If the I2C interface to the BBAI is not needed the I2C device address jumper can be used for something else, such as to select fan speed.

Hi, I built that preamp and I got on the input of LM837 2MHz sinus. The LT1028 working like oscilator. It doesn't matter if power is coming from battery or transformator. Assuming that missing decoupling capacitors has an impact on oscilation. Looking into supra 2.0 preamp (big schema), every OPA is decoupled and has frequency compensation (https://www.elektormagazine.com/news/cool-summer-free-download-of-the-week-supra-2-0-super-low-noise-mm-md-phono-preamp) Any idea how to remove oscilation? best regards M.

This looks very cool, and I'm going to build one right away. But is it possible to increase the number of inputs?  That is, add an additional analog input and 3 or 4 more digital (switch) inputs? I know I should probably just build a modified version and find out for myself.  But sadly, I'm only a so-so Microchip programmer and know next to nothing about USB (at this level). So if my modded version didn't work, I wouldn't know if it's because I screwed up (the most likely possibility) or because it was never going to work no matter what I did. Any thoughts appreciated.

yes take your time just giving suggestion for improving project nothing else , i already made one(dirty code :/) but had some issues with UTC to local time so i came here while searching on google :)  if we already have RTC connected and its serving time then what's the point of keep writing time at every second to RTC from GPS , add a specific time eg 1-10 min option to keep it accurate yes add available satellite info too Thank you

Hello, yes, this could be added, but i guess needs to be done in the sparetime, so please don't expect it to take some time. About the sync delay or manual sync time, can you please specify a bit more what you like? Is it once at a given time or why you liek to have a delay inside ? About the Display as mentioned a bit earlyer the next step will be to get the content of both screens shown in the web-UI. Regards CalM
