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.
Great project, can't wait to get my part in and give it a go. One comment though, I would suggest that best practice dictates you do not screw to the back of the box. The enclosure you are using is designed to be used with a steel back plate for mounting your equipment to.
great video and everything explained very well, but I would always attach ferrule connectors to the cable ends, this is simply the cleanest and safest option
Great video Gaby. I would really appreciate and request a video on how to hook up the transformer to the switch and mains. That would really help us noobs close the loop on UCPure.
he video shows the transformer output connections for the input depends on your city voltage see this Pdf for the transformers I am using bottom of first page connections, or the specs of your transformer www.mouser.ca/datasheet/2/410/VPM24_2080-844679.pdf
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.
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.
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]
hmm, Would be a good idea to use Rock wool to lined the high voltage areas/contacts as shield incase it blows it won't catch on fire at least buys you time.
How do I connect this to the streamer from your previous videos(without the DAC)? The streamer I built from your awesome guide only has two terminals powered by PurePi and ucConditioner. The one in this video however has three(+5/0/-5v).
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.
Great! Wow. Look forward to see it with the dac. Can you also suggest an easier way to power the dac? Would like to build the dac, but am not sure about building the powersupplies. Thanks for great videos. What are the w x h x d in cm of each build?
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.
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 :-)
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.
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.
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.
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?
yes a bigger house would help it is possible but that is too big also they are only good for devices that do not consume a lot of power as they run independently from the power supply

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.

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.
