 :-DD But of course, haven't you seen me say I don't have a stupidphone!?

That one says right on it that they are hard to come by.  ;D'

What it does not say is that they are all designed for one specific purpose so you can't use it for something else.  ;)

Humble apologies about the misunderstanding. I had taking the liberty of presuming that "I don't have a stupidphone" was another take on the "my home computer's BASIC is better than your home computer's BASIC" - ie you choose something you consider to be cultured and sophisticated, like (and here I take the risk of being downright insulting) a Windon't Phone, as opposed to one of the varieties of fruit or mechanoid-themed devices.

I've just phoned out for a pizza with a side-order of humble 3.14159 (or, perhaps, 8.53973422267).

Rubber bands bridge the gap between WD40 and duct tape.

Oh, gee, no offense at all!  I call them "stupid-" instead of "smart-" "just because", for the irony of it I guess.  How often do we refer to our computers as "stupid computer"?

I tell people that the PI Zero I mobilized to use for driving a Seek is like a smartphone without the phone, or a "smart".  I'd keep the same vernacular & call it a "stupid" but I am too happy with how it worked out to call it stupid. :)

Just for documentation the changing image quality when cooling a CompactPro.
Not to be confused, the CompactPro was pointed to a "normal" Seek Compact plugged into a Motorola G5s. The CompactPro is connected to a Sony Z3 with the Seek-App version 2.1.6.

At first the CompactPro was running a few minutes, then the recording was started and the screenshot on the left is showing the image quality. There is no significant change in noise before or after the NUC (or FFC  ;) ). Then a small piece of water ice wrapped in a paper towel was put on the case of the CompactPro behind the FPA. The case is slowly cooling down a few degrees and the image quality is changing significantly. Much less noise but only shortly after the NUC (middle screenshot). A few seconds later the noise is even worse than witout cooling until the next NUC.
You can watch the recording in realtime here: https://files.catbox.moe/hcyhro.mp4

When I get a round tuit  :blah: I'll put the CompactPro into a climate chamber and check if the noise still changes when having a constant temperature.

My normal Seek Compact does not seem to improve with cooling, at least there is no visible effect.
On the Internet, nobody knows you're a cat.

Beware using 'noise' as 'spatial noise'.
To reduce the residual spatial noise you need to stabilize the temperature, not cool without any control.

Всем доброго времени суток!
Ребята подскажите, умеет ли Seek SHOT PRO снимать макро, к примеру рассматривать с расстояния 5-10см платы например смартфонов ?

Nyet.  See the first line from @blueskull here: https://www.eevblog.com/forum/thermal-imaging/thermal-camera-lens-mod/msg2518086/#msg2518086

Seek Shot is "fixed focus" (aka never-focused), so it would need an added external lens such as the ZnSe lenses many people use for that purpose in order to get a closer focus.

And, yes I used Google translate.  Ya ne  ponimayu russkiy.  :(

Today I got the actuators. I tried connecting the first to 5V and nothing happened... Then to 10V nothing... 20V, 30V, 40V, and then it started to smell...  ;D

Went back to 5V and swapped the leads (red to - and black to +) and "click" it changed the filter. Swapped leads again and "click".
So every time you want to switch filters you must change the voltage polarity.

The smallest actuator is just perfect for Seek. I will be swapping its filter for a painted copper/alu plate in the near future.





P.S.
Fraser big thanks for pointing me into this direction. :-+

Hi,
This can be soldered directly to use power contacts from existing shutter? Or seek's voltage is too weak?
