I know that Mouser and DigiKey probably wouldn't send you charged capacitors but I always insure that any capacitor has been discharged before I do much more than pick it up. It is probably more relevant if you ever need to "operate" on one of your power supplies that have previously been in service.

@hommerdalor6301 4 месяца назад

Hi Gabster. Here are some of my ideas: Put spacers between capacitors, the zip ties will self pull from shocks. No washers between board & cap would mean less resistance inconstance for easyer balancing. Tin solder as about 6 times the resistance of copper, so I flaten the wire to completely cover the soldering pad on the board, no round wire just stuck like that protuding as a dog sht on the side walk. :-D Don’t touch with bare hands any surface or wire which will be soldered, clean with alcool, use flux, dip the wire in it, pretining the surfaces before soldering makes it easyer. Cheers.

@Gabster1 4 месяца назад

Great Ideas will help for sure specially flatten the wire to completely cover the soldering pad. note the washers are needed or the balancer will touch on the back and short. need that bit of space. I tried without and it was touching.

@DrHarryT 4 месяца назад

Maybe I'm missing something... Seems like a lot of expense and hassle to get a 6V-3Wh stable DC supply and when you only charge it to 5V you get .1665 less Wh. [lose 1/6th of the storage capacity and the voltage drops too during use] Better to use 2 Li-Ion batteries in series with a BMS that you disconnect the charging source for purity and then take the output and send it though LM7805/LM7905 positive and negative linear regulators respectively which will also maintain purity and will maintain a stable 5V throughout the much longer storage capacity of the batteries. [Don't forget the decoupling capacitors]

@sulaimanabdullah952 7 дней назад

The heatsinks on the pcb are to dissipate heat, mainly by convection. If you have no ventilation you will slowly cook your capacitors. If the connecting wires between the capacitors and the load (dac, amp etc.) are more than a few inches long their inductance will nullify any benefit of ultra caps, at high frequencies. Imagine the path that current follows, and make the enclosed area as little as practicable. eg two parallel wires have much greater self inductance than the same wire twisted.

You are correct the lid is spaced by 1/4 inch from the box and the wires are typically short in my D11 Dac they are about 4inches twisted

Hi Gaby, thanks for this great & detailed video, always very pleasant to follow and inspiring ! One comment / question : concerning ESR in my understanding it is the one seen by the final application (DAC, Streamer ...) that counts. Thus I don't understand why you so much carry on lowering the connection resistance between supercaps and Uc Pure and then use smaller and longer cables (the three colored ones, with obviously higher resistance ...) for the connection to the end device ? I also built such a supercap 3V3 supply for my Ian Canada I2S Streamer but shortened as much as possible the length of this final connection to a couple of centimeters. Btw ... I love your cats, I saw you have at least two :-)

@Gabster1 4 месяца назад

You are correct you are suppose to keep the wires as big and short as possible Often in my videos I am experimenting and I am using long wires but for the final product I always use a very short one. Positioning everything becomes challenging see my D11 Video.

if you want safety, make a copper bath with oil for each individual cell, and if you design it well it can outstand even an explosion. 😂 I mean most of those things are probably safer then what we buy since are done by enthusiasts and that means put care in what they build, since they build it for themselves.

@edmaster3147 4 месяца назад

What is the Theory of Operation for assuming that an Ultracap powersupply would be benefitial to an a/c fed quality power supply for a digital source? Always interesting to understand the thesis. And what the disadvantages would be. I have built very clean 12v PSU's, fast regulated with a feedback circuit. On these PSU's there is very low capacitance in the main caps (relative, its 1000uF bipolar) and a good MosFet is used for feeding the streamer. The idea of the setup is that the transformer and main caps are delivering a small, relatively constant current to a about 8w streamer. This setup works really well and is executed well; measuring noise made me aware of an illegal AM station in the neighbourhood.

@@Gabster1 Thank you. I have read about 7 pages into that discussion but failed to find any reference. It seems to be a discussion between enthousiasts. I've read a bit about use cases of ultracapacitors and behaviour, the impedance seems to be non-linear and in the DAC use cases still would very much need regulation. The myth about that audio devices sound better when battery powered is debunked for ages; they don't. Are there any known reviewers who tested PSU line-ultracap between devices?

@nickolaymiltenov 4 месяца назад

As much as i know ultracapacitors have slower discharge time than normal ones. So are they really suitable for this task?

@Gabster1 4 месяца назад

they are great for devices that do not consume a lot of power as they run independently from the power supply. They can discharge a huge amount of amps instantly so not slow at all.

