Henri, don't assume the GG is DOA. A splinter group is going to try a different
road, but the original is still a good item for sure. Lets hope for several
offshoot from the GGV1 over time.

Hi,

I´m really sad about hearing that GGv1 will be dropped and there will be no
PCB´s available. It will be a good kit even when DSO Nano will not be available
on the market any more - things change fast. GGv1 seems an unfinished project by
now, our Guinea pigs tested for nothing?.

However, can the developers release the Eagle/Gerber files for the PCBs then so
I can produce me an own one? I´m very hot getting this thing running, a Pickit3
I ordered arrived some days ago and a display is still on it´s way to me. Too
late to change things completely for me...

Best,

Henri

Personally I've decided to start drop GGV1 work and develop software to convert
the Nano into a MCA. GGV1 will still be up on source forge for anyone to build
their own, software binary files included. I might be wrong but I doubt new
pcb's will be made for GGV1.

the job.

commercially and sold by many. The schematics show it so simple anyone could
build one. It consists of a powerful STM32 MCU, a color LCD, analog switch chip
for input scaling, power supply, and a few buttons. The STM32 has a 12 bit ADC
capable of 1 million samples per second, possibly even twice that. It is fast
enough that a peak hold circuit is not needed, a 5 us pulse is enough for shape
recognition in software. If production stopped tomorrow we could quickly produce
it ourselves. They are from $50-$90 USD complete. You can't get the parts for
GGV1 for that. All that is needed is software, probe, HV supply, signal
separator from HV, and pulse stretcher. It's much simpler than it sounds. That
hardware has already been developed for GGV1 and other projects. It should fit
into a box the similar in size to Nano. You could attach it to back of Nano with
velcro. Most of the software is already available as open source or parts of
open source software. Tune in to Gamma Spectrometry for more news.
