I'd seen a couple of examples of people buying these little "earpick" cameras and using them as electronics inspection cameras. I then saw the NE3 earpick camera for just £6.99 delivered so thought it was worth a go. I DEFINITELY DO NOT recommend these as an item you should stick in your ear... in general I believe the best advice is that nothing should be put in your ears unless under the direction of a medical practitioner. Anyway, the £6.99 device arrived, it's pen sized, has a single button, a metal tube/probe and came with some soft silicon attachments for digging around in your ear. Curiously mine also arrived with an extra small leather pouch outside of the main box with some steel implements inside it.. again.. these aren't going anywhere near my ears, but I may yet think of a use for them!
When you turn the device on with a long press of the button the camera end of the probe illuminates with a decent amount of light. The device broadcasts it's own SSID and you need to download a slightly spurious, but functional, Android app from a QR code in the manual. In the app you select the wireless network and then you get a live image (with very little latency I was surprised to see) on your device. You can then click to take a photo or long press to create a video clip.
It's not super high resolution and is distinctly SD in it's flavour, but it's probably more than enough for inspection situations when you are out and about and away from anything better. I could certainly imagine using it to poke into little gaps and holes in enclosures and perhaps for peaking into rocket airframes. For £6.99 it's a steal.
Just to finish off here is a tiny video clip from the device.
