Re: Meddling with USB
i advise you to use FT245 from FTDI chip.
it is a parallel to USB converter. you could find sample circuits and free drivers from the FTDI's web page.<p>-Erkan

Re: voltage selector
Dale, Thanks for your helps, i did a simulation and i found the values as drawing below. for 12V, the output voltage is 9.791V. it could be harmful for my converter. because it was designed for 12V +/-%5. 9.7901V is very small for it. what is the reason of voltage dropping? is it possible to increas...

Re: voltage selector
Dale, i am waiting for your post and i want to remind something. when the input is 24V we don't need 34mA base current for 5A because when the input is 24V it will be forwarded directly to output. i mean Q1 is off. but when the input is 12V, Q1 will be on and the collector current will be 10A max. s...

Re: voltage selector
hello Dale, i have tried to draw schematic as you explained. i want to learn if the drawing is true. also are the resistor values important? thanks,<p> http://s01.imagehost.org/0332/selector2.JPG <p>[ November 04, 2004: Message edited by: yigiter ]<p>[ November 04, 2004: Message edited by: yigiter ]...

Re: voltage selector
as you said i have a printer that runs on 24VDC and i want it to run with either 24 or 12 volts applied. And i don't want to have to select it, i want it to deal with it automatically. also my dc-dc converter is only for 12VDC +/-%5 input. so i mıst keep 24VDC off my converter. i know i can do it us...

Re: voltage selector
hello again,
i have posted a block diagram to make more clear. i've painted the needed circuit in blue. also the the needed circuit must be avaliable for high current(5Amp for 24VDC and 10Amp for 12VDC)
tahanks for your helps..<p>

voltage selector
hello, i am looking for a circuit which switches according to input=12V or 24V. i mean, if the input is 12V, it will forward the input to A, if the input is 24V, it will forward the input to B. i know, i can do it using relay but is there a way to achieve it without of using relay?<p>(look like a mu...

Re: Timer Question
i don't know the optimum solution, but you can achieve it using a microcontroller if you have a little experience with it. connect the output of light sensing circuit to the microcontroller and track that pin. when the output is active, start the timer and at the end of the time, switch the main vol...

Re: dc-dc converter
i have found a datasheet about National's LM2588. it is a 5A flyback converter and you can use it as a boost regulator. it has a circuit drawing for 12V to 24V boost regulator (Figure 38)but it is for 1A current. maybe you can help me to increase current value for 5A. it has not got any information ...

Re: dc-dc converter
the real project is that: i have a power supply who supplies 24V from 220VAC and i want to charge my 12V battery with it. but also i want to use the charger in my car, so if i am at car and so if i can't use my power supply, i want to charge my battery with "12V car battery". i mean, it wi...

Re: Current source
windmiller:
i want to ask two question about your drawing.
1)what is the equation about current?
i=Vin/Rsense?
2)How can i find difference amplifier that you mentioned.
