Sir,
Its a nice video. I brought the balancing board. I tried testing the balancing board for verifying its regulation by connecting the supercapacitor and a variable power supply to the same slot and used a multimeter to measure the voltage of the supercapacitor. Not sure if the method is right because the multimeter would not be able to show the actual voltage of super cap as the source is also connected to same point. By this method, I find the voltage rising above 2.8V. Didnt check after that. Is there any way to ascertain that regulation is happening? What is the max applicable voltage to the board for the regulation to happen?
Hello Julian! 👍
That's very nice of Adam Welch, that he has given you a soldering station!
Not only did I subscribe to you, but also Adam Welch's channel – very interesting!
Best regards from Austria!
PS .: Yes, I know that this video is from August 2017, but I'm watching all 88 videos from your playlist!
I don't understand why you are so timid when it comes to the current setting you're using to charge those capacitors…
Here's a thought: How about instead of an LED, connect the input side of an optoisolator across those resistors. Then you can do all sorts of things with the output sides, and it won't depend so much on the exact details of the circuit you're trying to monitor.
My solder station the same unit burnt out after 3 weeks!
I ended up getting a Precision A55KJ!
RIGHT!
I like that little power supply you're using, where's it come from?
Hi, i like your video's Julian. Do you have a link for the small power regulated supply you used to charge those supercaps ? Thanks.
Sorry, found it …;-)
i love my katsu and i run it at 350 temp
You should make a capacitor based spot-welder for 18650 batteries.
Flux!!! It will make soldering so much easier.
You have a full chain of crappy elements with unexpected behaviour. No way you can seriously measure something and learn from it. I suggest to start with a decent power supply and a reliable reading of voltage and current. Never trust build in 7 segment 10 penny meters on Ebay DIY power circuit boards. 🤓
Can't wait to see this all done.
Julian how does the protection circuit work if you are charging directly on the + and – terminals
