    Red Cells with NJTM4E9 on them?

    Hey! You're right, I just looked at them in the sun and I can see the SANYO UR18650FM! I would have never seen that if you didn't mention it. :thumbsup:

    Red Cells with NJTM4E9 on them?

    Here is what they look like, the second set of numbers under the NJTM4E9 looks like serial numbers, as they are all different on the cells

    Red Cells with NJTM4E9 on them?

    I pulled 8 cells out of a dead HP laptop pack, and I can't find any info on them. They are 18650 size. Has anyone seen these before? - Mark

    Finally! A $20 USB logging luxmeter

    That is a great graph showing the limitations of the meter above 20k lux. Are there any artifacts that you can find on the lower end? I'd be curious to see if the zero point could change with temperature. I don't have any experience with lux meters so I find this fascinating.

    Hexbright Open source flashlight

    I know this is necro, but I have a question for anyone that still has one of these. Does anyone know how to get it programmed on Windows 10 with the new Arduino IDE? I am having a difficult time getting it to work, even with an old IDE.

    Sold/Expired Anyone have a Hexbright?

    I have one. An original in Green. I don't think I can get PMs yet though, as I am new.
