I really do not want to offend you with this post and I hope you’ll try to understand this out of my point of view.
I searched the forum quickly, but could not find something related.
So, I’m basically wondering, why the ChipShouter (CW520) is not OSH
At the hackerspace there are like two ChipShouter devices. But when I wanted to lookup the actual design and not simply use them as a black box, it seems to be closed HW. I simply wanted to learn more about designing reliable and especially safe EMFI HW and afterwards probably decide to get one solution myself in private.
As I am a really big fan of your company and your projects, I would like to understand your decision in making exactly this one closed source.
I did not open one of the devs yet, because of the probably lethal voltage generated by the CapBank. … I do not want to accidentally kill one of my colleagues, cause I still need them at the moment. Maybe afterwards, when our projects are done
Anyway, I think about the design as kind of simple:
CapBank, ChargingCircuit, some FET to trigger the discharge, MCU for settings and probably some Error-State detection && Coping with these errors.
Opposite to my imagination of the HW design
–which may be incorrect, as I did not checked yet–
there is the price, which is way higher than for the OSH boards. Of course with this one, there have probably been lots of lots of research needed which is non-negligible. There is just nothing comparable… but still expensive though… especially for enthusiasts or students.
As I mentioned, I’m a big fan that just don’t want to loose his faith.
Sounds kind of weird, but this is what it is.
I would be happy, to hear from you.
Further, I’m writing this in public because I know at least a fistful of guys who also wonder.
Take care && all the best,
