracells and four 3v cr2 batteries. The average with the old board was 585 fps, the average with the new board with the pulse set at 6 was 580 fps which is very good considering all the dry firing i did when fitting the board and testing the buttons. I am now looking to upgrade my setup to take full advantage of this great board.

Greetings all.I was talking to Konnanstin a while back.He has Sergey's board installed on his Blackbird and reports no problems. Also there is 10 or so of these boards being used in Russia. Ray must of got 3 really bad boards for all three to bum out. Maybe they got damaged in transit. I got my board coming in about 3 weeks and I will do testing.I don't have a Blackbird yet maybe next week. Maybe a good thing Ray to send the boards back and let Sergey have a look. GD.

This is GAT's board test.
http://www.youtube.com/watch?v=OEp0sDf8KAo This is the board for Green Dots. http://www.youtube.com/watch?v=WVCn94uW1QM Both boards demonstrate similar results: 8.4 A peak current at 9 volts, 16 A at 17 volts.

SONYtec,
Honestly, yes I have an update, I just did not want to post it. It's not good news. Like I mentioned I was able to get the gun to shoot what I would call normal strength (560-570 fps) on a factory gun using 9v and 15v and standard hpa. I was gitty like a school girl thinking I am going to make these work only to be slapped in the face by another problem. The boards do not reliably actuate the magazine. Immediately I suspected the magazine, checked that mag in a different gun, it worked great. Tried the other gun's mag in the test gun no go. All I would get is sporadic on and off, acting as if there was a short. That was the first board, the second board I could not get to actuate a magazine at all. Zip, zero, zilch nothing. Yet the mags worked fine in the other guns. I thought to myself ok, maybe this is being caused by the fact that I had added a second cap to these two boards and later removed it. Maybe I had messed something up during that process. I looked and couldn't see anything, visibly anyway. I poked around with my multimeter and everything seem correct....I say seemed because I am not an electronics guru like some may think. Giving up on those two boards I thought about the board my engineer had, that one has been untouched except for previous testing. I had not attempted to "fix" this one. I finally got it back this past weekend and I ran straight into my shop to test it out. Again I was excited and when I powered it up, it fell flat on its face, no power to the mag at all. Not during power up or upon pulling the trigger. I don't know what else to do, I have torn apart several guns trying to make these boards work correctly and I simply cannot get them to and I have no clue why. I am giving up and sending all 3 back to Sergey so he can tell me what went wrong with the boards. Something had to of gone wrong, I am not an idiot and I know Sergey is not either so the only thing I can think of is possi [ Continued ] View Rest Of Post

 EDIT: this post is only to show how bad one particular highway gets during the rainy season, as it is not a paved highway. Was being funny as GD may have to wait a bit longer than expected due to delivery maybe being held up because of that highway mess. Just thought it was interesting. I ran across this in a search for the town he is in. Some how Sergey has taken some personnal offense from this post, thinking somehow it is showing some sort of "jab" at his technical abilities. I don't see any commonality between road construction, or the weather for that matter, and electronic engineering. I don't see how that could be understood as that, since he has videos showing what he has done.

Greetings all. Money is sent to Sergey. It was painless.I used Vigo which is part of Western Union and pretty cheap.There was an exchange from Canadian dollars to US and a reasonable service charge. The total bill with the exchange was $143 on $130 US. If anyone else is interested in ordering a board, you need to get contact info from Sergey. Sergey will shortly be mailing my new board and I get to wait.Maybe 15-21 days be airmail.The city Sergey is in is in the middle of Russia (Izhevsk) and 1200km or around 744 miles east of Moscow. One huge country. Can't wait to get the board and start testing. GD>

I have just ordered mine...couldn't have been easier...Western Union handled the funds transfer
BTW - my original stock board's output to the mag got damaged, which Sergey is able to provide repairs too! To pass along my board to him shipping only cost me about 3.00 through the USPS...cheap! | ||||

Hello Sevendust63.
It's USD 130 including shipping to US. I'll have the next batch of boards available next week. The shipment will take 3 more weeks. Before you order it I'll make a video with the board marked with your name showing its performance. | ||||

Totalh,
Understood. Let see what happens this weekend. My thought, for some reason the soleniod plunger is losing "umph" and needs to be closer. Part of that thought is that the pulse is not long enough to hold open the valve to get enough gas.

I didn't use these batteries with Drozd actually -- they were installed in a 600 cc Honda CBR sportbike replacing heavy lead-acid battery. Simply amazing Lithium batteries. 100 A peak current from a thumb-sized cell! | ||||||

Just trying to think tank the problems he is having. In some of my other posts I talk about discharge rates and that is why I suggested he try higher voltage, but also with different battery capacities and compounds other than the xenos. Both my Birds wont work with xenos but work well with Ultimate lithiums which have a fairly high discharge rate, especially when compared to the xenos. But, we're not dealing with stock boards here so this may not be relevant.
Those batteries Sergey suggested have extremely high discharge rates which is probably why they work so well. | ||||

Absolutely not. These new boards push the same or greater current pulses into the solenoid. Please watch the video.
It's a matter of so called "internal resistance" of the batteries. It's the conduction losses in the battery chemical part and other elements. Some types of batteries are not designed to supply high currents. The current flowing through the solenoid discharges the capacitor. When the pulse ends the capacitor is charged from the batteries. How fast it happens depends on the capacitance and the battery internal resistance. It's so called RC-circuit ("R" stands for "resistance") and the product of this multiplication is the main limiting factor. Some batteries can't charge the capacitor to its initial voltage fast enough so the second, third, fourth and the next shots get weaker. By the way, the best batteries I've ever dealt with were those produced by http://www.a123systems.com/a123/products . There are also batteries with similar chemistry and charachteristics produced by other manufacturers. | ||||||||

Totalh, have you tried it with max voltage yet? 6 - 3.6 xenos might get the solenoid jumping. One of the components that differ is the original boards have a 16v capacitor, and Sergey's has a 25v capacitor. Maybe at lower than max voltages, it's not sending enough juice? ? ?
Edit: On the other hand, I know from experience that some of these boards do not react well to the Xenos which also causes a weak strike. Maybe higher voltage from a tool battery or piggy backed AA like sevendust did? | ||||

Greetings all. Finally some progress. For the life of me, I don't khow why moving the selenoid and collet so close works. Hopefully more testing on the weekend will resolve this issue. GD.

Just a little note -- the solenoid in this test was in its original position. Watch the video again, it compares two boards and demonstrates the main principle: similar pulses --> similar solenoid behaviour --> similar velocities. If you want significantly higher FPS, increase the pressure and/or barrel length, then adjust pulses amplitude/duration to the optimal values. If you are satisfied with some small FPS improvement, just increase the voltage and/or pulse duration. In any case you'll be able to enjoy the new features these boards offer (potential for further voltage increase, wide variety of burst modes and rates of fire to choose from, full auto mode and digital pulse duration adjustment). | ||||||
