At 5V you can put 2 or 3 LEDs in series.
Use a digital or video camera to see them work.
LED in series with 100 Ohm resistor. Increase the voltage of a variable power source until you reach the nominal current e.g. 20 mA. Measure the foreward voltage at the LED with a multimeter.
It's not so easy to calculate start frequency and acceleration. It depends on mass to be accelerated, motor power and friction of the mechanical drive. Also resonance can be a problem.
I would suggest the try and error method.
First try out the maximal start frequency (the frequency at which...

Hi
you could also have a look at Altium. They have a complete design-tool for Altera or Xilinx FPGAs/CPLDs. I have actually bought the live design kit (Xilinx version €99)

Hi monnoliv,
what's about the given url? I've tried several times but never succeeded to connect. Is this a personal or German problem. Who is able to connect to

mscomm test
Start with polling using a timer-routine by testing the property 'InBufferCount' to see if characters are received. Read with 'Input'. - I had problems with the Comm-event.
Hi,
download the free program SwitcherCAD from here https://www.linear.com/software/
Start the software, put in your needs and you'll get the schematic together with power consumption efficiency etc.

I think you'll have to disassemble the first one for experience (make some photos). After that you can handle the following ones with success.

It can be done but its a dirty work. I used toner from the collector-unit of several empty cartridges, sieved it and filled the toner into one of the used cartridges. it worked well.

Hi,
you will need some API-calls
to get the handle of the window you want to close:
Declare Function EnumWindows Lib "user32" (ByVal lpEnumFunc As Long, ByVal lParam As Long) As Long
Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long...
