I suspect DSO nano grapher is making available to anyone the same-better features than CCV1 ( inbuilt : battery, memori card , color display keyboard , probe cable with shape compensator , high speed frontend , case, smd, small size, usb programmer, usb port etc etc). I can say it only need a capacitor and a resistor to be connected to a geiger+ scintillator. This makes available to anyone a complete spectrum analizerfor less than 70 $ . The big effort is to make the translation of software from ALAIN to DSO language. This can take some time but lot of people can contribute. PLEASE CREATE A WORKGROUP, DIVIDE THE WORK IN SOME SuBWORK , DISTRIBUTE TO GROUP MEMBERS AND SHARE!!!
Discussion over on Gamma Spectrometry has changed things a bit with Gamma Grapher. The DSO Nano oscilliscope looks to be a better hardware platform for a MCA then GG V1. At least that's my opinion and I believe shared by others. 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 contribution of GGV1 designers and testers can not be underestimated. They proved a low cost amateur design could match expensive commercial products. And it proved that hardware such as small BGO crystal and miniature PMT's are up to the job.
The Nano is an open source design, hardware and software. It is made 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.
These opinions are only mine and do not reflect the opinions or plans of other Gamma Grapher developers.