@jeffschroeder4805 4 месяца назад

Just as a 5 gallon can takes longer to empty (slower discharge time) than a 1 gallon can the rate of discharge of the capacitor or gas can will be mostly dependent upon the impedance of the circuit in either case.

respectfully among many facts that most including you are unaware of is that there are induced self noises generated within the use of ultra capacitors. I have power supplies that I have built that easily outperform the best of what ultra caps can offer. Just the facts from a worldwide patented inventor of several advanced technologies. That's the difference between hyping technologies versus true best of class performance.

Ultra capacitors, like any other electronic component, can potentially induce noise into circuits, but it depends on various factors including the design of the circuit, the quality of the components, and how the ultra capacitor is integrated into the system. Here are some factors to consider: Switching Noise: Ultra capacitors can experience switching noise when charging or discharging rapidly. This noise can propagate through the circuit and affect other components, especially if there are sensitive analog or digital circuits nearby. Impedance Matching: If the ultra capacitor is not properly impedance-matched with the rest of the circuit, it can create reflections and noise issues. Proper decoupling and filtering techniques may be needed to mitigate these effects. Electromagnetic Interference (EMI): Rapid charging and discharging of ultra capacitors can produce electromagnetic interference, which may affect nearby circuits. Shielding and proper grounding techniques can help reduce EMI. Quality of Components: The quality of the ultra capacitor itself can impact its noise performance. Higher-quality capacitors may have better filtering characteristics and lower self-inductance, reducing the potential for noise induction. Layout and Grounding: Proper circuit layout and grounding are critical for minimizing noise in electronic circuits. Careful consideration should be given to the placement of the ultra capacitor and the routing of traces to minimize noise coupling. Overall, while ultra capacitors can potentially induce noise into circuits, proper design, layout, and integration techniques can help mitigate these effects. It's essential to consider the specific requirements of the circuit and the characteristics of the ultra capacitor when designing electronic systems. Testing and analysis may be necessary to identify and address any noise issues that arise.

@gherbent 4 месяца назад

Pretty useless setup. Is just for fun. Why not to use Li-Ion or Li-Titantate batteries instead of capacitors? They can keep a constant voltage for very long and use a pure analog voltage stabiliser instead of a switching one. Anyway I consider this setup pretty useless as many DACs and other devices will have internal switching power stages anyway, adding to that that you keep a charger connected to it anyway. I use a Li-Ion power source on my oscilloscope when I want to have a guaranteed voltaic isolation for measurements. In my setup I have found that the biggest source of noise by far were my Power Amplifiers either analog or digital, giving a constant 'hiss' in speakers even when the amplifiers are powered directly from a Li-Ion battery and disconnected from signal source.

How would you find enough resolution in the analog domain of the USB connected DAC? I would think that a regular correctly terminated spdif would be perfectly capable for audio signal where 48khz and 24 bits are far exceeding true performance of almost all DAC's - consumer and pro. It is my assumption that not the clock signals (bit/word) are troublesome, yet the analoge performance of those lines.

The point was to stop wasting money and time with linear power supplies, worrying about ridiculous jitter and all the crap the industry and peddlers wants you to believe... The point of using USB in async mode is that the DAC will receive the data in its buffer memory and then use its own local clock to generate the analog signal. And unless a seriously broken DAC, the internal small clock jitter is just noise well below human hearing threshold...

@@guyboisvert66 I can assure you, that I'm not mixed up, by no means. USB is a complicated solution for a non existing problem, in case of DAC's. A good USB does not make a DAC sound good. HiRes is absolute nonsense. It is really hard to get a DAC to put out even 14 bit, most devices, many popular included, in praxis reproduce hardly 10 bits and sound absolutely awful. Over here we are playing around a bit with Opamps with slewrates of 1200-1400v as I/V convertors, as most common DAC chips have a built in I/V conversion which is quite harmful. For instance, I'm experimenting with the dilemma, are the disadvantages of differential less than the advantages of single ended? It seems, but the simplicity seems to win in praxis.

@guyboisvert66 4 месяца назад

@@edmaster3147 HiRes is just a buzzword used by peddlers and the industry... More bits and higher sampling rate have their place at studio while recording and mixing. For playback, it doesn't bring anything, 16 bits being more than enough and having a noise floor much lower than human hearing capability. As for DACs having high performance in term of bits (noise floor) and performance, that's not hard to find these days: It's a well mastered engineering field. All is a matter of design going along with imposed constraints (price, marketing, component availability, time, etc), good results comes with good engineering.
