Dave finds a sweet Yamaha RX-V579 surround sound receiver with all the bell and whistles in the dumpster!

What  Dave   , no  'Men at Work"  played through that  Receiver?

Dave  just smiled and gave me a vegemite sandwich
And he said
I come from a dumpster  room  down under
Where people  throw away  junk  and  other men plunder
Can't you hear him , can't   you  sit there and wonder
You better run, you better go check the   dumpster

If that Amp's HDMI switcher isn't a dumb analog switcher, IE the receiver adds on screen text menus to the video going through for display on the TV HDMI out, it might be able to take your new microscope's HDMI video in, and output a HDMI video which your USB HDMI video capture box can operate with.

Give it a try...

The HDMI switch on these are notorious for dry joints.

I'd imagine a lot of the HDMI overlay chips more or less just substitute pixels in real time, not only to save cost (no frame buffer) but also to keep latency to a minimum. (Add a few frames of delay and gamers will hate you.) Look at Bunnie Huang's NeTV project for an explanation of how it works.

Worth a shot. Bit box to have sitting around for that job though.

I still have - and use daily - the Onkyo receiver that Uncle Doug had in his "dumpster" a while back.

I have an older model at home, between the kids devices (PC, Chromecast, pie) and the projector.  Gets regular use for movie nights.  But if you have no use for it, may as well eBay it to help with the cash flow issue.

Yes, but if it works, then I can recommend an approximate 50$ HDMI video enhancer box which basically decodes the HDMI, puts the video data through a 2D convolution filter, then re-encodes the HDMI.  Should give a similar function to solve your video grabbing problem.

The video enhancer also has an on-screen text control menu to adjust the effects.

Dave, have you considered the admittedly remote but still real possibility that electronics companies (which are made up of electronics engineers of course) now might be targeting your famous dumpster with their products to get free advertising on your site?

I've heard stranger things that turned out to be true.

Also, keep security in mind!

  Instead of mailbag, I'll ship in  my expensive AV doohickey to dave's dumpster...
