  1. Also have a #thermal video of the FET dissipating 10 J of thermal energy over ~1 s while slowly charging 8 mF of capacitors up to 50 V :D

    It reaches a bit over 80°C, which is pretty manageable. The PCB is still free standing in this video, it'll probably be even lower while screwed to the contactor.

    (My #P2Pro is a bit borked after the years, it reports the temperatures a bit high (probably 5-10° higher than actual) and has a "colder" vertical strip, please ignore :P)

  2. Ausprobiert: Thermal Master P2 Pro – extra kleine Wärmebildkamera
    Wärmebildkameras zeigen ein Bild der Welt, das dem menschlichen Auge normalerweise verborgen bleibt. Das des langwelligen Infrarotspektrums. Damit lassen sich viele Dinge sichtbar machen. Zum Beispiel Isolierprobleme an Häusern. Aber au

  3. Despite the 2022 post (-> #GoodOf2022), my brain again fell into the trap of thinking we haven't accomplished much at all.

    So again, here's a summary, partly for myself, of some of the things I've achieved in 2023:

    - Bought an Infiray #P2Pro thermal camera module and reverse-engineered its protocol
    - Fixed #midiLighter deep-discharging the LiPo after a fault
    - Got started with #CH32V003 development
    - Tore down and partly reverse-engineered my #Storm2 powerbank

  4. Can anyone recommend a #framework that allows relatively easy cross-platform (#Android, #Windows, #Linux) development?
    Needs to be able to:
    - Open #USB webcam stream
    - Call #ffmpeg
    - Send USB vendor control transfers (or calls to #libusb)
    - GUI

    :BoostOK:

    I really don't want to write code two times (and dislike Android app dev), but recently realized that I'd really like for my upcoming #P2Pro viewer to run on Android too.

    But if there is no such thing, I'll stick to desktop only for now :/

  5. Thermally, it's pretty good as well. This is all LEDs on at full brightness. The driver is basically negligible in terms of heat. The LEDs reach around 50°C. Taken with #infiray #p2pro

  6. PSA: The Infiray #P2Pro (very nice #thermalcamera module) is currently on sale at Pergear DE: pergear.de/products/infiray-p2
    And an additional 5% off with the coupon "PERGEAR-DE2023".
    Comes down to 208€ instead of 250€.

    For more information about the camera and my initial #reverseEngineering attempts, click on the hashtag, or here's the link to my thread about it: chaos.social/@LeoDJ/1096330333

    Not sure, if that's too much like advertisement, but I really like the camera and wanted to share the deal ^^"

  7. Fursuiters in #thermal IR look kinda creepy, ngl.

    Pictures taken with the InfiRay #P2Pro thermal camera.
    Bonus video in the comments below.

  8. Some nice thermal images from #HackerHotel taken with the Infiray #P2Pro :D
    You can even see the image on the LED matrix!

  9. First I desoldered the connection to the MOSFETs, but the resistance was still low. So it wasn't the FETs.
    Then I applied power to the PCB and it drew around 2mA. Not a lot, but way too much for standby current.
    With the lid closed and the FETs disconnected, not much remains in circuit. Taking a look at the board with my trusty #P2Pro revealed the LiPo charging IC getting ever so slightly warm (about 0.5°C delta). Busted!

  10. Brain: "Hey, wanna model the InfiRay #P2Pro in CAD?"
    Me: "Not really, what would I even need it for? Also, shouldn't we go to sleep?"
    Brain: "Why should any of that matter? Here, sudden motivation. Wooosh!"

  11. Yesterday I've learned what USB filter drivers are on Windows and that it's apparently pretty easy to install libusb0 as one. (Thanks @patagona)

    Having done that, my initial plan worked on the second try. I can now send the command for switching the color palette, wohoo \o/

    I only needed to make sure that I send the USB control transfers after the video capture has already been started, otherwise the call to #libusb will just hang indefinitely for whatever reason.

  12. Ok, so the #Infiray #P2Pro appears to simply enumerate as a USB UVC device (webcam).
    You can just open the device and already get a pre-processed b/w video stream. That's cool, but not quite what I'm after.
    According to the USB descriptors, there is a second ("hidden") UVC frame type available, with double the vertical resolution.
    Changing to that resolution, there appears to be some kind of additional data in the lower half (raw data?) and VLC has trouble decoding the frame (it's twice as wide)

  13. Here's a video of running water.
    I didn't have that much fun just playing with water since I was a little kid :D

    Sadly the Chinese-feeling app drops some frames during recording, on my screen it was even smoother.

  14. I recently bought an Infiray P2 Pro #thermal camera module.
    It's quite the capable device: RTC2121W sensor, 256x192, 25Hz, -20-550°C, 50mK, ~230€.
    You can clearly see the different efficiency of my 4 monitors.
    And the comparatively high frame rate makes for some stunning videos (see below).

    I'll also see if I can access the raw data myself.

    Good review and #teardown video from Mikeselectricstuff: youtube.com/watch?v=YMQeXq1ujn
