Hammerhead PCB

[WilliamN]

I am in the process of designing my own PI detector. I am a ME for a living and a electronics nut in my free time. I have been looking at the hammerhead PI detector and would like to build one to test out. I think it will be a great learning platform for me to develop my Atmel PI detector (which of course I will share with everyone when its finished )
I have the gerber viewer and will make my own PCB. Has anyone encountered any problems when veiwing these gerber files for the hammerhead. I keep getting this "self intersecting polygon error" when I open it, but when I look at the cordinates given for the error I cant find anything wrong. Any tips from people who have built this board themselves? I will use the press-n-peel method.

Re: Hammerhead PCB

if to order the PCB from Carl is unoptimal way for you, I can offer an exchange. I need in some ICs, in case a price will be optimal for me. these are very accessable in your part of world, I believe... I have also one PCB for ordinary/non-SMT version and SMT ones, if you really need...

I have tested SMT PCB and it is working good, at table. I use a small coil on ferrite core for the testing...

Re: Hammerhead PCB

Thanks guys, I would rather build my own PCB, That way I have open traces to experiment with. I will go ahead and get one from carl for my own personal use in the field =) But for experimenting purposes I would rather build my own.
Thanks again

Re: Hammerhead PCB

the effective schematic on chip has been built.. it's Shedrin's Tracker PI. an idea was taken them from Treasure Hunter project. there are not another effective ways to use integrator on op-amp and chip comparator. you can take the schematic and to do really advanced programm than to begin from absolite zero point.

have nice day
