just use two transformer in series if u r a hobbyist n not want spend much... hihi
if u r manufacture.. go n order transformer with primary 300 v n secondary in ratioed of that 300..
next design good regulation :)
simple as best.... i.ve done this in a village of my neighbour
In my led panel, used inducter ;)
try it rahul.. it this time not damaged near 1 week... lol
b4 i ve burnt many..
used metalise polyster cap supply with bleeder resistor, then bridge, then inducter, then cap, then clamping, then mosfet timer with cap charge timing delay on, now here is my sweet...
if u have only one push key in your design then it can do your work in following manner
system colour change by x= x+1 with condition x=10/11/12 whatever makes x=1 again
where 1 to 10/11/12 are colour combinations ++++(at first if system on then x = 1)[never make x 0 Bcoz]++++
code start
x=0...
first of all think about how sensitive you gonna make it then you have to use those tricks accord to level u wanna do
it can be toy like to properly designed those of government agencies like
your button is going to set a variable,s value for which you have decided any particular color from pwm in code
switch press pin high (now in interrupt ------ ,set a bit only ,exit)
now in code poll for this ,[(bit = 1 ) AND (pin = 0)] now clear bit, inc variable
hope you got it
stoyanoff if u say cheap then what u think about any laser diode 5% to 9% duty cycle on 38Khz in front of tsop1736.
(I show this trick to my gf last week with a cmos counter circuit.)
prashant bhai try kro
* individual leg for each colour _____easy ok
* every pin need pwm for individual brightness __________tricky (interrupt with only one timer) google for this techniqqq
* also make x variable increment to see what the time for next throttle action_______(secret open)
*...
it depends on your application.are you going to use usb feature too.
you can also try some bluetooth modules if want to interface pc laptop
with a vb code
if you are not using usb then no need to use that 4550,any cheap handy controller also can do such work
hey frn , one time i developed automated thing like this
and you have also mentioned that you are using mcu
so
1.you get solar cell's____ adc val
2.you get battery_____ adc val (use reference voltage)
3.add a big cap directly on solar cell, then make your mosfet switches your
solar cell...
