Bandido 2 Modified

[bernte_one]

maybe if there is anoth interest sivlerdog could get some

too late for me i have replaced the original parts with a din 5pol plug and connector
http://de.wikipedia.org/wiki/DIN-Stecker

available everywhere and cheap proofed quality

the solder points in original were not the best in my eyes

hello merc

is it possible to post the black white image of your pcb
or isn´t it available at the moment
maybe you have sprint layout or eagle files?

would be nice

[Merc]

I am working on the black and white image. I created layout in Kicad so I cannot export in Sprint or Eagle format. Not that I know of anyway.

Here is a black and white layout image without mounting holes.

yes right many many thanks

hello merc

please can you post your latest pcb files
or a black / white printout of your pcb

looks nice will try it

[Merc]

The only change I made was to remove C18(30pf). This seemed to improve sensitivity a small amount. I noticed that other Tesoro designs using FETs did not have this capacitor. Also, the GMT King Cobra(based on Tesoro design) uses FETs and does not have a capacitor in that location. I did not change the board. I can post a better black and white image if that is what you need.

thanks merc

i think the last infos are enough
after i build igsl i will try bandido

Merc, what layout package are you using? Would you be prepared to let me have a copy of the Gerber file? I have a CNC available to me and would like to duplicate your experiences.

It is possible to migrate Kicad to Eagle. Don't ask me how because it was someone else that did it here in work and they have now left the company. I suppose I could do some research though.....

[Merc]

I do the PCB layout with Kicad. Within kicad I export a Gerber file. I then use a piece of software called DeskPCB that takes in the Gerber file and does the trace isolation for me and outputs the G-Code which my V90 uses directly. Here are the original Gerber files and the G-Code which is tweaked for my machine. Since I had to zip everything, I stuck some other files in there as well.

FYI, I just noticed a slight possible discrepancy between the Gerber the layout and the Gerber files. After I had milled and assembled my board, I decided to move the speaker ground to place it closer to the regulator ground.

You are a star, Merc. I was just going to see if our PCB man could do anything with just the black and white image of the copper. Now I will present him with these! Thanks.

[Merc]

Well I ended up adding C18 back to the board. Without it I could not seem to ground balance properly.

Merc

[Merc]

Is there any problem with using a wirewound pot for a Ground Balance adjustment? I'm using a Vishay 50K 5-turn wirewound pot on my Bandio II and I'm wondering if the inductance is causing any problems.
