    You do not need full GREEN ferrite, it is for low frequencies.
    You need YELLOW/WHITE; GREEN/BLUE; RED/BLACK

    These Chiwanese tronics devices are great fun. The unassembled kits are just dollars and should be easily assembled. // I got the clear and translucent blue non-Dinky versions of the USB tester/VA meter for 2.13USD and 1.60USD, and they're very handy for troubleshooting chargers and cables, etc. // What a LOVELY water feature, Julian. // I still cringe when I see you hacking things open with that box knife. I use the little enclosed envelope slitters I got free from 37 places at COMDEX (back in 1998) and other trade shows. Checking Ebay, they're $4USD now! Ridiculous.

    You can buy all that stuff for very much less, purchasing them directly on Aliexpress. I've bought tons of crap from that site and became addicted. So much crap to buy.

    I ❤ my tester because it made building the other 8 kits on my bench so much faster. It would have been great if it did nanofared capacitors. That would have saved me getting out my bright light and magnifying headset to attempt to read the silly things. But not having to read the color stripes on quarter watt resisters made up for that somewhat. 😁

    Seriously, nifty tool.

    Hi
    Can you help me to calculate inductor number of wires, size etc for 50amp mppt. Currently I am using T157-26 x 2 Yellow White cores 12 rounds of 22 gauge wire 20 wires together like a rope?
    Problem is it is core size is small and winding (rounding) 20 wires is really difficult.

    Your USB dinky's display is defective

  14. Avataaar/Circle Created with python_avatars Richard Smith says:

    lmfao. Do they know 'dinky' is slang for poor quality?

  15. Avataaar/Circle Created with python_avatars Tony baloney says:

    After I saw this, I bought one of the component testers shown in the vid. Question; I have looked for software that you could run on a laptop. Input via USB attached to a proto board. Any ideas?
