| When working with electronics, you always need one basic thing; power. This power supply is great for powering all kinds of electronic projects. It produces a well filtered, variable 1.2-30 volts at 5 amps. It is easy to build and the parts are realitively easy to find. |

| hi sir it's good power supply ckt, but i don't want to use transformer so please send me ckt that should not contain transformer but do the same operation as this ckt do. (Editor's notes: You need a transformer.) |

| hi....Good day!!! do you have an schematic of an inverter frequency, and it's article of the matter..i needed it on my project in school...or do you know how to increase the frequency of a power supply from 50hz or 60Hz in a computer....thanks for responding...i highly appreciated for your response...God Bless....just email me...thanks | ||
| This is for a Princeton Graphics 17" LCD flat screen monitor. I am electricity challenged and have no clue about using more or less...etc. Can either voltage of amp requirements be lowered or lessen safely and still function correctly? In other words, could I use a 12 volt 2 amp or 300 ma as a brief substituite? | ||
| Hello! i need the circuit of a power supply having output from 0 to 12 DCvolts. Its better that it is made up without using any IC,if not possible then send me the circuit with IC, and i want its full woking and description. Plz mail me as soon as possible its very urgent plzzzzzzzzzzzzzzzz! | ||
| i need the scematics for a regulator circuit that can be used to reduce the output of 2 3vdc batteries in parrallel. this is to be used to reduce the rotation speed of a small dc electric motor | ||
| I am working on a friends Tattoo gun power supply , very similiar to the one here but uses 2 regulators LM338K and a LM350k , my question is why the 2 regulators I think the guns don't draw more than 3 amps , he did a 5 hour Tattoo and it crapped out , looks like a resistor is burned out could you show me a diagram of how you would hook up dual regulators like the one I am working on ? Thank you in advance ... Lalo...:-) | ||
| Hi! My instructor told us about our requirements this final examination, that we are going to design 5-amp, 12v-0-12v step down transformer. i had no idea about the computation of the said transformer...pls help me or give me some idea on how to compute that transformer...hoping for your kind response... thank you and more power!! | ||
| Hello I need Power Supply with positive common of 0 to 70 volt 2 amp out put . Please mail me if you have this | ||
| thts a really cool circuit i really get sucess in the projec will u tell me the formulas relating the dc power supply construction | ||
| why is it the power supply connect to the12volts positive and negative? why is it the output of power supply of 6amps is 15volts? | ||
