Mouser sells it, apparently...

Aim a camera at your screen?

If I used a webcam for the 'scope people might expect me to turn it round and use it for me, but I'm happier with audio and sharing screens.

My office is in my house, and I'm rarely presentable.

I don't understand what it does. It has no screen, just a sort of blinking light at the top of the board. I don't see anything about a useful display. They talk about "user software", even in the context of changing the trigger by customizing the "firmware". Really? I have to recompile HDL to change the trigger?

WTF is this thing?

I thought it had a USB interface and some PC software, but they don't make it clear which is why I wondered if anyone had any experience of this.

Yeah, I get it now. I tend to shy away from the gadgets where you have to find details through the grapevine, but you might try asking at eevblog.com. This is right up their alley. I bet you can start a year long thread.

It's an expandable multi-channel analog front end. Connect to virtually any digital channel (even serial ports are supported) .

... that's the display from a cellphone, which is a convenient but low-end option.

Lots of uses for data logging, that don't require a display interface.

It has digital outputs, not video (no video rate dependence), and isn't a fake product. Only real issue with it, is the input gain/attenuation aren't as flexible as (for instance) a full digital o'scope. Four inputs, though, are 100 MHz and twelve more go over 1 MHz for sample rate.

We have a FLIR thermal imager with a horrible non-standard USB cable and interface. The way to export images is to photograph them with a cell phone camera.

We have an E45 with the close-up germanium lens. It will image the hot spot on an 0603 resistor. It cost $12K.

We design electronics (on topic!) and need to know temp rise on really tiny parts. The cheap imagers won't focus close enough to scope small stuff.

We got a free sample of a Flir benchtop thing (that's another story)

but it's useless to us. They deliberately made the focus not-adjustable so that it can't work up close. The support post keeps it from working with any reasonably-sized PCB.

I think Flir bought Extech to kill their upcoming thermal imager product line.

Does Extech make anything, or do they contract all manufacturing out in China?

My guess is that there are Chinese sources of thermal imagers about to appear, with or without Extech.

But germanium optical systems will remain expensive.

I have a Seek Thermal hand held TIC, it's invaluable. At the time I bought it, it was better value than FLIR at IIRC about £400, and the affordable FLIR TICs didn't go hot enough. I do like the FLIR visible image overlay though.
