Hi guys.
I think the community could really benefit from cheap dso that was capable of sending data to pc or tablet/phone.
My plan was to use old Velleman PCS100A (
http://goo.gl/itj7Q5 ) dso which uses LPT port for communication.
LPT could be easily replaced with arduino to talk to scope.
To display data there are (at least) 2 options:
- use Ethernet shield and send out UDP stream (Like I did it here:
http://frenki.net/2013/12/convert-optical-mouse-into-arduino-web-camera/ )
- set up webserver on arduino to display data (questionable performance)
This is the easy way and I could do it myself...
But if we join forces we could use dso that is cheap and easily available: Hantek 6022BE
https://www.eevblog.com/forum/testgear/hantek-6022be-20mhz-usb-dso/This one uses Cypress EZ-USB FX2LP for usb and ADC communication so it's much more complex.
But probably it could still be done...
Brainstorming:
- Android devices with OTG capabilities could talk to scope directly
- Arduino with USB host shield could perhaps be used
- ignore cypress usb chip and read directly from adc
...
What do you guys think? Wouldn't it be great to have a cheap DSO capable of showing data on tablet that you already have...
