Oscar Sound Tech OST802 lavalier microphones. Anyone used them?

kronstadt — Sun, 03 Jun 2012 03:06:39 +0000

I want to start a discussion about the "cheap-but-good" lavalier mics that are out there. I heard that you can buy some relatively good lavs on eBay for dirt cheap. Anyone used them? Can you post an eBay link? What's your opinion?

I'm not gonna get into Lavalier mics for now - simply can't afford them (unless I find some worthy cheap deals to experiment with). But when I do, (if I'll really need to get Lavs for some wide-shot dialogues) I'm thinking to have a cheap setup like this http://www.danmccomb.com/posts/678/zoom-h1-as-wireless-lav-4x-cheaper/ with Tram TR-50 plugged directly into Zoom H1 (yes, you can't monitor, but hey it's a cheap solution). From one of the comments on that post, someone mentioned Oscar Sound Tech OST 802 lavs, which seems to be 1/3 of the price of TR50 (circa $120).

Here's a comparison/test with Sennheiser ME2

and here's another test

Have you ever heard of these OST802 lavs??? Someone even did a comparison between Tram TR50 and OST802 here http://proaudiocoalition.com/index.php/cdolan-pac/story/my_lav_mic_has_a_first_name_its_o-s-c-a-r/ (Tram TR-50 in the right ear, and OST802 in the left ear). OST802 indeed sounds very very similar to TR50 (although OST802 sounded a tiny bit "flatter", but nevertheless a whole lot more pleasant than Sanken COS11D or Sennheiser ME2).

What's your opinion?

Genus Tech has crazy deals right now

Just picked up a Genus Tech Elite Mattebox for $500!! They have some crazy, good deals right now even though it's showroom stock and refurbished stuff. Go check out the list. I always wanted one of these matteboxes but they were a bit out of my range. Also customer service seems really great. They inclused a couple other small things in the package to make sure my lenses would fit.

Graphene image sensor. More sensitive, less power consuming and cheaper

Not only is the graphene sensor 1,000 times more sensitive to light than current imaging sensors found in today's cameras, it also uses 10 times less energy as it operates at lower voltages. When mass produced, graphene sensors are estimated to cost at least five times cheaper.

How the Graphene nanostructure works Asst Prof Wang came up with an innovative idea to create nanostructures on graphene which will "trap" light-generated electron particles for a much longer time, resulting in a much stronger electric signal. Such electric signals can then be processed into an image, such as a photograph captured by a digital camera.

The "trapped electrons" is the key to achieving high photoresponse in graphene, which makes it far more effective than the normal CMOS or CCD (charge-coupled device) image sensors, said Asst Prof Wang. Essentially, the stronger the electric signals generated, the clearer and sharper the photos. "The performance of our graphene sensor can be further improved, such as the response speed, through nanostructure engineering of graphene, and preliminary results already verified the feasibility of our concept," Asst Prof Wang added.
