    Trying to troubleshoot DDR4 SODIMM slot with slot tester
    by Lifeisfun
    Hi folks!
    I have some kind of memory problem on Lenovo laptop. I was initially able to install windows after several tries since the laptop did freeze in middle of those attempts.

    Reverse engineering of 18650 4-channel tester
    by spleenharvester

There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board...

    I got this device yesterday and did some testing on some tabbing and some incandescent light bulbs and it seems to work very well from what I can tell but how do I know how accurate the m-ohms section is what can I use to verify it accurately I also tested some li-ion battery cells and this seems to be fairly accurate because I have another tester and they seem to agree with each other

    I also checked some capacitors with it that were brand new and seem to show about what I expected to see with my blue capacitor tester so I think it...
