- In this Video I show how a prototype of a smaller +5v 0 -5V and how long 600F Ultra Capacitors can last. This is a real world example showing how 1 min charge powers a preamp for over 1h and a half or longer.

What was your previous DAC Sheldon?
Thank you Sheldon for sharing your experience nice to hear a independent person that built this also if you let us know your previous Dac it will help us a bit more.
Thank you for sharing nice to hear your take.
One day UC's may become a replacement for chemical reaction batteries, but more work needs to be done to increase its energy density. Just imagine charging up a 1,000 Km range car in 10 minutes FULLY, not that fake 80% like EV's today.
@@naren.freak1cI’ve had several including pecan pi 1, topping d90, and a few others. The pecan pi is a great value and great sound. Topping d90 measures incredibly good and of course sounds good. Somehow, unless I am just fooling myself, which is possible, the Ian Canada rig is a clear improvement. More depth, separation, kind of more everything. At some point I want to do simple measurements just to see if there isn’t something going on with a boosted presence peak that is causing me to think all of this.
Hello, We have seen your experiments with the big old Philips chip which is usually improved by decoupling caps physically mounted next to the TDA chip. Next step would be replacing lower grade caps by better ones. Of course these tiny caps dont contain any energy and just there to add the last bit of filtering. Especially if you need to put caps in series to achieve higher voltage rating you will end up with a cabin luggage volume/weight of caps ( not sure if it can go through security check!) Bigger items will introduce longer power supply cables into your build.. The latest boards will allow you to charge during brief moments of time when no music is playing so you might as well use smaller caps and reduce the cables with 80% or more. I know there are higher voltage ultracaps '' units '' which are made by the original manufacturer. These already contain the balancing circuits and will allow a more compact build. Greetings, Eddy
I’m so glad you did this. It’s so helpful. 😊
Thank you Tina appreciate the support 😊
That is great been wanting a smaller and cheaper alternative Hopefully Ian will build one. Great suggestion.
As always, it was a great pleasure, thumbs up
Thanks again 😊
I was really hoping that you would do this... Thank you.
My pleasure!
Thanks again
Watch out for April 8th.
Thanks!
Thanks a lot for your support it means a lot
Thank you that is exactly what I was looking for the big drawback of the Opa861 is using the 2 massive banks of UC's something like this is ideal and the fact that it uses only one power supply not 2 I hope ian will make something like this.
Hello, Is the Opa861 good enough to justify buying 3000F instead of the smaller ones. Maybe better get the output transformer module recently released
Hi Gaby, nice idea, thanks ! What is actually the "too high" consumption of your charging module (roughly, in mA) ? Does it take current from the super caps - that would limit their real autonomy ? Because if it is only on the power supply side we don't really care, isn't it ?
FYI I designed myself a 6kF 3V supercaps charging circuit based on a Schmitt trigger (set-up between roughly 2,80 and 2,98V) and the leakage current on supercap's side is a couple of mA only. In any case, pls keep us posted !
hello gabster! big thumb up for your videos! i m wondering if this ultra capacitors power supply could be a good idea for valve tube preamp???
Not practical for high voltage you will need a suitcase of them
Gabster, your videos are now on top of my "must watch" list. Wondering why you didn't use the Ian's UcConditione MkII 5V?
It does not regulate or control the charge also always connected. You need a 10v or maybe a 10.4 UcPure Mark III Hopefully Ian will create one, not so hard for him as he has done all the research just need to change the voltage and integrate it.
i rarely comment, but i really like your videos, keep it up :)
i was also waiting for some ian canada conditioner alternatives, how you like the sound of the chinese ultracapacitor boards compared to ian canada?
It is the capacitors you are listening to I doubt the balancing board has much difference
I was wondering if it would be possible to create a super capacitor power supply, inspired by circular breathing.
Two super capacitor channels where one side receives the input while the other delivers the power. When the power side is running out of power they switch
Cool idea not sure if the switching will cause noise I guess it depends on the load
I was wondering if you could use those balancing boards intended for 6 ultracapacitors with less than 6 ultracaps - like 5 for a 12v (and -12v) supply I need for an AD1862 DAC build.
If your load is 100ma or less You can in someway add 1 more and bypass the number 6 if your load is constant you create a timer relay that charges them at say every 1 hour for 1 minute add a fuse or what ever you think you need
You will need to check and measure
Also check the linear pie you can configure it for 12v
If you are advanced you can go inside often the 12v splits in 5v. And 3.3v then feed individually and bypass the 12v lots of ways 😊
Hope that helps
@@Gabster1 thanks for the detailed response, Gabby. I've built my own LTO battery + supercaps supplies I float charge with a relay system plus current controlled buck converters controlled by Arduino so they disconnect the charging when music is playing. This works well for +/-5V and -15V for my TDA1541v DAC so I was hoping to do something similar with +/-12v to see what I can wring out of a DIY AD1862 DAC.
