  1. 14:10 for those who can't find 5 cascaded peltier module. Ready made 3stage peltier module costs 191USD https://www.digikey.jp/short/d0qvwn3v

  4. Hi, thank you for your comment! Could you please tell me which word miss pronounced? English is not our native language .

  5. To measure and evaluate switching waveforms of power semiconductors such as MOSFETs, IGBT, and GaNFET. Higher sampling rate and 12bit voltage resolution are very important.

  7. Hi, Using a temperature-controlled soldering iron is good solution

  8.  @frieddo  350℃±10℃ for lead and lead free solder. For bigger parts and large area copper pad 360℃ or more maybe OK.

  9. I use pc based scope like analog discovery and adalm2000 too. It works fine for low voltage and multi mega hertz measurement.

  12. Who will compensate you if your house catches fire and burn down due to a cheap battery malfunction? At the very least, the company selling the cheap batteries won't compensate you. Buying a brand-name product means you are buying peace of mind and safety.

  20. I measured a 1 kΩ ± 0.1% resistance using my jig, Kelvin clip, and two-wire measurements. 1.000098 kΩ with my jig 1.000096 kΩ with Kelvin clip 1.000202 kΩ with two-wire measurement. I did preliminary experiments between the Kelvin probe and my jig. There was no significant difference between the Kelvin clip and jig readings. So I found out that this simple jig would work fine for measuring 1kΩ resistance. Thanks for the comments.
