How do I use a laser sensor?
Hello, I have a small project and wanted to ask how to connect a laser sensor like in the picture, for example, to a lamp and what the third white cable on the other sensor is for. I hope someone can enlighten me. Thanks in advance 🙂
Service front derailleur?
There are numerous videos on YouTube showing people disassembling, cleaning, and expertly reassembling their rear derailleurs. There are no such videos for the front derailleur. Is there a reason for this? I would like to do that with mine sometime.
Convert 12V/2.5A to 5V/6A?
ByNoayHD
I have a USB-PD power supply that can only output 3A at 5V, but 2.5A at 12V. Can I get the full 30W at 5V with a voltage converter and a USB-PD chip?
Who was the real inventor of the light bulb?
Good day dear ones, Who is the real inventor of the lightbulb? Of course, everyone knows it's Adison, but I remember hearing on The Big Bang Theory that it wasn't him. I also read that it was Heinrich Göbel, but I wanted to ask if that's true and if it really was Göbel. Best regards
I would start like this: U1+U2=18V-Ur4-Ube
Where Ube can never be 2V, it would result in immediate smoke signs.
So, m. E., this would be like this:
U1+U2=18V-3V-0,7V=14,3V (also corrected – instead of + )
So you can calculate the current through R1+R2.
Update: Can use 2V instead of 0.7V, but this is definitely the end of the transis. 😉
If you then know the R1+R2 current, you can take the Bn for the collector current.
Here is the entry code field Ube:

Thank you! It worked.
First of all: not at all, because at 2V base-emitter voltage, each bipolar transistor is simply broken. So, as the creator of the task apparently has a damp throat around reality, one can easily count on it.
Yes – the taskman is not very close to reality. The series and parallel circuits are already arbitrary. Not to mention the 2V between B and E. The term “reinforcement factor” is also quite unusual.