Hi Gaby, do you have any idea why Ian's UcPure boards need a minimum 3000F capacitor connected? I'm also looking to build a +/-15v SC supply where the input is isolated when not charging, but I would need less than 200F to use my system for 2 hours as it's only running a few opamps, so would save $$$ on SC's. Could you ask and or try and see what happens? Thx, keep up the great videos.
For 15v it is easy just use a UcPure III you can configure it to 15v and for balancer use a similar one to the one I am using here got a link for one in the description
For +15v- just build a second one see my video from few days ago to get a idea how to connect them
I would use the 3v 600f as in series they become 100
I believe Ian is working on some new boards and I can see a +\-5v in the short Horizon and maybe will nag him to do a +\-15 😊
I’m clear about the way to do +/- power supplies and saw that the UcPure 3 has 15v capability. My question specifically relates to Ian’s note in the manual that the minimum size of the super cap needs to be bigger than 3000F, but I don’t understand the relevance of that needing to be that big.
But rather than blowing up USD170 of UcPure boards to find out it does matter, I thought to ask the question. So are you saying that it’s fine to use smaller super caps? (Ignore the 3000F minimum) and use the UcPure 3 to do the on/off charge switching of 6 x 2.7v super caps and do the balancing with another board like the one you used?
Hello, Ian's main target is selling as many boards as possible. If you use smaller caps you will have more money to buy a higher quality dac like the dddac . 3000F is chosen because of more impressive specs. They can run longer without charging but with " intelligent charging " this is not really an issue. Other specs get less importance if the supply will be located at a greater distance. Giscard if you are French try to find Jean Hiraga prepre named Autographe and read his ideas about power supplies. Greetings,Eddy
@@edgoewie2132 Hi Eddy, yes French name but not French 🇫🇷. Ok, I didn’t see why the 3000F was important other than with Ian’s balance board that only fits that form factor. I’ll get some UcPure III boards and see how it performs. From my calculations, the circuit draws 120ma, so with 12x 500F (6 per pos and 6 per neg supply, it should run in excess of 2 hours. Plenty long enough, especially when charging during mute sections.
I do not have any issues running smaller UC's
I even run my 5, 200f hybrid caps that is 40F in series see my tda video. I don't know why but suspect to have enough reserve also bare in mind the voltage starts at 15 and start dropping till 14 something, so bigger is better to benefit from the charging between songs and maintaining as close to 15v as possible.
so just to be clear, we can take any identical 5v PSU connect a "+" and "-" and have a 5, 0 and -5 v right? I ask this because I am thinking using a Jcat Optimo dual linear PSU to convert it from dual 5v to a 5, 0, -5 , and 1750Euro is a lot of money to blow up in smoke. As I said in previous videos, the clocks need to be stable, and charging and discharging capacitors or batteries does not provide that. I know Jcat do very good linear PSU and that will keep the clocks run at the same voltage for ever since I do not plan to power off the dac. I will email Jcat and see if they can build a unit for me, since they build to order anyway.
They need to have independent power supplies
In order to connect a plus to a negative
Or like here taking a center tap from the middle.
And depending on your devices you may only power 1 device like you may not power a opa 861 then use one of the 5v to power The FIFO need to be careful with ground that usually is shared or not shared.
Bare in mind with Ian’s UcPure mark III they charge for a second between songs that helps the voltage more steady
I'm planning to do an Ian streamer and only want RCA and Optical. I think I need the 20B Transport Pi and would upgrade to his SC clock. I'd like to use his power supply in this video. With the 20B i'd like to nest the minidsp nanodigi. I'm wanting to know what I need for the power supply please.
I may want to also include two of Ian's DACs 2way speaker system. Again I'm not sure what to include for power supplies.
Is it mostly important to have his SC-Pure clocks in the streamer? I think so, and hope so, as I don't really want to add 6 SC-Pure clocks for this build.
I mssaged this way to help your channel out. I look forward to as clear a comment as you have time for. Thank you.
Why not build something like this simplifies power
DIY Audiophile music Streamer for a Dac with Flagship HIFI parts from Ian Canada upgraded Part 2
czcams.com/video/7w8dD573e9M/video.html
I would use 1 Dac for a 2way if you really want Bi Amp as you may get timing and phase shift issues
What was the previous DAC of the viewer?
exactly what I was about to ask.
I added a pined comment on top you can ask him as a reply and hopefully he will reply
@@Gabster1 thanks, i ask on that pinned comment
Hello, the most important line to remember : " it is not very practical " .
Regenerative power plus lt3045 combo can be much better!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ultracaps are not the best choice!!!!capacitors are not the best choice!!!! Regulator is the best choise!!!
this guy not complete by the full experiences!!!!ultracaps just secondary option, dangerous, and not comfortable to use!!!!!
