  1. sorry we have been talking about differnt things that is a regulator with rectification. the 4 cylindrical shaped objects on the bottom left are diodes. you can supply that board with either AC or DC depending on what you have available.
  2. so they say its meant to "replace" another voltage regulator like the lm317 etc but realistically that item is the entire circuit?
  3. I cant quite see.. .does that regulator have the adjustment resistor built in to be able to set the output voltage?
  4. the regulator pcb that has been referred to by everyone is this one Super Regulator V2.3 - Power Supplies and Accessories - Circuit Boards somebody wanted to know if they could use the belleson super regulator chip in this design but no you cant
  5. the reason i started to design my own regulator board was i didnt want to have so many individual power supplies for each component. as it is ive got 2 per PC and i want to power separately : mobo, cpu, PPA usb card, 2 x SSD's, 3.3v pcie, neutron star clock it would be an excessive amount of boxes but with regulators i can put all the boards inside the chassis and just have one external box with a couple toroidal power supplies in them
  6. they would not work "in that design" The adjustable voltage regulator circuit is much different from the BJT design used in that pcb. Have a look at the circuit diagram on the DiY audio store page and in particular Q1 and Q2. that is where somebody would try replace the transistors with voltage regulators and the circuit to make them work properly simply doesnt exist in that design. there are many simple designs in which they would work but this isnt it The belleson super regulator needs a resistor on the adjustment pin to set the voltage which doesnt exist on the pcb.
  7. i only became interested in this stuff a month or so ago - only reason i knew the jung regulator wasnt right from the start is i already looked for options to do exactly what you are doing! let me give you one peice of advise: do not ask for help on a regulator on DiY audio and tell them its to separately power computer components. all that they will do is tell you that you are an idiot. (i can tell you that from experience)
  8. that is a completely different design! the belleson unit is a voltage regulator to replace units like the lm317, lt1083 etc the jung super regulator uses transistors to regulate the voltage so you cant simply use the super regulator on that pcb.
  9. the current rating of that super regulator is like 200ma its a no go for your requirements.
  10. you can see a graph that lists the ripple on the data sheet and various frequencies. im sure you can find an equation online that will help you the one thing i cant find is the noise rejection and what frequencies it works on
  11. the lt1083 seems to be as good if not better... it has higher dB voltage ripple rejection and the rms output noise is .003% which at 12 volts is 36 uV please feel free to correct me on that if i am wrong
  12. if you need something with a little more power the LT1083 has up to 5 amps and it also supposed to have much better noise rejection than the lm317
  13. ive never seen a commercial grade IP phone that doesnt have a port in and a port out. how else can they sell phones to companies that only have one data point per user? large existing companies would have to pay a fortune just in cabling costs to migrate to ip phones. its either a 100m or 1gb switch depending on the phone. and the router i posted has 1gb ports if that is the one you went for.
  14. please dont recommend a pi2 for a novice!! i agree with the rest though - kodi is an excellent media server. you can use a standard computer with a couple big hard drives in it and the handbrake software for cd ripping
  15. the mikrotik has so many options you will likely be as dumbfounded as i was when i first logged into one
