I agree too many unknown things and different options
of course this 2 strips are in paralel each of them have 72 led diodes
each 2 diode are with resitor,checked with meter 2 light so 2 are in paralell how i already explain
.Well i will find transformer and checked it with power supply
Well maybe ..you must know i don't build this strips .they are fabricated probably in China...
section of 2 led diode and resistor are in parallel with DC power rail ,so there is 36 sections in one strip
inside plastic tube there are 2 such a strip, and you probably see...
@ZASto that is good idea...how is connected...it is on the image in above post!
This is my simulation
If the resistor is 1k then current is 16 mA...but is almost impossible to tell what kind of led diodes are used in strip i can guess 3.4V
First .thanks for reply
I am not a kid ,i fixed many electronics radios,TV but never such a things like LED lights
you asking about how diodes are connected i already show you on a given image from (+) goes one diode then i guess is resistor in serie then another diode ,all that in...
Hi ...that i know requirement for this strips then i don't ask,,but i dont know and there is no any data we can found on internet.
This is slim flat 2 strips tube ,replacement for standard fluorescent light 120cm length.
it is powered by mains 220AC ,driver is broken-burned because of cheap...
There is no need to worry about quality of 741 ( i have few which are still working ) in metal case
here is good one :
I recently found on github open source electronic simulator called CanEda.
Program is based on QT and looks that work fine on my windows 7 machine.
But i cannot found documentation and any examples how to work with
this simulator ..
Is anyone here who have experience with this new program...
This receiver can work in two mode.
As regenerative or super -regenerative what depends on base current biasing.
Most of zero IF receivers are synchro-dyne types and as such are not in co-relation with pulse-counting
detectors.Pulse counting receivers are not zeroIF types than use very low IF...
There is a nice schematic in Fig.5, but the loop is hand sensitive. To overcome this disadvantage and because i dislike tapped coils,
i've synthesized an aperiodic preamp like in Fig.6 and an colpitts-like common base oscillator with feedback from collector to emitter,
coupled them by small C...
