upgrade possibility? and thx

hello friend thx for hard work and lovely scope.. is it possible to make more analog channels in the same page (either with other boards or even spliting the 5 adcs into 5 channels? that would be great?? I know about the trigger sync but its not duable to open more then one page in a screen ...

You are very welcome! You can open two web-pages and switch them to "background" mode with the button so that they can both run and capture,, even if only one is visible at a time (ordinarily javascript pauses the non-foreground web-page, which totally breaks the trigger logic) -- I realize it is a bit clunky to do that.

I think a couple of analog channels from two different flea-scopes on the same page is a great possible enhancement... Possibly in place of digital capture... There are some challenges as well -- with gathering twice as much data from USB, and handling independent triggers, and handling two different sets of calibration values, but it could be doable.

As for 5 adc's into 5 channels, that would require very different hardware. And unfortunately the "raw adc input" is quite low impedance, (like 10k ohm or less) making it probably unsuitable for any kind of measurements -- and adding 5x op-amps as front-ends for 5 adc's starts to get pricey...

Possibly for the future mosquito-scope if I can do it on dsPIC33A, which should have 2x 40 Msps adc's, it might make sense to have 2 channels of 40 Msps -- that's be a nice balance of cost and performance.

by the looks the bea-scope will be pure honey....lol
Thx for answer and I understand the limitations, almost all diy scopes are 1 or 2 channels thats why I was looking for 3 or 4 max channels
For automotive work theres no need for high sampling but more channels are appreciated
when we buy the fabricated pcb its minimum 4 pcbs so it would be great improvement more channels
love the simplistic way of altering the gui page (did it in notepad, decreasing the font sizes for better split screenl) and the easy of taking measurements but that all change with more channels I know
Anyway you already have a fan just by making it opensource and being a teacher that teaches and cares about the students
You deserve to teach in the university as your dream... Big thanks from Portugal

I also love the automotive target -- I have done some you can see here -- I totally agree more channels (rather than more sample rate) gets nicer. I do hope to make it to teaching somehow -- it is especially nice when folks are grateful, so thank you for that!
