Thanks SONYT. You may not need a BB when the masterminds finish the mag project. You can go straight to the 2000 rpm board in one of your original Drozds.

I would imagine after doing a few installs it would get more comfortable cutting into the body of the gun, but there still is that "one bad cut" feeling. Cut small, you can always take off more but you cant add it back!
I do it all the time, actually. I filled in the mag plug hole, I once drilled out the hole over the pot, but then filled that back in when I put in Sergy's board, I have resized the holes for the buttons a couple of times. My current favorite "dirty trick" is the big, fat, black magic marker. I use ca glue for everything, even filling in the holes. I have to do it in layers, or coats, usually, I color each layer with the magic marker, magic marker under ca glue matches to the original plastic so well that holes just disappear.

Greetings DnC and all.

I can send the boards to DnC instead of the Drozd/BB owner's address if I'm asked to do so. Right, I'm really impressed with the quality of his install, I even posted links to his photos to Russian forum. Great job.

DnC,

I would want you to do the work with the LED window and buttons too. Your setup looks factory.

I don't own a BB, not sure if I'll get one or not. I have too many Drozd's to buy a BB now. Too many other projects to finish to even think about spending money on new projects.

Waiting for JimC's hi-cap mag... :rolleyes:

I am starting to get my projects done though, going slow but steady, cleaning my "lab" is the first and most important on the list. Can't do anything else until thats done.

Someone left a comment on one of my videos asking how much would I charge to mod their gun if they sent it to me. Assuming he meant installing the new board, I kicked the idea around when I was doing the install. All the cuts can be saved on the CNC, the buttons and windows could be pre-made in bulk, and all they would have to send would be the gun body/grip and the board. Hmmmm.

Well, I'm not in this for the money (that all keeps flowing out in regards to the Drozd) and I couldn't think what would be a fair price as I don't know how long the install would take once it became second nature.

This is not the board we've recently talked about, it's a small simplified Drozd-compatible board I developed long ago.



Here's what's under the white shrink tube, plus some more components on the other side.



It takes more patience to install :smile:



Originally, it was made for AK-47 CO2 replicant but ROF was increased later to 900 RPM. The rest just mimics AK-47 behaviour: it has trigger button, a switch to toggle between single shot or full auto modes and the third button to adjust pulse duration. Each time that button is pressed the pulse is DECREMENTED by 1 millisecond, available values are 15 to 3 mS. This value is remembered even when there is no power in the batteries at all. The board supports Blackbird-type magazine. As you can see, this board is more "experimental". Though it's cheaper, only a person with skillful hands can cope with it.

P.S. "Sergey's board" ver. 2 is coming soon.

OK, genltemen, I'm starting working on these modifications. Please be patient, it'll take some time. See, writing a program and writing a program that works are two different tasks :smile:. I mean, after those small code modifications I'll have to check it works exactly as it's supposed to. I'll tell you later about the hardware modifications I'm planning, I only have raw concepts now, I need to experiment with the hardware to choose the right variant.

Below are the aswers to your questions. Technically, the IC on the board can be reprogrammed but what for? Increasing the ROF will also require changes in schematic. How do those PS and other stuff flash files become available? By the way, the cost of that firmware is at least 80% of the product price. When these devices are produced in volumes some nasty technician makes an illegal copy of the file, i.e. steals somebody else's intellectual property. It's legal in case of that router, its manufacturer puts the newer files to the web site and the users can download them for free.

Do you mean the original chip? Someone must have found a way to dump it, if not, they did a hell of a job writing the BBMax 1200rpm chip from scratch. And this isn't really the kind of application where securing the source would really be a priority. They never figured out how to stop the Chinese from cloning every ps2 modchip out there, and those are all about the code. Unless somone wants to clone the whole BB, what would be the point, asside from preventing that BBMax from being created, which obviously failed. And besides, Sergy has prooved that recreating something from scratch, even better than thiers, isn't outside his skills. As far as microcontroller programming goes, the BB isn't that complicated, it's just a pulse generator. I'm not saying I could do it, but there are far more complcated programs than that. And even those have a way of being dumped. I have dumps of every game console cartridge ever made, I should know. Am working "sonic the hdgehog", making his eyeballs red, and making the title say "Chronic the Hemphog".

Dubb,

The particular chip that the Blackbird uses can be re-flashed.

But if the program that is flashed into the chip is locked, as the chip has a locking feature, then it cannot be re-flashed.

You cannot even read the program that it has been flashed with.

I touched on this back when the Blackbird first came out.

We were trying to figure out how to do the mods to it.

I'll see if I can find those posts, and bump them up.

I believe the chips are locked, so they cannot be re-flashed.

Not sure if Sergey has his locked as well.

Locking the chip is part of the programming.
Actually, those microcontroller chips are like CD's and DVD's, they come both ways, burn one time, and reburnable, the former being considerably less expensive. Programming is done via a special interface, in the old days it was always rs232, but nowdays is usually usb. Now I'm making an assumption here, but I suspect Sergy programs these inplace, using the interface plug he leaves on the board, as opposed to flashing the chips prior to installation on the board. Either way is possible. In the case of the latter (which I was hoping might be the case, and would seem to be the easy way) reflashing the chips would be simple, if they were reflashable, providing you have the right programming interface, and the sourcecode/firmware ("Sergyware") ".bin" to flash it with. I just bought a $100 router, and reflashed the firmware on it as the very first thing I did with it. Those are easy.
