Mouse fuss around statics

    Outside the window, the green color gradually gave way to white, the atmosphere in the rooms became dry and electrified. How can we save our warm and gentle rumbling pets from terrible statics, ready to destroy their terabytes and gigahertz? I want to share one old enough (I did this if my memory serves me 15 years ago), but from this no less effective way.

    So, the question is - what do you most often grab first, sitting down at your computer? I suggest: a cup of tea and a cigarette are incorrect answers. The correct answer is a small red-eyed rodent. So we will call to our aid this modest hard worker of the desktop. You understand that not every mouse is suitable for us, we will postpone the options with bluetooth and other radio with regret.


    In addition to the mouse, we need a few more things:
    • A small soldering iron - since you are reading this blog, you probably know which side they are taking on.
    • 5 cm of stranded wire, I used MGTF, but with no less success you can take one of the veins of a patch of Ethernet, consisting of several thin wires inside
    • 50kΩ-10MΩ resistor - you can pick out any old board. Both output ones will do (then use the Color Table to determine the face value ) and SMD - their face value is indicated in the form of three digits, look for the one with the last digit 3, 4 or 5. The USB connector is included in the photo specifically for you to imagined that it was necessary to solder.
    • A piece of tape

    So, everything is ready for work, we perform an autopsy of the patient: Here, pay attention to the wire that connects the mouse to the computer. With a high degree of probability, this cord will contain black wires or a shielded wire assembled in a bundle:



    We carefully examine the printed circuit board to make sure that it is still an earth wire. If the Chinese pedigree of the mouse is not very striking, then you will notice that this conductor is much wider in width than the others. We find on it a conveniently located contact pad and solder one end of the resistor. Do not worry if the resistor lies on other conductors - the green garbage on the board (actually called the “solder mask”, but for the sake of clarity, I’ll turn on the “blonde mode”) is quite durable and non-conductive. We solder our piece of wire to the second contact of the resistor, having previously cleaned it.

    Everything is ready, now the most difficult part of the work is to assemble everything so that there are no extra parts left and the mouse works normally. Outside, a real fluffy tail remains to stick out - now it grows in the mouse from the right side! It remains to fluff up the hair on it and fix it with tape: Now, just touching the mouse, all the static electricity that you hardly accumulated through the current-limiting resistor will slowly (but quickly enough) drain into the land of eternal dreams. Of course, extremals and masochists can do without a current-limiting resistor, but this, as they say, is an amateur. Well, for a good mood, a joke in the subject: A fuel truck is driving along the road. Stops his traffic cop. Examines carefully, goes around, looking for something to complain about. Suddenly he notices a chain. He to the carrier:






    - Why chain?
    Drove begins to explain: static electricity, gasoline, spark, explosion hazard, grounding, all that ... The traffic cop listens attentively, then interrupts:
    - I understand that, but why the chain?
    The driver of a fuel truck starts again: static, spark, gasoline ...
    Policeman:
    - what are you talking about sparks? Tell me why the chain!
    In desperation, the driver of a fuel truck catches a taxi passing by and rushes to the taxi driver:
    “Brother, help me, explain to this guy what for I have a chain on my fuel truck!”
    A taxi driver cuts through the situation and says to the traffic cop:
    - Yesterday a new decree came out, everyone to ride with chains.
    Policeman brightens his face:
    - Ah, the decree ... I see. Fuel truck - free! - and turns to the taxi driver: - Why are you without a chain ?!
