Hi, I am new here..
I want to ask lot of suggestion from u all.
I want to design a digital instrumentation circuit that contains DSO, logic analyzer, and a spectrum analyzer. Is there anyone here that can help me from where to start. I am really focusing on designing one by one first. But can...
lm317 power supply
Hi guys, I want to ask u all about what i am doing right now. as far as i can see all LM317 circuit will never produce a 0 volt minimum voltage if u take the volt from the voltage output pin.. I have try to adjust the output. i take output from the Adjust pin of LM317. so i...
AC Power Supply
what about making switching variable AC. as an example, maybe we can set 3 , 6 and 9 Vac. then we use switch to change between the ac value... can it be done?
dc-30v
thanks very much for that tips, can u help in giving any basic circuit for designing the circuit for that.. it is really difficult to build one my self..
variable dc 30 v
no... if we want to design a power supply that can produce variable ac voltage, can we use regulator? i guess it was totally a different circuit.. maybe need to use thyristor.. i really need help on that.. designing a variable 0-30 AC voltage supply.. anything similar can also...
Re: AC Power Supply
can i have your example circuit for the variable dc circuit??
i just want to see as reference.. me also also having the same problem with u..XD
variable 30v
thank you very much for your help.. that really helps a lot.. :D i also need to design the variable ac voltage for 0-30 Vac.. do have an idea for that? basic one.. i maybe use the 240/15 v transformer..
Hi guys.. I need help from u all profesional designer..
do u have any design of a power supply..
the voltage from 240 Vac to transformer 18 V Ac.
i want to change the voltage using lm7815 and lm7915. it for +15 V and -15V.
can u give me a design circuit for this circuit.. any simplest design..
Analog Trainer
hi guys..
i want to build an analog trainer for secondary school.
can i get any advice from experts like u all.. thanks a lot..
my trainer need to contain resistor, diode, capacitor, inductor.
if can, i also want to put transistor and amplifier. it will be trainer that can use...
