Hi,
I came across a circuit which can be used to drive a laser diode in continuous mode (CW) or modulated (<=100Khz).
A BFR540 (NPN) transistor is used to drive the laser diode and a photodiode (inside the laser diode package) provides an output current based on the optical output power, which...
Our client uses some third party softwares and devices for their internal work. They print 600 pages per shift and now they wanted to eliminate paper usage without changing their existing systems.
There are LaserJet printers that are connected with Desktop PCs and Thermal printers that are...
Hi everyone.Here is a a circuit showing how a "PWM Solar Charge controler" works. the principal work of this controler is using arduino's PWM to switch on the transistor 2N3904 to let the 12V battery absorb the energy from the solar pannel when the voltage of the solar pannel is bigger than the...
Hello
I am hoping someone can help me as I am pulling my hair out trying to figure this out and have tried following the limited information I can find about this online but like a lot of the information the steps given are not always complete which makes trying to figure something out as a...
Looking into the datasheet of the IRAMX20UP60A, I found a typical application connection which I am trying to understand. I attach a picture of the application circuit. The part inside the black square is what I don't understand. As far as I understand, if a low signal goes into the base of the...
Greetings,
I have several Sanyo Denki Py2 amplifiers (with BL Super P5 motors) , but dont have the PY-PC Interface Software (PYIF ).
If anyone has this software (Ver 1.3 or higher), please share.
