Hello,
we are doing ICSP with PIC12F629, and are using a 2.54mm pitch programming header......i.e. this one...

this goes with this crimp housing...
Hello,
I am trying to order a yellow Power TopLED.
Power TOPLED datasheet.
**broken link removed**
The part number begins with the letters "LY E6SF"
...The subsequent letters indicate which Wavelength group or brightness group it is.
Also, if there is a "-1" at the end of the part number...
Hello,
I was modifying a PCB layout of a LED Driver PCB on which the leds are also mounted.
The modification was just to add a few resistors and capacitors to provide a sync function.
However, somehow, the board outline has moved and i have no idea how this happened...i never moved the board...
Hello,
We have four flashing LED lamps , each mounted at different parts of a lorry.
Each Lamp has a PIC12F683 microcontroller in it.
The four microcontrollers all have their GP4 pins connected together by a wire.
….The microcontrollers use this wire to send and receive pulses to each...
Hi I am doing an electronics test sheet, and it wont let me insert a column of cells, as it says theres not the room.
Its an .xslx sheet
do you know how i can do this, it says something about deleting cells from the end of documet but that doesnt seem to work.
do you know how to insert a...
ok thanks, i imagine that a measuring device which can accurately measure light output when the flash only happens for 200us every 800ms is going to be very expensive.?
FvM i see what you mean but we have a standard way for measuring where the lamp has no diffusor over it and is operated at...
Hello,
We have 3W xenon flashlamps which flash once every 800ms
The flash looks to be quite long, but in fact the tube current flows literally for just ~200us for each flash.
Recently, we doubled the trigger voltage (making it correspond to that required by the tube) and the light output...
Hello,
i dont have room on pcb for component designators, but still want some silk sceen markings...how do i remove component designators?.....they are on the silkscreen, but i cant just make silkscreen invisible as i still want silkscreen
Hello,
Please help me find Current required to drive FET in buckboost converter
I am using SiS892DN mosfet in 1MHz buckboost converter LED driver.
Vin = 27V
Vout = 58V with respect to ground (though leds are returned to vin)
Fsw = 1MHz
Controller = LT3755
FET gate drive voltage = 7.15V
Iled...
Hello,
The question refers to the LT3082, whose datasheet is here...
http://cds.linear.com/docs/Datasheet/3082f.pdf
....i want it for 5Vout, and my load current is about 250uA for long periods......will Vout drift above or below 5V, and by how much?
OK thanks, so do we say that in fact, a lorry "bus" voltage, due to the series connected car batterys is thus 27V?.......because a car battery is not really 12V, but is in fact 13.5V
(I dont know why people say car batterys are "12V", because they never have been.(?))
Hello,
We need to program an S08 PIC microcontroller before soldering it into the board.
(there isn’t enough room on the PCB for the ICSP connector)
Do you know if anyone sells something that allows us to do this?
Hello,
any more details on theis LED lamp.....SD24 by strobe.com?
https://www.youtube.com/watch?v=zq2pqH5irp0
I wish to know the LED current value on steady burn (whether its the same as when flashing), and the flash frequency.....it says "deci-flash" but just how fast is the flash rate of...
