I Love Analog Meters!! I can watch them all day. Thanks Julian! And Thank You for the first video I saw. The Breadboard Arduino. Yes, I did buy an original as well, and donated $50 (US) to the creators. The Arduino community is indispensable! Thank You to all that have contributed to the hardware and the software. (I know, this tutorial is not really about Arduino although, you are using one!!) :-) Thanks Again, Julian. You are an ICON! A DIVA, if you will. Rock Star.
I may have missed it somewhere along the line, but what's the plan behind these SuperCaps? Are you planning on filling up the air raid shelter with them and then discharging them all through the washing line to act as a Sparrow deterrent that replicates sonic booms???
Re: croc leads: If they are the same as I got, and that's very likely, they are absolutely terrible. Aluminium wires, and they are not soldered to the clips. Resistance value is very high. You can identify them by how hard it is to open the clips. They are super slippery and don't want to open.
I didn't hear any high pitch sound, but the microphone did pick up some noise (unwanted disturbance). My guess it is from the magnetic field of the inductor.
Julian, what would happen if you replaced that toroidal choke with a transformer? Edit: Like, if you wired it right, could it make a buck boost converter using transformers?
I thought everyone could hear up to15000hz. I used to be able to hear up to about 25000hz but haven't done any test for years now I'm not sure about the speakers I am currently using though what their frequency response is.
rimmersbryggeri there are many factors like age and what your ears have gone through. Not to mention like you said your speakers. Above 50 years old it can drop below 12khz.
Would it be possible to find a similar superCap and replace the lazy Cap so the superCap module balances faster, thus the rest of the protection circuits don't heat stress the other caps ,and should reduce the premature failure of the other Caps due to the heat ? Great video btw.
Thanks for that, but I meant the capacitor board the one that takes NINE supercaps? How did the lazy cap exercise go? I made a block of 8 by 8 caps for a solar stabiliser, guess what ONE in the bank was leaky... Finding it was tricky with 8 parallel rows...
The paint would be a lot more interesting with a couple volt meters. Analog ? Ok , if you must, but those little meters from Lucky Warm are also very cool and use almost no current , 3 or 4 digits. One green, one blue or red, well , one at the input, one at the mid section, and one at the 24v section. Would make watching paint dry a lot more interesting. You would think the second mosfet would be using more current ? No way to really know except for burning your fingers ?
Hi Julian, I missed the reason for the 9 super caps, what do you intend to use the pack for? and have you got a link for the nice regulator board ? Thanks.
Julian, Wanted to let you know I really enjoy your videos. You teaching me to order from ebay has created a bit of a monster. At least the electronics are not too expensive and it is fun to do. 🙂
Hi. I see you use jlcpcb. Could you please tell me tell me if you use a app to set up your component layout, or does jlcpcb has its own app on their website. If you used a app. What app do you use. Thanks jon

Love watching paint dry.
I find your commentary and thought process helpful. Keep up the good work
@11:45 Use your multi-meter to measure the voltage across the wires between your buck converter and the capacitor.

Never has such complicated circuitry been used to dim a lamp!! Is there a point to it all?
Ah, but how do you brighten that lamp?

Yeah, I've got lots of those :(
Well, that's why I bought the crocodile clips separately, and banana to banana cables. It's also much more versatile.
did anyone else hear *really* high pitch noise 3:20 and almost every other time he surpass 2A?
I didn't hear any high pitch sound, but the microphone did pick up some noise (unwanted disturbance). My guess it is from the magnetic field of the inductor.
you could add a hall effect current sensor to the arduino for constant current mode

Even if he linked the secondary of 12v transformer to see if generate 240v pulses just for fun
Your shaft needs a nice big knob on it for fine manual control.
rip my ears
yup
Nice length video Julian, my paint now dry so on to next job, ta!
Julian Ilett. More interesting than watching paint dry!
Wouldn't the inductor have influence on the meter coil ? Being an inductor itself.
My poor ears, at about 5:00 the frequency shoots up. Just a warning if you have that range of hearing. It's like a CRT.
Sorry, I forgot about the 15kHz :)
@@JulianIlett no worries, it happens.

@@CuriousGamer83 I don know that. I kind of messed up my mid range with loud music when I was in my teens and before that ear infections.

Can you add a constant current module to the board?
It should be possible to put a current sensor on the Arduino and build a feedback control loop to keep the current constant.
Do you have a link to those croc clips plz :)
Why, do you need ones that are especially terrible?
@@Basement-Science I thought he said these were ok ? ... I'll have to re watch :D
Are you going to use the Arduino to automate the current control? Seems the next logical step.

Ultimately, I want to transfer energy between two supercapacitor banks - first in one direction, then the other. PSU is Ming He B3603.
@@JulianIlett is this an end goal? why do you want to shuffle energy back and forth?
That's it, more videos like this :)
Julian mupping around I see......Loving this content.
Hi Julian, why not incorporate the two opto onto one PCB, wouldn't it be cheaper to build and easier to configure and operate?
Hey Julian where could I found Your code for muppet?
Julian Ilett for King.
Half a volt difference at 500ma is 1ohm of resistance, sounds like you got some shoddy connections or thin wire.
How did you address the cap reversal you were having in your first tests?
still using that nano with an identity crisis eh :-)

I use easyEDA and JLCPCB
use 2x heatsinks out of a broken HI-FI amp and use 5x IRF250 per heatsink
I believe i can hear the switching, sounds like 16khz (I’m 27 years old and can hear roughly to 17khz before dropping off)
You should add a volt meter in the output and feedback so the arduino can provide constant voltage
It's time to play the music.
It's time to light the lights.
One flaky cap out of a batch of nine, chinese factory seconds disposed of profitably by way of ebay! :-)
I'm the first view!!!
