content: The consensus is these are probably their existing Mosaic Core. Specifically, the specs seem to line up with S214SPX and S314SPX for the Nano 200 and Nano 300 respectively.

content: It may not be true, since on their forum is something like thisQuoteBut also could be Mosaic Core with custom firmware inside.But I don't think they can fit it in such small case.Maybe a new version of Micro Core.

content: I'm still leaning Mosaic core with a different interface board (or different firmware on it).The Nano is 25fps, and the best I can tell, has a shutter.The Micro core is only <9fps, and shutterless.The Mosaic core has an "up to 32fps" variant, and has a shutter.External dimensions of the Nano are 25x25x22 mm. Mosaic core is 20x21x10mm to 21x23x20mm (depending on lens), so would just fit inside the case (with room for an interface board behind the less deep lenses).Guess we have to wait for someone to get one and tear it down.

content: Ok my Seek Nano 300 is here. It's very underwhelming compared to the Infiray devices. From first impressions it seems on par with the fast frame readout Seek Compact Pro. There seems to be quite a lot more rolling shutter. I'll do a writeup this weekend.

content: Any other feedbacks about Nano 300? I'm testing Topdon TC100 Plus and I'm not happy because has hot corner, I aslo calibrated it but then I have to wait every time it heats up otherwise when cold you will have the spot. There is a design error in this camera that I find quite absurd.So I'd like to try Seek Nano 300 because it has better resolution and sensitivity, do you think it's a good deal?

content: Reading this post from lololo and it’s included quote has been somewhat of a surprise to me. I really do not know what to make of SEEK Thermal. When they first appeared on the market many moons ago, many of us had very high hopes for this fledgling company that wanted to bring affordable thermal imaging to the masses. I purchased the original SEEK Thermal dongle upon its release and was very disappointed with the amount of noise in the produced images. Since then, new camera models have been released and clever people on this forum have worked hard to improve the imagery that they produce. I still own a later SEEK Thermal ‘Classic’ dongle and several SEEK Thermal Reveal models (I just like the design!). I hoped that SEEK Thermal would continue microbolometer and video processing development to make their cores competitive in the marketplace. We need to remember that SEEK Thermal was created by clever people who used to work for Amber, Raytheon and FLIR. They are said to have used their knowledge of the FLIR Lepton to create the SEEK Thermal cores. So much so that FLIR took them to court and they were forced to introduce a matrix of deleted pixels in their early microbolometer dies ! Many years have now passed, yet we appear to still be seeing microbolometers built on elderly FLIR Lepton microbolometer technology that can be noisy.In the face of competition from Infiray and Guide Sensmart, you would think they would produce imaging cores of equivalent performance, or even better ? It would appear that this is not the caseSo how can SEEK Thermal remain successful as a business ?One factor may be their USA location. Where Government projects are concerned, there is understandable loyalty to Western technology manufacturers for reasons of national security. I can see Infiray being excluded from Government projects in favour of a “home grown” product from SEEK Thermal. This may also apply to the US public and other Western nations. Much is made of cyber security these days so including China sourced closed code for a thermal imaging core in a Western Government project does have its issues. A Chinese camera that I am about to test automatically captures GPS data without an option to disable that function

content: I do not like relying on other peoples experiences when commenting on a camera or cores performance as there can be many variables at work to complicate the ‘picture’ and user experience. I would like to buy and test one of SEEK Thermals imaging cores to see the current state of their ‘art’ in thermal imaging. Sadly I do not have the money to ‘waste’ on such purchases these days and I doubt that SEEK Thermal will send me a test sample. It will be interesting to hear what other owners of SEEK Thermal recent product releases think of the imaging performance. A test sample of just one is always questionable as it is possible for a faulty unit to be responsible for a poor user experience. I may write to SEEk Thermal and ask about a sample for technical testing but I do not expect a response !Fraser

content: The original Seek Pro FF, back in late 2016.. was highly impressive for a new consumer thermal dongle...Got one in 2017 new from a US eBay seller (sadly only iOS but maybe that was for the best, as MicroSD would be even more dated today than Lightning) and was blown away by the result that a thermal-dongle that set me back around 300 bucks could deliver, not least with a cheap IR lens from Chinahttps://youtu.be/Im1_Dyf69to?si=B-UQ4kPw2Gs9D3xh&t=65Same with the sensitivity on the crosshair readinghttps://youtu.be/FKDunIxtMQk?si=kKolU05b0mVXjYBY&t=14if you match a given material's emissivity and ain't to far way.. was pretty accurate, at least on my unit and to the extent I could validate.Framerate stays around 17 to 18Hz with the mandatory shutter.Compared to other more modern dongles I have & seen, Seek Pro FF. is noisier, but some of that is also down to being less "enhanced" like you see on fx Irays or Guide's algorithm.Two things I do like about the Seek Pro FF is the manual focus that makes the product so much more useable in various situations, and the variable span-control, so you can work with that tiny focal point that is minute.https://youtu.be/WClAAzW-xhQ?si=n5WqJnP5KIMLyRWy&t=54Been in the market since' for 480p or above dongle now that China for quite a few years been able to produce microbolometers, but the development over the last 8 years, hasn't been like I hoped for sensors above 288x384-.No dongles, and it's mostly in monocular hunting scopes you see that amount of res..Iray's representative year-after-year, been claiming that our 6-series dongles is just around the corner.Seek Nano300 the videos have seen sofar, actually seem subpar than the old Seek Pro FF, but maybe the price is also a hint when looking at Seeks own pricing Nano 300 vs Seek Pro FF that is still close to double in price vs the Nano300 "intro price.But maybe its nano200 footage, though I doubt it, as he clearly got bothhttps://tinyurl.com/4d7v8z29

content: Quote from: quince on November 10, 2024, 07:13:08 amThat subject with the specific measurement are simply to small to validate with a thermocouple, the purpose of that test, was simply the minute differences and alignment of the crosshairIm only referring to a Seek Compact Pro Fast frame version from 2016/17 which has been solid over the years, and you can get some nice relatively clean footage.That model... runs at 17 to 19fps.. you can get a small readout at top, if you activate the "easter egg" menu on iOS.Do like Seeks app and the ability to look the span.. primarily the colorpalette Tyrian.. that palette I used a lotThe footage I have seen so far of the Nano300 at times seems subpar of their older Compact Pro FF version but at least the prices seem to have dropped accordingly, and it could be down to lack of manual focus on these Nano... having manual focus goes a long way on a thermal camera, when you dealing with so low res and wanna use it in various situations...Some footage of the old 2016/2017 Seek Compact Pro fast-frame (FF) iOS model.A defect "Smart" 4S LIPO cell. (mainly one cell is highly puffed/gassed).. the other video is a 4wire cirquitboard for various battery-sizes attached to a programmable ET5410 sink load, and lastly our beloved cat, Victor.Its not half bad the footage you could get out of these Seek Compact Pro FF back in the late 2010sYou can get some pretty good details, as seen around the +1.10-minute mark.
