Airgun silencer part 5

continues from part 4

oh my.. where has the year gone… part 4 was posted on 15 Feb 2016… <sigh>

OK, so yesterday I took an hour or two to assemble the internals…

the sensors are roughy 119mm apart.. 17 slots of 7mm spacing…

the discs are soldered to the ribs and tonight the electronics will get some hotglue as conductive protection…

here’s the schematic as it currently stands… very basic and only a proof of concept.. no revers polarity or ESD protection etc… but I’ll be careful when wiring it up.. (right Charl!) 😉

I’ll post some more soon.. hopefully a oscilloscope trace or two of the output too…

…continued on part 6…
